Abstract：Objective To analyze the associations between diet, physical activity, adverse emotions, and myopia in middle school students, and provide reference for promoting myopia prevention and control in adolescents. Methods Based on the monitoring data of adolescent health risk behaviors from 16 districts of Shanghai in 2021 , relevant information on students’ basic situation, diet, physical activity, adverse emotions, and myopia was obtained. Binary Logistic regression was used to analyze the influencing factors of myopia. Results Data of 17 409 middle school students were included in the analysis. The self-reported prevalence of myopia was 70.18 %. After controlling for gender, grade, study duration, screen usage time, internet addiction, and sleep duration, eating desserts at least once a day and feeling unhappy due to academic pressure or poor scores increased the risk of myopia（OR=1.29, 95% CI: 1.11 -1.49; OR=1.14, 95% CI: 1.03-1.26）. Engaging in physical activity for more than 60 min/d was a protective factor for myopia（OR=0.90, 95% CI: 0.81-0.99）. In addition, prolonged extracurricular study and insufficient sleep (＜7 h/d ) also increased the risk of myopia（OR=1.19, 95 % CI: 1.10-1.29; OR=1.19, 95% CI: 1.10-1.29）. Conclusion It is necessary to strengthen the management of adolescent health behaviors, and in terms of myopia prevention and control, special attention should be paid to those who consume excessive sweets and feel unhappy due to academic pressure or poor scores.
