Depression, Anxiety, and Stress Mediate the Relationship Between Poor Sleep Quality and Suicidal Ideation Among Young Chinese Men

OBJECTIVE: Poor sleep quality exacerbates suicidal ideation. Depression, anxiety, and stress may play important roles in this relationship. However, the underlying mechanisms remain unknown. METHOD: A total of 2,598 young men were recruited for a cross-sectional study focusing on a range of sociodemographic factors, emotions, sleep quality, and suicidal ideation. Parallel, serial, and moderated mediation models were used to determine whether depression, anxiety, and stress mediated the relationship between poor sleep quality and suicidal ideation. RESULTS: = 0.173, 95% CI: 0.150, 0.197). Self-reported measures and the study's cross-sectional design preclude the causal inferences reported. CONCLUSIONS: The findings of this study prompt clinical and scientific researchers to consider the interplay among affective disorders when investigating etiological and psychological factors that may contribute to suicidal ideation.
