Trial summary

Background: Women can gain too much weight or develop diabetes during pregnancy. If the mother is overweight or has diabetes during pregnancy, her baby may also be at risk of being overweight or developing diabetes. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • Women only
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • At least 18 years of age.
  • Receive prenatal care at the nurse midwifery/obstetrics service of PIMC and plan to continue receiving such care throughout the pregnancy.
  • Are able to have an OGTT prior to 16 weeks gestation (if diabetes was not previously diagnosed). Hyperemesis can preclude some pregnant women from successfully completing the OGTT; these women will not be excluded if the fasting blood samples can be obtained. Pregnant women with previously diagnosed diabetes are eligible if measures of glycemia (FPG, HbA1c, glycated albumin) are completed prior to 16 weeks gestation.
  • Estimated prenatal BMI >25 kg/m2.
  • Able to commit the time required for the interventions and follow-up.
  • Able and willing to provide informed consent.

Who cannot join

  • Contraindication to aerobic or resistance exercise (ACOG, 2002).
  • Twin or multiple gestation.
  • Severe anemia, uncontrolled asthma, uncontrolled hypertension, cardiac disease, or any condition that requires follow-up at specialty care clinics outside of PIMC (e.g., pregnancies at high risk for maternal or fetal demise).
  • Any condition that in the opinion of the investigators would interfere with consent, treatment, or follow-up.

About this study

Background:

  • Women can gain too much weight or develop diabetes during pregnancy. If the mother is overweight or has diabetes during pregnancy, her baby may also be at risk of being overweight or developing diabetes. A woman s chance of getting diabetes increases if her parents or family members are overweight or have diabetes. Poor diet and exercise habits can also lead to weight gain and diabetes. Researchers want to study how best to improve the health of pregnant women and their children. They will do so by providing healthy lifestyle counseling for women receiving prenatal care at the Phoenix Indian Medical Center.

Objectives:

  • To study the effectiveness of healthy lifestyle counseling for overweight and/or diabetic pregnant women.

Eligibility:

  • Women at least 18 years of age who will receive pregnancy care at the Phoenix Indian Medical Center.
  • Participants must be overweight or obese. They may or may not have diabetes.

Design:

  • Participants will receive standard prenatal care from the midwives, doctors, and dietitians at the Phoenix Indian Medical Center.
  • Participants will work with National Institutes of Health staff for about 2 hours every week. These sessions may include phone calls, home visits, or group meetings.
  • Participants will have a total of nine measurement visits. The first visit will be at or before 16 weeks of pregnancy. The next three visits will be within a week of the first visit. Another four visits will take place between 23 and 28 weeks of pregnancy.
  • Participants will have different tests through their pregnancy. They will wear heart monitors and wrist monitors to measure heart rate and movement. They will provide information on their eating habits, physical activity, and mood and feelings during pregnancy. Blood samples will be collected to measure blood glucose (sugar) levels.
  • Participants will receive counseling on healthy eating and physical activity habits. They will be encouraged to invite friends or family members to learn more about healthy lifestyle choices.
  • The study will end with the final visit about 6 to 8 weeks after giving birth. A final blood sample will be collected. Participants will be asked questions about mood and feelings.
Read the detailed description

American Indians are at high risk for developing type 2 diabetes mellitus (T2DM) and its complications. Major factors responsible for this finding include obesity and intrauterine exposure to diabetes; the latter increases the risk of diabetes in the offspring particularly during childhood and adolescence. This study is designed to evaluate the feasibility of conducting an intensive lifestyle intervention (ILI) in adult (age greater than or equal to 18 years) pregnant women of any race or ethnicity who are eligible for prenatal care at Phoenix Indian Medical Center (PIMC). Most of these women or their fetuses will be of American Indian heritage. Interventions will be provided to overweight and obese pregnant women who may have diabetes, develop gestational diabetes (GDM), or be at high risk of developing diabetes. We will evaluate our ability to maintain engagement and motivate adoption of a healthy diet and increased physical activity. The lifestyle intervention will be patterned after the Diabetes Prevention Program (DPP) that prevented or delayed the onset of diabetes in non pregnant adults; the interventions will be modified to be appropriate in pregnancy. A major modification will be to encourage managed weight gain instead of weight loss. For women who have or develop diabetes, interventions will include coaching to optimize glycemic control. In this protocol, we will seek to identify strategies that can successfully accomplish these goals. Results from this study will permit us to formulate appropriate intervention strategies for a large randomized clinical study to evaluate the impact of an intensive lifestyle intervention on pregnant women and their offspring.

The project will be conducted in collaboration between the nurse midwifery and obstetrics services at Phoenix Indian Medical Center (PIMC) and the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). Important feasibility measures include evaluating our ability to enroll and retain pregnant women in a lifestyle intervention program and collect serial measures of gestational weight and glucose, objective measures of physical activity, and nutritional questionnaires.

Questions about this trial

What is this clinical trial studying?

An observational study of Hperglycemia and Diabetes Mellitus, run by National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 16 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.

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 was withdrawn before enrolling participants, so there are no results.

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?

Gestational Weight Gain. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01585454, which also lists 3 linked publications.

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 16 Dec 2019.
