To explore the impact of social support on sleep quality among elderly people, and investigate the mediating role of anxiety symptoms between social support and sleep quality. The goal is to provide scientific evidence for improving sleep quality in this population.
Social Support scale, Generalized Anxiety Disorder 7-item (GAD-7), and Pittsburgh Sleep Quality Index (PSQI) were used to evaluate social support, anxiety symptoms and sleep quality of older adults. After excluding outliers and missing values, Pearson correlation analysis and multiple linear regression models were employed to examine the relationships among social support, anxiety symptoms, and sleep quality in older adults. The Bootstrap method was applied to test the mediating effect of anxiety symptoms.
A total of 1 194 participants were included, including 717 females (60.1%). Social support was negatively correlated with anxiety symptoms and sleep quality index (r= -0.180, P<0.001; r= -0.148, P<0.001), while anxiety symptoms were positively correlated with sleep quality index (r= 0.349, P<0.001). Mediation analysis revealed that anxiety partially mediated the relationship between social support and sleep quality, accounting for 37.5% of the total effect. Among men, anxiety symptoms accounted for 21.4% of the mediating effect, while among women, they accounted for 46.2%.
Better social support is associated with lower anxiety levels and improved sleep quality. Providing adequate social support for community-dwelling older adults is crucial for enhancing their sleep quality, physical health, and mental well-being.
