Study Links Chemical Mixtures to Increased Childhood Obesity Risk
A new study published in *Environment International* has found a link between exposure to mixtures of hormone-disrupting chemicals during pregnancy and early childhood and an increased risk of obesity that persists into adolescence. The research, which followed 1,301 mother-child pairs from six European birth cohorts, examined prenatal and childhood exposure to 45 endocrine-disrupting chemicals (EDCs) across nine chemical classes. These classes included per- and polyfluoroalkyl substances (PFAS), phthalates, pesticides, polychlorinated biphenyls (PCBs), flame retardants, metals, parabens, and phenols, including bisphenol A (BPA) and triclosan. The study found that greater exposure to certain combinations of EDCs was associated with higher Body Mass Index (BMI), more body fat, and increased odds of being overweight, with about 28% of children being overweight or obese at age 8, rising to 30% by age 15.
