Background.
Myopia prevalence varies across the country among schoolchildren in China.
Recently, environmental factors have been shown to be important in myopia development and progression.
Given China’s geographical diversity with variable environmental factors, we investigated whether environmental factors could explain the regional variations in myopia in mainland China.
Methods.
We searched PubMed, Web of Science, and Chinese Science Periodical Databases for studies with reports of myopia prevalence in schoolchildren in mainland China from the years 1979 to 2019.
Data on environmental factors (annual sunshine hours, temperature, and population density) were obtained from past records.
A random-effect univariate metaregression analysis was used to investigate the association between the environmental factors and myopia prevalence and to determine the proportion of variation in regional myopia prevalence that can be attributed to each factor.
Results.
Forty-nine eligible studies were identified that included 666,864 schoolchildren aged 6 to 20 years.
The pooled estimate of myopia prevalence was 32.88% (95% confidence interval: 26.69–39.08%).
Univariate metaregression analysis indicated that annual sunshine hours (27.97% of variance), annual temperature (24.66%), and population density (7.06%) significantly contributed to regional myopia prevalence variation (each p<0.05), while seasonal variation in sunshine hours (1.54%, p=0.604) was not a significant predictor of myopia prevalence.
However, only annual sunshine hours was significantly associated with myopia prevalence in the multivariate metaregression model.
Conclusion.
Myopia prevalence in children was higher in regions with low sunshine hours, and annual sunshine hours was significantly associated with regional variation in myopia prevalence in mainland China.
