Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is a family-focussed lifestyle, nutrition and well being weight management program. This program is based on standard practice and clinical practice guidelines for weight management for children and adolescents. The intervention has been co-designed by parents of children with Duchenne muscular dystrophy (DMD) and neuromuscular clinicians.

The intervention will be delivered via an Australian paediatric neuromuscular clinic. The intervention will include sessions with a dietitian specialised in paediatric weight management. Sessions will be a combination of face-to-face and phone or video calls, at the participants discretion. Sessions will be conducted weekly over a 6 week intervention period. There will be a 6 week post-intervention period with 12 weeks follow up in total.

The program outline is as follows:
* Session 1 (wk 0) - baseline measures & dietetic counselling session (90 mins)
* Review 1 (wk 1) - brief review via phone or face-to-face (20 mins)
* Session 2 (wk 2) - dietetic counselling session via phone or face-to-face (60 mins)
* Review 2 (wk 3) - brief review via phone or face-to-face (20 mins)
* Session 3 (wk 4) - dietetic counselling session via phone or face-to-face (60 mins)
* Review 3 (wk 5) - brief review via phone or face-to-face (20 mins)
* Session 4 (wk 6) - outcome measures & dietetic counselling session (90 mins)
* Session 5 (wk 12) - outcome measures (30 mins)

Dietetic counselling session will be individual and tailored to each family and will include nutrition education and goal setting. Written resources will also be provided to participants and their families on: nutrition topics, managing appetite, mindfulness, recipe ideas and nutrition supplements. Resources that are readily available from internet sources will be used. Families will also have access to online support from the dietitian.

Statistical methods / analysis
This is a pilot study and not powered for statistical changes in parameters.

Baseline characteristics will be presented for all participants eligible for analysis and will not be stratified. The difference in weight, BMI, 10m walk/run time, supine-to-stand time, can stacking exercise time, systolic and diastolic blood pressure, PedsQL DMD and dietary intake between baseline and week 6 and week 12 will be assessed using a repeated measures ANOVA or a non-parametric equivalent and be presented as mean change with standard deviation or median change with inter-quartile range.

Global Rating of Change responses will be reported frequencies (categorical data) at week 6 and week 12. Step count will be reported as a weekly mean across each week of the intervention and follow-up periods, no statistical analysis will be performed for step-count.

Post-program and withdrawal questionnaires will be analysed as frequencies for categorical data. Open-ended responses for the post-program and withdrawal questionnaires will not be formally analysed, however quotes may be used in the dissemination of findings and to inform future research studies.

Data will be analysed with SPSS software (IBM Corp. Released 2016. IBM SPSS Statistics for Windows, Version 24.0. Armonk, NY: IBM Corp). For all analysis a p-value of <0.05 was considered to be statistically significant.

Summary
Brief summary
This is a single-arm, uncontrolled feasibility and pilot study of a lifestyle weight management program for Duchenne muscular dystrophy (DMD). The aims of this study are to:
* assess feasibility and acceptability of SNOW-P
* determine the impact of SNOW-P on: weight, BMI, physical function, physical activity level, blood pressure, quality of life, fatigue, dietary intake and adverse events

This study will recruit young people with DMD who have obesity.

The expected outcomes for this study will be improved understanding of how to manage obesity in DMD and improved nutrition and wellbeing for young people after participating in a weight management program.
