Parent–Child Sex Composition Impacts Long‐Term Outcomes in Family‐Based Behavioural Treatment
Authors' conclusion
Parent-child sex composition meaningfully influences children's long-term response to FBT. Opposite-sex dyads, particularly father-daughter pairs, show more sustained benefits.
Study context
- Population
- Families provided with Family-Based Behavioural Treatment (FBT)9 randomised FBT trials
- Comparison
- Opposite-sex vs same-sex parent–child dyads
- Primary endpoint
- Change in child zBMI and clinically meaningful weight outcomes (≥ 0.25 reduction in child zBMI; ≥ 5% parent weight loss)
- Follow-up
- two-year follow-up
Methodological detailspooled from 9 randomised FBT trials (1981–2013)
- Pooled from 9 randomised FBT trials (1981–2013)
Primary result
As reported in the abstract
Child zBMI change and clinically meaningful change · 2 years
- Children, but not parents, in opposite-sex dyads showed larger reductions in zBMI and greater odds of clinically meaningful change across 2 years
Further findings
Clinically meaningful reductions by four dyad combinations
- Daughters in mother-daughter dyads had the lowest odds of clinically meaningful reductions; daughters in father-daughter dyads had the highest
