Trajectories and predictors of spherical equivalent among multiethnic school-aged children in Southwest China: a 2.5-year cohort study.

ABSTRACT:

Objective

The development of myopia is subject to individual genetic predisposition and environmental risk exposures. This study aims to investigate the trajectories and predictors of spherical equivalent (SE) among multiethnic school-aged children in Southwest China.

Methods

The school-based cohort study was conducted from October 2020 to March 2023 in Yunnan province, Southwest China. Ocular examinations and questionnaire surveys were administered at each visit. A total of 679 students with complete records from all three visits were included in the final analyses. Group-based trajectory modelling was used to identify SE trajectories. Associations between the trajectory groups and baseline predictors were assessed using multinomial logistic regression.
