Perinatal mortality and one-year infant morbidity.

Perinatal mortality in Southampton and South-west Hampshire Health District fell from 20.8 per 1000 total births in 1970 to 11.3 per 1000 in 1976. This was atributable mainly to a fall in the stillbirth rate, but also to a recent fall in the neonatal death rate in the first week. All infants born in 1975 who had any problems in the perinatal period were followed up for one year. Of the 12 children identified at one year as having a major handicap, eight suffered from problems of prenatal origin, two from problems associated with preterm delivery, and two from other conditions acquired during the perinatal period. As two-thirds of the major handicaps arose from congenital abnormalities, preterm delivery and low birth weight were not the main causes of major handicap.
