The peripheral epigenome predicts white matter volume contingent on developmental stage: An ECHO study.

Epigenetic processes, including DNA methylation, are emerging as key areas of interest for their potential roles as biomarkers and contributors to the risk of neurodevelopmental, psychiatric, and other brain-based disorders. Despite this growing focus, there remains a notable gap in our understanding of how DNA methylation correlates with individual variations in brain function and structure. Additionally, the dynamics of these relationships during developmental periods, which are critical windows during which many disorders first appear, are still largely unexplored. The current study extends the field by examining if peripheral DNA methylation of myelination-related genes predicts white matter volume in a healthy pediatric population [N = 250; females = 113; age range 2 months-14 years; Mage = 5.14, SDage = 3.60]. We assessed if DNA methylation of 17 myelin-related genes predict white matter volume and if age moderates these relationships. Results highlight low variability in myelin-related epigenetic variance at birth, which rapidly increases non-linearly with age, and that DNA methylation, measured at both the level of a CpG site or gene, is highly predictive of white matter volume, in early childhood but not late childhood. These novel findings propel the field forward by establishing that DNA methylation of myelin-related genes from a peripheral tissue is a predictive marker of white matter volume in children and is influenced by developmental stage. The research underscores the significance of peripheral epigenetic patterns as a proxy for investigating the effects of environmental factors, behaviors, and disorders associated with white matter.

Parental perceptions of body weight and appetite in infants and toddlers with cystic fibrosis.

Nutritional status has clinical relevance and is a target of guidance to parents of children with cystic fibrosis (CF). Growth is routinely monitored in CF clinics but there is no standardized way of assessing appetitive behaviors or parents' perceptions of their children's appetite. Greater understanding of these factors could improve clinical guidance regarding parent feeding behaviors. We therefore aimed to assess parent perceptions of child weight, and parent reports of child appetite using the Baby Eating Behavior Questionnaire (BEBQ), in a sample of infants and toddlers with CF, compared with a community sample. We additionally assessed relationships of parent perceptions of child weight with parent feeding behaviors in the sample with CF. Anthropometric and questionnaire data were collected for 32 infants and toddlers with CF, as well as 193 infants and toddlers drawn from RESONANCE, a community cohort study. Parents perceived children with CF to be lower in weight than their actual weight, to a greater extent than was evident in the community sample. Parents who perceived their children with CF to be underweight vs. right weight reported greater slowness in eating on the BEBQ. Parents perceived children with CF to have greater slowness in eating and lower enjoyment of food, compared to parents of children in the community sample, independent of sample differences in child weight, age, and sex. Our results demonstrate the potential utility of the BEBQ in a clinical sample and suggest it may be helpful for clinicians to assess parents' perceptions of their child's weight and appetite to promote a fuller understanding of the child's nutritional status, facilitate appropriate feeding behaviors and alleviate unnecessary concerns.

Green Space and Internalizing or Externalizing Symptoms Among Children.

Importance: Evidence suggests that living near green space supports mental health, but studies examining the association of green space with early mental health symptoms among children are rare. Objective: To evaluate the association between residential green space and early internalizing (eg, anxiety and depression) and externalizing (eg, aggression and rule-breaking) symptoms. Design, Setting, and Participants: Data for this cohort study were drawn from the Environmental Influences on Child Health Outcomes cohort; analysis was conducted from July to October 2023. Children born between 2007 and 2013 with outcome data in early (aged 2-5 years) and/or middle (aged 6-11 years) childhood who resided in 41 states across the US, drawing from clinic, hospital, and community-based cohorts, were included. Cohort sites were eligible if they recruited general population participants and if at least 30 children had outcome and residential address data to measure green space exposure. Nine cohorts with 13 sites met these criteria. Children diagnosed with autism or developmental delay were excluded, and 1 child per family was included. Exposures: Green space exposure was measured using a biannual (ie, summer and winter) Normalized Difference Vegetation Index, a satellite image-based indicator of vegetation density assigned to monthly residential history from birth to outcome assessment. Main Outcome and Measures: Child internalizing and externalizing symptoms were assessed using the Child Behavior Checklist for Ages 1½ to 5 or 6 to 18. The association between green space and internalizing and externalizing symptoms was modeled with multivariable linear regression using generalized estimating equations, adjusting for birthing parent educational level, age at delivery, child sex, prematurity, and neighborhood socioeconomic vulnerability. Models were estimated separately for early and middle childhood samples. Results: Among 2103 children included, 1061 (50.5%) were male; 606 (29.1%) identified as Black, 1094 (52.5%) as White, 248 (11.9%) as multiple races, and 137 (6.6%) as other races. Outcomes were assessed at mean (SD) ages of 4.2 (0.6) years in 1469 children aged 2 to 5 years and 7.8 (1.6) years in 1173 children aged 6 to 11 years. Greater green space exposure was associated with fewer early childhood internalizing symptoms in fully adjusted models (b = -1.29; 95% CI, -1.62 to -0.97). No associations were observed between residential green space and internalizing or externalizing symptoms in middle childhood. Conclusions and Relevance: In this study of residential green space and children's mental health, the association of green space with fewer internalizing symptoms was observed only in early childhood, suggesting a sensitive period for nature exposure. Policies protecting and promoting access to green space may help alleviate early mental health risk.

The Sleep Environment, Napping, and Sleep Outcomes among Urban Children With and Without Asthma.

OBJECTIVES: Children with asthma living in U.S. urban neighborhoods experience increased risk for asthma morbidity and poor sleep outcomes. In addition to asthma, environmental factors (e.g. noise, uncomfortable temperature, light exposure) related to urban poverty may disturb children's sleep. This study examined the association between environmental factors and sleep outcomes among urban children with and without asthma, and whether napping underlies the environment-sleep link. Additionally, the study tested whether these associations differed by health status (i.e. asthma) or race/ethnicity. METHOD: Participants included urban children aged 7-9 years with (N = 251) and without (N = 130) asthma from Latino, Black, or non-Latino White (NLW) background. Caregivers reported sleep environmental factors and naps. Sleep duration, efficiency, and nightly awakenings were assessed via actigraphy. RESULTS: Regardless of health status, frequent exposure to noise and light was associated with poorer sleep outcomes only among Latino children. In the full sample with and without asthma, noise exposure during nighttime sleep was related to more frequent daytime naps, which were linked to shorter nighttime sleep duration. CONCLUSIONS: Exposure to noise and light may play a particularly influential role in shaping urban children's sleep outcomes. Racial/ethnic differences and the potential mediating role of napping in this environment-sleep association may inform tailored interventions.

Association of maternal education, neighborhood deprivation, and racial segregation with gestational age at birth by maternal race/ethnicity and United States Census region in the ECHO cohorts.

Background: In the United States, disparities in gestational age at birth by maternal race, ethnicity, and geography are theorized to be related, in part, to differences in individual- and neighborhood-level socioeconomic status (SES). Yet, few studies have examined their combined effects or whether associations vary by maternal race and ethnicity and United States Census region. Methods: We assembled data from 34 cohorts in the Environmental influences on Child Health Outcomes (ECHO) program representing 10,304 participants who delivered a liveborn, singleton infant from 2000 through 2019. We investigated the combined associations of maternal education level, neighborhood deprivation index (NDI), and Index of Concentration at the Extremes for racial residential segregation (ICERace) on gestational weeks at birth using linear regression and on gestational age at birth categories (preterm, early term, post-late term relative to full term) using multinomial logistic regression. Results: After adjustment for NDI and ICERace, gestational weeks at birth was significantly lower among those with a high school diploma or less (-0.31 weeks, 95% CI: -0.44, -0.18), and some college (-0.30 weeks, 95% CI: -0.42, -0.18) relative to a master's degree or higher. Those with a high school diploma or less also had an increased odds of preterm (aOR 1.59, 95% CI: 1.20, 2.10) and early term birth (aOR 1.26, 95% CI: 1.05, 1.51). In adjusted models, NDI quartile and ICERace quartile were not associated with gestational weeks at birth. However, higher NDI quartile (most deprived) associated with an increased odds of early term and late term birth, and lower ICERace quartile (least racially privileged) associated with a decreased odds of late or post-term birth. When stratifying by region, gestational weeks at birth was lower among those with a high school education or less and some college only among those living in the Northeast or Midwest. When stratifying by race and ethnicity, gestational weeks at birth was lower among those with a high school education or less only for the non-Hispanic White category. Conclusion: In this study, maternal education was consistently associated with shorter duration of pregnancy and increased odds of preterm birth, including in models adjusted for NDI and ICERace.

A Pilot Randomized Control Trial Demonstrating the Efficacy of the SIESTA Sleep Hygiene Intervention.

Shorter sleep duration can negatively impact children's daytime functioning and health. Latino children living near urban areas in the Mainland U.S. and Island Puerto Rico (PR) can be exposed to urban poverty and sociocultural stressors that challenge optimal sleep outcomes. Interventions to improve urban Latino children's sleep health should consider families' cultural background and environmental context to enhance acceptability and feasibility. This work describes our stepwise, multimethod approach to adapting a culturally and contextually tailored "School Intervention to Enhance Latino Students' Time Asleep (SIESTA)" for sixth- to eighth-grade Latino children residing in Greater Providence and San Juan and findings from a pilot randomized control trial (RCT) demonstrating SIESTA's efficacy. Results indicated high acceptability and greater improvement of sleep duration and behaviors in SIESTA versus control participants. The SIESTA shows potential to improve sleep outcomes in urban Latino middle schoolers. Results will inform a large-scale RCT to evaluate SIESTA's effectiveness and barriers to implementation.

Impact of Family, Neighborhood, and Schools on Behavioral Health Needs of Justice-Involved Latinx Adolescents.

Latinx adolescents are overrepresented in the justice system and have high untreated behavioral health needs. We examined the family as well as promotive and inhibitive environments (i.e., neighborhood and school) and their associations on behavioral health among 181 first-time justice-involved Latinx adolescents. Results showed that more optimal caregiver-adolescent attachment was associated with fewer behavioral health needs; more negative caregiver-adolescent communication with greater behavioral health needs. Increased neighborhood disadvantage and negative school interactions served as inhibitive environments and were associated with greater behavioral health needs. Moderation analyses indicated that negative communication was associated with greater behavioral health needs among dyads with large acculturation differences but not for dyads close in acculturation. Findings underscore the need to assess the family relationships and communication, promotive/inhibitive environments, and acculturation differences when determining how to meet behavioral health needs among justice-involved Latinx adolescents.

Family asthma management and physical activity among urban children.

INTRODUCTION: Urban, low-income, and Black and Latino children with asthma experience higher morbidity and poorer outcomes compared to their suburban, higher-income, and non-Latino White counterparts. This risk is further compounded by higher rates of co-occurring overweight or obesity. Physical activity contributes to both asthma and overweight/obesity status, however, little is known about factors that may promote/limit physical activity among youth from low-income, urban, and racial/ethnic backgrounds. This study evaluates associations between asthma management behaviors and physical activity among a sample of racially/ethnically diverse youth with asthma of both healthy weight and overweight/obesity status. METHOD: 147 children with asthma (Mage = 8.3; 50% overweight/obese status, 58% Hispanic/Latino, and 26% Black) and their families completed the Family Asthma Management System Scale (FAMSS; McQuaid et al., 2005) between 2013 and 2015. Physical activity was measured with waist-worn accelerometers. Differences in FAMSS scores by physical activity levels and associations between FAMSS scores and physical activity for the total sample and by race/ethnicity and weight status were evaluated. RESULTS: Children who met recommended physical activity guidelines had higher FAMSS "medication adherence", t(89) = -2.04, p < .05, and "collaboration with health care provider", t(89) = -2.09, p < .05. More optimal "environmental control" related to lower levels of physical activity (ß = -.21, p < .05) while more optimal "medication adherence" was associated with higher levels of physical activity (ß = .21, p < .05). Differences in these associations were identified by race/ethnicity, though not weight status. CONCLUSIONS: Asthma management behaviors were associated with physical activity, with notable differences by race/ethnicity. Tailored interventions simultaneously addressing multiple health behaviors may be warranted. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Associations between area-level arsenic exposure and adverse birth outcomes: An Echo-wide cohort analysis.

BACKGROUND: Drinking water is a common source of exposure to inorganic arsenic. In the US, the Safe Drinking Water Act (SDWA) was enacted to protect consumers from exposure to contaminants, including arsenic, in public water systems (PWS). The reproductive effects of preconception and prenatal arsenic exposure in regions with low to moderate arsenic concentrations are not well understood. OBJECTIVES: This study examined associations between preconception and prenatal exposure to arsenic violations in water, measured via residence in a county with an arsenic violation in a regulated PWS during pregnancy, and five birth outcomes: birth weight, gestational age at birth, preterm birth, small for gestational age (SGA), and large for gestational age (LGA). METHODS: Data for arsenic violations in PWS, defined as concentrations exceeding 10 parts per billion, were obtained from the Safe Drinking Water Information System. Participants of the Environmental influences on Child Health Outcomes Cohort Study were matched to arsenic violations by time and location based on residential history data. Multivariable, mixed effects regression models were used to assess the relationship between preconception and prenatal exposure to arsenic violations in drinking water and birth outcomes. RESULTS: Compared to unexposed infants, continuous exposure to arsenic from three months prior to conception through birth was associated with 88.8 g higher mean birth weight (95% CI: 8.2, 169.5), after adjusting for individual-level confounders. No statistically significant associations were observed between any preconception or prenatal violations exposure and gestational age at birth, preterm birth, SGA, or LGA. CONCLUSIONS: Our study did not identify associations between preconception and prenatal arsenic exposure, defined by drinking water exceedances, and adverse birth outcomes. Exposure to arsenic violations in drinking water was associated with higher birth weight. Future studies would benefit from more precise geodata of water system service areas, direct household drinking water measurements, and exposure biomarkers.

Design of a community-based, Hybrid Type II effectiveness-implementation asthma intervention study: The Rhode Island Asthma Integrated Response (RI-AIR) program.

BACKGROUND: Pediatric asthma is among the most common health conditions and disproportionately impacts Black and Latino children. Gaps in asthma care exist and may contribute to racial and ethnic inequities. The Rhode Island Asthma Integrated Response (RI-AIR) program was developed to address current limitations in care. The aims of the RI-AIR Hybrid Type II effectiveness-implementation trial were to: a) simultaneously evaluate the effectiveness of RI-AIR on individual-level and community-level outcomes; b) evaluate implementation strategies used to increase uptake of RI-AIR. In this manuscript, we outline the design and methods used to implement RI-AIR. METHODS: School-based areas (polygons) with the highest asthma-related urgent healthcare utilization in Greater Providence, R.I., were identified using geospatial mapping. Families with eligible children (2-12 years) living in one of the polygons received evidence-based school- and/or home-based asthma management interventions, based on asthma control level. School-based interventions included child and caregiver education programs and school staff trainings. Home-based interventions included individualized asthma education, home-environmental assessments, and strategies and supplies for trigger remediation. Implementation strategies included engaging school nurse teachers as champions, tailoring interventions to school preferences, and engaging families for input. RESULTS: A total of 6420 children were screened throughout the study period, 811 were identified as eligible, and 433 children were enrolled between November 2018 and December 2021. CONCLUSIONS: Effective implementation of pediatric asthma interventions is essential to decrease health inequities and improve asthma management. The RI-AIR study serves as an example of a multi-level intervention to improve outcomes and reduce disparities in pediatric chronic disease. CLINICAL TRIALS REGISTRATION NUMBER: NCT03583814.

The Environmental Influences on Child Health Outcomes (ECHO)-Wide Cohort.

The Environmental Influences on Child Health Outcomes (ECHO)-Wide Cohort Study (EWC), a collaborative research design comprising 69 cohorts in 31 consortia, was funded by the National Institutes of Health (NIH) in 2016 to improve children's health in the United States. The EWC harmonizes extant data and collects new data using a standardized protocol, the ECHO-Wide Cohort Data Collection Protocol (EWCP). EWCP visits occur at least once per life stage, but the frequency and timing of the visits vary across cohorts. As of March 4, 2022, the EWC cohorts contributed data from 60,553 children and consented 29,622 children for new EWCP data and biospecimen collection. The median (interquartile range) age of EWCP-enrolled children was 7.5 years (3.7-11.1). Surveys, interviews, standardized examinations, laboratory analyses, and medical record abstraction are used to obtain information in 5 main outcome areas: pre-, peri-, and postnatal outcomes; neurodevelopment; obesity; airways; and positive health. Exposures include factors at the level of place (e.g., air pollution, neighborhood socioeconomic status), family (e.g., parental mental health), and individuals (e.g., diet, genomics).

Asthma-related lung function and physical activity patterns among children living in urban neighborhoods.

OBJECTIVE: Black and Latino American children residing in urban environments are at increased risk for comorbid asthma and obesity. Physical activity (PA) is a modifiable behavior known to contribute to the asthma-obesity phenotype. While research has indicated links between optimal asthma status and high PA among children, little is documented about whether this group may display other asthma and PA patterns that warrant clinical attention and tailored interventions. METHODS: Children with persistent asthma (N = 97) ages 7-9 and their caregivers from urban neighborhoods completed daily measures of asthma status and moderate-to-vigorous physical activity (MVPA) and questionnaires about health and sociodemographic characteristics. Clinical asthma guidelines (e.g. FEV1 ≥ 80%) and sample means were used to categorize children into high or low lung function and MVPA patterns. Individual, family, and contextual differences across lung function and MVPA patterns were investigated. RESULTS: Twenty-nine percent of participants displayed optimal lung function and high MVPA. The remainder of the sample exhibited various less optimal patterns (e.g. poorer lung function and high MVPA). Caregivers of children displaying poorer lung function and high MVPA levels were more likely to report asthma related fears than caregivers of children with low MVPA levels regardless of lung function status. CONCLUSIONS: Asthma and PA interventions can be tailored to better address each child's unique clinical and behavioral patterns. An enhanced understanding of risk factors for suboptimal patterns of asthma status and PA may aid in multicomponent intervention efforts.

EARLY IDENTIFICATION OF SUICIDE RISK FACTORS AMONG JUSTICE-INVOLVED YOUTH.

Suicidal thoughts and behaviors among juvenile justice populations are elevated. However, the characteristics of justice-involved youth who consider and attempt suicide are not well understood. This study examined suicidal ideation and attempt with first-time, preadjudicated diverted youth, and the relationship with commonly associated risk factors. The sample included 135 youth (50% male, M age = 14.48) that provided complete responses to self-reported lifetime suicidal ideation and attempt items. Analyses examined relationships between suicidal ideation/attempt and mental health, child welfare involvement, delinquency, self-cutting, and substance use. First time, preadjudicated diverted youth reported high rates of lifetime suicidal ideation (27%) and attempt (17%). Suicidal ideation and attempt were associated with sexually minoritized status and self-cutting, while child welfare involvement was only associated with suicidal ideation. This high-risk population would benefit from refined suicide screening and prevention services not always available to justice-involved youth living in the community.

Trends in risk behaviors and sexually transmitted infections among youth presenting to a sexually transmitted infection clinic in the United States, 2013-2017.

Background: Sexually transmitted infections (STIs) are increasing among adolescents and young adults (AYA) across the United States. However, data are scarce on trends in condom use, number of partners, and other STI risk factors among AYA. The present study evaluated associations between sexual behaviors and STI diagnoses over time among AYA. Methods: We evaluated linked encounters of AYA aged 13-26 attending an urban Northeast public STI clinic from 2013-2017. Demographics, risk behaviors, self-reported past year and lifetime STI, and STI diagnosis during clinic encounter (positive test for urine, oral, or anal chlamydia; urine, oral, or anal gonorrhea; urine trichomonas; HIV; and syphilis) were extracted from electronic health records. We estimated prevalence and performed trend analyses of the repeated cross-sectional data. Cochran-Armitage and Kruskal-Wallis trend test were conducted for categorical and continuous variables, respectively. Results: Among 3822 encounters, clinical STIs demonstrated statistically significant increases including chlamydia (+9%, p = 0.001), gonorrhea (+5%, p = 0.008), and syphilis (+3%, p = 0.006) all of which significantly increased over time, as did any STI (+10%, p < 0.001). HIV and trichomonas rates remained low and unchanged. Self-reported STI increased as well, both past year (+9%) and lifetime (+14%). Greater proportions of AYA reported multiple partners (+9%, p < 0.001), and condomless oral (+12%, p = 0.001) and vaginal/anal (+7%, p = 0.001) sex. Conclusion: Among AYA presenting to a STI clinic, the proportion who engaged in condomless sex and had multiple partners increased over a 5 year period, which corresponded to increased STI prevalence during this period. Preventions efforts for AYA should continue to emphasize the importance of condoms and partner selection.

Experimental methods to study sleep disruption and immune balance in urban children with asthma.

Study Objectives: We describe research methods developed to examine effects of sleep disruption on changes in immune balance, lung function, and cognitive performance in a sample of urban, ethnically diverse children with persistent asthma. Two case examples (8- and 10-year-old males) are presented to highlight methods of the current study and illustrate effects of experimentally disrupted sleep on the immune balance profile (Th1/Th2 cytokines), key sleep variables from polysomnography data, and lung function in our sample. Methods: Children follow an individualized structured sleep schedule consistent with their habitual sleep need (≥9.5 hours' time in bed) for six days before a laboratory-based experimental sleep protocol. Children then spend two successive nights in the sleep lab monitored by polysomnography: a baseline night consisting of uninterrupted sleep, and a disruption night, during which they are awoken for 2 minutes between 20-minute intervals of uninterrupted sleep. Evening and morning blood draws bracket baseline and disruption nights for immune biomarker assessment. Results: A shift towards immune imbalance following the sleep disruption protocol was observed in these illustrative cases. Conclusions: Data from these case examples provide evidence that the experimental protocol caused disruptions in sleep as observed on polysomnography and had the hypothesized downstream effects on immune balance associated with clinical asthma control. Documenting the effects of sleep disruption on immune function in children with persistent asthma is a crucial step towards understanding associations between sleep, immune balance, and asthma outcomes and provides important information for developing novel interventions for youth with asthma and suboptimal sleep. Clinical Trials: Not applicable.

Physical Activity Among Urban Children with Asthma: Does Sleep Matter?

The present study examined associations between sleep and physical activity among a diverse sample of 97 urban children (ages 7-9) with persistent asthma. Differences in associations were evaluated by race/ethnicity and weight status. The extent to which sleep moderated the association between lung function and physical activity was also evaluated. Generalized linear models were utilized to examine associations. Findings indicated that, among the aggregate sample, more frequent nighttime awakenings were associated with less time spent engaging in moderate-to-vigorous physical activity (MVPA). Important differences in these associations were identified by both race/ethnicity and weight status. Better lung function was associated with, (a) higher levels of MVPA for children with better sleep efficiency and fewer nighttime awakenings, and (b) lower levels of MVPA for children with poorer sleep efficiency and more frequent nighttime awakenings. In short, sleep mattered with respect to children's physical activity levels in this sample.

Family asthma management in urban children and its association with sleep outcomes.

Asthma symptoms impact children's sleep quality. However, it is unclear how families' daily management of their child's asthma is associated with sleep quality. We examine associations between family asthma management components and sleep duration and quality for urban children (ages 7-9 years). Additionally, we examine these associations by racial/ethnic group. Data were collected as part of a longitudinal study that examined the co-occurrence of asthma, allergic rhinitis, sleep quality, and academic functioning for urban children diagnosed with persistent asthma (N = 196). A semi-structured interview assessed family asthma management practices. Sleep quality data were collected via actigraphy. Our visual depiction of sleep outcomes show that those with higher family asthma management ratings present with longer sleep duration and better sleep quality. Among specific family asthma management components, we found a significant association between children's adherence to asthma medications and number of nighttime awakenings. For non-Latino Black (NLB) children, we found a significant association between environmental control and sleep duration. For urban children with asthma, clinical strategies to enhance overall family asthma management have the potential to support improved sleep quality. Additionally, for NLB children, asthma management interventions that provide environmental control practices may increase sleep duration.

Association of pregnancy attitudes and intentions with sexual activity and psychiatric symptoms in justice-involved youth.

Context: With over one-third of detained girls experiencing teenage pregnancy, it is critical that the juvenile justice system better addresses the sexual and reproductive health (SRH) needs of youth. Although pregnancy attitudes and intentions (PAI) are associated with pregnancy outcomes among the general adolescent population, this relationship has not been examined among justice-involved youth. Methods: Participants were drawn from a longitudinal study characterizing trajectories of behavioral and reproductive health and recidivism among newly justice-involved youth in a Northeast family court. Baseline and four-month follow-up data from 288 justice-involved youth (JIY) were analyzed to characterize PAI; examine associations between pregnancy intentions and unprotected sexual activity (i.e., no hormonal, intrauterine, or barrier protection against pregnancy); and explore the relationship between pregnancy intentions and psychiatric symptoms. Results: At baseline, 39% of JIY youth were sexually active, 44% of these youth reported inconsistent condom use and 14% had not used birth control at last sexual intercourse. Nearly half of sexually active youth reported some intent around pregnancy and those with any pregnancy intentions were more likely to report depression, low self-esteem, substance use, and trauma history. Pregnancy intentions at baseline predicted higher rates of unprotected sexual activity at four months (OR: 16.9, CI = 2.48-115.7). Conclusions: This study highlights the importance of developing and implementing more comprehensive SRH assessments and brief interventions for youth entering the justice system.

Predictors of cannabis use among first-time justice-involved youth: A cohort study.

BACKGROUND: Justice-involved youth use cannabis at higher rates than their same-aged peers increasing likelihood of adverse behavioral health consequences and continued legal involvement. This study examined individual level predictors of early onset use cannabis use (<13 years of age) and cannabis use initiation in the 12 months following first court contact. METHODS: Participants were 391 first-time justice-involved youth (56.9 % male; Mage = 14.6 years; 32.1 % White, 11.1 % Black, 14.7 % Other/Multi-racial, 42.2 % Latinx) and an involved caregiver (87.2 % female; Mage = 41.0 years). Baseline assessments captured individual level factors; cannabis use was assessed every four months post-baseline for 12 months. Primary analyses involved multivariable modified Poisson regressions and survival analysis. RESULTS: In multivariable models, youth who reported lifetime cannabis use (n = 188, 48.1 %) were older, reported alcohol use and positive cannabis use expectancies. Greater self-control and self-concept were associated with lower likelihood of lifetime cannabis use. Youth who initiated cannabis during the 12-month follow-up (n = 30, 14.8 %) tended to be older, White/non-Latinx, and to report more psychiatric symptoms (posttraumatic stress, externalizing, internalizing, and affect dysregulation), delinquent behavior, lower levels of self-control, poorer self-concept, greater drug use intentions and positive cannabis expectancies. In the multivariable survival analysis, affect dysregulation, internalizing symptoms, and more positive cannabis expectancies remained independently and positively associated with cannabis initiation. CONCLUSIONS: There is a critical and unique window of opportunity to prevent cannabis use initiation among first-time justice-involved youth. Research is needed to determine whether brief interventions that aim to modify expectancies about cannabis use reduce rates of cannabis initiation in this underserved population.
