The consistency of adiposity ranking in the Singaporean Chinese young adult population, using body mass index (BMI) and triceps skinfold (TSF) is investigated; and the need for population-specific standards of adiposity explored. TSF, weight and height were measured in 228 Singaporean Chinese, aged 17-21 years. The correlation coefficient between triceps skinfold and BMI was highly significant: 0.76 for males and 0.64 for females (p < 0.001). However, while mean and median values of BMI were lower than U.S. reference data, corresponding summary measures of TSF were higher. Our data suggest a need for investigating ethnic differences in the various measures of obesity and their health significance; and for developing local standards of obesity.
