The observed association between f and fetal weight suggests that fMRI could be suitable for studying placental insufficiency and for identifying risk of SGA.
perinatal complications in post-term girls than in post-term boys. The purposes of this study were to investigate the sex ratio of post-term pregnancies and differences between post-term boys and girls in perinatal complications (stillbirth, low Apgar score, low birthweight, meconium aspiration and low umbilical artery pH) in Dalarna County, Sweden. Methods: Data from gestational week ≥39 of singleton pregnancies in Dalarna County (13 February 2006-15 January 2014) were collected from the Obstetrix ® medical records system. Results: The neonatal male:female ratio increased with age after gestational week 40, as dated by ultrasound, reaching 1.69 in gestational week 42. This ratio remained 1 throughout gestation according to dating by the last menstrual period. Post-term pregnancy increased the risks of meconium aspiration and low Apgar score, with no sex difference observed. Conclusions: Ultrasound dating indicated that more boys than girls were born post term, whereas dating according to the last menstrual period revealed no sex difference. These results supports the hypothesis that girls are smaller than boys, leading to the underestimation of their age, at the time of second-trimester ultrasound examination.
