Associations between parent and adolescent weight outcomes within two parent approaches to family‐based adolescent obesity treatment: Secondary analyses from the TEENS+ pilot trial
Authors' conclusion
Parent and adolescent weight changes were positively related during treatment in both parent groups. During maintenance, weight change associations persisted only in PAC. These patterns prompt further exploration of parent factors driving weight change relationships.
Study context
- Population
- Adolescents with obesity (mean age 13.7 ± 1.2 years; mean BMI 34.9 ± 7.0 kg/m²) and their parents (mean BMI 36.4 ± 7.3 kg/m²)
- Participants
- 82 parent–adolescent dyads
- Comparison
- TEENS+Parents as Coaches vs TEENS+parent weight loss
- Primary endpoint
- Association between parent and adolescent ΔBMI (0–4 m and 4–7 m), with parent group as moderator
- Follow-up
- 4 months (post) and 7 months (after 3-month maintenance)
Methodological detailsfamily-based, moderation analysis, Anthropometrics assessed at baseline, 4 months (post) and 7 months (after 3-month maintenance)
- Family-based
- Moderation analysis
- Anthropometrics assessed at baseline, 4 months (post) and 7 months (after 3-month maintenance)
Primary result
As reported in the abstract
- Parent vs adolescent ΔBMI0-4m, post-treatment (β); no group interaction
- β = 0.68, p < 0.001
- Parent vs adolescent ΔBMI4-7m, maintenance (β)
- β = 0.48, p = 0.012
- Moderation by parent group, ΔBMI4-7m (β)
- β = −0.49, p = 0.010
- ΔBMI4-7m association in PAC (β)
- β = 0.39, p = 0.011
- ΔBMI4-7m association in PWL (β)
- β = −0.19, p = 0.211
