To compare blood lead levels (BLLs) among children residing in public and private housing in New York City and examine the implications for lead identification and remediation policies. We examined electronic medical records for BLLs among 4693 children receiving care at a multisite Federally Qualified Health Center during 2003 to 2017. We plotted home addresses against city housing data to assess BLL differences between children living in public housing and private housing. Only 0.25% of children residing in public housing had BLLs exceeding the upper reference limit of 5 micrograms per deciliter, as compared with 2.76% of children residing in private housing. After adjustment for age, gender, and race/ethnicity, public housing was associated with 92% lower odds of having a BLL of 5 micrograms per deciliter or above (odds ratio [OR] = 0.08; 95% confidence interval [CI] = 0.02, 0.33; = .001). Decreases in BLLs were observed in both public and private housing over time. Children living in public housing in New York City were significantly less likely to have elevated BLLs than were children living in private housing. Decreases in BLLs over time were likely a result of lead reduction legislation.
比较居住在纽约市公营和私营房屋的儿童的血铅水平 (BLL)，并探讨其对铅识别和修复政策的影响。我们检查了 2003 年至 2017 年期间在一个多地点联邦合格医疗中心接受治疗的 4693 名儿童的电子病历中的 BLL。我们将家庭住址与城市住房数据进行对比，以评估居住在公营住房和私营住房的儿童之间的 BLL 差异。只有 0.25%居住在公营住房的儿童的 BLL 超过每分升 5 微克的上限参考值，而居住在私营住房的儿童这一比例为 2.76%。调整年龄、性别和种族/民族因素后，公营住房与 BLL 为 5 微克/分升或以上的几率降低 92%相关（比值比 [OR] = 0.08；95%置信区间 [CI] = 0.02，0.33；= 0.001）。无论在公营住房还是私营住房，BLL 随时间呈下降趋势。居住在纽约市公营住房的儿童 BLL 升高的可能性明显低于居住在私营住房的儿童。BLL 随时间的降低可能是铅减排立法的结果。
