Factors Associated with the Spectacle Wear Compliance among Primary School Students with Refractive Error in Rural China

摘要

Purpose To study the factors determining spectacle-wear compliance and reasons for non-wear among students in rural China. Methods This study was based on a spectacle intervention trial among 162 schools in rural China. Students with refractive errors were randomly assigned to either a free or voucher group to receive spectacles at baseline. Spectacle-wear compliance was assessed through an unannounced follow-up 7 months after spectacles were distributed. Students not wearing spectacles were also asked their reasons for non-wear. The collected data underwent descriptive, bivariate, and logistic regression analyses. Results A total of 1904 students received spectacles at baseline, 1826 (95.9%) of whom were present at the 7-month follow-up. Among those students, 41.7% wore their spectacles. There was no significant difference in compliance rates between the free and voucher groups. Predictors of wearing spectacles at follow-up included older age (Odds ratio = 1.56, 95% CI: 1.12-2.19), the severity of refractive error (3.68, 2.23-6.07), wearing spectacles before baseline (3.91, 2.53-6.04) and having friends who wore spectacles (1.87, 1.32-2.63). When students could see the blackboard from their seats (0.68, 0.51-0.89) and thought that wearing spectacles was bad looking (0.76, 0.57-1.00), they were reluctant to wear spectacles. The two main reasons for non-wear were the widespread perception that wearing spectacles would weaken eyesight (32.8%) and the inconvenience of wearing spectacles during activities (23.6%). Conclusions The main reason that accounts for the low compliance of spectacle wear was misconceptions around spectacle. School-based spectacle programs should consider enhancing the compliance rates to maximize the benefits of spectacle wear.
