The independent and combined effects of physical and sexual abuse on health. Results Of a national survey

Background: Although physical and sexual abuse have been linked to health risk behaviors as well as mental health problems, it is unclear whether those young women who have experienced both physical and sexual abuse are at greatest risk. To examine the independent associations between physical, sexual, and/or both types of abuse and health status, mental health, and health risk behaviors among a national school-aged sample of girls. We hypothesized that the magnitude of risk would be highest for those reporting both types of abuse compared to those reporting neither or one type of abuse. Methods: In 1997, 3,015 girls in grades 5 through 12 participated in the Commonwealth Fund Adolescent Health Survey and responded to both questions inquiring about physical and sexual abuse. This sample was derives from a nationally representative cross-section of 265 public, private, and parochial schools with an oversampling of 32 urban schools to obtain ethnic diversity. Data were analyzed using chi-square and binary or multinomial logistic regression stratified by type of abuse (none, physical abuse, sexual abuse, or both). Results: About 8% (n = 246) of girls reported a past history of only physical abuse, 5% (n = 140) reported only sexual abuse, and 5% (n = 160) reported experiencing both physical and sexual abuse. Logistic regression controlling for demographic characteristics (grade level, ethnicity, family structure, and socioeconomic status) found those who reported both types of abuse as compared to those who did not report any abuse were significantly more likely to experience moderate-to-severe depressive symptoms (OR = 5.1), moderate to high life stress (OR = 3.3), history of bingeing and purging behavior (OR = 4.4), regular smoking (OR = 5.9) regular drinking (3.8), illicit drug use in the past 30 days (RR = 3.5) and fair to poor health status (OR = 1.9). In contrast, lowered adjusted odds ratios (1.8-2. 5) were seen for those reporting one type of abuse as compared to no abuse across most health outcomes.Conclusions: Those experiencing any type of abuse are at risk; however, those adolescent females who report both physical and sexual victimization are at much greater risk.
