Abstract:Essential hypertension accounts for 90% of all cases of hypertension. Though it is a one of major risk factors for cardiovascular diseases, it is a condition with its own risk factors. Overall prevalence of hypertension is increasing over the years in India (from 3.57% in 1977 to 20-30% after 1995). Considering the public health importance of ‘Essential Hypertension’ the present study was conducted. The objective was to study role of certain risk factors in essential hypertension. A case control study was conducted in rural township of Tasgaon; in Sangli district of Maharashtra during 2001-2002, to study role of certain modifiable risk factors in essential hypertension in 21-60 years age group. 165 cases of essential hypertension were selected by systematic random sampling from two private hospitals & O.P.D. of RHTC, Tasgaon and 330, age & sex matched controls were selected in the ratio of 1:2. A significant association was found between essential hypertension and various risk factors including smoking, its frequency and duration, alcoholic status, leisure time physical inactivity, restless sleep, BMI, mental stress, mixed diet and salt intake. Smoking of more than 10 cigarettes or bidi had 3.23 times risk of developing hypertension than smoking up to 10 cigarettes or bidi.
