Abstract:
Objective:To examine the effect of lifestyle behaviors on myopia among primary and middle school students in Yinzhou District, Ningbo City using latent class analysis, so as to provide insights into prevention of myopia among primary and middle school students.
Methods:A total of 1 547 students were sampled from primary and middle schools in Yinzhou District using a stratified cluster sampling method. Myopia-associated lifestyle behaviors were collected using questionnaires, and visual acuity was tested. Myopia-associated lifestyle behaviors were subjected to latent class analysis among primary and middle school students, and the association between lifestyle behaviors and risk of myopia was examined using a logistic regression model.
Results:A total of 1 547 questionnaires were allocated, and 1 494 valid questionnaires were recovered, with an effective recovery rate of 96.57%. There were 247 primary school students (16.53%), 452 junior high school students (30.25%), 532 senior high school students (35.61%) and 263 vocational high school students (17.60%), and 773 men (51.74%) and 721 women (48.26%). Latent class analysis showed that students' lifestyle behaviors were classified into three groups, including the healthy behavior group (37.68%), reading and writing fatigue group (42.64%), and video fatigue and poor diet group (19.68%), with myopia prevalence of 79.22%, 88.38% and 86.73%, respectively. Moderate myopia was predominant in the reading and writing fatigue group and video fatigue and poor diet group, and low myopia was predominant in the healthy behavior group. A higher risk of myopia was found in the reading and writing fatigue group (OR=1.996, 95%CI: 1.454-2.739) and video fatigue and poor diet group (OR=1.715, 95%CI: 1.157-2.543) than in the healthy behavior group.
Conclusions:Long reading and writing duration, insufficient exercise and sleep, long video watching duration, and high intake frequency of sugary drinks and fried foods may increase the risk of myopia in primary and middle school students in Yinzhou District. Targeted myopia interventions are required tailored to different categories of lifestyle behaviors.
