Importance Depressive symptoms have increased among US adolescents since 2010. It remains unclear as to what extent this increase will persist into young adulthood, potentially turning the youth mental health crisis into a young adult mental health crisis. Objective To test the association between birth cohort and adolescent depressive symptoms at...

Background While accumulating research has tested the hypothesis that screen time causes psychiatric symptoms in children, less attention has been paid to the hypothesis that children with psychiatric symptoms change their patterns of screen time and digital media use. We aimed to test whether children with psychiatric symptoms subsequently change...

Objectives To assess (1) the prevalence of suicide ideation/behavior among adolescents with short sleep by race/ethnicity and (2) the association between sleep duration and suicidal ideation and behavior among American youth by race/ethnicity from 2007 to 2019. Methods Data were drawn from the Youth Risk Behavior Surveillance System (YRBSS). Logis...

Background: The prevalence of e-cigarette and vaping products has increased in the past decade, especially among adolescents. To provide data that will inform identification of youth at high risk, the goals of this study are to determine the social, educational, and psychological health outcomes associated with e-cigarette use distinct from combus...

Background: The use of electronic cigarettes (or "vaping") among adolescents remains a public health concern given exposure to harmful substances, plus potential association with cannabis and alcohol. Understanding vaping as it intersects with combustible cigarette use and other substance use can inform nicotine prevention efforts. Methods: Data we...

Background: Common adolescent psychiatric symptoms cluster into two dominant domains: internalizing and externalizing. Both domains are linked to self-esteem, which serves as a protective factor against a wide range of internalizing and externalizing problems. This study examined trends in US adolescents' self-esteem and externalizing symptoms, an...

Background: Transgender and nonbinary (TGNB) populations experience high rates of hazardous drinking (HD) and alcohol use disorder (AUD) as well as unique treatment barriers. This is due, in-part, to discrimination and stigma within and outside of the healthcare system. Cultural adaptation of clinical interventions can improve outcomes for margina...

Background: Simultaneous alcohol and marijuana (SAM) use is associated with adverse consequences for youth. While SAM use is overall declining among youth, prior studies indicate increasing marijuana use among US adolescents who ever used cigarettes, suggesting possible moderation of the alcohol-marijuana relationship by cigarette use. Methods:...

Background Nicotine vaping among U.S. adolescents has risen rapidly over the past decade, particularly for youth in grade 12. While previous studies examined the relationship between nicotine vaping and combustible cigarette use, less is known about the co-occurrence between vaping and other tobacco products. Methods Using Monitoring the Future gr...

Purpose Adolescent internalizing symptoms are increasing in the United States. Changes in parenting practices, including monitoring and communication, have been hypothesized to contribute to these increases. We aimed to estimate trends in parenting practices and understand whether shifts in such practices explain increases in internalizing symptoms...

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 socioecon...

Background: Understanding time trends in risk factors for substance use may contextualize and explain differing time trends in substance use. Methods: We examined data (N = 536,291; grades 8/10/12) from Monitoring the Future, years 1991-2019. Using Latent Profile Analyses, we identified six time use patterns: one for those working at a paid job and...

Introduction Adolescent time use in recent cohorts is distinguished by large-scale changes, including shifts in parental monitoring, supervision, and adolescent activity patterns, that together may provide a more complete perspective on changing patterns of mental health than can be captured by single risk factors. Methods To determine whether pat...

Purpose The severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) pandemic is associated with worsening mental health among young adults, but further research is necessary to quantify the associations with depression and anxiety. Methods Using Monitoring the Future data (N = 1244 young adults, modal age: 19, Fall 2020 supplement), we examin...

Aim: To quantify the trends in frequent and occasional cannabis vaping, demographic differences and concurrent nicotine and alcohol use. Design: Observational study. Survey-weighted multinomial logistic regression models assessed trends and disparities in past 30-day cannabis use. Trends were assessed overall and by sex, race/ethnicity, parental...

Objective Suicidal behavior and bullying victimization are important indicators of adolescent psychological distress, and are patterned by sex, race/ethnicity and sexual identity. This study aimed to estimate trends and disparities in these factors along key demographics. Method Youth Risk Behavior Survey data (2015-2019, N=44,066) were collected...

Over the past decade, US adolescents’ depressive symptoms have increased, and changing religious beliefs and service attendance may be contributing factors. We examined the contribution of religious factors to depressive symptoms among 417,540 US adolescents (grades: 8, 10, 12), years:1991–2019, in survey-weighted logistic regressions. Among adoles...

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 S...

Purpose To examine predictors of using substances to cope with the COVID-19 pandemic, including pandemic-related isolation, stress, economic hardship, demographics, and prepandemic substance use. Methods A U.S. national sample (N = 1,244) was followed from the 12th grade in Spring 2019 to Fall 2020 (M = 19.6 years) when young adults were asked abo...

PurposeWe aimed to estimate the structure of internalizing and externalizing symptoms and potential time dynamics in their association. This is understudied among adolescents, despite increasing internalizing and decreasing externalizing symptoms in recent years.Methods We analyzed data from US Monitoring the Future cross-sectional surveys (1991–20...

Importance Childhood adversity (CA) is a powerful determinant of long-term physical and mental health that is associated with elevated risk for chronic disease and psychopathology. However, the degree to which CA contributes to mortality as a preventable driver of ill-health and death is unknown. Objective To estimate the contribution of CA to hea...

Objective: Suicidal ideation and plans are increasing among US adolescents. Changing prevalence of online victimization is frequently hypothesized as an explanation for this increase. We tested trends in online and offline victimization and whether they contribute to recent trends in adolescent suicidal outcomes. Methods: Youth Risk Behavior Sur...

Purpose Depression is increasingly common among US adolescents; the extent to which social media exposure contributes to this increase remains controversial. Methods We used Monitoring the Future data from 8th and 10th grade students (n = 74,472), 2009–2017, to assess the relationship between daily social media use and depressive symptoms. Self-re...

Sexual minority adolescents have worse sleep health than their peers. Adolescents who identify as heterosexual and report prior same-sex sexual contact (termed ‘discordant heterosexuals’) have elevated health risks, but little is known about this group’s sleep health. This study examined 2015–2017 Youth Risk Behavior Survey data (n = 12,773 high sc...

Prior research has documented the ways in which financial hardships negatively impact health, particularly mental health. However, this association between financial hardships and mental health outcomes has rarely been examined in sexual minorities. The purpose of this study was to examine associations between financial hardships and mental health...

To the Editor Riehm et al¹ report an association between social media use and increased risk of internalizing and combined internalizing/externalizing problems 1 year later (between waves 2 and 3 of Population Assessment of Tobacco and Health study data), controlling for psychopathology and alcohol/marijuana use at wave 1. However, the analytic str...

Sex tourism affects the sexual health of tourists and locals with whom they interact. However, a few studies have examined whether sex tourism is a risk factor for the acquisition of HIV and other sexually transmitted infections among men who have sex with men, and no such studies have been conducted in Western Europe. Almost 28% of our respondents...

The current study sought to examine awareness of, willingness to use, and preferences for available and theoretical administration modalities for HIV pre-exposure prophylaxis (PrEP) and the association of anal sex roles with these concepts among a sample of men who have sex with men (MSM) in Paris, France. Broadcast advertisements were placed on a...

The purpose of this study was to examine associations between perceived neighborhood safety and mental health burdens among gay, bisexual, and other men who have sex with men (MSM) in Paris, France. Participants were recruited through a geosocial networking application (n = 580) and completed a web-based cross-sectional survey. Modified Poisson mod...

Rectal douching is a common but potentially risky practice among MSM; MSM who douche may be ideal candidates for rectal microbicides as HIV prevention. Herein we explored rectal douching and its association with condomless receptive anal intercourse (CRAI), group sex, rates of HIV and other STIs, and likelihood to use rectal microbicide gels. We re...

Purpose: To date, no studies utilizing global positioning system (GPS) technologies to measure mobility and environmental exposures have been conducted among a sample of transgender women despite the potential salient role neighborhood contexts may play in the health of this population. As such, the purpose of this study was to assess the acceptabi...

Recent studies have examined sleep health among men who have sex with men (MSM), but no studies have examined associations of neighborhood characteristics and sleep health among this population. The purpose of this study was to examine associations between perceived neighborhood safety and sleep health among a sample of MSM in Paris, France. We pla...
