1997-98 Sao Luis Cohort Study
The study identified over 2,500 hospital births in São Luís, Brazil, representing approximately 96.3% of all births in the area during the specified time frame, ensuring the sample's representativeness. Data collection spanned from March 1, 1997, to February 28, 1998, across 10 units. After excluding twins and stillbirths, 2,443 singleton births were included for analysis, with a 5.8% loss rate due to refusal or inability to locate mothers, mirroring variables collected in a prior cohort study from 1994 in Ribeirão Preto, Brazil.
