Hypertension and associated risk factors in some selected rural areas of Bangladesh

Background:Although, Bangladesh has the ninth highest rate of age-standardized rates of deaths due to chronic diseases, mostly due to cardiovascular diseases and diabetes. There is scanty literature on the estimated burden, and the determinants of hypertension in the rural areas of Bangladesh.Methods:This facility based cross-sectional survey was conducted at sub-urban field research clinic from four unions of Araihazar upazilla of Narayangong district, Bangladesh. The analyses were based on 212 male and female respondents of more than 30 years of age. The prevalence of hypertension was the main outcome of interest.  Results:The study found that the prevalence of systolic hypertension among the respondents is 15.6% and that of diastolic pressure is 12.3%. Systolic pressure was found in an increasing manner with the increase of age and BMI. Tendency of increase systolic pressure was observed among those who took extra salt. Significant association was also found between increasing systolic pressure with the heart disease. No significant association was found between increasing systolic pressure with smoking habit, physical activity and vegetable intake and with the development of systemic diseases namely cardiovascular disease (CVD), diabetes mellitus and coronary obstetrics pulmonary disease.Conclusion:Suggestion on regular periodical health check-up especially including blood pressure monitoring and restriction of taking extra salt to all the people of age more than 30 years is recommended.

Blood Lead Levels and Health Problems of Lead Acid Battery Workers in Bangladesh

Introduction. Use of lead acid battery (LAB) in Bangladesh has risen with sharp rise of motor vehicles. As result, manufacture of LAB is increasing. Most of the lead used by these industries comes from recycling of LAB. Workers in LAB industry are at risk of exposure lead and thus development of lead toxicity. Objective. The objective of this study was to measure the blood lead concentration and to assess the magnitude of health problems attributable to lead toxicity among the LAB manufacturing workers. Methods. A cross-sectional study was conducted among the workers of LAB manufacturing industries located in Dhaka city. Result. Mean blood lead level (BLL) among the workers was found to be high. They were found to be suffering from a number of illnesses attributable to lead toxicity. The common illnesses were frequent headache, numbness of the limbs, colic pain, nausea, tremor, and lead line on the gum. High BLL was also found to be related to hypertension and anemia of the workers. Conclusion. High BLL and illnesses attributable to lead toxicity were prevalent amongst workers of the LAB manufacturing industries, and this requires attention especially in terms of occupational hygiene and safety
