title: [Studies of obstetric and socioeconomic factors in the origins of prematurity].
abstract: Data of 400 term deliveries and 100 preterm deliveries were analyzed to determine the effect of the socio-economic situation, prior abortion, premature birth and other complications on current pregnancy outcome. Of special interest was the question if pregnancy complications in an antecedent pregnancy would lead to intensified care in a following pregnancy. A prior premature birth increases the risk for prematurity significantly. In contrast to earlier studies illegitimacy has no influence on rate and outcome of preterm birth. It is the most striking result of this study that a high risk factor as previous abortion, stillbirth or prematurity gives no cause for improved or intensified prenatal care.
