Abstract:

Mercury (Hg) is a toxic substance, and fish consumption is one of the main sources of exposure for the population. This article aims to evaluate the association between exposure to Hg in children and adolescentssix riverside communities in the Brazilian Amazon and anemia. Secondary data analysiscross-sectional studies, including 1318 individuals, divided into two groups according to gold mining exposure (group A under the influence and group B without it). Multivariate analysis methods were performed to assess the association between exposure to Hg (hair Hg) and anemia, stratifying by groups. Three hundred forty-eight anemia cases were observed (27.1%), with 206group B and 142 out of group A. There was a difference in the median of Hg levels between groups (A=12.8µg/g and B=4.3µg/g, p=0.01). An association was observed between hair Hg levels ≥ 6.0 µg/g and anemia (OR=1.38; 95%CI=1.02-1.87), a fact that was magnified for group A, when stratification was performed (OR=2.23; 95%CI=1.28-3.90). This study showed high Hg levels, especially in group A and this substance might be a possible risk factor for anemia. Also, geographical areas seemed to modify this effect, pointing to other factors\' influence, which should be better evaluated.
