Overweight Japanese with body mass indexes of 23.0-24.9 have higher risks for XXXX : a comparison of Japanese and Mongolians.

OBJECTIVE: The degree of @entity28 of Asians is less than that of Caucasians. It has been suggested that Japanese, categorized as having normal weight (BMI<25.0), as defined by WHO (2000), have a tendency toward increased incidences of @entity2299 and @entity6 . Our objective was to analyze parameters constituting @entity28 in overweight Japanese and Mongolians with a body mass index (BMI) of 23.0-24.9, and to assess the suitability for Asians of the Regional Office for Western Pacific Region of WHO criteria pertaining to @entity28 (WPRO criteria, 2000). DESIGN: Cross-sectional study in a workplace setting. SUBJECTS: A total of 386 Japanese @entity1 and 363 Japanese @entity1 , and 102 Mongolian @entity1 and 155 Mongolian @entity1 . MEASUREMENTS: Anthropometric measurements (weight, height, waist circumference, hip circumference and blood pressure) and metabolic measurements (plasma levels of total @entity165 , HDL @entity165 , @entity412 , @entity413 and insulin). RESULTS: Graded increases in BMI of Japanese and Mongolians were positively associated with body fat percent, waist circumference, hip circumference and waist/hip ratio. The Japanese were categorized as 22% overweight, 22% obese I, 3% obese II; the Mongolians rated as 18% overweight, 34% obese I, 19% obese II, based on the WPRO BMI criteria. The Mongolians had a higher prevalence of @entity28 and a higher body fat percent, but a lesser gradation of @entity2299 , than did the BMI-matched Japanese groups. Overweight Japanese (BMI 23.0-24.9), in comparison to normal Japanese (BMI 18.5-22.9), had significant differences in systolic blood pressure, HDL- @entity165 and @entity412 in @entity1 , and in systolic and diastolic blood pressure, HDL- @entity165 , @entity412 , insulin and Homoeostasis model assessment-insulin resistance in @entity1 . In contrast, the Mongolians showed no significant differences in metabolic parameters between overweight and normal subjects, except for diastolic blood pressure. CONCLUSION: Since the relationship between abdominal fat mass and BMI is ethnic-specific, a universal BMI cutoff point is inappropriate for Asian populations such as the Japanese and Mongolians. The present investigation suggests that, while the WPRO criteria are suitable for Japanese, the WHO criteria are more appropriate for Mongolians.
