Ready-to-use modified-texture food (rMTF) products are commercially available and may have greater appeal than conventional in-house or commercial bulk modified-texture food (cMTF) products. A nine-month pilot study using a prospective interrupted time-series design where participants (n = 42) served as their own controls investigated the impact of cMTF + rMTF on weight goals, weight, food intake, and co-morbidity. Seventy-four per cent of participants achieved their weight goals at the end of six months on rMTF and, although insignificant, participants did have a trend towards weight gain while on rMTF (OR 3.5 p = .16). Main-plate food intake (grams) was not significantly different over time, but a downwards trajectory suggests decreased consumption that was compensated for by a significantly higher fat intake during the intervention period (p = .01). Increased co-morbidity and a decreasing volume of food consumed are common in older adults with dysphagia, and enhanced food products are needed to meet nutrient needs. Methodological issues encountered in this study can provide guidance for future work.


Les aliments à texture modifiée prêts à servir (ATMp) sont offerts commercialement et peuvent être plus attrayant que les produits conventionnels maison ou commerciaux en vrac. Une étude prospective de neuf mois utilisant l’approche de séries temporelles interrompues, où les participants (n = 42) agissaient comme leur propre témoin, a examiné l’impact des ATMp sur le poids, les objectifs de poids, l’apport alimentaire et les comorbidités. Soixante-quatorze pour cent des participants ont atteint leurs objectifs de poids à la fin d’une période de six mois où ils consommaient les ATMp. Il était plus probable, mais pas statistiquement significatif, que les participants ont eu un gain de poids pendant l’intervention (6 mois) comparé à la période de contrôle (3 mois) offrant la diète d’aliments conventionnels (ATMc) (RC 3.5, p = .16). L’apport alimentaire (en g) n’a pas différé de façon significative à travers l’étude. Cependant, la pente légèrement négative pourrait être expliquée par une consommation significativement supérieure de gras pendant l’intervention (p = .01), ce qui a aidé à maintenir le poids des participants. L'augementation des comorbidités et une réduction de la consommation alimentaire sont communs chez les personnes âgées atteintes de dysphagie. Des aliments fortifiés en nutriments sont nécessaires pour combler leurs besoins nutritionnels. Les questions méthodologiques rencontrées dans la conduite de cette étude peuvent orienter les travaux futurs.
