Summary Background Scant data exist on weight loss interventions for youth with intellectual disabilities (ID). Objective To compare weight loss among youth with ID randomized to a 6‐month, family‐based behavioural intervention (FBBI) or a waitlist and to compare weight loss among youth who completed a 6‐month maintenance (FBBI‐M) intervention to a control group (FBBI‐C). Methods Youth with ID and overweight/obesity, aged 14‐22 years, were randomized to the FBBI or to a waitlist and subsequently randomized to a maintenance intervention or a control group. Sessions were held weekly during the FBBI and biweekly during the FBBI‐M. Using an intention‐to‐treat approach, we used linear mixed models to test differences in the change in weight and in BMI from the start of FBBI. Results The 24 participants who received the FBBI lost, on average (SE), 5.1 (1.1) kg ( P < .001) over 6 months. The 13 participants who were waitlisted gained, on average (SE), 1.2 (1.6) kg over the 6‐month waiting period. At 12 months, those who received FBBI‐M lost, on average (SE), 4.4 (1.7) kg more than those who received FBBI‐C (−7.6 vs −3.2 kg, P ‐value = .008). Conclusion Participation in an intensive FBBI for weight loss with ID was efficacious, and continued participation in a maintenance intervention yielded additional weight loss.
