The study intends to find out the relationship of blood pressure and obesity among adult male of North 24 Parganas, West Bengal. A cross sectional study has been carried out among 232 male (aged 18 to 60 years) in four villages of block Habra I and II of North 24 Parganas, West Bengal. Two anthropometric measurements viz. height and weight were taken; BMI was calculated. Systolic and diastolic blood pressures were taken and MAP was calculated. There is a significant positive correlation (r= 0.404) between Body Mass Index and Mean Arterial Pressure. With the increasing of BMI status there is a significant increase in both systolic blood pressure and diastolic blood pressure (r= 0.389 and 0.362 respectively). There is a significant difference between Mean Arterial Pressure of obese and non-obese persons (t=3.4005). The study suggests that, the effect of obesity is present on blood pressure, in adult male of the studied area.
