Abstract
In the U.S., HIV transmission rates have increased among male-male sexual contacts. Sex education reduces HIV-related risks; yet impacts for adolescent sexual minority males (ASMM) are less known. Data from a sample (n = 556) of ASMM (aged 13-18) in three U.S cities were used to examined associations between HIV education in school and sexual behaviors. Outcomes of interest included: sexually transmitted infection (STI), multiple sex partners, and condomless anal intercourse (CAI) with a male (all past 12 months). Adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) were calculated. Of 556 ASMM, 84% reported received HIV education. Among sexually active ASMM (n = 440) who received HIV education, fewer reported an STI (10% vs. 21%, aPR: 0.45, CI [0.26, 0.76]) and CAI (48% vs. 64%, aPR: 0.71, CI [0.58, 0.87]) than ASMM who did not receive HIV education. Protective effects of school HIV education on sexual behaviors are promising and suggest prevention education is vital to reducing HIV- and STI-related risks among ASMM.

Applying the Social Development Model in Middle Childhood to Promote Healthy Development: Effects From Primary School Through the 30s and Across Generations. JOURNAL OF DEVELOPMENTAL AND LIFE-COURSE CRIMINOLOGY 2021; 7:66-86. [PMID: 34150470 PMCID: PMC8210839 DOI: 10.1007/s40865-020-00152-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Revised: 07/27/2020] [Accepted: 08/24/2020] [Indexed: 06/13/2023]
Abstract
PURPOSE This paper describes the origins and application of a theory, the social development model (SDM), that seeks to explain causal processes that lead to the development of prosocial and problem behaviors. The SDM was used to guide the development of a multicomponent intervention in middle childhood called Raising Healthy Children (RHC) that seeks to promote prosocial development and prevent problem behaviors. This paper reviews and integrates the tests of the SDM and the impact of RHC. While the original results of both model and intervention tests have been published elsewhere, this paper provides a comprehensive review of these tests. As such this integrative paper provides one of the few examples of the power of theory-driven developmental preventive intervention to understand impact across generations and the power of embedding controlled tests of preventive intervention within longitudinal studies to understand causal mechanisms. METHODS Application of the SDM in the RHC intervention was tested in a quasi-experimental trial nested in the Seattle Social Development Project (SSDP). SSDP is a longitudinal study of 808 students who attended 18 public schools in Seattle, WA, and whose parents consented for their participation in longitudinal research when they were in Grade 5 (77% of the eligible population in participating schools). Students assented at each survey administration and consented to longitudinal follow-up when they turned 18. Panel subjects were followed and surveyed 15 times from Grade 5 through age 39, with most completion rates above 90%. RESULTS We describe effects of the full multicomponent RHC intervention delivered in Grades 1 through 6 by comparing outcomes of those children assigned to the full RHC intervention condition to controls from middle childhood through age 39. We also report the effects of the full RHC intervention on the firstborn children of participants compared with the firstborn children of controls. CONCLUSIONS We discuss use of the theory to guide development and testing of preventive interventions and the utility of nesting intervention tests within longitudinal studies for testing both theory and interventions.

Abstract
Elementary schools can be effective sites for universal preventive interventions. Less is known about how long effects of intervention in elementary grades last. Can they improve outcomes in adulthood? To test effects of a social developmental intervention in the elementary grades on adult life through the 30s, the Seattle Social Development Project, a nonrandomized controlled trial, followed all consenting 5th-grade students (N = 808) from 18 Seattle public elementary schools from age 10 (in 1985) to age 39 (in 2014), with 88% retention. The sample was gender balanced and ethnically and economically diverse. The full intervention, called Raising Healthy Children, continued from Grades 1 through 6 and consisted of teacher in-service training in classroom management and instructional methods; cognitive, social, and refusal skills training for children; and parent workshops in child behavior monitoring and management, academic support, and anticipatory guidance. Using structural equation modeling, we examined intervention effects from age 30 to age 39 across 9 constructs indicating 3 domains of adult life: health behavior, positive functioning, and adult health and success. An omnibus test across all 9 constructs indicated a significant positive overall intervention-control difference. Examined individually, significant intervention effects included better health maintenance behavior, mental health, and overall adult health and success. Significant effects were not found on substance use disorder symptoms, sex-risk behaviors, or healthy close relationships in the 30s. Results indicate that sustained, theory-based, multicomponent intervention in the elementary grades can produce lasting changes in health maintenance, mental health, and adult functioning through the 30s.

Integrating Individual and Contextual Factors to Explain Disparities in HIV/STI Among Heterosexual African American Youth: A Contemporary Literature Review and Social Ecological Model. ARCHIVES OF SEXUAL BEHAVIOR 2020; 49:1939-1964. [PMID: 32157486 PMCID: PMC7321914 DOI: 10.1007/s10508-019-01609-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/08/2018] [Revised: 12/03/2019] [Accepted: 12/10/2019] [Indexed: 05/21/2023]
Abstract
Heterosexual African American youth face substantial disparities in sexual health consequences such as HIV and STI. Based on the social ecological framework, the current paper provides a comprehensive, narrative review of the past 14 years of literature examining HIV/STI risk, including risky sexual behavior, among heterosexual African American youth and a conceptual model of risk among this population. The review found that individual psychological and biological factors are insufficient to explain the sexual health disparities faced by this group; instead, structural disadvantage, interpersonal risk, and community dysfunction contribute to the disparity in HIV/STI outcomes directly and indirectly through individual psychological factors. The conceptual model presented suggests that for African American youth, (1) HIV/STI risk commonly begins at the structural level and trickles down to the community, social, and individual levels, (2) risk works in a positive feedback system such that downstream effects compound the influence of structural risks, and (3) contextual and individual risk factors must be considered within the advanced stage of the epidemic facing this population. Despite advanced HIV and STI epidemics among heterosexual African American youth, multisystemic interventions that target structural risk factors and their downstream effects are posited to reduce the disparity among this high-risk population.

Abstract
IMPORTANCE Trials of preventive interventions for children that were implemented in the 1980s have reported sustained positive outcomes on behavioral and health outcomes into adulthood, years after the end of the intervention. This present study examines whether intervention in childhood may show sustained benefits across generations. OBJECTIVE To examine possible intervention outcomes on the offspring of individuals (now parents) who participated in the Raising Healthy Children preventive intervention as children in the elementary grades. DESIGN, SETTING, AND PARTICIPANTS This nonrandomized controlled trial was conducted in public elementary schools serving high-crime areas in Seattle, Washington. The panel originated in Seattle but was followed up locally and in out-of-state locations over time. Data analyzed in this study were collected from September 1980 to June 2011, with follow-up of the firstborn offspring (aged 1 through 22 years) of 182 parents who had been in the full intervention vs control conditions in childhood. Their children were assessed across 7 waves in 2 blocks (2002-2006 and 2009-2011). Data were analyzed for this article from September 2018 through January 2019. INTERVENTIONS In grades 1 through 6, the Raising Healthy Children intervention provided elementary school teachers with methods of classroom management and instruction, first-generation (G1) parents with skills to promote opportunities for children's active involvement in the classroom and family, and second-generation (G2) child with social and emotional skills training. MAIN OUTCOMES AND MEASURES Outcomes examined in the third-generation (G3) offspring were self-regulation (emotion, attention, and behavioral regulation), cognitive capabilities, and social capabilities. Risk behaviors, including substance use and delinquency, were examined from age 6 years to study completion. Early onset of sexual activity was examined from age 13 years to study completion. Intent-to-treat analyses controlled for potential confounding factors. RESULTS A total of 182 G3 children were included in this analysis (72 in the full intervention and 110 in the control condition; mean age at first wave of data collection, 7 [range, 1-13] years). Significant differences in the offspring of intervention parents were observed across 4 domains: improved early child developmental functioning (ages 1-5 years; significant standardized β range, 0.45-0.56), lower teacher-rated behavioral problems (ages 6-18 years; significant standardized β range, -0.39 to -0.46), higher teacher-rated academic skills and performance (ages 6-18 years; significant standardized β range, 0.34-0.49), and lower child-reported risk behavior (ages 6-18 years; odds ratio for any drug use [alcohol, cigarettes, or marijuana], 0.27 [95% CI, 0.10-0.73]). CONCLUSIONS AND RELEVANCE To our knowledge, this is the first study to report significant intervention differences in the offspring of participants in a universal childhood preventive intervention. Cost-benefit analyses have examined the benefits of childhood intervention in the target generation. The present study suggests that additional benefits can be realized in the next generation as well. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT04075019.

Abstract
Assessments of youth risk and protective factors (RPFs) for substance use, delinquency, and violence have been used by communities to identify priorities and target them with prevention interventions. These same RPFs may also predict other youth problems. This study examined the strength and consistency of relationships of 41 ecological RPFs that predict antisocial behavior and substance use with sexual behavior outcomes in a sample of 2150 urban youth in 10th and 12th grade. After adjusting for controls, findings identify significant associations among the majority of community, school, family, peer, and individual risk factors, and family, peer, and individual protective factors, with sexual behavior outcomes, specifying unique associations among multiple factors with risky sex relative to both safe sex and not being sexually active. Prevention programming that targets common predictors for multiple problems may address a broad array of outcomes, including sexual health risk behaviors.

Abstract
This 15-year longitudinal follow-up of a randomized controlled trial of a parenting-focused preventive intervention for divorced families examined cascade models of program effects on offsprings' competence. It was hypothesized that intervention-induced improvements in parenting would lead to better academic, work, peer, and romantic competence in emerging adulthood through effects on behavior problems and competencies during adolescence. Families (N = 240) participated in the 11-session program or literature control condition when children were ages 9-12. Data were drawn from assessments at pretest, posttest, and follow-ups at 3 and 6 months and 6 and 15 years. Results showed that initial intervention effects of parenting on externalizing problems in adolescence cascaded to work outcomes in adulthood. Parenting effects also directly impacted work success. For work outcomes and peer competence, intervention effects were moderated by initial risk level; the program had greater effects on youths with higher risk at program entry. In addition, intervention effects on parenting led to fewer externalizing problems that in turn cascaded to better academic outcomes, which showed continuity into emerging adulthood. Results highlight the potential for intervention effects of the New Beginnings Program to cascade over time to affect adult competence in multiple domains, particularly for high-risk youths.

Abstract
BACKGROUND Because little is known about long-term effects of adolescent protective factors across multiple health domains, we examined associations between adolescent connectedness and multiple health-related outcomes in adulthood. METHODS We used weighted data from Waves I and IV of the National Longitudinal Study of Adolescent to Adult Health (n = 14 800). Linear and logistic models were used to examine associations between family and school connectedness in adolescence and self-reported health risk behaviors and experiences in adulthood, including emotional distress, suicidal thoughts and attempts, physical violence victimization and perpetration, intimate partner physical and sexual violence victimization, multiple sex partners, condom use, sexually transmitted infection (STI) diagnosis, prescription drug misuse, and other illicit drug use. RESULTS In multivariable analyses, school connectedness in adolescence had independent protective associations in adulthood, reducing emotional distress and odds of suicidal ideation, physical violence victimization and perpetration, multiple sex partners, STI diagnosis, prescription drug misuse, and other illicit drug use. Similarly, family connectedness had protective effects for emotional distress, all violence indicators, including intimate partner violence, multiple sex partners, STI diagnosis, and both substance use indicators. Compared to individuals with low scores for each type of connectedness, having high levels of both school and family connectedness was associated with 48% to 66% lower odds of health risk behaviors and experiences in adulthood, depending on the outcome. CONCLUSIONS Family and school connectedness may have long-lasting protective effects across multiple health outcomes related to mental health, violence, sexual behavior, and substance use. Increasing both family and school connectedness during adolescence has the potential to promote overall health in adulthood.

Abstract
We systematically reviewed the literature to assess the effectiveness of school-based programs to prevent HIV and other sexually transmitted infections (STI) among adolescents in the USA. We searched six databases including PubMed for studies published through May 2017. Eligible studies included youth ages 10-19 years and assessed any school-based programs in the USA that reported changes in HIV/STI incidence or testing. We used Cochrane tool to assess the risk of bias and GRADE to determine the evidence quality for each outcome. Three RCTs and six non-RCTs, describing seven interventions, met study inclusion criteria. No study reported changes in HIV incidence or prevalence. One comprehensive intervention, assessed in a non-RCT and delivered to pre-teens, reduced STI incidence into adulthood (RR 0.36, 95% CI 0.23-0.56). A non-RCT examining chlamydia and gonorrhea incidence before and after a condom availability program found a significant effect at the city level among young men 3 years later (RR 0.43, 95% CI 0.23-0.80). The remaining four interventions found no effect. The effect on STI prevalence was also not significant (pooled RR 0.83 from two non-RCTs, RR 0.70 from one RCT). Only one non-RCT showed an increase in HIV testing (RR 3.19, 95% CI 1.24-8.24). The quality of evidence for all outcomes was very low. Studies, including the RCTs, were of low methodological quality and had mixed findings, thus offering no persuasive evidence for the effectiveness of school-based programs. The most effective intervention spanned 6 years, was a social development-based intervention with multiple components, rather than a sex education program, and started in first grade.

Effects of Interventions Addressing School Environments or Educational Assets on Adolescent Sexual Health: Systematic Review and Meta-analysis. PERSPECTIVES ON SEXUAL AND REPRODUCTIVE HEALTH 2019; 51:91-107.

Abstract
CONTEXT School-based interventions that aim to modify sexual health knowledge, attitudes and behaviors have mixed and often unsustained effects on adolescent sexual health outcomes. However, observational evidence suggests that broader school-related factors, such as school climate and academic attainment, can influence outcomes. METHODS Nine databases were searched in July 2017 for randomized and quasi-experimental evaluations of interventions addressing school-level environment or student-level educational assets, to examine whether such interventions can promote young people's sexual health. Searches were limited to studies published since 1990 but were not restricted by language. Studies were assessed for risk of bias and synthesized narratively and meta-analytically. RESULTS Searches yielded 11 evaluations, published from 1999 to 2016, of interventions related to school-level environment or student-level educational assets. Because of inconsistent reporting, the risk of bias was not clear for most studies, and meta-analysis was possible for only one outcome. The meta-analysis of three randomized trials provided some evidence that school-environment interventions may delay sexual debut (pooled odds ratio, 0.5). Narrative synthesis of the remaining outcomes found mixed results, but suggests that interventions addressing school-level environment may delay sexual debut and that those addressing student-level educational assets may reduce risk of pregnancy and STDs. CONCLUSIONS Additional and more rigorous evidence is needed to assess the probability that interventions addressing school-related factors are effective and to provide better understanding of the mechanisms by which they may work to improve adolescent sexual health.

Abstract
The utility of evaluating mediation effects spans across research domains. The model facilitates investigation of underlying mechanisms of event timing and, as such, has the potential to help strengthen etiological research and inform intervention work that incorporates the evaluation of mediating variables. In order for the analyses to be maximally useful however, it is critical to employ methodology appropriate for the data under investigation. The purpose of this paper is to evaluate a regression-based approach to estimating mediation effects with discrete-time survival outcomes. We empirically evaluate the performance of the discrete-time survival mediation model in a statistical simulation study, and demonstrate that results are functionally equivalent to estimates garnered from a potential-outcomes framework. Simulation results indicate that parameter estimates of mediation in the model were statistically accurate and precise across the range of examined conditions. Type 1 error rates were also tolerable in the conditions studied. Adequate power to detect effects in the model, with binary X and continuous M variables, required effect sizes of the mediation paths to be medium or large. Possible extensions of the model are also considered.

Abstract
OBJECTIVE Effects are reported of the Family Bereavement Program (FBP) on the mental health of bereaved youth and their surviving parent 15 years following the program. METHOD On-hundred and 56 families (244 children ages 8-16; 54% male; 67% Non-Hispanic White) were randomly assigned to receive either the FBP (N = 90) or a literature control condition (N = 66). At the 15-year follow-up 80% of the youth and 76% of the bereaved parents were reinterviewed. Mental health problems and service use were self-reported by young adults and their parents. Key informants reported on mental health problems of young adults. RESULTS Young adults in the FBP reported significantly less use of mental health services and of psychiatric medication than controls. Key informants reported significantly lower mental health problems for young adults who were in FBP as compared with controls and for those who were younger lower internalizing and externalizing problems for those in the FBP as compared with controls. Bereaved parents reported a significantly lower rate of alcoholism and less use of support groups than controls. CONCLUSIONS The results provided evidence that FBP led to lower mental health problems and less service use by bereaved young adults and their parents as compared with controls.

Abstract
This meta-analysis reviewed 82 school-based, universal social and emotional learning (SEL) interventions involving 97,406 kindergarten to high school students (Mage = 11.09 years; mean percent low socioeconomic status = 41.1; mean percent students of color = 45.9). Thirty-eight interventions took place outside the United States. Follow-up outcomes (collected 6 months to 18 years postintervention) demonstrate SEL's enhancement of positive youth development. Participants fared significantly better than controls in social-emotional skills, attitudes, and indicators of well-being. Benefits were similar regardless of students' race, socioeconomic background, or school location. Postintervention social-emotional skill development was the strongest predictor of well-being at follow-up. Infrequently assessed but notable outcomes (e.g., graduation and safe sexual behaviors) illustrate SEL's improvement of critical aspects of students' developmental trajectories.

Abstract
The emerging field of behavioral epigenetics is producing a growing body of evidence that early life experience and social exposure can alter the way by which genes are marked with DNA methylation. We hypothesize that changes in DNA methylation as well as other epigenetic markers could generate stable phenotypes. Early life adversity appears to result in altered DNA methylation of genes in the brain and peripheral tissues, and these changes are associated with adverse phenotypic changes. Although the data are still sparse, early epigenetic studies have provided a proof of principle that experiences and the environment leave marks on genes, and thus suggest molecular and physical mechanisms for the epidemiological concept of gene-environment interaction. The main attraction of DNA methylation for type I (TI) translational prevention science is the fact that, different from genetic changes that are inherited from our ancestors, DNA methylation is potentially preventable and reversible and, therefore, there is a prospect of epigenetically targeted interventions. In addition, DNA methylation markers might provide an objective tool for assessing effects of early adverse experience on individual risks as well as providing objective measures of progress of an intervention. In spite of this great potential promise of the emerging field of social and translational epigenetics, many practical challenges remain that must be addressed before behavioral epigenetics could become translational epigenetics.

Abstract
INTRODUCTION Sexual risk behaviors (SRBs) often lead to sexually transmitted infections (STI), yet little is known about what drives SRB and whether this differs by sex. METHOD Participants (n = 920; 75% white) were drawn from the Raising Healthy Children study, enrolled in 1993 and 1994 in grades 1 to 2, and followed up through age 24/25 years. Lifetime STI diagnosis was defined by self-report or seropositivity for Chlamydia trachomatis or herpes simplex virus 2. Multivariable models assessed individual (social skills, behavioral disinhibition) and environmental factors (family involvement, school bonding, antisocial friends) predictive of STI diagnosis as mediated by 3 proximal SRB (sex under the influence of drugs or alcohol, condom use, lifetime number of sex partners). RESULTS Twenty-five percent of participants had ever had an STI. All SRBs differed by sex (P < 0.001), and female participants were more likely to have had an STI (P < 0.001). Behavioral disinhibition and antisocial friends in adolescence were associated with more SRB for both sexes, whereas social skills were associated with less SRB in female but more in male participants. Considering SRB and individual and environmental factors together, lifetime number of sex partners (adjusted relative risk [ARR], 1.04per partner; 95% confidence interval [CI], 1.03-1.05) and inconsistent condom use (ARR, 1.10per year; 95% CI, 1.04-1.16) were associated with increased risk of STI, whereas social skills were associated with decreased risk of STI (ARR, 0.84; 95% CI, 0.75-0.93). Behavioral disinhibition seemed to drive SRB, but family involvement mitigated this in several cases. CONCLUSIONS Adolescent environmental influences and individual characteristics drive some SRB and may be more effective targets for STI/HIV prevention interventions than proximal risk behaviors.

Abstract
BACKGROUND School-based sexual and reproductive health programmes are widely accepted as an approach to reducing high-risk sexual behaviour among adolescents. Many studies and systematic reviews have concentrated on measuring effects on knowledge or self-reported behaviour rather than biological outcomes, such as pregnancy or prevalence of sexually transmitted infections (STIs). OBJECTIVES To evaluate the effects of school-based sexual and reproductive health programmes on sexually transmitted infections (such as HIV, herpes simplex virus, and syphilis), and pregnancy among adolescents. SEARCH METHODS We searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) for published peer-reviewed journal articles; and ClinicalTrials.gov and the World Health Organization's (WHO) International Clinical Trials Registry Platform for prospective trials; AIDS Educaton and Global Information System (AEGIS) and National Library of Medicine (NLM) gateway for conference presentations; and the Centers for Disease Control and Prevention (CDC), UNAIDS, the WHO and the National Health Service (NHS) centre for Reviews and Dissemination (CRD) websites from 1990 to 7 April 2016. We handsearched the reference lists of all relevant papers. SELECTION CRITERIA We included randomized controlled trials (RCTs), both individually randomized and cluster-randomized, that evaluated school-based programmes aimed at improving the sexual and reproductive health of adolescents. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion, evaluated risk of bias, and extracted data. When appropriate, we obtained summary measures of treatment effect through a random-effects meta-analysis and we reported them using risk ratios (RR) with 95% confidence intervals (CIs). We assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS We included eight cluster-RCTs that enrolled 55,157 participants. Five trials were conducted in sub-Saharan Africa (Malawi, South Africa, Tanzania, Zimbabwe, and Kenya), one in Latin America (Chile), and two in Europe (England and Scotland). Sexual and reproductive health educational programmesSix trials evaluated school-based educational interventions.In these trials, the educational programmes evaluated had no demonstrable effect on the prevalence of HIV (RR 1.03, 95% CI 0.80 to 1.32, three trials; 14,163 participants; low certainty evidence), or other STIs (herpes simplex virus prevalence: RR 1.04, 95% CI 0.94 to 1.15; three trials, 17,445 participants; moderate certainty evidence; syphilis prevalence: RR 0.81, 95% CI 0.47 to 1.39; one trial, 6977 participants; low certainty evidence). There was also no apparent effect on the number of young women who were pregnant at the end of the trial (RR 0.99, 95% CI 0.84 to 1.16; three trials, 8280 participants; moderate certainty evidence). Material or monetary incentive-based programmes to promote school attendanceTwo trials evaluated incentive-based programmes to promote school attendance.In these two trials, the incentives used had no demonstrable effect on HIV prevalence (RR 1.23, 95% CI 0.51 to 2.96; two trials, 3805 participants; low certainty evidence). Compared to controls, the prevalence of herpes simplex virus infection was lower in young women receiving a monthly cash incentive to stay in school (RR 0.30, 95% CI 0.11 to 0.85), but not in young people given free school uniforms (Data not pooled, two trials, 7229 participants; very low certainty evidence). One trial evaluated the effects on syphilis and the prevalence was too low to detect or exclude effects confidently (RR 0.41, 95% CI 0.05 to 3.27; one trial, 1291 participants; very low certainty evidence). However, the number of young women who were pregnant at the end of the trial was lower among those who received incentives (RR 0.76, 95% CI 0.58 to 0.99; two trials, 4200 participants; low certainty evidence). Combined educational and incentive-based programmesThe single trial that evaluated free school uniforms also included a trial arm in which participants received both uniforms and a programme of sexual and reproductive education. In this trial arm herpes simplex virus infection was reduced (RR 0.82, 95% CI 0.68 to 0.99; one trial, 5899 participants; low certainty evidence), predominantly in young women, but no effect was detected for HIV or pregnancy (low certainty evidence). AUTHORS' CONCLUSIONS There is a continued need to provide health services to adolescents that include contraceptive choices and condoms and that involve them in the design of services. Schools may be a good place in which to provide these services. There is little evidence that educational curriculum-based programmes alone are effective in improving sexual and reproductive health outcomes for adolescents. Incentive-based interventions that focus on keeping young people in secondary school may reduce adolescent pregnancy but further trials are needed to confirm this.

Abstract
Preventive interventions are often designed and tested with the immediate program period in mind, and little thought that the intervention sample might be followed up for years or even decades beyond the initial trial. However, depending on the type of intervention and the nature of the outcomes, long-term follow-up may well be appropriate. The advantages of long-term follow-up of preventive interventions are discussed and include the capacity to examine program effects across multiple later life outcomes, the ability to examine the etiological processes involved in the development of the outcomes of interest, and the ability to provide more concrete estimates of the relative benefits and costs of an intervention. In addition, researchers have identified potential methodological risks of long-term follow-up such as inflation of type 1 error through post hoc selection of outcomes, selection bias, and problems stemming from attrition over time. The present paper presents a set of seven recommendations for the design or evaluation of studies for potential long-term follow-up organized under four areas: Intervention Logic Model, Developmental Theory and Measurement Issues; Design for Retention; Dealing with Missing Data; and Unique Considerations for Intervention Studies. These recommendations include conceptual considerations in the design of a study, pragmatic concerns in the design and implementation of the data collection for long-term follow-up, as well as criteria to be considered for the evaluation of an existing intervention for potential for long-term follow-up. Concrete examples from existing intervention studies that have been followed up over the long term are provided.

Sexually transmitted infection screening and reproductive health counseling in adolescent renal transplant recipients: Perceptions and practice patterns. A study from the Midwest Pediatric Nephrology Consortium. Pediatr Transplant 2015; 19:704-8.

Abstract
We wanted to identify practice patterns and perceived barriers among pediatric nephrologists regarding STI screening and reproductive health counseling in adolescent renal transplant recipients. We created an online Likert-scaled survey. Response rate was 54%. The majority (83%) believed STI risk in their patients was similar to or higher than healthy teens. Interestingly, while 67% felt moderately or very confident in asking about sexual activity and counseling about safer sex, only 43% routinely or always inquired about sexual activity, and only 42% routinely or always counseled about safer sex. Fifty-four percent routinely or always discussed contraceptive options and implications of unintentional pregnancy. Fifty-one percent routinely or always referred patients to a gynecologist or adolescent provider for contraception prescription. The most common counseling mechanism was informal discussions in clinic (87%). Ten percent had no mechanism in place. Major barriers included time limitations, adolescents' fear regarding confidentiality, and lack of professional training. This is the first report of perceptions and practice patterns of pediatric nephrologists regarding STI screening and reproductive health counseling. Providers seem to recognize the importance of counseling; however, translation into practice remains low. Professional training in this area and increased encounter time could improve counseling delivery and thereby reduce risk in this population.

Efficacy of a Brief Intervention to Reduce Substance Use and Human Immunodeficiency Virus Infection Risk Among Latino Youth. J Adolesc Health 2015; 57:S1054-139X(15)00285-2. [PMID: 26549551 PMCID: PMC4799768 DOI: 10.1016/j.jadohealth.2015.07.006] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2015] [Revised: 07/17/2015] [Accepted: 07/17/2015] [Indexed: 11/16/2022]
Abstract
PURPOSE Familias Unidas is an efficacious and effective family-based intervention for preventing and reducing substance use and unsafe sexual behaviors among Latino youth. To facilitate its dissemination, Familias Unidas was shortened from a 12-week intervention to a 6-week intervention and evaluated. We hypothesized that brief Familias Unidas would be efficacious in reducing substance use and unsafe sexual behaviors relative to a comparison condition. METHODS We randomized 160 ninth-grade Latino adolescents and their families to brief Familias Unidas or a community practice control condition. Adolescents were surveyed at baseline and 6, 12, and 24 months after baseline. RESULTS At 24 months, youth randomized to brief Familias Unidas had a significantly lower sexual initiation rate (34.0%) relative to control (55.0%), p = .02. Brief Familias Unidas also increased positive parenting. Moderation analyses revealed that brief Familias Unidas was significantly associated with decreased substance use initiation among girls (30.4% vs. 64.0%, respectively; p = .02), but not boys (28.0% vs. 26.7%, respectively; p = .91). Brief Familias Unidas was also significantly associated with reduced unsafe sex among adolescents aged 15 years or less (p < .001), but not among older adolescents (p = .37). Moderating effects were also found for family-level variables. CONCLUSIONS Brief Familias Unidas was efficacious in reducing sex initiation and improving positive parenting. Moderation analyses suggested that brief Familias Unidas was efficacious in reducing substance use initiation and unsafe sex for certain Hispanic adolescent subgroups, highlighting the importance of conducting moderation analyses, and of targeting interventions for specific subgroups.

Abstract
AIM To understand the influential factors related to sexual behaviors among Asian-American adolescents and to evaluate common factors across successful sexual education programs for this population. BACKGROUND Despite a rapid increase in cases of STIs/HIV among Asian-American populations, there remains a need for a comprehensive understanding of the influential factors related to risky sexual behaviors for this population. METHODS An integrative literature review was conducted. Peer-reviewed articles and government resources were analyzed. RESULTS Five influential factors were identified: family-centered cultural values, parental relationship, acculturation, gender roles, and lack of knowledge and information about sex and STIs. Only two sexual educational programs met the inclusion criteria and provided evidence towards effectiveness: Safer Choices and Seattle Social Development Project. CONCLUSIONS The findings of this study indicate an urgent need for culturally sensitive sexual education programs that incorporate the identified influential factors, especially cultural values in order to reduce risky sexual behaviors among Asian-American adolescents.

Understanding the link between early sexual initiation and later sexually transmitted infection: test and replication in two longitudinal studies. J Adolesc Health 2014; 54:435-441.e2.

Abstract
PURPOSE Age at sexual initiation is strongly associated with sexually transmitted infections (STI); yet, prevention programs aiming to delay sexual initiation have shown mixed results in reducing STI. This study tested three explanatory mechanisms for the relationship between early sexual debut and STI: number of sexual partners, individual characteristics, and environmental antecedents. METHODS A test-and-replicate strategy was employed using two longitudinal studies: the Seattle Social Development Project (SSDP) and Raising Healthy Children (RHC). Childhood measures included pubertal age, behavioral disinhibition, and family, school, and peer influences. Alcohol use and age of sexual debut were measured during adolescence. Lifetime number of sexual partners and having sex under the influence were measured during young adulthood. Sexually transmitted infection diagnosis was self-reported at age 24. Early sex was defined as debut at <15 years. Path models were developed in SSDP evaluating relationships between measures, and were then tested in RHC. RESULTS The relationship between early sex and STI was fully mediated by lifetime sex partners in SSDP, but only partially in RHC, after accounting for co-occurring factors. Behavioral disinhibition predicted early sex, early alcohol use, number of sexual partners, and sex under the influence, but had no direct effect on STI. Family management protected against early sex and early alcohol use, whereas antisocial peers exacerbated the risk. CONCLUSIONS Early sexual initiation, a key mediator of STI, is driven by antecedents that influence multiple risk behaviors. Targeting co-occurring individual and environmental factors may be more effective than discouraging early sexual debut and may concomitantly improve other risk behaviors.
