The impact of lifestyle sports on the sleep quality of depressed high school students in Jiangsu Province, China: based on cross-sectional study.

OBJECTIVE

Lifestyle sports refer to the stable forms and behavioral characteristics formed by individuals or groups of individuals who regularly and consciously participate in sports activities, which are divided into six dimensions: joviality type, challenge type, health type, beauty type, study type, and society type. High school students have a high prevalence of depression, and lifestyle sports are important factors affecting depression and depression-induced sleep quality problems. This paper intends to investigate the relationship between the six dimensions of lifestyle sports and the sleep quality of depressed high school students.

METHODS

In 129 high schools in 13 cities of Jiangsu Province, approximately 300 male and female students were selected for a questionnaire survey in each high school via the Lifestyle Sports Scale, the Self-rating Depression Scale (SDS), and the Pittsburgh Sleep Quality Index Scale (PSQI), and a stratified random sampling method was used. A total of 40,000 questionnaires were distributed, and 32,974 questionnaires were valid. The mediation model of depression between lifestyle sports and sleep quality was constructed via the Model4 model and other models in the SPSS macro program Process4.0. From the 32,974 valid questionnaires, 14,943 depressed high school students (SDS ≥ 53) were screened out, and structural equation modeling of the relationships between the six dimensions of lifestyle sports and the sleep quality of depressed high school students has been established via AMOS 28.0.

RESULTS

(1) Lifestyle sports significantly and positively predicted depression (P < 0.001), positively predicted sleep quality (P < 0.001), and depression significantly and positively predicted sleep quality (P < 0.001), and depression significantly mediated the relationship between high school students' lifestyle sports and sleep quality (β = 0.004, accounting for 29.91% of the total effect value). (2) The joviality type, challenge type, health type, beauty type, study type and society type of lifestyle sports significantly and positively predicted sleep quality in depressed high school students (P < 0.01), with the correlation coefficients between joviality type (β = 0.75, P < 0.01) and study type (β = 0.75, P < 0.01) of lifestyle sports and the sleep quality of depressed high school students being the largest.

CONCLUSION

Depression significantly mediated the relationship between lifestyle sports and sleep quality in high school students. All six dimensions of lifestyle sports are significantly positively correlated with sleep quality in depressed high school students, with the strongest correlations for the joviality type and study type.
