and 2004, one in five women aged 18-29 years of age and almost a quarter of those in their thirties and forties reported no physical activity in 2004 (Figure 2-15) (CDC, 2005). Similarly, barely half of women of childbearing age met the guideline in Healthy People 2010 for aerobic activity in 2005, although the prevalence has increased significantly since 2001 (Figure 2-16) (CDC, 2007).
According to other available data, in 2000, 15.8 percent of pregnant women met minimum physical activity recommendations (Evenson et al., 2004) and only 6 percent of pregnant women met recommendations for vigorous physical activity (Petersen et al., 2005). In these analyses, physical activity varied by maternal race/ethnicity, age, and education; there was some evidence that physical activity was lower among women who worked outside the home. In 2005, almost half of white, non-Hispanic U.S. women of all ages met the Healthy People 2010 objective for physical activity; only 36 percent of black, non-Hispanic women, 40 percent of Hispanic women, and 47 percent of other-race women did so (CDC, 2007). Physical activity increased with education, from 37 percent among women who did not
