| 摘 要： | 目的 分析2007-2015年陕西省成年人体重指数(body mass index，BMI)现状及变化趋势。 方法 利用2007、2010、2013和2015年四次"全国慢性病及其危险因素监测"的数据，采用复杂抽样方法，考虑抽样权重，计算BMI分类(低体重、正常体重、超重和肥胖)率及BMI的不同百分位数(P5，P25，P50，P75，P95)，趋势χ2检验分析四次调查中低体重率、超重和肥胖率的变化趋势，同时以敏感性分析加以验证。 结果 低体重率逐年下降、超重率和肥胖率不断上升，趋势χ2检验有统计学意义(Z=-14.70，P < 0.001)，其中农村居民、18~44岁居民超重率和肥胖率增长最快，BMI年均增长0.176(t=3.00，95%CI:0.055~0.298，P=0.006)个单位，2015年低体重率、超重率和肥胖率与2013年相比无统计学差异(χ2=0.196，P=0.459)。敏感性分析以上趋势不变。 结论 2007-2015年陕西省成年人低体重率不断下降、超重率和肥胖率不断上升，农村居民、18~44岁居民超重率和肥胖率增长最快，值得关注。

| Abstract: | Objective To investigate the trend of BMI among adults in Shaanxi Province from 2007 to 2015. Methods Data was obtained from China Chronic Disease and Risk Factor Surveillance from 2007 to 2015, in which a multistage clustering sampling was adopted to collect a provincially representative sample of adults in Shaanxi Province. BMI percentile(P5, P25, P50, P75, P95) and the prevalence of underweight, overweight and obesity was calculated with weight in each survey. Cochran-Armitage test was used to test trends across survey periods. Changes in BMI across survey years were compared by considering the sampling weight. Results The results of the surveillance indicated that the prevalence of underweight decreased while overweight and obesity increased among adults in Shaanxi province (Z=-14.70, P < 0.001). We observed the highest increase in the prevalence of overweight and obesity among rural residents and residents aged from18 to 44. The mean BMI was estimated to increase 0.176(t=3.00, 95%CI: 0.055-0.298, P=0.006) per year. We found no difference in overweight and obesity (χ2=0.196, P=0.459) between 2013 and 2015. Conclusions We note increases in overweight or obesity and a decrease in underweight among adults in Shaanxi Province. Those living in rural areas and aged from 18 to 44 led the highest increase in overweight and obesity. |
