  • EXECUTIVE SUMMARY

    This report presents the outcomes of the nutrition assessment conducted in The Gambia across the eight

    Local Government Areas to assess the nutrition and mortality situation of its population. UNICEF

    Gambia commissioned the assessment, with financial support from ECHO and UKaid and in

    collaboration with the National Nutrition Agency (NaNA). The fieldwork of this assessment was

    conducted from 1st September to 6th October 2015.

    The Gambia is located midway on the bulge of the West Africa Coast and stretches over 400 kilometres

    inland from west to east on either side of the River Gambia, varying in width from about 50 km near the

    mouth of the River to about 24 km upstream. The country is bounded to the north, south, and east by the

    Republic of Senegal and to the west by the Atlantic Ocean. The Gambia’s climate is typically Sahelian,

    with a long dry season from November to May and a short rainy season between June and October.

    The Gambia continues to face rising malnutrition rates linked to chronic food insecurity and a

    deteriorating ability of rural communities to cope due to recurrent drought crises. According to the

    Harmonized Framework Analysis done in March 2014, roughly 14 per cent of the population were in the

    emergency phase of food insecurity. Factors driving this humanitarian situation include poor harvest;

    increasing commodity prices; recurrence of epidemics and other natural disasters; chronic shortage and

    limited access to basic social services; and the near total absence of relief support to the affected

    population.

    The National Nutrition Agency, through technical support from UNICEF, conducted a National Nutrition

    Survey using the Standardized Monitoring and Assessment of Relief and Transition (SMART) methods to

    estimate the levels of malnutrition among children under five and pregnant and lactating women in The

    Gambia as a follow up to the 2012 National Nutrition Survey.

    The 2015 SMART Nutrition Survey collected and analyzed anthropometrical data from children 6-59

    months of age and women of reproductive age as well as household composition and mortality data.

    Specifically the survey assessed the following:

    1. the prevalence of acute malnutrition (including prevalence of bilateral oedema) of children 6 to 59 months

    2. the prevalence of chronic malnutrition and underweight of children from 6 to 59 months 3. the prevalence of low BMI, obesity, acute malnutrition (MUAC) in women of reproductive age

    groups (15-49 years of age) 4. the crude and under-five death rate

    The survey was designed to present results at the Local Government Authority (LGA) and national levels.

    A SMART survey methodology with two-stage cluster sampling was used to generate nutrition and

    mortality data in the 8 LGAs in The Gambia from September 1st to October 6th, 2015. A total of 251

    clusters were selected using a Probability Proportionate to Size (PPS) method. Data were collected from

    4017 households and 4830 children were assessed.

    The national prevalence of Global Acute Malnutrition (GAM) was 10.3percent [95% CI: 9.1 –11.5] and Severe Acute Malnutrition (SAM) was 2.2 percent [95% CI: 1.7 – 3.0]. These results were higher than

    those reported by the 2012 SMART survey which had a GAM prevalence of 9.9 percent [95% CI: 8.8 –

    10.8] and SAM prevalence of 1.6 percent [95% CI: 1.2 – 2.0]. The prevalence of Global Acute

    7

  • Malnutrition of 10.3percent GAM (-2 Z-score) with a mean of (-0.78) falls above the WHO classification

    of serious threshold of 10 percent. The table below shows the summary of indicators assessed by this

    survey:

    Table1 Summary of Indicators

    Indicator Results Demographic Total No. of HHs Assessed 4,017 Total number of children analyzed for Anthropometry 4,830 Male 2,432 Female 2,398 Average number of persons per households 8.6 Nutrition Status of children 6-59 months Global Acute Malnutrition (WHO 2006) 10.3% (95% C.I. 9.1 – 11.5) Boys 11.1%(95% C.I: 9.6-12.8) Girls 9.4% (95% C.I: 7.7-11.5) Severe Acute Malnutrition (WHO 2006) 2.2 % (95% C.I. 1.7–3.0) Boys 2.8% (95% C.I:2.0 -4.0) Girls 1.6% (95% C.I: 1.6 -2.4) Proportion of Children Stunted 22.9% (95% C.I: 21.0-24.8) Boys 24.5% (95% C.I: 22.1-27.1) Girls 21.2% (95% C.I: 18.9 -23.7) Proportion of children underweight 21.6% (95% C.I: 19.7-23.5) Boys 22.2% (95% C.I: 19.9 -24.8) Girls 20.9% (95% C.I: 18.5 -23.5) Nutrition status of women aged 15-49 years Proportion of non-pregnant women under-weight 17.7% Proportion of non-pregnant women over-weight 14.9% Proportion of non-pregnant women obese 9.2% Proportion of pregnant women wasted 3.7% Mortality Rates Crude Death Rate 0.67 (0.56-0.79)deaths/10,000/day Under-Five Mortality rate 0.85(0.58-1.23) deaths/10,000/day

    The current acute malnutrition prevalence (10.3%) is above the 10 percent serious threshold as per WHO

    classification of malnutrition. Maternal and child under nutrition was high in the LGAs of Basse,

    Kuntaur, Kerewan and Janjanbureh which might contribute to increased mortality and overall disease

    burden in these Local Government Areas.

    The high burden of malnutrition among children under five and women of reproductive age led the author

    to recommend that interventions be focused on these target groups particularly in the first 1000 days of

    life. The following nutrition-specific and sensitive actions which are believed to contribute to the

    improvement of health and nutritional status of populations at household levels are recommended:

    v Promotion and counselling to improve early initiation of breastfeeding and increased duration of exclusive breastfeeding.

    8

  • v Appropriate complementary feeding, including a sufficient intake of micronutrients is essential v Supplementation programmes for vitamin A and zinc are effective for improving micronutrient status

    of children and reducing incidence of some diseases and deaths. v Fortification of foods with micronutrients has also been shown to be effective at improving

    micronutrient status of children

    v Scale up treatment of SAM through the IMAM Program

    v Strengthen nutrition sensitive interventions to address the underlying factors that contribute to malnutrition, including hunger, poverty, gender inequality, and poor access to safe water and health services by integrating nutrition actions into other sectors

    v Strengthen production and utilization of diversified nutritious and drought -tolerant crops

    v Conduct a coverage survey and bottle neck analysis to identify barriers to service delivery and uptake

  • Chapter1:Introduction

    1.1 Background The Gambia has a population of approximately 1,979,743 (GBoS 2013) and is a low-income country with high poverty levels that contribute to the increasing vulnerability of its population to shocks. An estimated 71 per cent of the population live below the US$2 per day, (2014 human development index)i The prevalence of undernutrition in The Gambia in all its forms has not improved over the past decade and is actually worsening. The findings from the 2012 national nutrition survey reported the Global Acute Malnutrition (GAM) and Severe Acute Malnutrition (SAM) rates of 9.9% and 1.6% respectively (Gambia NNS 2012).The survey also reported that more than 43.3% of mothers are malnourished (NNS 2012 survey), about 18.7% of women of childbearing age were underweight (low body mass index), 2.6% severely underweight, 15.1% overweight and 6.9% obese. The Gambia Demographic Health Surveys (DHS) in 2013 reported that 24.5% of children under five were stunted, 16% were underweight and 11.5% were wasted while 4.2% were severely wasted. Micronutrient deficiencies are also a common public health problem with notable ones being Vitamin A deficiency, iron deficiency anaemia and iodine deficiency. In 2013, the Demographic Health Surveys (DHS 2013) estimated that 73 percent of the children in The Gambia suffered from some level of anaemia with 4 percent being severely anemic. The prevalence of anemia was higher among children in rural areas at 78% compared to 67%in urban areas with Kuntaur having the highest proportion (85%). The study also showed that rural women were more likely to be anaemic (68%) compared to urban women (53%) with more women in Kuntaur and Janjanbureh being anaemic (74%). Major predisposing factors for under nutrition include over-dependence on subsistence rain-fed agriculture and consumption (insufficient dietary diversity) coupled with the high poverty, low literacy levels and the high prevalence of morbidity malaria, diarrhoeal diseases and acute respiratory infections,. Under nutrition weakens the immune system, stunts physical growth and cognitive development and can

    have a lifelong and intergenerational effect on educational attainment and economic potential for

    individuals, families and nations. It has been estimated that co-exposure to a range of related factors

    which have under nutrition as their underlying cause (including a weakened immune system and

    susceptibility to infectious diseases such as malaria, diarrhoea and pneumonia) combined with the effects

    of growth restriction, micronutrient deficiencies, and sub-optimum breastfeeding account for 45 per cent

    of all child deaths (Black et al. 2013). The consequences of stunting and cognitive development tend to be

    irreversible after the age of two, with the period from conception until a child’s second birthday being the

    first 1,000 days ‘window of opportunity’ to prevent irreversible damage. Children who are

    undernourished in the first two years of life and who put on weight rapidly later in childhood and in

    adolescence are at high risk of chronic diseases in adulthood.

    Maternal under nutrition and the stress this causes upon the foetus in utero (in the womb) can increase the

    risk of intrauterine growth retardation (causing babies to be born Small-for-Gestational Age - SGA), and

    can have long lasting effects on the health of an individual throughout the life course, and longer term

    10

  • implications for chronic diseases including cardiovascular diseases and type II diabetes (Victoria, C., Adair

    et al2008).

    The Government of The Gambia is committed to improving the nutritional status of the people of The

    Gambia with special focus on the vulnerable groups such as infants, children under the age of five years,

    pregnant and lactating women. The country puts adequate nutrition as a major contributing factor in

    attaining the Millennium Development Goals (MDGs) and vision 2020. The revised National Nutrition

    Policy (2010-2020) will contribute significantly to improving the nutritional status of the Gambian

    population and thus help in achieving the Sustainable Development Goals (SDGs) and vision 2020.

    1.2Justi�icationoftheNationalNutritionSurvey2015As malnutrition is a significant contributor to child morbidity and mortality, it is critical to have quality,

    relevant and timely information to monitor the nutritional status of children under five and other

    vulnerable groups. Thus, the need for regular monitoring of the nutritional status of children across the

    country is a crucial step that helps to assess the country efforts in meeting global targets (WHA, SDG’s)

    as well as national targets. The National Nutrition Agency (NaNA), in collaboration with UNICEF and

    other stakeholders, proposed a national nutrition survey using the Standardized Monitoring and

    Assessment in Relief and Transitions (SMART) method during the same period the 2012 National

    Nutrition Survey was conducted to generate standardized data on nutrition and mortality. The National

    Nutrition Survey will provide data for timely action, program planning and long-term monitoring for the

    government, donor communities, public and international communities working in the health and

    nutrition portfolio in the country.

    1.3 Objec�ve of the survey

    The general objective of the National Nutrition Survey 2015 was to provide an informed analysis about the nutrition situation in The Gambia. It would also contribute to the effective planning and implementation of nutrition interventions (nutrition specific and sensitive programs).The specific objectives of the survey were to assess:

    1. the prevalence of acute malnutrition (including prevalence of bilateral oedema) of children from 6 to 59 months

    2. the prevalence of chronic malnutrition and underweight of children from 6 to 59 months 3. the prevalence of low BMI, obesity, acute malnutrition (MUAC) in women of reproductive age

    groups (15-49 years of age) 4. the crude and under-five death rate

  • Chapter2 Methodology

    2.1. Sample Size Standardized Monitoring and Assessment in Relief and Transition (SMART) methodology was employed

    to undertake the nutrition and retrospective mortality survey.

    The Emergency Nutrition Assessment (ENA) for SMART version (July 9th, 2015) was used to determine

    the sample size after entering the sample frame data. For quantitative data collection methods, sample size

    calculations were made to ensure that key indicators were statistically representative at each LGA.

    For anthropometry sample size estimation, statistical parameters such as 3.0% desired precision was determined to be reasonable to detect estimated prevalence of malnutrition for all LGAs. A design effect of as low as 1.2 was also used for all LGAs with possible homogeneous composition except for Brikama which was expected to have a higher design effect, due to livelihood differences expected between urban and rural dwellers so a 1.5 design effect was used to inflate sample size estimates and to compensate for cluster sampling. Other factors such as respective average household size of each LGA and an expected 5% non-response rate was used to calculate anthropometric sample sizes.

    The sample size for the mortality survey was also calculated using the ENA for SMART software. The

    mortality rates from the 2012 National Nutrition Survey were used to detect expected UMR and CMR.

    Additional inputs such as 407 days recall period, a design effect of 1.2 for almost all LGAs except for

    Brikama with a DEFF of 1.5 were keyed into the ENA for SMART software. Other factors such as each

    LGA’s respective average household size and expected 5% non-respondent rate were used to calculate the

    intended sample size for the mortality survey. Tables 2 and 3 below provide a summary of inputs for

    sample size calculation for both the anthropometric and mortality surveys.

    The sample size for the anthropometric survey was calculated as 4,166 households while the sample size

    for the retrospective mortality survey was calculated as 899 households. However, since the

    anthropometric survey sample size was the higher of the two, the final sample size for this survey was

    taken as 4,166 households.

  • 2.2 Sampling Procedure for Household Survey

    2.2.1 Sampling Frame

    The master list which was provided by The Gambia Bureau of Statistics (GBoS) considered as the latest

    sampling frame for this survey consisted of approximately 1,979,743 population from a total of 4,838

    EAs (GBoS database, 2013). A two stage cluster sampling methodology was employed. The first entailed

    the selection of 251 clusters using the probability proportional to population size technique, while the

    second stage entailed the random selection of households.

    (1) Selection of Primary Sampling Units (Clusters)

    (2) Cluster and Household Selec�on

    In this survey, Enumeration Areas (EAs) were considered as the clusters and were the smallest

    administrative unit. The clusters were selected using the probability proportional to population size (PPS)

    where all the villages alongside their population were captured in the ENA for SMART (July 9th, 2015)

    Software and 251 clusters selected. On arrival at the village, first each team leader followed the local

    community entrance procedures and explained the objectives and the methodologies of the survey to the

    clan/village leader known as ‘Alkalo’ and sought his approval before data collection commenced.

    Households were selected using systematic random sampling. The survey teams then demarcated and

    confirmed the actual location of selected EA and systematically divided the EA while at the same time

    enlisting actual residents within the demarcated zone. The teams then met with their respective supervisor

    and together combined all listed HHs from the cluster and prepared one sampling list for HH selection.

    All children 6 to 59 months found in the selected households were included in anthropometric survey.

    Respondents were primarily household heads or, in their absence, whoever the household recognised as

    head was interviewed to get all relevant information.

    Case Definition and Inclusion/Exclusion Criteria

    The Global Acute Malnutrition (GAM) is the index used to measure the level of wasting in any given

    population. In this survey, GAM was defined as the proportion of children with a z-score of less than -2

    weight-for-height and/or presence of bilateral oedema. Severe Acute Malnutrition (SAM) was defined as

    the proportion of children with a z-score of less than -3 and/or presence of oedema as summarized below:

    Malnutrition by Z-Score: WHO (2006) Standard • Severe acute malnutrition is defined by WFH < -3 SD and/or existing bilateral oedema

    • Moderate acute malnutrition is defined by WFH < -2 SD and >-3 SD and no oedema

    • Global acute malnutrition is defined by WFH < -2 SD and/or existing bilateral oedema

    Malnutrition by MUAC • Severe malnutrition is defined by MUAC

  • Body Mass Index, WHO 2004 Standards

    Classifica�on of BMI

    BMI (Kg/m2) cut-offs

    Severe underweight =25.0

    Obese >=30

    All children 6 to 59 months and women of reproductive age in selected households were included in the

    anthropometric survey. Primarily the inclusion criterion was age; this was first determined by looking at

    the child welfare cards and birth certificates and in their absence, age was estimated using local calendar

    of events. See Annex 1 for a local calendar of events prepared for the Gambian context and used during

    the survey data collection.

    2.3 SurveyTeamsNine teams of four people (1 supervisor, a team leader and 2 measurers) were recruited by the National

    Nutrition Agency (NaNA). See Annex 5 survey team database and organogram.

    2.4 TrainingA total of thirty-six surveyors were trained at NaNA conference hall from 26th to 30th August, 2015

    facilitated by the Nutrition Survey Consultant and NaNA core staff. The first three days covered

    theoretical concepts of the SMART methodology while the last two days were for field exercises. A

    training guide and power point presentation adapted from SMART methodology were used. The training

    course covered the following areas: taking anthropometric measurements, conducting mortality surveys,

    sampling steps and procedure, filling out questionnaires, approaching the community, common possible

    errors in surveys, data entry using SMART (ENA Software) and interpreting data quality. Before

    conducting the pre-test survey, all equipment and enumerators’ skills were double checked by

    standardization exercise to ensure consistency of the anthropometrical measurement using ENA for

    SMART. Based on such evaluation of enumerators, none were excluded due to inadequate accuracy.

    Results of standardization test is in annexed 3.

    2.4.1 Pre -Testing and Revision of the Survey Tools Before the commencement of the actual survey, tools and methods were pre-tested and revised. A two-

    day pre-test survey was conducted in one of the non-selected villages/EA in New Jeshwang, Old

    Jeshwang and Tallinding located in the Kanifing Municipality. The pre-test included steps of sampling

    and anthropometry and mortality data collection. This helped to ensure that the interviewers understood

    the questions in English and could interpret them into the four major languages and were able to follow

    the interview/data collection procedures as outlined during the training. Based on the pre-test survey and

    standardization during the training, the nine survey teams were formed and the teams then revised the

    questionnaires.

    15

  • 2.5 DatacollectionTwo sets of questionnaires with all the described variables herein attached under annex 6were used to

    collect the data from all the households (annex 6). Secondary data was obtained through desk reviewing

    and conducting Key Informant Interviews.

    Household: A household in the Gambian context was defined as a person or a group of persons who

    usually live together (within the same compound) and share the same cooking/catering arrangement.

    In migration: In-migrants at the household level were described as persons found in a household who

    were not usual household members but planned on staying with the household for a relatively long period

    of time (6 months). This excludes visitors who just came to spend the holiday, celebrate a feast or were

    visiting for a short period of time.

    Out-Migrants: Out-migrants at the household level were described as usual household members who

    were absent during the period of the survey who planned on staying away for a relatively long period of

    time (>6 months). This excluded usual household members who had travelled for a short period of time.

    2.5.1AnthropometricMeasurement

    Children 6-59 months were assessed for weight, height/length, Mid Upper Arm Circumference (MUAC)

    and the presence of oedema. Most children were weighed either naked or with light clothes. If the

    children were measured naked or only with very light short pants, then an adjustment with a standard

    correction factor of 30gm was applied for weight of clothes. The children were weighed using the Seca

    881 digital scale with 100 grams precision. For children that could not stand, their weights were

    measured with their mothers or caregivers using the tarring process.

    For children younger than two years of age or less than 87 cm, length was measured to the nearest 0.1

    centimetre in the recumbent position using a standard Shorr height board. Children 87 to 110 cm or above

    2 years were measured in a standing position. Oedema was assessed by applying thumb pressure to the

    feet for approximately three seconds, and then examining for the presence of a shallow imprint or pit.

    Malnourished children were referred to the IMAM programs for treatment of moderate and severe acute

    malnutrition. Women of reproductive age (15 - 49 years) were also measured for MUAC, weight and

    height.

    2.5.2RetrospectiveMortalityRecordings

    Mortality was assessed using the retrospective household census method. As per the SMART guideline

    for collecting mortality data, the 2015 survey collected mortality information both at the household and

    individual level. The beginning of the recall period was on 4th of August 2014 (beginning of last year

    Tobaski feast) and the end point was midway between the first day of the survey date and the last date of

    the survey which was September 15th of 2015. Respondents were requested to list all members living in

    the household as of 4th of August 2014 till the last day of the recall period. First, all members living in the

    household at that time were listed by age and sex, with the head of the household listed first. The

    respondents were then asked where each person was at the time of the interview. Possible responses were:

    alive and living in the household, alive and living elsewhere, missing or dead. Deaths occurring in each

    household in the period were recorded along with the date of occurrence. Cause of death was collected

    from the respondent, if not the head of the household. Each questionnaire had descriptions of the causes

    16

  • of death listed; and codes included illness, injury/traumatic, unknown and options for location of death

    would either be at home, abroad, at health facility or others.

    2.6DataCollectionandQualityControlThroughout the field work, rigorous quality control measures were adopted. The Seca 881 digital scale was checked daily with known weights before starting the field work. Supervisors checked the

    questionnaires at the end of each day, identified errors and made sure data collected was correct before

    signing off and keying the raw data into the software. Each team supervisor was requested to complete

    and submit the cluster report together with the completed questionnaires on a daily basis. Each team was

    informed before the following day about the quality of the data collected the day before. As and when

    needed, a meeting between survey coordinators and supervisors was organized to review the work done,

    discuss common errors, and avoid recurrences and to plan for the next day.

    2.6.1 Steps Taken to Minimize Bias (on site)

    The reduction of any potential bias during the implementation of a survey is vital to ensuring that the data

    is of good quality. The following were measures taken to help reduce the incidence of bias:

    § Strict use of age records for inclusion of eligible children using infant welfare cards and birth

    certificates and, in their absence, use of local events calendar to determine the age in months of the

    children;

    § Configuring each supervisors laptop in accordance with the country use of date format

    (DD/MM/YR)

    § Calibrating Seca 881 digital scale with test weight (1Kg filled sand container)

    § The use of MUAC’s tapes with thread attached to determine the mid upper arm circumference

    § Measuring of weight of a child either naked at all-time or applying a correction factor of 30 gm to all

    children measured with some light clothes on.

    § Verification of extreme values (re-weighing/measuring, or returning to households to verify data);

    § Returning to the households if children were missed and/or household members were not at home;

    § Strict supervision in the field by team supervisors and on spot support or backstopping or trouble

    shooting as and when needed by survey coordinators

    2.7 DataManagementData was entered in both ENA Software and EPI info (3.5.3) version simultaneously. All data were

    entered the same day it was collected in the field. This allowed for the data to be immediately available

    for cleaning and analysis. The double data entry and validation was done at NaNA Office from 30 th of

    September to 9th of October 2105 by well-trained Data Entry Clerks from NaNA Office. Consistency

    checks were run to detect and correct data entry errors by referring to the hard copy questionnaires

    The first step of the data cleaning was the examination of the control sheet from all submitted clusters

    (number of times a household was visited, number of eligible children and status of each questionnaire

    vis-à-vis the three questionnaires), the correctness of the logical relatedness between these questionnaires

    to ensure smooth linking between variables from different data sheets during the tabulation work.

    Frequency distributions were then performed on all key indicators to examine the frequency of responses

    as well as to check for missing values. Interpretation of anthropometrical measures using WHO 2006

    17

  • Child Growth Standards was made and introduced to the child data sheet to identify flagged records and

    recheck the entered data of birth date or age, height, weight and MUAC.

    Finally, after the completion of field work and data entry, data was re-checked by the Consultant and all

    questionnaires were tested for errors and inconsistencies related to missing entries and feasibility/outliers.

    2.7.1Consent

    All household members received a verbal explanation of the survey including mortality, household

    questionnaire and anthropometry. The consent or refusal was recorded on the form by the interviewer.

    Households were informed that the survey was confidential, and that their responses would not affect any

    food and non-food distributions. Participation was voluntary and household members had the right to

    refuse to answer any or all questions as well as anthropometric assessments.

    2.7.2DataQualityandAnalysis

    Anthropometric and mortality data were entered and analyzed using ENA for SMART Software of July

    2015, and EPI info 3.5.3. For anthropometric analysis, reference population of the WHO 2006 Child

    Growth Standards was used.

    Anthropometric data was collected for 4,841children nationally and was checked for outliers (values

    identified by WHO flags). Weight -for-height data was analyzed for 4,530 children, height-for-age for

    4,464 children, using ENA for SMART. The plausibility report generated by SMART (ENA) Software

    (Annex 5) scored the overall survey at 9% nationally and by LGA ranging from 0% to 5% which means

    that the survey had good quality anthropometric data for children under five.

    Other anthropometric data such as MUAC and BMI were analyzed using EPI Info 3.5.3 /SPSS program

    (version 21; SPSS, Chicago IL USA). The plausibility report generated by SMART (ENA) Software,

    quality of both mortality and anthropometrical data, a CDC calculator of two-surveys and threshold

    calculators were used. A p-value -0.40 -0.40 to –0.69 -0.70 to –0.99 < -1.00

    18

  • 2.8SurveyLimitations

    Malnutrition Prevalence Estimate:

    The estimates of the prevalence of stunting, underweight and overweight in children in the age range of 6-

    59 months do not follow the recommended age for the indicators. These cannot be directly compared to

    estimates from DHS or MICS as the elimination of the age group 0-5 months of age introduces a bias.

    It was reported that some weight measures of children were taken with clothes on and not following the

    WHO/CDC training or SMART methods. Data were collected on weight measures with clothes on for 54

    children in Banjul. No data were recorded concerning measurement of weight in clothes for other LGAs.

    The consultant entered 30 g as the average amount to subtract from the 54 cases in Banjul. If other

    children were measured with clothes on, this introduces a bias that decreases malnutrition but most

    critically in youngest children.

    Children have recorded date of birth but the dates were not recorded in a rigorous manner. The 15 th day of

    the month was preferred for many children in Kanifing, Brikama, Mansakonko and Kuntaur LGAs. In

    DHS and MICS methodology, when a date of birth is unknown, it is assigned to the 15th of the month.

    This could be a related method. It is odd that this trend is not found in Banjul, Kerewan, Janjanburay and

    Basse. There was a preference away from the birth months of April, May, June and July in the total

    sample. Mistakes in the month of birth of a child can introduce analysis bias that affects stunting,

    underweight and analysis of malnutrition by age in months.

    Age displacement in women has been identified in the NNS 2012 and DHS 2013. Interviewers wanting

    to reduce their workload, changed the age of women to older than 49 years of age to avoid conducting

    interviews. Despite the warnings made in the previous surveys, it appears that supervision was not

    adequate to prevent interviewers from changing ages to reduce workload.

    In the NNS 2015 sample, there was evidence of age displacement by years in children. Interviewers have

    used the same method to avoid measuring children. In future surveys, the use of mobile devices such as

    smart phones or tablets with immediate sending of data to a central database will help to identify and

    address these errors quickly.

    Retrospective Mortality Estimate:

    Recall bias can affect mortality surveys. There was however no remarkable event to coincide with the

    recall period used in 2012 SMART survey and hence a longer recall period of more than one year was

    utilized. This helped minimize the potential recall bias. Also specific local calendars were used to

    confirm the timing of events. The same calendars were also used by enumerators when asking other

    questions on child age.

    Households that have disbanded or where no one was present during the recall period are not included in

    the mortality estimates. Only households in which members were present on the day of the survey were

    included in the sample. Assurances were made during the introduction of the survey to both the

    communities and households that information provided regarding household composition and deaths

    would not affect any future distributions.

    The women’s response rates were near or above 80% in all domains except Banjul. The results for women

    in Banjul could be biased as they represent the women who were at home during the interview. Other

    women outside the home during the interview could be of better or worse nutritional status.

    This section summarizes demographic and socioeconomic characteristics of the population in the

    households sampled in the 2015 survey. The information presented in this section is intended to facilitate

    interpretation of the key nutrition and mortality results presented later in the report. Moreover, it is also

    intended to assist in the assessment of the representativeness of the survey sample.

    Out of the total 4,166 households sampled during the whole data collection period, 4,017 households

    were examined for both anthropometry and mortality. Similarly, out of the total 5,535children under-fives

    enlisted during the whole data collection period, 4,841 children under-fives anthropometrical

    measurement was taken. This showed a 96.4% household response rate, and 80.4% response rate in

    women and an 89.7% response rate in children.

    Figure 1: The Gambian Popula�on Pyramid

    Out of the total 32,151.5 population assessed from the 2015 SMART survey, 47.6 % (n=15,318.5) were

    males while 52.4 %( n=16,833) were females. As per figure 2, almost all age bands of the study

    population had a uniform representation except in age band (50-54) where more females than males were

    recorded.

    22

  • From The Gambia DHS 2013 - The pyramid shows a rather sharp increase in population size between

    women age 45-49 and those age 50-54. To a certain extent, this may be due to a tendency on the part of

    some interviewers to estimate the ages of women as above the cut-off age of 49 for eligibility for

    individual interviews, thus reducing their workload. A similar trend is observed for men aged 55 -59 and

    those aged 60-64.

    · Indication of age displacement in women - poor supervision

    · Reduction of children under five years of age, could be effect of family planning or age displacement

    The problems of age displacement of children under five compared to children 5-9 years of age were found in Kanifing, Janjanbureh and Basse (see annex 3 and 4) and as evidenced in the figure 3 below. These issues will be addressed in future surveys by collecting data with mobile devices and providing greater scrutiny on the household listing to ensure quality anthropometry and mortality data collection.

    The results in Table13 shows the number of children surveyed disaggregated by sex and age. Nationally,

    the sex ratio comprised of equal proportion of males and females with the overall ratio of 1:0 female to

    male which indicates that there was no significant sex bias in the survey. The overall age ratio between 6-

    29 to 30-59 is 0.80 which is very close to what is normal in a stable non-emergency population (age ratio

    should be about 0.85)

    3.2 ChildAnthropometry(6-59months)For estimating the prevalence of wasting, chronic and underweight prevalence, WHO flags were used.

    3.2.1GlobalAcuteMalnutrition

    Table 13 above shows that anthropometric measurements were analysed for 4,830 children. The results

    presented are based upon weight-for-height z-scores and the presence of nutritional oedema. For the

    overall sampled population, the prevalence of Global Acute Malnutrition (GAM) was 10.3 percent [95%

    CI: 9.1 –11.5] and Severe Acute Malnutrition (SAM) was 2.2percent [95% CI: 1.7 – 3.0]. More boys,

    11.1% (95% CI; 9.6 – 12.8) were wasted than girls, 9.4% (95% CI; 7.7 - 11.5). These results are higher

    than the previous levels found in the 2012 SMART survey of 9.9 percent [95% CI: 8.8 – 10.8], GAM and

    SAM prevalence of 1.6 percent [95% CI: 1.2 – 2.0] SAM.

    Child obesity in The Gambia does not seem to have a high public health significance. Only a handful of

    LGAs had a few children overweighing or considered as obese as measured by their weight and height

    and compared with the WHO 2006 reference population. Brikama LGA had the highest number of obese

    children 1.2 % (n=2) when compared with other LGA which was positive for overweight indicator.

    Banjul, Kanifing and Mansakonko had an obese prevalence of 0.3%, 0.8 and 0.6% respectively.

  • 3.3 Mortalityrate A proxy indication of mortality was taken retrospectively to provide an idea on the health situation of the

    U5 children and older groups. The mortality assessment was done concurrently with the nutrition survey,

    in which a SMART methodology with two stage cluster sampling methodology was used. The mortality

    questionnaire was administered to a responsible member of that household. All households with and

    without under-five child at the time of the survey were included in the mortality survey. SMART

    methodology1was used to calculate the CDR and U5DR.

    N=4,159 people days at risk (PDAR) were the effective sample size planned for this particular mortality

    survey from a total of two hundred and fifty one (251) clusters. In the end, N=3,781 PDAR from a total of

    two hundred and fifty one (251) clusters were interrogated retrospectively for morality survey

    simultaneously with the anthropometric survey.

    The households were also asked if any member/s of their family either traveled out, came from elsewhere

    to live with them or were born during the past 407 days.

    Out of the total 32,151.5 individuals, 4, 941 under-five children made up the total population for this

    mortality survey. During the recall period (i.e. from 4th of August 2014 to mid-point of survey date i.e.

    September 15th 2015) 301 people joined the sampled households and 1,070 left. During the same period,

    1,026 new babies were born. On the contrary, there were 199 deaths during the same recall period.

    The results show the under-five death rate of 0.85 deaths per 10,000 population per day [95% CI: 0.58 –

    1.23] and a crude death rate of 0.67 deaths per 10,000 population per day (95% CI: 0.56 0.79). These

    results show that the CDR and U5DR increased from 0.17 to 0.67 and 0.24 to 0.85 in the 2012 SMART

    survey and this year period respectively with a 100%s statistical significance when measured by CDC two

  • 3.4Woman’sAnthropometry(15-49yearsofage)Women's nutrition is critical for the life of the individual, her children, community and country. It is also

    important in terms of the cycle of growth failure and the need to break the links between malnourished

    women giving birth to low birth weight babies. The first 1,000 days from conception to the age of 24

    months is a window of opportunity for breaking the lifecycle of malnutrition.

    A total of 9,829 women aged 15-49 years were surveyed in the National Nutrition Survey. All eligible

    women in the household were listed on the household register. If they were not present at the time of data

    collection, they have missing weight, height and MUAC in the dataset. These women with missing data

    were not included in the estimates of malnutrition. These data on missing information are presented in the

    tables.

    Women who were pregnant at the time of data collection were excluded from the analysis of BMI but not

    the analysis of middle upper arm circumference.

    Counts of women by age in years

    Figure 6 Count of women by age in years in the sample, NNS 2015

    Out of the 6,108 women interviewed, there were 5,995 with valid age in years. The age distribution of the

    women in the survey sample is presented above (figure 5). There is evidence of rounding of age in years

    to the nearest zero or five in five year steps. The obvious peaks representing rounding are found at 20,

    25, 30, 35, 40 and 45 years of age. This complicates analysis of malnutrition by age but is not

    considered to affect the estimates of malnutrition in women. The indicators of malnutrition in

    women are not age dependent (low height, BMI and MUAC).

    3.4.1BodyMassIndex(BMI)

    The Body Mass Index (BMI) was calculated from the weights and heights of the non-pregnant women.

    Body Mass Index (BMI) is used to classify underweight, overweight and obesity in adult. It is defined as

    the weight in kilograms divided by the square of the height in meters (kg/m2). BMI are not age dependent

    and same cut-offs are used for both sexes. In developing countries, malnourished individuals with a BMI

    below 18.5 kg/m2 have an increased risk in mortality (Gupta 1999). Using the WHO criteria, it was found

    that 58.2% of non-pregnant women had normal BMI while the rest were underweight, overweight or

    obese. As shown on table 23, nationally 17.7% were underweight but 1.4% were severely underweight,

    24.1% were both overweight and obese.

    Underweight among women was highest in Brikama (25.8%) followed by Kerewan (25.1%) and

    Janjanbureh (21.7%). The least affected LGA was Kanifing (12.6%). The reverse was observed for

    overweight and obesity where Banjul had the highest prevalence at 39.3% followed by Kanifing (33.5%)

    and Mansakonko (24.9%). The lowest prevalence of overweight was in Kuntaur (11.7%) followed by

    Kerewan with 14.2%.

    MUAC is a measure of wasting and has been evaluated in relation to birth outcomes. Low MUAC readings for pregnant mothers are often associated with poor birth outcome although the association has not yet been scientifically established to date. However, as a proxy indicator for low birth weight or poor birth outcome, the current 2015 SMART survey collected MUAC measurement on pregnant mothers.

  • The scatter plot and trend line of BMI over MUAC shows the close relation between the two indicators.

    These indicators do not necessarily measure the same physical traits but the figure shows that women

    with low BMI are also most likely to have low MUAC.

    In the bar chart below, the prevalence and confidence intervals of underweight (low BMI) and acute

    malnutrition (low MUAC) in women are represented by five year age groups. The risk of malnutrition is

    higher in the youngest age group with about 12% having low BMI and 33% low MUAC. The prevalence

    of undernutrition declines over the years and is lowest in the 40-44 age group with about 1% low BMI

    and about 4% low MUAC. The prevalence then rises slightly in the 45-49 age group, mirroring the 2012

    National Nutrition Survey results.

    4.1SampleCharacteristicsThe survey covers 4,017 households and 4,830 U5 children, distributed across the 251 clusters. The total

    boys:girls ratio was 1:0, therefore we can note that there was no gender bias in the selection and each

    gender had an equal chance of being included in the sample.

    4.2MalnutritionThe prevalence of Global Acute Malnutrition of 10.3 percent, though below the emergency threshold of

    15 percent (for WHO malnutrition classification, 2000), is categorized under serious level of malnutrition;

    considering some of the aggravating factors such as high morbidity, mortality and poor food security

    situation with poor key IYCF indicators.

    The recent call from WHO2 which urges countries to intensify serious actions to contain prevalence of

    malnutrition for children (6-59) exceeding 20 percent for stunting, 5 percent for wasting and 10 percent

    for underweight needs to be factored while designing important nutrition-specific and nutrition-sensitive

    programs tailored to the specific needs and priorities of The Gambia. Reducing prevalence of

    underweight children under 5 years of age was an agreed target for MDG 1. Reducing undernutrition will

    ultimately also increase economic growth.

    The current survey and that of the 2012 SMART survey were conducted within the hungry season or lean

    period where most rural households would be busy tending to their farms (land preparation and

    cultivation) and a period for most rural household’s food stocks and reserves being exhausted. This, being

    the rainy season, has huge implications on child care practices due to mother’s busy schedule attending to

    farms and high incidences of diseases such as malaria, diarrhoea and worm infestations that would likely

    compromise children’s wellbeing. Trends in malnutrition as a result are likely to pick up and so do

    admission trends in most health facilities.

    However, to evaluate the statistical significance between the 2015 and 2012 SMART survey findings, a

    CDC calculator for two surveys was used and employed. The results showed that the two surveys which

    were conducted in the same period but in different years yielded no significant statistical difference. We

    can, therefore, say with only 54.7% certainty that the 2015 GAM rate of 10.3% has increased from the

    2012 wasting prevalence of 9.9% or there is not much statistical significance between the two estimates,

    and that the absolute number of malnourished population has stayed almost equal in magnitude.

    From the current survey, it was noted that The Gambia faces multi-faceted malnutrition from stunting,

    wasting, underweight among children under five and an emerging problem with obesity among women

    aged 15-49 years. Child malnutrition (wasting, stunting and underweight) in The Gambia tends to affect

    boys more than girls and this was found to be statistically significant. However, this was the opposite for

    2Global Nutri�on Policy review: What does it take to scale up nutri�on (WHO 2013)

    42

  • wasting prevalence estimated by MUAC and overweight prevalence which tended to affect more girls

    than boys. With MUAC measurement, these findings are consistent to many of the research highlighting

    that MUAC picks up younger children and often times girls than boys. By the same token, the 2012

    SMART survey showed more boys being susceptible to malnutrition than girls, but the actual causes or

    dynamics for the differences in malnutrition estimate between the two genders are beyond the scope of

    this survey analysis. Comparison of malnutrition across the five age bands of children under five was

    more skewed towards the younger age group (6-29 months) as compared to the older age bands (30-59

    months). Ironically, these same age groups were equally affected by multifaceted burden of malnutrition

    such as wasting, stunting and underweight putting an irreversible damage for the current and future lives

    of younger children in the country. The major contributory factors for the consistently high level of

    stunting prevalence in the country points to the high burden of micronutrient deficiencies that are of

    public health concern in the country (vitamin A, zinc, calcium, iodine and anaemia). Vitamin A

    deficiency increases vulnerability to a range of illnesses including diarrhoea, measles, and respiratory

    infections. These are leading causes of mortality among children in low and middle income countries,

    where risk of infection and risk of mortality can be compounded by coexisting under nutrition.

    To understand current the nutritional status of women of reproductive age groups in the country, BMI and

    MUAC measurements were taken for non-pregnant and pregnant women. The survey found that 16.3

    percent of the assessed women were underweight, 1.4 percent severely were underweight and 14.9

    percent were overweight and 9.2 percent were obese. Another observation noted from this survey is that

    the majority of public health problems (malnutrition and mortality) are more p
