Sit Less, Move More program to increase physical activity during pregnancy
Effectiveness of Interventions to Promote Physical Activity During Pregnancy
NA · University of Central Florida · NCT07223112
This program will try a Fitbit-based Sit Less, Move More plan to help pregnant women under 12 weeks gestation who do less than 150 minutes of activity per week sit less and move more.

What this trial studies
Using a behavioral clinical trial design, researchers will recruit 60 pregnant women with singleton pregnancies at 8–12 weeks gestation from prenatal clinics. Participants will wear an ActiGraph tracker for two weeks to measure baseline sedentary behavior and activity, then receive a Fitbit, a sedentary behavior and physical activity prescription, and coaching via text or email to prompt habit changes. The intervention emphasizes breaking up sitting time, increasing daily movement, and using an activity partner for support. Outcomes include changes in sedentary time, weekly physical activity minutes, and maternal and infant health measures.
Who should consider this trial
Good fit: Ideal candidates are English-speaking women aged 18–45 with a singleton pregnancy at 8–12 weeks gestation who currently do less than 150 minutes/week of moderate activity and can use a smartphone or computer for Fitbit data and commit to an activity partner.
Not a fit: Women with medical restrictions on activity (for example placenta previa), those with multiple gestations, or women already meeting activity guidelines are unlikely to benefit from this program.
Why it matters
Potential benefit: If successful, the program could reduce sedentary time and increase activity during pregnancy, potentially improving maternal mental health, weight gain, blood pressure, sleep, and infant outcomes.
How similar studies have performed: Wearable-based activity programs have shown promise for increasing physical activity in pregnant and nonpregnant adults, but focused sedentary-behavior interventions in pregnant women are relatively novel.
Eligibility criteria
Show full inclusion / exclusion criteria
Eligibility Criteria * 18 to 45 years old * speak English * 8 to 12 weeks pregnant (gestation) * singleton pregnancy (no twins or more) * self-report less than 150 minutes/week of moderate-intensity physical activity * have or are willing to identify a physical activity partner * have a cell phone with the capacity for Fitbit application (app.); secure transmission of Fitbit data; receive coaching text messages or, if not, a computer they can use to synch the fitbit, send data, and receive email messages in lieu of texts. Exclusion Criteria • Women with physical activity restrictions (e.g., placenta previa) that prevent them from completing ACOG recommended pregnancy physical activity
