Background and Aims: Increasing numbers of school‐based drug surveys are transitioning data collection to electronic tablets from paper‐and‐pencil, which may produce a survey mode effect and consequent discontinuity in time trends for population estimates of drug prevalence. This study tested whether (a) overall, self‐reported drug use prevalence is higher on electronic tablets versus paper‐and‐pencil surveys, (b) socio‐demographics moderate survey mode effects and (c) levels of missing data are lower for electronic tablet versus paper‐and‐pencil modes. Design A randomized controlled experiment. Setting: Results are nationally representative of students in the contiguous United States. Participants: A total of 41 866 8th, 10th and 12th grade students who participated in the 2019 Monitoring the Future school‐based survey administration. Intervention and comparator: Surveys were administered to students in a randomly selected half of schools with electronic tablets (intervention) and with paper‐and‐pencil format (comparator) for the other half. Measurements Primary outcome was the total number of positive drug use responses. Secondary outcomes were the percentage of respondents completing all drug questions, percentage of drug questions unanswered and mean number of missing drug items. Findings The relative risk (RR) for total number of positive drug use responses for electronic tablets versus paper‐and‐pencil surveys were small and their 95% confidence intervals (CI) included the value of one for reporting intervals of life‐time (RR = 1.03; 95% CI, 0.93–1.14), past 12 months (RR = 1.01; 95% CI, 0.91–1.11), past 30 days (RR = 1.05; 95% CI, 0.93–1.20) and for heavy use (RR = 1.10; 95% CI, 0.93–1.29). Multiplicative interaction tests indicated no moderation of these relative risks by race (white versus non‐white), population density, census region, public/private school, year of school participation, survey version or non‐complete drug responses. Levels of missing data were significantly lower for electronic tablets versus paper‐and‐pencil surveys. Conclusions: Adolescent drug prevalence estimates in the United States differed little across electronic tablet versus paper‐and‐pencil survey modes, and showed little to no effect modification by socio‐demographics. Levels of missing data were lower for electronic tablets. [ABSTRACT FROM AUTHOR]

Abstract: Aims: To conduct a systematic review and meta‐analysis of studies in order to estimate the effect of US medical marijuana laws (MMLs) on past‐month marijuana use prevalence among adolescents. Methods: A total of 2999 papers from 17 literature sources were screened systematically. Eleven studies, developed from four ongoing large national surveys, were meta‐analyzed. Estimates of MML effects on any past‐month marijuana use prevalence from included studies were obtained from comparisons of pre–post MML changes in MML states to changes in non‐MML states over comparable time‐periods. These estimates were standardized and entered into a meta‐analysis model with fixed‐effects for each study. Heterogeneity among the study estimates by national data survey was tested with an omnibus F‐test. Estimates of effects on additional marijuana outcomes, of MML provisions (e.g. dispensaries) and among demographic subgroups were abstracted and summarized. Key methodological and modeling characteristics were also described. Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines were followed. Results: None of the 11 studies found significant estimates of pre–post MML changes compared with contemporaneous changes in non‐MML states for marijuana use prevalence among adolescents. The meta‐analysis yielded a non‐significant pooled estimate (standardized mean difference) of −0.003 (95% confidence interval = −0.012, +0.007). Four studies compared MML with non‐MML states on pre‐MML differences and all found higher rates of past‐month marijuana use in MML states pre‐MML passage. Additional tests of specific MML provisions, of MML effects on additional marijuana outcomes and among subgroups generally yielded non‐significant results, although limited heterogeneity may warrant further study. Conclusions: Synthesis of the current evidence does not support the hypothesis that US medical marijuana laws (MMLs) until 2014 have led to increases in adolescent marijuana use prevalence. Limited heterogeneity exists among estimates of effects of MMLs on other patterns of marijuana use, of effects within particular population subgroups and of effects of specific MML provisions.

Aim The aim of this study was to explore what is known about food literacy programmes targeting adolescents, including identification of the constituents of food literacy addressed, assessment of programme effectiveness, and description of programme design or delivery specific to adolescents. Methods A review of the peer-reviewed literature surrounding adolescent food literacy was conducted using scholarly electronic databases. Programme reports were identified in the grey literature using online searching and cross-referencing to support the research aim. Programmes from 2000 to 2012 targeting adolescents aged 13-17 years were included. Results A total of 19 peer-reviewed papers and four grey literature programmes met the search criteria. Interventions focused on practical cooking and/or food preparation skills and targeted younger adolescent age groups. Programmes were most commonly held in schools and community settings. The majority of programmes (n = 16/23) did not use a theoretical basis for their development. Programme evaluation encompassed the use of pre- and post-intervention questionnaires and focus groups. Only nine studies included a dietary behaviour-based outcome measure. Although 19 of the 23 studies reviewed reported positive changes related to the intervention, these did not include significant changes in diet quality or cooking frequency at home. Conclusions Few existing adolescent food literacy programmes have demonstrated a positive impact on dietary behaviours to date. Adolescent target groups present unique challenges in programme development and delivery. However, the physical, social and emotional health needs of this age group and potential to influence lifelong behaviours highlight the need to design effective and age-appropriate adolescent food literacy programmes.

Objective: Assess the prevalence of headache in transgender and gender‐diverse adolescents, comparing prevalence with and without exposure to gender‐affirming hormone therapy. Background: Transgender and gender‐diverse youth are an understudied group in whom we can study the effects of sex steroids on adolescents' development of headache. We hypothesized that transfeminine adolescents treated with estrogen would have higher odds of headache than those not treated, and that transmasculine adolescents treated with testosterone would have lower odds of headache than those not treated. Methods: This retrospective case–control study analyzed all patients seen at the Boston Children's Hospital Gender Multispecialty Service clinic from 2007 to 2017. Cases were defined as patients with headache, controls as those without headache, and exposure as treatment with gender‐affirming hormone therapy (i.e., estrogen or testosterone). A computerized search identified cases that were then validated by chart review. Results: Fifty‐two of the 763 transgender and gender‐diverse patients seen were confirmed to have headache. Of 273 transfeminine patients 45% (123/273) received estrogen treatment. Transfeminine patients receiving estrogen were more likely to have headache than those not receiving estrogen (7% [9/123] vs. 1% [2/150]; odd ratio [OR] 5.84 (95% confidence interval [CI] 1.24–27.6), p = 0.026). Of 490 transmasculine patients, 46% (227/490) received testosterone. Transmasculine patients receiving testosterone were more likely to have headache than those not receiving testosterone (12% [28/227] vs. 5% (13/263); OR 2.71 (95% CI 1.37–5.4), p = 0.005). Conclusion: Among transfeminine and transmasculine youth, those who received gender‐affirming hormone therapy had higher odds of headache compared to those not taking gender‐affirming hormone therapy. Further prospective studies to guide headache care of transgender and gender‐diverse youth and adults are needed. Our results could be generalizable to other pediatric gender management clinics and may be worth discussing with patients considering treatment. [ABSTRACT FROM AUTHOR]

Objective: The COVID‐19 pandemic hastened a transition to treatment delivery via telehealth. While barriers still exist, the increased uptake of telehealth has the potential to increase access to mental health treatment for all diagnoses, including eating disorders. Delivery of evidence‐based treatment as well as adjunctive treatments, including those that are hard to find in‐person, have been modified to virtual format to increase accessibility and allow for continuity of care for adolescents with anorexia nervosa. Method: We describe how to modify and deliver Cognitive Remediation Therapy for youth with anorexia nervosa (CRT‐AN) via a telehealth platform. Preliminary and practical guidance for best practice for both group and individual delivery is established. Results: With minimal modifications, CRT‐AN can be delivered via telehealth for both individual and group delivery. More disengagement in group delivery was noted; however, overall application of the treatment via a remote platform was observed. Discussion: As more treatment moves to a telehealth format, highlighting how an adjunctive treatment like CRT‐AN can combined with other treatments in a telehealth format has the potential to increase research in its implementation and furthermore increase its dissemination. Public Significance: Cognitive Remediation Therapy for Anorexia Nervosa (CRT‐AN) requires significant manipulation of materials and supplementary human guidance. Suggestions for how to modify CRT‐AN for remote delivery via telehealth are provided. Modifications grew out of immediate changes made during the beginning of the COVID‐19 pandemic and can be used to inform changes therapists and programs can make to continue to or begin to use CRT‐AN in a remote fashion.

Background: Simultaneous use of alcohol and cannabis to enhance each other's effect can cause potential harm. Time trends are diverging in adolescent use of alcohol, which is declining, and cannabis, which is increasing among certain subgroups. However, little is known about trends in their simultaneous and non‐simultaneous use. Racial and socioeconomic disparities are emerging in cannabis use, which may portend consequences to public health. Methods: The 2000 to 2020 Monitoring the Future surveys included approximately 38,000 U.S. 12th‐grade students with information on simultaneous use and pertinent demographic factors. A 5‐level alcohol/cannabis measure included past‐year simultaneous use (i.e., alcohol and cannabis use at the same time), non‐simultaneous alcohol and cannabis use, alcohol‐use‐only, cannabis‐use‐only, and no use. Multinomial logistic regressions estimated associations (adjusted relative risk ratios; aRRR) with time period (2000 to 2004, 2005 to 2009, 2010 to 2014, 2015 to 2020). Models were adjusted and included interactions with sex, race/ethnicity, and parental education. Results: Between 2000 and 2020, simultaneous alcohol/cannabis use among 12th graders decreased from 24.4% to 18.7%. From 2015 to 2020 compared to 2000 to 2004, the odds of simultaneous use (adjusted relative risk ratio (aRRR) vs. no use = 0.57, 95% CI [0.50, 0.66]) and alcohol‐use‐only (aRRR = 0.55, 95% CI [0.49, 0.61]) decreased, while cannabis‐use‐only odds increased (aRRR = 2.59, 95% CI [1.87, 3.59]). Notably, the prevalence of cannabis‐use‐only more than doubled from 2011 to 2019. The odds of simultaneous use, alcohol‐use‐only, and non‐simultaneous use of alcohol and cannabis declined more rapidly among males than females, whereas the odds for cannabis‐use‐only increased faster for females than males. Increases in cannabis‐use‐only were faster for non‐white adolescents. Conclusion: Simultaneous use of alcohol and cannabis is declining among U.S. adolescents, but the decline is slower among females than males. Declines in simultaneous use are largely concomitant with historical declines in alcohol use, indicating that a continued focus on reducing alcohol use among adolescents and young adults has extended benefits to other adolescent substance use. However, cannabis use without any reported past‐year alcohol use more than doubled in the last decade, a concerning trend. [ABSTRACT FROM AUTHOR]

BACKGROUND Being bullied online is associated with being bullied in school. However, links between online bullying and violence‐related experiences are minimally understood. We evaluated potential disparities in these associations to illuminate opportunities to reduce school‐based violence. METHODS: We used five cohorts of Youth Risk Behavior Survey national cross‐sectional data (2011‐2019, Ntotal = 73 074). We used survey‐weighted logistic and multinomial models to examine links between online bullying and five school‐based violence‐related experiences: offline bullying, weapon carrying, avoiding school due to feeling unsafe, being threatened/injured with a weapon, and physical fighting. We examined interactions by sex, race/ethnicity, and sexual identity. RESULTS: Being bullied online was positively associated with all offline violence‐related behaviors. Groups with stronger associations between online bullying and physical fighting, including boys, adolescents whose sexual identity was gay/lesbian or unsure, and many adolescents of color (Black, Hispanic/Latino, and Asian/Pacific Islander adolescents), had stronger associations between online bullying and either weapon carrying or avoiding school. CONCLUSIONS: Online bullying is not an isolated harmful experience; many marginalized adolescents who experience online bullying are more likely to be targeted in school, feel unsafe, get in fights, and carry weapons. Reduction of online bullying should be prioritized as part of a comprehensive school‐based violence prevention strategy. [ABSTRACT FROM AUTHOR]

BACKGROUND: The Project Connect Health Systems Intervention (Project Connect) uses a systematic process of collecting community and healthcare infrastructure information to craft a referral guide highlighting local healthcare providers who provide high quality sexual and reproductive healthcare. Previous self-report data on healthcare usage indicated Project Connect was successful with sexually experienced female youth, where it increased rates of human immunodeficiency virus (HIV) and sexually transmitted disease (STD) testing and receipt of contraception. This adaption of Project Connect examined its effectiveness in a new context and via collection of clinic encounter-level data. METHODS: Project Connect was implemented in 3 high schools. (only 2 schools remained open throughout the entire project period). Participant recruitment and data collection occurred in 5 of 8 participating health clinics. Students completed Youth Surveys (N=608) and a Clinic Survey (paired with medical data abstraction in 2 clinics [N=305]). RESULTS: Students were more likely than nonstudents to report having reached a clinic via Project Connect. Nearly 40% of students attended a Project Connect school, with 32.7% using Project Connect to reach the clinic. Students were most likely to have been referred by a school nurse or coach. CONCLUSIONS: Project Connect is a low-cost, sustainable structural intervention with multiple applications within schools, either as a standalone intervention or in combination with ongoing efforts.

ABSTRACT BACKGROUND Despite previous research indicating an adolescents' alcohol, tobacco, and other drug ( ATOD) use is dependent upon their sex and the sex composition of their social network, few social network studies consider sex differences and network sex composition as a determinant of adolescents' ATOD use behavior. METHODS This systematic literature review examining how social network analytic studies examine adolescent ATOD use behavior is guided by the following research questions: (1) How do studies conceptualize sex and network sex composition? (2) What types of network affiliations are employed to characterize adolescent networks? (3) What is the methodological quality of included studies? After searching several electronic databases ( PsycINFO, EBSCO, and Communication Abstract) and applying our inclusion/exclusion criteria, 48 studies were included in the review. RESULTS Overall, few studies considered sex composition of networks in which adolescents are embedded as a determinant that influences adolescent ATOD use. Although included studies all exhibited high methodological quality, the majority only used friendship networks to characterize adolescent social networks and subsequently failed to capture the influence of other network types, such as romantic networks. CONCLUSIONS School-based prevention programs could be strengthened by (1) selecting and targeting peer leaders based on sex, and (2) leveraging other types of social networks beyond simply friendships.

Summary: Objective: The objective of this study was to examine the relationship between diet and inflammation, and adiposity in minority youth. Design and Methods: The study was designed as a cross‐sectional analysis of 142 overweight (≥85th body mass index percentile) Hispanic and African–American adolescents (14–18 years) with the following measures: anthropometrics, adiposity via magnetic resonance imaging, dietary intake via 24‐h dietary recalls, and inflammation markers from fasting blood draws utilizing a multiplex panel. Partial correlations were estimated and analysis of covariance (ancova) models fit to examine the relationship among dietary variables, inflammation markers and adiposity measures with the following a priori covariates: Tanner stage, ethnicity, sex, total energy intake, total body fat and total lean mass. Results: Inference based on ancova models showed that the highest tertile of fibre intake (mean intake of 21.3 ± 6.1 g d−1) vs. the lowest tertile of fibre intake (mean intake of 7.4 ± 1.8 g d−1) was associated with 36% lower plasminogen activator inhibitor‐1 (P = 0.02) and 43% lower resistin (P = 0.02), independent of covariates. Similar results were seen for insoluble fibre. No other dietary variables included in this study were associated with inflammation markers. Conclusions: These results suggest that increases in dietary fibre could play an important role in lowering inflammation and therefore metabolic disease risk in high‐risk minority youth.

Background and purpose Our aim was to provide estimates of traumatic brain injury ( TBI) in 2050 for the African population by region, sex and age strata. Methods A literature search was performed in October 2014 in PubMed for population-based studies of TBI in different geographical locations. Articles were selected from Kenya (model 1), New Zealand (model 2) and the USA (model 3). In model 1, rates of road traffic injury in Kenya were used to estimate TBI rates in the African continent. Models 2 and 3 used existing TBI incidence estimates from other locations to estimate the burden of TBI for Africa in 2050. The 2050 African population, as projected by the United Nations, was used as a base population. Results Based on rates from model 1, the estimated total TBI count in Africa in 2050 is 5.98 ± 0.03 million, with the highest count in eastern (2.04 ± 0.01 million) and lowest count in southern (0.15 ± 0.00 million) Africa. A higher TBI count is predicted by models 2 (14.25 ± 0.75 million) and 3 (10.40 ± 0.02 million). Estimated TBI count is highest for males aged 15-34 (5.47 ± 0.55 million in model 2 and 3.21 ± 0.13 million in model 3). Conclusions Projected estimates of TBI in Africa are high, with a burden of anywhere between approximately 6 and 14 million new cases in 2050. This emphasizes the importance of developing accurate surveillance systems of TBI at a population level and public health measures to mitigate the risk and burden of TBI. [ABSTRACT FROM AUTHOR]

Aims To investigate whether the effects of family conflict on adolescent drinking differed as a function of 5-hydroxy tryptamine transporter-linked polymorphic region ( 5- HTTLPR) genotype cross-sectionally and prospectively in two independent samples of adolescents. Design Path analysis and multi-group analysis of two prospective datasets were conducted. Settings United States and United Kingdom. Participants Sample 1 was 175 adolescents in the United States (mean age = 15 at times 1 and 2 with a 6-month interval); Sample 2 was 4916 adolescents in the United Kingdon (mean age = 12 at time 1 and 15 at time 2). Measurements In both samples, demographics, tri-allelic 5- HTTLPR genotype and perceived family conflict were assessed at time 1. Alcohol use (frequency of drinking) and alcohol misuse (frequency of intoxication, frequency of drinking three or more drinks, maximum number of drinks) were assessed at times 1 and 2. Findings A significant gene-environment interaction on alcohol misuse at time 1 was found in both sample 1 (β = 0.57, P = 0.001) and sample 2 (β = 0.19, P = 0.01), indicating that the 5- HTTLPR low-activity allele carriers exposed to higher levels of family conflict were more likely to engage in alcohol misuse than non-carriers. A significant gene-environment interaction effect on change in alcohol misuse over time was found only in sample 1 (β = 0.48, P = 0.04) but not in sample 2. Conclusions Compared with non-carriers, adolescents carrying the 5- HTTLPR low-activity allele are more susceptible to the effects of family conflict on alcohol misuse. [ABSTRACT FROM AUTHOR]
