目的:调查我区2010年至2011年7个月至5岁正常儿童微量元素铁减少的患病率,并对他们的患病原因进行分析。方法:以7个月至5岁的正常体检儿童为调查对象,检测其末梢血微量元素铁的含量,按年龄组进行统计学分析并调查原因。结果:7月至5岁儿童体内微量元素铁的减少率为2.38%,各年龄组的元素铁减少率分别为:7个月—12个月为7.25%;1岁—3岁为1.97%;3岁—5岁为0.85%。不同年龄组的元素铁减少率由高到低依次为7个月-12个月,1岁—3岁,3岁—5岁,各个年龄组间的差异有显著意义(P<0.01)。调查病因,90.14%为偏食厌食。结论:婴儿微量元素铁的减少率最高,主要原因为摄入不足。
OBJECTIVE: To investigate the prevalence of iron deficiency in normal children in our district from 2010 to 2011 and from the age of 5 to 5 years old, and to analyze their causes. Methods: The normal children from 7 months to 5 years old were selected as subjects to detect the content of trace element iron in peripheral blood. The age group was used for statistical analysis and the reason was investigated. Results: The decrease rate of trace iron in children from July to 5 years old was 2.38%. The reduction rate of elemental iron in each age group was 7.25% in 7 months to 12 months and 1.97% in 1 year to 3 years. 3 years old -5 years old is 0.85%. The iron reduction rates of different age groups from high to low were 7 months -12 months, 1-year-3 year old, 3-year-5 year old, with significant difference among all age groups (P <0.01). The etiology of the survey, 90.14% partial eclipse anorexia. Conclusion: The highest rate of decrease of trace elements iron in infants is mainly due to inadequate intake.
