铅中毒是一种可预防的环境疾病。儿童和发育中的胎儿尤其脆弱;即使是低血铅水平（BLL）也与学习和行为问题有关。我们评估了密克罗尼西亚联邦Chunk州儿童及其照顾者的BLL和铅暴露的风险因素。在20个随机选择的村庄中随机选择2-6岁的儿童。儿童和照顾者提供静脉血，照顾者提供有关铅暴露可能风险因素的信息。儿童的平均BLL为39 μ g/l，照顾者为16 μ g/l。BLL>= 100 μ g/l的儿童（上升）为22.9（95% CI：4.5-116.0）倍更可能有一个照顾者与升高的BLL，6.2（95% CI：1.4-27.3）倍更有可能生活在外岛，3.4（95% CI：1.7-6.9）倍，更有可能有一个家庭成员谁铅捕鱼重量比其他儿童，即使在控制年龄和性别。对于儿童来说，61%的BLL升高可归因于捕鱼重量。即使在控制了年龄和教育程度之后，BLL升高的照顾者生活在熔化电池的家庭中的可能性也是其他照顾者的5.9倍（95% CI：1.5-23.7）。对于护理人员，37%的BLL升高可归因于电池熔化。儿童及其照顾者的BLL升高的相关性表明了一种常见的环境暴露。融化电池制造钓鱼沉子是一个可预防的铅暴露源的儿童和他们的照顾者在大块。由爱思唯尔有限公司出版。
Lead poisoning is a preventable environmental disease. Children and developing fetuses are especially vulnerable; even low blood lead levels (BLLs) are linked with learning and behavioral problems. We assessed children's and their caregivers' BLLs and risk factors for lead exposure in Chunk State, Federated States of Micronesia. Children aged 2-6 years were randomly selected within 20 randomly selected villages. Children and caregivers provided venous blood, and caregivers offered information about possible risk factors for lead exposure. Mean BLLs were 39 mu g/l for children and 16 mu g/l for caregivers. Children with BLLs of >= 100 mu g/l (elevated) were 22.9 (95% CI: 4.5-116.0) times more likely to have a caregiver with an elevated BLL, 6.2 (95% CI: 1.4-27.3) times more likely to live on an outer island, and 3.4 (95% CI: 1.7-6.9) times more likely to have a family member who made lead fishing weights than did other children even after controlling for age and sex. For children, 61% of elevated BLLs could be attributed to making fishing weights. Caregivers with elevated BLLs were 5.9 (95% CI: 1.5-23.7) times more likely to live in a household that melted batteries than other caregivers even after controlling for age and education. For caregivers, 37% of the elevated BLLs could be attributed to melting batteries. The association of elevated BLLs in children and their caregiver suggests a common environmental exposure. Melting batteries to make fishing sinkers is a preventable source of lead exposure for children and their caregivers in Chunk. Published by Elsevier GmbH.
