Objective: To describe the relationship between women's health and the timing, type, and duration of intimate partner violence (IPV) exposure.
Methods: A telephone interview was completed by 3429 women aged 18 to 64 randomly selected from a large health plan, to assess IPV exposure and heath status (response rate 56.4%). Questions from the Behavioral Risk Factor Surveillance System and the Women's Experience with Battering scale were used to construct IPV exposures: (1) recent (past 5 years) and remote (before past 5 years only) IPV exposure of any type (physical, sexual, or non-physical); (2) recent (past 5 years) IPV exposure to physical and/or sexual or non-physical only; and (3) IPV duration (0 to 2 years, 3 to 10 years, and >10 years). Health outcomes were measured using the Short Form-36 survey (SF-36), the Center for Epidemiologic Studies Depression scale, and the National Institute of Mental Health Presence of Symptoms survey.
Results: In adjusted models, compared to women with no IPV in their adult lifetime, more-pronounced adverse health effects were observed for women with recent (vs remote) IPV; for physical and/or sexual (vs non-physical) IPV; and for longer IPV exposure. Compared to women who never experienced IPV, women with any recent IPV (physical, sexual, or non-physical) had higher rates of severe (prevalence ratio [PR]=2.6; 95% confidence interval [CI]=1.9-3.6) and minor depressive symptoms (PR=2.3; 95% CI=1.9-2.8); higher number of physical symptoms (mean, 1.0; 95% CI=0.7-1.2); and lower SF-36 mental and social functioning scores (range, 4.3-5.5 points lower across subscales). Women with recent physical and/or sexual IPV were 2.8 times as likely to report fair/poor health, and had SF-36 scores that ranged from 5.3 to 7.8 points lower, increased risk of depressive symptoms (PR=2.6) and severe depressive symptoms (PR=4.0), and more than one additional symptom. Longer duration of IPV was associated with incrementally worse health.
Conclusions: Women's health was adversely affected by the proximity, type, and duration of IPV exposure.
