Nutritional status of institutionalised elderly in Ecuador

Abstract:

The nutritional status of 111 elderly men and women aged 60 to 99 years in two institutions in the Ecuadorian Andes was evaluated using dietary, anthropometric and biochemical measurements. Mean daily energy intakes of men and women were 1720 and 1650 kcal, respectively (7.2 and 6.9 MJ), corresponding to 1.5 times the calculated basal metabolic rate (BMR). 6 % of subjects had intakes less than 1.2xBMR and 40 % less than 1.5xBMR. Body mass index (BMI) was below 20 kg/m2 in 21 % of subjects; 45 % were between 20 and 24. Only one subject had a BMI over 29. Intakes of protein, calcium, iron, riboflavin and vitamin C were satisfactory, in contrast to those of zinc, vitamin A, niacin and thiamin. Using sex- and altitude-specific cut-offs for hemoglobin, anemia was observed in 11 % of subjects. Nutritional status, evaluated using biochemical indicators, was satisfactory with respect toribo flavin, vitamin A, vitamin E and copper. 14 % of subjects had low serum zinc levels and 17 % had serum albumin values below 35 g/L. Low physical activity was associated with low energy intake and low serum albumin levels.
