Brief Summary

This pilot study will test the feasibility, acceptability, and efficacy of a remotely-delivered intervention for increasing daily physical activity levels and reducing sedentary behavior during pregnancy among women who are insufficiently active (i.e. reporting <150 minutes/week of moderate intensity activity and/or <7,000 steps/day). It is hypothesized that women will increase daily steps and decrease total sedentary time across the second trimester of pregnancy.

Detailed Description

Physical activity during pregnancy is safe for the mother and baby and has many health benefits; however, less than 25% of pregnant women meet the recommended physical activity guidelines. Data from the investigative team also indicates that high sedentary behavior across pregnancy trimesters is associated with an increased risk of hypertensive disorders of pregnancy and other adverse pregnancy outcomes, independent of physical activity level. There is a clear need to encourage physical activity participation while concurrently promoting a reduction in sedentary time during pregnancy.

This pilot study will test the feasibility, acceptability, and efficacy of a remotely-delivered intervention for increasing daily physical activity levels and reducing sedentary behavior during pregnancy among women who are insufficiently active (i.e. reporting <150 minutes/week of moderate intensity activity and/or <7,000 steps/day). We hypothesized that participants would increase daily steps and decrease total sedentary time over the course of the intensive intervention phase (second trimester, ~14 weeks). Further, we hypothesized that participants would maintain or have minimal changes in daily steps and total sedentary time from the end of the intensive intervention phase through the follow-up phase (third trimester, ~14 weeks).

Intervention Summary: Participants have 12 contacts with a health coach using a telehealth platform to provide ongoing support and discuss physical activity and sedentary behavior goals based on real-time data obtained from a Fitbit monitor. Intervention contacts will be weekly for the first month, bi-monthly in months 2-4, and monthly until delivery. Participants will also receive one text message between each intervention contact to reinforce content discussed in coaching sessions. Physical activity and sedentary time will be assessed objectively using an activPAL device for 7-days at baseline and at the end of the intensive intervention phase (second trimester, ~14 weeks).

Specific Aims:

Aim 1: To test the feasibility of a remotely-delivered intervention designed to increase physical activity levels and reduce sedentary behavior during pregnancy. Feasibility will be defined by: (1) recruitment and enrollment of at least 50% of eligible women who completed the screening form, (2) retention of 85% or more participants from baseline through delivery, (3) adherence if participants attended 75% or more of the health coaching sessions on average and wore and synced their Fitbit device on at least 75% of days from baseline through the end of the intervention.

Aim 2: To test the acceptability of a remotely-delivered intervention designed to increase physical activity levels and reduce sedentary behavior during pregnancy. Acceptability will be defined as at least 75% of the participants indicating they were satisfied or very satisfied with the program overall.

Aim 3: To test the preliminary efficacy of a remotely-delivered intervention designed to increase physical activity levels and reduce sedentary behavior during pregnancy. Efficacy will be determined using paired t-tests to assess activPAL-measured changes in physical activity (steps/day, stepping minutes/day, standing minutes/day) and sedentary behavior (sedentary minutes/day, total and in bouts of 30 and 60 minutes) from baseline through the end of the second trimester (intensive intervention phase). The intervention specifically aims to increase physical activity levels and reduce sedentary behavior from enrollment through the end of the second trimester of pregnancy (intensive intervention phase), and then will encourage participants to maintain activity levels based on their comfort level through the third trimester (follow-up phase).
