Early Childhood Obesity Programming by Intrauterine Growth Restriction

September 8, 2025 updated by: Montefiore Medical Center

Molecular Basis of Early Childhood Obesity Programming by Intrauterine Growth Restriction

The molecular mechanisms underlying developmental programming of childhood obesity remain poorly understood. Here, the investigators address major questions about early childhood obesity programming by studying CD3+ T-cells from intrauterine growth restricted (IUGR) newborns who have an increased risk for obesity and other metabolic disorders in adult life.

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.

Detailed Description

Epidemiological studies of multiple cohorts suggest an increased risk for obesity, cardiovascular disease-related death and type 2 diabetes in low birth weight infants. However, the molecular mechanisms underlying developmental programming of childhood obesity remain poorly understood. Alterations in DNA methylation during fetal life have been proposed to be one of the mechanisms that regulate this phenotype. Here, the investigators address major questions about early childhood obesity programming by studying purified subpopulations of CD3+ T-cells from intrauterine growth restricted (IUGR) newborns who have an increased risk for obesity and other metabolic disorders in adult life. The investigators will correlate altered CD3+ T-cell DNA methylation profiles in cord and peripheral blood samples and functional changes in CD3+ T-cells with adiposity in childhood.

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

1 hour to 2 years (Child)

Accepts Healthy Volunteers

Yes

Sampling Method

Probability Sample

Study Population

Term AGA and IUGR singleton infants

Description

Mother-infant pairs will be recruited for this study.

Inclusion Criteria:

  • Healthy singleton term intrauterine growth restricted (IUGR) and appropriate for gestational age (AGA) infants whose mothers are followed by the Obstetric Department of Montefiore Medical Center and who deliver at the Weiler Division of Montefiore Medical Center. Infants will be classified as IUGR if birth weight is <10th percentile for gestational age and gender based on World Health Organization (WHO) growth curves. Infants will be classified as AGA if birth weight percentile is >10th and <90th percentile
  • Reproductive age women, healthy enough to achieve pregnancy
  • Deliver a single healthy live term infant at ≥37 weeks' gestational age (GA)
  • All patients must be informed of the investigational nature of this study and must sign and give written informed consent in accordance with institutional and federal guidelines

Exclusion Criteria:

  • Multiple gestation
  • Maternal depression
  • Maternal renal disease
  • History of maternal smoking in the 2nd and 3rd trimester of pregnancy
  • Maternal gestational diabetes / Type 2 Diabetes (T2D)
  • Preterm birth (less than 37 weeks' gestation)
  • Known chromosomal or congenital anomaly
  • Infants in extremis
  • Low Apgar scores (Apgar score <7 at 5 minutes of age)
  • Known congenital bacterial or non-bacterial infections
  • Known inborn errors of metabolism

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.

Change in growth velocity based on DNA methylation marks and functional profiles of CD3+ T-cells
Until 24 months of age
DNA methylation of CD3+ T-cells
Time Frame: At birth and 24 months of age
Change in DNA methylation of CD3+ T-cells in the first 24 months of life in IUGR infants
At birth and 24 months of age

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.

Primary Completion (Estimated)

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.
