Although lead recycling activities are a known risk factor for elevated blood levels in South East Asia, little is known regarding the prevalence of and risk factors for elevated blood lead levels (BLL) among the general pediatric population in Vietnam. This study is a cross-sectional evaluation of 311 children from Children's Hospital #2 in Ho Chi Minh City, Vietnam. Capillary blood lead testing was performed using the LeadCare II. Mean BLLs were 4.97 μg/dL (Standard Deviation (SD) 5.50), with 7% of the participants having levels greater than 10 μg/dL. Living in Bing Duong province (OR 2.7, 95% CI 1.4-5.6.1) or the Dong Nai province (OR 2.3, 95% CI 1.0-5.1) and having an age greater than 12 months (OR 6.0, 95% CI 3.1-11.8) were associated with higher BLLs. The prevalence of elevated BLLs in Vietnam is consistent with other SE Asian countries. Mean BLLs in Ho Chi Minh City are markedly less than those seen in a separate study of children living near lead recycling activities. Additional evaluation is necessary to better detail potential risk factors if screening is to be implemented within Vietnam.
尽管铅回收活动是东南亚血铅水平升高的已知危险因素，但对于越南普通儿科人群血铅水平升高（BLL）的患病率和危险因素知之甚少。本研究是对越南胡志明市儿童医院 2 号的 311 名儿童进行的横断面评估。使用 LeadCare II 进行毛细血管血铅检测。平均 BLL 为 4.97μg/dL（标准差（SD）为 5.50），7%的参与者血铅水平大于 10μg/dL。居住在平当省（OR 2.7，95%CI 1.4-5.6）或同奈省（OR 2.3，95%CI 1.0-5.1）以及年龄大于 12 个月（OR 6.0，95%CI 3.1-11.8）与较高的 BLL 相关。越南 BLL 升高的患病率与其他东南亚国家一致。胡志明市的平均 BLL 明显低于另一项对居住在铅回收活动附近的儿童进行的研究。如果要在越南进行筛查，需要进一步评估以更详细地了解潜在的危险因素。
