摘要: 摘要: 目的 了解天津市老年人 8 种健康相关的矿物质元素营养水平, 为科学合理指导老年人改善膳食结构提供依据。方法 采集 714 例社区老年人静脉血, 用电感耦合等离子体-质谱仪 (ICP-MS) 对血清矿物质进行分析测定。结果 血清矿物质中存在 1 种或 1 种以上元素缺乏的人高达 92.7 %, 其中 Zn 缺乏最严重, 其次是 Mn, 其余依次为 Mg、 Cr、 Fe、 Ca、 Cu、 Se, 分别占总人群的 79.3%、 73.4%、 58.5%、 42.4%、 39.8%、 23.0%、 1.5%、 0.6%。此外, 血清矿物质水平存在性别差异, 其中血清 Fe 男性高于女性, 而血清 Ca、 Cr、 Cu 低于女性。结论 天津市老年人血清矿物质水平普遍低下, 提示在日常生活中应注意相关元素的摄取, 积极改进膳食结构。

Abstract: Abstract: Objective To investigate the levels of 8 minerals that are related to human health in serum of elderly popu⁃ lation in Tianjin and to provide evidence based guidance for scientifical and rational dietary. Methods Venous blood was collected from 714 elderly people and the levels of 8 minerals were examined by inductively coupled plasma - mass spec⁃ trometry (ICP-MS). Results The percentage of the elderly people who are short of at least one mineral was up to 92.7%. The percentages of deficiency in serum zinc, manganese, magnesium, chrome, iron, calcium, copper, selenium are 79.3 %, 73.4%, 58.5%, 42.4%, 39.8%, 23.0%, 1.5% and 0.6% respectively . The level of Ferrum in men’ s serum is higher than that in women, while the levels of calcium, chrome and copper in men’ s serum are lower than those in women. Conclusion The level of the minerals is generally low in the elderly population from Tianjin and ways were needed in improving dietary.
