We investigated whether foreign birthplace and residence were associated with an increased risk of childhood lead poisoning.
We conducted a matched case-control study among New York City children (mean age=3 years) tested for lead poisoning in 2002 (n=203 pairs). Children were matched on age, date of test, and residential area. Blood lead and housing data were supplemented by a telephone survey administered to parents or guardians. Conditional logistic regression analysis was used to examine the relationship of lead poisoning status to foreign birthplace and time elapsed since most recent foreign residence after adjustment for housing and behavioral risk factors.
Both foreign birthplace and time since most recent foreign residence had strong adjusted associations with lead poisoning status, with children who had lived in a foreign country less than 6 months before their blood test showing a particularly elevated risk of lead poisoning relative to US-born children with no foreign residential history before their blood test (odds ratio [OR]=10.9; 95% confidence interval [CI]=3.3, 36.5).
Our findings demonstrate an increased risk of lead poisoning among immigrant children.
我们调查了出生地为国外以及在国外居住是否与儿童铅中毒风险增加有关。
我们在2002年接受铅中毒检测的纽约市儿童（平均年龄 = 3岁）中开展了一项匹配病例对照研究（n = 203对）。儿童按照年龄、检测日期和居住地区进行匹配。通过对父母或监护人进行电话调查补充血铅和住房数据。在对住房和行为风险因素进行调整后，使用条件逻辑回归分析来检验铅中毒状况与出生地为国外以及自最近一次国外居住以来所经过时间之间的关系。
出生地为国外以及自最近一次国外居住以来所经过的时间与铅中毒状况均有很强的校正关联，在血液检测前在国外居住不到6个月的儿童相对于血液检测前无国外居住史的美国出生儿童，显示出特别高的铅中毒风险（优势比[OR]=10.9；95%置信区间[CI]=3.3, 36.5）。
我们的研究结果表明移民儿童铅中毒风险增加。
