Prevalence of hypertension in an area of urban Varanasi, India and its association with selected demographic factors
Keywords:Demographic factors, Hypertension, Pre hypertension, Spectrum
Background: Non communicable diseases (NCDs) are the leading cause of death in WHO South East Asian Region and the rising trend is attributed to a variety of factors viz smoking, sedentary life style etc. Hypertension is considered as the principle risk factor for heart attack and stroke. The main objective was to assess the prevalence and spectrum of hypertension and its association with selected demographic factors in an area of urban Varanasi.
Methods: This cross- sectional community based study was undertaken in a selected area of urban Varanasi. The study sample comprised of subjects 25 years and above. After obtaining ethical clearance and taking consent from study subjects, they were specifically interviewed for selected demographic characteristics using pre designed and pre tested proforma. Their blood pressure was measured using electronic BP machine following standard technique. The data was entered in personal computer and analyzed with SPSS.
Results: Out of 611 subjects, 314 (51.4%) subjects were male and 297 (48.6%) were female. 51.7% and 20.0% subjects were categorized as normal and pre hypertensive respectively. As much as 19.6% and 8.7% subjects were in stage 1 and stage 2 hypertension. Presence of hypertension increased significantly (p<0.001) with advancing age.
Conclusions: Hypertension is a significant problem in study subjects. Nearly one fifth of the subjects were in pre hypertensive stage. Preventive strategies should be directed to them for positive impact.
