Objective: To investigate the prevalence of myopia and sleep quality among adolescents in Baoshan District of Shanghai, and to further analyze the association between different degree of myopia on sleep quality. Methods: A total of 777 adolescents aged 9-16 years were selected by stratified cluster random method, and ophthalmology examination and Pittsburgh Sleep Quality Index (PSQI) Chinese version scale and related factors questionnaire were conducted. Results: The prevalence rates of myopia and sleep disorders were 68.08% and 13.77% respectively in Baoshan District of Shanghai. With the increase of age and grade, the prevalence of myopia and sleep disorder increased(χ 2=139.58, 114.17；58.00, 56.41, P＜0.01).There were significant differences in sleep disorders among different degree of myopia groups (χ 2=24.57,P<0.01), including sleep time, progressive function and PSQI total score were statistically significant (F=9.65, 7.22, 4.38, P<0.01). Logistic regression analysis showed that moderate to high and high myopia were risk factors for sleep quality of adolescents (β=0.87, 0.95, OR=2.38, 2.59, P<0.05). Conclusion The prevalence of myopia and sleep disorder among adolescents in Baoshan District of Shanghai is high, myopia shows impacts on sleep quality of adolescents at a certain level.
