“…This is related to the growing concern in Brazil over the tendency to increasing prematurity, which affected 11.5% of live births in 2011 30 , a level far higher than in developed countries, where rates are around 7% 1,28,31 . In that scenario, it is fundamental to invest in measures to prevent avoidable prematurity, in addition to improving care for these more vulnerable newborns.…”

“…Data from the prenatal care card, which contains data recorded during the prenatal care visits, were also collected and recorded in a standard form. Based on such data, the gestational age at birth was determined from the ultrasound scan performed between gestational weeks six and twenty as ultrasound scan is considered the most accurate method for estimating gestational age 16,17 .
