BackgroundLiving alone has been suggested as a risk factor for suicide. However, the effect on suicide risk of living together with spouse, child(ren) and parent(s) is unclear. This study aims to examine the association between living arrangements with spouse, child(ren), and parent(s) and suicide in a Japanese men and women.MethodsAltogether 104, 528 participants aged 40-69Â years, who completed baseline questionnaire (1990-1994), were followed for death through December 2005. We used Cox proportional hazards regression model to estimate the hazard ratio (HR) and 95% confidence intervals (95% CI) for suicide according to living arrangements.ResultsDuring an average 13.2-year follow up, 406 suicidal deaths were recorded. Men living without a spouse and women living with a parent(s) only were at increased risk of suicide than those living with a spouse only. The multivariate HR (95% CI) in men were as follows: “living with a parent(s) only”, 1.86 (1.03-3.36); “living with a child(ren) only”, 2.20 (1.32-3.66); “living with a parent(s) and child(ren)”, 1.95 (1.02-3.72); and “living alone”, 1.80 (0.99-3.25); and in women was as follow “living with a parent(s) only”, 3.80 (1.90-7.61). Suicide risk was significantly decreased among women living with a spouse and child(ren) as compared with women living with a spouse only (HR 0.58, 95%CI 0.34 to 0.98).ConclusionsMen living without a spouse and women living with a parent(s) only were at increased risk of suicide. Women living together with a spouse and child(ren) were at decreased risk of suicide.
