New Studies Suggest Newborns are Healthier if Mom 'Moderately' Exercises during Pregnancy

GREENVILLE, N.C., Feb. 23, 2021 /PRNewswire/ -- Moderate exercise during pregnancy, such as walking on a treadmill, may lead to healthier infants according to a new study included in a special issue of Birth Defects Research. The journal is published by the Society for Birth Defects Research and Prevention in partnership with John Wiley & Sons.

The study by McDonald, et al., didn't rely on self-reporting, which made the research especially reliable, according to Michiko Watanabe, PhD, co-editor of the special Birth Defects Research issue and professor at Case Western Reserve University School of Medicine. "The North Carolina team supervised a group of pregnant women during about 150 minutes of exercise per week," she said. The 1-month-olds born to the women had lower body fat percentages compared to the control group, which is associated with a lower risk for obesity later in life. "Earlier studies primarily look at the birth weight of babies. However, this study indicated exercise during pregnancy may continue to have a positive effect as babies grow older."

Other significant findings unveiled in the issue include those by Nagpal et al. that suggest exercise may help women before and during pregnancy who are struggling with substance use disorders. In addition, Ruben Barakat, PhD outlines a research-based exercise program modified for pregnant women that protects them from strains.
