The prevalence of obesity and lifestyle behaviors of parents of youth with intellectual and developmental disabilities.

BACKGROUND

Parents of youth with intellectual and developmental disabilities (IDD) may have a higher prevalence of overweight and obesity and poorer weight management behaviors compared to the general population.

OBJECTIVE

To describe the prevalence of overweight/obesity and related socioeconomic and lifestyle factors including diet quality, physical activity, and reported health habits in parents of youth with IDD.

METHODS

We assessed: BMI (kg/m), moderate-to-vigorous physical activity (MVPA), fruit and vegetable intake (FVI), parental diet and physical activity habits, and socioeconomic characteristics. Associations of BMI on MVPA and FVI were assessed with Spearman's correlation; differences in BMI by parental diet and physical activity habits were assessed with Kruskall-Wallis tests; and the relationships of BMI to household income, race, and education were assessed with Kendall Tau-b and Mann Whitney U tests.

RESULTS

Data was obtained from 110 parents (97.3% female) who were study partners for their adolescents/young adults with IDD participating in a weight loss clinical trial. Approximately 81% of parents were overweight or obese (25.7% overweight, 55.1% obese), with 46.3% and 20% meeting the recommended U.S. guidelines for MVPA and FVI, respectively. Higher FVI and higher income were significantly associated with lower parent BMI. BMI was significantly lower in parents who reported to be physically active and choose healthy food.

CONCLUSION

We observed a high prevalence of overweight/obesity, low FVI and low levels of MVPA in parents of adolescents with IDD. These observations suggest that interventions designed to address these factors have the potential to improve the health and wellbeing of both parents and adolescents with IDD.
