2018
Background The prevalence of obesity is higher in those with
intellectual disabilitiesthan the general population. The aim of the study was to understand the determinants of physical activity and dietary patterns in this population during their final year of school. Method Qualitative data were generated from 10 interviews with adolescents with mild–moderate
intellectual disabilities. Data were analysed using deductive
thematic analysis, employing
Self-Determination Theoryas a theoretical framework. Results Adolescents’ environment and social interactions play a pivotal role in influencing physical activity and dietary patterns. Three themes emerged from the analysis: situatedness, motivation and wider environmental influences. Conclusions School structure, high self-efficacy and
social connectednessfacilitate increased physical activity and healthier diet in adolescents with
intellectual disabilities. Home life, low self-efficacy and a lack of
social connectednesscan serve as a barrier to PA and a healthy diet.
