Fröhlich and colleagues analyzed weight changes in patients with overweight or obesity aged 7–15 years, in 111 parent–child dyads who participated in a 1–year lifestyle intervention program. Failure (<5% weight reduction) at 1 year after conclusion of the program was best determined by maternal depression, with maternal insecure–anxious attachment attitudes being the best failure predictor between the conclusion of the program and the 1-year follow-up.
