People with mental disabilities

Sound health is critical to quality of life (Skevington, 2007). Acquisition of skills in self-determination and independence are integral to quality of life. Two facets that engender self-determination and independence for an individual are healthy food choice and food preparation (Koponen et al., 2019; Yaddaden et al., 2019). However, healthy food choice and food preparation have received scant attention as individuals with intellectual and developmental disabilities (IDD) continue to face health disparities and poor health status. The purpose of this dissertation was to explore single subject experimental studies conducted on healthy food choice and food preparation from 2005 to 2022 in peer-reviewed journals. The methodology utilized a journal hand search, database search, and ancestral search. The results indicate that of the combined search of over 75,000 articles, less than 1% involved healthy food choice and/or food preparation. The results also illuminate the paucity of the research on healthy food choice and reveal that food preparation is gaining more attention in the empirical literature. The limitations of the study and implications for practice and research are also discussed.

In this study, physiological and psychological outcomes of an 8-week moderate to vigorous aerobic exercise program (Zumba®) for adults with intellectual and developmental disabilities (IDD) were examined. Forty-six participants were randomly assigned to the experimental group (n = 24) or control group (n = 22). The experimental group participated in Zumba® for 8 weeks, 3 days per week, along with completing exercise rating scales and fitness tests. Outcome measures included agility, endurance, rate of perceived exertion (RPE), exercise motivation, and exercise self-efficacy.
Agility, endurance, and RPE were measured by three fitness tests; Timed Up and Go (TUG) test, the Six-Minute Walk Test (6MWT), and Modified Borg Dyspnoea (MBD). Physiological outcomes were measured before the intervention (pretest), 4 weeks during the intervention, and after the intervention (posttest). The experimental group completed a follow-up of all three fitness tests 2 weeks after the removal of the intervention. A paired t test assessed the continuous measures within each group.
