Interventions

  • Sit Less, Move More (SLMM) for pregnant women — BEHAVIORAL
    Health Coach sessions and SMS texts ramp up to goal ACOG opinion 804 pregnancy physical activity; wearable device activity tracker (Fitbit) for monitoring and self-regulation, exercise with a partner for support and accountability most days of the week.

Study Details

Pregnant women are more sedentary (sit, recline, lie down more) on average than non-pregnant women (more than 12 versus less than 8 waking sedentary hours/day). Sedentary behavior has been related to psychological distress, pregnancy weight gain, impaired sleep and very large size infants, while adequate physical activity has been found to improve mental health, decrease risk of high blood pressure in pregnancy and lower risk of preterm birth infants (less than 37 weeks gestation). Decreased sedentary behavior and increased physical activity may be crucial and neglected lifestyle behavior changes that can be promoted to reduce these and other maternal health and birth outcome problems among pregnant women.
