About this study

Official title: Targeted Lifestyle Change (TLC) Group Prenatal Care for Obese Women at High Risk for Gestational Diabetes: a Randomized Controlled Trial

To conduct a randomized trial to determine the effect of Targeted Lifestyle Change Group Prenatal Care (TLC) on maternal and neonatal outcomes in women at high risk for developing gestational diabetes mellitus (GDM).

Read the detailed description

Long term, the investigator aims to test the central hypothesis that those in TLC will have better maternal and neonatal outcomes than those in TC. The objective is to conduct a randomized trial to determine the effect of TLC group prenatal care on birthweight and neonatal body composition, maternal healthy lifestyle and diabetes-related outcomes, delivery and neonatal outcomes, and psychosocial stress and depression.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TLC Group Prenatal CareBehavioural

    TLC will start in the late first trimester or early second trimester and run for ~6-10 sessions. Groups of 2-10 consented women, with two or more GDM risk factors, will meet under the supervision of an obstetric provider (nurse practitioner or MD) and co-facilitator (health educator, nutritionist, or nurse) for two-hour sessions. A major focus of TLC will be education, and much of each visit will be spent on pregnancy, exercise/nutrition education, and behavioral health.

Receives: Behavioral: TLC Group Prenatal Care
Traditional Prenatal CareNo interventionSubjects randomized to routine care will receive their prenatal care with their primary obstetric provider. Patients are seen for 10-15 minutes every four weeks until 28 weeks' gestation, every two weeks (or more by provider discretion) until 37 weeks and weekly until delivery. Visits focus on routine screening tests and prenatal care. Traditional care participants will receive a phone call once a month, until 28 weeks gestation, from a nurse practitioner to check-in on pregnancy goals, healthy eating, and exercise. Each subject's medical chart will be reviewed for demographics, antenatal management, maternal and neonatal outcomes.

The record says: finished, as of the sponsor's last update on 18 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effects of TLC group prenatal care on birth weight (time frame: Delivery/within 1 week of delivery). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Feb 2026; AzTrials last refreshed its copy on 6 Nov 2026.
