Identify factors related to F&V intake.

Blood cholesterol, body mass index (BMI), blood pressure (BP), heart rate (HR), consumption of F&V, food purchasing/preparation, outcome expectations, self-efficacy, supports, reported by adults with I/DD/informants.

This study analysed data from 67adults with I/DD.

45% of participants consumed less than two servings of F&V/day, 65% had little/no involvement in food preparation/shopping/meal planning, 27% reported the food they eat as unhealthy/10% don’t like food they eat. Using ANOVA, people eating fewest F&V had lowest self-efficacy (F=5.39, p=0.000). People living independently had lowest self-efficacy and consumed the least amount of F&V (F=2.96, p=0.039). F&V intake was negatively correlated with BMI (p< 0.0001), BP (p=0.003), and HR (p=0.037).

Health promotion programs should aim at increasing self-efficacy among adults with I/DD to be more involved with food preparation and caregivers to provide support in making healthy food choices.
