Does deciding not to participate in a lifestyle intervention for children with obesity affect the long‐term weight change?
Main finding · Annual change in BMI z scoreResult — go to the resultDifference 0.00 per year 95% CI −0.03 to 0.03Authors' conclusion
Children deciding not to participate in an intervention did not increase their weight compared with children who were never invited, indicating that treatment could be briefly postponed until families are able to participate. Additionally, socioeconomic status or immigration background did not modify the weight change.
