出生缺陷是全世界面临的重要公共卫生问题,我国是出生缺陷的高发国家。引起出生缺陷的原因很多,微量元素在体内的消长情况也是导致出生缺陷的重要原因。很多研究表明:必需元素锌、硒、钙、铁、铜、镁缺乏特别是锌、硒缺乏,铁、钒摄入过高,以及非必需元素铅、汞、砷暴露都是引发出生缺陷的重要原因。机体内所有的元素都存在直接或间接的联系,彼此相互影响,提倡均衡膳食,适量摄入各种必需元素并注意彼此间的平衡,同时有效避免各种非必需元素的接触,才可以有效地减少出生缺陷的发生。
Birth defects are an important public health problem facing the world and our country is a high incidence of birth defects. Many causes of birth defects, the growth and decline of trace elements in the body is also an important cause of birth defects. Many studies have shown that lack of essential elements such as zinc, selenium, calcium, iron, copper and magnesium, especially zinc, selenium deficiency, excessive intake of iron and vanadium, and lead, mercury and arsenic, which are not essential elements, are all important factors in triggering birth defects the reason. All the elements of the body are directly or indirectly related to each other, to promote a balanced diet, adequate intake of various essential elements and pay attention to each other’s balance, while effectively avoiding the contact of various non-essential elements can effectively Reduce the incidence of birth defects.
