Relationship between long-term PM2.5 exposure and myopia prevalence in adults: analysis of the Korea National Health and Nutrition Examination Survey-Air Pollution Linked Data, 2020.

ABSTRACT:

Background

PM2.5 (particulate matter less than 2.5 μm) causes various health problems. Recent studies suggest that long-term exposure to PM2.5 may have a negative impact on vision. This study examined the effects of long-term exposure to concentrations of PM2.5 exceeding Korean standards on myopia prevalence.

Methods

This study was conducted on adults aged 40-69 years. The PM2.5 concentrations were calculated as the 1-5-year moving averages based on the participants' residential areas. The relationships between the PM2.5 levels, categorized by the annual average concentration standard in Korea, and the prevalence of myopia were analyzed using binary logistic regression. The results were evaluated using the 95% confidence interval.

Results

PM2.5 concentrations averaged
