Abstract
There is insufficient information on the association between overweight/obesity and chronic diseases in developing countries. The objective of this study was to quantify the association between overweight and obesity, measured by BMI, with four chronic diseases in Jamaica. A multistage sampling method was used to recruit a nationally r epresentative sample of 15-74 year olds for the second Jamaica Healthy Lifestyle Survey. Trained personnel measured height, weight and blood pressure and obtained a medical history and fasting capillary blood sample from each participant for the measurement of glucose and cholesterol. Generalised linear models were used to quantify the nature of the association between the chronic diseases and BMI. Analysis accounted for the survey sampling method. A total of 2767 Jamaicans (863 M, 1904F; [Mean Age (+SE)] =36.9(0.05)] years, [Mean BMI(95%CI)] = 26.7(26.1- 27.3) kg/m2)] with complete measures were studied. There was a higher prevalence of obesity in women compared with men (37.7 % F, 12.4 %M; P<0.001). Approximately 25% of Jamaicans had hypertension, 20% were depressed, 12 % had hypercholesterolemia and 8% had diabetes. On bivariate analyses diabetes, high cholesterol and hypertension but not depression was positively associated with increased BMI. After adjusting for age and sex, overweight participants and obese participants were twice as likely to have- 25 -diabetes [(OR 1.80, 95%CI: 1.22-2.62) and (OR 2.21, 95%CI: 1.47-3.32)] respectively or hypertension [OR 1.60, 95%CI: 1.13-2.20) and (OR 2.3, 95% CI: 1.68-3.06)] respectively. The association between BMI and hypercholesterolemia was modified by sex, with overweight and obese men being three times more likely to have hypercholesterolemia [(OR3.04; 95%CI: 1.65-5.61) and (OR 3.68; 95% CI: 1.4-9.66)] while only obese women were more likely to have hypercholesterolemia (OR 1.50; 95%CI: 1.02-2.05). In Jamaica, there is a high prevalence of overweight/obesity, particularly in women, and this is associated with a two to three-fold risk of chronic diseases. The association between increased BMI and chronic diseases parallel that of a developed country.....
