Prevalence of ischemic heart disease in a rural population of Bangladesh.

Bangladeshi people, as other South Asians, have high susceptibility to ischemic heart disease (IHD) but population-based data are lacking in Bangladesh. We investigated for IHD burden in a rural population of Bangladesh in 2001. Information was sought on use of medications for IHD and electrocardiogram was done in 447 adults (157 men and 290 women) aged 20 years or older (mean 40 years). Prevalence of IHD defined by presence of pathological Q wave on electrocardiogram or current medication for IHD is 3.4% (95% confidence interval, 1.7% to 5.1%). Prevalence in men (4.6%, 1.3% to 7.9%) was almost twice than in women (2.7%, 0.8% to 4.6%). However, this sex-difference should be cautiously interpreted because of small sample size for men. It appears that IHD is an important problem even in this traditional rural population of Bangladesh.

Non-biochemical risk factors for cardiovascular disease in general clinic-based rural population of Bangladesh.

BACKGROUND: Strategies for preventing premature cardiovascular disease include measures to control its risk factors. To plan such activities, prevalence of these factors must be known. Data regarding risk factor prevalence is limited in Bangladesh and measurement of biochemical factors is not always feasible. The aim of our study is to describe the non-biochemical risk factors in a clinic-based rural population of Bangladesh that would reflect at least a part of the problem in the rural area. METHODS: A cross sectional study was done in a clinic based patient population aged 20 years and older (471 males and 800 females) in a rural community of Bangladesh. A questionnaire on lifestyle including dietary and smoking habit was administered and physical examinations including height, weight, waist circumference, and blood pressure were measured in standardized way. RESULTS: Mean body mass index was 18.5 kg/m2 (standard deviation [SD]: 2.9 kg/m2) in males and 18.7 kg/m2 (SD: 3.3 kg/m2) in females. Mean systolic blood pressure was 120.0 mmHg (SD: 18.5 mmHg) and mean diastolic blood pressure 77.2 mmHg (SD: 9.9 mmHg) in all subjects. The prevalence of hypertension (140+/90+ mmHg and/or on treatment) was 17.8%. Prevalence of tobacco consumption (smoking and chewing) was 43.8% in males and 27.1 in females. Prevalence of abdominal obesity (waist circumference >94 cm in males, >80 cm in females) was 1.6 % and 11.4 % for males and females respectively. Proportion of overweight (BMI 25.0+) was 3.6%. CONCLUSION: Prevention programs and measures should be emphasized for the control of tobacco and hypertension in general, and central obesity in females, as far as rural population of Bangladesh is concerned.
