Prevalence of and Risk Factors for Dry Eye Symptom in Mainland China: A Systematic Review and Meta-Analysis

الملخص EN

Purpose.

To evaluate the pooled prevalence rate and risk factors of dry eye symptoms (DES) in mainland China.

Methods.

All the published population-based studies investigating the prevalence of DES in China were searched and evaluated against inclusion criteria.

A systematic review and meta-analysis were performed.

Results.

Twelve out of the 119 identified studies were included in the meta-analysis.

The pooled prevalence of DES in China was 17.0%.

Female individuals, subjects living in the Northern and Western China, and over 60 years of age had significantly higher prevalent rates (21.6%, 17.9%, 31.3%, and 34.4%, resp.) compared with their counterparts.

Patients with diabetes were also found to be more vulnerable to DES.

Conclusions.

The pooled prevalence rate of DES in mainland China was lower than that in other Asian regions and countries.

A remarkable discrepancy in the prevalence in different geographic regions was noted.

Aging, female gender, and diabetes were found to be risk factors for DES in China.
