Abstract
Objective To investigate the reading and writing postures of primary school students in Shanghai, and to explore the associated factors that affect the postures.Methods A total of 2680 primary school students from 7 schools were selected by cluster sampling in one district in Shanghai.Demographic information, reading and writing postures, daily time of near work and visual activities were analyzed.Results 79.6% of the primary school students had unhealthy reading and writing postures.Inappropriate chest-to-desk distance was the most common finding (64.6%), followed by inappropriate distance between eyes and book (42.5%), and distance between finger and nib (29.8%).Students who were in higher grades, allowed intermittent visual rest in long-lasting near distance works, had been on a balanced diet, had good reading environment, and had adequate lighting were less likely to have unhealthy postures.OR values for those factors were 0.683 (0.545~0.857), 0.461 (0.375~0.566), 0.749 (0.608~0.922), 0.326 (0.241~0.442), and 0.300 (0.217~0.416) respectively.Unhealthy postures were more common in students who were myopic, had poor academic performance, had more than 3 hours of homework on school days, and used digital screens over 5 hours during weekends.OR values for these factors were 1.334 (1.017~1.750), 1.670 (1.150~2.426), 1.330 (1.031~1.715), and 1.424 (1.067~1.901).Conclusions Myopia was associated with reading and writing postures.Government, school and family should collaborate to improve near distance work time and habits in order to help students to develop healthy reading and writing postures.关键词
