N Am J Med Sci. 2014 Feb;6(2):89-95. doi: 10.4103/1947-2714.127751.


Background: The blood pressure and anthropometric measurements are important for evaluating the health of children, adolescents as well as adults.

Aim: The aim is to study the blood pressure and body dimensions and to find out the prevalence of overweight/obesity and hypertension among adults.

Materials and methods: A cross-sectional study was conducted of all the people belonging to the Punjabi community, residing in Roshanara area and Jaina building in Delhi, for the past 20 years and aged 18-50 years. The men were engaged in transport business and women were mainly housewives.

Results: Mean values of all the measurements, that is, height, weight, upper arm circumference, pulse rate, systolic blood pressure (SBP), and diastolic blood pressure (DBP) were higher among males as compared with females, except skinfold thicknesses. Body mass index (BMI) and fat percentage was found to be higher among females as compared with males. There was a significant positive correlation between BMI, fat percentage, and blood pressure both SBP as well as DBP. Odds ratio showed that overweight/obese subjects were more likely to have hypertension than those with normal BMI.

Conclusion: Prevalence of prehypertension among overweight/obese suggested an early clinical detection of prehypertension and intervention including life style modification, particularly weight management.
