Estimation of the mortality caused by diabetes mellitus in Panama and its relationship to gender and cardiovascular risk factors
Jorge Motta1, Carlos Gordón1, Beatriz Gómez1, Eva Castillo1, Víctor Herrera Ballesteros1
INTRODUCTION
Although diabetes mellitus is among the top 5 leading causes of death in the Republic of Panama, little information is available that relate the mortality from this disease to biological risk factors such as age, gender, obesity, hypertension, hyper- cholesterolemia, and socioeconomic factors.
OBJECTIVES
To characterize the status of diabetes mellitus mortality in Panama and its relationship with risk factors present in the population.
MATERIALS AND METHODS
The methodology involved compilation and anlaysis of data from the National Survey of Quality of Life and Health, Living Standards Survey obtained in a sample of 25,748 individuals, data from the National Population Census of 2000 and 2010 and the National Registries of mortality from all causes for the years 2001 to 2009. We generated indicators of crude, adjusted and specific rates of mortality from diabetes and compared these rates with the presence of risk factors such as obesity, hypertension and elevated cholesterol at provincial, district and county levels. Regression coefficients were derived from multivariate analysis of biologic and socioeconomic factors known to be related to the risk of dying from diabetes.
RESULTS
After compiling and analizing the data for mortality from diabetes mellitus for the years 2001 – 2009, for biologic risk factors and socioeconomic factors from different regions of Panama and inserting these in a geographic information system, we find that women have a higher mortality from diabetes than men in Panama. Women also have a higher prevalence of obesity and also a higher prevalence of self-reported hypertension and of elevated cholesterol. Certain provinces like Los Santos and Colon have higher crude mortality rate than the rest of the country. The biological risks factors found to be most related to diabetes mortality were obesity, hypertension, hyperlipidemia and being 55 years of age or older. For the socio-economic analysis the factors found to be most related to diabetes mortality were the following: having less than 6 years of schooling and being unemployed.
CONCLUSIONS
During the years 2001 - 2009, women sufered a higher mortality from diabetes than men. Women had a higher prevalence of obesity than men. Mortality was higher in both sexes after reaching 45 or more years of age. Some provinces exhibited a higher mortality rates from diabetes probably because they had a greater number of older inhabitants, and a higher prevalence of obesity and hypertension. Unemployement and less education appear also to be related to mortality from diabetes.

The Compound Index was derived from a factorial analysis of the following variables: Ethnicity (indigenous and afro) population, monthly income less thant 100 U.S., unemployed status, gender, % of the population with less than 6 years of education and % of the population with an age greater or equal to 65 years. The socioeconomic factors most related to diabetes mortality in Panama were: % of the population with less than 6 years of education, % of unemployed population and the % of the population aged over 65 years. Additionally, a multiple linear regression analysis yielded the following coefficients for these variables, -0.86 (-4.48) 0.52 (4.72) and 1.18 (10.04) respectively. Values in parentheses are the t statistics - student. The coefficient r2 was 0.283 and the correlation 0.532. The dependent variable was the crude mortality rate for diabetes mellitus.

Analysis of biological risk factors related to mortality from diabetes mellitus by district. Panama. 2007.
The Compound Index was derived from a factorial analysis. The four biological risks factors that were found to be most related to diabetes mortality were obesity, hypertension, hyperlipidemia and having an age of 55 years or more. Additional analysis included four separate regressions for each of the explanatory variables and the coefficients obtained were the following: obesity 0.932 (6.048, 0.346), hypertension 1.136 (5.985, 0.338), hyperlipidemia 0.599 (4.485, 0.234),) and age greater or equal to 55 years of age 1.078 (3.273, 0.133). Values in parentheses represent the student-t and the r2.
