title: [Nutrient intake of Chilean older people according to body mass index].
abstract: BACKGROUND
  An adequate consumption of micro and macro nutrients is essential to maintain an adequate health among older people.
  
  
  OBJECTIVE
  To compare the consumption of micro- and macronutrients in older people from three Chilean cities, according to their nutritional status.
  
  
  METHODS
  Body mass index (BMI) was assessed and a food consumption tendency survey was applied to 976 non-disabled older people, living in the community. Thinness was defined as a BMI < 23 kg/m².
  
  
  RESULTS
  Twenty percent of females and 17% of males had a BMI < 23 kg/m². Participants with a higher BMI had a greater intake of micro- and macronutrients. In females, micronutrient intake was adequate among those with higher BMI, although mean intake of calcium and vitamin B-12 were below recommendations. In males, iron, zinc, calcium, magnesium, vitamin A, vitamin B6, vitamin B12 and pantothenic acid intake were below recommendation.
  
  
  CONCLUSIONS
  Thin older adults, regardless of sex, had a lower intake of calories and micro- and macronutrients. Additionally, an overall low consumption of zinc, calcium, magnesium and vitamin B12 was detected.
