Differences among exercisers and nonexercisers during pregnancy
Date:4/17/2009

were healthy, non-smokers between 23 and 39 years of age. The sample population includes women with various education levels, employed in and out of the home, and who live in the Kansas City metro area. Exercisers participated in moderate or vigorous aerobic activity at least 30 minutes three times per week throughout the pregnancy. Control mothers did not.

Results

There were no differences between groups based on maternal age, education levels, employment, number of children, fetal gender, and even maternal height. Although these groups were similar in many ways, there were significant differences between groups and trends as well:

  • Although the most common reason for not exercising during pregnancy is 'lack of time,' 85% of control women spent more than 1 hour at the TV or computer and 77% spent more than 1 hour read/writing/studying.
  • There was a trend for the exercisers to have slightly more sleep and reading time.
  • There was a trend for non-exercisers to have slightly more TV/computer time.
  • BMI and maternal pre-pregnancy weight was significantly lower in the exercisers. Additionally, women with more education had lower BMIs, in general for both groups.
  • For non-exercising pregnant women, employment was a factor in maternal weight and BMI, such that those who were worked outside of the home had lower BMIs.

Conclusion

The researchers theorize that pregnant mothers who exercise may manage their time more effectively than non-exercisers. Because exercisers sleep and read slightly more than non-exercisers and spend slightly less time on the computer, researchers conclude that exercisers are simply more likely to fit exercise into their day. Non-exercisers may suffer from a perception that they lack time to exercise, when they need to manage their time differently to fit more physical activity into their
