Intimate partner violence perpetration, standard and gendered STI/HIV risk behaviour, and STI/HIV diagnosis among a clinic-based sample of men.

BACKGROUND: The estimated one in three women worldwide victimized by intimate partner violence (IPV) consistently demonstrate elevated STI/HIV prevalence, with their abusive male partners' risky sexual behaviours and subsequent infection increasingly implicated. To date, little empirical data exist to characterise the nature of men's sexual risk as it relates to both their violence perpetration, and STI/HIV infection.
METHODS: Data from a cross-sectional survey of men ages 18-35 recruited from three community-based health clinics in an urban metropolitan area of the northeastern US (n = 1585) were analysed to estimate the prevalence of IPV perpetration and associations of such violent behaviour with both standard (eg, anal sex, injection drug use) and gendered (eg, coercive condom practices, sexual infidelity, transactional sex with a female partner) forms of sexual-risk behaviour, and self-reported STI/HIV diagnosis.
RESULTS: Approximately one-third of participants (32.7%) reported perpetrating physical or sexual violence against a female intimate partner in their lifetime; one in eight (12.4%) participants self-reported a history of STI/HIV diagnosis. Men's IPV perpetration was associated with both standard and gendered STI/HIV risk behaviours, and to STI/HIV diagnosis (OR 4.85, 95% CI 3.54 to 6.66). The association of men's IPV perpetration with STI/HIV diagnosis was partially attenuated (adjusted odds ratio (AOR) 2.55, 95% CI 1.77 to 3.67) in the multivariate model, and a subset of gendered sexual-risk behaviours were found to be independently associated with STI/HIV diagnosis-for example, coercive condom practices (AOR 1.67, 95% CI 1.04 to 2.69), sexual infidelity (AOR 2.46, 95% CI 1.65 to 3.68), and transactional sex with a female partner (AOR 2.03, 95% CI 1.36 to 3.04).
CONCLUSIONS: Men's perpetration of physical and sexual violence against intimate partners is common among this population. Abusive men are at increased risk for STI/HIV, with gendered forms of sexual-risk behaviour partially responsible for this association. Thus, such men likely pose an elevated infection risk to their female partners. Findings indicate the need for interwoven sexual health promotion and violence prevention efforts targeted to men; critical to such efforts may be reduction in gendered sexual-risk behaviours and modification of norms of masculinity that likely promote both sexual risk and violence.

STI/HIV is rapidly spreading among young urban men and women in the USA, with an estimated half of all new infections occurring among those ages 15–24 years.1 Evidence from the USA and elsewhere illustrates women’s elevated STI/HIV risk based on their intimate partner victimisation (IPV),2 3 4 5 6 with abusive male partners’ sexual-risk behaviour7 8 9 10 11 12 13 14 15 16 17 and subsequent STI/HIV infection8 9 15 17 increasingly considered responsible for this association.

As IPV cannot cause STI/HIV in the absence of pathogen exposure, the body of research devoted to understanding elevated STI/HIV among male IPV perpetrators has largely focused on articulating patterns of STI/HIV risk behaviour among this population. Standard STI/HIV risk behaviours, that is, those commonly assessed within surveillance efforts18 19 and recommended for behavioural interventions,20 21 22 (eg, multiple sex partnering, inconsistent condom use, injection drug use and anal sex) are consistently found to be more prevalent among IPV perpetrators.10 11 12 13 14 15 16 17 These data suggest that male perpetrators of violence are more likely to contract and transmit STI/HIV infection based on such behaviour.

A growing body of research suggests that men’s abuse of female partners reflects gender-based power imbalances which may extend to gendered forms of sexual-risk behaviour.10 23 While the standardly assessed STI/HIV risk behaviours described above may reflect gender-based power imbalances, recent attention to the gendered nature of STI/HIV risk24 25 26 has prompted increased recognition of sexual-risk behaviours that are explicitly rooted in gender-based power imbalances and, importantly, may also represent additional dimensions of infection risk. For example, coercive sexual negotiation (eg, women’s limited ability to refuse sex or insist on condom use in the face of violence) is common in the context of abuse;14 27 28 29 30 consequent unwanted and unprotected sex may prompt physical trauma (ie, tearing or lacerations).26 31 Thus, coercive sexual negotiation may heighten the risk for sexual transmission from an infected partner. IPV perpetrators are also more likely to engage in transactional sex (ie, engaging in sex with women in prostitution7 10 16) as well as other materially or financially motivated sexual encounters;7 such behaviour is considered to both manifest gendered power and control7 and, importantly, represent higher-risk sexual contact with respect to STI/HIV.32 33 34 Extramarital partnering and other forms of sexual infidelity (ie, concurrent undisclosed sexual partnerships) similarly pose both additional STI/HIV risk35 and relate to men’s IPV perpetration.8 9 Such infidelity likewise appears rooted in gender-based power imbalances and culturally sanctioned norms of masculinity.36 37 Taken together, these data illustrate that, in addition to standard STI/HIV risk behaviours found to be more prevalent among abusive men, gendered sexual-risk behaviours (ie, related to men’s entitlement to sexual power, control and access) may represent additional and distinct infection risk and, perhaps, partially explain their increased likelihood of STI/HIV acquisition and subsequent transmission.

However, previous studies have not simultaneously considered standard and gendered STI/HIV risk behaviours. Such designs are necessary for determination of which forms of risk are most relevant in explaining the elevated prevalence of STI/HIV among abusive men and, by extension, mechanisms by which abusive men may be most likely to become infected (ie, whether IPV perpetration may be a marker for abusive men’s greater likelihood to engage in standard forms of STI/HIV risk behaviour, and/or whether abuse may reflect greater engagement in gendered, and qualitatively different, forms of sexual risk which in turn may pose risk for STI/HIV acquisition and transmission).

The current study is designed to estimate associations of (1) IPV perpetration with both standard (eg, injection drug use, anal sex, multiple partnering) and gendered (eg, coercive condom negotiation practices, sexual infidelity, sex purchasing) forms of STI/HIV risk behaviour, (2) IPV perpetration and both standard and gendered STI/HIV risk behaviours with STI/HIV diagnosis and (3) IPV perpetration with STI/HIV diagnosis while controlling for standard and gendered STI/HIV risk behaviours among a clinic-based sample of young urban men.

Methods

Design and setting

The current study utilises data collected between January 2005 and December 2006 via a cross-sectional survey conducted in collaboration with three urban community health centers (CHC). At each CHC, all English-, Spanish- or Portuguese-speaking men presenting to the main reception desk were screened for eligibility (ages 18–35 years) by trained research staff fluent in these languages. As this investigation was originally designed to evaluate risk and protective factors for IPV perpetration, the age range 18–35 years was selected to maximise statistical power, as this age group is considered at greatest risk for such perpetration.38 Those meeting eligibility criteria and expressing interest in the study were escorted to a private area of the CHC where verbal consent was obtained to preserve participant anonymity. Following informed consent procedures, participants completed a survey using Audio Computer-Assisted Survey Instrument (ACASI), a computer-based survey tool in which participants self-administer the survey while questions and answer choices are read aloud to them over headphones to reduce potential literacy barriers. ACASI has been demonstrated effective in increasing reporting of sensitive behaviours39 and has been recommended specifically for research concerning violence perpetration.40 Following completion of the 30 min survey, participants received a $20 prepaid debit card and a list of local community resources for violence prevention, health promotion and mental health services. All study materials were available in English, Spanish and Portuguese. Of the 3430 men approached for the study, 2229 agreed to participate (65%). Given the need to obtain verbal consent prior to data collection, no data were obtained on non-participants. The primary reason for non-participation was lack of time. Of the 2229 participants, a small number were considered non-responsive based on extensive missing data (n = 75); of the remaining 2154 participants, 1711 men (79%) indicated ever having had sexual intercourse; 1585 (93%) provided complete data concerning the predictor and outcome variables; present analyses are limited to these 1585 participants. The youngest participants (men aged 18–21 years) were slightly more likely to fail to provide adequate data for analyses; no other evidence of bias was detected.

Measures

All measures were self-reported. Lifetime history of IPV perpetration against female partners was assessed via 14 items modified from the Conflict Tactics Scale 2 (CTS-2)41 and the Sexual Experiences Survey (SES).42 Six items assessed history of physical violence perpetration, and eight items assessed history of sexual violence perpetration against a female intimate partner (ie, a current or former dating or marital partner). Based on these assessments, a single dichotomous variable was created to reflect lifetime history of IPV perpetration such that report of any physical (eg, pushed, punched or shoved) or sexual (eg, insisted on sexual activity, used force for sexual activity) violence against an intimate partner indicated a lifetime history of IPV with those reporting no to all items serving as the referent group. Lifetime history of STI/HIV diagnosis was assessed via the single item, “Have you ever been told by a medical professional that you have a sexually transmitted disease (Chlamydia, herpes, gonorrhea, HIV, genital warts)?” Single items were also used to assess covariates of interest, specifically demographics (age, race/ethnicity and education level), standard STI/HIV risk factors (lifetime history of injection drug use, lifetime history of anal sex and past-year history of multiple sexual partners), and gendered STI/HIV risk factors specific to sexual encounters with female partners, specifically lifetime history of transactional sex, that is, “Have you ever traded drugs, money or a place to stay in exchange for sex from a girl or woman?,” lifetime history of anger in response to condom request, that is, “Have you ever gotten mad at a girl/woman for asking to use a condom when you have sex?,” lifetime history of coerced condom non-use, that is, “Have you ever made a girl/woman have sex without a condom even though she wanted to use one?,” lifetime history of sexual infidelity which serves as a proxy for concurrent sexual partnerships, that is, “Have you ever had sex with some other girl/woman when you were supposed to only be having sex with one girlfriend or wife of yours?”

Analysis

Prevalence estimates were calculated for lifetime IPV perpetration for the total sample and by demographic factors; differences in IPV perpetration based on these factors were assessed via χ2 analyses; significance for all analyses was set at p<0.05. Prevalence estimates for standard and gendered STI/HIV risk behaviours were calculated for the sample and based on male IPV perpetration. Logistic regression models were constructed to estimate odds ratios for each risk behaviour based on IPV perpetration, adjusted for all potential demographic confounders (ie, age, education and relationship status) and location of recruitment.

A final series of analyses considered the standard and gendered STI/HIV risk behaviours as exposures in order to determine their associations with STI/HIV diagnosis. Prevalence estimates of lifetime STI/HIV diagnosis were calculated for the total sample and by IPV perpetration and standard and gendered STI/HIV risk behaviours. Logistic regression models were constructed to estimate crude odds ratios (ORs) and 95% CIs of lifetime STI/HIV diagnosis based on the main exposure (IPV perpetration) and both standard and gendered STI/HIV risk factors. Finally, in order to evaluate the which standard and gendered STI/HIV risk behaviours may be responsible for associations of IPV perpetration with STI/HIV diagnosis, a multivariate model was constructed to consider all exposures, that is, IPV perpetration, and standard and gendered STI/HIV behaviours. The multivariate model was adjusted for all potential demographic confounders (ie, age, education and relationship status) and location of recruitment. The Harvard School of Public Health Human Subjects Committee approved all study procedures.

Results

Intimate partner violence perpetration

Approximately one in three (32.7%) participants reported a lifetime history of physical or sexual violence perpetration against a female partner (table 1). The prevalence of IPV perpetration varied across age groups, with men aged 22–25 years most likely to perpetrate (38.2%; p = 0.001).

IPV perpetration also varied across racial/ethic groupings, with non-Hispanic Black men reporting the highest levels of perpetration (35.9%), followed by non-Hispanic White men (33.3%; p = 0.032). No differences were detected based on education.

Intimate partner violence perpetration and standard and gendered STI/HIV Risk Behaviour

Both standard and gendered STI/HIV risk factors were more prevalent among IPV perpetrators as compared with their non-abusive counterparts (table 2). The most commonly reported standard STI/HIV risk behaviour was anal sex (45.6%), with IPV perpetrators over twice as likely to engage in such behaviour (58.8% vs 39.2%; adjusted odds ratio (AOR) 2.12, 95% CI 1.70 to 2.64). The most prevalent gendered STI/HIV risk behaviour was sexual infidelity, that is, cheating on a main partner (48.1%); IPV perpetrators demonstrated over three times the odds of engaging in such behaviour (AOR 3.91, 95% CI 3.10 to 4.91). Coercive condom practices in the forms of condom refusal and anger in response to condom request were common, and were more prevalent among IPV perpetrators relative to non-abusers (30.8% vs 10.4%; AOR 3.71, 95% CI 2.82 to 4.88; 22.5% vs 5.6%, AOR 4.88, 95% CI 3.47 to 6.85, respectively).

STI/HIV diagnosis

STI/HIV diagnosis across the lifetime was reported by 12.4% of men (table 3). IPV perpetration was bivariately associated with lifetime STI/HIV diagnosis, with approximately one-quarter of abusive men (24.9%) experiencing STI/HIV as compared with only 6.4% of non-abusive men. IPV perpetration as well as all forms of standard and gendered STI/HIV risk behaviour were associated with STI/HIV diagnosis in bivariate analyses. While partially attenuated, the association of IPV with STI/HIV diagnosis persisted in the multivariate model (AOR 2.55, 95% CI 1.77 to 3.67). Additional factors significantly associated with lifetime STI/HIV diagnosis in the multivariate model were gendered STI/HIV risk behaviours only, specifically having been sexually unfaithful (AOR 2.46, 95% CI 1.65 to 3.68), anger in response to condom request (AOR 1.67, 95% CI 1.04 to 2.69) and transactional sex (AOR 2.03, 95% CI 1.36 to 3.04).

Discussion

Findings indicate that, relative to their non-abusive counterparts, men who perpetrate violence against female partners engage in higher levels of both standard and gendered STI/HIV risk behaviour, and demonstrate an elevated prevalence of STI/HIV. Moreover, it appears that the elevated STI/HIV prevalence observed among abusive men may be better explained by gendered forms of STI/HIV risk behaviour (eg, sexual infidelity, coercive condom practices and involvement in transactional sex with a female partner) than standardly assessed risk behaviours. Given that almost one-third of participants reported perpetrating physical or sexual violence against a female partner, identified associations of IPV perpetration with gendered forms of STI/HIV risk and subsequent STI/HIV acquisition strongly indicate that men who perpetrate partner violence should be prioritised for intervention efforts as they likely, in addition to causing a broad range of physical and psychological injuries, pose heightened STI/HIV risk to their female partners.

Our findings of elevated sexual risk and STI/HIV diagnosis among male perpetrators of violence are consistent with prior research.8 9 10 14 15 16 43 Advancing this body of knowledge, current evidence indicates that the association of men’s IPV perpetration with their STI/HIV may be better explained by gendered than standard STI/HIV risk sources. While both standard (ie, anal sex, injection drug use) and gendered STI/HIV risk behaviours (ie, transactional sex, coercive condom practices, sexual infidelity) were found associated with both IPV perpetration and STI/HIV diagnosis, only gendered forms of sexual risk were independently associated with STI/HIV in the final multivariate model. Current findings advance our understanding of potential mechanisms underpinning findings of elevated STI/HIV among abusive men and suggest that the gendered, and potentially qualitatively riskier, sexual-risk behaviours more common among abusive men may contribute to their elevated STI/HIV infection.

Surprisingly, IPV perpetration remained significantly associated with STI/HIV diagnosis in the multivariate model adjusted for both standard and gendered risk behaviours. Its persistence suggests that, while IPV perpetration in itself cannot cause STI/HIV, men’s abusive behaviour constitutes a marker for risky sexual practices above and beyond those currently captured (eg, forced unprotected sex) and, notably, beyond those traditionally assessed in STI/HIV prevention efforts (eg, injection drug use, multiple partnering). The demonstrated inability of standardly assessed STI/HIV risk behaviours to explain abusive men’s elevated STI/HIV infection suggests that modification of these behaviours via traditional prevention strategies may be insufficient to reduce STI/HIV among IPV perpetrators and their female partners.

This finding also indicates that the range of STI/HIV risk behaviour assessed within the current study, while more detailed than standard surveillance methods,18 19 44 was still inadequate in scope and/or precision; factors not fully captured warrant further consideration, including coital frequency, context and nature of men’s anal sex (eg, receptive or insertive), and forced and unprotected sex in the contexts of both substance use45 and casual concurrent partnerships.14 Although female-to-male STI/HIV transmission is relatively inefficient biologically,46 and recent evidence indicates that abusive men are more likely than their non-abusive counterparts to acquire HIV outside the marital relationship,17 men may have acquired STI/HIV from their female partners, particularly if such women have been infected in a prior abusive relationship. Thus, consideration of female partner STI/HIV status will improve the clarity of future investigations. As IPV perpetration cannot directly cause STI/HIV, more comprehensive assessment of gendered sexual-risk behaviours should be a priority of future research. If gendered sexual risk does, indeed, account for much of the association of IPV with STI, inclusion of such improved assessment in models predicting STI/HIV will result in greater attenuation of the association of IPV with STI/HIV. In other words, if IPV is a marker for other gendered sexual-risk behaviours, the more comprehensive assessment of such behaviours will attenuate the role of IPV to a greater extent in predicting STI/HIV. Additional prospective investigation using couples as the unit of analysis is recommended to clarify the mechanisms and temporal sequencing of IPV perpetration, sexual risk and STI acquisition.

As has been posited in other contexts facing similar patterns of elevated STI/HIV risk among abusive men,10 17 24 men’s violence perpetration against female partners and gendered sexual risk may stem from a common source. Qualitative and quantitative evidence indicates that men’s endorsement of masculinity norms which support men’s entitlement to sexual control of women and adversarial sexual beliefs relate to both IPV perpetration23 47 48 and sexual-risk behaviour.7 23 45 48 Such individual and socially reinforced norms may explain the observed clustering of STI/HIV risk and diagnosis with IPV perpetration,10 24 and, as such, serve as a basis for further research and programmatic efforts to address these inter-related threats.

The current findings should be considered in light of several limitations in addition to those previously mentioned. Cross-sectional analysis precludes conclusions regarding temporality; prospective work is needed to determine the relative sequencing and impact of these STI/HIV risk behaviours and IPV on men’s STI/HIV acquisition and subsequent transmission. Several sampling issues should be considered, including the 65% response rate and the inability to study potential biases among non-respondents due to ethical considerations. Additionally, the prevalence of sexual intercourse was lower than anticipated for this adult sample and may reflect under-reporting possibly based on confusion regarding the terminology “sexual intercourse,” as no definition was provided. While the sample was limited to those men reporting sexual activity, STI/HIV can also be transmitted without penetrative sex. Younger men were slightly more likely to fail to provide complete data on the exposures and outcomes of interest. While these factors limit the generalizability of findings, the nature and direction of any potential bias introduced remain unclear. All data are self-reported, rendering them subject to potential inaccuracies attributable to social desirability, recall bias, intentional distortions or non-candid responses.49 Use of ACASI likely minimised these threats, given the demonstrated ability of ACASI to enhance the quality of assessment of sensitive behaviours.39 Reliance on self-reported STI/HIV diagnosis likely underestimates the number of individuals infected.50 Future studies including biological assessment of STI/HIV as well as more comprehensive and specific sexual-risk assessments (eg, condom non-use in the context of multiple partnering, coital frequency, forced unprotected sex) may clarify the current findings. Given the use of a single urban metropolitan area, with high representation from young men of colour, findings may not generalise to broader populations of men. However, the current sample may be considered particularly informative, as it reflects individuals receiving care within community-based health centres, suggesting that such men may be readily accessed for intervention in this medical setting. Moreover, the elevated STI/HIV risk demonstrated among this population1 44 51 52 53 highlights the relevance of the current sample for programmatic implications.

The current findings indicate a high level of IPV perpetration among young, urban, adult men attending community health centres, with approximately one in three men reporting perpetration of physical or sexual violence against an intimate partner. These abusive men’s increased risk of STI/HIV diagnosis appears to be better explained by their involvement in gendered forms of STI/HIV risk behaviour as compared with those more standardly assessed. These data bolster calls to integrate men’s violence perpetration prevention within STI/HIV prevention efforts,24 and indicate that such efforts should specifically target gendered STI/HIV risk behaviours. Integrated efforts should include a focus on modifying masculinity norms that support men’s entitlement to sexual control of and access to women, given evidence that such attitudes appear to underpin both IPV perpetration23 47 48 and sexual-risk behaviour.7 23 45 48 Recent evidence of intervention efficacy in reducing men’s IPV perpetration, sexual-risk behaviour and STI in the South African context54 suggest the utility of integrated efforts; current findings indicate the need to evaluate this prevention approach in the US to stem the increasingly interwoven epidemics of men’s IPV perpetration and STI/HIV.

Approximately one in three young adult urban men reported a lifetime history of physical or sexual violence perpetration against a female intimate partner.

Men’s abuse of their female partners was associated with elevated sexual risk as well as STI/HIV diagnosis.
