To investigate the prevalence and associated factors of spinal curvature abnormalities among primary and secondary school students in the Guangxi Zhuang Autonomous Region, so as to provide a scientific basis for the prevention and control of such abnormalities.
From September to November 2023, adopting a stratified cluster random sampling method, spinal curvature screenings and questionnaire surveys were conducted among 168 931 students from grade 4 of primary school to grade 12 of high school in 111 districts and counties across 14 cities in Guangxi. Chi-square tests and binary Logistic regression analysis were used to analyze influencing factors of spinal curvature abnormalities.
In 2023, the detection rate of poor posture among students above grade 4 in Guangxi was 4.24%, and the detection rate of spinal curvature abnormalities was 2.13%. The detection rate was higher among urban students (2.84%) than rural students (1.66%), boarding students (2.61%) than non-boarding students (1.60%), and high school students (3.16%) than junior high (2.45%) and primary school students (1.15%), and the differences were statistically significant (χ2=269.85, 221.44, 565.10, P < 0.01). A trend of increasing detection rates with higher grade levels was observed (χtrend2=617.63, P < 0.01). Binary Logistic regression analysis indicated that students without boarding at school (OR=0.82, 95%CI=0.75-0.90), engaging in high-intensity physical activity for over 60 min per day ≥5 days per week (OR=0.90, 95%CI=0.82-0.98), and adequate sleep (OR=0.87, 95%CI=0.81-0.94) had lower risks of detecting spinal curvature abnormalities (P < 0.05).
The prevalence of spinal curvature abnormalities increases with grade level among primary and secondary school students in Guangxi. Regular moderate-to-vigorous physical activity demonstrates protective effects against spinal abnormalities.
