Bambú multicomponent early parenting program to prevent childhood obesity in vulnerable families

Official title: Evaluation of a Tailored Multicomponent Early Intervention for Childhood Obesity Prevention in Vulnerable Families (Bambú Project): Randomized Controlled Trial With a Hybrid Type 1 Effectiveness-implementation Design

Run by Avedis Donabedian Research Institute · NCT07529704 · Data updated 2026-11-12

This program tests whether the Bambú multicomponent early parenting intervention in primary care can help prevent excess weight in children aged 6 months to 3 years from vulnerable families where at least one parent has overweight or obesity.

Is this trial a fit for you?

Likely a good fit

Primary caregivers aged 18 or older of a healthy term child aged 6 months to 3 years, living in vulnerable socioeconomic circumstances and with at least one parent who has overweight or obesity are ideal candidates.

Probably not a fit

Families with children born at low birth weight (<2500 g), from multiple births, or who do not meet the defined vulnerability criteria or cannot attend participating Spanish primary-care sites are unlikely to benefit from this intervention.

What this trial studies

This randomized primary-care intervention compares the Bambú multicomponent parenting program to usual care in families identified as socioeconomically vulnerable and with at least one parent having overweight or obesity. The main outcome is children's BMI-for-age z-score measured at baseline and at 6, 12, and 18 months, with secondary outcomes including responsive feeding, dietary intake, parent and child physical activity, parental eating styles, and child sleep. The intervention is adapted to families' socioeconomic context and delivered through primary-care settings. Eligible participants are primary caregivers aged 18+ of a healthy term child aged 6 months to 3 years who meet predefined vulnerability criteria.

Why it matters

Potential benefit: If successful, the program could help children maintain a healthier weight and establish better feeding, activity, and sleep habits that reduce long-term obesity risk.

How similar studies have gone: Previous randomized early-life multicomponent parenting interventions have shown mixed but promising results for modest reductions in childhood overweight, so this approach builds on emerging evidence but is not yet definitive.
