Domestic Violence as a Risk Factor for Attempted Suicide in Married Women.

High rates of suicide attempts and domestic violence (DV) in women of reproductive age group have been reported from South India, but the association between them was not studied. Hence, this study was undertaken to assess whether DV is a risk factor for attempted suicide in married women of reproductive age group. A hospital-based case-control study with 77 incident cases of attempted suicide in married women of the age group of 18 to 45 years and 153 controls belonging to the same age group, without history of suicide attempt, was undertaken over a period of 6 months. Univariate and multivariate analyses were done. The crude odds ratio (cOR) for DV was found to be 6.15 (95% confidence interval [95% CI] = [2.95, 12.82], p value = .0001). Other statistically significant risk factors included younger age group (below 30 years); gross family income > Rs. 5,000; higher occupational status of spouse; having poor social support; having a family history of psychiatric disorders, substance use disorders, and suicide/suicide attempt; higher impulsiveness scores; having higher scores of stressful life events over the past 12 months, and alcohol use disorder in husband. Islamic faith was found to be a significant protective factor. On logistic regression, DV was found to be an independent risk factor for attempted suicide in this study population (adjusted OR = 3.79, 95% CI = [1.35, 10.62], p value = .011). Age groups, stressful life events, impulsiveness, and alcohol use disorder in husband were the confounders adjusted for in logistic regression along with other significant risk and protective factors. Significant dose-response relationship was also observed between DV and attempted suicide. In accordance with the stress-diathesis model for suicidal behavior, DV is found to be a stressor which precipitates suicide attempt in those with diathesis like family history of psychiatric disorders. Clinical, research, and policy implications of the findings are discussed.
