About this study

Official title: The Chilean Maternal and Infant Nutrition Cohort Study II

The Chilean Maternal \& Infant Cohort Study II (ChiMINCs II) is an ongoing cohort that is part of the Chilean Maternal and Infant Nutrition Observatory of the South-East area of Santiago, Chile. In total, 1927 pregnant women beneficiaries of the public health systems and their offspring were recruited before 12 weeks of gestation and are followed across pregnancy (<15, 26-28, and 35-37 weeks of gestation) and up to 2 years of age of their offspring. Two studies are currently nested in ChiMINCs II: 1) Breast Cancer Risk Assessment in Mothers (BRECAM) study, and 2) the ChiMINCs-COVID study. The primary objective of BRECAM study is to test the association between maternal metabolic indicators (i.e., insulin, glucose, IGF-1, and HbAc1 concentrations) at early pregnancy (i.e., <15 and 26-28 weeks of gestation) and breast density 3 months after the cessation of lactation. For this purpose, we collect maternal obstetric, lifestyle, dietary intake, anthropometric, and biochemical information. The aim of the ChiMINCs-COVID study is to assess dietary-related risks and mental health problems derived from the COVID-19 pandemic and their influence on maternal and infant's health and nutrition. Thus, we collected detailed information on dietary behaviors, mental health and COVID-related information at each trimester, along with neonatal and infant nutritional information. The purpose of the present work is to describe the design, methods, and descriptive information at recruitment of ChiMINCs-II, also discussing the implications that this study can have to better understand maternal and infant nutrition and health during the COVID-19 era.

What participants receive

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

  • Nutrition and mental health during pregnancyOther

    Altered metabolic milieu is defined as a fasting glucose level >100 mg/dL at the first trimester of pregnancy by national guidelines. Altered metabolic milieu during the second trimester (24-28 weeks of pregnancy) is defined as a fasting glucose levels > 92 mg/dL and/or plasma glucose levels > 153 mg/dL two hours after load in the oral glucose tolerance test according to ADA guidelines or a fasting glucose >100 mg/dL and/or > 140 mg/dL two hours after load in the oral glucose tolerance test according to national guidelines. The COVID-19 pandemic is considered as a natural nutritional and mental health exposure.

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Density and Body Composition, run by Instituto de Nutrición y Tecnología de los Alimentos at 1 site in 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: status not confirmed, as of the sponsor's last update on 7 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Chile. 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?

Results are not available in the source record.

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?

Breast absolute (AFGV) fibro-glandular volume measured by DXA technique (time frame: Three months after breastfeeding cessation). The study lists 9 primary outcomes in all. 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 NCT03920098, which also lists 23 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 7 Feb 2022.
