The aim of the present study was to estimate trends in the prevalence of type 2 diabetes mellitus (T2DM) in adults in China.
A systematic search was conducted for studies of T2DM prevalence in adults in China from 2000 to 2014. Pooled prevalence was calculated by a random-effects model. Subgroup and sensitivity analyses were performed. Chi-squared and Cochran-Mantel-Haenszel tests were used to assess differences among subgroups and pooled prevalence, respectively.
Forty-six studies (data from 1995 to 2014; 1 463 079 adults) were included in the meta-analysis. The overall prevalence of T2DM was 7.9 %. The pooled prevalence overall and by location (urban and rural), gender (male and female), and age category (18-39, 40-59, and ≥60 years) was 4.5 %, 5.1 % and 3.0 %, 4.0 % and 4.2 %, and 1.4 %, 5.0 %, and 10.3 %, respectively, from 1995 to 1999; 6.6 %, 9.3 % and 5.6 %, 7.4 % and 7.5 %, and 1.8 %, 5.9 %, and 12.4 %, respectively, from 2000 to 2004; 10.3 %, 11.8 % and 6.8 %, 10.0 % and 8.6 %, and 2.8 %, 10.3 %, and 20.0 %, respectively, from 2005 to 2009; and 8.3 %, 12.5 % and 7.6 %, 8.6 % and 8.0 %, and 3.5 %, 8.5 %, and 15.3 %, respectively, from 2010 to 2014. The prevalence increased from 5.8 % to 11.6 % with per-capita gross domestic product and differed by diagnostic criteria.
There was a trend of increasing prevalence of T2DM in adults in China from 1995 to 2009, with a decrease in 2010-14 and a greater increase over time in urban versus rural areas, males versus females, and older versus younger adults.
本研究旨在评估中国成年人2型糖尿病（T2DM）患病率的变化趋势。
对2000年至2014年中国成年人T2DM患病率的研究进行系统检索。采用随机效应模型计算合并患病率。进行亚组分析和敏感性分析。分别使用卡方检验和 Cochr an-Mantel-Haenszel检验评估亚组间差异和合并患病率。
46项研究（数据来自1995年至2014年；1463079名成年人）纳入荟萃分析。T2DM的总体患病率为7.9%。1995年至1999年，总体合并患病率以及按地区（城市和农村）、性别（男性和女性）和年龄组（18 - 39岁、40 - 59岁和≥60岁）划分的患病率分别为4.5%、5.1%和3.0%，4.0%和4.2%，以及1.4%、5.0%和10.3%；2000年至2004年分别为6.6%、9.3%和5.6%，7.4%和7.5%，以及1.8%、5.9%和12.4%；2005年至2009年分别为10.3%、11.8%和6.8%，10.0%和8.6%，以及2.8%、10.3%和20.0%；2010年至2014年分别为8.3%、12.5%和7.6%，8.6%和8.0%，以及3.5%、8.5%和15.3%。患病率随人均国内生产总值从5.8%增至11.6%，且因诊断标准而异。
1995年至2009年中国成年人T2DM患病率呈上升趋势，2010 - 2014年有所下降，且城市与农村、男性与女性、老年人与年轻人相比，随时间推移患病率上升幅度更大。
