Abstract:

Objective: To evaluate the prevalence of retinopathy of prematurity (ROP) in China by a meta-analysis. Methods: PubMed, Web of Science, Cochrane Library, Embase, CBM, CNKI, Wanfang Data and VIP databases were searched for cross-section studies on retinal disease of preterm infants in China from the date of establishment to December 2020. Two researchers screened the literature, extracted the data, and evaluated the risk of bias in the included studies. The meta-analysis was performed by using Stata12.0 software. Results: A total of 28 studies involving 75 572 patients were included. The results of meta-analysis showed that the prevalence of ROP in Chinese premature infant was 12.6% (95%CI: 11.1% to 14.1%), of which 16% (95%CI: 14% to 18%) for male and 16% (95%CI: 14% to 19%) for female. Grouped by gestational age, 38% (95%CI: 25% to 51%) for ≤30 weeks, 21% (95%CI: 13% to 29%) for 30-32 weeks, and 12% (95%CI: 3% to 20%) for ≥32 weeks. Grouped by body weight, ≤1.5 kg is 32% (95%CI: 28% to 35%), 1.5-2.0 kg is 11% (95%CI: 9% to 14%), ≥2.0 kg is 5% (95%CI: 4% to 7%). Grouped by region, 13% (95%CI: 12% to 14%) in the south, and 13% (95%CI: 12% to 15%) in the north. Subgroup analysis showed that the prevalence was higher in younger age, and the prevalence decreased with the increase of gestational age. The prevalence was the same in the south and the north. Conclusions: The prevalence of ROP in China is 12.6%. There are differences in this rate among preterm infants of different gestational age and body weight.
