Abstract
Background: There is a paucity of population based data about the coexistent proportions of risk factors for stroke in South Asians.
Methods: In this cross sectional survey performed in an urban slum, individuals 35 years of age or older were invited for participation through a simple random sample drawn from baseline census data. For each participant a systematic history and examination was performed to confirm the following risk factors: diabetes, hypertension, obesity, tobacco use, coronary artery disease, family history of coronary artery disease and/or stroke. Cerebrovascular events (stroke and TIA) were verified by a vascular neurologist. We report the association of risk factor groups and the presence of contemporaneous cerebrovascular event.
Results: Five hundred and forty-five individuals (49.4% females) participated in the study. One hundred and nineteen (21.8%) individuals had a cerebrovascular event (stroke and /or TIA). Obesity was found to be the predominant risk factor, occurring in 310 individuals (56.9%), followed by total hypertension (284; 52.1%) and tobacco use respectively (213; 39%). Cerebrovascular event increased in percentage with quantitative increase in risk factors. Cerebrovascular event prevalence was 14.3% with one risk factor, 22% with two, 27% with three, 33% with four, and 86% with five risk factors respectively. The combination of 4 risk factors (hypertension, diabetes, obesity and cigarette smoking) conferred the highest odds of having cerebrovascular event at 4.9 (P 0.03).
Conclusion: South Asians in an urban slum often have multiple modifiable risk factors for cerebrovascular event, increasing numbers of risk factors increase the risk of stroke and TIA.
