Discussion This study characterized urinary fluoride levels during the first and third trimesters of pregnancy among a cohort of predominately Hispanic pregnant women residing in urban LA. MUFsg levels observed in MADRES (trimester 1 mean = 0.81 mg/L; trimester 3 mean = 0.92 mg/L) were higher than those reported in one other US study, but comparable to those observed among pregnant women in Mexico and Canada for which higher levels have been associated with poorer neurodevelopmental out

2.3.1. Children's drawing tasks A total of 68 (37 males and 31 females) from the 74 children were enrolled and asked to participate in three drawing tasks of common objects that children readily encounter or experience in the study area, though their reproduction varies in complexity: a house, a person, and a donkey. They were provided with a pencil, rubber eraser, drawing pad, table, chair and allowed as much time to draw as they needed to complete their drawings, but no instruction or suppo

Fluoride exposure from the Odense Child Cohort (OCC) While the addition of fluoride to drinking water is not legal in Denmark, elevated fluoride concentrations up to 1.5 mg/l naturally occur in groundwater in parts of the country,13 and some types of tea, especially black tea, constitute an additional source of exposure.14 In Odense municipality, the fluoride concentration in drinking water is rather low, i.e. 0.2–0.3 mg/l.13 Given the retention in and continuous mobilization from calcified t
