Outline
To explore factors influencing suicidal behavior in patients with severe mental disorders.
Using cohort data from a western region of China (2006-2018), 332 298 patients were included. A multilevel logistic regression model was used to analyze factors associated with suicidal behavior (suicide death and suicide attempts).
Among 332 298 individuals, 3 358 experienced the outcome event, with an incidence of 1.01%. Multilevel logistic regression showed that female sex (OR=1.142, 95%CI: 1.058-1.234), other ethnicities (OR=1.609, 95%CI: 1.220-2.122), and non married status (OR=1.169, 95%CI: 1.064-1.285) were associated with higher risk, while age ≥46 years (46-60: OR=0.754, 95%CI: 0.669-0.849; 61-90: OR=0.708, 95%CI: 0.615-0.814) was associated with lower risk. When analyzing suicide attempts and suicide death separately, gender, ethnicity, and marital status were associated only with suicide attempt, whereas urban/rural residence and family history were associated only with suicide death. Follow-up time showed opposite effects on the two outcomes.
Prevention efforts should target high-risk populations, including those with risk assessment levels 3-5, other ethnicities, adverse drug reactions, ongoing pharmacotherapy, and higher education levels. Maintaining follow-up and establishing an integrated prevention network combining clinical and social factors is essential.
