摘要

This study aimed to assess how sleep quality affects mental health in adults.

The mean differences (MDs), along with 95% confidence intervals (CIs), were calculated from the retrieved data using a continuous model with random- or fixed-effects. Approximately 54 papers, comprising a total of 10,196 adults and conducted between 1998 and 2024, were included in this meta-analysis.

Improving sleep significantly reduced depression (MD, -2.92; 95% CI, -3.61 to -2.24, P-value< 0.001) and anxiety (MD, -1.14; 95% CI, -1.32 to -0.97, P-value< 0.001) compared to standard care among adults. However, no significant difference was observed in stress (MD, -1.03; 95% CI, -2.31 to 0.25, P-value= 0.11) between improving sleep and standard care among adults.

Analysis showed that improving overall sleep quality significantly reduced depression and anxiety, though no significant difference was observed in stress compared to standard care among adults. However, considering that the majority of studies had limited sample sizes, the results warrant careful interpretation.
