title: Area variations in birthweight- and cause of death--specific neonatal mortality rates in Italy.
abstract: The neonatal mortality rate in Italy is intermediate between the United States and the Northern European countries, but important regional differences exist within the country. On the basis of national data recorded by the Italian National Statistical Institute, birthweight- and cause of death-specific neonatal mortality rates were calculated for the whole country and for Northern, Central, and Southern Italy. The incidence of very low birthweight (500 to 1499 gm) and moderately low birthweight (1500 to 2499 gm) infants is similar in the three areas, whereas the risk of dying in the first month of life is highest in Southern and lowest in Northern Italy. Respiratory distress syndrome/immaturity is the main cause of neonatal death because of very high percent and component rates among very low birthweight infants and (to a lesser extent) among moderately low birthweight infants. Congenital disorders, which mainly affect normal weight newborns, are the second cause of neonatal death. Infants born in Southern Italy run a significantly higher risk of dying in the neonatal period than infants born in Northern Italy in almost all birthweight/cause of death subgroups, with the largest differences for moderately low birthweight infants. A similar but smaller difference is seen when infants born in Central Italy are compared with their Northern counterparts.
