Patterns of Children's Weight Change During Family‐Based Weight Management Intervention and Associations With Outcome Through Follow‐Up
Authors' conclusion
Three patterns of within-treatment child weight change emerged, with modest consistent weight loss associated with more favourable distal child outcomes.
Study context
- Population
- Children aged 7–11 years with overweight/obesity in behavioural weight management trials
- Participants
- 294 children
- Comparison
- Within-treatment weight change classes
- Primary endpoint
- Class differences in BMI z-score change
- Follow-up
- Through 1 year after treatment
Methodological detailslatent class analysis, latent class modelling, ANCOVA among completers, BCH method accounting for uncertainty in class assignment and missingness

Primary result
As reported in the abstract
Classes of weekly weight change (proportion of children)
Further findings
| Outcome | Difference | P value |
|---|---|---|
| BMI z-score change during follow-upConsistent modest weight loss vs Moderate to decreasing weight loss · ANCOVA | −0.096 | P = 0.05 |
| BMI z-score change during follow-upConsistent modest weight loss vs Larger loss to stable weight · BCH | −0.144 | P = 0.017 |
| BMI z-score change from baseline through follow-upConsistent modest weight loss vs Larger loss to stable weight · ANCOVA | −0.189 | P = 0.080 |
| BMI z-score change from baseline through follow-upConsistent modest weight loss vs Larger loss to stable weight · BCH | −0.186 | P = 0.015 |
BMI z-score change during follow-up
- Consistent modest weight loss class showed minimal change in BMI z-score whereas the other two classes increased
