What this trial studies

This project evaluates the effectiveness of the Health4Life app, a digital intervention designed to support parents in fostering healthy lifestyle behaviors in their infants from birth. The study employs a randomized controlled trial with a hybrid implementation-effectiveness design, focusing on children's dietary intake, screen time, physical activity, sleep, and body mass index (BMI) z-scores over a 16-month period. Additionally, it assesses parental self-efficacy and the cost-effectiveness of the app, while exploring its acceptability and feasibility within primary child healthcare settings in Sweden.

Good fit: Ideal candidates for this study are parents of infants aged 0-2 months attending routine visits at selected child healthcare centers in Sweden.

Not a fit: Patients who may not benefit from this study include infants with neurological or endocrine disorders or those from families unable to understand the app's content.

Why it matters

Potential benefit: If successful, this intervention could significantly reduce the risk of overweight and obesity in children by promoting healthy habits from an early age.

How similar studies have performed: Other studies have shown success with similar digital interventions aimed at promoting healthy behaviors in children, indicating potential for positive outcomes.
