[Prevalence and influencing factors of abnormal spinal curvature in primary and secondary school students in Shandong Province in 2020].

In 2020, the prevalence of abnormal spinal curvature among 54 079 students in Shandong Province was 1.54%. The multivariate logistic regression model analysis showed that, compared with those in primary school, economically underdeveloped areas, and non-residential schools, students in middle and high schools, economically average areas, and residential schools had a higher risk of abnormal spinal curvature, with OR (95%CI) values of 2.029 (1.662-2.476), 2.746 (2.208-3.416), 2.237 (1.740-2.875) and 2.057 (1.705-2.483), respectively. Compared with those in economically underdeveloped areas, who were underweight, who had seat adjustments≤1 time per academic year, and who had physical education classes≤1 per week, students in economically developed areas, who were normal weight, overweight, and obese, who had seat adjustments≥2 times per academic year, and who had physical education classes 2-3 or≥4 per week, had a lower risk of abnormal spinal curvature, with OR (95%CI) values of 0.690 (0.521-0.915), 0.722 (0.546-0.955), 0.535 (0.389-0.735), 0.383 (0.274-0.535), 0.835 (0.711-0.980), 0.561 (0.474-0.663) and 0.491 (0.315-0.766), respectively.2020年山东省全国学生常见病和健康影响因素监测与干预项目中，54 079名学生脊柱弯曲异常筛出率为1.54%。多因素logistic回归分析结果显示，与小学、经济较差片区、不住校学生比，初中、高中、经济水平中等、住校的学生脊柱弯曲异常率的风险高，OR（95%CI）值分别为2.029（1.662~2.476）、2.746（2.208~3.416）、2.237（1.740~2.875）和2.057（1.705~2.483）。与经济较差片区、体重消瘦、每学年座位调整≤1次、每周体育课时≤1节的学生比，经济发展好片区、正常体重、超重、肥胖，每学年座位调整频次≥2次、每周体育课时2~3节、每周体育课时≥4节的学生脊柱弯曲异常的风险低，OR（95%CI）值分别为0.690（0.521~0.915）、0.722（0.546~0.955）、0.535（0.389~0.735）、0.383（0.274~0.535）、0.835（0.711~0.980）、0.561（0.474~0.663）和0.491（0.315~0.766）。.
