Analysis on Blood Lead Concentrations of 29 678 Children in Ningbo City, Zhejiang Province

  • 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& #177;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。

     

    Abstract: Objective 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.

    Methods 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.

    Results The average blood lead levels was (32.76& #177;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 differnce.

    Conclusion Lead poisonings occur more likely in boys than in girls. The blood lead level is decreased after year of 2012.
