目的：来描述身体质量指数中国20-45岁成年人的BMI（单位：kg/m2）分布模式和趋势（1989-2000）。设计：一项关于BMI变化的描述性、基于人群的研究。地点：中国各省（1989年和1997年8次; 2000年为9项），以住户为基础的调查的代表（1989-2000年中国健康与营养调查），采用多阶段随机整群抽样，并辅以国家统计局（SSB）年度家庭消费调查数据。1989年、1997年和2000年，年龄在20至45岁之间的成年人分别为4 527人、4 507人和4 046人。测量：BMI（体重不足：BMI < 18.5 kg/m2，超重：BM >= 25 kg/m2）。结果：与1989年相比，2000年的BMI分布曲线在较高BMI水平（男性和女性）处变平。超重或肥胖的男性比例增加了13.7%，女性增加了7.9%，导致男性的年患病率变化更大。超重和肥胖流行率的增加远远大于体重不足流行率的下降（男子为2.1%;妇女为2.2%）。性别特异性百分位数曲线显示BMI主要在35-45岁的女性和所有年龄组的男性中增加。结论：中国BMI动态显示20-45岁男性的变化率比女性大得多，女性的增加集中在35 - 45岁之间。这些变化预示着在接下来的几十年里，中国其他与饮食相关的非传染性疾病将发生巨大变化。控制BMI的增长趋势，特别是男性，是中国面临的重要公共卫生问题。
Objective: To describe body mass index (BMI, in kg/m(2)) distribution patterns and trends among Chinese adults, aged 20-45 years (1989-2000).Design: A descriptive, population-based study of BMI change.Setting: Chinese provinces (eight in 1989 and 1997; nine in 2000), representative of the household-based surveys (the China Health and Nutrition Survey, 1989-2000) using multistage, random cluster sampling, supplemented with annual household consumption survey data of the State Statistical Bureau (SSB).Subjects: A total of 4527, 4507 and 4046 adults, aged 20-45 years, in 1989, 1997 and 2000, respectively. Measurements: BMI ( underweight: BMI < 18.5 kg/m(2) and overweight: BM >= 25 kg/m(2)). Percentile curves for BMI in 1989 and 2000 were constructed by gender and age using the LMS ( lambda, mu, sigma) method.Results: Compared with 1989, the 2000 BMI distribution curves flattened at higher levels of BMI (men and women). There was a 13.7% increase in the proportion of men and a 7.9% increase of women who were overweight or obese with a resulting greater change in the annualized prevalence rate for men. This increase in the prevalence of overweight and obesity was far greater than the decrease (2.1% for men; 2.2% for women) in that of underweight. Age-gender-specific percentile curves showed BMI increases mainly among women, aged 35-45 years, and among men at all age groups.Conclusions: Chinese BMI dynamics show much greater rates of change among men, aged 20-45 years, than among women, with the increase among women concentrated between ages 35 and 45 years. These changes portend large shifts in other diet-related non-communicable diseases in China over the following decades. Controlling the increasing trends of BMI, especially in men, is an important public health problem facing China.
