目的研究四川省20～69岁人群BMI时间纵向变化,分析体重超重、肥胖流行现状。方法取2000年和2010年四川省国民体质监测中成年、老年84838人的BMI指数进行分类统计。结果 2010年BMI的均值在全体、男子、女子上高于2000年均值,差异有统计学意义(P﹤0.01);2000年和2010年男子BMI均值高于女子均值,差异有统计学意义(P﹤0.01)。BMI分类统计,男子超重、肥胖比例2010年为33.77%、7.31%,比2000年增长5.24%、2.3%;女子超重、肥胖比例2010年为26.39%、6.82%,比2000年增长0.57%、1.3%。按2010年人口基数推算,样本人群体重超重者达到1746万人,年增长16万人,肥胖者达到409万人,年增长10万人。结论四川地区已进入体重超重和肥胖的突增阶段,应采取切实有力的肥胖防治措施。
Objective To study the longitudinal changes of BMI in 20 ~ 69-year-olds in Sichuan province, and to analyze the prevalence of overweight and obesity. Methods The BMI index of 84838 adults and seniors in Sichuan national constitutional monitoring in 2000 and 2010 were classified. Results The mean of BMI in 2010 was higher than the average of 2000 in men and women (P <0.01). The mean of BMI in men and women in 2010 was higher than that in women (P <0.01), and the difference was statistically significant (P <0.01). According to the statistics of BMI, the proportion of overweight and obese men in 2010 was 33.77% and 7.31% respectively, up 5.24% and 2.3% over 2000. The proportion of overweight and obese women in 2010 was 26.39% and 6.82% respectively, up by 0.57% and 1.3% respectively from 2000 %. According to the population base in 2010, there are 17.46 million overweight people in the sample population, with an annual increase of 160,000 people, 4.09 million obese people and an annual increase of 100,000 people. Conclusion Sichuan has entered the stage of sudden overweight and obesity, and should take effective measures to prevent and treat obesity.
