Associations of sleep quality, anxiety symptoms and social support with subjective well-being among Chinese perimenopausal women.

Background: Few studies have explored the internal pathway of the association between sleep quality and subjective well-being among perimenopausal women.

Methods: A survey was performed of 1063 perimenopausal women aged 40 to 60 years who participated in a regular health examination conducted at the First Hospital of Jilin University, China. Participants were asked to complete a study questionnaire. The Pittsburgh Sleep Quality Index, Zung Self-rating Anxiety Scale, Perceived Social Support Scale and Subjective Well-being Scale for Chinese Citizens were used to assess sleep quality, anxiety symptoms, social support and subjective well-being, respectively. The data were analyzed using t-tests, analysis of variance, Pearson correlation analysis, multiple linear regression analysis and the PROCESS macro.

Results: The mean total subjective well-being score was 90.14 ± 12.80. The correlation analyzes showed that sleep quality (r = -0.341, P < 0.001) and anxiety symptoms (r = -0.490, P < 0.001) were negatively correlated with subjective well-being. Social support was positively correlated with subjective well-being (r = 0.480, P < 0.001). The effect of sleep quality on subjective well-being was partially mediated by anxiety symptoms (Effect = -0.462, 95% CI = [-0.577, -0.363]). In addition, social support moderated the association between anxiety symptoms and subjective well-being (Index = -0.006, 95% CI = [-0.012, -0.001]).

Limitations: This was a cross-sectional study.

Conclusions: The effect of sleep quality on subjective well-being was partially mediated by anxiety symptoms, and social support moderated the association between anxiety symptoms and subjective well-being among perimenopausal women.
