Sociodemographic factors and the risk of developing cardiovascular disease in Bangladesh.

Abstract

Sociodemographic determinants of predicted 10-year risk for stroke or myocardial infarction are vital to identify patients who are at increased risk. Although some risk factors of predicted cardiovascular disease (CVD) risk are documented, further exploration is necessary considering various socioeconomic and demographic factors. To examine risk factors for stroke or myocardial infarction according to 10-year prediction, among hypertensive patients and by sociodemographic risk differences, using a nationally representative survey. Data were obtained from the 2011 Bangladesh Demographic Health Survey and analyzed in March and July 2014. The analyses were based on responses from 1,620 hypertensive individuals. WHO guidelines for predicting 10-year risk of stroke or myocardial infarction were applied to categorize risk of CVD into low, medium, or high strata. A total of 21.8% of hypertensive adults were at high risk for CVD. An adjusted ordinal logistic regression model showed that a female- versus male-headed household (AOR=1.85); an urban versus rural residence (AOR=1.32); being overweight/obese versus underweight (AOR=1.80); and being aged 55-69 years (AOR=1.95) or ≥70 years (AOR=2.87) versus 35-54 years were significantly associated with higher CVD risk. A regional difference in distribution of CVD risk strata was observed. Living in a female-headed household, having an urban residence, being overweight/obese, old age, and regional variations are factors associated with higher risk of CVD among hypertensive patients.
