【摘要】 目的 探究上海市中小学生弹钢琴与近视的关联，并分析弹钢琴、户外活动时间、课外学习时间与与近视关联的交互作用。方法 于2021年9—11月采取多阶段整群抽样方法，在上海各区分别抽取7所中小学校26 522名学生进行视力检查和问卷调查，采用二分类非条件logistic回归模型分析学生弹钢琴与近视的关联。结果 调查学生中有3 778(14.2%)名学生弹钢琴，22 744(85.8%)名学生不弹钢琴，弹钢琴的学生中近视检出率为77.7%，不弹钢琴的学生近视检出率为76.1%，单因素分析差异有统计学意义（χ~2=4.368,P <0.05），控制性别、父母近视情况等混杂因素后，弹钢琴与近视间关联未发现有统计学意义；以不弹钢琴且户外活动时间≥2 h/d的学生为参照，不弹钢琴且户外活动时间<2 h/d的学生和弹钢琴且户外活动时间<2 h/d的学生近视检出率增加（OR=1.153,95%CI=1.073～1.239;OR=1.165,95%CI=1.038～1.308）；以不弹钢琴且课外学习时间<2 h/d的学生为参照，不弹钢琴且课外学习时间≥2 h/d的学生和弹钢琴且课外学习时间≥2 h/d的学生近视检出率增加（OR=1.212,95%CI=1.119～1.312;OR=1.203,95%CI=1.027～1.411）。结论 未发现学生弹钢琴与近视间存在统计学关联，未来可通过前瞻性研究进一步探索弹钢琴与近视间的关联。更多还原

【Abstract】 Objective To investigate the association between piano playing and myopia prevalence, and to analyze the interactive effect of piano playing and outdoor activity time or out-of-class study time on myopia among primary and secondary school students in Shanghai. Methods Visual acuity tests and a self-administered anonymous questionnaire survey were conducted among 26 522 students recruited using multistage cluster sampling in 7 primary and secondary schools in 7 districts of Shanghai municipality from September to November 2021. An unconditional binary logistic regression model was used to analyze the association between piano playing and myopia prevalence among students.Results Of the students surveyed, 3 778(14.2%) reported playing the piano. The myopia detection rate was 77.7% in students who reported playing the piano and significantly different from that 76.1% in those who did not(χ~2=4.368, P <0.05). After controlling for gender and parental myopia, no statistically significant association was found between piano playing and myopia prevalence. Compared to students who did not play piano and spent 2 hours or more per day in outdoor activities, students who did not play piano and spent less than 2 hours per day in outdoor activities had an increased risk of myopia(odds ratio [OR]=1.153, 95% confidence interval [95%CI]: 1.073-1.239), and students who played piano and spent less than 2 hours per day in outdoor activities also had an increased risk of myopia(OR=1.165,95%CI: 1.038-1.308). Compared to the students who did not play piano and spent less than 2 hours per day studying outside the classroom, the students who did not play piano and spent 2 hours and more per day studying outside the classroom had an increased risk of myopia(OR=1.212, 95%CI: 1.119-1.312) and the students who played piano and spent 2 hours and more per day studying outside the classroom also had an increased risk of myopia(OR=1.203, 95%CI:1.027-1.411). Conclusion This study did not find a statistically significant association between piano playing and myopia prevalence in primary and secondary school students in Shanghai, and further prospective studies may investigate the association between piano playing and myopia in students.更多还原
