Impact of Area-Level Socioeconomic and Environmental Measures on Reduced Visual Acuity Among Children and Adolescents.

ABSTRACT:

Purpose

To assess the impacts of area-level socioeconomic and environmental measures on reduced visual acuity (VA).

Methods

This ecological study used the nationally representative cross-sectional data from the Chinese National Survey on Students' Constitution and Health in 2014 (CNSSCH 2014), which included 261,833 participants aged 7 to 22 years randomly selected from 30 mainland provinces in China. Area-level socioeconomic measures assessed included gross domestic product (GDP), population density, density of hospital beds, and nighttime light data measured as the mean digital number (DN) of each region; environmental factors assessed included latitude, annual sunlight duration, and park green space density.
