目的了解南平市延平区2~7岁儿童血中锌、铁、铜和钙元素缺乏情况,为制定儿童保健措施提供依据。方法用BH7100光谱分析仪,检测1 220名儿童静脉血的4种微量元素并进行分析。结果受检儿童血中锌、铁、铜和钙元素缺乏率分别为23.6%、23.2%、6.6%和4.4%,主要以锌、铁缺乏为主;各年龄组血锌、铁元素缺乏有统计学意义,且随年龄增大呈逐渐下降趋势;女童铁元素缺乏率(26.0%)高于男童(20.7%);农村儿童微量元素缺乏率(76.6%)高于城市儿童(46.0%),主要是锌、铁缺乏(农村、城市分别为30.2%、19.2%和34.2%、15.7%)。结论应加强营养知识的宣传,向儿童家长传输合理营养和平衡膳食的科学理念。对有明显微量元素缺乏的儿童,应在膳食中调整食品,严重缺乏者可用药物治疗,有关部门应积极开展儿童膳食调查及定量食谱的制定,为儿童合理膳食提供依据。
Objective To understand the deficiency of zinc, iron, copper and calcium in children aged 2 ~ 7 years old in Yanping District, Nanping City, and to provide basis for formulating child health care measures. Methods Using the BH7100 spectrometer, four trace elements in venous blood of 1 220 children were detected and analyzed. Results The deficient rates of zinc, iron, copper and calcium in the children were 23.6%, 23.2%, 6.6% and 4.4%, respectively, and the main ones were zinc and iron deficiency. There were statistics on the deficiency of zinc and iron in each age group (26.0%) in girls was higher than that in boys (20.7%). The rate of trace elements deficiency in rural children was 76.6%, higher than that in urban children (46.0%), Mainly zinc, iron deficiency (rural, cities were 30.2%, 19.2% and 34.2%, 15.7%). Conclusion The publicity of nutrition knowledge should be strengthened and the scientific concept of reasonable nutrition and balanced diet should be transmitted to parents of children. Children with obvious trace element deficiency should adjust their food in the diet, while those who are in severe deficit need medical treatment. The relevant departments should actively carry out the children’s dietary survey and the formulation of the quantitative recipes to provide the basis for a reasonable diet for children.
