Popis: Lead poisoning in children is a major public health concern worldwide, especially in developing countries. We conducted a cross-sectional study on 403 children aged from 3 to 14 years living nearly zinc–lead mining areas in two provinces in Vietnam (Bac Kan and Thai Nguyen) from 06/2016 to 10/2016 to identify risk factors for lead contamination. Results. The proportion of children withblood lead levels BLLs≥10 μg/dL was 80.51% in Bac Kan and 50% in Thai Nguyen; the mean blood lead level for children was14.41±9.42 μg/dL. In linear regression analyses, the body mass index was negatively associated with elevated BLLs withr=−0.404,p<0.05(95% CI: -0.801, -0.006). In multivariable regression analysis, several risk factors were associated with lead contamination including male sex (aOR=2.44, 95% CI: 1.13-5.24,p=0.02), play areas in Bac Kan (aOR=2.3(1.02-5.17),p=0.04), proximity of children’s home of less than 2 kilometers from the mine (aOR=2.90(1.54-5.44),p=0.001), and inattentive symptoms in Thai Nguyen (aOR=7.85, 95% CI 3.49-17.69,p=0.001). Environmental factors, including lead concentrations in the soil and ambient air samples in both locations, are many times higher than Vietnamese standards.
