ABSTRACT
BACKGROUND:
Oropharyngeal dysphagia (OD) is common among older adults. Some studies have evaluated the efficacy of a texture-modified diet on mortality but with short-term follow-up. We aimed to evaluate the effect of a texture-modified diet and controlled bolus volume on all-cause mortality after 12 months in older persons with OD.METHODS:
This secondary analysis of a randomized clinical trial included patients aged ≥60 years with a diagnosis of OD. They were concurrently and randomly assigned to receive either a texture-modified food diet and controlled bolus volume (intervention group) or standard treatment (control group) with 12 months of follow-up. Secondary outcomes were oral intake, weight, handgrip strength, phase angle, and aspiration pneumonia. Kaplan-Meier analysis and the Cox proportional hazards model were used for mortality analysis.RESULTS:
A total of 127 participants (intervention group 64 and control group 63) were recruited, with a mean age of 76 years. The probability of all-cause mortality was significantly lower in the intervention group (n = 8, 12%) than in the control group (n = 18, 29%) (hazard ratio = 0.36 [95% CI = 0.16-0.86]; P = 0.01). There were 5 (7.9%) and 10 (16.1%) aspiration pneumonia events in the intervention and control groups, respectively (not significant) in 12 months of follow-up. Changes were observed in protein consumption (P = 0.01), body weight (P = 0.04), body mass index (P = 0.004), handgrip strength (P = 0.02), and phase angle (P = 0.04) between the treatment groups.CONCLUSION:
Compared with the standard treatment, the dietary intervention improved efficacy by limiting nutrition complications, aspiration pneumonia, and all-cause mortality.
