title: Nutritional assessment and factors associated to malnutrition in older adults: a cross-sectional study in Bogotá, Colombia.
abstract: OBJECTIVE
  To determine the nutritional status and factors associated to malnutrition in older adults.
  
  
  METHODS
  Data come from the SABE Bogotá study (Health, Well-Being, and Aging), a cross-sectional survey conducted in Bogotá, 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).
  
  
  CONCLUSIONS
  The MNA is useful to evaluate factors associated with malnutrition among older adults in Bogotá. Malnutrition is associated with perception of poor health, comorbidities, number of medications, and cognitive impairment.
