Objectives. We investigated history of abuse and other HIV-related risk factors in a community sample of 490 HIV-positive and HIV-negative African American, European American, and Latina women. Methods. Baseline interviews were analyzed, and logistic regressions were used to identify predictors of risk for positive HIV serostatus overall and by racial/ethnic group. Results. Race/ethnicity was not an independent predictor of HIV-related risk, and few racial/ethnic differences in risk factors for HIV were seen. Regardless of race/ethnicity, HIV-positive women had more sexual partners, more sexually transmitted diseases, and more severe histories of abuse than did HIV-negative women. Trauma history was a general risk factor for women, irrespective of race/ethnicity. Conclusions. Limited material resources, exposure to violence, and high-risk sexual behaviors were the best predictors of HIV risk.
America is facing a public health crisis. HIV infection and AIDS among women in the United States have increased dramatically over the last decade.1 Although only 1 in 4 women in the United States is African American or Latina, these women represent 77% of the AIDS cases.1 These national rates are replicated in Los Angeles, Calif, where the HIV and AIDS incidence rate among African American women (21 per 100 000) was 10 times higher than the rate among European American women (2 per 100 000) and 3 times higher than the rate among Latina women (7 per 100 000).2 Several factors account for disproportionate HIV morbidity, including racial/ethnic group affiliation, socioeconomic status, overall health, sexual risk taking, and higher rates of sexually transmitted diseases (STDs).35 Women who report early and chronic sexual abuse have a 7-fold increase in HIV-related risk behaviors and markers of risk compared with women with us abuse histories.611 Furthermore, 1 in 3 women report sexual abuse before age 18 years, and 4 million women become domestic violence victims annually.12 However, when income is controlled, race/ethnicity does not appear to be a specific risk factor for violence.1315 Therefore, additional research is needed to better understand how histories of sexual and physical trauma may contribute to greater risks for HIV and AIDS in women, particularly women of color.
The associations between child sexual abuse and HIV-related risks in adulthood have been well documented.10,11,16 Child sexual abuse involving penetration, especially intrafamilial abuse, has been associated with high-risk sexual and reproductive behaviors17 and higher rates of revictimization.18,19 The success of HIV prevention messages for women may depend in part on addressing early sexual abuse,11 but few programs address the effects of abuse on sexual risk taking. Thus, recidivism to risky behavioral practices postintervention may be an unintended consequence of the failure of prevention programs to include a full spectrum of skills that women need to cope with past experiences. Child sexual abuse also is associated with higher rates of rape in adulthood for European American, African American, and Latina women.18 Thus, women may experience more than 1 traumatic sexual event, which may further increase their risk-taking behaviors.19 Research has also documented the effects of domestic violence on HIV-related risks and general health.20,21 Women who are HIV positive or negative, especially women of color, who report relationship violence have more partners and a diminished ability to effectively negotiate sexual decisions.22,23 Other research noted that African American survivors of trauma who are HIV positive were more likely to meet criteria for AIDS than were women who are HIV positive without such a history.21 These initial findings suggest the need to further clarify the associations between violence and HIV risks for other racial/ethnic groups of women who are HIV positive and negative.
This study investigated 2 questions: (1) Does a history of sexual and physical trauma make a significant independent contribution to HIV-related risk in women, compared with demographic and other known behavioral and psychosocial risk factors for HIV? and (2) Are there racial/ethnic differences in the relative contribution sexual and physical trauma make to HIVrelated risks? It was expected that women who are HIV positive or negative would differ on child sexual abuse history and trauma and that this variable would be a significant independent predictor of risk for HIV serostatus independent of race/ethnicity and other risk factors. However, it was also expected that the relative contribution sexual and physical trauma made to HIV-related risk would differ in each racial/ethnic group, with African American women more adversely affected by trauma than the other women were.
The University of California Los AngelesDrew Women and Family Project was the first National Institute of Mental Healthfunded longitudinal HIV study that included a racially/ethnically diverse sample of women who were HIV positive or negative. This 5-year study, conducted from 1994 to 2000, examined HIV- and non-HIV-related life stresses, sexual functioning, coping mechanisms, and disease progression. In this paper, only baseline data on the African American, Latina, and European American women, the 3 racial/ethnic groups at greatest risk for HIV and AIDS,1,2 were used to test the hypotheses. A community sample of 490 women was recruited from HIV and other service agencies in Los Angeles County. Women who were HIV positive responded to flyers, radio and print advertisements, and personal contacts. In addition, a stratified random sample of women who were HIV negative matched on race/ethnicity, age, education, marital status, and geographic residence was recruited with random-digit dialing and 1990 US census track data. Eligible women were invited to participate in 4-hour face-to-face interviews conducted by trained, racially/ethnically and linguistically matched female interviewers. This procedure was used to reduce possible culturally mediated obstacles to effective communication. All participants were paid $50 per session (see Wyatt and Chin24 for a detailed description of the study).
Sample The sample was relatively young (mean age = 36.1 years), high school educated (mean = 12.1 years of education), poor (average per capita monthly income = $856.87), underemployed (77.7% unemployed or employed part-time), and unmarried or unattached (61.3% had no current partner). Approximately 3% (n = 13) were virgins, 49% (n = 223) reported having 5 or fewer lifetime sexual partners, 18% (n = 82) had 6 to 10 partners, 15% (n = 70) reported up to 30 partners, and 15% (n = 69) reported having more than 30 sexual partners. Slightly less than half of the sample reported never having had an STD (46.8%, n = 214), and 49.2% (n = 225) reported having had 1 or more STDs. A disproportionately large percentage of women reported having had traumatic experiences. With regard to traumatic experiences, 49% (n = 222) were sexually abused as children, 43% (n = 197) were abused as adults, and 51% (n = 232) had been in a physically abusive relationship.
Measures HIV serostatus was determined by enzyme-linked immunosorbent assay and confirmed by Western blot and coded as HIV negative (0) or HIV positive (1). Sexual history was assessed with the Revised Wyatt Sex History Questionnaire,25 a 478-item structured interview that includes open- and closed-ended items that assessed sexual decision making about consensual and nonconsensual experiences. Test-retest reliability on closed-ended items (r = 0.90) and interrater reliability on open-ended items were established on a weekly basis (r = 0.95).26 STD history was assessed with 2 questions that inquired about the number and types of STDs they ever had. Participants' responses to questions about 6 of the most common STDs (i.e., syphilis, gonorrhea, chlamydia, genital warts, genital herpes, pelvic inflammatory disease) were summed into a total STD score. Number of lifetime male sexual partners was totaled and categorized into 0 sexual partners, 1 to 5 partners, 6 to 10 partners, 11 to 30 partners, and 31 or more partners. History of child sexual abuse was assessed with a series of questions that asked about nonconsensual sexual experiences before age 18 with an adult and consensual sexual experiences with someone at least 5 years older. Nine questions assessed incidents of fondling, frottage, attempted or completed intercourse, oral sex, and type of penetration. Responses were coded as "yes" to any of the questions (1) or "no" to all questions (0). Type of child sexual abuse also was coded as none (0), and extrafamilial abuse (1), or intrafamilial abuse (2) depending on the relationship to the perpetrator. Adult sexual abuse was assessed by questions about rape or attempted rape before and since age 18. "Yes" responses to either question were coded as (1), and "no" responses were coded as (0). Relationship violence was assessed with 4 items from the Conflict Tactics Scale.27 Each respondent was asked whether in the last 6 months her partner threw, smashed, hit, or kicked something; slapped or physically attacked or hurt her; or threatened her with or used a knife or gun. If any of these behaviors occurred, respondents also were asked if the events occurred during pregnancy and summed into a total score. Finally, and to capture the full burden of traumatic experiences for each woman, a trauma index variable was calculated and included history of child sexual abuse, adult sexual abuse, and physical violence or conflict. Participants who did not have any of these experiences were coded as (0), those with at least 1 experience were coded as (1), and those with 2 or more experiences were coded as (2).
Data Analyses
Predictors were analyzed with best subset stepwise selection and included race/ethnicity, education, employment, per capita income, history of trauma, number of STDs, and number of sexual partners. Two dummy variables were created for race/ethnicity, contrasting each of the minority groups with European Americans. In addition, per capita income was standardized with a square root transformation, and number of sexual partners was standardized with log transformation. Finally, trauma history was recoded to reflect severity of traumatic experiences. Women with no trauma histories were coded (0), those with trauma scores of 1 to 3 were coded (1) (i.e., have less severe trauma history), and those with trauma scores of 4 or more were coded (2) (i.e., have more severe trauma history). F to enter was set = 1.0 and to remain = 1.1. Odds ratios (ORs) for each predictor variable were estimated from the logistic regression (Table 2
Group Differences in Background Characteristics Tests for group differences, by race/ethnicity and HIV serostatus, in demographic characteristics and other predictors are included in Table 1
In addition, among the women who were HIV negative, more African Americans were single or divorced (74%, n = 35) than were the Latina (48%, n = 25) and European American women (34%, n = 20) ( Consistent with expectations, race/ethnicity (F2,432 = 42.77, P < .001) and HIV-serostatus (F2,432 = 39.12, P < .001) differences in per capita income also were significant. European American women had significantly higher average monthly per capita incomes (mean = $1628) than did African American and Latina women (mean = $803 and $423, respectively), and African American women reported higher incomes than did Latina women (P = .007). Women who were HIV positive in all racial/ethnic groups reported significantly lower average per capita incomes than did their seronegative counterparts. However, the racial/ethnic difference was moderated by HIV serostatus (F2,432 = 8.69, P < .001). European American women who were HIV negative reported significantly higher average monthly per capita incomes (mean = $2215) than did all other groups. African American women who were HIV negative also reported significantly higher average monthly per capita incomes (mean = $1218) than did both groups of Latina women and than did African American women who were HIV positive but not significantly higher than did European American women who were HIV positive (mean = $1040). These results suggested that being HIVpositive was associated with significantly lower income for women of all racial/ethnic groups, but this effect was most pronounced among the African American women. Latina women were significantly poorer than the other groups, regardless of their HIV serostatus. Comparisons of unadjusted average monthly household incomes also were examined, and the results indicated that Latina women had significantly lower unadjusted monthly family incomes (mean = $1460) than did both European American and African American women (mean = $3602 and $1993, respectively). The income difference between the European American and African American women also was significant (F5,437 = 28.2, P < .001). Latina women earned lower incomes and had more dependents than did both of the other groups, and European American women earned higher incomes and had fewer dependents than did African American women.
Group Differences in STD History
Group Differences in Trauma
Predictors of HIV Seropositivity The model predicting HIV seropositivity with the entire sample indicated that women who had more sexual partners (OR = 1.471; 95% confidence interval [CI] = 1.179, 1.836), who were unemployed (OR = 0.349; 95% CI = 0.256, 0.475), who had more STDs (OR = 1.399; 95% CI = 1.089, 1.798), who had a more severe history of trauma (OR = 1.693; 95% CI = 1.163, 2.464), and who were less educated (OR = 0.903; 95% CI = 0.836, 0.976) were more likely to be HIV seropositive. This was a strong model, with percentage concordance = 82.0% and percentage discordance = 17.8%. It is particularly noteworthy that race/ethnicity was not an independent predictor of risk when other risk factors were considered. The models predicting HIV seropositivity in each of the racial/ethnic groups separately confirmed this general conclusion. The model predicting risk in the African American women indicated that only unemployment (OR = 0.193; 95% CI = 0.108, 0.344) and number of sexual partners (OR = 1.809; 95% CI = 1.228, 2.664) conferred the greatest risk for HIV in this group. For European American women, HIV seropositivity was predicted by unemployment (OR = 0.404; 95% CI = 0.252, 0.646), low education (OR = 0.769; 95% CI = 0.649, 0.911), and number of sexual partners (OR = 1.477; 95% CI = 1.073, 2.034). Finally, the model for Latina women indicated that HIV risk was predicted by number of STDs (OR = 6.240; 95% CI = 2.247, 17.330), unemployment (OR = 0.429; 95% CI = 0.222, 0.829), and number of sexual partners (OR = 1.777; 95% CI = 1.104, 2.859). Consistent with expectations, history of trauma was a risk factor overall for these women. However, no racial/ethnic differences were found in the relative contribution this factor made to HIV-related risk, and African American women evidenced no greater vulnerability to this risk factor. All of the models were strong, with percent concordance ranging from 79.0 to 83.0, with the highest rate in the model for European Americans and the lowest in the model for Latina women. Percent discordance ranged from 16.1 to 17.0.
This study examined whether a history of traumatic life experiences would be an independent predictor of HIV-related risk in a multiethnic sample of African American, Latina, and European American women who were HIV positive and HIV negative and whether there would be racial/ethnic differences in the relative contribution trauma made to risks for this disease. This diverse sample of women who were HIV positive or HIV negative was relatively young, poor, undereducated, underemployed, and not in stable relationships. The Latina women were younger, poorer, and less educated but more likely to be married or living with a partner than were the other women. Women were moderately sexually active and had moderate rates of STDs; Latina women reported fewer sexual partners, and fewer had histories of STDs. However, the regression model for Latina women suggested that their lower burden of risk factors did not alter the relative contributions these factors made to risk. The results also indicated that regardless of race/ethnicity, the women who were HIV positive reported having more sexual partners, more STDs, and more severe histories of abuse than did their counterparts who were HIV negative. African American women who were HIV positive were more likely to report histories of severe child sexual abuse, and this may have increased sexual risk-taking practices. Perhaps the most important finding of the study was that women's HIV risk was not a function of their race/ethnicity. Instead, the observed higher morbidity and mortality rates for HIV and AIDS in women of color were not specifically attributable to their race/ethnicity but rather were likely attributable mainly to differences in socioeconomic resources, exposure to violence, and exposure to risky sexual behaviors. Several implications can be derived from these findings. For example, most HIV prevention programs address only consensual sexual practices and fail to address the psychological consequences of early abuse on sexual decision making.28 Our findings suggested that sexual abuse, incidents of attempted and completed rape since age 18, and physical abuse in childhood and adulthood conferred additional risk for HIV infection. The use of a composite trauma index provided a clearer picture of the effect of cumulative exposure to interpersonal violence on HIV-related risks in these women. Although attention is currently being focused on HIV exposure prophylaxis when persons who are HIV positive suspect that they have been reexposed to HIV, less attention has been given to the possibility that women who are HIV infected also may be at risk for revictimization through coercion and rape. More research is needed on the causal direction of this relation. Perhaps the same factors that increase HIV risks for women also place them at risk for nonconsensual sex. It is also important to note that although more African American women were victims of violence, the relative significance of this risk factor was not moderated by race/ethnicity but was a general risk factor irrespective of race/ethnicity. This issue merits attention from health care providers and health researchers.2931 Coercive and abusive relationships limit a woman's ability to effectively negotiate safer sex and also may be indirectly associated with involvement with multiple partners or "survival sex" for financial stability. Greater economic dependence on partners can limit women's personal control over HIV risk practices.22,24 These findings also indicated that deprivation of socioeconomic resources, especially the psychological benefits of employment and education, may be more important than income and other factors in increasing risks for this disease.32 They are likely one of the major contributors to observed differences in HIV-related morbidity and mortality. However, within-group analyses can be useful in exploring possible group differences in the relative contributions different risks and protective factors make in conferring risk and protecting women from HIV and AIDS.
