The distribution and influencing factors on age, reproductive history and dietary habits in scalp hair of rural childbearing female in the county of XingHe, Inner Mongolia of China were studied. 21 mineral elements including essential and toxic elements (Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, Pb, Se, Si, Sn, Sr, Ti, V and Zn ) in scalp hair samples from 180 females of childbearing age were measured with inductively coupled plasma-atomic emission spectrometry (ICP-AES) and atomic fluorescence spectrometry (AFS), respectively. The results demonstrated that the content of the most mineral elements (B, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, Pb, Se, Si, Sn, Sr, Ti, V and Zn) existed in a descending order in the hair of young age group (18～29 years) to the elder age group (40～45 years), while elements of Ca, Mg, Mn and Pb were found to have the lowest content in the middle age group (30～39 years). Women having two children were more likely to have the lowest content of Ca, Mg, Mn, Mo, Ni, Pb, Sn, Sr and Zn due to the increased numbers of pregnancies, the statistically correlations had been proved among Ca, Pb and Sn. In addition, dietary habits also can affect the level of the mineral elements in hair, for example, consuming suancai food frequently can cause lower level of Zn, Fe, Cu, Mn, Sr, Mo and Pb, but higher Se, the frequent intake of meat resulted in increased content of Zn and Se. The individuals that declared intaking vegetables regularly had more Si in their hair. Also, daily intake of fruit leads to higher level of Mn, Ni and Ti. This study will provide basic and useful information when addressing reproductive and women health challenges in the rural areas where poor dietary habits are prevailing.
对中国内蒙古自治区兴和县农村育龄女性头皮头发中矿物质元素的分布及其与年龄、生育史和饮食习惯的关系进行了研究。采用电感耦合等离子体原子发射光谱法（ICP-AES）和原子荧光光谱法（AFS）分别测定了180名育龄女性头皮头发样本中包括必需元素和有毒元素（铝、硼、钡、钙、镉、钴、铬、铜、铁、镁、锰、钼、镍、铅、硒、硅、锡、锶、钛、钒和锌）在内的21种矿物质元素。结果表明，大多数矿物质元素（硼、镉、钴、铬、铜、铁、镁、锰、钼、镍、铅、硒、硅、锡、锶、钛、钒和锌）的含量在年轻年龄组（18～29岁）到年长年龄组（40～45岁）的头发中呈下降趋势，而钙、镁、锰和铅元素在中年年龄组（30～39岁）中含量最低。生育两个孩子的女性由于怀孕次数增加，更有可能使钙、镁、锰、钼、镍、铅、锡、锶和锌的含量最低，钙、铅和锡之间已证明存在统计学相关性。此外，饮食习惯也会影响头发中矿物质元素的水平，例如，经常食用酸菜会导致锌、铁、铜、锰、锶、钼和铅的水平降低，但硒水平升高，经常摄入肉类会导致锌和硒含量增加。宣称经常摄入蔬菜的个体头发中的硅含量更高。此外，每日摄入水果会导致锰、镍和钛的水平升高。本研究将为应对饮食习惯不良的农村地区的生殖和妇女健康挑战提供基础且有用的信息。
