AbstractBackground.
Central obesity represents the most common component of metabolic syndrome and confers a substantial cardiometabolic risk. Few studies investigated its time-trend prevalence in Chinese population. This study estimated its prevalence by gender, age, criteria and period.

Methods.
A PRISMA-compliant search was performed in MEDLINE and Embase up to 20 May 2018 for population-based studies reporting the prevalence of central obesity in China. The studies were eligible when they had >500 participants aged ≥18 years. The Metaprop was used to weigh the results of each study by Freeman-Tukey Double Arcsine Transformation. The prevalence and their 95% confidence intervals (CIs) were derived by random-effects models.

Results.
This meta-analysis involved 60 studies with a total of 1,038,902 participants. The overall prevalence of central obesity was 38.9% (95% CI=33.2% to 44.7%). Its prevalence was higher in females (39.7%) than males (24.7%), and in older subjects (45% vs. 14.3% for age ≥ 40 years and <40 years, respectively). Its prevalence was increasing rapidly from 1991-1998 (27.7%), 1999-2007 (32.9%) to 2008-2014 (43.8%), with females having a more significant rise (from 25.8% to 46.2%) than males (from 16.5% to 29.1%). The prevalence varied widely according to different definitions [WHO (26.6%), ATP-III (10.0%), IDF (38.0%), and JIS (55.7%)].

Conclusion.
A significant rise in the prevalence of central obesity was observed over time in China. It is more prevalent and increasing more rapidly in Chinese females. These findings imply that healthcare policies should be formulated to implement strategies in prevention and treatment of central obesity in this group.
