While the primary concern is with the problem of perinatal and infant mortality in this country, it was felt that much could be learned from the experience of other developed countries with advanced medical sys tems. During the period 1950-65, infant m,ortalit y was no lcnger declining at its former pace in the United States and in several other countries (England and Wales, and Scotland, for example) but in the Netherlands and Sweden, the rates appear to have declined to a level which is about half of that in the United States. Despite declines in infant mortality for the United States in 1966 and 1967, the differential between this country and the Scandinavian countries remains evident. The National Center for Health Statistics arranged with a number of investigators to prepare comprehensive reports on perinatal and in fant mortality in their own countries. Contracts were negotiated with investigators in Denmark, England and Wales, the Netherlands, Norway, Scotland, and the United States. Earlier reports evolving from these contracts appear in Series 3 of Vital and Health Statistics: No. 4 Infant and Perinatal Mortality in the United States No. 5 Infant and Perinatal Mortality in Scotland No. 6 International Comparison of Perinatal and Infant Mortality: the United States and Six West European Countries No. $ Infant Mortality Problems in Norway No. 9 Infant and Perinatal Mortality in Denmark The present report for the Netherlands is the sixth in this group of studies on perinatal and infant mortality. The methodology, findings, and conclusions are those of the investigators. Iwao M. Moriyama, Ph.D. Director Office of Health Statistics Analysis ... 111 CONTENTS Page ..

The trends in infant and pevinatal mortality are analyzed in the light of changing pat tevns of medical demography, the organization and development ofhealth and medical services, and the general standard of living. Infant mortality was ~educed by hulf in each of three periods: between 1900 and 1922, between 1923 and 1939, and between 1948 and 1964. All age components of infant loss (fetal and infant mortality) have decreased more rapidly in the postwar thun in the prewar years. Perinatal mor tality has fallen much move slowly thunpostnatal mortality (1-51 weeks), drastically chan~”ng the vatio of these two components j?om 1 to 1 in 1927 to 3 to 1 in 1950-54 and to 5 to 1 in 1960-64. Currently, perinatal mortality accounts for more than 80 percent of infant loss. Obstetrical care in the Netherlands has three distinctive chmacteristics. Fi%st, domiciliary confinement with the sevvices of a family doctor OY midwife is far moye usual than institutional confinement, with only 30 pevcent of the bivths occuming in a hospital. Second, midwives give pvenatul and natal cave as independent practitioners. Third, a special voluntwy organization pvovides caye in the home foy mothev and the newbovn. A veview of infant and perinatal mon?ulity by sex, age, cause of death, social class, and other facton indicates that jiwther reductions I in infant loss in the Netherlands may be expected. ...
