Abstract

Objective: To compare body mass index (BMI), waist circumference (WC), and body fat percentage (%BF), as index of overweight and obesity in young adults. We also intended to find an association between lifestyle behaviours and obesity. Methods: A cross-sectional study was conducted at Fatima Jinnah Dental College, Karachi, during 2007 to 2008, with 192 first year dental students, (18-21years) of high socioeconomic class. All were questioned regarding lifestyle behaviours. Overweight and obesity were estimated by measuring %BF, BMI, and WC. For %BF, skinfold thickness was measured using skinfold calipers. BMI > 23.0-24.9 kg/m2 was taken as overweight and > 25.0 kg/m2 as obese (Asians criteria proposed by Western Pacific Regional Office of World Health Organization). WC using Asian cutoff values for overweight and obesity were: males > 78cm and > 90cm; females > 72cm and > 80cm, respectively. Body fat percentage used to define overweight and obesity was: males 22.1-27.0 and >27.1; females 27.1-32.0 and >32.1, respectively. Pearson's correlation was done between the BMI, WC and %BF with statistical significance taken at P
