RESUMEN
For African American emerging adult men, developmental challenges are evident in their escalating substance abuse and depressive symptoms; this is particularly true for men from low-resource communities. The present study tests a developmental model linking childhood adversity and contemporaneous contextual stressors to increases in emerging adults' substance use and depressive symptoms, indirectly, via increases in defensive/hostile relational schemas and social developmental risk factors (e.g., risky peers and romantic partners, lack of involvement in school or work). We also advance exploratory hypotheses regarding DNA methylation in the oxytocin receptor gene (OXTR) as a moderator of the effects of stress on relational schemas. Hypotheses were tested with three waves of data from 505 rural African American men aged 19-25 years. Adverse childhood experiences predicted exposure to emerging adult contextual stressors. Contextual stressors forecast increases in defensive/hostile relational schemas, which increased social developmental risk factors. Social developmental risk factors proximally predicted increases in substance abuse and depressive symptoms. OXTR DNA methylation moderated the effects of contextual stressors on defensive/hostile relational schemas. Findings suggest that early exposures to stress carry forward to affect the development of social developmental risk factors in emerging adulthood, which place rural African American men at risk for increased substance abuse and depressive symptoms during the emerging adult years.

BACKGROUND:: Nonmedical prescription stimulant (NPS) use is a growing problem in Europe. Poor mental health and lack of academic engagement are potent sources of risk for substance use. Studies suggest that considerable heterogeneity may characterize the risk profiles of NPS users. To understand better the potential profiles of risk that characterize NPS users, we conducted a latent profile analysis (LPA) to document subgroups of users based on their mental health and academic engagement. METHODS:: A nationally representative, cross sectional survey of Icelandic youth was analyzed. The sample included 584 (5% of the sample) older adolescent students participating in a national study in Iceland who reported lifetime NPS use. RESULTS:: Three subgroups of NPS users emerged from our analyses. The largest subgroup (43.1%) we labeled mentally healthy achievers; youth who appear to be academically motivated and have few if any mental health concerns. The second largest group (40.4%), low achievers, resembled a typical profile for drug users in that they reported low or modest academic engagement and moderate levels of mental health concerns. The third group, anxious achievers (16.5%) appears to represent youth who felt academics were very important, had moderate study motivation, and also reported elevated mental health concerns, especially anxiety. CONCLUSIONS:: LPA revealed considerable heterogeneity among these users. Group membership suggests distinct approaches to prevention to address heterogeneity in motivations for NPS use.

PURPOSE: Rural Black men experience escalating rates of binge drinking during emerging adulthood. We hypothesized that exposure to racial discrimination would predict growth in their binge-drinking trajectories and that protective parenting, including emotional and instrumental support and high expectations for success, would attenuate the influence of racial discrimination on growth in binge drinking. METHODS: Hypotheses were tested with 3 waves of data from 505 men (ages 20.3, 21.9, and 23.1) participating in the African American Men's Project. Conditional and multigroup latent growth curve models (LGCMs) were implemented using Mplus. RESULTS: LGCM indicated that binge-drinking frequency increased linearly across time; exposure to racial discrimination at baseline predicted growth in binge drinking (ß = 0.19, p < 0.01). Multigroup comparison procedures indicated significant moderation by protective parenting. When protective parenting was high, racial discrimination had no significant influence on rates of young men's binge drinking (ß = 0.01, p = 0.51). In contrast, when protective parenting was low, the influence of discrimination was heightened (ß = 0.21, p < 0.01). CONCLUSIONS: Racial discrimination is a pernicious stressor that contributes to increases in binge drinking among young Black men. When parents engaged in emotionally and instrumentally supportive parenting, however, racial discrimination had little influence on binge-drinking trajectories during emerging adulthood. Study findings underscore the importance of the emerging adult transition as a period of vulnerability and suggest directions for targeting alcohol preventive interventions. IMPLICATIONS AND CONTRIBUTION: After high school, young Black men are exposed to racial discrimination that can increase rates of binge drinking. When young men's parents were emotionally and instrumentally supportive toward them, however, racial discrimination did not predict increases in binge drinking.

Men's emerging adult romantic relationships forecast downstream relationship behavior, including commitment and quality. Accumulating evidence implicates methylation of the oxytocin-receptor-gene (OXTR) system in regulating relationship behavior. We tested hypotheses regarding the links between (a) childhood adversity and (b) socioeconomic instability in emerging adulthood on supportive romantic relationships via their associations with OXTR methylation. Hypotheses were tested using path analysis with data from 309 participants in the African American Men's Project. Consistent with our hypotheses, results showed that OXTR methylation proximally predicted changes in relationship support during a 1.5-year period. Childhood adversity was not directly associated with OXTR methylation but, rather, with contemporaneous socioeconomic instability, which in turn predicted elevated OXTR methylation. Findings suggest that early adversity is indirectly associated with OXTR methylation by links with downstream socioeconomic instability. Findings must be considered provisional, however, because preregistered replications are needed to establish more firmly the relations among these variables.

Informed by ecological and family system frameworks, our study investigated the relationship between family- and community-level factors, and their cross-level interactions, with evidence-based home visiting program participation in a sample of 2409 mothers (mean age: 24.15 years). Using 2-level hierarchical linear modeling, we observed that mothers living in disadvantaged communities demonstrated less active engagement in evidence-based home visiting. Cross-level interaction effects revealed that mothers' unstable living conditions and psychiatric problems amplified the negative influence of disadvantaged communities on program engagement. Conversely, mothers who were first-time parents showed higher levels of participation in family support programs when they resided in disadvantaged communities.

This study examined lower life satisfaction, active coping and cardiovascular disease risk factors (diastolic and systolic blood pressure, body mass index, and circumferences) in older African Americans over the phases of an 18-month church-based intervention, using a quasi-experimental design. Participants (n = 89) were 45 years of age and older from six churches (three treatment, three comparison) in North Florida. Lower life satisfaction had a persistent unfavorable effect on weight variables. Active coping showed a direct beneficial effect on selected weight variables. However, active coping was adversely associated with blood pressure, and did not moderate the association between lower life satisfaction and cardiovascular risk factors. The intervention had a beneficial moderating influence on the association between lower life satisfaction and weight variables and on the association between active coping and these variables. Yet, this pattern did not hold for the association between active coping and blood pressure. The relationship of lower life satisfaction and selected cardiovascular risk factors and the positive effect of active coping were established, but findings regarding blood pressure suggest further study is needed.

While studies have shown that maternal mortality rates have been improving worldwide, rates are still high across developing nations. In general, poor health of women is associated with higher maternal mortality rates in developing countries. Understanding country-level risk factors can inform intervention and prevention efforts that could bring high maternal mortality rates down. Specifically, the authors were interested in investigating whether: (1) secondary education participation (SEP) or age at marriage (AM) of women were related to maternal mortality rates, and (2) adolescent birth rate and contraceptive use (CU) acted as mediators of this association. The authors add to the literature with this current article by showing the relation of SEP and AM to maternal mortality rates globally (both directly and indirectly through mediators) and then by comparing differences between developed and developing/least developed countries. Path analysis was used to test the hypothesized model using country level longitudinal data from 2000 to 2010 obtained from United Nations publications, World Health Organization materials, and World Bank development reports. Findings include a significant correlation between SEP and AM for developing countries; for developed countries the relation was not significant. As well, SEP in developing countries was associated with increased CU. Women in developing countries who finish school before marriage may have important social capital gains.

Previous studies have documented that early stressful family relationships influence subsequent stressful life circumstances and health outcomes over the life course. Less is known, however, about whether stressful parent-child relationships increase the influence of proximal stressors on youth health operating as a stress-sensitizing life context, and individual genetic variations have effects on these developmental processes. Informed by life course stress process theory, which focuses on the proliferation, accumulation, and interactions of stressors over the life course as health risks, we examined whether (a) parent-child disconnection influences the occurrence of stressful life events in young adulthood, (b) parent-child disconnection potentiates the impact of stressful life events on young adults' health, or (c) potential health impact is intensified further by individual genotype. Using longitudinal data from a nationally representative sample of 11,290 adolescents (Mean age 15.5 years, 53% female) over a period of 13 years, we found parent-child disconnection influenced young adults' stressful life events and amplified the impact of stressful life events on cardio-metabolic disease risk. We also found the association between stressful life events and cardio-metabolic disease risk was further intensified by the 5-HTTLPR polymorphism. Our findings demonstrate that stressful family relationships not only initiate stress processes over the early life course, but also sensitize youth to stressors, and that 5-HTTLPR polymorphism interacts with stressful life experiences to predict heightened disease risk.

Previous studies have documented that early adversity increases young adults' risk for diabetes resulting in morbidity and comorbidity with adverse health conditions. However, less is known about how inter-related physiological (e.g., body mass index [BMI]), psychological (e.g., depressive symptoms), and behavioral mechanisms (e.g., unhealthy eating and sedentary behavior) link early adversity to young adults' diabetes outcomes, although these mechanisms appear to stem from early stressful experiences. The current study tested the patterning of these longitudinal pathways leading to young adults' diabetes using a nationally representative sample of 13,286 adolescents (54% female) over a period of 13 years. The findings indicated that early adversity contributed to elevated BMI, depressive symptoms, and stress-related health behaviors. The impact of these linking mechanisms on hierarchical diabetes outcomes (i.e., prediabetes and diabetes) remained significant after taking their associations with each other into account, showing that these mechanisms operate concurrently. The findings emphasize the importance of early detection for risk factors of young adults' diabetes in order to minimize their detrimental health effects.

The present study investigated the mediating effects of adolescent BMI trajectories on socioeconomic continuity over the early life course using a nationally representative sample of 11,075 respondents. This study considered both the initial severity as well as change over time in BMI as psycho-physiological mediators. Consistent with the life course pathway model and the cumulative advantage and disadvantage principle, the results suggested that early socioeconomic adversity is associated with youth BMI trajectories over time, which in turn, impair young adult socioeconomic attainment. The results also revealed important gender and racial/ethnic differences in the hypothesized associations. These findings elucidate how early adversity exerts an enduring long-term influence on social attainment in young adulthood. Further, the findings suggest that effective obesity intervention and prevention programs should focus not only on the severity of obesity but also on growth in BMI over the early years.

INTRODUCTION: Prospective associations of adolescent cannabis use with nicotine use persistence are not well characterized but are important for informing prevention and policy. This study examined the association of 4 types of cannabis product use with subsequent persistent nicotine product use among adolescents. METHODS: We used prospective data from an adolescent cohort (14-17 years) from Southern California surveyed at baseline and at approximately 6-month follow-up (2022-2023). We incorporated three mutually non-exclusive analytic samples comprised of individuals with baseline past 6-month use of: (1) any nicotine product (N=308 [mean[SD] age = 16.3[0.6] years]), (2) e-cigarettes (n = 276), and (3) any combustible tobacco product (n = 137). Baseline past 6-month cannabis smoking, vaping, edible use, cannabidiol [CBD] or hemp product use, and any cannabis product use (yes/no) were separately modeled as predictors of past 6-month persistent use of any nicotine products, e-cigarettes, and combustible tobacco at follow-up. RESULTS: Baseline use of any cannabis product was associated with increased odds of persistent use of e-cigarettes or any nicotine product (adjusted odds ratio[OR] range: 1.96-2.66). Cannabis smoking was positively associated with persistent any nicotine product use (adjusted OR=2.19, 95 % CI=1.20-4.02). Cannabis smoking, vaping, and edible use predicted persistent use of e-cigarettes (adjusted OR range: 2.22-2.79). Cannabis product use did not predict combustible tobacco use persistence. Associations of CBD/hemp product use with nicotine use persistence outcomes were all non-significant. CONCLUSIONS: Adolescents who use cannabis may be at elevated risk for persistent nicotine use.

The present study investigated a comprehensive model that integrates contributions of early socioeconomic adversity (ESA) and multiple polygenic scores (PGSs) through different mechanisms leading to diabetic risk in early adulthood. The study used prospective, longitudinal data from the National Longitudinal Study of Adolescent and Adult Health (Add Health) with a sample of 5,728 youth of European ancestry. The results showed that both ESA and PGSs were involved in different mechanisms. ESA contributed additively to educational failures, BMI, depressive symptoms, and diabetes risk over the life course (an additive process). Also, ESA launched a cascading process that connected these outcomes in a successively contingent manner. In addition to ESA, youths' multiple PGSs directly contributed to educational, psychological, and BMI outcomes. Multiple PGSs for education, BMI, and type 2 diabetes influenced not only youth outcomes that they were supposed to predict directly but also additional youth outcomes showing biological pleiotropy. The findings highlight the value of incorporating molecular genetic information into longitudinal developmental life course research and provide insight into malleable characteristics and appropriate timing for interventions addressing youth developmental and health outcomes.

RATIONALE: Laboratory research in adults indicates that alcohol-related subjective effects are enhanced under some social conditions. However, it is unknown whether this "social facilitation" of alcohol effects occurs in adolescents and is associated with alcohol use in the natural ecology. OBJECTIVES: We examined associations of social facilitation of alcohol-related subjective effects with subsequent alcohol use among a relatively high-risk group of adolescents who reported drinking alcohol both with friends and alone. METHODS: Los Angeles high school students from a prospective study (N = 142; 51% female; 10th graders) completed a baseline survey that assessed alcohol-related "positive" and "negative" subjective effects in two contexts: social (alcohol with friends) and solitary (alcohol alone); social facilitation was calculated as the difference between social and solitary. Students then completed five semi-annual surveys spanning 30 months (2014-2017) assessing 30-day alcohol use (days used, number of drinks, binge drinking). RESULTS: Greater social facilitation of positive effects was significantly associated with greater number of alcohol use days (RR [95% CI] = 1.48 [1.19, 1.82]; p < .001), greater number of drinks (RR [95% CI] = 1.38 [1.14, 1.66]; p = .001), and greater odds of binge drinking (OR [95% CI] = 1.75 [1.20, 2.57]; p = .004). Similar associations were found with social positive effects. There were no significant associations between solitary positive effects-or any negative effects-and alcohol use outcomes. CONCLUSIONS: Social facilitation can be measured outside of the laboratory. Relatively high-risk drinking adolescents who are more susceptible to the social facilitation of subjective alcohol effects are more likely to use more alcohol and binge drink.

The development of supportive and committed romantic relationships during emerging adulthood forecasts relationship quality later in adulthood. Many emerging adult African American men are exposed to challenging socioeconomic environments that are known to undermine romantic relationships. Studies of African American men's romantic relationship quality and its antecedents during this developmental period are scarce. The present study investigates longitudinal trajectories of romantic relationship quality among African American emerging adult men and then tests a model linking them to adverse childhood experiences, socioeconomic instability, community disadvantage, and defensive relational schemas. The analytic sample included 331 African American men who reported having a romantic partner, observed during three waves of data collection from ages 19 to age 26. Using men's reports of romantic relationship support, conflict, and dyadic trust, parallel growth mixture modeling was conducted to identify romantic relationship trajectory profiles. We identified three romantic relationship trajectory profiles: Normative, Uncertain, and Conflictual. Structural equation analyses revealed that adverse childhood experiences were associated positively with contemporaneous contextual risk factors (i.e., socioeconomic instability and community disadvantage), which in turn, were associated significantly with membership in Uncertain and Conflictual trajectories through defensive relational schemas. The present study reveals heterogeneous romantic relationships among African American emerging adult men. Findings support the conjoint influences of early adversity and contemporaneous stressors as robust antecedents of African American men's romantic relationship behaviors over time.

Cannabis legalization and commercialization has resulted in novel alternative cannabis products on the market, including edible and vaporized cannabis, which may appeal to youth with psychiatric problems. Psychiatric comorbidity in adolescent use and poly-use (i.e., use of >2 products) of combustible, edible, and vaporized cannabis products has largely gone uninvestigated. This 2015 cross-sectional survey of Los Angeles, California area adolescents (Mage = 16.1, N = 3177) characterized associations of various psychiatric problems with use and poly-use of combustible, edible, and vaporized cannabis. Exposure variables included past 30-day non-cannabis substance use (alcohol, e-cigarettes, combustible cigarettes, and nonmedical prescription opioid and stimulant use; yes/no), and psychiatric problems including past-week depressive symptom frequency, past 6-month ADHD symptom and conduct problem frequency, anhedonia, and five dimensions of impulsivity (sensation seeking, perseverance, lack of premeditation, positive urgency, and negative urgency). Outcome variables included past 30-day use (yes/no) of combustible, edible, and vaporized cannabis, independently, and number of cannabis products used (single, dual-use, poly-use). Results showed that all forms of non-cannabis substance use (ORs range: 13.7-36.1) and all psychiatric symptoms and traits (ORs in SD units range: 1.1-2.1) were positively associated with combustible, edible, and vaporized cannabis product use. The magnitude of comorbidity did not significantly differ by cannabis product type used in most cases. Psychiatric comorbidity was typically stronger in poly-product than single-product cannabis use and greater for externalizing-type than internalizing-type psychiatric problems. Practitioners, policy makers, and scientists should be aware that pervasive psychiatric comorbidity may be observed across the spectrum of cannabis product use among adolescents, particularly poly-product users.

BACKGROUND AND AIMS: The construct of susceptibility to substance use initiation (i.e. cognitive proclivity to future use) is critical for prevention efforts in adolescent populations. This study aimed to provide empirical evidence for the validity of the susceptibility construct for different cannabis products (i.e. combustible, edible or vaporized cannabis), and evaluate whether susceptibility measures are predictive of subsequent initiation. DESIGN: Prospective cohort study including baseline data (Spring 2015) and four follow-up surveys administered every 6 months through Spring 2017. SETTING: Ten schools in the Los Angeles, California metropolitan area. PARTICIPANTS: Adolescents [n = 2100; mean age = 16.1; standard deviation (SD) = 0.41; 54% female] who reported never having used any cannabis product at baseline. MEASUREMENTS: We assessed five indices of a susceptibility to use cannabis composite index at baseline, adapted from a validated tobacco use index (intention to use, willingness, curiosity and positive/negative cannabis use outcome expectancies, with four response categories, definitely not [1] to definitely yes [4]), by cannabis product (combustible, edible or vaporized). A composite index was created for each product by averaging responses across the five susceptibility items. Subsequent initiation of use of each cannabis product was assessed at each follow-up wave. FINDINGS: Factorial validity for unidimensionality for each five-item index (by product) was confirmed. The composite index for susceptibility to cannabis use was greatest for combustible (mean = 1.44; SD = 0.58), moderate for edible (mean = 1.37; SD = 0.53) and lowest for vaporized cannabis (mean = 1.30; SD = 0.44). The associations of each composite susceptibility index with subsequent initiation of that product and each of the other cannabis products over follow-up (i.e. cross-product associations) were statistically significant, with hazard ratios ranging from 2.30 to 2.80 across 24 months of follow-up (all Ps < 0.05). CONCLUSIONS: A five-item susceptibility to cannabis use composite index (by product) appears to be useful for characterizing and predicting youth at risk for cannabis use initiation across a spectrum of cannabis products.

BACKGROUND: Data from controlled laboratory experiments in adults indicate that the subjective effects of cannabis vary by administration method (e.g., combustible, vaporized). Whether the subjective effects of cannabis experienced in the natural ecology and among adolescents differ by cannabis administration method is unknown. In this observational study, adolescents' retrospective reports of subjective effects after combustible, edible, and vaporized cannabis use were examined. METHODS: Students from ten public schools in Los Angeles, CA, USA (M[SD] ageâ¯=â¯16.1 [.43] years) who reported past 6-month use of combustible, edible, or vaporized cannabis (N = 584) were surveyed on subjective effects experienced after use (yes/no). They were provided with a 12 item self-report checklist of six positive (e.g., relaxed, energetic) and six negative (e.g., drowsy, lazy) subjective effects. For each method of administration, affirmative responses were summed in positive (range: 0-6) and negative (range: 0-6) effect composite scores. RESULTS: Generalized estimating equations adjusted for demographics and recent cannabis use revealed a graded pattern of differences in positive subjective effects across products, with highest scores for combustible (M[SD]â¯=â¯3.98[1.76]), followed by edible (M[SD]â¯=â¯3.58 [2.04]) and vaporized (M[SD]â¯=â¯3.11 [2.21]) cannabis (all pairwise cross-product contrasts pâ¯<â¯.01). Mean negative effect score was highest for edible (M[SD]â¯=â¯2.27 [1.95]), followed by combustible (M[SD]â¯=â¯1.94 [1.66]), and vaporized (M[SD]â¯=â¯1.34 [1.73]) cannabis, respectively (all pairwise contrasts pâ¯<â¯.02). CONCLUSION: Adolescents' reports of subjective effects varied across cannabis administration methods. Combustible cannabis' more desirable subjective effects profile might be indicative of higher abuse liability.

Although studies on romantic relationships are abundant, cumulative experiences in intimate relationship dissolution (i.e., dissolution of cohabitation and marriage) during young adulthood is not yet completely understood. Using a nationally representative sample of 9,275 young adults, we investigated heterogeneity in timing and frequency of relationship dissolution during young adulthood, as well as its developmental precursors to dissolution. Results indicated four distinct relationship-dissolution classes that ranged from those who maintained stable romantic relationships to those who experienced multiple cohabitation dissolutions and divorces from ages 18 to 30 years. Early socioeconomic adversity predicted relationship-dissolution trajectories directly and indirectly through psychosociodemographic mechanisms in adolescence, including disrupted transitions to adulthood, conflict in dating relationships, and low levels of future orientation. Our findings highlight the heterogeneous romantic relationship trajectories of young adults and support the importance of the person-centered approach in elucidating developmental pathways underlying the longitudinal transitions in romantic relationships.

OBJECTIVE: The efficacy of the Strong African American Families (SAAF) alcohol use prevention program was tested. SAAF is a 7-session family skills training program offered in community settings. To overcome limitations of a past trial that used intent-to-treat (ITT) analyses, a Complier Average Causal Effect (CACE) analysis was used to estimate intervention effects and to determine the precise dosage of the intervention needed to achieve alcohol deterrence. METHOD: A sample of 472 African American youth and their caregivers were recruited randomly from public schools in 7 rural Georgia counties. Families were assigned randomly to receive SAAF or a no-treatment control. Youth provided data on their alcohol use during the past 3 months at 4 home visits, the final occurring 34 months after baseline and 28 months after the intervention. RESULTS: Efficacy was tested with Poisson latent growth curve models. SAAF deterred growth in alcohol use in models using both ITT and CACE estimation. CACE analyses revealed that, among participants who received a full dose of the intervention (7 sessions), a large treatment effect on slowed growth in alcohol use emerged (ß = -.83, p < .001). Dose-response analyses in CACE models revealed a medium-sized effect (d [95% CI] = 1.51 [1.25, 1.75]) when participants attended at least 5 of the 7 sessions offered. CONCLUSIONS: Replication of SAAF in a second randomized prevention trial supports the robustness of program effects. It is critical, however, that participant engagement protocols be designed to encourage participation in as at least 5 of the 7 sessions. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

OBJECTIVES: The current study, using prospective data over 25 years (1991-2015), concurrently investigates patterns of body mass index (BMI) and affective symptom trajectories in middle-aged mothers and the socioeconomic antecedents and disease outcomes of these patterns. METHOD: Growth mixture modeling was used to identify latent classes of conjoint health risk trajectories (BMI, depressive symptoms, and anxiety symptoms) from 1991 to 2001. For each latent class, we identified mean trajectories of each health risk. Then, analyses were conducted identifying how these conjoint health risk classes were associated with respondents' socioeconomic background profiles in 1991 and subsequent chronic health problems in 2015. RESULTS: Socioeconomic background profiles were significantly associated with initially high-risk trajectories. There was a statistically significant association between membership in certain classes of conjoint trajectories and physical health outcomes in later years. Consistent patterns of association with changes in different health outcomes including onset of diseases were observed when classes of conjoint risk trajectories are examined. DISCUSSION: The identification of members of various conjoint risk trajectory groups provides a potentially useful prognostic tool for early preventive intervention efforts, treatment, and policy formation. Such interventions should promote and develop resiliency factors, thereby aiding in the redirection of middle-aged women's adverse risk trajectories.
