Development and testing of the capacity of organisations for system practices scale.

Background: Systems change approaches are increasingly adopted in public health to address complex problems. It is important that measures of systems change be developed so that the effects of systems change on health outcomes can be evaluated. Organisational practices are potential levers for systems change.

Underreporting of implementation strategies and barriers in physical activity interventions for young people at risk of problematic substance use: a brief report.

Background: Several studies have assessed whether physical activity interventions can reduce substance use in young people at risk of problematic substance use. This report identifies and describes the reporting of implementation characteristics within published studies of physical activity interventions for young people at risk of problematic substance use and provides recommendations for future reporting.

Methods: Reported implementation strategies (including intervention manualization), barriers, implementation fidelity, and personnel acceptance were extracted from studies of physical activity interventions for young people aged 12-25 years at risk of problematic substance use that were included in a previous systematic review of intervention efficacy.

Government, governance, and place-based approaches: lessons from and for public policy.

Background: Place-based approaches are increasingly applied to address the determinants of health, many of which are complex problems, to ultimately improve population health outcomes. Through public policy, government actions can affect the effectiveness of place-based approaches by influencing the conceptualisation, development, implementation, governance, and/or evaluation of place-based approaches. Despite the important role of public policy, there has been limited examination of public policy related to place-based approaches.

Behaviour change techniques in physical activity-focused interventions for young people at risk of problematic substance use: A systematic review and meta-analysis.

Aim: This systematic review investigates behaviour change techniques in interventions promoting physical activity for young people aged 12-25 years at heightened risk of problematic substance use, and the effect of these techniques on physical activity participation and substance use outcomes.

Methods: Four databases (PsycINFO, CINAHL, SPORTDiscus and Medline) were searched between November 2020 and November 2022 for randomized and non-randomized controlled studies according to inclusion criteria. Meta-analyses were calculated using weighted, standardized averages of effect sizes (Hedges' g).

Scoping review of practice-focused resources to support the implementation of place-based approaches.

Issue Addressed: There is increasing interest across public health research, policy, and practice in place-based approaches to improve health outcomes. Practice-focused resources, such as grey literature, courses and websites, are utilised by practitioners to support the implementation of place-based approaches.

Methods: A detailed search of two search engines: Google and DuckDuckGo to identify free practice-focused resources was conducted.

The C-CAP Process: A Comprehensive Approach to Community Resource Mapping.

Introduction: Place-based systems change approaches are gaining popularity to address the complex problems associated with locational disadvantage. An important stage of place-based systems change involves understanding the context that surrounds (re)produces a target problem. Community resource mapping can be used to establish the context and identify the strengths of a community that might be leveraged through systems change efforts.

Associations between pre-COVID-19 physical activity profiles and mental wellbeing and quality of life during COVID-19 lockdown among adults.

The COVID-19 pandemic has been detrimental to the physical and mental health and wellbeing of people across the globe. Regular physical activity has consistently demonstrated an array of health benefits, but the impact of regular physical activity habits pre-pandemic on health and wellbeing during the pandemic is largely unknown. The purpose of this study was to identify distinct pre-COVID-19 lockdown physical activity profiles [i.

Within-Person Associations Between Physical and Social Contexts With Movement Behavior Compositions in Adolescents: An Ecological Momentary Assessment Study Using a Compositional Data Analysis Approach.

Background: External contexts, including the social and physical contexts, are independent predictors of momentary physical activity and sedentary behaviors. However, no studies to date have examined how external contexts are related to overall momentary movement behavior compositions using compositional data analysis. Therefore, this study aimed to determine differences in momentary movement behavior compositions between different social and physical contexts in adolescents.

A Brief, Daily, Online Mental Health and Well-being Intervention for University Staff During the COVID-19 Pandemic: Program Description and Outcomes Using a Mixed Methods Design.

Background: The unprecedented changes and isolation measures to contain COVID-19 have had multiple psychological and social impacts, with implications for professional and personal functioning. Evidence-informed interventions that can be rapidly implemented under pandemic conditions to support mental health during such times are urgently needed.

Objective: The aim of this study was to determine the acceptability and preliminary outcomes of a daily online mental health promotion program for tertiary education staff during the COVID-19 pandemic.

Single Session and Short-Term Exercise for Mental Health Promotion in Tertiary Students: A Scoping Review.

Exercise can improve mental health; however many tertiary students do not reach recommended levels of weekly engagement. Short-term exercise may be more achievable for tertiary students to engage in to promote mental health, particularly during times of high stress. The current scoping review aimed to provide an overview of controlled trials testing the effect of short-term (single bout and up to 3 weeks) exercise across mental health domains, both at rest and in response to an experimentally manipulated laboratory stress task, in tertiary students.

The Effect of Interventions That Target Multiple Modifiable Health Behaviors on Symptoms of Anxiety and Depression in Young People: A Meta-Analysis of Randomized Controlled Trials.

Purpose: This meta-analysis aimed to determine the effect of interventions targeting multiple modifiable health behaviors (i.e., physical activity/sedentary behaviors, nutrition/diet, sleep, substance use) on depression and anxiety in young people.

Domain specific association between physical activity and affect in adolescents' daily lives: an ecological momentary assessment study.

Objective: Little is known about the domain specific associations between moderate-to-vigorous physical activity (MVPA) and affect. This study aimed to determine whether the association between MVPA and affect differed by domain in adolescents.

Design: Overall, 119 adolescents (mean age = 14.

Young people's attitudes towards integrating physical activity as part of mental health treatment: A cross-sectional study in youth mental health services.

Introduction: Due to the significant burden associated with mental disorders that have their onset in youth, there is a critical need to improve treatments and treatment outcomes. Given the evidence for physical activity (PA) as an effective intervention for reducing depression and anxiety symptoms in young people, we examined young people's attitudes towards and acceptability of PA as part of mental health treatment, predictors of current engagement in PA and predictors of attitudes towards PA as a treatment option.

Methods: Participants in this cross-sectional study were 88 young people (15-25 years) who were engaged in treatment at youth mental health services in Melbourne, Australia.

Blending an implementation science framework with principles of proportionate universalism to support physical activity promotion in primary healthcare while addressing health inequities.

Globally, insufficient physical activity (PA) is one of the main risk factors for premature mortality. Although insufficient PA is prevalent in nearly every demographic, people with socio-economic disadvantage participate in lower levels of PA than those who are more affluent, and this contributes to widening health inequities. PA promotion interventions in primary healthcare are effective and cost effective, however they are not widely implemented in practice.

Contextual influences on the within-person association between physical activity and affect in adolescents: an ecological momentary assessment study.

There is limited research on how the context in which moderate-to-vigorous physical activity (MVPA) occurs influences the relationship between physical activity and affect. This study aimed to investigate how the social context and physical environment enhance the relationship between MVPA and affect in daily life. Overall, 119 adolescents (mean age = 14.

Poor reporting of physical activity and exercise interventions in youth mental health trials: A brief report.

Aim: To describe the quality and completeness of the description and reporting of physical activity and exercise interventions delivered to young people to promote mental health or treat mental illness.

Methods: We conducted a series of scoping reviews identifying 64 controlled trials of physical activity and exercise interventions delivered to young people. We extracted: intervention characteristics, personnel and delivery format, the intensity, duration, frequency and type of physical activity or exercise.

Trends and correlates of meeting 24-hour movement guidelines: a 15-year study among 167,577 Thai adults.

Background: Time spent in physical activity (PA), sedentary behaviour (SB), and sleep always takes up the whole day. New public health guidelines combining recommendations for PA, SB, and sleep have been issued in several countries. Thailand was the first country to release the 24-h guidelines for adults.

Correlates of walking among disadvantaged groups: A systematic review.

Socioeconomically disadvantaged groups are less likely to be physically active. Walking is important to public health, therefore understanding correlates of walking will inform the development of targeted interventions. The aim of this systematic review was to examine the correlates of walking among socioeconomically disadvantaged adults.

Exercise interventions for mental disorders in young people: a scoping review.

Aims: This scoping review determines the breadth and outcomes of controlled trials testing the effect of physical activity/exercise interventions across mental health outcomes in young people with a mental disorder.

Methods: The literature search was conducted using the open-access 'Evidence Finder', a comprehensive youth mental health-specific database that is systematically populated from MEDLINE, Embase, PsycINFO and Cochrane CENTRAL databases.

Results: Sixteen publications were identified after meeting the following eligibility criteria: (1) participants were young people (mean age 12-25.

Physical activity and exercise in youth mental health promotion: a scoping review.

Background/aim: This scoping review examined the breadth and outcomes of controlled trials testing the effect of physical activity and exercise interventions across all mental health outcomes for mental health promotion and indicated prevention studies in young people.

Methods: The literature search was conducted using 'Evidence Finder'.

Results: Thirty publications were included.

Standardised criteria for classifying the International Classification of Activities for Time-use Statistics (ICATUS) activity groups into sleep, sedentary behaviour, and physical activity.

Background: Globally, the International Classification of Activities for Time-Use Statistics (ICATUS) is one of the most widely used time-use classifications to identify time spent in various activities. Comprehensive 24-h activities that can be extracted from ICATUS provide possible implications for the use of time-use data in relation to activity-health associations; however, these activities are not classified in a way that makes such analysis feasible. This study, therefore, aimed to develop criteria for classifying ICATUS activities into sleep, sedentary behaviour (SB), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA), based on expert assessment.

Correlates of Physical Activity Among Disadvantaged Groups: A Systematic Review.

Context: Socioeconomically disadvantaged adults have lower engagement in leisure-time physical activity than those who are more affluent. Identification of correlates of physical activity can inform the design of effective interventions. The aim of this systematic review was to identify consistent correlates of unspecified physical activity and leisure-time physical activity among socioeconomically disadvantaged adults.

Factors associated with the institutionalization of a physical activity program in Australian elementary schools.

The health benefits of classroom-based physical activity programs may only be sustained if programs are continually implemented over time. Despite the importance of instituting physical activity programs to ensure their continued implementation, little is known about factors associated with institutionalization of programs at a school level. The purpose of this study is to examine how school context, principal characteristics, and program attributes are associated with the institutionalization of Bluearth Foundation's Active Schools program in Australian elementary schools.

Correlates of physical activity and sedentary behaviour in the Thai population: a systematic review.

Background: Given the importance of knowing the potential impediments and enablers for physical activity (PA) and sedentary behaviour (SB) in a specific population, the aim of this study was to systematically review and summarise evidence on individual, social, environmental, and policy correlates of PA and SB in the Thai population.

Methods: A systematic review of articles written in Thai and English was conducted. Studies that reported at least one correlate for PA and/or SB in a healthy Thai population were selected independently by two authors.
