AbstractOBJECTIVE: To determine the relationship between percent body fat and body mass index (BMI) in the Chinese population of Hong Kong and to investigate whether the newly proposed lower BMI cut-offs for obesity in the Asia-Pacific Region recommended jointly by the International Association for the Study of Obesity, the International Obesity Task Force and the WHO are appropriate for Hong Kong Chinese. METHODS: A total of 190 female and 140 male healthy subjects were recruited from the community. BMI was calculated as weight/height. Body fat content (%BF) was measured by dual-energy X-ray absorptiometry (DEXA). RESULTS: Comparing %BF measured by DEXA with predicted %BF derived from BMI using a prediction formula developed in Caucasian population showed that the formula significantly under-predicted %BF by 1.1% in males and 3.4% in females. A predicted BMI of 25 and 30kg/m 2 using a Caucasian-based formula corresponds to an actual BMI of 23 and 25 kg/m 2, respectively. On linear regression analysis, 25% BF corresponds to a BMI of 24.6 kg/m 2 in males and a waist circumference of 86 cm; 35% BF corresponds to a BMI of 22.6 kg/m 2 and a waist circumference of 73.5 cm in females. CONCLUSION: Hong Kong Chinese population have a higher %BF for a given BMI which would partly explain why the health risks associated with obesity occur at a lower BMI. Our results would support the recommendations of using lower BMI cut-offs to define obesity in the Asia Region.
