“…These rates are similar to results in a study from France and the UK but are lower than in studies from the USA (15%) [18]. The percentage of overweight subjects in this study was lower than in a previous study of Chinese women from Hong Kong [31]. Although BMI can be used as a marker for obesity, WHR is a better indicator of metabolic disorders.…”

Abstract. Metabolic syndrome is a common disorder in Taiwan. For this study 431 subjects were randomly selected from visitors to the Department of Health Management. Blood pressure, blood glucose, lipid, uric acid levels and anthropometric measurements with immunoreactive insulin (IRI) and leptin levels were all correlated. We randomly selected 431 subjects who visited the Department of Health Management. Whole body three-dimensional (3-D) laser scanner scans were employed for the anthropometric measurements. The metabolic index (MI) was designed using anthropometric parameters. Of the 431 subjects, 50% had displayed a body mass index (BMI) equal to or exceeding 25 kg/m 2 . Pearson correlation coefficient and multiple regression analysis revealed that MI constituted another index for correlating metabolic parameters by comparing MI with BMI and waist circumference to hip circumference ratio (WHR). Most data related to metabolic syndrome showed statistically significant differences between high and low IRI groups, comprising uric acid, total cholesterol, fasting plasma glucose, triglyceride, LDL, Chol/HDL ratio, and LDL/HDL ratio. Both IRI and leptin revealed statistical association with BMI, WHR, waist cross section area to hip cross section area ratio (WHAR), and MI in the study. Hypercholesterolemia appeared in 14.6% of the subjects. Elevated low-density lipoprotein (³130 mg/dL) affected 36.9% of the subjects. In conclusion, MI calculated from 3-D body scanner correlated with many important metabolic risk factors and associated with clinical disorders like DM, hyperlipidemia, hyperuricemia and hypertension.

“…We measured body composition in a large population with a relatively accurate method, DEXA, which has been validated in Chinese populations (He et al 1999), thus reducing measurement errors from using surrogate measures such as anthropometry or bioelectrical impedance.…”

“…Several reports have suggested that the BF% derived by DXA may be underestimated compared to the 4C method in Asians. 24,25 For comparison with African Americans, Japanese, Caucasians, and other ethnic groups, the 4C-BF was estimated using Gallagher's equation, 5 and not measured directly by the standard method according to Heymsfield et al 16 However, Asians have higher BF% than Caucasians for any given BMI. As Gallagher's equation was mainly developed from Caucasians, it is reasonable to observe a relatively lower BF% measured by 4C than by DXA in Taiwanese.…”

OBJECTIVES:To compare the different correlations of body mass index (BMI) and percent body fat (BF%) with other ethnic groups and to evaluate the appropriateness of Asia-Pacific redefining obesity criteria in the Taiwanese population. The corresponding BF% to BMI cutoffs of overweight and obesity will also be studied. DESIGN: A cross-sectional epidemiological survey. SUBJECTS: A total of 509 male and 570 female Taiwanese subjects aged !20 y sampled by the systematic stratified clustering sampling method were analyzed. MEASUREMENTS: BMI was obtained by body weight (kg) divided by squared body height (m 2 ). The estimated BMI (BMIe) was deduced from the Caucasian-based four-compartment equation (4C). BF% measured by the methods of dual-energy X-ray absorptiometry (DXA) or Caucasian-based 4C were used and abbreviated as DXA-BF and 4C-BF, respectively. RESULTS: The curvilinear relationship between age and BMI or DXA-BF was established. When compared by age-stratified groups, Taiwanese subjects had a higher BF% (4C-BF) in any given BMI than Caucasians. That is, the level of 4C-BF for BMI!25 kg/m 2 in Taiwanese subjects was similar to BMI!30 kg/m 2 in Caucasians. The BMIe values of 25 and 30 kg/m 2 were nearly equal to the BMIs of 23.6 and 25.3 kg/m 2 in males, and 22.7 and 24.8 kg/m 2 in females, respectively. The 4C-BF of 25% was nearly equal to a BMI of 26.2 kg/m 2 in males, and 35% was equal to a BMI of 24.4 kg/m 2 in females. Consequently, the DXA-BF cutoffs for BMIs of 23 and 25 kg/m 2 were compatible to 23 and 25% in males, and 35 and 38% in females, respectively. CONCLUSION: It was demonstrated that Taiwanese subjects had a relatively lower BMI but a higher BF% than Caucasians. In general, the newly proposed Asia-Pacific BMI cutoffs for overweight (!23 kg/m 2 ) and obesity (!25 kg/m 2 ) may be acceptable to both male and female Taiwanese subjects. The corresponding BF% (DXA-BF) cutoffs for obesity would be 25% in male and 38% in female Taiwanese subjects, respectively.
