A study of HIV seroprevalence in a group of homeless youth in Hollywood, California

Examining HIV Risk and Exchange Sex Among Current and Formerly Homeless Young Adults

This study investigated HIV risk among homeless and formerly homeless young adults by examining risky sex behaviors (e.g., condomless sex, exchange sex, and sex with multiple persons) using 90-day and daily recall methods. Data came from a sample of young adults (aged 18–27) with current (n = 101) or past (n = 109) homelessness experience in Los Angeles, California, recruited between 2017 and 2019. Baseline surveys queried demographics and sexual history. Daily retrospective surveys queried sexual events. Multiple logistic regressions were used to test the effects of demographic characteristics including homelessness history, relationship status, substance use, and sexual history on risky sex outcomes. In this sample, 26% reported never using a condom during anal or vaginal sex in the past 90 days, 5% reported testing positive for HIV, 82% had limited to no knowledge of preexposure prophylaxis, and 8% reported having had exchange sex during a 7-day measurement period, with those experiencing homelessness more likely to report. The study suggests supportive housing can reduce the occurrence of exchange sex but that HIV prevention services are still needed in homeless and housing programs to promote safe sexual practices.

Risk behaviour and access to HIV/AIDS prevention services among formerly homeless young adults living in housing programmes

Young adults who experience homelessness have high rates of sexually transmitted infections (STIs) including HIV. Homelessness services programmes that provide housing to young adults have the capacity to reduce STI risk profiles. This study analysed data from 140 formerly homeless adults who moved into a housing programme in Los Angeles County between the ages of 18 and 25 years to investigate risk behaviour and access to HIV/AIDS prevention services. More than three quarters of participants reported sexual activity (vaginal or anal sex) in the prior 3 months, with 63% reporting any unprotected vaginal or anal sex, 29% reporting unprotected sex with a nonserious partner, 40% reporting multiple partners, and 11% reporting exchange sex. About three quarters reported a past-year HIV test. About half of the sample had never heard of pre-exposure prophylaxis (PrEP), 12% had heard of it but didn't know what it was, 25% reported knowing a little bit, and 15% said they knew a lot about PrEP. Slightly more than 4% of the overall sample reported being HIV positive. These findings suggest that housing programmes may be a prime location to implement HIV prevention services.

Factors Associated With HIV Testing Among Atlanta's Homeless Youth

Homeless youth experience increased risk of contracting HIV, making HIV testing imperative in this population. We analyzed factors associated with HIV testing among homeless youth in Atlanta, Georgia using data from the 2015 Atlanta Youth Count and Needs Assessment. The analysis included 693 homeless youth aged 14-25 years, of whom 88.4% reported ever being tested for HIV, and 74.6% reported being tested within the previous year. Prevalence of ever testing for HIV was significantly higher among youth who reported risk factors for HIV (sexually active, transactional sex, or ever having an STI). Higher prevalence of testing within the last year was significantly associated with experiencing physical abuse or transactional sex. However, reporting ≥ 4 sexual partners or not using condoms were not associated with higher testing. Although testing prevalence among homeless youth was high, homeless youth engaging in certain high risk behaviors could benefit from further promotion of HIV testing.

Feasibility of Assessing Economic and Sexual Risk Behaviors Using Text Message Surveys in African-American Young Adults Experiencing Homelessness and Unemployment: Single-Group Study

Background

Text messages offer the potential to better evaluate HIV behavioral interventions using repeated longitudinal measures at a lower cost and research burden. However, they have been underused in US minority settings.

Objective

This study aims to examine the feasibility of assessing economic and sexual risk behaviors using text message surveys.

Methods

We conducted a single-group study with 17 African-American young adults, aged 18-24 years, who were economically disadvantaged and reported prior unprotected sex. Participants received a text message survey once each week for 5 weeks. The survey contained 14 questions with yes-no and numeric responses on sexual risk behaviors (ie, condomless sex, sex while high or drunk, and sex exchange) and economic behaviors (ie, income, employment, and money spent on HIV services or products). Feasibility measures were the number of participants who responded to the survey in a given week, the number of questions to which a participant responded in each survey, and the number of hours spent from sending a survey to participants to receiving their response in a given week. One discussion group was used to obtain feedback.

Results

Overall, 65% (n=11/17) of the participants responded to at least one text message survey compared with 35% (n=6/17) of the participants who did not respond. The majority (n=7/11, 64%) of the responders were women. The majority (n=4/6, 67%) of nonresponders were men. An average of 7.6 participants (69%) responded in a given week. Response rates among ever responders ranged from 64% to 82% across the study period. The mean number of questions answered each week was 12.6 (SD 2.7; 90% of all questions), ranging from 72% to 100%. An average of 6.4 participants (84%) answered all 14 text message questions in a given week, ranging from 57% to 100%. Participants responded approximately 8.7 hours (SD 10.3) after receiving the survey. Participants were more likely to answer questions related to employment, condomless sex, and discussions with sex partners. Nonresponse or skip was more often used for questions at the end of the survey relating to sex exchange and money spent on HIV prevention services or products. Strengths of the text message survey were convenience, readability, short completion time, having repeated measures over time, and having incentives.

Conclusions

Longitudinal text message surveys may be a valuable tool for assessing HIV-related economic and sexual risk behaviors.

Safer Sex Communication and Sexual Health Behaviors Among a Representative Statewide Sample of Homeless Adolescents

Homeless adolescents are at substantial risk of human immunodeficiency virus (HIV), other sexually transmitted infections (STIs), and unplanned pregnancy; however, little research has assessed factors, such as safer sex communication, that may protect homeless adolescents against these negative outcomes. Using the 2015 North Carolina Youth Risk Behavior Survey (YRBS; unweighted N = 5,486; ages 12 to 18; 5% homeless), we compared homeless adolescents' primary safer sex communication sources (i.e., health care providers, parents, teachers, peers, religious leaders) to housed adolescents' communication sources and assessed how these sources relate to sexual health behaviors, including condom use, HIV testing, and number of sexual partners. Most homeless adolescents (61%), and 46% of housed adolescents reported having questions about sex. Further, twice as many homeless adolescents communicated primarily with health care providers compared to housed adolescents. Importantly, among homeless adolescents, communicating primarily with health care providers or teachers was related to greater likelihood of condom use and communicating primarily with religious leaders was related to greater likelihood of HIV testing. Parent communication was unrelated to homeless adolescents' sexual health behaviors. Last, communicating primarily with peers was associated with reduced likelihood of HIV testing. Having nonparental adult communication sources, including health care providers, teachers, and religious leaders, may be critical for encouraging safer sex behaviors among homeless adolescents.

Sexual risk classes among youth experiencing homelessness: Relation to childhood adversities, current mental symptoms, substance use, and HIV testing

The aim of this study was to determine whether there are meaningful subgroups with different types of sexual risk behaviors among youth experiencing homelessness and examine the associations between potential classes and other risk variables. A latent class analysis was used to identify classes of youth according to sexual risk behaviors and sexual assault. A two-class solution was found to be the best fit for the data-Lower and Higher Risk groups. The Higher Risk class had significantly higher levels of synthetic marijuana and alcohol use, mental health diagnoses, and were more likely to have been tested for HIV than the Lower Risk group. Youth were more likely to be in the Higher Risk group if they were cisgender female or lesbian, gay, bisexual, or questioning (LGBQ). Nearly all youth (10/11) who reported having HIV infection were in the Higher Risk group. The Lower Risk group were sexually active but had lower rates of risk behaviors and sexual assault. Youth who were not sexually active had the lowest rates of marijuana and alcohol use as well as HIV testing. Health and social service providers should be aware of the added risks for stress, mental distress, mental health diagnoses, and substance use among youth who also report higher risk sexual behaviors and treat as needed.

Knowledge and Attitudes About Pre-Exposure Prophylaxis Among Young Adults Experiencing Homelessness in Seven U.S. Cities

PURPOSE

Evidence suggests that young adults experiencing homelessness (YEH) are at elevated risk of HIV compared to housed youth. Given the limited research on pre-exposure prophylaxis (PrEP) awareness among YEH, this study examined their PrEP knowledge and attitudes.

METHODS

Data from a cross-sectional survey among YEH (ages 18-26) (n = 1,427) in seven U.S. cities were used to assess their knowledge and attitudes regarding PrEP to inform HIV prevention efforts.

RESULTS

Participants were primarily male youth of color. The mean age was 20.9years. While 66% felt at risk for HIV, only 14% strongly agreed that they try to protect themselves from getting infected with HIV. Most (84%) were eligible for PrEP based on risk, yet only 29% had knowledge of PrEP. Despite this, 59% reported they were likely/extremely likely to take PrEP. Access to free PrEP (55%), HIV testing (72%), healthcare (68%), and one-on-one (62%), and text messaging support (57%) were rated as very/extremely important for PrEP uptake and adherence.

CONCLUSIONS

The results of this study suggest missed opportunities to prevent new HIV infections among YEH. Efforts to increase PrEP uptake among this population should consider provider- and system-level interventions to increase PrEP awareness, decrease PrEP-associated healthcare costs, improve access to PrEP providers, and provide in-person and text messaging support.

But Everyone is Doing It (Sort of)! Perceived Sexual Risks in the Social Environment and the Impact on Homeless Youth Engagement in Concurrent Sexual Relationships

Although homeless youth are likely to engage in concurrent sexual relationships and doing so can accelerate HIV transmission, the issue of sexual concurrency (i.e., having sexual partnerships that overlap in time) has received scarce attention in this vulnerable population. The literature that exists tends to focus on individuals' characteristics that may be associated with concurrency and overlooks the influence of their social environment. Informed by the risk amplification and abatement model (RAAM), this study explored the association between pro-social and problematic social network connections, and sexual concurrency among homeless youth using drop-in center services (N = 841). Nearly 37% of youth engaged in concurrency. Partially consistent with the RAAM, regression analyses showed that affiliation with more problematic ties (i.e., having more network members who practice concurrency and unprotected sex) was associated with greater sexual concurrency. Programs addressing HIV risk among homeless youth in drop-in centers should consider the role youths' network composition may play in concurrency.

A Youth Participatory Project to Address STIs and HIV among Homeless Youth

The purpose of this study was to conduct a youth participatory action research project to address the disparities in sexually transmitted infection (STI) and HIV rates among homeless youth. Four youth served as co-investigators and cultural informants for the project. The team conducted focus groups (N = 22; ages 16-22) and in-depth interviews (N = 20; ages 18-24) with homeless youth to explore decisions about condomless sex, knowledge of STIs and HIV, health-care access for STI-related services, and perceptions about STI testing. Findings revealed that homeless youth have good general knowledge about STIs, are receptive to STI testing for themselves and their sexual partners, and have heightened concerns about being HIV positive and peers knowing their STI status. Results from the current study could contribute to the development of youth-informed tailored interventions to increase protective sexual behavior, reduce health disparities, and improve access to and the quality of health-care services for homeless youth.

Causes of death among street-connected children and youth in Eldoret, Kenya

BACKGROUND

Street-connected young people carry a disproportionate burden of morbidities, and engage in a variety of practices that may heighten their risk of premature mortality, yet there are currently no reports in the literature on the rates or risk factors for mortality among them, nor on their causes of death. In low- and middle-income countries they are frequently in situations that violate their human rights, likely contributing to their increased burden of morbidities and vulnerability to mortality. We thus sought to describe the number of deaths annually, causes of death, and determine the number of deaths attributable to HIV among street-connected young people aged 0 to 30 years in Eldoret, Kenya.

METHODS

Eldoret, Kenya has approximately 1900 street-connected young people. We collected data on deaths occurring from October 2009 to December 2016 from Moi Teaching and Referral Hospital records, Academic Model Providing Access to Healthcare HIV program records, and utilized verbal autopsies when no records were available. Descriptive analyses were conducted stratified by sex and age category, and frequencies and proportions were calculated to provide an overview of the decedents. We used logistic regression to assess the association between underlying cause of death and sex, while controlling for age and location of death.

RESULTS

In total there were 100-recorded deaths, 66 among males and 34 among females; 37% of were among those aged ≤18 years. HIV/AIDS (37%) was the most common underlying cause of death, followed by assault (36%) and accidents (10%) for all decedents. Among males, the majority of deaths were attributable to assault (49%) and HIV/AIDS (26%), while females primarily died due to HIV/AIDS (59%).

CONCLUSION

Our results demonstrate a high number of deaths due to assault among males and HIV/AIDS among males and females. Our findings demonstrate the need for studies of HIV prevalence and incidence among this population to characterize the burden of HIV, particularly among young women given the higher number of deaths attributed to HIV/AIDS among them. Most deaths were preventable and require the urgent attention of service providers and policymakers to implement programs and services to prevent premature mortality and uphold children's rights.

Predicting Sexual Behaviors Among Homeless Young Adults: Ecological Momentary Assessment Study

BACKGROUND

Homeless youth continue to be disproportionately affected by HIV compared with their housed peers, with prevalence rates as high as 13%. Yet, HIV prevention in this high-risk population has been only marginally effective.

OBJECTIVE

The aim of this study was to use ecological momentary assessments to examine real-time factors to determine the predictors of sexual activity among homeless youth.

METHODS

Youth experiencing homelessness aged between 18 and 24 years were recruited from a drop-in center in Houston, Texas, between August 2015 and May 2016. All the participants received a study-issued mobile phone that prompted brief ecological momentary assessments (EMAs) 5 times a day for 21 days. EMA items assessed near real-time sexual behaviors, cognitions, stress, affect, environmental factors, and environmental circumstances.

RESULTS

Participants (N=66) were predominantly male (41/66, 64%) and black (43/66, 66%) with a median age of 20 years. The mean number of EMAs completed by each participant was 45 out of 105 possible observations. During the study, 70% (46/66) of participants were sexually active and reported condomless sex in 102 of the 137 cases of sexual intercourse (74.5%). In total, 82% (38/46) of the youth who reported having sex during the 3 weeks of data collection also reported engaging in high-risk sexual activities, including having condomless sex (24/46, 53%), having multiple sexual partners on the same day (12/46, 26%), trading sex (7/46, 16%), and sharing needles while injecting drugs (1/46, 3%). Of those, 71% (27/38) were engaged in multiple sexual risk behaviors. The predictive model was based on observations from 66 subjects who reported 137 cases of sexual intercourse over 811 days; sexual orientation, race, mental health, drug use, and sexual urge were included as predictors in the parsimonious generalized linear mixed model selected on the basis of the Akaike information criterion. The estimated odds ratios (ORs) were notable for same-day drug use (OR 2.17, 95% CI 4.48-17.31; P<.001) and sexual urge (OR 1.44, 95% CI 1.60-11.28; P=.004). The performance of the risk estimator was satisfactory, as indicated by the value of 0.834 for the area under the receiver operating characteristic curve.

CONCLUSIONS

Real-time EMA data can be used to predict sexual intercourse among a sample of high-risk, predominately unsheltered homeless youth. Sexual urge and drug use accounts for increased odds of engaging in sexual activity on any given day. Interventions targeting sexual urge and drug use may help predict sexual activity among a population at high risk of HIV.

Current Age, Age at First Sex, Age at First Homelessness, and HIV Risk Perceptions Predict Sexual Risk Behaviors among Sexually Active Homeless Adults

While HIV disproportionately impacts homeless individuals, little is known about the prevalence of HIV risk behaviors in the southwest and how age factors and HIV risk perceptions influence sexual risk behaviors. We conducted a secondary data analysis (n = 460) on sexually active homeless adults from a cross-sectional study of participants (n = 610) recruited from homeless service locations, such as shelters and drop-in centers, in an understudied region of the southwest. Covariate-adjusted logistic regressions were used to assess the impact of age at homelessness onset, current age, age at first sex, and HIV risk perceptions on having condomless sex, new sexual partner(s), and multiple sexual partners (≥4 sexual partners) in the past 12 months. Individuals who first experienced homelessness by age 24 were significantly more likely to report condomless sex and multiple sexual partners in the past year than those who had a later onset of their first episode of homelessness. Individuals who were currently 24 years or younger were more likely to have had condomless sex, new sexual partners, and multiple sexual partners in the past 12 months than those who were 25 years or older. Those who had low perceived HIV risk had lower odds of all three sexual risk behaviors. Social service and healthcare providers should consider a younger age at homelessness onset when targeting HIV prevention services to youth experiencing homelessness.

Are Parental Relationships Always Protective? A Social Network Analysis of Black, Latino, and White Homeless Youth and Sexual Risk-Taking Behaviors

Black and Latino homeless youth are at high risk of HIV, and yet no HIV prevention interventions have been specifically designed for these groups. Given the success of parent-child intervention programs for housed Black and Latino youth, this study examined parental relationships that could be leveraged for future HIV prevention efforts targeting minority homeless youth, specifically the associations among presence of parents in social networks, parental influence, and parental support. A convenience sample of Black, Latino, and White homeless youth (N = 754) was recruited from three drop-in centers in Los Angeles. Participants completed a computerized, self-administered questionnaire and an interviewer-led personal social network interview. Multivariate logistic regression models assessed the association between parental relationships and sexual risk behaviors. Forty-five percent (n = 338) of youth identified a parent in their network. Having at least one parent in their network was significantly associated with decreased odds of using a condom for Black and White youth. Black youth were almost four times more likely to report being tested for HIV if they spoke to their parents about sex, whereas Latino youth were 91 % less likely to report being tested for HIV if they talked with their parents about sex. Black youth who identified a parent as a positive influence (i.e., promoting condom use or discouraging multiple partners) were almost four times more likely to have used a condom during their last sexual encounter. Parent-child HIV prevention interventions targeting homeless youth would benefit from culturally tailored adaptations.

Problem Behaviors of Homeless Youth: A Social Capital Perspective

Homeless youth are one of the most marginalized groups in our society. Many researchers identify much higher levels of various problem behaviors among these youth compared to their non-homeless peers. The current study examined the utility of social capital in predicting problem behaviors among homeless youth. Overall, the theoretically derived social capital variable significantly predicted substance use frequency, sexual risk behavior, depression, delinquent behavior as well as number of days homeless. Thus, social capital was useful in understanding and predicting the current life situation among these youth and may be worthy of further study. Findings suggest that meaningful change should utilize interventions that go beyond the individual and are geared towards modifying the social context of individuals' lives.

Condomless Sex Among Homeless Youth: The Role of Multidimensional Social Norms and Gender

Most studies of condomless sex among homeless youth have focused on peer norms, while excluding other potentially pertinent influences. This study explored how different types of relationships contributed to norms about condomless sex and whether such norms were associated with engagement in condomless sex among homeless youth. Additionally, because recent work has noted gender differences in social networks of male and female homeless youth, gender differences in social network norms of condomless sex were also assessed. Egocentric network data were collected from homeless youth accessing services at two drop-in centers in Los Angeles, CA (N = 976). Multivariate analyses (non-stratified and stratified by gender) assessed associations between descriptive, injunctive, and communicative norms and participants' engagement in condomless sex. Multivariate analyses indicated that perception of peer condom use and communication with sexual partners were significantly associated with not engaging in condomless sex. These relationships, however, varied by gender. Implications for interventions are discussed.

Risk Factors for HIV among Zambian Street Youth

The sub-Saharan African region has been disproportionately affected by Human Immunodeficiency Virus (HIV) and Zambia has one of the highest HIV prevalence rates within this region. Moreover, new incidences of HIV infection are increasing most rapidly among those 15 to 24 years of age. Though young people are at high risk for HIV infection, street youth are even more vulnerable given their exposure to high risk behaviors. The current study examines multiple levels of social influence on HIV infection among 250 street youth in Zambia. Results reveal that though the majority of youth understand what behaviors increase their risk for HIV, youth still hold many misconceptions about HIV/AIDS. Additionally, youth who do not have a home to return to and those who report parental drug misuse were significantly more likely to be HIV positive. This study underscores the need for further education among street youth regarding HIV knowledge.

Exploring Contextual Factors of Youth Homelessness And Sexual Risk Behaviors: A Qualitative Study

CONTEXT

HIV disproportionately affects homeless youth, and interventions to date have had minimal success in reducing sexual risk behaviors in this population. Few qualitative studies have been conducted to provide insight into the influence of homelessness-related factors on sexual risk behaviors.

METHODS

A qualitative study with a quantitative component was conducted with a nonprobability sample of 64 homeless youth aged 14-24; participants were recruited from a variety of venues in Houston between October 2013 and March 2014. Thirteen focus group discussions were conducted; thematic analysis was used to identify themes related to HIV risk.

RESULTS

Participants were predominantly black (75%), sheltered (67%) and aged 18 or older (77%). Youth discussed how the circumstances of their homelessness and the struggle to meet their immediate needs led to behaviors and experiences that put them at risk for HIV. Three themes emerged: Homeless youth frequently engage in risky sexual behavior, sometimes as a way to cope with stress; they often trade sex, either voluntarily or involuntarily, for such necessities as money or a place to sleep; and many experienced childhood sexual victimization or have been victimized since becoming homeless. Youth also described how stress, stigma and self-reliance contributed to their involvement in HIV risk behaviors.

CONCLUSIONS

HIV prevention methods that target stress and stigma while respecting youths' self-reliance may help reduce sexual risk behaviors. Further research is needed to determine suitable behavioral change techniques to address these potentially modifiable factors.

Prevalence of sexually transmitted infections including HIV in street-connected adolescents in western Kenya

PURPOSE

The objectives of this study were to characterise the sexual health of street-connected adolescents in Eldoret, Kenya, analyse gender disparity of risks, estimate the prevalence of sexually transmitted infections (STIs), and identify factors associated with STIs.

METHODS

A cross-sectional study of street-connected adolescents ages 12-21 years was conducted in Eldoret, Kenya. Participants were interviewed and screened for Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, herpes simplex virus-2, syphilis and HIV. Descriptive statistics and logistic regression were used to identify factors associated with having any STI.

RESULTS

Of the 200 participants, 81 (41%) were female. 70.4% of females and 60.5% of males reported sexual activity. Of those that participated in at least one STI test, 28% (55/194) had ≥1 positive test, including 56% of females; 14% (28/194) had >1 positive test. Twelve females and zero males (6% overall, 14.8% of females) were HIV positive. Among females, those with HIV infection more frequently reported transactional sex (66.7% vs. 26.1%, p=0.01), drug use (91.7% vs. 56.5%, p=0.02), and reported a prior STI (50.0% vs. 14.7%, p<0.01). Having an adult caregiver was less likely among those with HIV infection (33.3% vs. 71.0%, p=0.04). Transactional sex (AOR 3.02, 95% CI (1.05 to 8.73)), a previous STI (AOR 3.46 95% CI (1.05 to 11.46)) and ≥2 sexual partners (AOR 5.62 95% (1.67 to 18.87)) were associated with having any STI.

CONCLUSIONS

Street-connected adolescents in Eldoret, Kenya are engaged in high-risk sexual behaviours and females in particular have a substantial burden of STIs and HIV. There is a need for STI interventions targeted to street-connected youth.

Homeless youths' HIV risk behaviors with strangers: Investigating the importance of social networks

The purpose of this study was to examine the relationship between homeless youths' HIV risk behaviors with strangers and risk and protective characteristics of their social networks. Data were from the Social Network and Homeless Youth Project. A total of 249 youth aged 14-21 years were interviewed over 15 months in three Midwestern cities in the United States using a systematic sampling strategy. Multivariate results revealed that homeless youth with a greater average number of network members who engaged in more drug risk behaviors and who pressured them into precarious behaviors at least once were more likely to have participated in a greater number of HIV risk behaviors with strangers compared to homeless youth without such network characteristics. Additionally, 19-21 year olds, gay, lesbian, bisexual, and transgendered youth, and those who have run away from home more frequently, participated in more HIV risk behaviors with strangers than 14-18 year olds, heterosexual youth, and those who have run away less often. The final model explained 43 % of the variance in homeless youths' HIV risk behaviors with strangers. It is important to identify network characteristics that are harmful to homeless youth because continued exposure to such networks and participation in dangerous behaviors may result in detrimental outcomes, including contraction of sexually transmitted infections and potentially HIV.

If you provide the test, they will take it: factors associated with HIV/STI Testing in a representative sample of homeless youth in Los Angeles

Homeless youth are at high risk for human immunodeficiency virus (HIV) and other sexually transmitted infections (STI), yet those at greatest risk may never have been tested for HIV or STI. In a probability sample of sexually active homeless youth in Los Angeles (n = 305), this study identifies factors associated with HIV/STI testing status. Most youth (85%) had ever been tested and 47% had been tested in the past 3 months. Recent testing was significantly more likely among youth who self-identified as gay, were Hispanic, injected drugs, and used drop-in centers, and marginally more likely among youth with more depressive symptoms. Drop-in center use mediated the association of injection drug use with HIV/STI testing. HIV/STI testing was unrelated to sexual risk behavior. Drop-in centers can play an important role in facilitating testing, including among injection drug users, but more outreach is needed to encourage testing in other at-risk subgroups.

A family intervention to reduce sexual risk behavior, substance use, and delinquency among newly homeless youth

PURPOSE

We evaluate the efficacy of a short family intervention in reducing sexual risk behavior, drug use, and delinquent behaviors among homeless youth.

METHODS

A randomized controlled trial of 151 families with a homeless adolescent aged 12 to 17 years. Between March 2006 and June 2009, adolescents were recruited from diverse sites in Southern California and were assessed at recruitment (baseline), and at 3, 6, and 12 months later. Families were randomly assigned to an intervention condition with five weekly home-based intervention sessions or a control condition (standard care). Main outcome measures reflect self-reported sexual risk behavior, substance use, and delinquent behaviors over the past 90 days.

RESULTS

Sexual risk behavior (e.g., mean number of partners; p < .001), alcohol use (p = .003), hard drug use (p < .001), and delinquent behaviors (p = .001) decreased significantly more during 12 months in the intervention condition compared with the control condition. Marijuana use, however, significantly increased in the intervention condition compared with the control condition (p < .001).

CONCLUSIONS

An intervention to reengage families of homeless youth has significant benefits in reducing risk over 12 months.

Mobilizing homeless youth for HIV prevention: a social network analysis of the acceptability of a face-to-face and online social networking intervention

The objective of the study is to use social network analysis to examine the acceptability of a youth-led, hybrid face-to-face and online social networking HIV prevention program for homeless youth.Seven peer leaders (PLs) engaged face-to-face homeless youth (F2F) in the creation of digital media projects (e.g. You Tube videos). PL and F2F recruited online youth (OY) to participate in MySpace and Facebook communities where digital media was disseminated and discussed. The resulting social networks were assessed with respect to size, growth, density, relative centrality of positions and homophily of ties. Seven PL, 53 F2F and 103 OY created two large networks. After the first 50 F2F youth participated, online networks entered a rapid growth phase. OY were among the most central youth in these networks. Younger aged persons and females were disproportionately connected to like youth. The program appears highly acceptable to homeless youth. Social network analysis revealed which PL were the most critical to the program and which types of participants (younger youth and females) may require additional outreach efforts in the future.

Risk and protective factors related to HIV-risk behavior: a comparison between HIV-positive and HIV-negative young men who have sex with men

The objective of this study was to assess and compare the prevalence of high-risk sexual behaviors among young HIV-negative (n=8064) and HIV-positive (n=171) men who have sex with men (MSM) on predictors of unprotected anal intercourse (UAI). Using venue-based time-space sampling, 8235 MSM aged 15-25 were anonymously surveyed as a part of the Community Intervention Trial for Youth (CITY). The Project was conducted in 13 communities across the USA from 1999 to 2002. Forty percent of HIV-positive men and 34% of HIV-negative men reported that they had UAI in the previous 3 months. HIV-positive MSM were more likely than their uninfected peers to have traded sex within the previous year, to have had sex while high during their last sexual encounter, and to have UAI with a greater number of partners. Multivariate analyses indicated that for HIV-negative men, positive peer norms regarding safer sex and being Black or Latino predicted avoidance of UAI. Among HIV-positive men, having social support for safer sex and positive peer norms predicted avoidance of UAI. Young HIV-positive MSM are a relevant subgroup for prevention because they constitute a significant source from which future infections could be generated.

Position-specific HIV risk in a large network of homeless youths

OBJECTIVES

We examined interconnections among runaway and homeless youths (RHYs) and how aggregated network structure position was associated with HIV risk in this population.

METHODS

We collected individual and social network data from 136 RHYs. On the basis of these data, we generated a sociomatrix, accomplished network visualization with a "spring embedder," and examined k-cores. We used multivariate logistic regression models to assess associations between peripheral and nonperipheral network position and recent unprotected sexual intercourse.

RESULTS

Small numbers of nominations at the individual level aggregated into a large social network with a visible core, periphery, and small clusters. Female youths were more likely to be in the core, as were youths who had been homeless for 2 years or more. Youths at the periphery were less likely to report unprotected intercourse and had been homeless for a shorter duration.

CONCLUSIONS

HIV risk was a function of risk-taking youths' connections with one another and was associated with position in the overall network structure. Social network-based prevention programs, young women's housing and health programs, and housing-first programs for peripheral youths could be effective strategies for preventing HIV among this population.

Correlates of engaging in survival sex among homeless youth and young adults

Using a sample of 1,625 homeless youth and young adults aged 10 to 25 from 28 different states in the United States, this study examines the correlates of having engaged in survival sex. Findings suggest that differences exist based on demographic variables (gender, age, race, and sexual orientation), lifetime drug use (inhalants, Valium™, crack cocaine, alcohol, Coricidin™, and morphine), recent drug use (alcohol, ecstasy, heroin, and methamphetamine), mental health variables (suicide attempts, familial history of substance use, and having been in substance abuse treatment), and health variables (sharing needles and having been tested for HIV). In addition to replicating previous findings, this study's findings suggest that African American youth; gay, lesbian, or bisexual youth; and youth who had been tested for HIV were significantly more likely to have engaged in survival sex than White, heterosexual youth, and youth who had not been tested for HIV, respectively. Implications for interventions with youth and suggestions for future research are discussed.

Residential trajectory and HIV high-risk behaviors among Montréal street youth--a reciprocal relationship

Evidence has linked residential instability and engagement in high-risk behaviors. This paper longitudinally examines the relationship between changes in residential stability and changes in HIV risk behaviors among Montréal street youth (SY). Between April 2006 and May 2007, 419 SY (18-25 years old) were recruited in a cohort study. SY (using Montréal street youth agencies services) were eligible if they had had at least one 24-hour episode of homelessness in the previous 30 days. Baseline and follow-up interviews, carried out every 3 months, included completion of a questionnaire (based on Life History Calendar Technique) assessing daily sleeping arrangements since the last interview, and monthly sexual and drug use behaviors. Using mixed-effects logistic regression method, we examined the association between various risk behaviors and residential stability, reached when a youth resided in any of the following settings for a whole month: own place; friends'/partner's/parent's place; any types of housing service (excluding emergency shelters). Analyses were carried out controlling for gender, age, education level, lifetime duration of homelessness, childhood sexual trauma, and lifetime mental health disorders. As of January 2009, 360 SY (79% boys) had completed at least one follow-up interview, representing 4,889 months of follow-up. Residential stability was significantly associated with the following: sex exchange (adjusted odd ratio [AOR], 0.25; 95% confidence interval [CI], 0.14-0.37), drug injection (AOR, 0.55; CI, 0.33-0.76), daily alcohol consumption (AOR, 0.58; CI, 0.42-0.74), polydrug consumption (AOR, 0.61; CI, 0.50-0.73), polydrug consumption excluding marijuana (AOR, 0.55; CI, 0.45-0.65), and multiple sex partners (≥3 partners; AOR, 0.57; CI, 0.40-0.74). Our results suggest a reciprocal relationship between residential instability and HIV risk behaviors. This calls for more integrated services combining both individual and structural-level interventions to improve the health of street youth.

A comparison of drug use and risk behavior profiles among younger and older street youth

Among 559 street youth recruited between 2005 and 2007 in Vancouver, Canada, young drug users (<21 years of age) were compared with older drug users (≥21 years) with regard to recent drug use and sexual practices using multiple logistic regression. Older youth were more likely to be male and of Aboriginal ancestry, to have more significant depressive symptoms, to have recently engaged in crack smoking, and to have had a recent history of injection drug use. Young drug users, by contrast, were more likely to have engaged in recent binge alcohol use. Efforts to reduce drug use-related harm among street youth may be improved by considering the highly prevalent use of "harder" drugs and risk for depression among older youth.

Initiation to drug injection among street youth: a gender-based analysis

OBJECTIVE(S)

To estimate the incidence rate of initiation into drug injection and to identify predictors of initiation into drug injection separately among street girls and boys.

DESIGN

Data from two consecutive prospective street youth cohort studies (1995-2001 and 2001-2005) were used to conduct these analyses, stratified by gender.

METHODS

Data were collected using semi-annual interviewer-administered questionnaires. Variables from the following domains were considered in Cox regression models: socio-demographic characteristics, early and current substance abuse, marginalization, childhood traumatic sexual events and injection exposure.

RESULTS

Of the 946 youth who had never injected drugs at study entry, 86.4% completed at least two questionnaires representing 243 girls and 574 boys. Incidence rates of injection of 7.0 and 5.9 per 100 person-years were observed among these girls and boys respectively. Among girls, cocaine or crack use (adjusted hazard ratio (AHR)=1.97), heroin use (AHR=2.86), homelessness (AHR=2.49) and hanging out regularly with people who inject (AHR=4.46) all independently increased risk of first injection. Among boys, age decreased risk of initiating injection (AHR=0.90/year), while cocaine or crack use (AHR=2.14), heroin use (AHR=3.56), homelessness before age 16 (AHR=1.68), incest or rape before age 14 (AHR=1.98) and hanging out regularly with people who inject (AHR=1.66) all independently increased this risk.

CONCLUSIONS

Our findings suggest similar rates of initiation among girls and boys; however, factors associated with initiation vary by gender. This might lead to the design of more effective programs to prevent initiation into drug injection.

The effect of drug and sexual risk behaviours with social network and non-network members on homeless youths' sexually transmissible infections and HIV testing

BACKGROUND

The study examined whether engaging in drug and sexual risk behaviours with social network and non-network members (strangers) differentially affected the decision to test for sexually transmissible infections (STIs) and HIV.

METHODS

A cross-sectional survey was conducted among 249 homeless youths aged 14-21 years.

RESULTS

Multivariate analyses revealed that females were over three times more likely than males to test for STIs (adjusted odds ratio (AOR) = 3.34; 95% confidence interval (CI) = 1.54-7.25). For every one unit increase in age, there was a 37% increase in the likelihood of having tested for STIs (AOR = 1.37; 95% CI = 1.12-1.68). Youths who had sex after using alcohol and drugs with strangers were approximately 3.5 times more likely to have tested for STIs (AOR = 3.45; 95% CI = 1.38-8.61). For every one unit increase in age, there was a 26% increase in the likelihood of having tested for HIV (AOR = 1.26; 95% CI = 1.05-1.51). Youths who had sex with a stranger after using alcohol or drugs were over three times more likely to test for HIV (AOR = 3.22; 95% CI = 1.42-7.31). No social network variables reached significance for STI or HIV testing.

CONCLUSIONS

Being older and engaging in drug and sexual risk behaviours with strangers are important correlates of STI and HIV testing. Females are more likely than males to be tested for STIs. Engaging in risky behaviours with social network members was not a key factor in deciding whether to be tested.

Online social networking technologies, HIV knowledge, and sexual risk and testing behaviors among homeless youth

This study evaluates associations between online social networking and sexual health behaviors among homeless youth in Los Angeles. We analyzed survey data from 201 homeless youth accessing services at a Los Angeles agency. Multivariate (regression and logistic) models assessed whether use of (and topics discussed on) online social networking technologies affect HIV knowledge, sexual risk behaviors, and testing for sexually transmitted infections (STIs). One set of results suggests that using online social networks for partner seeking (compared to not using the networks for seeking partners) is associated with increased sexual risk behaviors. Supporting data suggest that (1) using online social networks to talk about safe sex is associated with an increased likelihood of having met a recent sex partner online, and (2) having online sex partners and talking to friends on online social networks about drugs and partying is associated with increased exchange sex. However, results also suggest that online social network usage is associated with increased knowledge and HIV/STI prevention among homeless youth: (1) using online social networks to talk about love and safe sex is associated with increased knowledge about HIV, (2) using the networks to talk about love is associated with decreased exchange sex, and (3) merely being a member of an online social network is associated with increased likelihood of having previously tested for STIs. Taken together, this study suggests that online social networking and the topics discussed on these networks can potentially increase and decrease sexual risk behaviors depending on how the networks are used. Developing sexual health services and interventions on online social networks could reduce sexual risk behaviors.

Multicity HIV seroprevalence in street youth, Ukraine

We conducted the first systematic, community-based, multicity assessment outside the USA of HIV seroprevalence, risk factors and linkage into clinical services among 929 street youth. After city-wide mapping, we used time-location sampling and randomly selected 74 venues in Odesa, Kyiv and Donetsk, Ukraine. Rapid HIV testing with post-test counselling was offered to all eligible youths aged 15-24 years. Overall, 18.4% (95% confidence interval 16.2-20.2) were HIV positive and 85% had previously unknown status. Rates were identical by sex. Subgroups with highest rates included orphans (26%), youths with histories of exchanging sex (35%), sexually transmitted infections (STIs) (37%), injection drug use (IDU) (42%) and needle sharing (49%). Independent predictors, similar across age groups and city, included being orphaned, time on the street, history of anal sex, STIs, exchanging sex, any drug use, IDU and needle sharing. Two-thirds (68%) of HIV-positive youths were linked to services. This high-risk population has many immediate needs.

The effect of early maltreatment, victimization, and partner violence on HIV risk behavior among homeless young adults

PURPOSE

The purpose of our study was to examine the relationship between child maltreatment, physical and sexual victimization, and partner violence victimization with human immunodeficiency virus (HIV) risk behaviors among a sample of homeless young adults from the midwestern United States.

METHODS

Data are from the Homeless Young Adult Project. A total of 199 young adults aged 19-26 years were interviewed over 14 months using a systematic sampling strategy. The final sample included 172 young adults who were homeless or had a history of running away and being homeless.

RESULTS

Results from the path analysis revealed that sexual abuse is directly linked with street sexual victimization which was positively associated with a greater number of HIV risk behaviors. Experiencing more types of physical abuse and neglect were positively correlated with partner violence victimization, which was, in turn, associated with more HIV risk behaviors. Those who suffered from more types of neglect also experienced more forms of sexual and physical victimization.

CONCLUSIONS

These findings have implications for service providers. Clinicians who serve homeless youth should recognize the potential effect that experiencing a variety of forms of victimization may have on health risk behaviors.

The positive role of social networks and social networking technology in the condom-using behaviors of homeless young people

OBJECTIVE

To examine the impact of condom-using peers in the social networks of homeless young people, differences in behaviors were assessed based on the social location of ties (home-based vs. street-based) and how those ties are maintained (face-to-face vs. via social networking technology).

METHODS

"Ego-centric" social network data were collected from 103 currently sexually active homeless young people aged 16-26 years in Los Angeles, California. Associations between condom use and the condom-using behaviors of social network influences were assessed using standard logistic regression.

RESULTS

About 52% of respondents had a street-based peer who was a condom user. Having such a peer was associated with a 70% reduction in the odds of having unprotected sex at last intercourse. About 22% of respondents had a condom-using, home-based peer with whom they communicated only via social networking technology. Having such a peer was associated with a 90% reduction in risky sexual behavior and a 3.5 times increase in safer sex behavior.

CONCLUSION

The study revealed several implications for new human immunodeficiency virus-prevention interventions that mobilize these networks and social networking technologies.

Survival sex work and increased HIV risk among sexual minority street-involved youth

OBJECTIVES

Exchanging sex for money, drugs, or other commodities for survival is associated with an array of HIV risks. We sought to determine if street-involved drug-using sexual minority youth are at greater risk for survival sex work and are more likely to engage in risk behaviors with clients.

METHODS

We examined factors associated with survival sex work among participants enrolled in the At Risk Youth Study using logistic regression. Self-reported risk behaviors with clients were also examined.

RESULTS

Of 558 participants eligible for this analysis, 75 (13.4%) identified as a sexual minority and 63 (11.3%) reported survival sex work in the past 6 months. Sexual minority males (adjusted odds ratio = 16.1, P < 0.001) and sexual minority females (adjusted odds ratio = 6.87, P < 0.001) were at significantly greater risk for survival sex work. Sexual minority youth were more likely to report inconsistent condom use with clients (odds ratio = 4.30, P= 0.049) and reported a greater number of clients in the past 6 months (median = 14 vs. 3, P = 0.008).

CONCLUSIONS

Sexual minority street youth are not only more likely to engage in survival sex work but also demonstrate elevated HIV risk behavior. These findings suggest that harm reduction and HIV prevention programs for sexual minority youth who exchange sex are urgently required.

Non-Injection Drug Use Patterns and History of Injection among Street Youth

AIMS

Efforts to prevent youth from initiating injection drug use require an understanding of the drug use patterns that predispose to injecting. Here we identify such patterns and describe the circumstances of first injection among street youth.

METHODS

From October 2005 to November 2007, data were collected for the At Risk Youth Study, a prospective cohort of 560 street-recruited youth aged 14-26 in Vancouver, Canada. Non-injection drug use behaviors were compared between those with and without a history of injection through multiple logistic regression. The circumstances of first injection were also examined in gender-stratified analyses.

RESULTS

Youth who had previously injected were more likely to have engaged in non-injection use of heroin or of crystal methamphetamine. Daily users of marijuana were less likely to have injected. Among prior injectors, the median age of first injection was lower among females. Females were also more likely to have had a sexual partner present at first injection and to have become a regular injector within one week of initiation.

CONCLUSION

Preventing transition to injection among street youth may require special attention to predisposing drug use patterns and should acknowledge gender differences in the circumstances of first injection.

The health impact of supportive housing for HIV-positive homeless patients: a randomized controlled trial

OBJECTIVES

We assessed the health impact of a housing and case management program, the Chicago Housing for Health Partnership, for homeless people with HIV.

METHODS

HIV-positive homeless inpatients at a public hospital (n = 105) were randomized to usual care or permanent housing with intensive case management. The primary outcome was survival with intact immunity, defined as CD4 count > or = 200 and viral load < 100,000. Secondary outcomes were viral loads, undetectable viral loads, and CD4 counts.

RESULTS

Outcomes were available for 94 of 105 enrollees (90%). Of 54 intervention participants, 35 (65%) reached permanent housing in program housing agencies. After 1 year, 55% of the intervention and 34% of the usual care groups were alive and had intact immunity (P = .04). Seventeen intervention (36%) and 9 usual care (19%) participants had undetectable viral loads (P = .051). Median viral loads were 0.89 log lower in the intervention group (P = .03). There were no statistical differences in CD4 counts.

CONCLUSIONS

Homelessness is a strong predictor of poor health outcomes and complicates the medical management of HIV. This housing intervention improved the health of HIV-positive homeless people.

Individual and environmental protective factors for risky sexual behavior among homeless youth: an exploration of gender differences

The goal of the current study was to identify potential individual and environmental protective factors for sex risk behavior among homeless youth. We explored gender differences in the prediction of unprotected sex and number of sex partners. Data were collected from 192 sexually active, homeless youth who were 14-21 years old. High rates of sex risk behavior were reported. Significant gender differences were found in STD rates with 19% of females and 2% of males reporting an STD diagnosis during the previous three months. Findings indicated that positive expectations for the future were associated with fewer sex partners for both genders, whereas decision making skills predicted a lower percentage of unprotected sex for males and fewer sex partners for females. For females, univariate analyses indicated that self-esteem and having a natural mentor may reduce the likelihood of unprotected sex, whereas multivariate analysis indicated that being employed or in school may play a protective role with respect to number of sex partners.

Homelessness and unstable housing associated with an increased risk of HIV and STI transmission among street-involved youth

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.

Transition to injection drug use among street youth--a qualitative analysis

OBJECTIVES

To examine social contexts and processes influencing transition to drug injection among street youth.

METHODS

42 street youth participated in in-depth interviews. A typology of experiences was built founded on youth's street life and drug use trajectories. The transition to drug injection was examined through these experiences.

RESULTS

We identified five types of mutually exclusive experiences. The "downtowner's" experience is characterised by early street life and drug consumption trajectories, and a strong identification with the downtown milieu. These youth progress from one drug to another and, in a milieu where drug injection is omnipresent, this escalation culminates in transition to injection. The "tripper" street life and substance use trajectories begin later and are less intense. Most "tripper" youth are already chronic hallucinogens users when they arrive in downtown Montréal. Although they judge "junkies" severely, they show some ambivalence towards injection. The "on the go" experience is characterised by trajectories of drug use and street life that are intermingled, leading to a loss of control. These youth, who often have serious delinquent behaviours, come to downtown Montréal to party and consume drugs, mostly stimulants. Their drug use pattern and network make them at high risk of starting cocaine injection. The "hard-luck's" experience is characterised by a lack of identification with the downtown milieu. These youth who use drugs recreationally, end up in the streets accidentally, often because of unemployment. The "alcoholic' experience is related to alcohol misuse. These youth usually end up in the streets due to this dependence. Their street involvement is mostly an experience of solitude. The risk of transitioning to injection for both these types is low.

CONCLUSIONS

Some combinations of street life and drug use trajectories seem to contribute to injection among street youth. Some important factors interact and increase the risk of street youth transitioning to injection: poor personal assets; early rupture with primary social institutions; social integration into subcultures where both street life and "drug trips" are fashionable, drug preferences and the local drug market.

HIV seroprevalence in street youth, St. Petersburg, Russia

BACKGROUND

Reliable data on HIV infection among Russian street youth are unavailable. The purpose of this study was to assess HIV seroprevalence among street youth in St Petersburg and to describe social, sexual, and behavioral characteristics associated with HIV infection.

METHODS

A cross-sectional assessment conducted during January-May 2006 included city-wide mapping of 41 street youth locations, random selection of 22 sites, rapid HIV testing for all consenting 15-19-year-old male and female street youth at these sites, and an interviewer-administered survey. Adjusted odds ratios (AOR) were calculated using logistic regression, accounting for intracluster homogeneity.

RESULTS

Of 313 participants, 117 (37.4%, 95% confidence interval 26.1-50.2%) were HIV infected. Subgroups with the highest seroprevalences included double orphans (64.3%), those with no place to live (68.1%), those previously diagnosed with a sexually transmitted infection (STI; 70.5%), those currently sharing needles (86.4%), and those currently using inhalants (60.5%) or injection drugs (78.6%), including Stadol (82.3%) or heroin (78.1%). Characteristics independently associated with HIV infection included injecting drugs (AOR 23.0), sharing needles (AOR 13.3), being a double or single orphan (AOR 3.3 and 1.8), having no place to live (AOR 2.4), and being diagnosed with a STI (AOR 2.1). Most HIV-infected street youth were sexually active (96.6%), had multiple partners (65.0%), and used condoms inconsistently (80.3%).

DISCUSSION

Street youth aged 15-19 years in St Petersburg, Russia, have an extraordinarily high HIV seroprevalence. In street youth who are injection drug users, HIV seroprevalence is the highest ever reported for eastern Europe and is among the highest in the world.

Housing stability over two years and HIV risk among newly homeless youth

The stability of living situation was examined as a predictor of young people's HIV-related sexual and drug use acts two years after leaving home for the first time. Newly homeless youth aged 12-20 years were recruited in Los Angeles County, California, U.S.A. (n = 261) and Melbourne, Australia (n = 165) and followed longitudinally at 3, 6, 12, 18, and 24 months. Their family history of moves and the type and frequency of moves over the two years following becoming newly homeless were examined. Regression analyses indicated that recent sexual risk two years after becoming newly homeless was not related to the instability of youths' living situations; condom use was higher among youth with more placements in institutional settings and among males. Drug use was significantly related to having moved more often over two years and Melbourne youth used drugs significantly more than youth in Los Angeles.

The impact of an integrated treatment on HIV risk behavior among homeless youth: a randomized controlled trial

While many studies provide useful information on the risk behaviors in which homeless youth engage, few prior studies evaluate Human Immunodeficiency Virus (HIV) risk related reduction strategies. In this study, homeless youth (n = 180) were recruited from a drop-in center and randomly assigned to one of two conditions, either an integrated individual cognitive-behavioral treatment and HIV prevention intervention that focused on skills building and education or to treatment as usual. All youth were assessed at entry into the program and at 3 and 6 month follow-up points. Findings showed an interaction between treatment condition, age and time. In the interaction, youth assigned to the integrated treatment reported greater condom usage than youth assigned to treatment as usual, with younger youth assigned to treatment as usual showing no change in condom use. The number of sexual partners reported by youth in both treatment conditions was also reduced over time. However, youth in both conditions continued to engage in other high-risk behaviors. The integrated treatment findings are promising and suggest that interventions which target both HIV risk behavior in addition to other life areas (substance use, mental health and housing) among homeless youth may be necessary in order to significantly impact high-risk behaviors among this unique group.

Pro-social and problematic social network influences on HIV/AIDS risk behaviours among newly homeless youth in Los Angeles

We examined the social network composition among newly homeless youth over time and assessed how pro-social and problematic peers affected sexual and drug-using HIV/AIDS risk-behaviours among 183 youth in Los Angeles County, California. The percentage of newly homeless youth who reported that 'most' or 'all' of their friends were attending school, had jobs, and got along with their families was 73%, 24%, and 50% respectively. Logistic regression models indicated that presence of these pro-social peers reduced HIV risk behaviours at two years; odds of HIV-risk were lower with a greater number of peers who attend school, have a job, or have positive family relationships or if networks change over time to include more of these peers. Presence of problematic peers increased the likelihood of HIV risk-taking; odds of HIV risk behaviours increased with a greater number of peers at baseline who steal, have overdosed, have been arrested, or are in a gang, or if networks change to include more of these peers. Interventions should target newly homeless youth in networks that contain problematic peers, but should strive to harness the naturally occurring pro-social peer influences present in these networks.

Pourquoi commencer ? L’initiation à l’injection de drogues selon les jeunes de la rue

Dans le cadre du développement d’une campagne de prévention du passage à l’injection de drogues chez les jeunes de la rue, nous avons mené sept groupes de discussion auprès de 37 d’entre eux âgés de 15 à 23 ans. L’analyse, à la fois déductive et inductive, a permis d’identifier les dimensions reflétant le point de vue des jeunes à propos de l’injection de drogues et des éléments qui favorisent le passage à l’injection dans leur milieu. Les résultats montrent que l’injection est généralement désapprouvée par les jeunes de la rue. Plusieurs ont des réserves, celles-ci étant liées aux conséquences négatives de l’injection. Ce que les jeunes redoutent le plus, c’est de devenir « accro », un risque qu’ils associent davantage à l’injection qu’aux autres modes de consommation. Malgré la désapprobation générale, au contact des utilisateurs de drogues par injection (UDI), il se produit une sorte de désensibilisation qui entraîne vers l’injection les plus vulnérables, soit les plus jeunes, surtout ceux qui satisfont leur besoin de sensations fortes à travers la drogue et recherchent une valorisation dans le monde de la rue. Divers éléments d’ordre individuel et social agissent alors pour amener ces jeunes à s’initier à l’injection. Plusieurs de ces éléments peuvent être modifiables par des interventions préventives.

Newly homeless youth STD testing patterns over time

PURPOSE

To use the Behavioral Model for Vulnerable Populations to examine the predisposing and need characteristics of newly homeless youth that are associated with sexually transmitted disease (STD) testing over time.

METHODS

A longitudinal cohort of newly homeless youth from Los Angeles County (n = 261; ages 12-20 years) were followed for 24 months. Youth were interviewed at baseline, 3, 6, 12, 18, and 24 months, and asked about their background, housing situation, emotional distress (using the Brief-Symptom Inventory), substance use, sexual risk behaviors, and their STD testing rates. We modeled our longitudinal data using logistic random effects models.

RESULTS

Characteristics of homeless youth that were associated with STD testing in our multivariate model included time in study (odds ratio [OR] 1.3, 95% confidence interval [CI] 1.1-1.6), age at baseline (OR 1.2, 95% CI 1.1-1.4), being African-American (OR 2.7, 95% CI 1.4-5.3), being from a mixed race/ethnic group (OR 2.8, 95% CI 1.3-5.8), self-identifying as a gay/bisexual male (OR 2.9, 95% CI 1.2-6.9), self-identifying as a heterosexual female (OR 2.2, 95% CI 1.3-3.7), using amphetamines (OR 1.7, 95% CI 1.1-2.6), and history of having gotten someone/becoming pregnant (OR 2.3, 95% CI 1.4-3.9). Youth who lived in an apartment were less likely to have received an STD test than youth who lived in other types of housing (OR .4, 95% CI .2-.9). Sexual risk behaviors such as inconsistent condom use (OR 1.0, 95% CI .6-1.4) and number of sexual partners over past 3 months (OR 1.1, 95% CI 1.0-1.1) were not predictive of STD testing over time.

CONCLUSIONS

A need exists for interventions to target young newly homeless youth who engage in high-risk sexual behaviors to increase their STD testing rates and thereby decrease their risk for HIV infection.

Sexual and drug use risk behaviors among children and youth in street circumstances in Porto Alegre, Brazil

We conducted a cross-sectional study to assess sexual and drug use risk in 161 children and youth in street circumstances in Porto Alegre, Brazil. Median age was 14 and 79% were male. Overall, 59% reported ever having had sex; a significantly higher proportion of males (66%) compared to females (30%). Overall, 39% reported illicit drug use in the last year, and only 1.2% reported injection drug use. In multivariate analyses, correlates of unsafe sex included younger age of sexual debut, and having a steady sex partner. Independent correlates of illicit drug use included lack of family contact, increased hours in the street daily, having had an HIV test, and older age. A high proportion of children and youth in street circumstances reported high risk sex and drug exposures, confirming their vulnerability to HIV/STD. Services Centers, such as where this research was carried out, offer an opportunity for interventions.

Evaluating methamphetamine use and risks of injection initiation among street youth: the ARYS study

Many Canadian cities are experiencing ongoing infectious disease and overdose epidemics among injection drug users (IDU). These health concerns have recently been exacerbated by the increasing availability and use of methamphetamine. The challenges of reducing health-related harms among IDU have led to an increased recognition that strategies to prevent initiation into injection drug use must receive renewed focus. In an effort to better explore the factors that may protect against or facilitate entry into injection drug use, the At Risk Youth Study (ARYS) has recently been initiated in Vancouver, Canada. The local setting is unique due to the significant infrastructure that has been put in place to reduce HIV transmission among active IDU. The ARYS study will seek to examine the impact of these programs, if any, on non-injection drug users. In addition, Vancouver has been the site of widespread use of methamphetamine in general and has seen a substantial increase in the use of crystal methamphetamine among street youth. Hence, the ARYS cohort is well positioned to examine the harms associated with methamphetamine use, including its potential role in facilitating initiation into injection drug use. This paper provides some background on the epidemiology of illicit drug use among street youth in North America and outlines the methodology of ARYS, a prospective cohort study of street youth in Vancouver, Canada.
