Abstract:
Objective:To examine the association between moderate-to-vigorous physical activity (MVPA) and weight adjusted waist index (WWI) with psychological sub health in middle school students,so as to provide a basis for mental health intervention and promotion.
Methods:From September to November 2023, a stratified cluster random sampling method was used to survey 47 372 middle school students aged 12-17 in Jiangsu, Xinjiang, Guangdong, Jilin and Henan provinces from eastern, western, southern, northern and central of China. MVPA, WWI, and psychological subhealth were assessed, with WWI categorized into quartiles ( Q 1- Q 4). Data were analyzed using χ 2 test, Logistic regression analysis and Logistic regression analysis of generalized linear models.
Results:The overall prevalence of psychological sub health among middle school students was 21.0%, with higher rates in boys(21.4%) than girls(20.5%) ( χ 2=6.49, P <0.05). The detection rates of emotional problems, behavioral problems and social adaptation difficulties in middle school students were 27.8%, 26.9% and 17.5%, respectively. The combination of MVPA and WWI groups was used as independent variables, and the covariates were adjusted to perform Logistic regression analysis of generalized linear model;while the Q 1 group with MVPA>60 min/d was used as the reference group, the Q 4 group with MVPA<30 min/d had the highest risk of psychological sub health detection( OR =1.58, 95% CI =1.38-1.81),and the detection risks of psychological sub health among middle school students in Q 1- Q 3 groups were 1.34(1.17-1.53), 1.30(1.13-1.49) and 1.42(1.24- 1.62 )( P <0.01).
Conclusions:MVPA and WWI are significantly associated with psychological sub health in middle school students. Lower MVPA and higher WWI in middle school students correlate with increased sub health risks. Interventions should aim to enhance MVPA levels and reduce WWI to improve mental well being in middle school students.
