Undermining the Translational Potential of Clinical Research with Adolescents and Young Adults: Differential Enrollment in Randomized Clinical Trials During COVID-19.

BACKGROUND: COVID-19 stay-at-home orders and research restrictions halted recruitment and follow-up of clinical research patients. While clinical research has resumed, it is an open question whether research participation has returned to levels similar to those before COVID-19. METHODS: We utilized data from the TECH-PN (NCT# NCT03828994) study, a single-center RCT enrolling 13-25-year-olds with mild-moderate pelvic inflammatory disease (PID) receiving ambulatory care. We examined enrollment patterns before COVID-19 and during/after COVID-19 among those assessed for eligibility by estimating the average rate of recruitment visits for each period. We focused on this monthly rate by pandemic status, the length of stay (LOS) by pandemic status, as well as the relationship between the LOS and patient demographics. Descriptive analyses were conducted, including Student's t-test to compare rates between time periods and a Chi-square test to compare the proportion refusing enrollment. RESULTS: The monthly enrollment rate during/post-pandemic was significantly lower than before COVID-19 (4.8 per month compared to 7.4 per month, p < 0.001). However, eligible participants' age, race, and insurance type were similar pre- and during/post-pandemic. Among eligible patients, LOS for receiving PID care was slightly increased, from a median of 5.4 hours to 6.4 hours (p = 0.650), and the rate of refusal to participate among those eligible was similar (23% versus 27%, p = 0.362). There was a similar number of ineligible patients due to inpatient admissions during both periods. CONCLUSION: COVID-19 pandemic restrictions negatively impacted recruitment into this RCT. Enrollment differences may reflect ongoing perceptions of restrictions in care access or a hesitancy to use health services. More research is needed to stabilize access to ambulatory STI/PID care and access to clinical trials.

Engaging caregivers to prevent substance use by at-risk adolescents in pediatric primary care.

PURPOSE OF REVIEW: Improving adolescent substance use prevention and treatment is an urgent public health priority in the United States. Current intervention models do not address how adolescents with a history of caregiver substance use are at particular risk for problematic substance use. We, therefore, reviewed the evidence on adolescent substance use prevention programs integrating caregiver-focused components and propose opportunities to incorporate adaptations of existing programs into pediatric primary care to improve outcomes for at-risk adolescents exposed to caregiver substance use. RECENT FINDINGS: There are multiple evidence-based universal prevention programs that target adolescent substance use and incorporate caregivers; however, these programs do not address the specific concerns of caregivers with substance use. Caregiver-focused programs efficaciously address family and child risk factors for adolescent substance use but are not accessible to many families and have not been longitudinally studied to assess impact on adolescent substance use. SUMMARY: Adaptation of existing prevention programs to pediatric primary care settings may open opportunities to improve engagement of families with caregiver substance use in targeted prevention strategies. Family Screening, Brief Intervention, and Referral to Treatment (F-SBIRT) is one model that can be incorporated into pediatric primary care to contextualize evidence-based practices to address substance use in a family-focused approach. To develop F-SBIRT, further research is needed to validate caregiver-focused screening tools, determine brief intervention (BI) best practices, and adapt existing evidence-based and caregiver-focused adolescent prevention programs for use with caregivers with substance use in pediatric primary care settings.

Cash Transfers and After-School Programs: A Randomized Controlled Trial for Young Men at Risk of Violence Exposure in Wilmington, Delaware.

We conducted a randomized controlled trial to determine whether an after-school program paired with a cash transfer (a conditional cash transfer) or a cash transfer alone (an unconditional cash transfer) can help improve health and economic outcomes for young men between the ages of 14 and 17 whose parents have low incomes and who live in neighborhoods with high crime rates. We find that receiving the cash transfer alone was associated with an increase in healthy behaviors (one of our primary outcome composite measures) and that the cash transfer paired with after-school programming was associated with an improvement in the financial health of participants (one of our secondary outcome composite measures). We find no differences in spending on alcohol, marijuana, cigarettes, or other drugs between either the treatment group and the control group. Neither the cash transfer alone nor the programming plus cash transfer had statistically significant effects on our other primary composite measures (physical and mental health or school attendance and disciplinary actions), or our other secondary composite measures (criminal justice engagement or social supports) but in most cases, confidence intervals were too large to rule out meaningful effects. Results suggest that cash transfers hold promise to improve the health of youth without any indication of any adverse effects.

Family-Focused Universal Substance Use Prevention in Primary Care: Advancing a Pragmatic National Healthcare Agenda.

This article advances ideas presented at a National Academies of Sciences, Engineering, and Medicine workshop in 2022 that highlighted clinical practice and policy recommendations for delivering universal, family-focused substance use preventive interventions in pediatric primary care. Pediatric primary care is a natural setting in which to offer families universal anticipatory guidance and links to systematic prevention programming; also, several studies have shown that offering effective parenting programs in primary care is feasible. The article describes a blueprint for designing a pragmatic national agenda for universal substance use prevention in primary care that builds on prior work. Blueprint practice schematics leverage efficacious family-focused prevention programs, identify key program implementation challenges and resources, and emphasize adopting a core element approach and utilizing digital interventions. Blueprint policy schematics specify avenues for improving cross-sector policy and resource alignment and collaboration; expanding, diversifying, and strengthening the prevention workforce; and enhancing financing for family-focused prevention approaches. The article then draws from these schematics to assemble a candidate universal prevention toolkit tailored for adolescent patients that contains four interlocking components: education in positive parenting practices, parent and youth education in substance use risks, a parent-youth structured interaction task, and parent and youth linkage to in-person and web-based prevention resources.

Investigating the Relative Influence of Romantic Sex Partners and Close Friends on Adolescent Alcohol and Marijuana Use.

A large body of research has identified peer exposure as a key factor driving adolescent substance use. However, findings on the role of sex partners are less robust and mixed. This study aims to fill this gap by examining the independent contribution of close friends' and sex partners' alcohol and marijuana use on adolescents' use of these substances. A secondary data analysis of social network data collected in 2000-2002 from a household sample of African American youth (14-19 years old) in the Bayview and Hunter's Point neighborhoods of San Francisco was conducted. Index participants and their nominated close friends and romantic sex partners (N = 104 triads) self-reported recent alcohol and marijuana use (defined as any use in the past 3 months). Generalized estimated equations were used to estimate the independent association between adolescent's recent substance use and their friend's and sex partner's use. Adolescents with a marijuana-using romantic sex partner had a nearly six-fold higher odds of using marijuana compared to adolescents with a non-using partner, controlling for close friend's marijuana use and other confounders [OR:5.69, 95%CI: 1.94, 16.7]; no association with close friend's marijuana use was found. A similar pattern was observed for alcohol use. Adolescents with an alcohol-using romantic sex partner had increased odds of using alcohol compared to adolescents with a non-using partner, controlling for close friend's alcohol use and other confounders [OR:2.40, 95%CI: 1.02, 5.63]; no association with close friend's alcohol use was found. Romantic sex partners may play a unique and significant role in adolescent substance use. Peer-focused interventions may be more effective if they consider romantic sex partners. Future research should consider the role of romantic sex partners in changing social context related to substance use from adolescence to young adulthood.

State of the Art in Substance Use Prevention and Early Intervention: Applications to Pediatric Primary Care Settings.

With changes to drug-related policies and increased availability of many drugs, we currently face a public health crisis related to substance use and associated health consequences. Substance use and substance use disorders (SU/SUDs) are complex developmental disorders with etiologies that emerge through the intergenerational transmission of biological, familial, and environmental factors. The family ecosystem both influences and is influenced by SU/SUDs, particularly in children and adolescents. Family dynamics and parent functioning and behaviors can represent either risk or protective factors for the development of SU/SUDs in children. Primary care providers who provide care for children, adolescents, and families are in an ideal position to deliver prevention messages and to intervene early in the development of substance misuse and SUD among their patients. Despite recommendations from the American Academy of Pediatrics, few pediatric primary care providers provide anticipatory guidance to prevent or screen for substance misuse. Many barriers to those practices can be overcome through the integration and application of findings from the field of prevention science and the many lessons learned from the implementation of evidence-based interventions. Consideration of the implications of prevention science findings would help clarify the relevant roles and responsibilities of the primary care clinician, and the benefit of referral to and consultation from addiction specialists. Additionally, the past decade has seen the development and validation of a continuum of evidence-based prevention and early SU/SUD intervention activities that can be adapted for use in primary care settings making wide-spread implementation of prevention feasible. We propose a paradigm shift away from a model based on diagnosis and pathology to one upstream, that of family-focused prevention and early intervention. Adapting and scaling out empirically based prevention and early SU/SUD interventions to primary care settings and removing barriers to collaborative care across primary care, addiction medicine, and mental health providers offer the potential to meaningfully impact intergenerational transmission of SU/SUD - addressing a leading health problem facing our nation.

Understanding caregiver acceptance of screening for family substance use in pediatric clinics serving economically disadvantaged children.

Background: Children of parents with substance use disorders are at greater risk for mental and physical health co-morbidities. Despite guidelines, pediatricians rarely screen for substance use in the family/household, citing fear of offending parents. The objectives of this study were to examine (1) caregiver acceptance of pediatricians screening for family/household substance use during well-child visits, (2) prevalence of family/household substance use, and (3) the association between family/household substance use and trust in their child's pediatrician. Methods: This cross-sectional study surveyed adult caregivers presenting a child for medical care at two urban pediatric outpatient clinics using a brief anonymous computer-based survey. The primary outcome measured the acceptability of pediatrician screening for family/household substance use. Substance use and concerns about use in the family/household were also assessed. Results: Adult caregivers (n = 271) surveyed were mean age 35 years, 73% mothers, 90% African American, and 85% on Medicaid. Over half (51%) of caregivers reported substance use by someone in the family/household, most commonly cigarettes (38%), followed by alcohol (19%) and marijuana (10%). Sixty-one percent of caregivers who reported family substance use expressed concern about the use of this substance. The majority (87%) agreed it is appropriate for pediatricians to ask caregivers about family/household substance use. No differences were found between caregivers who did and did not report substance use in their family/household. Caregivers with concerning substance use in their family/household were less likely to trust their pediatrician [OR = 0.21, 95%CI: 0.05, 0.85] Conclusions: Caregivers endorsed acceptance of universal screening for substance use, including illicit substances, and substance use disorders in the family/household during well-child visits. Pediatricians are trusted professionals with expertise in communicating with parents to maximize the health of their patients; assessing family history of substance use and substance use disorders is a natural extension of their role.

A systems framework depicting how complex neighborhood dynamics and contextual factors could impact the effectiveness of an alcohol outlet zoning policy.

An updated zoning policy eliminating all alcohol outlets (liquor stores) in residential districts was implemented to reduce high rates of violent crime in Baltimore City. Diverse stakeholders were engaged in group model building (GMB) activities to develop causal loop diagrams (CLDs) that elucidate the impact of the new zoning policy on crime, and more broadly, the potentially unintended social and environmental consequences of the policy. Three distinct groups, community advocates, city officials/academics, and community residents, participated in three separate GMB sessions. Three CLDs, one from each stakeholder group, were created to depict the possible outcomes of the zoning policy. Our findings offer insight into potential unintended consequences of removing liquor stores from residential areas that may undermine the policy. Community members described the need for additional supports related to mental health and substance use, opportunities for investment in the community, access to other goods and services, and community-police relations to ensure the policy achieved its intended goal of reducing violent crime. Our findings highlight the importance of timely engagement of local stakeholders to understand how complex neighborhood dynamics and contextual factors could impact the effectiveness of a zoning policy change.

Using Innovation to Address Adolescent and Young Adult Health Disparities in Pelvic Inflammatory Disease: Design of the Technology Enhanced Community Health Precision Nursing (TECH-PN) Trial.

New approaches to pelvic inflammatory disease (PID) care among adolescents and young adults (AYAs) that optimize self-care and personalize treatment are warranted to address age and racial-ethnic PID-related health disparities. Here we describe the 13-month preliminary feasibility and acceptability outcomes of recruitment, retention, and intervention delivery for Technology Enhanced Community Health Precision Nursing (TECH-PN) randomized controlled trial. Urban AYAs 13-25 years assigned female sex at birth with acute mild-moderate PID provided baseline and follow-up interview data and vaginal specimens for sexually transmitted infection (STI), cytokine, and microbiota assessment. All participants received medications and text-messaging support. Participants were block randomized to either control or intervention. Control participants received 1 community nursing visit with self-management for interim care per national guidelines. Intervention participants received unlimited precision care services driven by interim STI and macrolide resistance testing results by an advanced practice provider. In the first 13 months, 75.2% patients were eligible, and 76.1% of eligible patients enrolled. Of the participants, 94% completed the intervention and 96%, 91%, and 89%, respectively, completed their 14-, 30-, and 90-day visits. Baseline laboratory results revealed infection rates that were highest for Mycoplasma genitalium (45%) followed by Chlamydia trachomatis (31%). Preliminary enrollment, STI, intervention delivery, and retention data demonstrate the feasibility and acceptability of the TECH-PN intervention and support rationale for precision care for PID among urban AYAs.

Individual and Neighborhood Factors Associated With Sexual Behavior Classes in an Urban Longitudinal Sample.

BACKGROUND: This study aimed to increase understanding of the clustering of sexual behaviors in an urban sample of emerging adults, and the individual and neighborhood factors associated with sexual behavior patterns to provide insight into reducing the disproportionate burden of poor sexual outcomes among urban African Americans. METHODS: We draw on 2 cohorts of urban, predominantly African American youth first assessed at age 6 years and follow-up to emerging adulthood (mean age, 20 years; n = 1618). Latent class analyses by gender identified co-occurrence of sexual behavior. RESULTS: We found 3 classes for both males and females: high-risk (13% of males, 15% of females), low-risk (54% of males, 56% of females) and no-risk (33% of males, 29% of females). Membership in the high-risk class was associated with school dropout, a substance use disorder diagnosis, having a criminal arrest, pregnancy, and sexually transmitted diseases for both males and females. High-risk females also had higher rates of depression. Low-risk males and females also had elevated risk of pregnancy and parenthood. Neighborhood factors distinguished the high- and no-risk classes for males and females, including the neighborhood environment scale, which assessed poverty, safety, drug activity, and crime/violence in the neighborhood. Neighborhood religiosity was inversely associated with membership in the high-risk class compared with the no-risk class for females only. Neighborhood racism distinguished those in the high-risk class compared with the no-risk class for males. CONCLUSIONS: Future work should take into account the clustering of sexual risk behaviors. Specific neighborhood factors could be addressed to reduce sexual health disparities.

Evolution of the knowledge system for agricultural development in the Yaqui Valley, Sonora, Mexico.

Knowledge systems-networks of linked actors, organizations, and objects that perform a number of knowledge-related functions that link knowledge and know how with action-have played a key role in fostering agricultural development over the last 50 years. We examine the evolution of the knowledge system of the Yaqui Valley, Mexico, a region often described as the home of the green revolution for wheat, tracing changes in the functions of critical knowledge system participants, information flows, and research priorities. Most of the knowledge system's key players have been in place for many decades, although their roles have changed in response to exogenous and endogenous shocks and trends (e.g., drought, policy shifts, and price trends). The system has been agile and able to respond to challenges, in part because of the diversity of players (evolving roles of actors spanning research-decision maker boundaries) and also because of the strong and consistent role of innovative farmers. Although the agricultural research agenda in the Valley is primarily controlled from within the agricultural sector, outside voices have become an important influence in broadening development- and production-oriented perspectives to sustainability perspectives.

Linking knowledge with action in the pursuit of sustainable water-resources management.

Managing water for sustainable use and economic development is both a technical and a governance challenge in which knowledge production and sharing play a central role. This article evaluates and compares the role of participatory governance and scientific information in decision-making in four basins in Brazil, Mexico, Thailand, and the United States. Water management institutions in each of the basins have evolved during the last 10-20 years from a relatively centralized water-management structure at the state or national level to a decision structure that involves engaging water users within the basins and the development of participatory processes. This change is consistent with global trends in which states increasingly are expected to gain public acceptance for larger water projects and policy changes. In each case, expanded citizen engagement in identifying options and in decision-making processes has resulted in more complexity but also has expanded the culture of integrated learning. International funding for water infrastructure has been linked to requirements for participatory management processes, but, ironically, this study finds that participatory processes appear to work better in the context of decisions that are short-term and easily adjusted, such as water-allocation decisions, and do not work so well for longer-term, high-stakes decisions regarding infrastructure. A second important observation is that the costs of capacity building to allow meaningful stakeholder engagement in water-management decision processes are not widely recognized. Failure to appreciate the associated costs and complexities may contribute to the lack of successful engagement of citizens in decisions regarding infrastructure.

Weekly variations in feelings of trust predict incident STI within a prospective cohort of adolescent women from a US city.

OBJECTIVES: Feelings of intimacy, perceptions of partner concurrency (PPC) and perceptions of risk for an STD (PRSTD) are meaningful and dynamic attributes of adolescent sexual relationships. Our objective was to examine whether variations in these STI-associated feelings and perceptions predicted incident Chlamydia trachomatis and/or Neisseriagonorrhoeae infection within a prospective cohort of urban adolescent women. METHODS: A cohort of clinic-recruited women aged 16-19 completed daily surveys on feelings and risk perceptions about each current sex partner on a smartphone continuously for up to 18 months. Urine was tested for C. trachomatis and N. gonorrhoeae every 3 months. Daily responses were averaged across the week. As overall means for trust, closeness and commitment were high, data were coded to indicate any decrease in feelings from the previous week. PRSTD and PPC were reverse coded to indicate any increase from the previous week. An index was created to examine the cumulative effect of variation in these feelings and perceptions. Generalised linear models were used to account for correlation among repeated measures within relationships. RESULTS: For each week that there was a decrease in trust, there was a 45% increase in the risk of being infected with an STI at follow-up (relative risk (RR) 1.45, 95% CI 1.18 to 1.78, P=0.004). Neither a decrease in closeness or commitment, nor an increase in PRSTD or PPC was associated with an STI outcome. Cumulatively, the index measure indicated that a change in an additional feeling or perception over the week increased the odds of an STI by 14% (RR 1.14, 95% CI 1.02 to 1.29, P=0.026). CONCLUSIONS: A decrease in feelings of trust towards a main partner may be a more sensitive indicator of STI risk than PRSTD, PPC or commitment. The next generation of behavioural interventions for youth will need strategies to address feelings of intimacy within adolescent romantic relationships.

The Interaction of Sexual Validation, Criminal Justice Involvement, and Sexually Transmitted Infection Risk Among Adolescent and Young Adult Males.

BACKGROUND: Young men who have been involved with the criminal justice system are more likely to have concurrent sexual partners, a key driver of sexually transmitted infections. The value men place on having sexual relationships to validate themselves may play an important role in understanding this association. METHODS: Data were from a household survey. Young men (N = 132), aged 16 to 24 years, self-reported whether they ever spent time in jail or juvenile detention and if they had sexual partnerships that overlapped in time. A novel scale, "Validation through Sex and Sexual Relationships" (VTSSR) assessed the importance young men place on sex and sexual relationships (α = 0.91). Weighted logistic regression accounted for the sampling design. RESULTS: The mean (SD) VTSSR score was 23.7 (8.8) with no differences by race. Both criminal justice involvement (CJI) (odds ratio [OR], 3.69; 95% confidence interval [CI], 1.12-12.1) and sexual validation (OR, 1.10; 95% CI, 1.04-1.16) were associated with an increased odds of concurrency; however, CJI did not remain associated with concurrency in the fully adjusted model. There was effect modification, CJI was associated with concurrency among those who scored high on sexual validation (OR, 9.18; 95% CI, 1.73-48.6]; however, there was no association among those who scored low on sexual validation. Racial differences were observed between CJI and concurrency, but not between sexual validation and concurrency. CONCLUSIONS: Sexual validation may be an important driver of concurrency for men who have been involved with the criminal justice system. Study findings have important implications on how sexual validation may explain racial differences in rates of concurrency.

Developmental Patterns of Adolescent Marijuana and Alcohol Use and Their Joint Association with Sexual Risk Behavior and Outcomes in Young Adulthood.

Urban populations disproportionately experience poor sexual outcomes, including high rates of teenage pregnancy and sexually transmitted infections. However, the contribution of substance use across adolescence to poor sexual outcomes in young adulthood has not been investigated in depth, despite offering opportunities for more targeted prevention. This study aimed to estimate joint trajectories of adolescent alcohol and marijuana use to determine if they relate differently to four sexual outcomes: multiple sexual partners, sex without a condom, teenage pregnancy, and contraction of a sexually transmitted infection in young adulthood (by age 25). Data came from a longitudinal study of urban youth followed from age 6 to age 25, with annual assessments during adolescence and young adulthood (n = 608). The sample showed high levels of sexual risk, with young adults on average having sex without a condom once in the past month, 28.5% having multiple sexual partners in the past month, one quarter having contracted a sexually transmitted infection, and over 60% of the women being pregnant as a teenager and 36% of the men having gotten a partner pregnant. Applying longitudinal latent profile analysis to estimate joint trajectories of alcohol and marijuana use from grades 8-12, we identified four classes representing high dual use, moderate alcohol use, moderate alcohol use with increasing marijuana use, and non-use. Class membership differently predicted all four outcomes investigated with high dual users having the highest level of teenage pregnancy and the increasing marijuana trajectory having the highest risk of engaging with multiple sexual partners in the past month. Results suggest implications for both sexual risk and substance use prevention for urban youth.

Trait Mindfulness and Progression to Injection Use in Youth With Opioid Addiction.

BACKGROUND: Many youth initiate opioid misuse with prescription opioids and transition over time to more severe substance-using behaviors, including injection. Trait mindfulness is a potentially protective factor. OBJECTIVES: This is a cross-sectional study characterizing a sample of opioid-using youth by level of mindfulness and examines the potential effect modification of emotion regulation on the relationship between mindfulness and progression to injection opioid use. METHODS: A convenience sample of 112 youth (ages 14-24) was recruited during an episode of inpatient detoxification and residential treatment for opioid use disorders. We examined emotion regulation (Difficulties in Emotion Regulation Scale), mindfulness (Child Acceptance and Mindfulness Measure), and opioid use. We completed multivariable regressions stratified by degree of emotion regulation looking at relationship of mindfulness on time to injection use from age of first prescription opioid. RESULTS: Youth had difficulties in emotion regulation (m = 104.2; SD = 2.41) and low mindfulness (m = 19.1;SD = 0.59). While we found overall that mindfulness was associated with time to progression to injection opioid use, there was significant effect modification. Among youth with high levels of difficulty in emotion regulation, those with high mindfulness trait had quicker progressions to injection (-1.31 years; p =.003). In contrast, youth with normal emotion regulation and high mindfulness trait had a slower progression to injection (1.67 years; p =.041). Conclusion/Importance: Our study showed a majority of youth presenting with opioid use disorders have impairments in emotion regulation and deficits in trait mindfulness. The relationship between mindfulness and opioid use is impacted by emotion regulation capacity. More research is needed to understand the various facets of mindfulness and how they interact with emotion regulation in youth.

Internal medicine resident knowledge, attitudes, and barriers to naloxone prescription in hospital and clinic settings.

BACKGROUND: The United States is facing an epidemic of opioid use and misuse leading to historically high rates of overdose. Community-based overdose education and naloxone distribution has effectively trained lay bystanders to recognize signs of overdose and administer naloxone for reversal. There has been a movement to encourage physicians to prescribe naloxone to all patients at risk of overdose; however, the rate of physician prescribing remains low. This study aims to describe resident knowledge of overdose risk assessment, naloxone prescribing practices, attitudes related to naloxone, and barriers to overdose prevention and naloxone prescription. METHODS: The HOPE (Hospital-based Overdose Prevention and Education) Initiative is an educational campaign to teach internal medicine residents to assess overdose risk, provide risk reduction counseling, and prescribe naloxone. As part of a needs assessment, internal medicine residents at an academic medical center in Baltimore, Maryland, were surveyed in 2015. Data were collected anonymously using Qualtrics. RESULTS: Ninety-seven residents participated. Residents were overwhelmingly aware of naloxone (80%) and endorsed a willingness to prescribe (90%). Yet despite a high proportion of residents reporting patients in their panels at increased overdose risk (79%), few had prescribed naloxone (15%). Residents were willing to discuss overdose prevention strategies, although only a minority reported doing so (47%). The most common barriers to naloxone prescribing were related to knowledge gaps in how to prescribe and how to assess risk of overdose and identify candidates for naloxone (52% reporting low confidence in ability to identify patients who are at risk). CONCLUSIONS: Medicine residents are aware of naloxone and willing to prescribe it to at-risk patients. Due to decreased applied knowledge and limited self-efficacy, few residents have prescribed naloxone in the past. In order to improve rates of physician prescribing, initiatives must help physicians better assess risk of overdose and improve prescribing self-efficacy.

Is the Association between Neighborhood Drug Prevalence and Marijuana use Independent of Peer Drug and Alcohol Norms? Results from a Household Survey of Urban Youth.

To inform policy debates surrounding marijuana decriminalization and add to our understanding of social and structural influences on youth drug use, we sought to determine whether there was an independent association between neighborhood drug prevalence and individual-level marijuana use after controlling for peer drug and alcohol norms. We analyzed cross-sectional data from a household survey of 563 youth aged 15-24 in Baltimore, Maryland. The study population was 88 % African-American. Using gender-stratified, weighted, multilevel logistic regression, we tested whether neighborhood drug prevalence was associated with individual-level marijuana use after controlling for peer drug and alcohol norms. Bivariate analyses identified a significant association between high neighborhood drug prevalence and marijuana use among female youth (AOR = 1.76, 95% CI = 1.26, 2.47); the association was in a similar direction but not significant among male youth (AOR = 1.26, 95% CI = 0.85, 1.87). In multivariable regression controlling for peer drug and alcohol norms, high neighborhood drug prevalence remained significantly associated among female youth (AOR = 1.59, 95% CI = 1.12, 2.27). Among male youth, the association was attenuated toward the null (AOR = 0.95, 95% CI = 0.63, 1.45). In the multivariable model, peer drug and alcohol norms were significantly associated with individual-level marijuana use among female youth (AOR = 1.54, 95% CI = 1.17, 2.04) and male youth (AOR = 2.59, 95% CI = 1.65, 4.07). This work suggests that individual-level marijuana use among female youth is associated with neighborhood drug prevalence independent of peer norms. This finding may have important implications as the policy landscape around marijuana use changes.

Young low-income ethnic minority children watch less television when their mothers regulate what they are viewing.

AIM: Parenting practices can reduce how much television (TV) children watch. This study evaluated the longitudinal association between maternal regulation of TV content and the amount of TV watched by low-income ethnic minority children. METHODS: This was a secondary data analysis of the Welfare, Children & Families: A Three City Study. Data were used from ethnic minority mothers with a child from birth to 4 years old, collected over two waves approximately 16 months apart. The dependent variable was the amount of TV watched by the child (wave two). The main independent variable was the maternal regulation of TV content (wave one). Using multiple linear regression, we evaluated the relationship between maternal regulation of TV content and the amount of TV watched by the child, adjusting for covariates. RESULTS: Of the 835 mothers, 71% were high content regulators and 8% reported no content regulation. Children whose mothers reported no regulation watched more TV approximately 16 months later than those whose mothers reported high regulation of content (ß = 0.91, 95% CI: 0.09-1.73). CONCLUSION: Our findings suggest that regulating content influences viewing amounts in young children approximately 16 months later. Interventions focused on heightening parental regulation of content may improve content and diminish viewing amounts.
