Brief Summary

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.
