目的：估计巴西老年人营养摄入不足的发生率。方法：本研究基于全国膳食调查的数据，该调查是 2008-2009 年家庭预算调查的一部分。所有 60 岁及以上的人均被纳入其中，共计 4,322 人。个人食物摄入量是从非连续两天的食物记录中获得的。每种营养素的习惯摄入量是通过国家癌症研究所的方法估算的，其中性别和地区作为协变量。使用 EAR 方法定义临界点，按性别和地区分层估计营养摄入不足的发生率。 结果：在两性中都观察到维生素 E、D 和 A、钙、镁和吡哆醇摄入不足的发生率很高 (> 50%)。在所有地区，维生素 E 摄入量均出现 100% 不足。除北部地区外，维生素 D 的摄入量几乎 100% 不足。在北部、东北部和中西部地区，维生素A摄入不足的比例高于70%。在评估的矿物质中，钙和镁在所有地区的摄入不足发生率最高（> 80%）。结论：本研究发现巴西老年人中被认为可预防慢性疾病的营养素摄入不足的发生率很高。
OBJECTIVE: To estimate the prevalence of inadequate nutrient intake in the Brazilian elderly.METHODS: This study was based on data from the National Dietary Survey, part of the Household Budget Survey 2008-2009. All individuals aged 60 and over, totaling 4,322 individuals, were included. Individual food intake was obtained from food records from two non-consecutive days. The habitual intake for each nutrient was estimated by the National Cancer Institute method, in which sex and region were included as covariates. The prevalence of inadequate nutrient intake was estimated stratified by sex and region using the EAR method to define cut-off points.RESULTS: A high prevalence of inadequate intake (> 50%) of vitamins E, D and A, calcium, magnesium and pyridoxine was observed for both sexes. In all regions, 100% inadequate vitamin E intake was observed. Vitamin D showed almost 100% inadequate intake except in the North region. The prevalence of inadequate vitamin A intake was higher than 70% in the North, Northeast, and Midwest regions. Among the minerals evaluated, calcium and magnesium showed the highest prevalence of inadequate intake (> 80%) in all regions.CONCLUSIONS: The present study found a high prevalence of inadequate intake of nutrients recognized as being protective against chronic diseases among the Brazilian elderly.
