RESUMO
BACKGROUND/OBJECTIVES: Oropharyngeal dysphagia (OD) is a common problem in elderly population that negatively affects the oral intake and body composition resulting in clinical complications as malnutrition and dehydration. The aim of this study was to design, implement, and evaluate the effect of texture-modified foods and thickened drinks diet, with nectar or pudding viscosity and controlled bolus volume in older adults with OD on body composition and oral intake. SUBJECTS/METHODS: Randomized clinical trial, simple blind. Patients ≥ 65 years, admitted at a national institute, who had a confirmed diagnosis of OD were included. A texture-modified foods and thickened drinks diet, with nectar or pudding viscosity and controlled bolus volume, was compared to isocaloric standard treatment for 12 weeks. Body composition was evaluated by bioelectrical impedance, muscular functionality was evaluated by handgrip strength, and daily energy and protein intake by 24-h recall and evaluated by Food Processor Nutrition Analysis® software. RESULTS: Twenty participants were included per group, with mean age 76 years. After 12 weeks, the consumption of energy (29 ± 10 to 40 ± 15 kcal/kg, p = 0.009) and protein (1.3 ± 0.6 to 1.8 ± 0.7 g/kg, p = 0.03), as well as phase angle (4.4 ± 1.8 to 5.5 ± 2.5°, p = 0.05), body weight (56 ± 10 to 60 ± 10 kg, p < 0.001), and handgrip strength (18 ± 11 to 21 ± 13 kg, p = 0.004) increased in the intervention group. In control group there were no changes. CONCLUSIONS: The dietary intervention improved oral intake, weight, handgrip strength, and phase angle, which can prevent or limit the nutritional complications associated with the OD.
