Chilean Maternal-Infant Cohort Study-II (CHiMINCs-II)
The CHiMINCs-II is an ongoing cohort that is part of the Chilean Maternal and Infant Nutrition Observatory (CHIMINO) of the southeast area of Santiago, Chile. In total, 1,954 pregnant women beneficiaries of the public health systems and their offspring were recruited before 15 weeks of gestation and are followed across pregnancy and up to 2 years of age in their offspring. Two studies are currently nested within the CHiMINCs-II cohort: (1) the Breast Cancer Risk Assessment in Mothers (BRECAM) study, and (2) the CHiMINCs-COVID study. The mean age of the participants was 29 years; most were single (53%), and had completed 12 years of education (71%).
