Physical Activity and Sedentary Time in Active and Non-Active Adults with Intellectual Disability: A Comparative Study

Abstract

This study describes and compares physical activity (PA) levels and sedentary time (ST) of active (AG) and a non-active (NAG) groups of adults with intellectual disability (ID) versus a group of adults without ID. Thirty-seven participants from the AG, 29 from the NAG, and 31 adults without ID participated in this study. Height and weight were obtained to calculate body mass index (BMI). PA levels and ST were assessed with GT3X Actigraph accelerometers for 7 days. Results revealed that the AG engaged in higher values of moderate to vigorous PA compared with the NAG (all p < 0.05), but were similar to adults without ID. Adults without ID performed less ST and more light PA than the ID groups (all p < 0.05). The participants of the AG did not demonstrate less ST than the NAG. It is concerning that adults with ID (AG or NAG) are spending a higher time in ST and less time in light PA than adults without ID. Our results suggest that integrated, well-designed PA programmes into the ID population workdays can lead to increased PA levels. Nevertheless, these interventions and exercise programmes implemented for adults with ID should be tailored to also reduce ST.
