The Project Wellness Pilot Feasibility Randomized Controlled Trial

February 9, 2024 updated by: The University of Tennessee, Knoxville

Project Wellness: A Pilot Feasibility Randomized Controlled Trial

This pilot feasibility randomized controlled trial will be conducted among women at risk for or diagnosed with gestational diabetes (GDM) at the University of Tennessee Medical Center Knoxville (UTMC). The trial will be called Project Wellness. It will compare a physical activity (behavior change) intervention (i.e., walking/stepping in place) versus a general wellness intervention (e.g., health education focusing on immunizations, contraceptive options following delivery, etc.) on physical activity levels, maternal glycemic profile in the third trimester, and infant size and anthropometric measurements soon after birth (i.e., weight, length, circumference, skinfolds). It is hypothesized that the physical activity intervention will increase physical activity levels, and improve maternal glycemic profile and infant anthropometric measures at birth. It is also hypothesized that maternal glycemic profile in the third trimester will be associated with infant anthropometric measurements at birth.

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

Participants will also be followed through 12 months postpartum: Maternal weight and device-based and self-reported measures of physical activity will be assessed at 3, 6, 9 and 12 months postpartum, as well as the same infant size and anthropometric measurements assessed soon after delivery.

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.

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

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.
Experimental: Physical Activity Intervention
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.
Behavioral: Physical Activity Intervention
Motivational interviewing techniques helped participants set reasonable, specific, and achievable individual goals at each session: a duration (i.e., minutes) and frequency (i.e., days of the week) of walking or stepping, and potentially, a step count (i.e., a proxy for intensity). Individual goals often differed from the program goal in an effort to meet the participants 'where they are'.
Other Names:
  • Step Up Program
Active Comparator: Wellness Education
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).
Other: Wellness Education
The following topics were addressed: postpartum contraception, maternal immunizations, infant immunizations, car seat safety and planning for your hospital stay, and safe sleep and skin to skin. No information on PA was provided to the control group (i.e., neither encouragement for PA nor instructions to limit PA).

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.
Outcome Measure
Measure Description
Time Frame
Change in Self-reported Physical Activity (Assessed by Pregnancy Physical Activity Questionnaire) From Baseline to Follow-up
Time Frame: approximately 6 weeks

Change in self-reported moderate to vigorous intensity walking or running activity within the sports & exercise domain, as assessed by Pregnancy Physical Activity Questionnaire (i.e., measure at follow-up study visit minus the measure at baseline study visit).

approximately 6 weeks
Change in Physical Activity Assessed by ActiGraph Monitoring Device From Baseline to Follow-up
Time Frame: approximately 6 weeks

Change in minutes per day of walk/run activity, as assessed by ActiGraph monitoring device (i.e., measure at follow-up study visit minus the measure at baseline study visit).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Neonatal Subscapular Skinfolds
Time Frame: Within 5 days of birth
Neonatal Subscapular Skinfolds (i.e., caliper measurement to assess neonatal body composition)
Within 5 days of birth
Birthweight-for-gestational-age Z-score
Time Frame: Within 5 days of birth

Birthweight-for-gestational-age Z-score based on the sex- and gestational-age-specific birth-weight distributions of the 2017 U.S. Natality files.

Z-scores more extreme than -1.645 and +1.645 indicate birthweight-for-gestational-age-and-sex at <10th and >90th percentiles, respectively, and thus indicate increased risks for adverse health outcomes (as the relationship is U-shaped). A Z-score of 0 represents birthweight-for-gestational-age-and-sex at the 50th percentile.
