Introduction: Caregivers of adults with IDD often play a large role in the ability of adults with IDD to lose weight.
Objective: The purpose of this study was to determine to examine the effects of the caregivers' perceived burdens and self-efficacy and their relationship to an individual (family member or paid staff) on weight changes across a weight management intervention for adults with IDD.
Methods: Overweight/obese adults with mild to moderate IDD, along with assigned caregivers who served as their study partner, were randomized to an 18-month weight management intervention. The living environment and caregiver relationship were assessed at baseline. Caregivers completed questionnaires regarding perceived hassles, uplifts, and self-efficacy in helping the participant follow a weight management intervention.
Results: 147 adults with IDD (∼57% women and ∼16% minorities) were included in data analysis. After 18 months, there were no differences in weight loss between participants who had a family member as their study partner and those who had a paid assistant as their study partner (-5.5 ± 5.2% vs. -5.6± 5.3% p = 0.16). However, paid assistants reported more hassles with following the diet intervention at 6 months (p < 0.05). Participants who had a paid assistant as their study partner were more likely to have multiple study partners during the study, which was correlated with smaller weight loss.
Conclusion: While caregivers are important for weight management of adults with IDD, the caregiver's relationship to the participant does not affect weight change in an intervention.
