Exclusive Breastfeeding Improves Puerperal Glucose Metabolism in Pregnant Women With Gestational Diabetes Mellitus and Links to Lipids Composition

November 27, 2022 updated by: Xirong Guo, Nanjing Medical University

Women's Hospital of Nanjing Medical University

Breastfeeding could effectively be associated with a lower risk of future type 2 diabetes (T2D) in women with gestational diabetes mellitus (GDM), but the short-term protective impact of puerperal breastfeeding on maternal metabolic recovery of GDM women remains unascertained. The investigators recruited GDM participants at 6-9 weeks postpartum and retrieved clinical diagnoses of GDM from electronic medical records. Feeding patterns were collected via phone calls. Glucose metabolism parameters and lipid profiling were performed on fasting plasma samples collected from patients 6-9 weeks postpartum (20 breastfeeding cases vs. 15 formula feeding cases).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

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 to 35 years (Adult)

Accepts Healthy Volunteers

Study Population

women (aged 18-35 years) who delivered live-born infants equal to or greater than 37 weeks of gestation at the Women's Hospital of Nanjing Medical University (Nanjing, China) and were not using medications affecting glucose tolerance, lipid regulation and not planning another pregnancy within the next 2 years were enrolled. All the participants received 75g OGTT at 24-28 weeks of gestation and were diagnosed with GDM based on the IADPSG criteria (International Association of Diabetes and Pregnancy Study Groups Consensus Panel et al.). At 6-8 weeks postpartum, all the participants were administered regularly for a post-natal health check-up to classify the body and genitals basically restored status. Fasting plasma samples were collected to measure plasma glucose, and insulin, and reclassify glucose metabolic status. Frequency and amount of breastmilk feeding and formula feeding for each woman were evaluated by trained research staff via telephone calls.

Description

Inclusion Criteria:

  1. 18-35 years old;
  2. gestational age greater than 37 weeks;
  3. Body Mass Index (BMI) before pregnancy 18.5-28kg/m2;
  4. Have normal listening and speaking skills, can communicate, and are willing to participate in this study.

Exclusion Criteria:

  1. abnormal glucose metabolism or diabetes has been diagnosed before pregnancy;
  2. assisted reproduction;
  3. GDM patients requiring drug treatment;
  4. The use of blood lipid regulation drugs;
  5. other pregnancy complications and complications;
  6. Suffering from heart, malignant tumor, kidney and other major organ diseases;
  7. associated with neurological dysfunction and cognitive impairment;
  8. Failure to cooperate with follow-up observers.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 1, 2021

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
