Randomized Clinical Trial to Increase Physical Activity After a a Hypertensive Pregnancy (STEPUP)

December 11, 2020 updated by: University of Pennsylvania

A Randomized, Clinical Trial Evaluating Methods to Increase Physical Activity After a Pregnancy Complicated by a Hypertensive Disorder

STEPUP is a 12-week randomized clinical trial among 126 postpartum women with pregnancies complicated by hypertensive disorders. Participants will be randomized to a control arm and receive a Fitbit or an intervention arm. The intervention arm will receive a Fitbit and set a step count goal, receive daily feedback via text about whether they reached their goal, and will be placed in virtual teams with other participants where they can win points for their team if they meet their daily goals. The main study outcomes will be increase in mean step count and change in psychosocial survey measures.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Women with hypertensive disorders of pregnancy, such as preeclampsia and gestational hypertension, are at elevated risk of developing hypertension, diabetes, heart failure, and premature atherosclerotic cardiovascular disease. Current guidelines recommend intensive lifestyle modification for women with a history of hypertensive disorders in pregnancy in order to reduce the risk of developing cardiometabolic risk factors or overt CV disease. However, limited research exists to guide how to implement lifestyle modification for this population. The postpartum period poses unique challenges to adopting a healthy lifestyle. Remote interventions using mobile technology may be particularly effective. Social incentives designed using insights from behavioral economics have been demonstrated to motivate health behavior change, such as increasing physical activity. The objective of this study is to use a randomized clinical trial to test the effectiveness of a 12-week team-based, mobile health interventions using wearable devices and social incentives to increase physical activity in the postpartum period.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
128

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Control
Individual participants will use a wearable device to monitor daily step counts, set a step goal, and receive automated daily feedback on step goal attainment.
Experimental: Social incentives-based program
Individual participants will use a wearable device to monitor daily step counts, set a step goal, and receive automated daily feedback on step goal attainment. Participants will be placed on a team of 3 randomly assigned participants and receive the social incentives intervention.
Behavioral: Social incentives-based program
Individual participants will use a wearable device to monitor daily step counts, set a step goal, and receive automated daily feedback on step goal attainment. Participants will be placed on a team of 3 randomly assigned participants and receive the social incentives intervention.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
