A study on perinatal mortality in Gifu Prefecture

—Comparison between Gifu Prefecture and the whole of Japan—

Abstract

Perinatal mortality rates and proportion of deliveries by birth weight, maternal age, birth order, single or multiple birth, sex, place of delivery, and delivery attendant, were compared between Gifu Prefecture, and Japan as a whole in 1974. The results were as follows: 1. The perinatal mortality rates in Gifu Prefecture were higher than those of Japan as a whole. 2. The difference between perinatal mortality in Gifu Prefecture, and those in Japan, was related to the proportion of low, birth-weight deliveries.
