• The authors investigated the effect of amalgam fillings and fish consumption on urine mercury level (UHg), in children aged 4–8 years old inclusive. Using a sample of 60 children, we found that children with amalgam fillings had significantly higher UHg levels than children without amalgams (geometric mean=1.412 μg Hg/g versus 0.436 μg Hg/g, respectively, P=0.0001). Subjects with reported higher fish consumption also had significantly higher UHgs ( P=0.004). Univariate analyses provide evidence of an association between elevated UHg level and young age ( P=0.009), short height ( P=0.024), and low weight ( P=0.049) in children with amalgam chewing surfaces. We also found a negative correlation between urine mercury and age (−0.378), height (−0.418), and weight (−0.391). A multiple logistic regression model shows that the presence of amalgam fillings leads to increased odds of high UHg in children (OR=47.18), even after adjusting for high fish consumption (OR=8.66) and height (OR=11.36).
