Correlates of impulsivity among female sex workers in Mexico. Health Care Women Int 2023; 44:1119-1135. [PMID: 34427544 PMCID: PMC8866522 DOI: 10.1080/07399332.2021.1958816] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Accepted: 07/18/2021] [Indexed: 10/20/2022]
Abstract
Impulsivity is a trait characteristic that is associated with sexual risk behavior. We examined correlates of impulsivity among 602 female sex workers (FSWs) enrolled in a sexual risk reduction intervention in Mexico (2016-2020). Impulsivity was positively associated with condomless sex with clients. Higher levels of impulsivity were associated with greater use of alcohol and heavy drugs, use of illicit drugs with clients, sexual/physical abuse history, and clinical depression. Global public health policy that supports free substance abuse treatment in combination with psychotherapeutic treatments (e.g. regulation management skills) and behavioral-focused therapy may help to reduce HIV/STI incidence in this vulnerable population.

A comparison of the effectiveness of respondent-driven and venue-based sampling for identifying undiagnosed HIV infection among cisgender men who have sex with men and transgender women in Tijuana, Mexico. J Int AIDS Soc 2021; 24:e25688. [PMID: 33759361 PMCID: PMC7987819 DOI: 10.1002/jia2.25688] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Revised: 01/21/2021] [Accepted: 02/17/2021] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Efforts to increase HIV testing, diagnosis and care are critical to curbing HIV epidemics among cisgender men who have sex with men (MSM) and transgender women (TW) in low- and middle-income countries (LMIC). We compared the effectiveness of respondent-driven sampling (RDS) and venue-based sampling (VBS) for identifying previously undiagnosed HIV infection among MSM and TW in Tijuana, Mexico. METHODS Between March 2015 and December 2018, we conducted RDS within the social networks of MSM and TW and VBS at venues frequented by MSM and TW to socialize and meet sexual partners. Those reached by RDS/VBS who reported at least 18 years of age, anal sex with MSM or TW, and no previous HIV diagnosis were eligible for HIV testing. RESULTS Of those screened following recruitment via RDS (N = 1232; 98.6% MSM; 1.3% TW), 60.8% (749/1232) were eligible for HIV testing and 97.5% (730/749) were tested for HIV infection, which led to the identification of 36 newly diagnosed HIV infections (4.9%). Of those screened following recruitment via VBS (N = 2560; 95.2% MSM; 4.6% TW), 56.5% (1446/2560) were eligible for HIV testing and 92.8% (1342/1446) were tested for HIV infection, which led to the identification of 82 newly diagnosed HIV infections (6.1%). The proportion of new HIV diagnoses did not differ by recruitment method (ratio = 0.81, 95% confidence interval: 0.55 to 1.18). Compared to those recruited via RDS, those tested following recruitment via VBS were younger, more likely to identify as gay, and more likely to identify as TW. Compared to those recruited via VBS, those newly diagnosed with HIV infection following recruitment via RDS reported higher levels of internalized stigma and were more likely to report injection drug use and a history of deportation from the United States. CONCLUSIONS Despite RDS and VBS being equally effective for identifying undiagnosed HIV infection, each recruitment method reached different subgroups of MSM and TW in Tijuana. Our findings suggest that there may be benefits to using both RDS and VBS to increase the identification of previously undiagnosed HIV infection and ultimately support HIV care engagement among MSM and TW in Mexico and other similar LMIC.

Recent HIV Infection among men who have sex with men and transgender women in Tijuana. Rev Saude Publica 2020; 54:82. [PMID: 32876301 PMCID: PMC7446761 DOI: 10.11606/s1518-8787.2020054002179] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2019] [Accepted: 02/18/2020] [Indexed: 01/05/2023] Open
Abstract
OBJECTIVE To characterize recent HIV infections among newly diagnosed men who have sex with men and transgender women in Tijuana. METHODS Limiting Antigen (LAg)-Avidity testing was performed to detect recent HIV infection within a cohort of newly-diagnosed men who have sex with men and transgender women in Tijuana. Logistic regression was used to determine characteristics associated with recent infection. A partial transmission network was inferred using HIV-1 pol sequences. Tamura-Nei 93 genetic distances were measured between all pairs of sequences, and the network was constructed by inferring putative transmission links (genetic distances ≤ 1.5%). We assessed whether recent infection was associated with clustering within the inferred network. RESULTS Recent infection was detected in 11% (22/194) of newly-diagnosed participants. Out of the participants with sequence data, 60% (9/15) with recent infection clustered compared with 31% (43/139) with chronic infection. Two recent infections belonged to the same cluster. In adjusted analyses, recent infection was associated with years of residence in Tijuana (OR = 1.5; 95%CI 1.01-1.09), cocaine use (past month) (OR = 8.50; 95%CI 1.99-28.17), and ever experiencing sexual abuse (OR = 2.85; 95%CI 1.03-7.85). DISCUSSION A total of 11% of men newly diagnosed with HIV who have sex with men and transgender women in Tijuana were recently infected. The general lack of clustering between participants with recent infection suggests continued onward HIV transmission rather than an outbreak within a particular cluster.

Perceived barriers to pre-exposure prophylaxis use and the role of syndemic factors among female sex workers in the Mexico-United States border region: a latent class analysis. AIDS Care 2020; 32:557-566. [PMID: 31163975 PMCID: PMC6891112 DOI: 10.1080/09540121.2019.1626338] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2018] [Accepted: 05/29/2019] [Indexed: 12/17/2022]
Abstract
Female sex workers (FSWs) experience syndemic factors (e.g., polydrug use, hazardous alcohol consumption, client-perpetrated violence, depression, and sexually transmitted infections) that often heighten vulnerability to HIV and limit healthcare utilization. We hypothesized that syndemic factors will limit FSWs' uptake of pre-exposure prophylaxis (PrEP). From 2016 to 2017, 295 HIV-negative FSWs were enrolled in a behavioral HIV prevention trial in Tijuana and Ciudad Juarez, Mexico, underwent STI testing, and completed surveys on syndemic factors and perceived barriers to PrEP use. Syndemic scores (0-5) were calculated by summing syndemic factors. Latent class analysis (LCA) was used to identify homogeneous classes with respect to perceived barriers to PrEP use. We identified four classes: (1) perceived healthcare access barriers (8.3%), (2) perceived financial barriers (18.7%), (3) high level of perceived barriers (19.9%), and (4) low level of perceived barriers (53.0%) to PrEP use. Those experiencing three (adjusted odds ratio [aOR] = 3.63, 95% confidence interval [CI] = 1.24-10.67) and four or five (aOR = 6.30, 95% CI = 1.70-23.35) syndemic factors had a higher odds of membership in the class characterized by a high level of perceived barriers than in the class characterized by a low level of perceived barriers. Addressing syndemic factors may maximize PrEP's impact among FSWs along Mexico's northern border.

Stigma and Web-Based Sex Seeking Among Men Who Have Sex With Men and Transgender Women in Tijuana, Mexico: Cross-Sectional Study. JMIR Public Health Surveill 2020; 6:e14803. [PMID: 32031963 PMCID: PMC7055757 DOI: 10.2196/14803] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2019] [Revised: 09/20/2019] [Accepted: 11/15/2019] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Stigma toward sexual and gender minorities is an important structural driver of HIV epidemics among men who have sex with men (MSM) and transgender women (TW) globally. Sex-seeking websites and apps are popular among MSM and TW. Interventions delivered via Web-based sex-seeking platforms may be particularly effective for engaging MSM and TW in HIV prevention and treatment services in settings with widespread stigma toward these vulnerable populations. OBJECTIVE To assess the potential utility of this approach, the objectives of our study were to determine the prevalence of Web-based sex seeking and examine the effect of factors that shape or are influenced by stigma toward sexual and gender minorities on Web-based sex seeking among MSM and TW in Tijuana, Mexico. METHODS From 2015 to 2018, 529 MSM and 32 TW were recruited through venue-based and respondent-driven sampling. Interviewer-administered surveys collected information on Web-based sex seeking (past 4 months) and factors that shape or are influenced by stigma toward sexual and gender minorities (among MSM and TW: traditional machismo, internalized stigma related to same-sex sexual behavior or gender identity, and outness related to same-sex sexual behavior or gender identity; among MSM only: sexual orientation and history of discrimination related to same-sex sexual behavior). A total of 5 separate multivariable logistic regression models were used to examine the effect of each stigma measure on Web-based sex seeking. RESULTS A total of 29.4% (165/561) of our sample reported seeking sex partners on the Web. Web-based sex seeking was negatively associated with greater endorsement of traditional machismo values (adjusted odds ratio [AOR] 0.36, 95% CI 0.19 to 0.69) and greater levels of internalized stigma (AOR 0.96, 95% CI 0.94 to 0.99). Web-based sex seeking was positively associated with identifying as gay (AOR 2.13, 95% CI 1.36 to 3.33), greater outness (AOR 1.17, 95% CI 1.06 to 1.28), and a history of discrimination (AOR 1.83, 95% CI 1.08 to 3.08). CONCLUSIONS Web-based sex-seeking is relatively common among MSM and TW in Tijuana, suggesting that it may be feasible to leverage Web-based sex-seeking platforms to engage these vulnerable populations in HIV prevention and treatment services. However, HIV interventions delivered through Web-based sex-seeking platforms may have limited reach among those most affected by stigma toward sexual and gender minorities (ie, those who express greater endorsement of traditional machismo values, greater levels of internalized stigma, lesser outness, and nongay identification), given that within our sample they were least likely to seek sex on the Web.

Perceived barriers to pre-exposure prophylaxis use among HIV-negative men who have sex with men in Tijuana, Mexico: A latent class analysis. PLoS One 2019; 14:e0221558. [PMID: 31437243 PMCID: PMC6705824 DOI: 10.1371/journal.pone.0221558] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2019] [Accepted: 08/09/2019] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND Given the slow uptake of PrEP among cisgender men who have sex with men (MSM) in high-income countries, efforts to roll-out PrEP in low- and middle-income countries (LMIC) should address barriers to PrEP use to facilitate its more rapid uptake. To inform PrEP programs in LMIC, we examined patterns of perceived barriers to PrEP use among HIV-negative MSM in Tijuana, Mexico. METHODS From 03/2016-09/2017, 364 MSM completed interviewer-administered surveys assessing perceived barriers to PrEP use across 4 domains: PrEP attribute, individual, interpersonal, and structural. Latent class analysis was performed to identify distinct classes with respect to perceived barriers to PrEP use. Multinomial logistic regression was used to identify factors associated with class membership. RESULTS We identified three classes characterized by (1) high levels of perceived barriers across domains (12%), (2) low levels of perceived barriers across domains (43%), and (3) perceived PrEP attribute barriers (i.e., side-effects and cost) (45%). Membership in the high level of perceived barriers class (vs. the low level of perceived barriers class) was positively associated with having a history of incarceration (AOR: 2.44; 95% CI: 1.04, 5.73) and negatively associated with more social support (AOR: 0.99; 95% CI: 0.98, 1.00). Membership in the perceived PrEP attribute barriers class was positively associated with having seen a healthcare provider in the past year (AOR: 2.78; 95% CI: 1.41, 5.45) and negatively associated with having any HIV-positive or status unknown partners (AOR: 0.56; 95% CI: 0.31, 1.01). CONCLUSIONS Since most participants were in either the low level of perceived barriers class or the perceived PrEP attribute barriers class, future PrEP uptake may be high among MSM in Tijuana. However, these findings suggest that achieving sufficient PrEP uptake and adherence among MSM in Tijuana may require a range of comprehensive HIV prevention interventions.

Abstract
Understanding the relationship between cognitive and behavioral processes and long-term behavior change is critical to developing behavior change maintenance interventions. We examined the relationship between cognitive and behavioral safer sex maintenance strategies and condomless vaginal/anal sex with clients among female sex workers (FSWs) in Mexico. We hypothesized a moderating effect of hazardous alcohol use, such that the relationship between the use of safer sex maintenance strategies and condomless sex would be weaker among FSWs who meet criteria for hazardous alcohol consumption. Data were gathered from 602 FSWs enrolled in a sexual risk reduction intervention with a text messaging maintenance component. Seven cognitive and behavioral strategies purported to be critical in sustaining long-term behavior change were measured (e.g., maintenance self-efficacy). The relationship between FSWs’ use of safer sex maintenance strategies and condomless vaginal/anal sex with clients was moderated by hazardous alcohol consumption. The association was weaker among FSWs who met criteria for hazardous alcohol consumption. Among FSWs who met criteria for hazardous alcohol consumption, maintenance self-efficacy was associated with fewer condomless sex acts with clients ( b = −0.35, p < .001). Among FSWs who did not meet criteria for hazardous alcohol consumption, recovery self-efficacy ( b = −0.21, p < .05) and self-monitoring ( b = −0.34, p < .001) were associated with fewer acts of condomless sex. Results indicate the importance of examining the multidimensional nature of safer sex maintenance strategies and of exploring subgroup differences in their associations with behavioral outcomes. Interventions that address safer sex maintenance strategies in the context of alcohol treatment should be developed for this subgroup of FSWs.

Abstract
Stressors that arise in parenting are likely to have an adverse impact on the psychological well-being of female sex workers (FSWs), particularly in low- to middle-income countries (LMIC). This study examined the association between maternal role strain and depressive symptoms among 426 FSW mothers with dependent-age children (aged < 18 years) in Tijuana and Cd. Juarez, Mexico (2016-2017). Four dimensions of maternal role strain (e.g., child emotional and behavioral problems) were examined in relation to maternal depressive symptoms. We also investigated whether the relationship between maternal role strain and depressive symptoms was modified by venue of sex work. Compared to indoor/establishment-based FSWs, street-based FSWs reported significantly more child-related financial strain. In multiple regression analysis, having more depressive symptoms was associated with identifying as a street-based FSW, greater use of drugs, lower emotional support, more child-related financial strain and more emotional and behavioral problems in children. A significant interaction was identified such that the association between maternal role strain and depressive symptoms was stronger for indoor/establishment-based compared to street-based FSWs. These findings suggest the need to address parenting strain and type of sex work venue in the development of counseling programs to improve the mental health of FSWs in LMIC.

Abstract
OBJECTIVE To identify correlates of HIV/STI prevalence among 13 cities with varying sizes of female sex worker (FSW) populations and municipal characteristics in Mexico. MATERIALS AND METHODS FSWs underwent interviews and testing for HIV, syphilis, gonorrhea and chlamydia. Logistic regression explored variations in HIV/STI prevalence. RESULTS Among FSWs (n=1 092), prevalence across 13 sites was: HIV: 0.4% (range: 0%-1.4%): syphilis: 7.8% (range: 0%-17.2%); chlamydia: 15.3% (range: 5.7%-32.2%); gonorrhea:2.9% (range 0%-13.8%), and any HIV/STI: 23% (range: 9.9%- 46%). Municipalities with high human development scores and a lower municipal marginalization index had higher odds of combined HIV/STI prevalence. After controlling for sitespecific variability in municipal characteristics, greater risk of HIV/STIs was associated with lower education, having a spouse diagnosed or treated for an STI, unaffordability of condoms, and having non-Mexican clients. CONCLUSIONS Prevalence of HIV/STIs varies across Mexican municipalities indicating the need for surveillance to identify hotspots for targeted resource allocation.

Impact of time perspectives on texting intervention to reduce HIV/STI transmission among female sex workers in Tijuana and Ciudad Juarez, Mexico. J Behav Med 2019; 42:111-127. [PMID: 29987740 PMCID: PMC6326895 DOI: 10.1007/s10865-018-9948-1] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2018] [Accepted: 07/03/2018] [Indexed: 12/13/2022]
Abstract
Text messages may sustain post-counseling gains in behavioral improvements and reduce HIV/STI incidence. However, their effectiveness may depend on the messages' time perspective and characteristics of the individual. We evaluated the impact of time perspective on a text messaging intervention designed to maintain improvements in safer sex practices among drug-using and non-drug-using female sex workers (FSWs) in Tijuana (n = 141) and Cd. Juarez (n = 129), Mexico. FSWs received the efficacious Mujer Segura intervention, and were randomized to receive safer sex maintenance text messages with either a short-term or future-oriented time perspective. The outcome was HIV/STI incidence rate over 6-month follow-up. In Tijuana, combined HIV/STI incidence density was lower among FSWs in the FUTURE group (31.67 per 100 py) compared to women in the SHORT-TERM group (62.40 per 100 py). Conversely, in Cd. Juarez, HIV/STI incidence density was lower (although non-significant) among FSWs in the SHORT-TERM group (19.80 per 100 py) compared to those in the FUTURE group (35.05 per 100 py). These findings suggest that future-oriented text messages may sustain post-counseling improvements in sexual risk behavior among FSWs, but findings may vary by FSWs' characteristics (e.g., drug use), and by region and context.

Factors associated with program effectiveness in the implementation of a sexual risk reduction intervention for female sex workers across Mexico: Results from a randomized trial. PLoS One 2018; 13:e0201954. [PMID: 30204761 PMCID: PMC6133277 DOI: 10.1371/journal.pone.0201954] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2017] [Accepted: 07/18/2018] [Indexed: 11/24/2022] Open
Abstract
OBJECTIVE The overall aim of this paper is to examine effectiveness of an evidence-based intervention in community settings, and the factors associated with effectiveness. Limited research in the area of HIV prevention has focused on evaluating intervention program effectiveness in real-world settings. METHODS We implemented an efficacious theory-based sexual risk reduction intervention for female sex workers (FSW) called Mujer Segura across 13 different clinics in 13 sites across Mexico. The overall design was a cluster randomized Type I design simultaneously testing intervention program effectiveness with an observational study of implementation factors. We aimed to examine the effectiveness of Mujer Segura at reducing HIV/STI incidence among FSW participants at each site, and to examine the client-, provider-, organization-, and structure-related factors associated with program effectiveness. RESULTS We found lower HIV/STI incidence density in the intervention relative to the control group in 5 sites we labeled as "program effective sites," but not in 8 sites we labeled as "program ineffective sites." Using generalized estimating equations controlling for site and computed mean difference effect sizes, we examined statistically and practically significant differences, respectively, between the two groups of sites along various client-, provider-, organization-, and structure-related characteristics. Results indicated that client-level HIV/AIDS related knowledge, and proficiency and engagement in the organizational social context were associated with program effectiveness. CONCLUSIONS Enormous resources are required to systematically and adequately test the role of multilevel factors on program effectiveness. We successfully implemented Mujer Segura in 13 sites in Mexico. Results suggest that other measures may need to be included in future implementation studies than the ones included here. We were able to point to a few specific factors that should be targeted to increase effectiveness of similar evidence-based programs in low- and other middle-income countries like Mexico.

Abstract
Methamphetamine use poses increased risk for HIV and other sexually transmitted infections. There is robust evidence that methamphetamine use increases sexual risk behavior, like condomless sex, primarily among men who have sex with men but also among heterosexual women and men. Gender differences have been found among women and men who use meth, and there is a high degree of interconnectedness between meth use, depression, and condomless sex. The aims of the current study are to evaluate the efficacy of a theory-based, tri-focal intervention designed to reduce depression, meth use, and condomless sex among women and men, and to examine gender as a moderator of efficacy. A total of 432 HIV-negative women and men who use meth participated in a two-arm randomized controlled trial and completed baseline and follow-up assessments at 4, 8, and 12 months. We used latent growth curve modeling techniques to analyze the data. Results showed that while all participants exhibited reductions in depression, meth use, and condomless sex, the intervention and comparison groups did not differ in changes over time. However, we did find a significant gender moderation effect, such that among men, those in the intervention arm reported greater reductions in meth use relative to those in the comparison group; reduced meth use was associated with reduced condomless sex, but not depression. In contrast, women in the intervention condition did not differ from women in the comparison condition in changes in any of the three outcome variables. Interventions targeting heterosexual women and men who use meth must be gender-specific, and take into account the unique vulnerabilities and experiences of women, including the perceived positive aspects of using meth, gendered power dynamics, higher depression, and violence.

Abstract
To assess the potential uptake of HIV pre-exposure prophylaxis (PrEP) products among female sex workers (FSWs) vulnerable to HIV infection, we examined the influence of product attributes on willingness to use products among 271 HIV-negative FSWs in Tijuana and Ciudad Juarez, Mexico (2016-2017). Via five-point Likert scale ratings, participants indicated their willingness to use hypothetical products with six attributes: formulation (pill, gel, liquid, or ring), frequency of use (daily, on-demand, or monthly), cost per use (10 or 200 pesos), effectiveness (40% or 80%), side effects (none or mild), and access point (healthcare clinic or non-governmental organization). Conjoint analysis was used to determine the impact of attributes on product ratings and identify preferred product attributes. Multinomial logistic regression was used to identify factors associated with formulation preferences. In both cities, formulation and frequency of use had the greatest impact on ratings. Participants in Ciudad Juarez indicated a strong preference for oral pills, whereas participants in Tijuana indicated roughly equal preferences for oral pills and vaginal gels. Monthly product use was preferred in both cities. Compared to preferring oral pills (38%), preferring vaginal gels (28%) was associated with practicing vaginal lubrication (adjusted odds ratio = 2.08; 95% confidence interval: 1.07-4.04). Oral PrEP may be acceptable to many FSWs in Tijuana and Ciudad Juarez; however, continued development of behaviorally-congruent vaginal PrEP products may also facilitate uptake and ensure sufficient coverage.

Abstract
Background To assess the potential acceptability and inform the development of behaviorally-congruent vaginal douche- or gel-based HIV pre-exposure prophylaxis (PrEP) products, we examined vaginal washing and lubrication practices among female sex workers (FSWs) in Tijuana and Ciudad Juarez, two northern Mexico cities bordering the United States (US). Methods Two hundred and ninety-five HIV-negative FSWs (145 Tijuana; 150 Ciudad Juarez) enrolled in a behavioral HIV prevention intervention trial completed surveys assessing vaginal washing and lubrication practices, as well as motivators and barriers to performing each practice. Logistic regression was used to identify potential predictors of each practice in the past month. Results In the past month, vaginal washing was performed by 56 and 22% of FSWs in Tijuana and Ciudad Juarez (p < 0.0001), respectively, while vaginal lubrication was performed by 64 and 45% of FSWs in Tijuana and Ciudad Juarez (p = 0.001), respectively. Vaginal washing was positively associated with living in Tijuana (adjusted odds ratio [AOR] = 4.35, 95% confidence interval [CI]: 2.60–7.30), older age (AOR = 1.04 per year, 95% CI: 1.01–1.06), and vaginal lubrication (AOR = 2.99, 95% CI: 1.67–5.35), while it was negatively associated with being born in the same state as the study site (AOR = 0.50, 95% CI: 0.31–0.82), earning a monthly income ≥3500 pesos (AOR = 0.53, 95% CI: 0.28–1.00), and hazardous alcohol consumption (AOR = 0.56, 95% CI: 0.33–0.95). Vaginal lubrication was positively associated with living in Tijuana (AOR = 2.21, 95% CI: 1.37–3.54) and vaginal washing (AOR = 2.91, 95% CI: 1.64–5.18), while it was negatively associated with being born in the same state as the study site (AOR = 0.47, 95% CI: 0.29–0.75). Conclusions The moderate and high prevalence of vaginal washing and lubrication, respectively, suggest behaviorally-congruent, multi-purpose, vaginal douche- and gel-based PrEP products that simultaneously address FSWs’ needs and prevent HIV infection may be acceptable to many FSWs along the Mexico-US border. Future product development and implementation should also consider the link between vaginal washing and lubrication to ensure existing practices do not undermine vaginal PrEP product effectiveness.

Abstract
Undiagnosed HIV infection is common among men who have sex with men (MSM) and transgender women (TW) in Latin America. We examined uptake of a partner notification (PN) model among MSM and TW in Tijuana, Mexico. Forty-six HIV-positive MSM/TW enrolled as index patients, and reported 132 MSM/TW sexual partners for PN. Of notified partners (90/132), 39% declined eligibility screening or participation, 39% tested for HIV, and of those 28% were newly-diagnosed HIV-positive. Partners who were seen by the index patient more than once in the past 4 months and those who primarily had sex with the index patient in one of their homes were more likely to be notified via PN (76% vs. 50%; p = 0.01 and 86% vs. 64%, p = 0.02, respectively). Lower than expected PN uptake was associated with problems identifying index patients, obtaining reliable partner contact information, and engaging notified partners.

Abstract
Men's misogynistic attitudes (i.e., dislike or contempt for women) have been shown to be associated with men's perpetration of physical/sexual violence against women and poor health outcomes for women. However, these attitudes have rarely been examined for their influence on men's own health. This paper examines the socio-demographic, substance use, and mental health correlates of misogynistic attitudes among a binational sample of men (n=400) in Tijuana, Mexico with high-risk substance use and sexual behaviors. We used a 6-item scale to measure misogynistic attitudes (α = .72), which was developed specifically for this context. We used descriptive statistics to describe our sample population and the extent to which they hold misogynistic attitudes. Then, using misogynistic attitudes as our dependent variable, we conducted bivariate linear regression and multivariable linear regression to examine the relationship between these attitudes and socio-demographic characteristics, substance use behaviors (i.e., use of alcohol, marijuana, heroin, methamphetamines, cocaine), and mental health (i.e., depression, self-esteem). In the multivariable model, we found significant relationships between misogynistic attitudes and education level (t = -4.34, p < 0.01), heroin use in the past 4 months (t = 2.50, p = 0.01), and depressive symptoms (t = 3.37, p < 0.01). These findings suggest that misogynistic attitudes are linked to poor health outcomes for men and future research needs to further explore the temporality of these relationships and identify strategies for reducing men's misogynistic attitudes with the ultimate aim of improving the health and well-being of both women and men.

Abstract
The Substance Abuse, Violence, and HIV/AIDS (SAVA) syndemic model describes how the confluence of the three epidemics of substance abuse, violence, and HIV risk work synergistically to create excess burden among populations. We sought to identify risk factors associated with recent intimate partner violence (IPV) victimization among heterosexual methamphetamine (meth)-using men (n = 108) and women (n = 122) enrolled in FASTLANE-II, an HIV behavioral intervention in San Diego, CA. Women and men reported high rates of physical-only (women: 20%; men: 18%) and sexual (women: 25%; men: 23%) IPV. Multinomial regression analysis revealed that individuals who reported lower social support and individuals who reported a greater likelihood of engaging in risky sexual behaviors while high on meth were more likely to report IPV versus no IPV. Women who reported a greater likelihood of engaging in risky sexual behaviors while high on meth were 1.58 times more likely to report physical-only IPV versus no IPV, while men who reported similar behaviors were 1.15 times more likely to report physical-only IPV versus no IPV. Our findings highlight the influence of interpersonal factors on IPV. This research supports further study on gender-specific risk/protective factors and the development of gender-specific interventions targeting the SAVA syndemic among meth users.

Correlates of condomless anal sex among men who have sex with men (MSM) in Tijuana, Mexico: The role of public sex venues. PLoS One 2017; 12:e0186814. [PMID: 29065132 PMCID: PMC5655432 DOI: 10.1371/journal.pone.0186814] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2017] [Accepted: 10/09/2017] [Indexed: 11/17/2022] Open
Abstract
Condomless anal sex between male partners is the primary risk factor for HIV transmission among men who have sex with men (MSM). Correlates of condomless anal sex have been well-studied in developed countries, but they have received less attention in lower-to-middle income countries (LMIC), where MSM are often subject to stigma, discrimination, intolerance, and even the criminalization of same sex behavior. In Mexico, a LMIC where traditional views on homosexuality are common, HIV prevalence among MSM is high (16.9%), yet little research has been conducted on the correlates of condomless anal sex in this high-risk population. The present study examined correlates of condomless anal sex among 201 MSM recruited in Tijuana, Mexico, with a focus on the role of public sex venues in relation to sexual risk behavior. Eligibility requirements were: biologically male, 18 years of age or older, resident of Tijuana, and self-reported anal or oral sex with a male partner in the past year. Participants completed an interviewer-administered, demographic and psychosocial survey, and were tested for HIV and syphilis. A hierarchical multiple linear regression model was tested to identify correlates of condomless anal sex. Thirty-eight percent of participants (N = 76) reported condomless anal sex with a male partner in the past 2 months. Higher levels of condomless anal sex were associated with higher levels of depressive symptoms, greater sexual compulsivity, and more frequent seeking out of sex partners in a public venue in the past 2 months. In view of these findings, we recommend the development of multi-level, “combination” interventions, which in the Mexican context should include enhanced condom promotion and distribution, improved availability and access to mental health treatment and counseling services, and expanded HIV/STI testing in public venues.

Correlates of Sexual Violence Among Men Who Have Sex With Men in Tijuana, Mexico. ARCHIVES OF SEXUAL BEHAVIOR 2017; 46:1011-1023.

Abstract
Sexual violence among men who have sex with men (MSM) is prevalent in developing countries and is associated with increased HIV/STI risk. Despite high HIV prevalence (20 %) among MSM in Tijuana, Mexico, little attention has been paid to the occurrence of sexual violence in this high-risk group. The present study used a syndemic conditions framework to examine correlates of sexual violence victimization in a sample of 201 MSM surveyed in Tijuana, Mexico during 2012 and 2013. Participants were recruited through respondent-driven sampling and underwent a 2-h baseline interview and testing for HIV and syphilis. Sexual violence was defined as any incident during the past year in which the participant had been raped, sexually molested, or sexually harassed. The majority of participants self-identified as gay or bisexual, had never married, were employed, and had a high school education or greater. The average age was 29.7 years. Thirty-nine percent reported sexual violence in the past year. A hierarchical multiple linear regression model predicting more experiences of sexual violence was tested. In a final model, a higher number of experiences of sexual violence was associated with a history of childhood sexual abuse, more adult experiences of homophobia, more depression and hostility symptoms, and not living with a spouse or steady partner. The findings from this study support a model of co-occurring psychosocial factors that increase the likelihood of sexual violence experiences among MSM. Multi-level approaches to the prevention of childhood and adult experiences of sexual violence and homophobia are needed to avert the development of adverse mental and physical health outcomes associated with sexual violence victimization.

Does physical education influence eye-hand coordination? The Lifestyles of our Kids intervention study. Scand J Med Sci Sports 2016; 27:1824-1832.

Abstract
In Australian government-funded primary schools, the responsibility for physical education (PE) falls mainly on general classroom teachers, many of whom possess limited PE training. This study sought to examine the impact of specialist-taught PE on eye-hand coordination (EHC) development. In this 4-year cluster-randomized intervention, participants were 187 boys and 172 girls initially in grade 2 in 29 primary schools, where no school employed university-trained specialist PE teachers. In 13 (intervention) schools, specialist PE teachers conducted 268 PE classes (two 45-minute sessions/wk) from grade 2 to grade 6. The intervention was based on traditional PE educational objectives, including fundamental motor skills, but did not specifically focus on EHC. The remaining 16 (control) schools continued with common-practice PE taught by general classroom teachers (30-60 min/wk). EHC was measured by a ball throw and wall-rebound catch test and recorded at ages 8, 10, and 12 (SD 0.3) at ends of grades 2, 4, and 6, respectively. There was steady yearly improvement of EHC in both groups, but no evidence of any intervention effect in boys (P=.88) or girls (P=.20). The introduction of specialist-taught PE during 4 years of primary school did not influence EHC development. Considering evidence that classroom teachers make little contribution to PE in this jurisdiction, together with the steady progression of EHC over the 4 years, other influences such as organized sport, after-school activities, natural development, and parental instruction are conceivably more influential factors in EHC development during primary school years.

Abstract
Female sex workers (FSW) are at high risk of acquiring sexually transmitted infections (STIs), including HIV, and putting their clients and other partners at risk for infection. There is considerable evidence that Social Cognitive Theory (SCT)–based interventions are effective in reducing high-risk sexual behavior among at-risk populations in the United States. However, no studies have been undertaken of such interventions with FSWs in Mexico, where high rates of STIs exist and where sex tourism attracts a large number of American clients. This article describes the development of a culturally relevant sexual risk reduction intervention based on SCT and Theory of Reasoned Action for FSWs in Mexico. The intervention was designed to promote consistent use of condoms with clients. Spanish-speaking counselors used motivational interviewing techniques and skill-building exercises to promote behavior change in a clinic-based sample of FSWs. The authors describe the intervention and provide pilot data that demonstrate the feasibility and benefits of this approach.

Abstract
This study examined correlates of unprotected vaginal and anal sex (UVA) with male clients among female sex workers (FSWs). Baseline data were gathered from 1089 FSWs recruited from 13 cities across Mexico enrolled in an evidence-based sexual risk reduction intervention. We used generalised estimating equations (GEE) to predict total UVA while controlling for the nested structure of the data. Total UVA with clients in the past month was examined in relation to selected sociodemographic, substance-use, and micro- and macro-environmental factors. A greater number of UVA acts was associated with three micro-level environmental factors (i.e. never getting condoms for free, unaffordability of condoms, greater number of clients per month), and three macro-level environmental factors (i.e. lower health and higher education indices, greater population size of city). These findings suggest the development of social and structural approaches to HIV prevention for FSWs in Mexico, including modification of venue-based policies that pressure FSWs to maximise client volume, changes to the work environment that promote availability and affordability of condoms, and improved population health. Moreover, our findings call for the development of context-specific HIV interventions that take into account variations in the sexual risk behaviours and HIV risk environments of FSWs throughout Mexico.

Abstract
OBJECTIVES HIV testing is critical to the delivery of comprehensive HIV prevention and care services, yet coverage of sexual minorities by HIV testing programmes remains insufficient in many low- and middle-income countries, including Mexico. The objective of this study was to identify the prevalence and correlates of HIV testing among men who have sex with men (MSM) in Tijuana, Mexico. METHODS We conducted a cross-sectional study (2012-2013) among 189 MSM recruited via respondent-driven sampling (RDS). RDS-weighted logistic regression was used to identify correlates of prior HIV testing. RESULTS RDS-adjusted prevalence of prior and recent (≤ 12 months) HIV testing was 63.5% (95% CI 51.9% to 73.5%) and 36.8% (95% CI 25.4% to 46.4%), respectively. Prior HIV testing was positively associated with older age (adjusted OR (AOR)=1.09, 95% CI 1.04 to 1.15), being born in Tijuana (AOR=2.68, 95% CI 1.05 to 6.86), higher levels of education (AOR=2.65, 95% CI 1.08 to 6.53), identifying as homosexual or gay (AOR=3.73, 95% CI 1.48 to 9.42), being more 'out' about having sex with men (AOR=1.28, 95% CI:1.02 to 1.62), and a history of sexual abuse (AOR=3.24, 95% CI 1.06 to 9.86). Prior HIV testing was negatively associated with reporting more condomless anal intercourse acts (past 2 months) (AOR=0.95, 95% CI 0.92 to 0.98) and greater internalised homophobia (AOR=0.92, 95% CI 0.86 to 0.99). CONCLUSIONS Our findings indicate an urgent need for expanded HIV testing services for MSM in Tijuana. Innovative, non-stigmatising, confidential HIV testing interventions targeted at young, less educated, migrant and non-gay identifying MSM may facilitate HIV testing and timely linkage to HIV care and treatment within this population.

Abstract
BACKGROUND Globally, client-perpetrated violence against female sex workers (FSWs) has been associated with multiple health-related harms, including high-risk sexual behavior and increased exposure to HIV/STIs. This study examined correlates of client-perpetrated sexual, physical, and economic violence (e.g., robbery) against FSWs in 13 cities throughout Mexico. METHODS FSWs (N = 1,089) who were enrolled in a brief, evidence-based, sexual risk reduction intervention for FSWs (Mujer Segura) were interviewed about their work context, including experiences of violence perpetrated by clients, sexual risk and substance use practices, financial need, and social supports. Three broad categories of factors (sociodemographic, work context, behavioral and social characteristics of FSWs) were examined as correlates of sexual, physical, and economic violence. RESULTS The prevalence of different types of client-perpetrated violence against FSWs in the past 6 months was: sexual (11.7%), physical (11.8%), economic (16.9%), and any violence (22.6%). Greater financial need, self-identification as a street worker, and lower perceived emotional support were independently associated with all three types of violence. Alcohol use before or during sex with clients in the past month was associated with physical and sexual violence. Using drugs before or during sex with clients, injection drug use in the past month, and population size of city were associated with sexual violence only, and FSWs' alcohol use score (AUDIT-C) was associated with economic violence only. CONCLUSIONS Correlates of client-perpetrated violence encompassed sociodemographic, work context, and behavioral and social factors, suggesting that approaches to violence prevention for FSWs must be multi-dimensional. Prevention could involve teaching FSWs strategies for risk avoidance in the workplace (e.g., avoiding use of alcohol with clients), enhancement of FSWs' community-based supports, development of interventions that deliver an anti-violence curriculum to clients, and programs to address FSWs' financial need by increasing their economic opportunities outside of the sex trade.

Abstract
AIMS To describe the prevalence and correlates of hazardous drinking among female sex workers (FSWs) at 13 sites throughout Mexico. METHODS FSWs (N = 1089) who were enrolled in a brief sexual risk reduction intervention (Mujer Segura) were queried about their sexual risk and substance use practices and their work contexts. Participants were classified as hazardous or non-hazardous drinkers based on the Alcohol Use Disorders test (AUDIT-C). Logistic regression models were used to examine individual, contextual, and community-level factors as correlates of hazardous drinking. RESULTS Ninety-two percent of participants reported alcohol consumption in the past month. Among drinkers (N = 1001), 83% met AUDIT-C criteria for hazardous drinking. Factors that were independently associated with hazardous drinking included: drug use in the past month (adjusted odds ratio (AOR) = 3.31; 95% CI 1.29-8.45), being a cigarette smoker (AOR = 1.71; 95% CI 1.13-2.58), being a barmaid or dance hostess (AOR = 3.40; 95% CI 1.95-5.91), alcohol use before or during sex with clients (AOR = 7.78; 95% CI 4.84-12.52), and working in a city with a higher marginalization index (AOR = 1.07; 95% CI 1.04-1.11). CONCLUSIONS Findings support the high prioritization by public health authorities of alcohol prevention and treatment programs for FSWs.

Buffering Syndemic Effects in a Sexual Risk-Reduction Intervention for Male Clients of Female Sex Workers: Results From a Randomized Controlled Trial. Am J Public Health 2015; 105:1866-71.

Abstract
OBJECTIVES We sought to test the efficacy of a sexual risk intervention for male clients of female sex workers (FSWs) and examine whether efficacy was moderated by syndemic risk. METHODS From 2010 to 2014, we conducted a 2-arm randomized controlled trial (60-minute, theory-based, safer sex intervention versus a didactic time-equivalent attention control) that included 400 male clients of FSWs on the US-Mexico border with follow-up at 4, 8, and 12 months. We measured 5 syndemic risk factors, including substance use and depression. Primary outcomes were sexually transmitted infections incidence and total unprotected sex with FSWs. RESULTS Although participants in both groups became safer, there was no significant difference in behavior change between groups. However, baseline syndemic risk moderated intervention efficacy. At baseline, there was a positive association between syndemic risk and unprotected sex. Then at 12 months, longitudinal analyses showed the association depended on intervention participation (B = -0.71; 95% confidence interval [CI] = -1.22, -0.20; P = .007). Among control participants there still existed this modest association (B = 0.36; 95% CI = -0.49, 1.22; P = .09); among intervention participants there was a significant negative association (B = -0.35; 95% CI = -0.63, -0.06; P = .02). CONCLUSION A brief intervention might attenuate syndemic risks among clients of FSWs. Other populations experiencing syndemic problems may also benefit from such programs.

Abstract
Most studies of heterosexual sex risk practices have focused on condomless vaginal sex despite evidence that condomless anal sex has a significantly higher risk of HIV transmission. The present study focused on male clients' anal sex practices with female sex workers (FSWs) in Tijuana, Mexico, where an HIV epidemic is growing among high-risk groups. Logistic regression analyses were used to identify psychosocial and behavioral correlates of anal sex among male clients. Our sample of HIV-negative men (N = 400) was predominantly Latino (87.5 %), born in Mexico (78.8 %), never married (36.8 %) or in a regular or common-law marriage (31.5 %), and employed (62.8 %), with an average age and education of 37.8 and 9.2 years, respectively. Eighty-nine percent identified as heterosexual and 11 % as bisexual. By design, 50 % of the sample resided in Tijuana and the other 50 % in San Diego County. Nearly half (49 %) reported at least one incident of anal sex with a FSW in Tijuana in the past 4 months; of those participants, 85 % reported that one or more of their anal sex acts with FSWs had been without a condom. In a multivariate model, anal sex with a FSW in the past 4 months was associated with bisexual identification, methamphetamine use with FSWs, repeat visits to the same FSW, higher scores on perceived stigma about being a client of FSWs, and sexual compulsivity. Prevention programs are needed that address the behavioral and psychosocial correlates of heterosexual anal sex in order to reduce HIV/STI transmission risk among male clients, FSWs, and their sexual network members.

Abstract
HIV prevention efforts must be comprehensive in their understanding of the factors involved in HIV risk. Male clients, who have received less research attention than female sex workers (FSWs), may experience stigma as a function of purchasing sex. Perceived stigma may be related to poor psychological outcomes, risky psychosexual characteristics, and higher drug and sexual risk behavior among male clients of FSWs. However, perceived stigma of purchasing sex may differ between clients of different ethnic groups. In the present study, we examine the correlates of perceived stigma of purchasing sex among Latino versus non-Latino male clients of FSWs in Tijuana, Mexico. Using time-location sampling, we recruited 375 male clients (323 Latino, 52 non-Latino) in Tijuana who completed a computerized survey on various measures. We measured perceived stigma of purchasing sex using three items we developed for this study. Using linear regression analyses we found that perceived stigma was associated with greater guilt, a greater feeling of escape from everyday life, and more negative condom attitudes among Latino clients. This was not found among non-Latino clients. Features of Latino culture, like machismo, and how they may relate to stigma of purchasing sex are discussed.

[PMID: 25128035 DOI: 10.1016/j.whi.2014.06.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2014] [Revised: 05/25/2014] [Accepted: 06/17/2014] [Indexed: 10/24/2022]
Abstract
BACKGROUND Drug use and partner violence affect older women, yet few studies highlight age-specific HIV risks and prevention strategies. This study compares sexual risk behaviors, condom use attitudes, and HIV knowledge between midlife/older women (ages 45+) and younger women (ages 18-44) reporting methamphetamine use and partner violence in San Diego, California. METHODS Our mixed methods study used themes from a qualitative substudy (n = 18) to inform logistic regression analysis of baseline data from an HIV behavioral intervention trial (n = 154). FINDINGS Age-related qualitative themes included physiologic determinants, HIV knowledge, and "dodging the bullet," referring to a lifetime of uncertainty surrounding HIV serostatus after engaging in unsafe drug and sex practices. Midlife/older age was associated with never being married (24.2% vs. 51.2; p = .03), having less than a high school education/GED (12.1% vs. 34.7%; p = .04), lower condom use self-efficacy (2.87 vs. 3.19; p = .03), lower positive outcome expectancies (1.9 vs. 2.1; p = .04), and lower HIV knowledge (85.3% vs. 89.7%; p = .04); however, sexual risk behaviors were not associated with age group. In the multivariate analysis, midlife/older age remained independently associated with lower condom use self-efficacy (adjusted odds ratio, 0.49; 95% CI, 0.27-0.87) and lower HIV knowledge (adjusted odds ratio, 0.96; 95% CI, 0.93-0.99). CONCLUSIONS Midlife/older methamphetamine-using women with experiences of partner violence present similar sexual risk profiles, but possess different HIV-related knowledge and attitudes toward prevention methods compared with their younger counterparts. Clinicians and public health practitioners can have a positive impact on this overlooked population by assessing HIV risks during routine screenings, encouraging HIV testing, and providing age-appropriate HIV prevention education.

Hazardous drinking and HIV-risk-related behavior among male clients of female sex workers in Tijuana, Mexico. Am J Addict 2014; 23:502-9. [PMID: 25066863 DOI: 10.1111/j.1521-0391.2014.12138.x] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2013] [Revised: 02/14/2014] [Accepted: 04/12/2014] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND AND OBJECTIVES Male clients of female sex workers (FSWs) are at high risk for HIV. Whereas the HIV risks of alcohol use are well understood, less is known about hazardous alcohol use among male clients of FSWs, particularly in Mexico. We sought to identify risk factors for hazardous alcohol use and test associations between hazardous alcohol use and HIV risk behavior among male clients in Tijuana. METHOD Male clients of FSWs in Tijuana (n = 400) completed a quantitative interview in 2008. The AUDIT was used to characterize hazardous alcohol use. Multivariate logistic regression was used to determine independent associations of demographic and HIV risk variables with hazardous alcohol use (vs. non-hazardous). RESULTS Forty percent of our sample met criteria for hazardous alcohol use. Variables independently associated with hazardous drinking were reporting any sexually transmitted infection (STI), having sex with a FSW while under the influence of alcohol, being younger than 36 years of age, living in Tijuana, and ever having been jailed. Hazardous drinkers were less likely ever to have been deported or to have shared injection drugs. DISCUSSION AND CONCLUSIONS Hazardous alcohol use is associated with HIV risk, including engaging in sex with FSWs while intoxicated and having an STI among male clients of FSWs in Tijuana. SCIENTIFIC SIGNIFICANCE We systematically described patterns and correlates of hazardous alcohol use among male clients of FSWs in Tijuana, Mexico. The results suggest that HIV/STI risk reduction interventions must target hazardous alcohol users, and be tailored to address alcohol use.

Correlates of self-efficacy for condom use among male clients of female sex workers in Tijuana, Mexico. ARCHIVES OF SEXUAL BEHAVIOR 2014; 43:719-727. [PMID: 23842786 PMCID: PMC3851585 DOI: 10.1007/s10508-013-0149-2] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/05/2012] [Revised: 03/08/2013] [Accepted: 05/25/2013] [Indexed: 06/02/2023]
Abstract
Male clients of female sex workers (FSWs) in Tijuana, Mexico engage in high levels of unprotected sex. While behavioral change theories posit that self-efficacy predicts condom use, correlates of self-efficacy for condom use remain largely unstudied. We examined these correlates among male clients of FSWs in Tijuana. Eligible male clients were at least 18 years of age, HIV-negative, lived in Tijuana or San Diego, reported unprotected sex with a Tijuana FSW at least once in the past 4 months, and agreed to be treated for sexually transmitted infections (STIs). Participants completed an interviewer-administered questionnaire including demographics, substance use, psychosocial and psychosexual characteristics (e.g., outcome expectancies for negotiation of safer sex, social support, and sexual sensation seeking), and sexual behaviors. Participants also underwent HIV/STI testing. A stepwise hierarchical multiple regression analysis identified correlates of self-efficacy for condom use. Of 393 male clients, median age was 37 years. Participants were mostly Spanish-speaking and employed. Factors independently associated with higher self-efficacy for condom use were higher positive outcome expectancies for negotiation of safer sex, lower sexual sensation seeking scores, and higher social support scores. Both psychosocial and psychosexual factors may influence self-efficacy for condom use among male clients of FSWs. These factors represent central constructs in sociocognitive models that explain behavioral change and could be intervention targets for improving self-efficacy for condom use and, ultimately, safer sex behavior.

Abstract
Female drug dealers have been a neglected population despite their potentially elevated risk for social, legal, family, and psychological health problems. This study examined correlates of drug-dealing behavior in a sample of 209 female methamphetamine users in San Diego, CA. Twenty-five percent of the sample reported dealing methamphetamine in the past 2 months. Women who dealt methamphetamine were significantly more likely than their nondealing counterparts to have started using illicit drugs before the age of 13 years (68 % versus 44.7 %, p = .003); to have been introduced to methamphetamine by a parent (15.1 % versus 5.8 %, p = .037); and to report currently using methamphetamine to stay awake (84.9 % versus 64.7 %, p = .004), enhance self-confidence (62.3 % versus 45.5 %, p = .025), and feel more attractive (54.7 % versus 38.5 %, p = .029). In a multivariate logistic regression, factors independently associated with methamphetamine dealing were: having a spouse or live-in partner (Adjusted Odds Ratio, AOR = 2.89), using methamphetamine with a broader range of types of person (AOR = 1.46), and reporting lower levels of emotional support (AOR = 0.57). These findings suggest that female methamphetamine dealers are in urgent need of access to substance use treatment, therapies to enhance self-worth and emotional support, and family-based substance use prevention interventions for dependent children and those at risk.

Implementation of an efficacious intervention for high risk women in Mexico: protocol for a multi-site randomized trial with a parallel study of organizational factors. Implement Sci 2012; 7:105. [PMID: 23107285 PMCID: PMC3503741 DOI: 10.1186/1748-5908-7-105] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2012] [Accepted: 10/25/2012] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Studies of implementation of efficacious human immunodeficiency virus (HIV) prevention interventions are rare, especially in resource-poor settings, but important, because they have the potential to increase the impact of interventions by improving uptake and sustainability. Few studies have focused on provider and organizational factors that may influence uptake and fidelity to core intervention components. Using a hybrid design, we will study the implementation of an efficacious intervention to reduce sexually transmitted infections (STIs) among female sex workers (FSWs) in 12 cities across Mexico. Our protocol will test a 'train-the-trainer' implementation model for transporting the Mujer Segura (Healthy Woman) intervention into community-based organizations (CBOs). METHODS We have partnered with Mexican Foundation for Family Planning (Mexfam), a non-governmental organization that has CBOs throughout Mexico. At each CBO, trained ethnographers will survey CBO staff on characteristics of their organization and on their attitudes toward their CBO and toward the implementation of evidence-based interventions (EBIs). Then, after CBO staff recruit a sample of 80 eligible FSWs and deliver a standard-care, didactic intervention to 40 women randomly selected from that pool, a Mexfam staff person will be trained in the Mujer Segura intervention and will then train other counselors to deliver Mujer Segura to the 40 remaining participating FSWs. FSW participants will receive a baseline behavioral assessment and be tested for HIV and STIs (syphilis, gonorrhea, and chlamydia); they will be reassessed at six months post-intervention to measure for possible intervention effects. At the same time, both qualitative and quantitative data will be collected on the implementation process, including measures of counselors' fidelity to the intervention model. After data collection at each CBO is complete, the relative efficacy of the Mujer Segura intervention will be analyzed, and across CBOs, correlations will be examined between individual and organizational provider characteristics and intervention efficacy. DISCUSSION This cooperative, bi-national research study will provide critical insights into barriers and facilitating factors associated with implementing interventions in CBOs using the 'train the trainer' model. Our work builds on similar scale-up strategies that have been effective in the United States. This study has the potential to increase our knowledge of the generalizability of such strategies across health issues, national contexts, and organizational contexts. TRIAL REGISTRATION NCT01465607.

Abstract
BACKGROUND While methamphetamine users report high rates of internalized or self-stigma, few studies have examined experiences of stigma (i.e., stigmatization by others) and its correlates. METHODS This study identified correlates of stigma experiences in a sample of 438 HIV-positive men who have sex with men (MSM) who were enrolled in a sexual risk reduction intervention in San Diego, CA. RESULTS Approximately 96% of the sample reported experiences of stigma related to their use of methamphetamine. In multiple regression analysis, experiences of stigma were associated with binge use of methamphetamine, injection drug use, increased anger symptoms, reduced emotional support, and lifetime treatment for methamphetamine use. CONCLUSIONS These findings suggest that experiences of stigma are common among methamphetamine users and that interventions to address this type of stigma and its correlates may offer social, psychological, and health benefits to HIV-positive methamphetamine-using MSM.

Abstract
Nagpur is an industrial hub in Maharashtra, a state in Central India that has the second highest HIV prevalence in the country. Approximately 3000 brothel-based female sex workers (FSWs) are estimated to be working in Nagpur's Ganga-Jamuna red light district. The extent to which brothel madams, known as gharwalis, support HIV/STI prevention for FSWs has not been examined. The present study sought to identify personal, social, and behavioral characteristics of gharwalis in Nagpur as well as enhance our understanding of the gharwali's role in shaping the sexual practices of brothel-based FSWs. Thirty gharwalis participated in a survey that covered personal, social, behavioral, and environmental characteristics. Respondents ranged in age from 29 to 50 years (M = 38.9) and had worked as a gharwali for an average of 5.3 years; 80% had no formal education, 43% had never married, and 30% were divorced or separated, and 93% earned money from their own sex work. Gharwalis managed an average of 4.2 FSWs (range 2-10). Overall, gharwalis reported positive attitudes toward condoms, promoted use of condoms by their FSWs with clients, taught FSWs how to use condoms, knew where to obtain condoms for free, and required HIV testing for their FSWs; however, levels of HIV prevention knowledge were low. Gharwalis also reported providing a range of support services to FSWs who lived in their brothels, including shelter, protection from drunk and aggressive clients and police, emotional support, caring and love, and health care. These data suggest the feasibility of involving gharwalis in brothel-based HIV prevention programs.

Abstract
OBJECTIVE The methamphetamine epidemic in the United States involves a large number of men and women with dependent-age children. However, we know little about the parenting strains experienced by methamphetamine-using mothers and fathers and the relationship of these parenting strains to mental health outcomes, specifically depressive symptoms. METHOD The primary goal of this study was to examine five dimensions of parental role strain in relation to depressive symptoms in a sample of 180 methamphetamine-using parents of dependent-age children in San Diego, CA. Dimensions of parental role strain included child emotional and behavioral problems, child physical health problems, child-related financial strain, interpersonal conflict involving children, and intrapsychic strain related to children. RESULTS Methamphetamineusing mothers reported significantly more child-related emotional and behavioral problems compared with methamphetamine-using fathers (7.9 vs. 6.8; t = 2.5, p < .05). In multiple regression analysis, higher Beck depression scores were associated with being a mother (β = .186, p < .05), having more children younger than 18 years old (β = .165, p < .05), less emotional support (β = -.230, p < .01), and higher scores on intrapsychic parental role strain related to children (β = .288, p < .01). CONCLUSIONS These findings suggest the importance of considering the multidimensional nature of parenting strain in the development of drug treatment and counseling programs for methamphetamine-using parents.

Abstract
Although rates of methamphetamine use continue to increase throughout the United States, little is known about the individuals who sell methamphetamine at the street level. This exploratory study examined the prevalence and correlates of drug-dealing behavior in a sample of 404 heterosexually identified methamphetamine users who were participants in a sexual risk reduction intervention in San Diego, California. Twenty-nine percent of participants (N = 116) reported "dealing" methamphetamine in the past 2 months. In a multivariate logistic regression, methamphetamine dealing was associated with being male (OR = 1.99; 95% CI 1.16-3.39), younger age (OR = 1.87 per year; 95% CI 1.10-3.17), more frequent use of methamphetamine (OR = 2.69; 95% CI 1.59-4.57), injecting methamphetamine (OR = 3.10; 95% CI 1.79-5.37), and higher hostility scores (OR = 1.07 per unit increase; 95% CI 1.01-1.13). These characteristics, particularly intensity of drug use and hostility, may be associated with greater resistance to drug treatment and lower success in treatment programs.

Abstract
This study used cross-sectional data to examine perceived risk behavior of social network members as a correlate of AIDS risk behavior in a sample of 230 heterosexually-identified, methamphetamine (meth) users. The highest ratings of risk behavior within participants' social networks were associated with meth use and non-use of condoms. Friends received the highest ratings in terms of overall perceived involvement in drug and sexual risk behaviors. In a multivariate analysis, perceived risk behavior of others, social norms, and attitudes toward AIDS preventive behaviors were significantly associated with intentions to always use condoms. Strategies for addressing negative social influences in the context of sexual risk reduction interventions are described.

Abstract
While many studies have examined correlates of trading sex for money, few have examined factors associated with exclusive trading of sex for drugs. We identified sociodemographic, behavioral, and psychological correlates of trading sex for methamphetamine in a sample of HIV-negative heterosexual men and women who were enrolled in a sexual risk reduction intervention in San Diego, California. Of 342 participants, 26% overall (21% of males and 31% of females) reported trading sex for methamphetamine in the past two months. Multiple logistic regression analysis revealed that recently trading sex for methamphetamine was independently associated with being female, homeless, binging on methamphetamine, sexual victimization in the past two months, engaging in anal sex 24 or more times in the past two months, and higher sexual compulsivity scores. Effective interventions for this high-risk population should consider gender-focused counseling for sexual abuse, motivational enhancement therapy, social-cognitive skills training, as well as enhanced access and utilization of social services, including drug treatment.

HIV risk profiles among HIV-positive, methamphetamine-using men who have sex with both men and women. ARCHIVES OF SEXUAL BEHAVIOR 2011; 40:793-801.

Abstract
This study examined demographic characteristics, sexual risk behaviors, sexual beliefs, and substance use patterns in HIV-positive, methamphetamine-using men who have sex with both men and women (MSMW) (n = 50) as compared to men who have sex with men only (MSM) (n = 150). Separate logistic regressions were conducted to predict group membership. In the final model, of 12 variables, eight were independently associated with group membership. Factors independently associated with MSMW were acquiring HIV through injection drug use, being an injection drug user, using hallucinogens, using crack, being less likely to have sex at a bathhouse, being less likely to be the receptive partner when high on methamphetamine, having greater intentions to use condoms for oral sex, and having more negative attitudes about HIV disclosure. These results suggest that, among HIV-positive methamphetamine users, MSMW differ significantly from MSM in terms of their HIV risk behaviors. Studies of gay men and HIV often also include bisexual men, grouping them all together as MSM, which may obscure important differences between MSMW and MSM. It is important that future studies consider MSM and MSMW separately in order to expand our knowledge about differential HIV prevention needs for both groups. This study showed that there were important differences in primary and secondary prevention needs of MSM and MSMW. These findings have implications for both primary and secondary HIV prevention among these high-risk populations.

Abstract
Drug assertiveness skills have been demonstrated to be effective in reducing substance use behaviors among patients with alcohol or heroin use disorders. This study examined the association between drug assertiveness and methamphetamine use, psychological factors, and sexual risk behaviors in a sample of 250 HIV-positive men who have sex with men enrolled in a safer sex intervention in San Diego, CA. Less assertiveness in turning down drugs was associated with greater frequency and larger amounts of methamphetamine use, lower self-esteem, higher scores on a measure of sexual sensation seeking, and greater attendance at risky sexual venues. These data suggest that drug assertiveness training should be incorporated into drug abuse treatment programs and other risk reduction interventions for methamphetamine users.

How important are venue-based HIV risks among male clients of female sex workers? A mixed methods analysis of the risk environment in nightlife venues in Tijuana, Mexico.

Abstract
In 2008, 400 males ≥18 years old who paid or traded for sex with a female sex worker (FSW) in Tijuana, Mexico, in the past 4 months completed surveys and HIV/STI testing; 30 also completed qualitative interviews. To analyze environmental sources of HIV vulnerability among male clients of FSWs in Tijuana, we used mixed methods to investigate correlates of clients who met FSWs in nightlife venues and clients' perspectives on venue-based HIV risk. Logistic regression identified micro-level correlates of meeting FSWs in nightlife venues, which were triangulated with clients' narratives regarding macro-level influences. In a multivariate model, offering increased pay for unprotected sex and binge drinking were micro-level factors that were independently associated with meeting FSWs in nightlife venues versus other places. In qualitative interviews, clients characterized nightlife venues as high risk due to the following macro-level features: social norms dictating heavy alcohol consumption; economic exploitation by establishment owners; and poor enforcement of sex work regulations in nightlife venues. Structural interventions in nightlife venues are needed to address venue-based risks.

Abstract
Male clients of female sex workers (FSWs) may act as a bridge to the general population contributing to the spread of HIV and other sexually transmitted infections (STIs) in the USA and Mexico. This study used cross-sectional data to identify psychosexual and social-cognitive factors associated with sexual risk behavior in a bi-national sample of 300 male clients of FSWs recruited in Tijuana, Mexico from June to October 2008. In a multiple regression analysis, the number of unprotected vaginal sex acts with FSWs was associated with higher sexual compulsivity scores, lower self-efficacy for condom use, greater use of illicit drugs, and more financial need. Behavioral interventions are urgently needed to assist clients of FSWs in reducing high-risk behaviors in an effort to prevent the spread of HIV/STIs in this high-risk population and their sexual partners.

Abstract
This study examined attitudes about condoms as a moderator of the relationship between methamphetamine use and sexual risk behavior in a sample of 297 HIV-positive, methamphetamine-using men who have sex with men (MSM). To test for a moderating effect of attitudes towards condoms, an interaction term was included in multiple regression analysis along with age, income, negative condom attitudes, frequency of methamphetamine use, and Beck depression score. A post hoc analysis was conducted to determine the relations between methamphetamine use and unprotected sex for persons with more vs. less negative attitudes toward condoms. These analyses indicated that when individuals had more negative attitudes toward condoms, the relation between methamphetamine frequency and unprotected sex was significant, while among participants with less negative attitudes toward condoms, no significant association was found. Addressing methamphetamine-using MSM's attitudes about condoms can serve as a form of harm reduction for those who are not yet ready or willing to discontinue methamphetamine use.

Abstract
BACKGROUND Previous research among drug-using men who have sex with men (MSM) indicates that trading sex for methamphetamine may be common. OBJECTIVES This study identified background characteristics, substance use variables, contextual factors, and sexual risk behaviors associated with trading sex for methamphetamine in a sample of HIV-positive MSM. Baseline data were gathered from 155 participants who were enrolled in a sexual risk-reduction intervention. Logistic regression was used to compare MSM who traded sex for methamphetamine with men who did not. RESULTS Forty-three percent of the sample reported trading sex for methamphetamine in the past 2 months. Trading sex for methamphetamine was associated with being a binge user, homelessness, having an income of less than $20,000 per year, being less assertive at turning down drugs, engaging in more anal sex without a condom, and seeking out risky sex partners when high on methamphetamine. CONCLUSION AND SCIENTIFIC SIGNIFICANCE These data suggest that the trading of sex for methamphetamine may be a primary source of new HIV infections within and outside of the MSM community, necessitating targeted interventions with this vulnerable subgroup.

Abstract
Retrospective reports of children's relationships with their parents have been associated with increased risk for depressive symptoms in adulthood. This study examined four dimensions of the current mother-child relationship (affection, criticism, over-involvement, conflict) in relation to depressive symptoms in a sample of 270 HIV-positive men who have sex with men (MSM). Depressive symptoms were positively associated with overt conflict or disagreement with mothers and perceived over-involvement by mothers, and inversely related to frequency of contact with mothers. These findings suggest that clinicians who treat HIV-positive methamphetamine-using MSM with depressive symptoms should evaluate issues in the mother-son relationship and consider family-based therapies as an adjunct to treatment.

Abstract
Identifying psychosocial factors associated with sexual risk behavior among methamphetamine users is essential to enhancing HIV and sexually transmitted infection prevention. This study examined the relationship between positive and negative life events and sexual risk behavior in a sample of 100 HIV-negative, heterosexually identified, methamphetamine-using men and women. Negative life event categories included death of a significant other, negative health event involving self or significant other, and child custody or visitation issues. Categories of positive life events included birth or pregnancy involving self or significant other, a positive relationship event, and a positive life change. Multivariate analyses demonstrated that negative life events were positively associated with total number of unprotected sex acts, whereas positive life events were not associated with sexual risk taking. Also, amount of methamphetamine used did not moderate the relationship between life events and sexual risk behavior. These data support future research to identify underlying mechanisms that link negative life events to sexual risk taking in this high-risk population.

Abstract
Methamphetamine (MA) use has been found to be associated with increased risk of HIV and sexually transmitted infections (STI) among men having sex with men, but it is unknown whether those who inject MA are at greater risk for these infections than those who administer MA by other routes. Furthermore, comparable data from heterosexual MA users are lacking. We investigated whether the HIV and STI risks of male and female heterosexual MA users who inject MA differ from those of comparable users who do not inject. Between 2001 and 2005, we interviewed 452 HIV-negative men and women aged 18 and older who had recently used MA and engaged in unprotected sex. Their mean age was 36.6 years; 68% were male; ethnicity was 49.4% Caucasian, 26.8% African-American, and 12.8% Hispanic. Logistic regression identified factors associated with injecting MA. Compared to non-IDU, IDU were more likely to: be Caucasian; be homeless; have used MA for a longer period and used more grams of MA in the last 30 days; have a history of felony conviction; and report a recent STI. HIV and STI prevention interventions should be tailored according to MA users' method of administration.

Abstract
BACKGROUND Despite increased awareness and attention towards methamphetamine (MA) use among men who have sex with men (MSM), few studies have examined behaviors and effects of MA use among heterosexual populations. OBJECTIVE To learn whether behaviors and effects of MA use among heterosexuals differ according to gender. METHODS We examined gender differences in sociodemographic characteristics, drug use practices, sexual behaviors, and consequences and motivations for MA use among 452 HIV-negative MA users (306 men, 146 women) who had engaged in unprotected sex and used MA in the previous two months. RESULTS Females in the sample were younger and more likely to be married, to have been diagnosed with an STI in the last two months, and to report having been introduced to MA by a sexual partner. Women were also more likely to experience depressive symptoms and to report using MA "to lose weight." Men were more likely to engage in sex marathons while high on MA and to use MA "to enhance sexual pleasure." CONCLUSION These differences suggest the importance of crafting gender-specific intervention messages, and they may contribute to identifying individuals at risk for initiating MA use. SCIENTIFIC SIGNIFICANCE Our findings contribute to our knowledge of gender differences in behaviors and effects of MA use among heterosexuals. Future studies would benefit from collection of longitudinal data (to assess causal relationships) and use of a control group (to distinguish correlates of MA use from those of drug use in general).
