ABSTRACT
Objective To evaluate the prevalence and trend of diabetes mellitus among Chinese adults during the past thirty years.Methods Papers,published before October 1,2017 and related to the prevalence of diabetes mellitus among Chinese adults,were searched through PubMed,China Knowledge Resource Integrated Database,Wanfang Digital Database and VIP Citation Databases.Stata 13.0 software was used to estimate the prevalence of diabetes mellitus,with pooled prevalence calculated based on random effects.Subgroup analysis was conducted based on time,sex,areas and body mass index groups of investigation.Continuous fractional polynomial regression model on the midpoint of each survey period,weighted by the number of participants in each study,was used to estimate and illustrate the trends of prevalence of diabetes over the years.Results In total,15 studies were included and two of them were excluded in the primary analysis with the age limitation of participants as ≥40 years old,for recruitment.The average prevalence of diabetes among Chinese adults was 6.3％ (95％CI:4.6％-8.0％),during the past thirty years.The pooled prevalence appeared higher in urban than in rural areas and higher in men than in women.Between 1980 and 2013,the increase of Chinese diabetes prevalence did not follow the linear trend.Before 2000,the average prevalence showed as 3.5％ (95％CI:2.0％-4.9％),with an annual increase rate as 0.17％.Since 2000,the average annual prevalence of diabetes mellitus had appeared around 8.0％ (95％CI:6.0％-10.1％),with an annual growth rate of 0.72％ (95％CI:0.34％-1.10％).Conclusion The prevalence of diabetes in Chinese adults had been rapidly increasing since the year 2000,indicating that efforts should be strengthened for diabetes prevention,in China.

ABSTRACT
Objective@#To discuss the main causes and risk factors of disability and death among current Chinese adolescents.@*Methods@#Subnational data of China from Global Burden of Disease Study 2015 (GBD 2015) was used to rank the causes and risk factors leading to death and disability adjusted life years (DALY) in Chinese adolescents aged between 10 and 19 years old, and thereby to analyze the main cauese and risk factors of death and DALY among Chinese adolescents in different genders.@*Results@#In 2015, among Chinese adolescents aged 10-19 years old, the total DALY was 13 million 490 thousand years, and the total number of deaths was 63 258 cases. The top 3 causes of DALY were skin and subcutaneous diseases, iron-deficiency anemia and road injuries, resulting in DALY (constituent ratio) of 1 411 (10.5%), 1 094 (8.1%) and 1 029 (7.6%) thousand years respectively. The top 3 causes of death were road injuries, drowning and leukemia, causing 13 881 (21.9%), 9 895 (15.6%) and 4 620 (7.3%) deaths (constituent ratio) respectively. The top 3 risk factors of DALY were iron deficiency, alcohol use and drug use, causing 1 094 (8.1%), 487 (3.6%) and 220 thousand years (1.6%) DALY (constituent ratio) respectively. The top 3 risk factors of death were alcohol use, occupational injuries and drug use, causing 5 957 (9.4%), 1 523 (2.4%) and 810 (1.3%) deaths respectively.@*Conclusion@#Unintentional injury was the top cause of DALY and death in Chinese adolescents, followed by skin and subcutaneous diseases and iron-deficiency anemia. Iron deficiency and alcohol use were the top two risk factors of DALY and death.
