The aim of this cross-sectional observation study was to assess thoroughly the body mass index (BMI) profile in Hong Kong Chinese and report all categories of BMI cutoff points as suggested by the World Health Organization (WHO). A cohort of 17,242 subjects (4822 men and 12420 women) aged 15 or above from the community of Hong Kong presenting themselves voluntarily from April 1996 to August 1997 for primary health assessment at the Three Health Centers of the United Christian Nethersole Community Health Service (UCNCHS). The mean age (+/- SD) was 51.0 +/- 16.2 years (range 15-96 years, median 49.6 years). The mean BMI of the 17,242 subjects was 23.5 +/- 3.3 kg/m2 in men and 23.0 +/- 3.7 kg/m2 in women. The BMI peaked at age 30 to 50 years in men and 50 to 70 years in women. The age-standardized prevalence of BMI > or = 30 kg/m2 or > or = 25 kg/m2 in Hong Kong Chinese was 3.0% in men and 3.2% in women, and 29.1% in men and 21.3% in women, respectively. For underweight, 35.9% and 27.8% of women and 27.5% and 10.3% of men aged 15-20 and 20-30 years, respectively, had BMI < 18.5 kg/m2. In conclusion, a significant proportion of Hong Kong Chinese had a BMI > or = 25 kg/m2. Among Hong Kong Chinese aged < 30 years, the prevalence of underweight was also high.
这项横断面观察研究的目的是全面评估香港华人的体重指数（BMI）概况，并报告世界卫生组织（WHO）建议的所有BMI切点类别。1996年4月至1997年8月期间，香港社区的17242名15岁及以上受试者（4822名男性和12420名女性）自愿前往联合基督教女青年会社区健康服务中心（UCNCHS）的三个健康中心进行初级健康评估。平均年龄（±标准差）为51.0±16.2岁（范围15 - 96岁，中位数49.6岁）。17242名受试者的平均BMI男性为23.5±3.3kg/m²，女性为23.0±3.7kg/m²。BMI在男性30至50岁、女性50至70岁时达到峰值。香港华人中BMI≥30kg/m²或≥25kg/m²的年龄标准化患病率男性分别为3.0%和29.1%，女性分别为3.2%和21.3%。对于体重过轻，15 - 20岁和20 - 30岁的女性中分别有35.9%和27.8%、男性中分别有27.5%和10.3%的BMI<18.5kg/m²。总之，相当一部分香港华人的BMI≥25kg/m²。在30岁以下的香港华人中，体重过轻的患病率也很高。
