Plain English summary of protocol
Background and study aims
In 2016, more than 1.9 billion adults and over 340 million children and adolescents aged 5-19 were overweight/obese globally. Overweight and obesity are defined as as abnormal or excessive fat accumulation that may result in physical, social, emotional, and mental health complications. The involvement of parents and children in interventions such as health education coaching and programs may help to reduce obesity and promote long-term healthy weights among members of the family. Children's parents, home and family environments are some of the strongest influences on their health behaviours, which means that one of the best ways to encourage positive health behaviour is to target parents and children whilst children are still young.
The aim of this study is to look at how a 3 month health education and coaching program can affect changes in physical activity and nutrition in overweight/obese parents, along with changes in parental motivation to engage in healthy behaviours.
Who can participate?
Overweight/obese parents with children between the ages of 2.5-10 years old (of any weight) who live in Middlesex County and live together for at least 5 days of the week
What does the study involve?
Pairs of parents and children will be randomly assigned into either the intervention or control group. Both groups will receive 6 online health education sessions. The intervention group will also receive 9 20 minute telephone-based coaching sessions. Participants will be assessed on their physical activity, nutrition, self-esteem and their perceptions of the program's efficacy.
What are the possible benefits and risks of participating?
The potential benefits from this program include information and/or coaching provided to participants, along with the long-term health behaviour changes within the family that this program aims to promote. There are no known risks for participating in this study. Although it is not anticipated, it is possible that some individuals may feel sensitive speaking about their personal experiences. If parent-participants feel they would like to share their feelings with individuals outside of the study environment, they are being advised to seek resources available in London and area (e.g. London Middlesex Counselling and Addiction Services).
Where is the study run from?
Western University in London, Ontario, Canada.
Some follow-up measurements occur at participants’ homes, if they choose.
When is the study starting and how long is it expected to run for?
June 2017 to June 2019
Who is funding the study?
Institute of Coaching (USA)

| Scientific title | Coaching and/or education intervention for parents with overweight/obesity and their children: a randomised controlled trial |
| Study objectives | Primary research question: What is the impact of 3 months of coaching plus health education compared to health education only on: 1. The physical activity (PA) levels of children (ages 2.5-10) and their parents with overweight (i.e., BMI of > 25 kg/m²)? 2. The dietary intake of children and their parents with overweight? 3. Parental motivation to engage in healthy behaviours? Secondary research question: What is the impact of coaching plus health education compared to health education only on parental: 1. Body Mass Index (BMI)? 2. Overall perception of health? 3. Psychosocial variables (i.e., social support, self-esteem, and self-efficacy)? 4. Perceptions of the intervention’s impact on themselves, their child, and their family? We hypothesise that immediately following, and at 6 months post-intervention, the coaching plus education group will report higher levels of parent-child physical activity, greater improvements in parent-child dietary intake choices, greater parental psychosocial benefits, and greater improvements in parents’ BMI values, compared to those who receive education only. We predict that parents from higher SES (socioeconomic status) backgrounds will be more favourably impacted than those from lower SES backgrounds, as researchers have found greater difficulties associated with affecting behaviour change within lower SES environments (Peters, Parletta, Lynch, & Campbell, 2014). It is also hypothesized that male parents and children will report higher PA levels, while female parents and children will report greater dietary intake improvements, and their psychosocial health will be most positively impacted, given that previous research has found young males tend to be more active than their female counterparts, and obesity affects psychosocial health of women more negatively than men (Walker & Hill, 2009). |

| Health condition(s) or problem(s) studied | Overweight/obese parents and their children (ages 2.5-10 years) of any weight. |
| Intervention | 50 parent-child pairs will be randomly assigned, using a 1:1 ratio, to either the intervention group or control group. A computerized program will be used to determine participant assignment. As participants become eligible, they will be assigned to the next available slot, which will indicate which group they are assigned to. For instance, when using the website http://www.graphpad.com/quickcalcs/randomize1/ to randomly assign participants, it asked for the number of subjects in the study and how many groups they need to be randomly assigned to, and from this, it generated random assignment for that amount of subjects (e.g. Participant 1 = Group A, Participant 2 = Group B, Participant 3 = Group B, etc). For the purposes of this research, Group A will be the intervention group and Group B will be the control group. Group A will receive 9 20-minute telephone-based coaching sessions for parents, plus 6 online education sessions. They will create a schedule with their coach to receive these sessions, with 3 per month for 3 months. The agenda of the sessions will be of the participant's choosing. The 6 online health education sessions will consist of 3 sessions focused on physical activity and 3 sessions focused on healthy eating, all of which are created by the research team. These will be open to participants upon entry to the study, and parents will be asked to engage in their next lesson approximately 7-10 days after their previous one. The uptake of each lesson will be tracked by participant login and duration, and by a “What is the most important lesson I took from this session” question that they will be asked to complete and submit at the end of each module. Group B will receive the same 6 online education sessions received by the intervention group. Assessments will be conducted at baseline, 6 weeks into the intervention, post-intervention (3 months), and 6 months post-intervention. |
