Abstract:
Objective:To analyze the association of sleep duration and emotional state with life satisfaction among upper grade primary school students in the context of the "Double Reduction" policy, so as to provide empirical evidence for improving children s sleep health and life satisfaction.
Methods:From May to June 2022, a stratified random cluster sampling method was employed to recruit 3 901 primary school students in grades 4 to 6 from Bobai County, Yulin City, Guangxi, for a questionnaire survey. The questionnaire covered demographic information, sleep duration, emotion, parental homework checking frequency, after-school tutoring satisfaction and Multidimensional Students Life Satisfaction Scale. Multivariate linear hierarchical regression and the PROCESS macro were adopted for statistical analysis.
Results:The score of students life satisfaction was 201.00 (184.00, 217.00). A total of 59.8% of the students slept for 9-10 hours, and 93.5% reported stable emotional state. Multivariate hierarchical linear regression analysis showed that, after controlling for variables such as gender, grade and annual family income, after-school tutoring satisfaction ( B =9.80), sleep duration ( B =3.26), frequency of parental homework checking ( B =4.06), annual family income ( B =1.99), and emotion ( B =9.35) were all positively associated with students life satisfaction (all P <0.05). Emotion played a partial mediating role between sleep duration and life satisfaction, with the mediating effect accounting for 25.8% (indirect effect=1.70, 95% CI =1.29-2.14). Gender-stratified analysis indicated that the mediating effect of emotional state between sleep duration and life satisfaction was statistically significant in both boys (indirect effect=1.40, 95% CI =0.91-1.95) and girls (indirect effect=2.08, 95% CI =1.44- 2.88 ). The proportion of mediating effect was slightly higher in girls (28.3%) than in boys (23.5%).
Conclusions:Emotion partially mediates the relationship between sleep duration and life satisfaction among upper-grade primary school students, and gender differences exist in the mediating mechanism. Collaborative interventions targeting sleep and emotional well-being should be promoted, and the "family-school-community" cooperative education system needs to be strengthened.
