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。
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 wascollected 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 thatin women, while the levels of calcium, chrome and copper in men＇s serum are lower than those in women.
