Effects of a dietetic treatment in older , undernourished , community-dwelling individuals in primary care : a randomized controlled trial . PURPOSE Undernutrition is a prevalent problem in older , community-dwelling individuals . Aim of this study was to determine the effects of a dietetic treatment in older , undernourished , community-dwelling individuals . METHODS A parallel randomized controlled trial was performed in 146 non-institutionalized , undernourished individuals aged ≥65 years in primary care . Participants were randomly assigned to the intervention ( referral to and treatment by a trained dietitian ) or control group ( no referral ) . Body weight , physical performance , handgrip strength , energy intake , protein intake and fat-free mass were assessed at baseline , after 3 months and after 6 months . RESULTS All randomized participants ( n = 146 ) were included in the intention-to-treat generalized estimating equations analysis ( 72 in intervention and 74 in control group ) . No treatment effect was found on the primary outcomes body weight ( β = 0.49 kg , 95 % CI : -0.15-1.12 ) , physical performance ( β = 0.15 points , 95 % CI : -0.33-0.64 ) and handgrip strength ( β = 0.49 kg , 95 % CI : -0.62-1.60 ) . Furthermore , no treatment effect was found for the secondary outcomes . Predefined subgroup analyses showed a treatment effect on body weight in physically active participants ( β = 1.25 kg , 95 % CI : 0.70-2.11 ) and not in inactive participants ( β = -0.20 kg , 95 % CI : -1.16-0.75 ) . CONCLUSIONS After 6 months , a dietetic treatment by trained dietitians does not lead to increases in body weight and physical functioning in older , undernourished , community-dwelling individuals .
