Edentulism and number of medications are associated with nutritional status in older adults: a population-based cross-sectional study

Abstract

Objective: This study evaluated the nutritional status and associated factors among older adults of a southern Brazilian city. Methods: A cross-sectional home-based study, with a probabilistic sample per cluster, was carried out with 282 older adults aged ≥60 years in the city of Veranópolis, Brazil. Through a structured questionnaire, socioeconomic, general and behavioral health aspects were assessed. Nutritional status was assessed using the Mini Nutritional Assessment (MAN®) instrument, categorizing the sample into eutrophic or nutritional risk (risk of malnutrition + malnourished). Oral health was assessed by counting teeth and the use of and need for dental prosthesis. Two independent multivariate models were constructed, using number of daily medication and polypharmacy (≥2 daily medications). Logistic regression was used to verify associations. Results: The prevalence of nutritional risk was 14.5% (N=41). In the final multivariate analysis, users of ≥6 daily medications demonstrated a greater odds ratio (OR) of being at nutritional risk when compared to those who did not use medication daily (OR: 12.16; 95% confidence interval [95%CI]: 1.47 – 100.82). Non-edentulous older adults had 67.7% (p = 0.006) lower OR for nutritional risk when compared to edentulous. Conclusion: The prevalence of nutritional risk was low among this sample, and it was associated with edentulism and number of daily medications.
