In a large population-based study,
Evenson et al. collected data from 1,979 pregnant and 44,657 non-pregnant women and noted
that 65.6% of pregnant participants reported some physical activity in the last month, compared
to 73.2% of non-pregnant women [28]. However, based on the recommended 150 minutes
of moderate exercise per week, the observed prevalence was 15.8% vs. 26.1%, respectively
[28]. In an Irish cohort of healthy pregnant women, 21.5% followed the American College of
Obstetricians and Gynecologists (ACOG) recommendations [29]. In a British population, the
prevalence of pregnant women who engaged in exercise of moderate intensity for 3 hours per
week was higher, approximately 48% in the 18th and 32nd weeks of pregnancy [17].
