A Descriptive Study to Assess Relationship between Body Fat Percentage and Obesity at a Tertiary Level Health Facility

Introduction: The prevalence of obesity is increasing in Indian adults at alarming rate and causing high burden of chronic diseases due to relatively high Body Fat Percentage (BFP) compared to other ethnic groups. There is a dearth of studies on assessment of obesity by using BFP measurement. This study was undertaken to strengththe reliability of BFP in assessment of obesity. Objectives: To find out the relationship between body fat percentage and obesity among adults aged 18-59 years. Method: A total of 228 subjects were included in the study from the in-patients admitted to tertiary care hospitalby systematic random sampling method. In the interview, socio-personal characteristics were collected using pre-tested, semi-structured questionnaire. Anthropometric measurements were conducted to calculate BMI based on Asia-Pacific classification and waist circumference based on International Diabetes Federation guidelines along with body fat percentage was measured using standard guidelines. The t- test, ANOVA and correlation was used to determine the relationship between obesity and BFP. Results: A significant association between Body Fat Percentage (BFP) and obesity measured by Body Mass Index (BMI) and Waist Circumference (WC) was observed across the categories and sex. Positive correlation was observed between BMI and waist circumference (p<0.001), BMI and body fat percentage (P<0.001) and waist circumference and body fat percentage (P<0.001). Conclusions: The study shown significant association and positive correlation between body fat percentage and obesity measured by BMI and waist circumference at lower cut-off among Indian adults indicating BFP is a reliable measure for assessment of obesity.
