Physical Activity Intervention
Wellness Education
The behavioral physical activity (PA) intervention focuses on walking, or stepping in place when it is not possible to walk (e.g., stormy weather). The primary goal of the PA intervention is to achieve at least 30 minutes per day of walking/stepping in place. The secondary goal is to use a PA tracker (e.g., the Fitbit Charge 3 provided by the intervention) to log and review walking/stepping, and to accumulate at least 3,000 steps during their 30 minutes of walking/stepping each day.
The Wellness Education intervention will deliver information on mom and baby wellness that is unrelated to physical activity, diet, metabolism, or weight (e.g., immunizations during pregnancy and encouragement to immunize the baby on schedule, postpartum contraceptive options and developing a contraceptive plan, infant car seats & safety checks).
