Intimate partner violence against women with disability and associated mental health concerns: a cross-sectional survey in Mumbai, India

OBJECTIVES: The risk of intimate partner violence (IPV) against women with disability is believed to be high. We aimed to compare the prevalence of past-year IPV against women with and without functional difficulties in urban informal settlements, to review its social determinants and to explore its association with mental health. DESIGN: Cross-sectional survey. SETTING: Fifty clusters within four informal settlements. PARTICIPANTS: 5122 women aged 18–49 years. PRIMARY AND SECONDARY OUTCOME MEASURES: We used the Washington Group Short Set of Questions to assess functional difficulties. IPV in the past year was described by binary composites of questions about physical, sexual and emotional violence. We screened for symptoms of depression using the Patient Health Questionnaire-9 and of anxiety using the Generalised Anxiety Disorder-7. Multivariable logistic regression models examined associations between functional difficulties, IPV and mental health. RESULTS: 10% of participants who screened positive for functional disability had greater odds of experiencing physical or sexual IPV (adjusted OR (AOR) 1.68, 95% CI 1.23 to 2.29) and emotional IPV (1.52, 95% CI 1.16 to 2.00) than women who screened negative. Women who screened positive for functional disability had greater odds than women who screened negative of symptoms suggesting moderate or severe anxiety (AOR 2.50, 95% CI 1.78 to 3.49), depression (2.91, 95% CI 2.13 to 3.99) and suicidal thinking (AOR 1.94, 95% CI 1.50 to 2.50). CONCLUSIONS: The burden of IPV fell disproportionately on women with functional difficulties, who were also more likely to screen positive for common mental disorder. Public health initiatives need to respond at local and national levels to address the overlapping and mutually reinforcing determinants of violence, while existing policy needs to be better utilised to ensure protection for the most vulnerable.
