Outline
Studies have been done to show the effect ofchronic diseases on the quality of life & workproductivity.
• Socioeconomic background• Health status• Workplace environment• Relationship with the employer or co‐workers• Salary satisfaction

The association
(Serxner et al., 2001; Solem et al., 2013; Steiner et al., 2004; Williams et al., 2009)
Workers with chronic diseases have been shown tohave negative impact on productivity level
1. Suffered more work‐loss days per year.2. Reported more absenteeism.3. Having higher rate of presenteeism (working
while sick).4. High sickness absence.
5
Negative Impact
(Boles et al., 2004; Janssens et al., 2012; Tunceli et al., 2005)
• A ratio of a volume measure or dimension of outputto a volume measure or dimension of input use.
• A measure of the efficiency with which anorganization use the resources or inputs to producevaluable outputs such as products or services.
(OECD, 2001)

Productivity

Health & Work Productivity
Good health condition
High work productivity
High performing organization
Good governmental
outcome
(Boles et al., 2004)
Working Together for Health(WHO, 2006)
• To protect & improve thehealth of their communities.
• Each member contributesdifferent skills & performsdifferent functions.
• Empower people abouthealth issues, enforce laws ®ulations and ensureoccupational & environmentalsafety in the community.

Healthy worker
(Serxner et al., 2001)

force.
Important promoters & role models for maintaining a healthy
lifestyle for the general population.
Function in evaluate effectiveness, accessibility &
quality of the health services.

OBJECTIVES
• A cross‐sectional study
• 2 months duration : 1st February 2015 to 31stMarch 2015
• 363 workers from Public Health Division ofKelantan State Health Department in KotaBharu.
• Sampling method : Simple random sampling
13
METHODOLOGY
Inclusion criteria
• Duration of service at least 1year in Kelantan State HealthDepartment
Exclusion criteria
• Pregnant
STUDY CRITERIA
14
Questionnaire• Sociodemographic data
• Health status
• BMI
• Underlying chronic diseases
• Work productivity
• Stanford Presenteeism Scale questionnaire
• Reported days of emergency leaves
• Reported days of sick leaves
15
TOOLS
• Presenteeism• Number of days with unproductive time while at workbecause of health problems.
• The presenteeism was measured using self‐administeredStanford Presenteeism Scale (SPS‐6) questionnairedeveloped by Koopman et al., (2002).
• Absenteeism• Number of days absent from work because of illness ordisease related to health (on leave).
16
OPERATIONAL DEFINITION
• Sickness absence• A person who was absent from work with certified sickleave/MC in 2014.
• Low work productivity described as having one or morecharacteristics :‐1. Absenteeism (missed ≥ 1 day of work) OR2. High presenteeism (high presenteeism score from
Stanford Presenteeism Scale) OR3. High sickness absence (missed ≥ 10 days of work)
• Analysis : Simple & multiple logistic regression analysis

Prevalence of Nutritional Status, Self Reported Cardiovascular Diseases & Smoking Status among Malaysian (NHMS III) versus Public Health Workers in Kota
Bharu
• Male workers have higher odds of low workproductivity when compared to female.
• Long spell of sickness absence among male clerical andsupport staff thus impaired their productivity.
• No relation between work demand and sicknessabsence among female workers.
25
Gender & work productivity
(North et al., 1996)
• Lower grade staff reported to have 2 to 3 times higher oddson having lower work productivity.
• Lower rate of sickness absence in portraying workproductivity among higher officer as it strongly associatedwith high levels of control among them.
• Lower status occupations tend to be characterized by lowcontrol & have fewer ways of coping with high work demands
• They are more likely to be associated with high rates ofsickness absence.
26
Job rank & work productivity
(Bustillos et al. , 2014 )
(North et al., 1996)
Being a worker with certain chronic diseases (e.g DM, hypertension,dyslipidemia) shown to have higher odds of low work productivity.
Workers with DM reported more work‐loss day, increased worklimitation, reported more absenteeism & furthermore failed tomeet the productivity standard.
Hypertensive workers had almost 30% higher risk to experienceabsenteeism.
Employee who self‐identified themselves as havingdyslipidemia showed significant amount lost in work time tosickness absence.
27
Chronic diseases & work productivity
(Buton et al., 1999; Horward and porter, 2014; Tunceli et al., 2005; Williams et al., 2009)
• Chronis diseases leads to poor health andexhaustion among workers.
• These consequently lead to presenteeism.
• Sickness presenteeism is a risk factor for futuresickness absence and furthermore loss inproductivity level.
(Bergstrom et al., 2009)
28
The Consequences
• Public health workers in Kota Bharu have higherprevalence of overweight, diabetes melitus,hypertension and dyslipidemia.
• Male, low rank position workers & workers withcertain chronic diseases are at higher risk oflow work productivity.
29
CONCLUSIONS
• Awareness & wellness program in promotinghealthy lifestyle among healthcare personnelspecifically male & low rank workers.
• Primary prevention, early detection, propertreatment & prevent complications.
• Ensuring optimum clinical management forworkers with chronic disease(s).
• Further disease specific study to explore thepathways on how these specific diseases leadsto low work productivity.
