The inclusion of youth voices in research relating to their own daily environments, wellbeing, and development is increasingly recognized as essential to ensuring rigor and success in mobilizing community change. Few studies have qualitatively examined youths' experiences and perceptions in participatory roles. This paper presents insights and…

Background: ADHD often overlaps with pediatric asthma, leading to difficulties in treatment and management in clinical work. Previous research has explored their correlations but gained different conclusions. Thus, this work aims to fill this evidence gap. Methods: Initially, we conducted a cross-sectional study based on data from the National…

Objective: This study used a large U.S. population-based dataset to examine associations between childhood attention problems and adolescent substance use, sexual risk behavior, and delinquency. Methods: This prospective cohort study used data from the Future of Families and Child Wellbeing Study (n = 2,716). Bivariate statistics, multivariable…

Studies on how smoking media literacy (SML) is associated with susceptibility to smoking among adolescents in South Korea and Vietnam are scarce. Thus, we examined the association of SML with susceptibility to smoking among adolescents in these countries to initiate a collaborative global health program. In total, 460 adolescents (Vietnam: 277,…

This study investigated the extent to which adolescent social network positions are associated with the risk of lifetime daily smoking and nicotine dependence (ND), and whether these associations differ by gender. Using data from the National Longitudinal Study of Adolescent to Adult Health (N = 6,267), this study estimated multinomial logistic…

Polysubstance use is associated with myriad short- and long-term health outcomes. Although prior research has documented differences in polysubstance use between lesbian, gay, bisexual, transgender, queer/questioning, and other sexual and gender minoritized (LGBTQ +) youth and their heterosexual/cisgender counterparts, as well as between subgroups…

A later school start time policy has been recommended as a solution to adolescents' sleep deprivation. We estimated the impacts of later school start times on adolescents' sleep and substance use by leveraging a quasi-experiment in which school start time was delayed in some regions in South Korea. A later school start time policy was implemented…

Current use of vaping products has increased in recent years among youth in the United States. We conducted cross-sectional surveys of vaping product users aged 15-17 in New York in 2017 and 2019 to assess vaping frequency, reported nicotine content of vaping products used, risk perceptions of vaping and openness to vaping cannabis (2019 survey…

Background: Health policies are key social determinants of health, but may cause inequalities if their implementation does not match local needs and if resources are misallocated. This study tests the inverse prevention law on school tobacco policies, assessing inequity in their implementation and identifying contributing factors. Methods: A…

Tobacco surveillance in the United States is robust but cannot be quickly modified to capture newly identified tobacco products or behaviors. We present an example of a rapidly deployed nonprobability survey using social media recruitment that collected data on rapidly changing tobacco use behaviors. We recruited 15- to 17-year old current vapers…

This study investigated whether noticing cannabis education campaigns was associated with increased cannabis risk perceptions in Canada's three territories following non-medical cannabis legalization. Data were from the Cannabis Policy Study in the Territories, including 2452 participants, age [greater than or equal to]16 years residing in Yukon,…

Objective: Despite a nationwide ban on tobacco sales to people under 18 years of age, adolescents can still buy tobacco products in Amsterdam. This study aimed to understand the influence of the retail environment in adolescents' activity spaces on their tobacco-purchasing behaviour. Method: Interviews were conducted with 13 adolescents (aged…

Prevention of smoking uptake in young people is an essential public health target. We have previously reported a systematic review and meta-analysis of the effect of exposure to smoking imagery in films on the risk of smoking uptake in young people. This study updates that review, and includes studies of the effects of exposure to media vaping…

Diffusion of innovations theory can be used to understand how to prevent or slow the spread of harmful behaviors, such as e-cigarette use in adolescent social networks. This study explores how different network intervention strategies could impact diffusion dynamics through network simulations based on observed social norms and e-cigarette use…

School bullying and cyberbullying are serious public health problems that negatively affect the lives of school-aged children. We examined the correlation between risk behaviors and lack of resiliency factors with bullying and cyberbullying across seven Mediterranean countries. The sample consisted of 33,399 adolescents (51.1% girls) aged 11, 13,…
