Task: Question Answering
Input (English): Context: Both diet quality (DQ) and physical activity (PA) have been shown to play a role in the prevention of functional capacity (FC) decline. Because older adults (OA) with T2D are at a higher risk of FC decline compared to their non-diabetic counterparts, our aim was to determine if DQ alone, or combined with PA is associated with FC decline in OA with T2D over a 3-year follow-up in a secondary analysis of the NuAge cohort.', "In 159 OA with T2D (mean age=75 years), FC change was calculated as the difference in FC scores at T1 and T4 measured by the SMAF (Système de Mesure de l'Autonomie Fonctionnelle). Baseline DQ was calculated from three non-consecutive 24-h dietary recalls collected at T1 using the validated Canadian Healthy Eating Index (C-HEI). PA change was calculated from Physical Activity Scale for the Elderly (PASE) as T4-T1. Associations were evaluated between FC decline and four combinations of variables: C-HEI score < or ≥70 with PASE change < or > median and analyzed by GLM while controlling for covariates.", 'Neither DQ alone nor DQ combined with PA change were associated with FC decline over follow-up.\Question: Is decline in functional capacity unaffected by diet quality alone or in combination with physical activity among generally healthy older adults with T2D from the NuAge cohort?
Output (English): The absence of effect may be explained by characteristics of this healthy sample of OA with T2D who showed relatively good adherence to dietary recommendations (mean C-HEI=70) and were highly functional shown by minimal, clinically non-significant FC decline over 3 years. More research is needed to confirm the role of DQ in preventing FC decline in a larger diabetic sample showing clinically significant FC decline.
