Abstract

Abstract Objective: To investigate whether inadequate intake of micronutrients, as defined by the Institute of Medicine’s (IOM) Recommended Dietary Allowance (RDA) according to gender, is associated with lower working memory performance in healthy seniors. Method: 601 female and 530 male seniors (≥60 years) in the National Health and Nutrition Examination Survey (NHANES) were included. Analyses of the association between RDA micronutrient reference levels and having a memory performance score in the lowest quartile were stratified by gender. Logistic regression was used to estimate unadjusted and adjusted odds ratios for having a memory performance score in the lowest quartile for individuals with inadequate RDA levels compared to adequate RDA levels. Results: Over half of participants had inadequate intake of vitamin C, choline, and zinc. Men who had less than the RDA of choline from their food were more likely to be in the lowest memory performance quartile, while women who with inadequate B2 were more likely to be in the lowest quartile. Discussion: Inadequate intake of micronutrients was significantly associated with lower working memory performance.

健康老年人的工作记忆与微量营养素摄入不足

摘要目的:探讨美国医学研究所(IOM)推荐膳食量(RDA)中按性别定义的微量营养素摄入不足是否与健康老年人工作记忆表现下降有关。方法:纳入全国健康与营养调查(NHANES)老年人601名女性和530名男性(≥60岁)。RDA微量营养素参考水平与最低四分位数的记忆表现评分之间的关联分析按性别分层。使用逻辑回归来估计RDA水平不足的个体与RDA水平充足的个体在最低四分位数上的记忆表现得分的未调整和调整的比值比。结果:超过一半的参与者维生素C、胆碱和锌的摄入量不足。从食物中摄取少于每日推荐摄入量的胆碱的男性更有可能处于记忆力最差的四分之一，而B2不足的女性更有可能处于记忆力最差的四分之一。讨论:微量营养素摄入不足与较低的工作记忆表现显著相关。

期刊介绍： The Journal of Nutrition in Gerontology and Geriatrics publishes original research studies that are directly relevant to clinical and community nutrition issues that affect older adults. Epidemiologic and community-based studies are suitable for JNE, as are well-controlled clinical trials of preventive and therapeutic nutritional interventions. The Journal of Nutrition in Gerontology and Geriatrics invites papers on a broad array of topics in the nutrition and aging field, including but not limited to studies of: preventive nutrition, nutritional interventions for chronic disease, aging effects on nutritional requirements, nutritional status and dietary intake behaviors, nutritional frailty and functional status, usefulness of supplements, programmatic interventions, transitions in care and long term care, and community nutrition issues.
