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 <0.01. Results: BMI (Expressed as mean±SD) in males and females was 23.82±3.88 and 20.98±4.12 respectively. WC was 83.63±10.20cm in males and 70.22±9.36cm in females. %BF was 22.32±6.27 in males and 28.73±6.65 in females, with an overall 60.8% females and 44.4% males found to be overweight or obese. Obesity was underpredicted by BMI when compared to skinfold calipers method. The obese were seen to skip breakfast more often [odds ratio (OR):2.39], take frequent snacks (OR:1.58), watch television more (OR:1.58), and were physically less active than their non-obese counterparts. Conclusion: Body fat percentage using skinfold caliper is a reliable index of obesity. Lack of sleep and skipping of breakfast, are prominent promoters of obesity, in addition to other lifestyle behaviours.
