Abstract Background As global aging accelerates, depression among the elderly becomes more common. Research had revealed that patients with late-life depression (LLD) face a higher risk of suicide compared to their counterparts in other age groups, with the pathways to suicide being multifaceted. Thus, investigating the various factors linked to the elevated risk of suicide in patients with LLD is critical. Objective To investigate the factors associated with a high level of suicide risk among patients with LLD. Methods A total of 108 patients with LLD were recruited for this study. From October 2022 to November 2023, a cross-sectional study was conducted on patients with LLD from the Affiliated Brain Hospital of Guangzhou Medical University. Suicide risk was evaluated using the Chinese version of the Nurses’ Global Assessment of Suicide Risk Scale (NGASR). Potential influencing factors were included and analyzed through multivariate linear regression to identify the factors associated with a high level of suicide risk among patients with LLD. Results The mean NGASR score among patients with LLD was 7.30 ± 4.34 (range: 0 ~ 19). Multiple linear regression analyses revealed that depression-anxiety of the Brief Psychiatric Rating Scale (BPRS) (β = 0.31, 95% CI = 0.13, 0.45, p<0.001), activation of the BPRS (β=-0.29, 95% CI=-1.22, -0.35, p<0.001), normal cognitive function of the Mini-Mental State Examination (MMSE) (β = 0.21, 95% CI = 0.50, 3.48, p<0.05), involuntary admission (β = 0.20, 95% CI = 0.44, 3.43, p<0.05), and objective support of the Social Support Rating Scale (SSRS) (β = 0.21, 95% CI = 0.08, 0.66, p<0.05) were statistically associated with a high level of suicide risk in patients with LLD. Conclusion This study found that LLD patients with severe depression-anxiety, low activation, normal cognitive function, involuntary admission, and strong objective support exhibited a high level of suicide risk. These patients should receive intensified monitoring and comprehensive measures should be implemented to prevent the occurrence of suicidal behaviors during hospitalization.
