RESUMEN

Studies of parents' online safety concerns typically centre on information privacy and on worries over unknown third parties preying on children, whereas investigations into youth perspectives on online safety have found young people to focus on threats to safety or reputation by known individuals. The case of youth who are themselves parents raises questions regarding how these differing perspectives are negotiated by individuals who are in dual roles as youth and parents. Using interview and ethnographic observation data from the longitudinal Young Parent Study in British Columbia, Canada, this analysis investigates social media and online safety practices of 113 young parents. Online safety concerns of young parents in this study focused on personal safety, their children's online privacy and image management. These concerns reflect their dual roles, integrating youth image and information management concerns with parental concerns over the safety and information privacy of their own children.

RESUMEN

Population health information interventions (PHIIs) use information in efforts to promote health. PHIIs may push information to a target audience (communication), pull information from the public (surveillance), or combine both in a bidirectional intervention. Although PHIIs have often been framed as non-invasive and ethically innocuous, in reality they may be intrusive into people's lives, affecting not only their health but their senses of security, respect, and self-determination. Ethical acceptability of PHIIs may have impacts on intervention effectiveness, potentially giving rise to unintended consequences. This article examines push, pull, and bidirectional PHIIs using empirical data from an ethnographic study of young mothers in Greater Vancouver, Canada. Data were collected from October 2013 to December 2014 via naturalistic observation and individual interviews with 37 young mothers ages 16-22. Transcribed interviews and field notes were analyzed using inductive qualitative thematic analysis. Both push and pull interventions were experienced as non-neutral by the target population, and implementation factors on a structural and individual scale affected intervention ethics and effectiveness. Based on our findings, we suggest that careful ethical consideration be applied to use of PHIIs as health promotion tools. Advancing the 'ethics of PHIIs' will benefit from empirical data that is informed by information and computer science theory and methods. Information technologies, digital health promotion services, and integrated surveillance programs reflect important areas for investigation in terms of their effects and ethics. Health promotion researchers, practitioners, and ethicists should explore these across contexts and populations.

RESUMEN

BACKGROUND: Online health services are a rapidly growing aspect of public health provision, including testing for sexually transmitted and other blood-borne infections (STBBI). Generally, healthcare providers, policymakers, and clients imbue online approaches with great positive potential (e.g., encouraging clients' agency; providing cost-effective services to more clients). However, the promise of online health services may vary across contexts and be perceived in negative or ambiguous ways (e.g., risks to 'gold standard' care provision; loss of provider control over an intervention; uncertainty related to budget implications). This study examines attitudes and perceptions regarding the development of a novel online STBBI testing service in Vancouver, Canada. We examine the perceptions about the intervention's potential by interviewing practitioners and planners who were engaged in the development and initial implementation of this testing service. METHODS: We conducted in-depth interviews with 37 healthcare providers, administrators, policymakers, and community-based service providers engaged in the design and launch of the new online STBBI testing service. We also conducted observations during planning and implementation meetings for the new service. Thematic analysis techniques were employed to identify codes and broader discursive themes across the interview transcripts and observation notes. RESULTS: Some study participants expressed concern that the potential popularity of the new testing service might increase demand on existing sexual health services or become fiscally unsustainable. However, most participants regarded the new service as having the potential to improve STBBI testing in several ways, including reducing waiting times, enhancing privacy and confidentiality, appealing to more tech-savvy sub-populations, optimizing the redistribution of demands on face-to-face service provision, and providing patient-centred technology to empower clients to seek testing. CONCLUSIONS: Participants perceived this online STBBI testing service to have the potential to improve sexual health care provision. But, they also anticipated actions-and-reactions, revealing a need to monitor ongoing implementation dynamics. They also identified the larger, potentially system-transforming dimension of the new technology, which enables new system drivers (consumers) and reduces the amount of control health care providers have over online STBBI testing compared to conventional in-person testing.

RESUMEN

BACKGROUND: The burden of HCV among those living with HIV remains a major public health challenge. We aimed to characterize trends in healthcare-related visits (HRV) of people living with HIV (PLW-HIV) and those living with HIV and HCV (PLW-HIV/HCV), in British Columbia (BC), and to identify risk factors associated with the highest HRV rates over time. METHODS: Eligible individuals, recruited from the BC Seek and Treat for Optimal Prevention of HIV/AIDS population-based retrospective cohort (N = 3955), were ≥ 18 years old, first started combination antiretroviral therapy (ART) between 01/01/2000-31/12/2013, and were followed for ≥6 months until 31/12/2014. The main outcome was HRV rate. The main exposure was HIV/HCV co-infection status. We built a confounder non-linear mixed effects model, adjusting for several demographic and time-dependent factors. RESULTS: HRV rates have decreased since 2000 in both groups. The overall age-sex standardized HRV rate (per person-year) among PLW-HIV and PLW-HIV/HCV was 21.11 (95% CI 20.96-21.25) and 41.69 (95% CI 41.51-41.88), respectively. The excess in HRV in the co-infected group was associated with late presentation for ART, history of injection drug use, sub-optimal ART adherence and a higher number of comorbidities. The adjusted HRV rate ratio for PLW-HIV/HCV in comparison to PLW-HIV was 1.18 (95% CI 1.13-1.24). CONCLUSIONS: Although HRV rates have decreased over time in both groups, PLW-HIV/HCV had 18% higher HRV than those only living with HIV. Our results highlight several modifiable risk factors that could be targeted as potential means to minimize the disease burden of this population and of the healthcare system.

RESUMEN

PURPOSE: To examine the extent to which sexual identity disparities in mental health outcomes (anxiety disorder, mood disorder, anxiety-mood disorder, and co-occurring anxiety or mood disorder and heavy drinking) are mediated by life stress or moderated by a sense of community belonging. METHODS: This study pooled data from a large, national, multi-year sample of Canadians aged 18-59 years, who self-identified as lesbian, gay, bisexual, or heterosexual (N = 222,548). A series of stratified binary mediation models were fitted. Significance of the indirect effect was determined by using bootstrapping to obtain standard errors and confidence intervals. RESULTS: Sexual minority (versus heterosexual) respondents were significantly more likely to describe their lives as stressful, their sense of community belonging as weak, and had significantly greater odds of the negative mental health outcomes. Perceived life stress partially mediated the effects of sexual identity on the mental health outcomes. The differences between the mediated effects for the gay/lesbian and bisexual subgroups were statistically significant (all p < 0.05). When stratified by sense of community belonging, life stress mediated the relationship with mood disorders for the gay/lesbian group, where a strong sense of community belonging was associated with greater odds of mood disorders for gay/lesbian versus heterosexual respondents. CONCLUSIONS: These mediation and moderated mediation models provide further evidence for a social patterning of the mental health disparities experienced by sexual minorities in Canada.

RESUMEN

As routine HIV testing approaches are implemented to enhance participation rates in HIV testing, it is often widely believed that these approaches are socially and ethically justifiable given the underlying assumption that these practices will result in the widespread reduction of HIV-related stigma. Nonetheless, a variety of empirical and theoretical gaps on how HIV testing practices may impact on HIV stigma remain, raising questions about the social underpinnings of the public health rationale. We draw on 50 interviews with 18-24 year-old men to determine how HIV-related stigma is experienced differentially across subgroups of young men in relation to both voluntary and routine testing practices. The men's experiences with routine testing highlight how (mis)interpretations of universal, routine testing practices may serve to (unintentionally) burden disadvantaged subgroups of men; however, when these practices are adequately explicated, the universal dimension of a routine offer greatly diminished these concerns. These findings also show that, under the right conditions, a routine offer can provide transformative opportunities for individuals to reconceptualise their expectations over HIV and HIV-related stigma.

RESUMEN

BACKGROUND: Heavy episodic drinking (HED) is associated with sexual risk behavior and HIV seroconversion among men who have sex with men (MSM), yet few studies have examined heavy drinking typologies in this population. METHODS: We analyzed data from 4,075 HIV-uninfected MSM (aged 16 to 88) participating in EXPLORE, a 48-month behavioral intervention trial, to determine the patterns and predictors of HED trajectories. HED was defined as the number of days in which ≥5 alcohol drinks were consumed in the past 6 months. Longitudinal group-based mixture models were used to identify HED trajectories, and multinomial logistic regression was used to determine correlates of membership in each group. RESULTS: We identified 5 distinct HED trajectories: nonheavy drinkers (31.9%); infrequent heavy drinkers (i.e., <10 heavy drinking days per 6-month period, 54.3%); regular heavy drinkers (30 to 45 heavy drinking days per 6 months, 8.4%); drinkers who increased HED over time (average 33 days in the past 6 months to 77 days at end of follow-up, 3.6%); and very frequent heavy drinkers (>100 days per 6 months, 1.7%). Intervention arm did not predict drinking trajectory patterns. Younger age, self-identifying as white, lower educational attainment, depressive symptoms, and stimulant use were associated with reporting heavier drinking trajectories. Compared to nonheavy drinkers, participants who increased HED more often experienced a history of childhood sexual abuse (CSA). Over the study period, depressive symptomatology increased significantly among very frequent heavy drinkers. CONCLUSIONS: Socioeconomic factors, substance use, depression, and CSA were associated with heavier drinking patterns among MSM. Multicomponent interventions to reduce HED should seek to mitigate the adverse impacts of low educational attainment, depression, and early traumatic life events on the initiation, continuation, or escalation of frequent HED among MSM.

RESUMEN

There is little information on the private lives of women engaged in sex work, particularly how power dynamics within intimate relationships may affect intimate partner violence (IPV). Using baseline data of sex workers enrolled in a longitudinal cohort, "An Evaluation of Sex Workers' Health Access" (AESHA), the present study examined the association between sexual relationship power and IPV among sex workers in non-commercial partnerships in Vancouver, Canada. Pulweritz's Sexual Relationship Power Scale (SRPS) and The World Health Organization (WHO) Intimate Partner Violence against Women Scale (Version9.9) were used. Bivariable and multivariable logistic regression techniques were used to investigate the potential confounding effect of sexual relationship power on IPV among sex workers. Adjusted odds ratios (AOR) and 95% confidence intervals (CIs) were reported. Of 510 sex workers, 257 (50.4%) reported having an non-commercial intimate partner and were included in this analysis. In the past 6 months, 84 (32.7%) sex workers reported IPV (physical, sexual or emotional). The median age was 32 years, 39.3% were of Aboriginal ancestry, and 27.6% were migrants. After controlling for known confounders (e.g., age, Aboriginal ancestry, migrant status, childhood trauma, non-injection drug use), low relationship power was independently associated with 4.19 increased odds (95% CI: 1.93-9.10) and medium relationship power was associated 1.95 increased odds (95% CI: 0.89-4.25) of IPV. This analysis highlights how reduced control over sexual-decision making is plays a critical role in IPV among sex workers, and calls for innovation and inclusive programming tailored to sex workers and their non-commercial intimate partnerships.

RESUMEN

BACKGROUND: The prevalence and correlates of mood disorders among people who self-identify as lesbian, gay or bisexual (LGB) are not well understood. Therefore, the current analysis was undertaken to estimate the prevalence and correlates of self-reported mood disorders among a nationally representative sample of Canadian adults (ages 18 to 59 years). Stratified analyses by age and sex were also performed. METHODS: Using data from the 2007-2008 Canadian Community Health Survey, logistic regression techniques were used to determine whether sexual orientation was associated with self-reported mood disorders. RESULTS: Among respondents who identified as LGB, 17.1% self-reported having a current mood disorder while 6.9% of heterosexuals reported having a current mood disorder. After adjusting for potential confounders, LGB-respondents remained more likely to report mood disorder as compared to heterosexual respondents (AOR: 2.93; 95% CI: 2.55-3.37). Gay and bisexual males were at elevated odds of reporting mood disorders (3.48; 95% CI: 2.81-4.31), compared to heterosexual males. Young LGB respondents (ages 18-29) had higher odds (3.75; 95% CI: 2.96-4.74), compared to same-age heterosexuals. CONCLUSIONS: These results demonstrate elevated prevalence of mood disorders among LGB survey respondents compared to heterosexual respondents. Interventions and programming are needed to promote the mental health and well being of people who identify as LGB, especially those who belong to particular subgroups (e.g., men who are gay or bisexual; young people who are LGB).

RESUMEN

Sexual health and sexually transmitted infection (STI) testing is typically portrayed as a women's issue amid men's estrangement from healthcare services. While the underreporting of men's STIs has been linked to masculinities, little is known about how women interpret and respond to heterosexual men's sexual health practices. The findings drawn from this qualitative study of 34 young women reveal how femininities can be complicit in sustaining, as well as being critical of and disrupting masculine discourses that affirm sexual pleasure and resistance to health help-seeking as men's patriarchal privileges. Our analysis revealed three patterns: looking after the man's libido refers to women's emphasised femininity whereby the man's preference for unprotected sex and reticence to be tested for STIs was accommodated. Negotiating the stronger sex refers to ambivalent femininities, in which participants strategically resist, cooperate and comply with men's sexual health practices. Rejecting the patriarchal double standard that celebrates men as 'studs' and subordinates women as 'sluts' for embodying similar sexual practices reflects protest femininities. Overall, the findings reveal that conventional heterosexual gender relations, in which hegemonic masculinity is accommodated by women who align to emphasised femininity, continues to direct many participants' expectations around men's sexual health and STI testing.

RESUMEN

Sexually transmitted infection testing rates among young men remain low, and their disengagement from sexual health services has been linked to enactments of masculinity that prohibit or truncate discussions of sexual health. Understanding how men align with multiple masculinities is therefore important for tailoring interventions that appropriately respond to their needs. We draw on 32 in-depth interviews with 15-24-year-old men to explore the discourses that facilitate or shut down sexual health communication with peers and sex partners. We employ a critical discourse analysis to explore how men's conversations about sexual health are constituted by masculine hierarchies (such as the ways in which masculinities influence men's ability to construct or challenge and contest dominant discourses about sexual health). Men's conversations about sexual health focused primarily around their sexual encounters - something frequently referred to as 'guy talk'. Also described were situations whereby participants employed a discourse of 'manning up' to (i) exert power over others with disregard for potential repercussions and (ii) deploy power to affirm and reify their own hyper-masculine identities, while using their personal (masculine) power to help others (who are subordinate in the social ordering of men). By better understanding how masculine discourses are employed by men, their sexual health needs can be advanced.

RESUMEN

Web-based sexual-health promotion efforts often utilise reverse discourse - the acknowledgement and rejection of shame associated with stigmatised terms - both to challenge judgments about 'risky' behaviours (e.g., casual sex) and to appeal to young people. This study examines the use of reverse discourse in Internet-based sexual-health promotion and analyses young people's perspectives on this approach. During in-depth interviews and focus groups with young people (aged 15-24), participants shared their perspectives on written (e.g., clinical language; colloquial language) and visual (e.g., generic, stock images; sexualised images) depictions of sexual-health topics on the websites. More explicit styles elicited negative responses from young people in terms of perceived appeal, trust and quality of websites. Negative social mores were associated with some of the more explicit portrayals of young people's sexual lives on the websites, revealing how reverse discourse re-stigmatises young people by re-emphasising young people's sexual activity as inherently risky or immoral. Reverse discourse was perceived to have negative effects on the saliency and credibility of online sexual-health information. We discuss the theoretical basis for the operationalisation of reverse discourse in this context, and discuss the importance of considering sociotechnical aspects of Internet-based sexual-health interventions.

RESUMEN

Injection drug users (IDU) who use methamphetamine (MA) are at an increased risk of HIV infection due to engagement in injection-related risk behavior including syringe sharing. In this cohort study of young IDU aged 18-30, we investigated the relationship between injection MA use and syringe sharing, and whether difficulty accessing sterile syringes mediated this association. Behavioral questionnaires were completed by 384 IDU in Vancouver, Canada between October 2005 and May 2008. Generalized estimating equations were used to estimate direct and indirect effects. The median age of participants was 24 (IQR: 22-27) and 214 (55.7%) were male. Injecting MA was independently associated with syringe sharing. Mediation analyses revealed that difficulty accessing sterile syringes partially mediated the association between injecting MA and syringe sharing. Interventions to reduce syringe sharing among young methamphetamine injectors must address social and structural barriers to accessing HIV prevention programs.

RESUMEN

BACKGROUND: High rates of HIV infection among women of reproductive age have dramatic consequences for personal and public health. Prophylaxis during sexual intercourse in the form of condoms has been the most effective way to prevent both STI and HIV transmission among people living with HIV. OBJECTIVES: To investigate the effectiveness of behavioral interventions in promoting condom use among women living with HIV. SEARCH STRATEGY: We conducted a comprehensive literature search in several scientific databases, clinical trials databases, conference proceedings, and conference websites to identify studies produced between 1980 and May 2010 that met our selection criteria. SELECTION CRITERIA: Studies were included in the analysis if they conducted a randomized controlled trial that examined the effects of behavioral interventions on condom use among HIV-positive women; considered at least one HIV-related behavioral outcome (e.g., reported protected anal, vaginal, or oral sex) or biological outcome (e.g., acquisition of STIs); and one follow-up assessment three months or more after the intervention. Studies were assessed irregardless of langauge or publication status. DATA COLLECTION AND ANALYSIS: We used random effects models to summarize odds ratios (ORs) that compared intervention and control groups with respect to a dichotomous outcome (consistent versus inconsistent condom use). We used funnel plots to examine publication bias and a χ(2) statistic to test for heterogeneity. The methodological and evidence quality was evaluated through risk of bias criteria and the GRADE system, respectively. MAIN RESULTS: Five primary studies that collectively researched a total of 725 women living with HIV were analysed. When compared to standard care or minimal HIV support intervention, meta-analysis showed that behavioral interventions had no effect on increasing condom use among HIV-positive women. This finding was consistent at various follow-up meetings (3, 6, and 12-months) as well as over the entire 12-month follow-up period (OR= 0.82; 95% CI 0.65-1.04; p=0.11). Only one study presented adequate data to analyze the relationship between behavioral interventions and STI incidence. Studies included in this analysis demonstrated low risk of bias based on the risk of bias criteria. However, sample size was considered inadequate across all studies. AUTHORS' CONCLUSIONS: Meta-analysis shows that behavioral interventions have little effect on increasing condom use among HIV-positive women. However, these findings should be used with caution since results were based on a few small trials that were targeted specifically towards HIV-positive women. To decrease sexual transmission of HIV among this population, we recommend interventions that combine condom promotion, family planning provision and counselling, and efforts to reduce viral loads among HIV-positive women and their partners (e.g., HAART treatment provision). New research is needed to address the needs of HIV-positive women, including an assessment of the impact of interventions that combine safer sexual behavior and harm reduction approaches.

RESUMEN

BACKGROUND: Methamphetamine (MA) use continues to be a major public health concern in many urban settings. We sought to assess potential relationships between MA use and individual, social, and structural HIV vulnerabilities among sexual minority (lesbian, gay, bisexual or transgendered) drug users. METHODS: Beginning in 2005 and ending in 2008, 2109 drug users were enrolled into one of three cohort studies in Vancouver, Canada. We analysed longitudinal data from all self-identified sexual minority participants (n = 248). Logistic regression using generalized estimating equations (GEE) was used to examine the independent correlates of MA use over time. All analyses were stratified by biological sex at birth. RESULTS: At baseline, 104 (7.5%) males and 144 (20.4%) females reported sexual minority status, among whom 64 (62.1%) and 58 (40.3%) reported MA use in the past six months, respectively. Compared to heterosexual participants, sexual minority males (odds ratio [OR] = 3.74, p < 0.001) and females (OR = 1.80, p = 0.003) were more likely to report recent MA use. In multivariate analysis, MA use among sexual minority males was associated with younger age (adjusted odds ratio [AOR] = 0.93 per year older, p = 0.011), Aboriginal ancestry (AOR = 2.59, p = 0.019), injection drug use (AOR = 3.98, p < 0.001), having a legal order or area restriction (i.e., "no-go zone") impact access to services or influence where drugs are used or purchased (AOR = 4.18, p = 0.008), unprotected intercourse (AOR = 1.62, p = 0.048), and increased depressive symptoms (AOR = 1.67, p = 0.044). Among females, MA use was associated with injection drug use (AOR = 2.49, p = 0.002), Downtown South residency (i.e., an area known for drug use) (AOR = 1.60, p = 0.047), and unprotected intercourse with sex trade clients (AOR = 2.62, p = 0.027). CONCLUSIONS: Methamphetamine use was more prevalent among sexual minority males and females and was associated with different sets of HIV risks and vulnerabilities. Our findings suggest that interventions addressing MA-related harms may need to be informed by more nuanced understandings of the intersection between drug use patterns, social and structural HIV vulnerabilities, and gender/sexual identities. In particular, MA-focused prevention and treatment programs tailored to disenfranchised male and female sexual minority youth are recommended.

RESUMEN

The purpose of this study was to determine the incidence and predictors of initiating methamphetamine injection among a cohort of injection drug users (IDU). We conducted a longitudinal analysis of IDU participating in a prospective study between June 2001 and May 2008 in Vancouver, Canada. IDU who had never reported injecting methamphetamine at the study's commencement were eligible. We used Cox proportional hazards models to identify the predictors of initiating methamphetamine injection. The outcome was time to first report of methamphetamine injection. Time-updated independent variables of interest included sociodemographic characteristics, drug use patterns, and social, economic and environmental factors. Of 1317 eligible individuals, the median age was 39.9 and 522 (39.6%) were female. At the study's conclusion, 200 (15.2%) participants had initiated injecting methamphetamine (incidence density: 4.3 per 100 person-years). In multivariate analysis, age (adjusted hazard ratio [aHR]: 0.96 per year older, 95%CI: 0.95-0.98), female sex (aHR: 0.58, 95%CI: 0.41-0.82), sexual abuse (aHR: 1.63, 95%CI: 1.18-2.23), using drugs in Vancouver's drug scene epicentre (aHR: 2.15 95%CI: 1.49-3.10), homelessness (aHR: 1.43, 95%CI: 1.01-2.04), non-injection crack cocaine use (aHR: 2.06, 95%CI: 1.36-3.14), and non-injection methamphetamine use (aHR: 3.69, 95%CI: 2.03-6.70) were associated with initiating methamphetamine injection. We observed a high incidence of methamphetamine initiation, particularly among young IDU, stimulant users, homeless individuals, and those involved in the city's open drug scene. These data should be useful for the development of a broad set of interventions aimed at reducing initiation into methamphetamine injection among IDU.

RESUMEN

Suicide is a critical public health concern globally. Sex workers experience a disproportionate burden of social and health inequities driven by forms of violence, stigma, and criminalization, yet empirical research on suicidality is limited. This study longitudinally investigated the burden and socio-structural correlates of recent suicidality among women sex workers in Vancouver, Canada. Data (2010-2017) were drawn from a community-based, prospective cohort of cis and trans women sex workers across Metro Vancouver. Women completed biannual interviewer-administered questionnaires, and correlates of suicidality in the last 6 months were analyzed using bivariate and multivariable logistic regression with generalized estimating equations (GEE). Of 867 women at baseline, 48% (n = 413) reported lifetime suicidality, 16% (n = 141) reported suicidality in the last 6 months, and 29% reported suicidality at some point during the study. In multivariable analysis, factors independently associated with suicidality included physical/sexual childhood abuse (adjusted odds ratio [AOR]: 2.99; 95% confidence interval [CI] = [1.75, 5.10]), mental health issues (depression/anxiety/posttraumatic stress disorder; AOR = 2.19; 95% CI = [1.63, 2.95]), intimate partner violence (AOR: 2.11; 95% CI = [1.60, 2.80]), physical/sexual client violence (AOR: 1.82; 95% CI = [1.33, 2.50]), and homelessness (AOR: 1.44; 95% CI = [1.10, 1.89]). Older age (AOR: 0.97; 95% CI = [0.95, 0.99]) and higher social cohesion (AOR: 0.88; 95% CI = [0.78, 0.99]) were significantly associated with reduced odds of suicidality. Findings reveal key socio-structural correlates of suicidality among sex workers including experiences of historical and interpersonal violence, trauma/mental health issues, and homelessness. Strengthening social cohesion may have a protective effect on suicidality. Trauma-informed community-led structural interventions tailored to sex workers are urgently needed alongside a legal framework that enables collectivization and connectedness.

RESUMEN

In Canada, STI rates are high and rising, especially amongst young men. Meanwhile, the needs of young men regarding STI testing services are poorly understood, as are the socio-cultural and structural factors that influence young men's sexual health-seeking behaviours. To better understand this phenomenon, we draw on interviews with 45 men (ages 15-25) from British Columbia, Canada. Our research reveals how structural forces (e.g. STI testing procedures) interact with socio-cultural factors (e.g. perceptions of masculinities and feminities) to shape young men's experiences with STI testing. STI testing was characterised as both a potentially sexualised experience (e.g. fears of getting an erection during genital examinations), and as a process where young men experience multiple vulnerabilities associated with exposing the male body in clinical service sites. In response, participants drew on dominant ideals of masculinity to reaffirm their predominately hetero-normative gender identities. Despite growing up in an era where sexual health promotion efforts have been undertaken, participants did not feel they had permission to engage in discussions with other men about sexual health issues. Attending to young men's perspectives on STI testing represents a starting point in reforming our approaches to addressing how socio-cultural and structural factors shape these experiences.

RESUMEN

BACKGROUND: The prevalence of HIV and sexually transmitted infections (STIs) among street-involved youth greatly exceed that of the general adolescent population; however, little is known regarding the structural factors that influence disease transmission risk among this population. METHODS: Between September 2005 and October 2006, 529 street-involved youth were enroled in a prospective cohort known as the At Risk Youth Study (ARYS). We examined structural factors associated with number of sex partners using quasi-Poisson regression and consistent condom use using logistic regression. RESULTS: At baseline, 415 (78.4%) were sexually active, of whom 253 (61.0%) reported multiple sex partners and 288 (69.4%) reported inconsistent condom use in the past six months. In multivariate analysis, self-reported barriers to health services were inversely associated with consistent condom use (adjusted odds ratio [aOR] = 0.52, 95%CI: 0.25 - 1.07). Structural factors that were associated with greater numbers of sex partners included homelessness (adjusted incidence rate ratio [aIRR] = 1.54, 95%CI: 1.11 - 2.14) and having an area restriction that affects access to services (aIRR = 2.32, 95%CI: 1.28 - 4.18). Being searched or detained by the police was significant for males (aIRR = 1.36, 95%CI: 1.02 - 1.81). CONCLUSION: Although limited by its cross-sectional design, our study found several structural factors amenable to policy-level interventions independently associated with sexual risk behaviours. These findings imply that the criminalization and displacement of street-involved youth may increase the likelihood that youth will engage in sexual risk behaviours and exacerbate the negative impact of resultant health outcomes. Moreover, our findings indicate that environmental-structural interventions may help to reduce the burden of these diseases among street youth in urban settings.

RESUMEN

The role that environmental factors play in driving HIV and STI transmission risk among street-involved youth has not been well examined. We examined factors associated with number of sex partners using quasi-Poisson regression and consistent condom use using logistic regression among participants enroled in the At Risk Youth Study (ARYS). Among 529 participants, 253 (47.8%) reported multiple partners while only 127 (24.0%) reported consistent condom use in the past 6 months. Homelessness was inversely associated with consistent condom use (adjusted odds ratio [aOR]=0.47, p=0.008), while unstable housing was positively associated with greater numbers of sex partners (adjusted incidence rate ratio [aIRR]=1.44, p=0.010). These findings indicate the need for interventions which modify environmental factors that drive risk among young street-involved populations.
