BackgroundConsuming texture‐modified diets was considered to negatively affect health‐related quality of life (HR‐QoL). However, the precise relationship between the levels of food texture consumed and HR‐QoL remains uncertain. The present study aimed to determine the association between levels of food texture consumed and HR‐QoL.MethodsThis cross‐sectional study included 122 hospitalised patients aged ≥ 65 years (mean ± SD age 78.9 ± 7.9 years; 48.4% female) who required postacute rehabilitation. Consumed food texture levels were classified using the International Dysphagia Diet Standardization Initiative (IDDSI) framework 2.0. HR‐QoL was evaluated using the five‐level EuroQoL five‐dimension (EQ‐5D‐5L). The association between food texture levels and HR‐QoL was analysed using a multivariate linear regression model.ResultsThe lower food texture levels consumed were associated with significantly lower EQ‐5D‐5L scores. Consumption of pureed (IDDSI Level 4) and liqudised (IDDSI Level 3) diets were associated with lower EQ‐5D‐5L scores among older patients undergoing postacute rehabilitation (regression coefficient –0.304; 95% confidence interval = −0.472 to −0.137 and regression coefficient, −0.444, 95% confidence interval = −0.676 to −0.213, respectivly).ConclusionsThe findings suggest a link between the consumption of pureed and liquidised diets and lower HR‐QoL scores in older hospitalised patients undergoing rehabilitation. To establish a clearer cause‐and‐effect relationship, future research should encompass multicentre and longitudinal studies, building upon the insights from the present study.
