Characteristics of achieving clinically important weight loss in two paediatric weight management interventions

Summary Objective To examine characteristics and lifestyle behaviours associated with achieving clinically important weight loss (CIWL) in two paediatric weight management interventions (PWMIs). Methods We examined 1010 children enrolled in the STAR and Connect for Health trials. We defined achieving CIWL as any participant who had decreased their BMI z‐score by ≥0.2 units over 1 year. Using log‐binomial regression we examined associations of child and household characteristics and lifestyle behaviours with achieving CIWL. Results In multivariable analyses, children with severe obesity had a lower likelihood of achieving CIWL compared to children without severe obesity (RR: 0.68 [95% CI: 0.49, 0.95]). Children who were ≥10 years were less likely to achieve CIWL (RR: 0.56 [95% CI: 0.42, 0.74]) vs those 2‐6 years of age. Children who consumed
