Mapping the Complexity of Suicide by Combining Participatory Modeling and Network Science
Giabbanelli PJ , Galgoczy MC , Nguyen DM , Foy R , Rice KL , Nataraj N , Brown MM , Harper CR . Proc IEEE ACM Int Conf Adv Soc Netw Anal Min 12/28/2021 12 (1) 339-342 Suicide rates are steadily increasing among youth in the USA. Although several theories and frameworks of suicide have been developed, they do not account for some of the features that define suicide as a complex problem, such as a large number of interrelationships and cycles. In this paper, we create the first c omprehensive m ap o f a dverse c hildhood experiences (ACEs) and suicide for youth, by combining a participatory approach (involving 15 subject-matter experts) and network science. This results in a map of 946 edges and 361 concepts, in which we identify ACEs to be the most important factor (per degree centrality). The map is openly shared with the community to support further network analyses (e.g., decomposition into clusters). Similarly to the high-impact Foresight Map developed in the context of obesity, the largest map on suicide and ACEs to date presented in this paper can start a discussion at the crossroad of suicide research and network science, thus bringing new means to address a complex public health challenge. |
Witnessing community violence, gun carrying, and associations with substance use and suicide risk among high school students - Youth Risk Behavior Survey, United States, 2021
Harper CR , Li J , Sheats K , Hertz MF , Merrill-Francis M , Friar NW , Ashley CL , Shanklin S , Barbero C , Gaylor EM , Hoots BE . MMWR Suppl 2023 72 (1) 22-28 Community violence, including homicides involving firearms, is a significant public health concern. From 2019 to 2020, firearm-related homicides increased by 39% for youths and young adults aged 10-24 years, and rates of suicide by firearm increased by approximately 15% among the same age group. Findings from the nationally representative 2021 Youth Risk Behavior Survey were used to analyze disparities and correlates of witnessing community violence and gun carrying among a nationally representative sample of high school students. Chi-square tests and logistic regression accounting for the complex sampling of the survey were used to assess demographic differences by student sex, race and ethnicity, age, and sexual identity in ever witnessing community violence, gun carrying in the past 12 months, and their associations with substance use and suicide risk. Measures of substance use included current binge drinking and marijuana use and lifetime prescription opioid misuse and illicit drug use. Suicide risk included seriously considered attempting suicide and attempted suicide in the past 12 months. Overall, approximately 20% of students witnessed community violence and 3.5% of students carried a gun. American Indian or Alaska Native, Black, and Hispanic students were more likely to witness community violence and to report carrying a gun than their White peers. Males were more likely to witness community violence and carry a gun than females. Lesbian, gay, or bisexual students were more likely to witness community violence than their heterosexual peers. Also, witnessing community violence consistently was associated with increased odds of gun carrying, substance use, and suicide risk for both males and females and when comparing Black, White, and Hispanic students. These findings highlight the importance of comprehensive violence prevention strategies that incorporate health equity to mitigate the effects of violence exposure on substance use and suicide risk among youths. |
Transformational narrative changes as a community-level approach to the prevention of adverse childhood experiences and substance use
Harper CR , Treves-Kagan S . Am J Community Psychol 2024 There is increasing scientific evidence linking substance use, childhood adversity, and social determinants of health. However, little research has considered the evaluation of community-level strategies to reduce substance use by increasing awareness and implementation of evidence-based strategies for preventing adverse childhood experiences (ACEs). This article lays out the conceptual framework for a $2.9 million demonstration project designed to raise awareness of the impact of ACEs on substance use, including primary prevention strategies. Communities used transformational narrative change-with an emphasis on the voices of those most impacted by ACEs and substance use-to highlight the importance of addressing social determinants of health along with primary prevention strategies. The conceptual background highlighted in this article informed media, public health, and local efforts in the three accompanying articles and invited commentary. These findings may help inform future efforts to promote community-level strategies and strengthen the evidence-base for transformational narrative change efforts. |
Increasing support for the prevention of adverse childhood experiences and substance use: Implementation of narrative change strategies in local health departments
Harper CR , Tan-Schriner C , Royster J , Morgan KL , Burnett V , Treves-Kagan S , Bradford J , Ettman L , Espinosa O , Marziale E . Am J Community Psychol 2024 Adverse childhood experiences (ACEs) are potentially traumatic but preventable experiences that occur before the ages of 18, including child abuse, witnessing violence, and parental substance use. ACEs have been linked with increased risk for substance use, along with a variety of other negative health outcomes. However, there is limited evidence of community-level strategies that link ACEs and substance to increase awareness of prevention efforts. This article reports on a $2.9 million program to promote health equity and inform narratives for the prevention of ACEs and substance use within three Midwestern communities. Program partners sought to create new transformational narratives that linked ACEs and substance use, while underscoring the importance of addressing social determinants of health (SDOH) that lead to disparities in ACEs and substance use. A mixed-methods evaluation design included document review, in-depth interviews with program staff (N = 8) and community liaisons (N = 2), and site reports from program staff (N = 8) and their community partners (N = 17). Analyses showed that successful implementation efforts had early leadership buy-in and support, set clear and manageable expectations at the outset of implementation, and developed strong relationships with organizations that engage in health equity work. Training and technical assistance were critical to helping community partners build trust, recognize each other's perspectives, broaden and reframe their world view, and better understand narrative efforts for the primary prevention of ACEs and substance use. |
Youth-Serving Professionals' Perspectives on HIV Prevention Tools and Strategies Appropriate for Adolescent Gay and Bisexual Males and Transgender Youth
Cahill SR , Geffen SR , Fontenot HB , Wang TM , Viox MH , Fordyce E , Stern MJ , Harper CR , Johns MM , Avripas SA , Michaels S , Mayer KH , Dunville R . J Pediatr Health Care 2020 34 (2) e1-e11 INTRODUCTION: HIV disproportionally burdens adolescent men who have sex with men (AMSM) and transgender youth. This study explores barriers and facilitators that professionals face in delivering HIV preventive services and education. METHODS: Adolescent health providers (nurse practitioners, physicians, and other), school nurses, youth workers, and school educators were recruited nationally for this qualitative study. RESULTS: Thirty-four professionals participated. Common categories identified across professional group were (1) effective strategies for building trust with youth, (2) perceived barriers/facilitators to sexual health communication, (3) perceived barriers/facilitators to effective HIV prevention, and (4) preferred content for HIV prevention tools. DISCUSSION: Key elements for developing multidisciplinary resources to support AMSM and transgender youth should include (1) web-based or easily accessible sexual health educational materials, (2) resources for referrals, (3) trainings to support competence in caring for sexual and gender minority youth, and (4) guidance for navigating policies or eliciting policy change. |
Differences in health care experiences among transgender and gender diverse youth by gender identity and race/ethnicity
Johns MM , Gordon AR , Andrzejewski J , Harper CR , Michaels S , Hansen C , Fordyce E , Dunville R . Prev Sci 2023 24 (6) 1128-1141 Transgender and gender diverse (TGD) youth experience significant risk for negative health outcomes, yet few studies exist that address TGD youth's experiences of health care. This paper explores the equitable access and utilization of health care in a sample of TGD youth of diverse gender and racial/ethnic identities. Data for this analysis are from the TGD subsample (n = 1415) of the 2018 Survey of Today's Adolescent Relationships and Transitions (START) Project. We assessed five health care experiences: being insured, having a current health care provider, being out to one's provider, believing your provider was knowledgeable about transgender issues, and barriers to accessing care due to gender identity/expression. We examined the proportion of TGD youth who reported each of these outcomes and within-group differences by gender identity and race/ethnicity using descriptive statistics, logistic regression, and predicted probabilities. When differences were examined by gender identity, barriers to equitable care were consistently more present among transgender females than youth of other gender identities. There were few significant differences by race/ethnicity; however, dual referent models demonstrated barriers to equitable care were particularly evident among Black and Hispanic transgender women. We discuss these findings through the lens of intersectionality and highlight the importance of research and intervention work focused on reducing barriers to equitable care for TGD youth. |
A systems science approach to identifying data gaps in national data sources on adolescent suicidal ideation and suicide attempt in the United States
Giabbanelli PJ , Rice KL , Nataraj N , Brown MM , Harper CR . BMC Public Health 2023 23 (1) 627 BACKGROUND: Suicide is currently the second leading cause of death among adolescents ages 10-14, and third leading cause of death among adolescents ages 15-19 in the United States (U.S). Although we have numerous U.S. based surveillance systems and survey data sources, the coverage offered by these data with regard to the complexity of youth suicide had yet to be examined. The recent release of a comprehensive systems map for adolescent suicide provides an opportunity to contrast the content of surveillance systems and surveys with the mechanisms listed in the map. OBJECTIVE: To inform existing data collection efforts and advance future research on the risk and protective factors relevant to adolescent suicide. METHODS: We examined data from U.S. based surveillance systems and nationally-representative surveys that included (1) observations for an adolescent population and (2) questions or indicators in the data that identified suicidal ideation or suicide attempt. Using thematic analysis, we evaluated the codebooks and data dictionaries for each source to match questions or indicators to suicide-related risk and protective factors identified through a recently published suicide systems map. We used descriptive analysis to summarize where data were available or missing and categorized data gaps by social-ecological level. RESULTS: Approximately 1-of-5 of the suicide-related risk and protective factors identified in the systems map had no supporting data, in any of the considered data sources. All sources cover less than half the factors, except the Adolescent Brain Cognitive Development Study (ABCD), which covers nearly 70% of factors. CONCLUSIONS: Examining gaps in suicide research can help focus future data collection efforts in suicide prevention. Our analysis precisely identified where data is missing and also revealed that missing data affects some aspects of suicide research (e.g., distal factors at the community and societal level) more than others (e.g., proximal factors about individual characteristics). In sum, our analysis highlights limitations in current suicide-related data availability and provides new opportunities to identify and expand current data collection efforts. |
Hostile home environment predicting early adolescent sexual harassment perpetration and potential school-related moderators
Espelage DL , Harper CR , Ingram KM , Basile KC , Leemis RW , Nickodem KK . J Res Adolesc 2022 33 (2) 530-546 Using family systems theory, this longitudinal study of middle school youth examined the effects of abuse, family conflict, and sibling aggression on sexual harassment perpetration (N = 1563; M(age) 11.2, 51% boys; 39% Hispanic, 29% Black, and 19% White). Boys reported more sexual harassment than girls; perpetration increased for both. The association between a hostile home environment and sexual harassment perpetration was moderated by school experiences. School belonging buffered effects of hostile home environment on baseline sexual harassment perpetration for boys who experienced abuse and White adolescents with high sibling aggression. Academic grades moderated change in perpetration over time, but effects differed by sex and race. It is important to understand how early violence exposures relate to sexual violence perpetration during early adolescence. |
Pathways to suicide or collections of vicious cycles Understanding the complexity of suicide through causal mapping
Giabbanelli PJ , Rice KL , Galgoczy MC , Nataraj N , Brown MM , Harper CR , Nguyen MD , Foy R . Soc Netw Anal Min 2022 12 (1) 1-21 Suicide is the second leading cause of death among youth ages 10–19 in the USA. While suicide has long been recognized as a multifactorial issue, there is limited understanding regarding the complexities linking adverse childhood experiences (ACEs) to suicide ideation, attempt, and fatality among youth. In this paper, we develop a map of these complex linkages to provide a decision support tool regarding key issues in policymaking and intervention design, such as identifying multiple feedback loops (e.g., involving intergenerational effects) or comprehensively examining the rippling effects of an intervention. We use the methodology of systems mapping to structure the complex interrelationships of suicide and ACEs based on the perceptions of fifteen subject matter experts. Specifically, systems mapping allows us to gain insight into the feedback loops and potential emergent properties of ACEs and youth suicide. We describe our methodology and the results of fifteen one-on-one interviews, which are transformed into individual maps that are then aggregated and simplified to produce our final causal map. Our map is the largest to date on ACEs and suicide among youth, totaling 361 concepts and 946 interrelationships. Using a previously developed open-source software to navigate the map, we are able to explore how trauma may be perpetuated through familial, social, and historical concepts. In particular, we identify connections and pathways between ACEs and youth suicide that have not been identified in prior research, and which are of particular interest for youth suicide prevention efforts. © 2022, This is a U.S. Government work and not under copyright protection in the US; foreign copyright protection may apply. |
Associations between school absence and school violence by sexual identity
Lowry R , Kennedy K , Johns MM , Harper CR , Wilkins NJ . Am J Prev Med 2022 63 (3) 384-391 INTRODUCTION: Sexual minority youth are disproportionately exposed to school violence compared with their heterosexual peers. It is unknown whether the associations between school absence and exposure to school violence vary by sexual identity. METHODS: In 2021, data were combined from the 2015, 2017, and 2019 national Youth Risk Behavior Surveys to produce nationally representative samples of U.S. high-school students who identified as gay/lesbian (n=1,061), identified as bisexual (n=3,210), were not sure of their sexual identity (n=1,696), or identified as heterosexual (n=35,819). Associations were examined between 3 school violence exposures (being threatened/injured with a weapon at school, being bullied at school, and being in a physical fight at school) and school absence due to safety concerns. In each sample, multivariable logistic regression models were used to calculate adjusted prevalence ratios adjusted for sex, race/ethnicity, grade, current substance use, being offered/sold drugs at school, feeling sad/hopeless, and suicidal thoughts. Adjusted prevalence ratios were considered statistically significant if 95% CIs did not include 1.0. RESULTS: Exposure to school violence and school absence due to safety concerns were more prevalent among sexual minority students than among heterosexual students. Associations between exposure to school violence and school absence due to safety concerns were similar across sexual identity groups. For example, school absence was associated with being threatened/injured with a weapon at school among gay/lesbian (adjusted prevalence ratio=3.00), bisexual (adjusted prevalence ratio=3.66), those not sure (adjusted prevalence ratio=4.56), and heterosexual (adjusted prevalence ratio=3.75) students. CONCLUSIONS: Associations between school absenteeism and school violence exist in each sexual identity group. Therefore, programs providing safe and supportive school environments may result in reduced absenteeism among all students. |
Protective environments, health, and substance use among transgender and gender expansive youth
Kennedy KS , Harper CR , Li J , Suarez NA , Johns MM . LGBT Health 2022 9 (6) 393-400 Purpose: Transgender and gender expansive (TGE) youth experience elevated risk for substance use and other health inequities compared to cisgender peers. The purpose of this study was to examine associations between protective environments-perceived community tolerance, perceived family support, and housing stability-and recent binge drinking, lifetime high-risk substance use (HRSU; cocaine, methamphetamines, and/or heroin), and self-rated health in a sample of TGE youth. Methods: This secondary analysis of 1567 TGE youth aged 13-24 years draws from the Centers for Disease Control and Prevention's 2018 web-based Survey of Today's Adolescent Relationships and Transitions, which used a nonprobabilistic recruiting strategy via social media. Logistic regression was used to test the associations between protective environments and substance use and health outcomes. Results: Overall, 28.1% of participants reported that people who lived near them were tolerant of transgender people, 32.8% reported that their family was at least somewhat supportive of their TGE identity, and 77.0% were stably housed. In the logistic regression models, community tolerance and housing stability were associated with lower odds of self-rated poor health. Housing stability was associated with lower odds of recent binge drinking and lifetime HRSU. Conclusion: Perceived community tolerance and housing stability were associated with several health outcomes among TGE youth in this study. Protective factors, including safe, stable, nurturing relationships and environments, are critical to youth health and wellbeing. The findings in this study highlight the need for prevention strategies to promote protective environments and reduce known substance use and overall health inequities among TGE youth. |
Overwhelming support for sexual health education in U.S. schools: A meta-analysis of 23 surveys conducted between 2000 and 2016
Szucs LE , Harper CR , Andrzejewski J , Barrios LC , Robin L , Hunt P . J Adolesc Health 2022 70 (4) 598-606 Purpose: Surveys suggest that the general public (i.e., adults or parents) supports sexual health education in schools. However, the number of schools providing sex education continues to decline in the United States. The purpose of this study is to conduct a meta-analysis of U.S.-based representative surveys to provide a pooled estimate of public support for sexual health education delivered in schools. Methods: A systematic search of three databases (Medline, PsycInfo, and ERIC) was conducted to identify survey measuring adult and parent attitudes toward sexual health education in school between 2000 and 2016. Meta-analyses were conducted in OpenMetaAnalyst via the metaphor package in R using a DerSimonian-Laird random effect models to account for heterogeneity between surveys. Results: A total of 23 citations met study inclusion and exclusion criteria, representing 15 unique probability surveys conducted with the public. Among the included surveys, 14 were nationwide and 11 included parents or an overrepresentation of parents. Across all survey findings, 88.7% (95% confidence interval = 86.2–91.2) of respondents supported sexual health education. Among surveys that only included parents or oversampled for parents, 90.0% (95% confidence interval = 86.5–93.4) supported sexual health education, and among nationally representative surveys, 87.7% (95% confidence interval = 85.1–90.6) of respondents supported sexual health education. Conclusion: These findings demonstrate overwhelming support for sexual health education delivered in schools. Additional research is needed to determine individual differences in support for specific sexual health education topics and skills delivered through classroom-based instruction. © 2021 |
Association between LGBTQ student nondiscrimination laws in selected states and school district support for gay-straight alliances
Harper CR , Johns MM , Orenstein D , Pampati S , Jones TM , Leonard S , Taylor KR , Robin L . J Adolesc Health 2022 70 (4) 584-587 PURPOSE: To examine the association between state laws protecting lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ) students and school districts' recommendations or requirements for establishing gay-straight alliances (GSAs) in schools. Beginning in fall 2013, 19 state education agencies (SEAs) engaged in HIV/STI and pregnancy prevention activities in "priority" school districts. SEAs provided support to priority districts to require or recommend GSAs in their schools. METHODS: This study used semi-annually collected program evaluation data and state law data from the Gay, Lesbian, and Straight Education Network. We assessed whether increases in the percentage of priority districts recommending or requiring schools to provide GSAs varied by the presence of nondiscrimination or enumerated antibullying laws with a difference-in-difference design. RESULTS: States with nondiscrimination laws began with more priority districts recommending or requiring schools to provide GSAs (52.5%) compared to states without laws (47.5%). We found a significant interaction (p < .01) between increases in the percentage of priority districts recommending or requiring a GSA and having a state nondiscrimination law. Across the first 3 years of program implementation, there was a 30% increase (p < .01) in priority districts recommending or requiring schools to provide GSAs in states with nondiscrimination laws, compared to a 12% increase (p < .01) in states without laws. There was no significant interaction between states with enumerated antibullying laws and districts recommending or requiring a GSA. DISCUSSION: State LGBTQ nondiscrimination laws for students may facilitate school district support of GSAs, which may decrease health risks among LGBTQ youth. |
Impact of Medicaid expansion and methadone coverage as a medication for opioid use disorder on foster care entries during the opioid crisis
Tang S , Matjasko JL , Harper CR , Rostad WL , Ports KA , Strahan AE , Florence C . Child Youth Serv Rev 2021 130 Between 2012 and 2018, incidents of opioid-involved injuries surged and the number of children in foster care due to parental drug use disorder increased. Treatments for opioid use disorder (OUD) might prevent or reduce the amount of time that children spend in the child welfare system. Using administrative data, we examined the impact of Medicaid expansion and state support for methadone as a medication for opioid use disorder (MOUD) on first-time foster care placements. Results show that first-time foster care entries due to parental drug use disorder experienced a reduction of 28 per 100,000 children in Medicaid expansion states with methadone MOUD covered by their state Medicaid programs. The largest reduction was found among non-Hispanic Black children and the youngest children (age 0–1 years). Policies that increase OUD treatment access may reduce foster care placements by reducing parents’ drug use, a risk factor for child abuse/neglect and subsequent home removal. © 2021 |
Nonvoluntary or forced sex among women, by sexual identity, attraction, and behavior - National Survey of Family Growth, United States, 2011-2017
Liu GS , Harper CR , Johns MM , Mercer Kollar LM . MMWR Morb Mortal Wkly Rep 2021 70 (38) 1326-1331 Nonheterosexual (sexual minority) women report experiencing more sexual violence than heterosexual (sexual majority) women (1,2). Sexual minority women are often categorized as a collective whole, which fails to capture the nuances in sexual violence among subgroups of sexual minority women, such as bisexual and lesbian women (3). To estimate the prevalence of lifetime forced vaginal intercourse (forced sex) and of nonvoluntary first vaginal intercourse among women aged 18-44 years in the United States, CDC analyzed data from female respondents who were interviewed during 2011-2017 for the National Survey of Family Growth (NSFG); respondents were stratified by self-reported sexual identity, attraction, and behavior. Log-binomial regressions and analyses of variance (ANOVAs) were performed to compare experiences across each dimension of sexual orientation, controlling for demographic characteristics. Compared with sexual majority women,* prevalence of any male-perpetrated nonvoluntary first vaginal intercourse or forced sex (nonvoluntary or forced sex) was higher among women who identified as bisexual (36.1% versus 17.5%), reported attraction to the opposite and same sex (30.3% versus 15.8%), and reported sexual behavior with the opposite and same sex (35.7% versus 15.9%). These sexual minority women reported that their earliest experience of nonvoluntary or forced sex occurred at younger ages than did that of sexual majority women. Among women who were unsure of their sexual attraction, the prevalence of nonvoluntary first vaginal intercourse was also higher than among sexual majority women. These findings underscore the need for comprehensive prevention approaches tailored for sexual minority women and prevention of child sexual abuse, given the average ages at earliest nonvoluntary or forced sex experience among sexual minority women (range = 12.5-16.3 years). Additional research is needed into the circumstances of and norms or attitudes that influence perpetration of nonvoluntary or forced sex and broader sexual violence against sexual minority women. Prevention of nonvoluntary or forced sex victimization among sexual minority women will require comprehensive approaches to prevent sexual violence and child sexual abuse. Engaging sexual minority women in the development of sexual violence prevention efforts and research would help ensure that the experiences of sexual minority women across the spectrum are represented. |
Transgender youth experiences and perspectives related to HIV preventive services
Fontenot HB , Cahill SR , Wang T , Geffen S , White BP , Reisner S , Conron K , Harper CR , Johns MM , Avripas SA , Michaels S , Dunville R . Pediatrics 2020 145 (4) BACKGROUND: In the United States, transgender youth are at especially high risk for HIV infection. Literature regarding HIV prevention strategies for this vulnerable, often-hidden population is scant. Before effective, population-based HIV prevention strategies may be adequately developed, it is necessary to first enhance the contextual understanding of transgender youth HIV risk and experiences with HIV preventive services. METHODS: Two 3-day, online, asynchronous focus groups were conducted with transgender youth from across the United States to better understand participant HIV risk and experiences with HIV preventive services. Participants were recruited by using online advertisements posted via youth organizations. Qualitative data were analyzed by using content analysis. RESULTS: A total of 30 transgender youth participated. The average age was 18.6 years, and youth reported a wide range of gender identities (eg, 27% were transgender male, 17% were transgender female, and 27% used >/=1 term) and sexual orientations. Four themes emerged: (1) barriers to self-efficacy in sexual decision-making; (2) safety concerns, fear, and other challenges in forming romantic and/or sexual relationships; (3) need for support and education; and (4) desire for affirmative and culturally competent experiences and interactions (eg, home, school, and health care). CONCLUSIONS: Youth discussed experiences and perspectives related to their gender identities, sexual health education, and HIV preventive services. Findings should inform intervention development to improve support and/or services, including the following: (1) increasing provider knowledge and skills to provide gender-affirming care, (2) addressing barriers to services (eg, accessibility and affordability as well as stigma and discrimination), and (3) expanding sexual health education to be inclusive of all gender identities, sexual orientations, and definitions of sex and sexual activity. |
Using the social-ecological model to improve access to care for adolescents and young adults
Harper CR , Steiner RJ , Brookmeyer KA . J Adolesc Health 2018 62 (6) 641-642 Spencer et al.'s analysis of National Health Interview Survey data between 2010 and 2016 highlights promising reductions in the number of uninsured adolescents and young adults, with pronounced declines in coverage over the course of adolescent development [1]. Insurance coverage is critically important for young people who need preventive services or face serious health issues. Recent Centers for Disease Control and Prevention data indicate that 17% of children and 21% of adolescents are obese, which is linked to chronic health effects such as diabetes, heart disease, and depression [2]. Individuals aged 15–24 account for nearly half of incident sexually transmitted infections annually, and suicide is a leading cause of death among children and adolescents [3], [4]. Across these outcomes, improving access to and utilization of health services is a critical component of prevention efforts. |
Health risks among discordant heterosexual high school students
Harper CR , Clayton HB , Andrzejewski J , Johns MM . J LGBT Youth 2018 15 (3) 1-13 Limited information exists on heterosexual youth with sexual contact with same-sex partners in the United States (i.e., discordant heterosexual). We compared the prevalence of health risks between discordant heterosexual, heterosexual with only opposite-sex sexual contact, lesbian/gay, and bisexual students using the 2015 national Youth Risk Behavior Survey (YRBS). Nationwide, 3.2% of students were identified as discordant heterosexuals. The prevalence of several risk behaviors was significantly higher among discordant heterosexual students than their heterosexual peers with only opposite-sex sexual contact. Clinicians should consider sexual identity and sex of sexual partners when conducting risk-assessments to ensure they appropriately target populations for intervention. |
Variability in condom use trends by sexual risk behaviors: Findings from the 2003-2015 National Youth Risk Behavior Surveys
Harper CR , Steiner RJ , Lowry R , Hufstetler S , Dittus PJ . Sex Transm Dis 2017 45 (6) 400-405 OBJECTIVES: To examine variability in condom use trends by sexual risk behavior among US high school students. METHODS: Data were from the 2003-2015 national Youth Risk Behavior Surveys conducted biennially among a nationally representative sample of students in grades 9-12. We used logistic regression to examine variability in trends of condom use during last sexual intercourse among female and male students by four by four sexual risk behaviors: drank alcohol or used drugs before last sexual intercourse, first sexual intercourse before age 13 years, four or more sex partners during their life, and two or more sex partners during the past three months. RESULTS: Between 2003 and 2015 significant declines in self-reported condom use were observed among black female (63.6% in 2003 to 46.7% in 2015) and white male students (69.0% in 2003 to 58.1% in 2015). Among female students, declines in self-reported condom use were significant only among those who drank or use drugs before last sexual intercourse, had four or more sex partners during their life, or two or more sex partners during the past three months. There was a significant interaction between trends in condom use and first sexual intercourse before age 13 years, suggesting more pronounced declines among female students who initiated first sexual intercourse before age 13 years than their female peers. Trends did not vary by sexual risk behavior for males. CONCLUSIONS: Results suggest that declines in self-reported condom use have occurred among female students at greater risk for acquiring a sexually transmitted disease (STD). |
School environment is related to lower health and safety risks among sexual minority middle and high school students
Ethier KA , Harper CR , Dittus PJ . J Adolesc Health 2017 62 (2) 143-148 PURPOSE: The objective of this study was to examine the relationship between school involvement and connectedness with measures of sexual risk, substance use, and experience of violence among students who had sexual contact with the same sex or with both sexes. METHODS: A sample of middle school and high school students who participated in a study conducted in a large urban school district were selected based on their reported experience of having initiated sexual activity with same-sex partners. In classroom-based surveys, we assessed self-reported involvement in school-based activities and feelings of school connectedness, as well as self-reported sexual risk, substance use, and experience of violence. RESULTS: Significant protective associations were found between school involvement and lifetime alcohol and marijuana use, and between school connectedness and ever having been in a fight, feeling safe at school, and drug use other than marijuana (all p < .05). CONCLUSIONS: Findings suggest that efforts to increase school involvement and connectedness provide a starting point for addressing significant health and safety concerns among students with same-sex sexual activity. |
Structural intervention with school nurses increases receipt of sexual health care among male high school students
Dittus PJ , Harper CR , Becasen JS , Donatello RA , Ethier KA . J Adolesc Health 2017 62 (1) 52-58 PURPOSE: Adolescent males are less likely to receive health care and have lower levels of sexual and reproductive health (SRH) knowledge than adolescent females. The purpose of this study was to determine if a school-based structural intervention focused on school nurses increases receipt of condoms and SRH information among male students. METHODS: Interventions to improve student access to sexual and reproductive health care were implemented in six urban high schools with a matched set of comparison schools. Interventions included working with school nurses to improve access to sexual and reproductive health care, including the provision of condoms and information about pregnancy and sexually transmitted disease prevention and services. Intervention effects were assessed through five cross-sectional yearly surveys, and analyses include data from 13,740 male students. RESULTS: Nurses in intervention schools changed their interactions with male students who visited them for services, such that, among those who reported they went to the school nurse for any reason in the previous year, those in intervention schools reported significant increases in receipt of sexual health services over the course of the study compared with students in comparison schools. Further, these results translated into population-level effects. Among all male students surveyed, those in intervention schools were more likely than those in comparison schools to report increases in receipt of sexual health services from school nurses. CONCLUSIONS: With a minimal investment of resources, school nurses can become important sources of SRH information and condoms for male high school students. |
Changes in the distribution of sex partners in the United States: 2002 to 2011-2013
Harper CR , Dittus PJ , Leichliter JS , Aral SO . Sex Transm Dis 2017 44 (2) 96-100 OBJECTIVE: The purpose of the current analysis is to examine subgroup differences in the distribution of opposite-sex sex partners in the United States across an approximate 10-year period to identify patterns that may inform sexually transmitted infection research and prevention. METHODS: Data were drawn from the 2002 and 2011-2013 National Survey of Family Growth, a US probability-based household survey focusing on sexual and reproductive health. The measures included in this analysis were lifetime opposite-sex sex partners and opposite-sex sex partners in the past year. Analyses were conducted separately for men and women. All analyses were conducted in R and R-studio with the "survey" package, focusing on medians, the 80th, and 95th quartile. RESULTS: In 2002, there were significant differences between men and women in median number of lifetime sex partners with men reporting more lifetime partners. However, in the 2011-2013 data, these differences are no longer significant. Still, the findings suggest that the top 20% and top 5% of men are reporting significantly more lifetime partners than their female counterparts. In comparison, partners in the past year remain relatively unchanged for both men and women. CONCLUSIONS: These findings suggest that there were important changes in the distribution of sex partners between 2002 and 2011-2013 that have implications for sexually transmitted infection prevention. Median lifetime partners are no longer different for women and men: however, the distribution of lifetime partners among men is becoming even more skewed. |
The longitudinal impact of perceptions of parental monitoring on adolescent initiation of sexual activity
Ethier KA , Harper CR , Hoo E , Dittus PJ . J Adolesc Health 2016 59 (5) 570-576 PURPOSE: The association between parental monitoring and adolescent behavior is well established. Past research suggests that parents monitor adolescent activities through parental control, solicitation of information, and youth disclosure, which increase parents' knowledge of youth activity leading to decreased risk behavior. However, there is mixed evidence of the impact of these efforts on sexual behavior. We examined these strategies from the adolescent perspective and assessed their impact on the initiation of sexual activity across the transition from middle school to high school. METHODS: Analyses include 533 primarily Latino adolescents, who had not yet had sex in eighth grade and were surveyed yearly through 10th grade. RESULTS: Adolescents who in eighth grade reported greater parental knowledge and more family rules about dating were less likely to initiate sex between eighth and 10th grade. Exchange of information, through parental solicitation and youth disclosure, and parental control, through rules about friends and dating, as well as maternal relationship satisfaction were significant predictors of parental knowledge. There were no gender differences in the impact of dating rules and parental knowledge on sexual initiation, but the paths to acquiring knowledge did differ by gender. CONCLUSIONS: Results suggest that parental monitoring at earlier ages has an impact on sexual initiation. Effective monitoring is an active process within a family that includes setting boundaries and exchanging information. Interventions that encourage family rules, provide strategies for improving parental solicitation of information, and increase youth disclosure by enhancing the maternal-child relationship may be more likely to impact sexual initiation. |
High school students' self-reported use of school clinics and nurses
Harper CR , Liddon N , Dunville R , Habel MA . J Sch Nurs 2016 32 (5) 324-8 Access to school health clinics and nurses has been linked with improved student achievement and health. Unfortunately, no studies have examined how many students report using school clinics or nurses and for which services. This study addressed this gap with data from a nationally representative sample of 15- to 25-year-olds. Respondents who reported being in high school were provided a list of services and asked whether they had gone to a school nurse or clinic for any of the listed services. Nearly 90% reported having access to a school clinic or nurse. Among students with access, 65.6% reported using at least one service. Non-White students and younger students were more likely to report having access to a clinic or nurse. These results show many students have access to clinics or nurses and are using these services, although not uniformly for all services. |
