Skinfold thickness, body fat percentage and body mass index in obese and non-obese Indian boys

Childhood obesity is presently increasing worldwide and has created enormous concern for researchers working in the field of obesity related diseases with special interest in child health and development. Selected anthropometric measurements including stature, body mass, and skinfolds are globally accepted sensitive indicators of growth patterns and health status of a child. The present study was therefore aimed not only at evaluating the body mass index (BMI), skinfolds, body fat percentage (%fat) in obese school going boys of West Bengal, India, but also aimed to compare these data with their non-obese counterparts. Ten to sixteen year old obese boys (N = 158) were separated from their non-obese counterparts using the age-wise international cut-off points of BMI. Skinfolds were measured using skinfold calipers, BMI and %fat were calculated from standard equations. Body mass, BMI, skinfolds and %fat were significantly (P <0.001) higher for the sample of obese boys when compared to their non-obese counterparts. The obese group also showed progressive age-wise increments in all recorded anthropometric parameters. Stature (cm) showed no significant inter-group variation except in the 10 year age group (P <0.001). All data for the non-obese group were comparable with other national and international studies, but those collected for the obese group could not feasibly be compared because the availability of data on obese children is limited. Current data and prediction equations will not only serve as a reference standard, but also be of vital clinical importance in order to identify or categorize obese boys, and to take preventative steps to minimise serious health problems that appear during the later part of life.
