Nutritional Assessment and Factors Associated to Malnutrition in Older Adults: A Cross-Sectional Study in Bogota, Colombia

Objective: To determine the nutritional status and factors associated to malnutrition in older adults. Method: Data come from the SABE Bogota study (Health, Well-Being, and Aging), a cross-sectional survey conducted in Bogota, Colombia, in 2012 in community-dwelling adults aged 60 years and older. Using the Mini Nutritional Assessment (MNA), we evaluated the nutritional status and factors associated to malnutrition in this population with regression models. Results: From the 1,573 older adults interviewed, 4.58% were malnourished and 34.27% were at risk of malnourishment. Factors associated to malnourishment were older age (odds ratio [OR] =1.02, 95% confidence interval [CI] = [1.00, 1.04]), perceived poor health (OR = 1.46, 95% CI = [1.13, 1.88]), comorbidities (OR = 1.16, 95% CI = [1.04, 1.30]), and low calf circumference (OR = 2.63, 95% CI = [1.86, 3.72]). Having dentures, perception of being well-nourished, and higher functionality decreased the odds for malnourishment (p < .05). Conclusion: The MNA is useful to evaluate factors associated with malnutrition among older adults in Bogota. Malnutrition is associated with perception of poor health, comorbidities, number of medications, and cognitive impairment.
