Adherence to the Planetary Health Diet Index and Fetal Body Composition

Is periconceptional and early pregnancy adherence to the Planetary Health Diet (PHD) associated with fetal growth?In this cohort study of 1464 pregnant women, high relative to low maternal adherence to the PHD was associated with larger fetal fractional fat arm volumes in the second trimester and larger fetal weight and abdominal measures in the third trimester.In this cohort study, adherence to the PHD during periconceptional and early pregnancy was associated with larger in utero fetal adiposity measures in the second and third trimester, suggesting potential implications for offspring metabolic health.
