Accelerating implementation of adolescent digital health prevention programs: analysis of insights from Australian stakeholders.

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 health impact of digital health prevention programs for adolescents and potential pathways for future implementation. Methods: Qualitative semi-structured online interviews with stakeholders. Stakeholder mapping identified key individuals, groups and organizations across Australia that may influence the implementation of digital health prevention programs for adolescents. Recorded and transcribed interviews were analyzed within the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) Framework, using deductive content analysis. Findings: Nineteen interviews were conducted in 2023 with stakeholders from government, health, non-government organizations, youth services, education, community settings and others. Four overarching themes were identified: (i) existing digital health initiatives are not fit for purpose; (ii) the co-creation of digital health prevention programs is critical for successful implementation; (iii) digital health prevention programs must address equity and the unique challenges raised by technology and; (iv) system level factors must be addressed. Interpretation: Stakeholders broadly supported digital health prevention programs, yet raised unique insights to ensure that future programs create public health impact by improving chronic disease risk factors among adolescents. These insights can be applied in future development of digital health prevention programs for adolescents to strengthen widespread implementation.

Service use and glycaemic control of young people with type 1 diabetes transitioning from paediatric to adult care: a 5-year study.

BACKGROUND: Regular contact with specialist care has been linked to better diabetes outcomes for young people with type 1 diabetes (YPwT1D), but evidence is limited to population-based service usage and outcomes. AIMS: This observational 5-year study sought to capture YPwT1D living in the study catchment area (covering metropolitan, regional and rural Australia) as they transitioned to adult-based diabetes healthcare services and to describe their glycaemic control and complication rates, service usage and associated factors. METHODS: Records between 2010 and 2014 in a public healthcare specialist diabetes database were extracted, care processes and outcomes were described, and associations were sought between episodes of care (EOC) and potentially predictive variables. RESULTS: Annual cohort numbers increased yearly, but without significant differences in demographic characteristics. Each year around 40% had no reported planned specialist care, and the average number of planned EOC decreased significantly year on year. Overall, mean HbA1c levels also reduced significantly, but with higher values recorded for those living in non-metropolitan than metropolitan areas (achieving significance in 3 out of 5 years). Diabetes complication assessments were only reported in 37-46%, indicating one in five with retinopathy and hypertension affecting one in three to five young people. CONCLUSIONS: Findings highlight the importance of investment to address the specific needs of adolescents and young adults and demonstrate the need for better support during these vulnerable early years, particularly for non-metropolitan residents. This will entail changes to funding mechanisms, the health workforce and infrastructure, and new models of care to provide equity of access and quality of specialist care.

Joint developmental trajectories of internalizing and externalizing problems from mid-childhood to late adolescence and childhood risk factors: Findings from a prospective pre-birth cohort.

There is limited evidence on heterogenous co-developmental trajectories of internalizing (INT) and externalizing (EXT) problems from childhood to adolescence and predictors of these joint trajectories. We utilized longitudinal data from Raine Study participants (n = 2393) to identify these joint trajectories from 5 to 17 years using parallel-process latent class growth analysis and analyze childhood individual and family risk factors predicting these joint trajectories using multinomial logistic regression. Five trajectory classes were identified: Low-problems (Low-INT/Low-EXT, 29%), Moderate Externalizing (Moderate-EXT/Low-INT, 26.5%), Primary Internalizing (Moderate High-INT/Low-EXT, 17.5%), Co-occurring (High-INT/High-EXT, 17%), High Co-occurring (Very High-EXT/High-INT, 10%). Children classified in Co-occurring and High Co-occurring trajectories (27% of the sample) exhibited clinically meaningful co-occurring problem behaviors and experienced more adverse childhood risk-factors than other three trajectories. Compared with Low-problems: parental marital problems, low family income, and absent father predicted Co-occurring and High Co-occurring trajectories; maternal mental health problems commonly predicted Primary Internalizing, Co-occurring, and High Co-occurring trajectories; male sex and parental tobacco-smoking uniquely predicted High Co-occurring membership; other substance smoking uniquely predicted Co-occurring membership; speech difficulty uniquely predicted Primary Internalizing membership; child's temper-tantrums predicted all four trajectories, with increased odds ratios for High Co-occurring (OR = 8.95) and Co-occurring (OR = 6.07). Finding two co-occurring trajectories emphasizes the importance of early childhood interventions addressing comorbidity.

Development and implementation of Australian State, territory, and national policy on the health and wellbeing of adolescents and young adults: An exploration of policy actor perspectives using the Consolidated Framework for Implementation Research.

OBJECTIVES: Government policies that support the health and wellbeing of young people (aged 10 to 25) can have important individual and societal impacts. The aim of this study was to explore policy actor perspectives on the development and implementation of Australian government policies focussed on the health and wellbeing of young people. METHODS: We utilised a qualitative research design consisting of semi-structured interviews with policy actors with experience working with Australian youth health policies. Our interview guide and analyses were informed by the Consolidated Framework for Implementation Research (CFIR). We interviewed 19 participants from various national, state, and territory bodies. RESULTS: Several specific barriers and facilitators to policy development and implementation were identified using the Consolidated Framework for Implementation Research. Key policy development barriers were limited available resources (e.g. staffing and funding) and low relative priority within health and political systems. Key policy implementation barriers were limited available resources, limited policy compatibility with health services, cosmopolitanism issues related to interagency collaboration, and a lack of policy evaluation. Meaningful engagement of young people could also be improved. CONCLUSIONS: Although Australian youth health policies are perceived as evidence-based and comprehensively developed, the ability to promote implementation remains stalled. IMPLICATIONS FOR PUBLIC HEALTH: The development of policy implementation plans, monitoring and evaluation mechanisms, funding and resources, and a strong commitment to removing barriers to working across multiple departments and systems is required to improve outcomes for young people.

Striking the right balance: co-designing the Health4Me healthy lifestyle digital health intervention with adolescents.

BACKGROUND: Adolescents are navigating a period of rapid growth and development within an era of digitalization. Mobile phone ownership among adolescents is nearly ubiquitous, and this provides an opportunity to harness text messaging to promote a healthy lifestyle and reduce chronic disease risk factors. Inclusion of adolescents throughout the design process has been recognized as essential for engagement and future implementation of such interventions. This study aimed to co-design a bank of text messages to promote a healthy lifestyle which are useful, acceptable, and engaging for adolescents aged 12-18 years old. METHODS: Iterative, mixed-methods design with consumer partnership. Co-design occurred over three stages: text message development, text message review and final refinement and testing. The text message development included literature searches and consumer partnership with an established youth advisory group (n = 16). Participants who gave e-consent participated in text message review. Demographic characteristics were collected, and quantitative surveys were distributed to adolescents (n = up to 50) and health professionals (n = up to 30), who rated text message content for understanding, usefulness and appropriateness (total score out of 15). Final refinement was completed by the research team to edit or remove messages which had low scores and to assess readability and interactivity of the text messages. RESULTS: The Heath Advisory Panel for Youth at the University of Sydney (HAPYUS) identified the top six lifestyle health issues for young people today in relation to chronic disease prevention, which became the key content areas for the text message bank and drafted new text messages. Following text message development, 218 messages were available for review. Adolescents (n = 18, mean age 16.3 [SD 1.4]) and healthcare professionals (n = 16) reviewed the text messages. On average, all reviewers found that the text messages were easy to understand (mean = 13.4/15) and useful (mean = 12.7/15). Based on scoring and open ended-feedback, 91 text messages were edited and 42 deleted. The final text message bank included 131 text messages. The overall program is suitable for a seventh-grade reading level, and interactive. CONCLUSIONS: This study describes the process of effectively engaging adolescents to co-design a text message bank intervention, which are useful, acceptable and engaging for an adolescent audience. The effectiveness of the co-designed text message bank is currently being tested in the Health4Me RCT.

Today's adolescents are growing and developing through a period of increased technology use. Most adolescents have access to a mobile phone which can be used to deliver healthy lifestyle information to them through text messages. However, it is important that researchers engage with adolescents as collaborators to develop any information which may be sent to them, to ensure that it is acceptable and engaging. We aimed to co-design a bank of text messages to promote a healthy lifestyle which are useful, acceptable and engaging for adolescents 12­18 years old. We engaged with 16 adolescents from an established youth advisory group who advised on top health issues they face today in terms of leading a healthy lifestyle, which became key content areas for the text message program. They also drafted text messages around these content areas (218 total). Next, the text messages underwent review with 34 adolescents and healthcare professionals to ensure they were useful, easy to understand and appropriate. After the review, the research team edited, deleted and replaced text messages which did not score well. This resulted in a text message bank to promote a healthy lifestyle with 131 text messages which were useful, acceptable and engaging for adolescents 12­18 years old.

A digital innovation typology: Navigating the complexity of emerging technologies to negotiate health systems research with young people.

Objective: This study aims to explore young people's perspectives of emerging technologies and health systems research in an adolescent health community of practice. Methods: The context of this integrated knowledge translation study is the Wellbeing Health & Youth Centre of Research Excellence in Adolescent Health. A theory-building, non-systematic review was conducted to examine the concepts and interrelationships of emerging technologies associated with digital innovation and health systems. This typology informed the design of an online workshop with young people to explore their views, concerns, and ideas about health systems research. Results: A digital innovation typology was identified to differentiate and explain emerging technology concepts and interrelationships that can be applied to the health systems context. Aligned with this typology, youth perspectives about digital health challenges and opportunities were identified to support future research, policy, and practice. Conclusion: The integrated findings from this study can assist the navigation of complex emerging technologies, and the negotiation of equitable health systems research, between youth and adult stakeholders. Further, with these typology-related resources, mutual learning and the public involvement of young people in health systems research and priority setting agendas can be supported.

Association of urinary sex hormones with mood and behavior changes in a community adolescent cohort.

OBJECTIVE: To examine the contribution of variation in sex hormone excretion to mood and behavioral changes in adolescent females and males. DESIGN: Prospective, longitudinal observational cohort study. METHODS: Participants were 342 volunteers aged 10-12 years living in rural Australia. Urinary estradiol and testosterone levels measured by liquid chromatography-mass spectrometry were obtained at three-month intervals for three years. Integrated measures (area-under-curve) of urinary steroid excretion summarised as absolute and variability during each 12-month period of the study. Psychosocial data were gathered annually with the primary outcome of depressive symptomatology. Secondary outcomes were the other subscales of the Youth Self-Report, impulsive-aggression, sleep habits, and self-harm. RESULTS: 277 (158 male) participants contributed data over the full duration of the study and could be included in the analyses. In females, analyses of absolute urine hormone levels found no relationship between estradiol and any outcome, but higher testosterone was significantly associated with depression and poorer sleep. Greater variability of both urine estradiol and testosterone was associated with lower total psychopathology, anxious/depressed and social problems scores. Greater variability in urine estradiol was associated with lower attention problems and impulsive aggression in females. In males, higher testosterone and estradiol levels were associated with rule-breaking, and poorer sleep, and no associations were found for gonadal hormone variability for males. CONCLUSIONS: Longitudinal measurement of both iso-sexual and contra-sexual gonadal hormones contributes to a more nuanced view of the impact of sex steroids on mood and behavior in adolescents. These findings may enlighten the understanding of the impact of sex steroids during normal male and female puberty with implications for hormone replacement therapies as well as management of common mood and behavioral problems.

Eating disorders in weight-related therapy (EDIT): Protocol for a systematic review with individual participant data meta-analysis of eating disorder risk in behavioural weight management.

The Eating Disorders In weight-related Therapy (EDIT) Collaboration brings together data from randomised controlled trials of behavioural weight management interventions to identify individual participant risk factors and intervention strategies that contribute to eating disorder risk. We present a protocol for a systematic review and individual participant data (IPD) meta-analysis which aims to identify participants at risk of developing eating disorders, or related symptoms, during or after weight management interventions conducted in adolescents or adults with overweight or obesity. We systematically searched four databases up to March 2022 and clinical trials registries to May 2022 to identify randomised controlled trials of weight management interventions conducted in adolescents or adults with overweight or obesity that measured eating disorder risk at pre- and post-intervention or follow-up. Authors from eligible trials have been invited to share their deidentified IPD. Two IPD meta-analyses will be conducted. The first IPD meta-analysis aims to examine participant level factors associated with a change in eating disorder scores during and following a weight management intervention. To do this we will examine baseline variables that predict change in eating disorder risk within intervention arms. The second IPD meta-analysis aims to assess whether there are participant level factors that predict whether participation in an intervention is more or less likely than no intervention to lead to a change in eating disorder risk. To do this, we will examine if there are differences in predictors of eating disorder risk between intervention and no-treatment control arms. The primary outcome will be a standardised mean difference in global eating disorder score from baseline to immediately post-intervention and at 6- and 12- months follow-up. Identifying participant level risk factors predicting eating disorder risk will inform screening and monitoring protocols to allow early identification and intervention for those at risk.

Psychosocial assessment of adolescents and young adults in paediatric hospital settings: patient and staff perspectives on implementation of the e-HEEADSSS.

BACKGROUND: The main causes of morbidity and mortality for adolescents and young adults are preventable and stem from psychosocial and behavioural concerns. Psychosocial assessments can help clinicians to identify and respond holistically to risks and strengths that may impact upon a young person's physical and mental health. Despite broad support at a policy level, the implementation of routine psychosocial screening for young people remains varied in Australian health settings. The current study focused on the pilot implementation of a digital patient-completed psychosocial assessment (the e-HEEADSSS) at the Sydney Children's Hospital Network. The aim of this research was to evaluate patient and staff barriers and facilitators to local implementation. METHODS: The research used a qualitative descriptive research design. Semi-structured interviews were conducted online with 8 young patients and 8 staff members who had completed or actioned an e-HEEADSSS assessment within the prior 5 weeks. Qualitative coding of interview transcripts was carried out in NVivo 12. The Consolidated Framework for Implementation Research guided the interview framework and qualitative analyses. RESULTS: Results demonstrated strong support for the e-HEEADSSS from patients and staff. Key reported facilitators included strong design and functionality, reduced time requirements, greater convenience, improved disclosure, adaptability across settings, greater perceived privacy, improved fidelity, and reduced stigma for young people. The key barriers were related to concerns over available resources, the sustainability and continuity of staff training, perceived availability of clinical pathways for follow-up and referrals, and risks related to off-site completions. Clinicians need to adequately explain the e-HEEADSSS assessment to patients, educate them about it, and make sure that they receive timely feedback on the results. Greater reassurance and education regarding the rigour of confidentiality and data handling procedures is required for patients and staff. CONCLUSIONS: Our findings indicate that continued work is required to support the integration and sustainability of digital psychosocial assessments for young people at the Sydney Children's Hospital Network. The e-HEEADSSS shows promise as an implementable intervention to achieve this goal. Further research is required to determine the scalability of this intervention across the broader health system.

Menstrual Dysfunction in Adolescents with Chronic Illness: A Systematic Review.

STUDY OBJECTIVE: Menstrual dysfunction can impact both the physical and emotional health of young people.1 Multiple chronic diseases have been associated with menstrual dysfunction in adults2; however, there is little research in adolescents, despite nonadherence and suboptimal illness control in this group. We aimed to identify the impact of chronic illness on the age of menarche and the menstrual cycle in adolescents. METHODS: Studies were extracted of female adolescents aged 10-19 who had a chronic physical illness. Data included outcomes on age of menarche and/or menstrual cycle quality. Exclusion criteria aimed to exclude diseases where menstrual dysfunction was a known part of the disease pathophysiology (ie, polycystic ovarian syndrome)3 or in which medications were used that directly impacted gonadal function.4 A literature search (to January 2022) was performed on the EMBASE, PubMed, and Cochrane library databases. Two widely used modified quality analysis tools were used. RESULTS: Our initial search netted 1451 articles, of which 95 full texts were examined and 43 met the inclusion criteria. Twenty-seven papers focused on type 1 diabetes (T1D), with 8 papers examining adolescents with cystic fibrosis and the remaining studying inflammatory bowel disease, juvenile idiopathic arthritis, coeliac disease, and chronic renal disease. Metanalysis of 933 patients with T1D vs 5244 controls demonstrated a significantly later age of menarche in T1D (by 0.42 years; P ≤ .00001). There was also a significant association between higher HbA1c and insulin dose (IU/kg) and later age of menarche. Eighteen papers reviewed other aspects of menstruation, including dysmenorrhea, oligomenorrhoea, amenorrhea, and ovulatory function, with variable findings. CONCLUSION: Most studies were small and in single populations. Despite this, there was evidence of delayed menarche and some evidence of irregular menses in those with cystic fibrosis and T1D. Further structured studies are needed to evaluate menstrual dysfunction in adolescents and how it relates to their chronic illness.

Eating Patterns of Young Women (18-25 y) with Overweight and Obesity: A Preliminary Investigation.

Overweight and obesity impact up to 40% of young women in Australia; however, young women are challenging to recruit to research and are rarely the focus of weight loss interventions. This study aimed to examine dietary patterns in young women (18-25 years; BMI > 25 kg/m2). An analysis of participants' (mean age: 22.6 year; BMI: 32.2 kg/m2) 3-day food records found young women with overweight/obesity consumed a diet characterised by total energy intake of 9174 (2526) kJ/day, with the first meal at 9:12 am (range: 4:30 am-12:40 pm), the last at 10:43 pm (range: 2:40 pm-2:00 am), and an average eating window of 11.5 h. Young women had poor quality diets, which did not meet dietary recommendations for most core food groups, and high intake of refined carbohydrates. They also reported consuming at least one takeaway meal per day and >30% of total energy intake was from discretionary items. The findings showed that young women with overweight or obesity consume most of their energy intake in the afternoons and late into the evenings and have poor-quality diets with high-discretionary intake, each of which have been shown in previous work to be associated with increased weight and risk of metabolic comorbidities. While these findings require further examination in larger groups with both qualitative and longitudinal data collection to verify the impact of these eating patterns on weight maintenance, the eating behaviours identified here may present a suitable target for novel weight loss interventions in young women, who are an understudied population group in need of tailored weight management solutions.

Eating Disorders In weight-related Therapy (EDIT) Collaboration: rationale and study design.

The cornerstone of obesity treatment is behavioural weight management, resulting in significant improvements in cardio-metabolic and psychosocial health. However, there is ongoing concern that dietary interventions used for weight management may precipitate the development of eating disorders. Systematic reviews demonstrate that, while for most participants medically supervised obesity treatment improves risk scores related to eating disorders, a subset of people who undergo obesity treatment may have poor outcomes for eating disorders. This review summarises the background and rationale for the formation of the Eating Disorders In weight-related Therapy (EDIT) Collaboration. The EDIT Collaboration will explore the complex risk factor interactions that precede changes to eating disorder risk following weight management. In this review, we also outline the programme of work and design of studies for the EDIT Collaboration, including expected knowledge gains. The EDIT studies explore risk factors and the interactions between them using individual-level data from international weight management trials. Combining all available data on eating disorder risk from weight management trials will allow sufficient sample size to interrogate our hypothesis: that individuals undertaking weight management interventions will vary in their eating disorder risk profile, on the basis of personal characteristics and intervention strategies available to them. The collaboration includes the integration of health consumers in project development and translation. An important knowledge gain from this project is a comprehensive understanding of the impact of weight management interventions on eating disorder risk.

Impact of growth, gonadal hormones, adiposity and the sodium-to-potassium ratio on longitudinal adolescent measures of blood pressure at puberty.

Blood pressure (BP) rises rapidly at puberty. While this is partly due to normal development, factors like excess adiposity and a high intake of dietary sodium relative to potassium may contribute to a true increase in hypertension risk. This study aimed to assess the relative impact of growth, gonadal hormones, adiposity and the sodium-to-potassium ratio (Na:K) on longitudinal BP measures at puberty. This study analysed data from a three-year longitudinal cohort study of pubertal adolescents. Anthropometry, body composition (bio-electrical impedance), serum testosterone and oestradiol (mass spectrometry) were measured annually. Na:K was measured from three-monthly urine samples. These variables were used to predict annual BP measures using mixed modelling and ordinal regression. Data from 325 adolescents (11.7 ± 1.0 y; 55% male) were analysed, showing typical growth patterns at puberty. Systolic BP increased over time in both sexes (p < 0.01), with boys exhibiting a significantly steeper rise compared to girls. Adiposity variables (BMI z-score, percent body fat, fat mass, waist-to-height ratio) strongly and consistently predicted systolic and diastolic BP in both sexes (all p < 0.05). Systolic BP was also significantly and positively related to height (p < 0.05). No associations with BP were identified in either sex for gonadal hormones or Na:K. Similar results were obtained when BP was classified into hypertension categories. Relative to other developmental and diet-related variables tested, adiposity was found to be the strongest most consistent predictor of BP in pubertal adolescents. Findings highlight the importance of dedicated youth obesity management interventions and policy measures for reducing long-term hypertension and cardiovascular disease risks.Australian New Zealand Clinical Trials Registry ACTRN12617000964314.

Distribution of energy intake across the day and weight loss: A systematic review and meta-analysis.

Consuming a greater proportion of total energy intake earlier in the day rather than in the evening is proposed to positively influence weight loss and health, potentially due to greater synchronization of human body circadian rhythms. This systematic review provides an update on existing evidence regarding earlier distributed eating patterns in weight loss interventions. Using a robust search strategy in five electronic databases, nine randomized controlled trials investigating the impact of energy intake distribution on weight loss were identified. Following critical appraisal, a random-effects meta-analyses found that, in the context of an energy-reduced diet, distributing energy intake with a focus on earlier intake resulted in significantly greater weight loss (-1.23 kg; 95% CI 2.40, -0.06, p = 0.04). Improvements in HOMA-IR, fasting glucose, and LDL cholesterol were also seen. The current study provides a timely update on the evidence linking distribution of total daily energy intake and health, showing that a focus on earlier intakes can result in greater short-term weight loss compared with later intakes. Future studies are needed to elucidate the impact that earlier intakes may have on weight management and metabolic health.

The Future Proofing Study: Design, methods and baseline characteristics of a prospective cohort study of the mental health of Australian adolescents.

OBJECTIVES: The Future Proofing Study (FPS) was established to examine factors associated with the onset and course of mental health conditions during adolescence. This paper describes the design, methods, and baseline characteristics of the FPS cohort. METHODS: The FPS is an Australian school-based prospective cohort study with an embedded cluster-randomized controlled trial examining the effects of digital prevention programs on mental health. Data sources include self-report questionnaires, cognitive functioning, linkage to health and education records, and smartphone sensor data. Participants are assessed annually for 5 years. RESULTS: The baseline cohort (N = 6388, M = 13.9 years) is broadly representative of the Australian adolescent population. The clinical profile of participants is comparable to other population estimates. Overall, 15.1% of the cohort met the clinical threshold for depression, 18.6% for anxiety, 31.6% for psychological distress, and 4.9% for suicidal ideation. These rates were significantly higher in adolescents who identified as female, gender diverse, sexuality diverse, or Aboriginal and/or Torres Strait Islander (all ps < 0.05). CONCLUSIONS: This paper provides current and comprehensive data about the status of adolescent mental health in Australia. The FPS cohort is expected to provide significant insights into the risk, protective, and mediating factors associated with development of mental health conditions during adolescence.

Study protocol: a pragmatic trial reviewing the effectiveness of the TransitionMate mobile application in supporting self-management and transition to adult healthcare services for young people with chronic illnesses.

BACKGROUND: Transition from paediatric to adult heath care services is a challenging time for many adolescents with chronic illnesses and may include deterioration in illness control as a consequence of inadequate self-management skills, poor understanding of their chronic illness and failure to engage with adult services. Successful transfer of health care requires the development of self-management skills and increased autonomy. Mobile technology has been proposed as a modality to assist this process. Evidence is limited and generally restricted to illness specific applications. The TransitionMate app (TMApp) is a generic (non-illness specific) mobile application designed to support young people with chronic illness in their transition from paediatric to adult health care services. The overall aim of the study is to assess the effectiveness of TMApp in improving engagement and retention of adolescents with chronic illness within adult healthcare services, as well as preventing the deterioration in illness control and unplanned hospitalisations. METHODS: The TransitionMate trial is a dual centre, pragmatic, single arm, mixed methods cohort study conducted within two university teaching tertiary paediatric hospitals in Australia. Data collection points are planned at 0, 6, 12 and 18 months. Outcome indicators include: usage of TransitionMate, engagement with adult services, quantitative markers of illness control, and unplanned hospital admissions. Data are collected through telephone interviews with the participants, their primary healthcare providers, electronic medical records and de-identified mobile application analytics. The development of the application involved co-design with recently transitioned young people with a number of chronic illnesses as well as online user experience in younger adolescents. DISCUSSION: The TransitionMate study is the first identified trial of a generic mobile application designed to support adolescents with chronic illnesses during the transition process. Results are expected to provide novel insights into the value of technological tools in the transition space, especially their effectiveness in improving both the transition process and clinical outcomes of adolescents with chronic illnesses. Furthermore, the approach of a pragmatic study design may help identify research methods better designed to overcome inherent challenges in research involving adolescents, transition of care and use of mobile application technology.

A randomized controlled trial evaluating the effectiveness of a self-management program for adolescents with a chronic condition: a study protocol.

BACKGROUND: Self-management support is increasingly viewed as an integral part of chronic condition management in adolescence. It is well recognized that markers of chronic illness control deteriorate during adolescence. Due to the increasing prevalence of long-term chronic health conditions in childhood and improved survival rates of previously life-limiting conditions in children and adolescents, significant numbers of adolescents are having to manage their chronic condition effectively as they transition to adult health care. Therapy adherence has been identified as a major challenge for young people living with a chronic condition such as cystic fibrosis, diabetes, or asthma requiring long-term pharmacological therapy and/or lifestyle modifications. Most systematic reviews on self-management interventions address adult populations. Very few intervention studies are directed at adolescents with a chronic condition who are transitioning to adult health services. This protocol describes a prospective randomized controlled trial of a standardized self-management intervention program delivered to adolescents aged 15-18 years prior to their transfer to adult care. This study has been designed to provide evidence regarding self-management programs for adolescents and is the first study to use the Flinders Program with this important, under-researched age group. METHODS: A randomized controlled trial is used to investigate the effectiveness of a modified adolescent-friendly version of an adult self-management program. This program is directed at improving self-management in an adolescent cohort 15-18 years of age with a chronic condition being treated in a specialist pediatric hospital. Participants will be randomized to either usual care or the modified Flinders Program plus usual care. Data collection will include measures of specific illness control, unscheduled hospital admissions, and questionnaires to record self-management competencies, quality of life, self-efficacy, and outcome measures specific to the chronic condition at baseline, 3 months, 6 months, and 12 months after delivery. DISCUSSION: This study will provide a better understanding of the elements required for effective self-management programs in adolescents with a chronic condition and address some important knowledge gaps in current literature. The study will be carried out in collaboration with the Discipline of Behavioural Health at Flinders University, Adelaide, Australia, in order to inform the development of an adolescent version of the successful and validated Flinders Program™.

Guiding, sustaining and growing the public involvement of young people in an adolescent health research community of practice.

BACKGROUND: Public involvement in health research and its translation is well recognized to improve health interventions. However, this approach is insufficiently practised and evidenced in relation to young people. This paper presents an analysis of the process of co-producing a framework, partnership model and a growing network of young people informing and guiding an adolescent health research community of practice. METHODS: A Living Lab is a participatory research approach that brings together a broad range of stakeholders in iterative cycles of research, design, development, pilot-testing, evaluation and delivery to implement effective responses to complex phenomena. The geographical setting for this study was Sydney, NSW, Australia, and involved both youth and adult stakeholders from this region. The study spanned three phases between July 2018 and January 2021, and data collection included a range of workshops, a roundtable discussion and an online survey. RESULTS: The co-production process resulted in three key outputs: first, an engagement framework to guide youth participation in health research; second, a partnership model to sustain youth and adult stakeholder collaboration; third, the growth of the public involvement of young people with a range of projects and partners. CONCLUSIONS: This study investigated the process of co-producing knowledge with young people in an adolescent health community of practice. A reflexive process supported youth and adult stakeholders to collaboratively investigate, design and pilot-test approaches that embed young people's engagement in adolescent health research. Shared values and iterative methods for co-production can assist in advancing mutual learning, commitment and trust in specific adolescent health research contexts. PUBLIC CONTRIBUTION: Young people guiding and informing an adolescent health research community of practice were involved in this study, and one of the participants is a paper co-author.

A healthy lifestyle text message intervention for adolescents: protocol for the Health4Me randomized controlled trial.

BACKGROUND: Adolescence presents a window of opportunity to establish good nutrition and physical activity behaviours to carry throughout the life course. Adolescents are at risk of developing cardiovascular and other chronic diseases due to poor the complex interplay of physical and mental health lifestyle risk factors. Text messaging is adolescents main form of everyday communication and text message programs offer a potential solution for support and improvement of lifestyle health behaviours. The primary aim of this study is to determine effectiveness of the Health4Me text message program to improve adolescent's physical activity or nutrition behaviours among adolescents over 6-months, compared to usual care. METHODS: Health4Me is a virtual, two-arm, single-blind randomised controlled trial, delivering a 6-month healthy lifestyle text message program with optional health counselling. Recruitment will be through digital advertising and primary care services. In total, 330 adolescents will be randomised 1:1 to intervention or control (usual care) groups. The intervention group will receive 4-5 text messages per week for 6-months. All text messages have been co-designed with adolescents. Messages promote a healthy lifestyle by providing practical information, health tips, motivation and support for behaviour change for physical activity, nutrition, mental health, body image, popular digital media and climate and planetary health. Virtual assessments will occur at baseline and 6-months assessing physical health (physical activity, nutrition, body mass index, sleep), mental health (quality of life, self-efficacy, psychological distress, anxiety, depression, eating disorder risk) and lifestyle outcomes (food insecurity and eHealth literacy). DISCUSSION: This study will determine the effectiveness of a 6-month healthy lifestyle text message intervention to improve physical activity and nutrition outcomes in adolescents.
