To analyze the co-morbidity of spinal curvature abnormality and myopia and the relevant factors in primary and middle school students in Guangzhou from 2019 to 2023, so as to provide references for the establishment of the mechanism of Co-morbidity, Shared Etiology, and Shared Prevention of common diseases in students.
From September 2019 to 2023, used stratified random cluster sampling, 4 248, 4 230, 4 266, 25 476, 25 587 primary and middle school students were selected as subjects for spinal curvature abnormality and myopia screening and questionnaire survey. The χ2test was used for comparing the group differences and univariate analysis. The multivariable logistic regression model was used to explore the influencing factors of their co-morbidity.
the co-morbidity rates of spinal curvature abnormality and myopia were 2.96%-6.00% from 2019 to 2023 in primary and middle school students in Guangzhou. The differences in the co-morbidity rates among students of each phases of studying and the difference of the co-morbidity rate in primary and middle school students over the past 5 years were statistically significant (P<0.05). Multivariate logistic regression analysis showed that low BMI junior and senior high school students (OR=1.72, 1.89, 95%CI: 1.11-2.67, 1.47-2.41) were more likely to suffer these two diseases. Primary school students in grades 4 to 6 who had menarche or spermatorrhea (OR=1.77, 95%CI: 1.04-3.02), screening time 2-<3h or≥3h per day (OR=3.06, 2.28, 95%CI: 1.41-6.68, 1.02-5.19), outdoor activities time<2h per day (OR=2.28, 95%CI: 1.22-4.26), junior high school students with low BMI (OR=1.72, 95%CI: 1.11-2.67), whose teacher "never or occasionally" reminded reading and writing posture (OR=1.50, 95%CI: 1.06-2.12), who were not strict with requiring standing and sitting posture themselves (OR=2.51, 1.99, 95%CI: 1.29-4.86, 1.06-3.74), senior high school students with low BMI (OR=1.89, 95%CI: 1.47-2.41) who had activities in the teaching building during recess (OR=1.33, 95%CI: 1.02-1.75), distance from chest to the edge of table "never or occasionally" more than 1 fist away during reading and writing (OR=1.27, 95%CI: 1.05-1.53) had a higher risk of spinal curvature abnormality and myopiaco-morbidity (P<0.05).
The co-morbidity of spinal curvature abnormality and myopia was associated with daytime outdoor exercise and sedentary behavior with bad posture. Early screening and early treatment of spinal curvature abnormality and myopia should be strengthened among adolescent students, especially in urban, female and emaciated students.
