The problem
Intervention: 10-week intensive multicomponent lifestyle camp focused on physical activity, nutrition, well-being, peer interaction, and social belonging
Who it was tested with: 222 vulnerable children aged 7-14 years (mean 12.3 years) referred for overweight/obesity and/or psychosocial issues; 126 (57%) completed 3-year follow-up assessment.
The same group is measured before the intervention and again afterwards, with a baseline and an endline and sometimes a midline. Change is visible, but other causes cannot be ruled out.
"Mixed-effects models were performed to assess longitudinal changes in anthropometry and QoL and explore if improvements achieved during the lifestyle intervention predicted long-term outcomes" with measurements at baseline, end-of-treatment, and 3-year follow-up. The pre-post design with repeated measurements allows assessment of change trajectories, though the lack of a control group and high attrition limit causal inference.
Nonrandomized design without comparison group prevents causal attribution; 57% attrition at follow-up introduces selection bias; unclear whether improvements would have occurred naturally without intervention; majority of participants retained overweight/obesity status despite intervention
