Jiang, Qi; Li, Qin – New Directions for Child and Adolescent Development, 2022
The association of overweight/obesity, and central obesity with thiocyanate (SCN), perchlorate (CIO), and nitrate (NO) in childhood and adolescence is unclear. Therefore, this study aimed to explore this association in 4447 participants comprising children and adolescents (aged 6-19 years) using data from the United States National Health and…

Betanzos-Robledo, Larissa; Téllez-Rojo, Martha M.; Lamadrid-Figueroa, Hector; Roldan-Valadez, Ernesto; Peterson, Karen E.; Jansen, Erica C.; Basu, Nil; Cantoral, Alejandra – New Directions for Child and Adolescent Development, 2022
Introduction: Heavy metals such as Lead (Pb) and Mercury (Hg) can affect adipose tissue mass and function. Considering the high prevalence of exposure to heavy metals and obesity in Mexico, we aim to examine if exposure to Pb and Hg in adolescence can modify how fat is accumulated in early adulthood. Methods: This study included 100 participants…

Schildroth, Samantha; Friedman, Alexa; Bauer, Julia Anglen; Claus Henn, Birgit – New Directions for Child and Adolescent Development, 2022
Iron is needed for normal development in adolescence. Exposure to individual environmental metals (e.g., lead) has been associated with altered iron status in adolescence, but little is known about the cumulative associations of multiple metals with Fe status. We used data from the 2017-2018 National Health and Nutrition Examination Survey…

Bastien, Kevin; Muckle, Gina; Ayotte, Pierre; Courtemanche, Yohann; Dodge, Neil C.; Jacobson, Joseph L.; Jacobson, Sandra W.; Saint-Amour, Dave – New Directions for Child and Adolescent Development, 2022
Inuit communities in Northern Quebec (Canada) are exposed to environmental contaminants, particularly to mercury, lead and polychlorinated biphenyls (PCBs). Previous studies reported adverse associations between these neurotoxicants and memory performance. Here we aimed to determine the associations of pre- and postnatal exposures to mercury, lead…

Merced-Nieves, Francheska M.; Chelonis, John; Pantic, Ivan; Schnass, Lourdes; Téllez-Rojo, Martha M.; Braun, Joseph M.; Paule, Merle G.; Wright, Rosalind J.; Wright, Robert O.; Curtin, Paul – New Directions for Child and Adolescent Development, 2022
Children are exposed to many trace elements throughout their development. Given their ubiquity and potential to have effects on children's neurodevelopment, these exposures are a public health concern. This study sought to identify trace element mixture-associated deficits in learning behavior using operant testing in a prospective cohort. We…

Miller, Alison L. – New Directions for Child and Adolescent Development, 2022
Child environmental health (CEH) science has identified numerous effects of early life exposures to common, ubiquitous environmental toxicants. CEH scientists have documented the costs not only to individual children but also to population-level health effects of such exposures. Importantly, such risks are unequally distributed in the population,…

Ugarte, Elisa; Johnson, Lisa E.; Robins, Richard W.; Guyer, Amanda E.; Hastings, Paul D. – New Directions for Child and Adolescent Development, 2022
The experience of poverty embodies complex, multidimensional stressors that may adversely affect physiological and psychological domains of functioning. Compounded by racial/ethnic discrimination, the financial aspect of family poverty typically coincides with additional social and physical environmental risks such as pollution exposure, housing…
