Perinatal Moality rate includes:

Perinatal moality rate has great significance in assessment of both obstetric and pediatric care before and around the time of bih. It includes both stillbihs and early neonatal deaths (neonatal deaths under one week of age). Perinatal moality accounts for 90% of all fetal and infant moality in the developed countries. With improved obstetric and perinatal technologies, the perinatal moality has gradually declined in the developed countries. PERINATAL MOALITY RATE (In nations with less established vital records of stillbihs) = LATE FETAL DEATHS (28 WEEKS GESTATION AND MORE) + EARLY NEONATAL DEATHS (FIRST WEEK) IN ONE YEAR _____________________________________________________ X 1000 LIVE BIHS IN THE SAME YEAR or PERINATAL MOALITY RATE (FOR INTERNATIONAL COMPARISONS RECOMMENDED BY WHO) = LATE FETAL AND EARLY NEONATAL DEATHS WEIGHING OVER 1000 GMS AT BIH X 1000 TOTAL LIVE BIHS WEIGHING OVER 1000 GMS AT BIH Ref: Park's Textbook of Preventive and Social Medicine, 19th Edition, Pages 449-451
