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 1.2 x BMR and 40% less than 1.5 x BMR. 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 cutoffs for hemoglobin, anemia was observed in 11% of subjects. Nutritional status, evaluated using biochemical indicators, was satisfactory with respect to riboflavin, 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.
通过饮食、人体测量和生化指标测量，对厄瓜多尔安第斯山脉两个机构中111名年龄在60至99岁之间的老年男性和女性的营养状况进行了评估。男性和女性的平均每日能量摄入量分别为1720千卡和1650千卡（7.2兆焦和6.9兆焦），相当于计算出的基础代谢率（BMR）的1.5倍。6%的受试者摄入量低于1.2xBMR，40%低于1.5xBMR。21%的受试者体重指数（BMI）低于20kg/m²；45%在20至24之间。只有一名受试者的BMI超过29。蛋白质、钙、铁、核黄素和维生素C的摄入量令人满意，锌、维生素A、烟酸和硫胺素的摄入量则相反。使用性别和海拔特定的血红蛋白临界值，11%的受试者出现贫血。使用生化指标评估的营养状况在核黄素、维生素A、维生素E和铜方面令人满意。14%的受试者血清锌水平较低，17%的受试者血清白蛋白值低于35g/L。低体力活动与低能量摄入和低血清白蛋白水平相关。
