Association between building density and screening myopia in children and adolescents: a 5-year longitudinal study from China.

ABSTRACT:

Background

This study explored the relationship between school-level built environment factors (building density and height) and myopia prevalence.

Methods

In all 16 districts of Shanghai, students from public schools and kindergartens underwent visual acuity testing and non-cycloplegic refraction between 2019 and 2023. Building density and height within 500-metre and 1,000-metre buffers around the schools were obtained using GIS (Geographic Information System)-based spatial and network analyses from the Tianditu database. Demographic and behavioural covariates, such as age, gender, outdoor activity time and near-work time, were collected through questionnaires. Logistic mixed-effect models were used to analyse the association between the building environment and myopia, adj
