DURAN A, Samuel; ULLOA A, Alejandra  e  REYES G, Sussanne. Nutrient intake of Chilean older people according to body mass index. Rev. méd. Chile [online]. 2014, vol.142, n.12, pp.1594-1602. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872014001200013.

Background: An adequate consumption of micro and macro nutrients is essential to maintain an adequate health among older people. Aim: To compare the consumption of micro- and macronutrients in older people from three Chilean cities, according to their nutritional status. Material and 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.
