Abstract

The findings suggest that higher prenatal <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msub><mml:mrow><mml:mrow><mml:mi>PM</mml:mi></mml:mrow></mml:mrow><mml:mrow><mml:mrow><mml:mn>2.5</mml:mn></mml:mrow></mml:mrow></mml:msub></mml:mrow></mml:math> exposure, particularly in the second trimester, is associated with elevated early childhood blood pressure. This adverse association could be modified by pregnancy folate concentrations. https://doi.org/10.1289/EHP7486.
