ObjectivesTo systematically review the prevalence of rosacea in China.MethodsPubMed, The Cochrane Library, EMbase, CNKI, WanFang Data and VIP databases were electronically searched to collect literature of the prevalence of rosacea in China from inception to September 5th, 2018. Two reviewers independently screened literature, extracted data and then meta-analysis was performed by using Stata 12.0 software.ResultsA total of 54 studies were included. The pooled prevalence of rosacea from 44 population-based or community-based studies was 0.27% (95%CI 0.22 to 0.32) and from 10 hospital-based studies was 1.47% (95%CI 1.08 to 1.86). Based on population-based or community-based studies, the highest prevalence was in the early 1980s (2.19%), followed by a gradual decline, to the lowest (0.17%) in the early 1990s, after that the prevalence increased to 1.24% till 2015. Based on hospital-based studies, the prevalence had a maximum of 4.64% in the past decade. The Northwest China and North China had higher prevalence of rosacea (population-based or community-based studies: 1.24% in Northwest China, 1.1% in North China; hospital-based studies: 6.03% in Northwest China, 2.83% in North China). The prevalence in East China and South China was relatively low (population-based or community-based studies: 0.02% in East China and 0.32% in South China; Hospital-based studies: 0.28% in South China). The prevalence of rosacea in female (0.36%) was higher than that of male (0.19%) in population-based or community-based studies.ConclusionsIn China, the pooled prevalence of rosacea is 0.27% in population-based or community-based studies and 1.47% in hospital-based studies. Rosacea is common in North China and Northwest China. Female has higher prevalence than male.
