Brief summary
The overall aim of this project is to evaluate the effectiveness and implementation of a digital intervention to support parents to create healthy lifestyle behaviours from the start of their infant's life, in order to prevent overweight and obesity. Using a randomized controlled trial with a hybrid type I implementation-effectiveness design we will: 1. evaluate the effectiveness of the 16-month Health4Life intervention on: 1. Children's' dietary intake, screen time, physical activity, and sleep 2. Children's body mass index (BMI) z-scores 3. Parental self-efficacy 2. Evaluate the cost-effectiveness of the Health4Life app. 3. Evaluate and explore the implementation of the Health4Life app within primary child healthcare with regards to its: 1. acceptability, appropriateness, and feasibility according to child healthcare nurses. 2. satisfaction and usage by parents.
Interventions
BEHAVIORALHealth4Life app

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Screen time | Baseline, mid-intervention (i.e., 8 months after baseline), and post-intervention (i.e., 16 months after baseline) | Time spent watching screens (min/day) |
| Total physical activity | Post-intervention (i.e., 16 months after baseline) | Total number of minutes spent in physical activity (min/day) assessed with accelerometers. |
| Sleep | Post-intervention (i.e., 16 months after baseline) | Total amount of time spent sleeping (min/day) measured with accelerometers. |
| Intake of key dietary indicators | Post-intervention (i.e., 16 months after baseline) | Intake of dietary indicators such as fruit, vegetables, sweet snacks, savoury snacks, and sugar sweetened beverages (portions or grams per day) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Satisfaction of the app (Interviews) | Post-intervention (i.e., 16 months after baseline) | Semi-structured interviews with parents |
| Usage of the app (Questionnaire) | Post-intervention (i.e., 16 months after baseline) | Questionnaire to all parents in the intervention group |
| Usage of the app (Interviews) | Post-intervention (i.e., 16 months after baseline) | Semi-structured interviews with parents |
| Usage of app by parents (measured objectively through the app) | Post-intervention (i.e., 16 months after baseline) | Number of times they went in the app, number of read messages, and number of quizzes completed. |
| Approritateness of the app | Post-intervention (i.e., 16 months after baseline) | Semi-structured interviews with child healthcare nurses |
| Feasibility of the app | Post-intervention (i.e., 16 months after baseline) | Semi-structured interviews with child healthcare nurses |
| Accetability of the app | Post-intervention (i.e., 16 months after baseline) | Semi-structured interviews with child healthcare nurses |
| BMI | Post-intervention (i.e., 16 months after baseline) | weight (kg) / height (m)\^2 |
| Parental self-efficacy to promote healthy diet and physical activity behaviours in their child | Baseline, mid-intervention (i.e., 8 months after baseline), and post-intervention (i.e., 16 months after baseline) | Parental self-efficacy for promoting healthy physical activity and dietary behaviours in children scale questionnaire. Minimum score = 0, Maximum score = 160, a better score indicates a better outcome |
| Satisfaction of the app (Questionnaire) | Post-intervention (i.e., 16 months after baseline) | Questionnaire to all parents in the intervention group |
