BACKGROUND: Diabetes represents a significant public health challenge in China. This comprehensive meta-analysis systematically investigated temporal patterns in diabetes prevalence and evaluated key modifiable risk factors among Chinese adults over a 20-year period (2000–2020). METHODS: We conducted a systematic search across six major electronic databases to identify population-based epidemiological studies reporting diabetes prevalence and/or associated modifiable risk factors. Eligible studies underwent rigorous quality assessment. Random-effects meta-analyses were performed to calculate pooled prevalence estimates with 95% confidence intervals. Subgroup analyses examined variations across critical demographic and geographic strata, including sex, age groups, urban-rural residence, geographic region, and body mass index (BMI) categories. RESULTS: A total of 109 studies involving over 1.74 million adults were included. The results showed that the overall combined prevalence of diabetes among Chinese adults was 9.51% (95% confidence interval: 8.73% -10.30%), corrected for standardization to 8.68% (95% CI: 7.80% - 9.57%) from 2000 to 2020. Prevalence was higher in males (10.19%), urban/suburban residents (10.44%), older adults (≥ 60 years: 19.27%), and regions like Chongqing Municipality (15.74%), Sichuan province (15.40%), and Henan province (15.16%). Higher BMI was associated with increased prevalence (18.84 %, BMI ≥ 28 kg/m2). Key modifiable risk factors included nonalcoh...
