Introduction: Diabetes Mellitus, obesity and dyslipidaemia are metabolic disorders characterized by similar risk factors, complications and outcomes including stroke, insulin resistance, MI and even death. Studies have indicated that impoverished and low income areas of developing countries are more prone to increasing obesity which when uncontrolled can lead to diabetes mellitus and dyslipidaemia.
Aim: The study was aimed to compare the prevalence of diabetes mellitus, obesity and dyslipidaemia in high and low income groups of North and South Trinidad, to determine factors that contribute to its prevalence and to observe any associations between the three aforementioned diseases.
Materials and Methods: The cross-sectional study was conducted on 200 participants who visited the two major hospitals at south and north Trinidad where the mean differences between fasting glucose, lipid profile, BMI, waist and hip ratio and blood pressure of both diabetic and non-diabetic participants were obtained via questionnaires and then analysed using SPSS.
Results: Residents of south Trinidad showed a higher proportion of persons with diabetes and dyslipidaemia at 68.6% and 52% when compared to 28.6% and 27% respectively for the north population. Those from north Trinidad showed a higher prevalence of obesity at 45.9% with higher income levels. About 17.3% participants smoked or were exposed to cigarettes in north compared to 9.8% of participants whom smoked or were exposed to cigarettes in south. North had 2% of alcohol consumed daily and 3.9% consumed alcohol daily in south. In north, 21.4% of participants were stressed when compared to 18.6% from south.
Conclusion: A significant correlation was established between cholesterol, LDL and triglycerides which lead to the conclusion that obesity is caused by dyslipidaemia. Also, our study concluded that stress and dyslipidaemia are income related.
