Poly- and perfluoroalkyl substances (PFAS) in the first 1000 days reduce linear growth, lean body mass and bone mineral density at age 3 years

Higher plasma PFAS levels in 'the first 1000 days' of life were negatively associated with height, LBM and BMD SDS at age 3 years, while exclusive breastfeeding during the first 3 months of life was positively associated with these outcomes. This suggest that early life plasma PFAS levels could jeopardize breastfeeding's known health benefits, which warrants further research.
