The MOTHER (Mobile Technologies to Help Enhancing Regular Physical Activity) Trial for Pregnant Women

Study Overview
=================
Brief Summary
-----------------
Obesity among women of childbearing age and excessive weight gain during pregnancy are prevalent and steadily increasing health care issues. Regular physical activity is recommended to maintain healthy weight gain for pregnant women, however, a majority of pregnant women are sedentary. The investigators proposed to conduct a pilot study to estimate the potential efficacy of a mobile phone based physical activity intervention in 30 physically inactive pregnant women.
