摘要
[目的]分析宁波市29 678例儿童血铅水平以及铅中毒情况,为防治铅中毒提供临床依据。[方法]采用微分电位溶出法检测血铅水平。将2011年1月—2014年6月在宁波市妇女儿童医院检验科检测血铅指标的29 678例患儿按性别分为男、女两组;按年龄分为婴儿组、幼儿组、学龄前组、学龄组、青春期组;按年份分为2011、2012、2013和2014年4组,并对检测结果进行统计学分析。[结果]29 678例儿童血铅水平为(32.76±29.07)mg/L,铅中毒率为0.56%(166/29 678)。男童血铅水平及铅中毒率均高于女童(P<0.05);在青春期前,血铅水平随年龄增长而升高(r=0.189,P<0.05),血铅中毒率在不同年龄组间差异无统计学意义;血铅均值水平从2012年开始逐年下降(r=0.132,P<0.01),铅中毒率有下降趋势,但差异无统计学意义。[结论]男童较女童更易发生铅中毒,2012年以后血铅水平呈下降趋势。
[ Objoctivo ] To provide clinic reference for preventing children from lead poisoning by studying the levels of lead and the conditions of lead poisonings in 29 678 children in Ningbo. [ Mothods ] The blood lead levels of 29 678 children visiting to the Ningbo Women & Children's Hospital from January 2011 to June 2014 were detected by using differential potentiometric stripping. The children were divided by gender (boy and girl), age (infant, toddler, preschool child, school-age child, and adolescence), or year of detection (2011, 2012, 2013, and 2014) to analyze the blood lead test results. [ Rosults ] The average blood lead levels was (32.76 ± 29.07)mg/L of the 29 678 children, and the rate of lead intoxication was 0.56% (166/29 678). The blood lead levels and lead intoxication rates in boys were higher than those in girls (P 〈 0.05). Except the adolescence group, the blood lead levels increased with age (r=0.189, P 〈 0.05), but the lead poisoning rate had no significant differences among different age groups (P〉0.05). The blood lead levels decreased over time since 2012 (r=-0.132, P〈0.01), and the lead poisoning rate showed an dereasing trend, but no significant differnee. [ Conclusion ] Lead poisonings occur more likely in boys than in girls. The blood lead level is decreased after year of 2012.
