Background and objectives: The number of older adults is increasing rapidly in Vietnam. They suffer from various health problems, including malnutrition and dysphagia. By using a simple screening questionnaire such as the Mini Nutritional Assessment - Short Form (MNA-SF) and 10-item Eating Assessment Tool (EAT-10), nutritional and dysphagic status were screened in this study. The study aimed to determine the prevalence of and relationship between malnutrition and dysphagia in Vietnamese older adult inpatients.
Methods and study design: The study was designed as a cross-sectional study and conducted in three large hospitals in northern Vietnam. The data about nutritional status and dysphagia status of 1007 older inpatients were collected by dietitians.
Results: There were 71.6% of subjects at malnourished (MNA-SF score <8) and risk of malnutrition (MNA-SF score: 8-11). The prevalence of dysphagia by EAT-10 was 24.6%. The risk of dysphagia was independently associated with higher risk of malnutrition, with an odds ratio of 3.21 (95% CI: 1.93-5.31, p<0.001). In addition, malnutrition was also an independent predictor for risk of dysphagia, with an odds ratio of 3.09 (95% CI: 1.84- 5.17, p<0.001).
Conclusions: Malnutrition and dysphagia prevalence were high; and malnutrition and dysphagia have a strong relationship among older adult inpatients in Vietnam. Therefore, nutritional and dysphagia screening at hospital admission are very important and recommended.
