We hypothesized that exercise during pregnancy and maternal BMI will be significant predictors of neonatal size. This hypothesis was tested by analyzing maternal and neonatal measurements. Women were exercise trained throughout pregnancy for 20 wks at moderate intensity for 150 min/wk. Maternal pre‐pregnancy BMI was self‐reported; and lipids were measured before and after exercise intervention. Fetal (36 wk) weight was acquired via ultrasound and neonatal measures were acquired via birth records. Data from 36 uncomplicated pregnancies (27 exercise, 9 control) were analyzed. Although exercise is not a significant predictor of neonatal size, exercise intervention changed maternal lipid levels. We found that a significant predictor of neonatal BMI is maternal LDL levels after exercise intervention training. A significant predictor of neonatal ponderal index is maternal triglycerides and LDL levels after exercise intervention training. Surprisingly, we have found exercise during pregnancy only indirectly influences neonatal measures by changing maternal lipid levels. These results suggest maternal lipids influence neonatal size, but exercise during pregnancy can help regulate this influence. These data further support the benefits of exercise during pregnancy on positive neonatal outcomes. Support or Funding Information ECU, 15GRNT24470029
