INTRODUCTION: Over the past two decades, the prevalence of psychological distress and mental disorders among adolescents has markedly increased. This coincides with the advent and rapid adoption of social media, resulting in a proliferation of research examining time spent on social media and its relationship with mental health. However, to date, findings have been inconclusive. The active/passive model of social media behavior theorizes that "pa…
Co-design of the ‘OurFutures Vaping’ programme
Effective preventive interventions are urgently needed to address e-cigarette use (‘vaping’) and related harms among young people. There is a strong evidence base supporting the delivery of substance use preventive interventions in the school setting, and eHealth interventions can overcome common implementation barriers. However, there is a dearth of effective school-based e-cigarette preventive interventions available. This study summarizes the …

A Longitudinal Assessment of the Impact of Biological Maturity and Menarche on Adolescents’ Organized Sport and Physical Activity Participation
INTRODUCTION: Processes accompanying growth and maturation are known to impact physical activity (PA) participation among adolescents. This study evaluated the longitudinal impact of these processes on organized sport participation and moderate-to-vigorous PA (MVPA) among male and female adolescents. METHODS: This study used secondary analysis of data from a longitudinal cohort of 6639 adolescents (Age = 12.92 ± 0.81 years; Males = 3302; Females …
Efficacy of an instant messaging-based life-skills training program to prevent behavioral risk factors among adolescents in Europe
One of the most significant risk factors for cancer and several other adverse health outcomes is nicotine and tobacco use. Life-skills training programs conducted within the school curriculum are effective in preventing substance use, including nicotine and tobacco use, however, large-scale implementation is hindered by time, organizational and financial constraints. Providing life-skills training programs via smartphones may be a more economical…
Process evaluation of the digital Health4Life intervention among a sample of disadvantaged adolescents and teachers
Disadvantaged adolescents, including those from lower socioeconomic status (SES) or geographically remote backgrounds, engage in higher rates of risk behaviours, including poor diet, alcohol and tobacco use. While digital interventions targeting lifestyle risk behaviours show potential, few studies have focused on their implementation and relevance for this population. This study conducted a process evaluation of ‘Health4Life’, a universal school…
A mixed-methods study among adolescents and teachers in Bogotá, Colombia
Early onset of alcohol consumption among Colombian adolescents highlights the need for effective and accessible preventive interventions. This project aimed to conduct formative work to inform the adaptation of an effective eHealth alcohol use prevention program originally developed in Australia, the OurFutures Alcohol Module, to the Bogotá context. Twenty-six adolescents and 10 teachers in Bogotá participated in the study. We used a mixed-method…
Accelerating implementation of adolescent digital health prevention programs
Background: Chronic disease risk factors are increasing amongst adolescents, globally. Digital health prevention programs, which provide education and information to reduce chronic disease risk factors need to be equitable and accessible for all. For their success, multiple highly engaged stakeholders should be involved in development and implementation. This study aimed to evaluate stakeholders' support for, and perspectives on potential public …

Exploring the association between adolescent‐perceived parental monitoring on dietary intake
Parenting practices such as parental monitoring are known to positively impact dietary behaviours in offspring. However, links between adolescent-perceived parental monitoring and dietary outcomes have rarely been examined and never in an Australian context. This study investigated whether adolescent-perceived parental monitoring is associated with more fruit and vegetable, and less sugar-sweetened beverages (SSB) and junk food consumption in Aus…
Adolescent Lifestyle Behaviour Modification and Mental Health
This study examines longitudinal behaviour change in six key lifestyle behaviours—sleep, physical activity (PA), sedentary recreational screen time, diet, alcohol use, and tobacco use—and associations with mental health in a large study of Australian adolescents. Change between baseline (M age = 12.7, N = 6,639) and 3-year follow up (M age = 15.7, N = 4445) was investigated. Generalised linear mixed effects regressions modelled associations betwe…
The Triple E project
The trial is registered at the Australian New Zealand Clinical Trials Registry (ACTRN12623000399695). Date registered: 19/04/2023
Adolescent behavioural intentions
Health4Life shows promise in influencing adolescent intentions across various MHBC areas, especially immediately after intervention. However, further investigation is needed to sustain these intention changes beyond short term to facilitate behaviour change
Peer-Related Correlates of e-Cigarette Use in Australian Adolescents
Background This study examined cross-sectional associations between e-cigarette use and (i) perceived peer use of e-cigarettes and (ii) bullying (perpetration and/or victimisation) in Australian adolescents. Methods Data were collected in 2022 as part of a cluster randomised controlled trial. Logistic regressions examined associations between e-cigarette use (ever use) and the perceived proportion of friends who use e-cigarettes, bullying victimi…

Acceptability and feasibility of Strong & Deadly Futures, a culturally-inclusive alcohol and drug prevention program for Aboriginal and/or Torres Strait Islander secondary students
Although there are effective alcohol and drug prevention programs available for Australian secondary schools, no effective culturally-inclusive programs exist for Aboriginal and/or Torres Strait Islander students. To address this gap, we developed the Strong & Deadly Futures program for young people aged 12–14 years. The web-based program was developed with Aboriginal, Torres Strait Islander and non-Indigenous staff and students at four secondary…
The directionality of anxiety and gaming disorder
Gaming activities among adolescents have increased during the COVID-19 pandemic, bringing with it a growing concern for the potential harms of excessive gaming and its risk factors. Anxiety is frequently linked with gaming disorder, but studies investigating this association were mostly cross-sectional in design. Longitudinal studies that explore risk factors associated with gaming disorder are sparse and the trajectories of gaming disorder remai…

Strong and Deadly Futures
School-based programs can effectively prevent substance use; however, systematic reviews and consultation with stakeholders identified a need for effective, culturally inclusive programs for Aboriginal and/or Torres Strait Islander (hereafter Aboriginal) youth. This paper describes the development of Strong & Deadly Futures , a six-lesson, curriculum-aligned wellbeing and substance use prevention program that was designed for, and with, the Abori…
Stigma, discrimination and crystal methamphetamine (‘ice’)
Stigma and discrimination surrounding crystal methamphetamine use was common in this sample of Australian residents, with public stigma more prevalent than self-stigma. This highlights a need for stigma reduction initiatives. Given higher levels of knowledge were associated with less stigmatising attitudes, public education campaigns providing accurate, evidence-based information about crystal methamphetamine along with guidelines and support for…
Clustering of Six Key Risk Behaviors for Chronic Disease among Adolescent Females
Chronic diseases are the leading cause of disability and mortality globally. In Australia, females are at heightened risk. This research explored the prevalence, patterns, and correlates of six key risk behaviors (physical inactivity, poor diet, recreational screen time, inadequate sleep, alcohol use, and smoking) among adolescent females and whether knowledge of health guidelines was associated with adherence. Adolescent females completed an ano…
Lifestyle risk indices in adolescence and their relationships to adolescent disease burden
This lifestyle risk factor index represents a useful summary metric in the context of adolescent health promotion and non-communicable disease prevention. Lifestyle risk factors were found to cluster in adolescence, supporting the implementation of multiple health behaviour change interventions
