For present cross sectional study 253 Bidi workers of 18-75 years of age were selected randomly from 119 household of Bidi workers of district Sagar of M.P. Out of 253 samples 114 were male and 139 were female. A pre tested, semi structure schedule was used for collecting information by physiological and anthropometric measurement. Before taking measurements the instruments were standardized. Technical error of measurement (TEM) was calculated to remove the error. After collecting data, indices were computed and statistical analysis was done by using SPSS 16.0 and MS excel software. Linear bivariate and multivariate regression analysis was done using Systolic and Diastolic blood pressure as dependent variable. The main objective of present study was to find out the extent and determinants of Blood pressure among Bidi worker of Sagar district of M.P. On the basis of systolic blood pressure majority (66.18%) of bidi worker were found as pre hypertensive out of which (39.1%) were male and (33.8%) were female. Only 2.3% of Bidi worker were suffering with hypertensive emergency crises. The highest mean systolic blood pressure (135.0±16.1mmHg) was found among male of 30-34 years of age; whereas among female the highest mean systolic blood pressure (138.6±23.61mmHg) was found among female of above 50+ years of age. According to age wise diastolic blood pressure the mean diastolic blood pressure of male was higher than female in all age group except 40-45 year of age. It can be concluded that majority of Bidi worker (50-60%) were pre hypertensive. A small proportion (2.3%-3.2%) was suffering with hypertensive emergency. As per bivariate and multivariate regression analysis the blood pressure is determined by age, body fat, BMI, body weight, height and BMR.
