Early Risk of Asthma in Children Exposed to In-utero Maternal Obesity
An observational study of Asthma and Children, run by Pontificia Universidad Catolica de Chile.
Trial summary
This study seeks a better understanding of the pathogenesis of asthma in early life. The aim of this project is to determine whether the offspring of obese mothers at 3 years of life have increased the risk of asthma compared to children whose mothers were not obese and whether this increased risk is associated with a… Read more about this study

- Adult
Study population: The recruitment of participants was performed in the Sotero del Rio Hospital at Santiago. Women that were obese (BMI>30) or normal weight (BMI<25) at their first antenatal visit were invited to participate in the study at the moment of delivery. Questionnaires: Information regarding birth outcomes, maternal and paternal history of asthma and allergy, as well as environmental conditions at home (pet ownership, indoor smoking, heating system, and so on) was collected using a questionnaire at the moment of recruitment. Follow-up questionnaires by phone are completed every 6 months. These questionnaires collect information regarding diagnosis of asthma/allergy and acute respiratory illness, environmental conditions, and relevant confounding variables
Who may be able to join
- Women who receive care in any of the 12 public health care centers in La Florida and Puente Alto and give birth in the Sotero del Río Hospital.
- Singleton pregnancy of fewer than 14 weeks of gestation at the first antenatal visit.
- 18 years or older
Who cannot join
- Pregnant women with overweight (BMI 25-30) before 14 weeks.
- Women that have a premature birth, cardio-respiratory disorder or neurological defects of the neonate.
- Women that develop gestational diabetes and hypertension during pregnancy
About this study
Official title: Early Risk of Asthma in Children Exposed to In-utero Maternal Obesity: An Epigenetic-mediated Programming of Immune Function
This study seeks a better understanding of the pathogenesis of asthma in early life. The aim of this project is to determine whether the offspring of obese mothers at 3 years of life have increased the risk of asthma compared to children whose mothers were not obese and whether this increased risk is associated with a programming altered immune reactivity at birth.
Read the detailed description
The general objectives of this study are:
- To determine whether the increased risk of asthma in children born from a pre-pregnant obese mother can be observed at 3 years of life and whether this increased risk associated with altered plasma levels of immune mediators at birth.
- To explore in children born from pre-pregnant obese mother whether monocyte physiology and M1-M2 polarization present an altered response and expression of asthma-related immune-modulations at birth.
- To study in neonates born from pre-pregnant obese mother whether the in vitro expression of TNFα, IL12, IL-10 and IL-4Rα in monocytes associates with changes in the DNA methylation status in the promoter regions of those genes.
The study is performed in accordance with the Helsinki Declaration, and the study protocol was accepted by Institutional Review Boards at School of Medicine of the Pontificia Universidad Católica de Chile.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Newborn from obese and nonobese pregnant | Obese (BMI>30) or normal weight (BMI<25) women at their first antenatal visit were invited to participate in the study at the moment of delivery at Sotero del Rio Hospital, Santiago. Information regarding birth outcomes, parental history, as well as environmental conditions was collected at recruitment. Follow-up questionnaires by phone were completed every 6 months. Umbilical cord blood samples were collected to measure IL-12, TNF-α, IL-10, IL-4; to evaluate metabolic status; to isolated monocytes and macrophage differentiation; and for DNA methylation status of the promoter regions of the genes coding for TNF-α, IL-12, IL-10, and IL-4Rα. Also, fasting blood samples of the mothers within 48 hours after delivery; and blood samples and skin prick test were collected. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Risk of asthma (defined as "positive asthma predictive index" at 36 months of age)
Measured: 36 months of age
Secondary outcomes (1)
Allergy status (positive skin prick test)
Measured: 30-36 months of age

Questions about this trial
What is this clinical trial studying?
An observational study of Asthma and Children, run by Pontificia Universidad Catolica de Chile.
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 3 inclusion and 3 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: finished, as of the sponsor's last update on 10 Sep 2021. 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 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?
Risk of asthma (defined as "positive asthma predictive index" at 36 months of age) (time frame: 36 months of age). 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 NCT02903134, which also lists 5 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 10 Sep 2021.
