PurposeThe study aimed to determine the longitudinal associations between several variables assessing positive youth development and HIV risk-reduction practices.MethodsParticipants were 329 youth enrolled in out-of-school time programs in New York City. Longitudinal data were collected in three waves during 2008-2009 (baseline, 6-month follow-up, and 12-month follow-up). Because of the nested nature of the data, multivariate analyses were performed using multilevel models.ResultsAt baseline, HIV risk reduction was associated with female gender, greater individual-level program participation, and greater school connectedness. Over time, HIV risk reduction was associated with program-level participation: Individuals in groups with program-level participation scores 1 standard deviation below the average showed significant declines in risk reduction practices over the 1-year study period compared with individuals in more participatory programs.ConclusionsThis study provides support for the out-of-school environment as an important context for sustaining HIV risk reduction and positive health promotion practices. 相似文献

Runaway youth are 6–12 times more likely to become infected with HIV than other youth. Using a quasi-experimental design, the efficacy of an HIV prevention program was evaluated over 2 years among 2 groups of runaways: (1) those at 2 shelters who received Street Smart, an intensive HIV intervention program, and (2) youth at 2 control shelters. Street Smart provided youth with access to health care and condoms and delivered a 10-session skill-focused prevention program based on social learning theory to youth. Prior to analysis of the intervention's outcomes, propensity scores were used to identify comparable subgroups of youth in the intervention (n = 101) and control conditions (n = 86). Compared to females in the control condition, females in the intervention condition significantly reduced their unprotected sexual acts at 2 years and alcohol use, marijuana use, and the number of drugs used over 12 months. Male adolescents in the intervention condition showed significant reductions in marijuana use over 6 months compared to control youth. Adolescent HIV prevention programs must proactively identify mechanisms for maintaining behavior change over the long-term, and innovative research designs are needed to allow examination of agency-level interventions. 相似文献

Objectives
Testing for human immunodeficiency virus (HIV) is the key first step in HIV treatment and prevention. In 2006, the Centers for Disease Control and Prevention (CDC) recommended annual HIV testing for people at high risk for HIV infection. We evaluated HIV testing among men with high-risk heterosexual (HRH) contact and sexually active men who have sex with men (MSM) before and after the CDC recommendations.Methods
We used data from the National Survey of Family Growth, 2002 and 2006–2010, to assess proportions of HRH respondents and MSM reporting HIV testing in the prior 12 months, compare rates of testing before and after release of the 2006 CDC HIV testing guidelines, and examine demographic variables and receipt of health-care services as correlates of HIV testing.Results
Among MSM, the proportion tested was 37.2% (95% confidence interval [CI] 28.2, 47.2) in 2002, 38.2% (95% CI 25.9, 52.2) in 2006–2008, and 41.7% (95% CI 29.2, 55.3) in 2008–2010; among HRH respondents, the proportion was 23.7% (95% CI 20.5, 27.3) in 2002, 24.5% (95% CI 20.9, 28.7) in 2006–2008, and 23.9% (95% CI 20.2, 28.1) in 2008–2010. HIV testing was more likely among MSM and HRH respondents who received testing or treatment for sexually transmitted disease in the prior 12 months, received a physical examination in the prior 12 months (MSM only), or were incarcerated in the prior 12 months.Conclusions
The rate of annual HIV testing was low for men with sexual risk for HIV infection, and little improvement took place from 2002 to 2006–2010. Interventions aimed at men at risk, especially MSM, in both nonmedical and health-care settings, likely could increase HIV testing.New infections of human immunodeficiency virus (HIV) occur in the United States at a rate of approximately 50,000 per year, driven mostly by sexual transmission, particularly among men who have sex with men (MSM).1 In 2010, male-to-male sexual contact accounted for 63% of new HIV infections (78% among males), and heterosexual contact accounted for 25% of new HIV infections (11% among males).1,2 Although overall incidence has been relatively stable since 2006, among young MSM, particularly young black MSM, new infections continue to increase.1,3An estimated 14% of adults and adolescents living with HIV infection in the United States are undiagnosed, of whom 11% are males with high-risk heterosexual (HRH) contact and 62% are MSM.4 To increase the proportion of HIV-infected people who are aware of their status and link them to treatment and prevention services, the Centers for Disease Control and Prevention (CDC) recommended in 2006 that all people aged 13–64 years be tested at least once for HIV infection and that people at high risk for HIV infection, including men with HRH contact and sexually active MSM,5 be tested annually.Using data from multiple waves of a nationally representative survey, we examined the percentage of HRH and MSM respondents who reported having been tested for HIV in the prior 12 months. We compared rates of testing before and after the revised HIV testing guidelines5 were released by CDC in 2006. Additionally, because the 2006 CDC guidelines recommended that HIV screening be conducted as part of routine clinical care in all health-care settings,5 we examined HIV testing among men stratified by their reported use of health-care services in the prior 12 months and by several sociodemographic variables. 相似文献4.

Because there is little routine tuberculosis (TB) screening in Mexico, the prevalence of latent TB infection (LTBI) is unknown. In the context of an increasing HIV epidemic in Tijuana, Mexico, understanding prevalence of LTBI to anticipate emergence of increased LTBI reactivation is critical. Therefore, we recruited injection drug users, noninjection drug users, female sex workers, and homeless persons for a study involving risk assessment, rapid HIV testing, and TB screening. Of 503 participants, the overall prevalences of TB infection, HIV infection, and TB/HIV co-infection were 57%, 4.2%, and 2.2%, respectively; no significant differences by risk group (p>0.05) were observed. Two participants had TB (prevalence 398/100,000). Incarceration in Mexico (odds ratio [OR] 2.28), age (OR 1.03 per year), and years lived in Tijuana (OR 1.02 per year) were independently associated with TB infection (p<0.05). Frequent LTBI in marginalized persons may lead to increases in TB as HIV spreads. 相似文献

SUMMARY The purpose of this study was to explore the associations among living arrangements, HIV seroprevalence, and HIV risk and protective factors among 1,322 drug users participating in the University of Miami CARES (Community AIDS Research and Evaluation Studies) HIV intervention program. Living arrangements may be associated with HIV prevention behaviors; however, these influences can be either protective or destructive and therefore merit further examination. Statistical analyses indicated differences in the living arrangements of women compared with men, and significant associations were noted among women's living arrangements, HIV seroprevalence, risk behaviors and protective behaviors. The data from this study suggest that future HIV prevention research should investigate not only high-risk individuals, but persons with whom they interact often, especially those with whom they live or with whom they have sex. The next phase of HIV and drug interventions should be attentive to the incorporation of social context and social influences, paying particular attention to understudied populations such as high-risk women. 相似文献

This research used a structured storytelling narrative methodology to capture the lived experience of youth participants to
identify effective factors that helped them in three programs in Santa Barbara and Ventura Counties, California. Thirty-nine
youth aged 8–17 participated in two storytelling protocols at their home sites; one was a written narrative of a vivid experience
in the project, and the second was a group story about a character who had been a participant. Categorical content analysis
reported the following themes: positive peer experiences, caring adults, family atmosphere and learning new skills particularly
computer literacy. Participants reported changing from being isolated or acting out to succeeding in school. 相似文献

Black men who have sex with men (MSM) are at increased risk for HIV infection in the United States compared to other MSM.
The aim of this study was to investigate Black MSM’s sexual mixing patterns and partner characteristics in relation to sexual
risk taking, as a possible explanation for this observed increase in HIV incidence. Between January and July 2008, 197 Black
MSM were recruited via modified respondent-driven sampling and completed optional pretest and post-test HIV serological testing,
counseling, and a demographic, behavioral, and psychosocial assessment battery. Bivariate and multivariable logistic regression
procedures were used to examine predictors of risky sex across partner types. Overall, 18% of the sample was HIV-infected;
50% reported unprotected intercourse with men, 30% with women, and 5% with transgender partners. Fifty-three percent identified
as bisexual or straight, although all reported oral or anal sex with another man in the prior 12 months. Significant predictors
of engaging in at least one episode of: (1) serodiscordant unprotected anal sex (UAS) with a male partner in the past 12 months:
individuals at risk for social isolation (AOR = 4.23; p = 0.03), those with unstable housing (AOR = 4.19; p = 0.03), and those who used poppers at least weekly during sex (AOR = 5.90; p = 0.05); (2) UAS and/or unprotected vaginal intercourse with a female partner in the past 12 months: those with unstable
housing (AOR = 4.85; p = 0.04), those who used cocaine at least weekly during sex (AOR = 16.78; p = 0.006), being HIV-infected (AOR = 0.07; p = 0.02), and feeling social norms favor condom use (AOR = 0.60; p = 0.05); (3) UAS with the participants’ most recent nonmain male sex partner: use of alcohol and drugs during last sex by
participant (AOR = 4.04; p = 0.01), having sex with a Hispanic/Latino male (AOR = 2.71; p = 0.04) or a Black male (AOR = 0.50; p = 0.05) compared to a White male, and lower education (AOR = 1.31; p = 0.02). Findings suggest that sexual risk behaviors of Black MSM differ across partner type and by the characteristics of
their sexual networks and that this subpopulation of MSM are at high risk for HIV acquisition and transmission. Effective
prevention strategies need to address the distinct sexual and behavioral risk patterns presented by different sexual partnerships
reported by Black MSM. 相似文献

PurposeHIV self-testing allows youth to access testing outside of healthcare facilities. We investigated the feasibility of peer distribution of HIV self-testing (HIVST) kits to youth aged 16–24 years and examined the factors associated with testing off-site rather than at distribution points.MethodsFrom July 2019 to March 2020, HIVST kits were distributed on 12 tertiary education campuses throughout Zimbabwe. Participants chose to test at the HIVST distribution point or off-site. Factors associated with choosing to test off-site and factors associated with reporting a self-test result for those who tested off-site were investigated using logistic regression.ResultsIn total, 5,351 participants received an HIVST kit, over 129 days, of whom 3,319 (62%) tested off-site. The median age of recipients was 21 years (interquartile range 20–23); 64% were female. Overall, 2,933 (55%) returned results, 23 (1%) of which were reactive. Being female (adjusted odds ratio [aOR] 1.16, 95% confidence interval [CI] 1.03–1.31), living on campus (aOR 1.24, 95% CI 1.09–1.40), used a condom at last sex (aOR 1.44, 95% CI 1.26–1.65), and previous knowledge of HIVST (aOR 1.22, 95% CI 1.09–1.37) were associated with off-site testing. Attending a vocational college and teachers training college compared to a university was associated with choosing to return results for those who tested off-site (OR 2.40, 95% CI 1.65–3.48, p < .001).DiscussionHIVST distribution is an effective method of reaching a large number of youth over a short period of time. Efforts to increase awareness and roll out of HIVST on campuses should be coupled with support for linkage to HIV prevention and treatment services. 相似文献

Truancy is a serious concern in the United States. Its negative effects are so pervasive that in 2003 the Office of Juvenile
Justice and Delinquency Prevention named truancy prevention a national priority. Effective prevention of truancy requires
a thorough understanding of the characteristics that describe truant youth as well as factors that may put them at risk for
truancy. Unfortunately, surprisingly little is known about the correlates and/or causes of truancy. In this paper we explore
associations between truancy and several salient school-related risk and protective factors among a sample of youth who grew
up in socially disorganized neighborhoods of Denver, CO. We demonstrate that several school-related risk and protective factors
are associated with truancy. Perhaps most importantly, we identify that the two most robust predictors are school performance
and involvement with delinquent peers, and that these two variables form a synergistic relationship in which the relationship
between delinquent peer association and truancy is mitigated among students who perform well in school. Editors’ Strategic Implications: The authors use data from a large probability sample drawn from neighborhoods with high crime rates to identify key correlates
of truancy. They also draw attention to the dearth of efficacious truancy prevention efforts in spite of the magnitude of
the problem. 相似文献
