Some characteristics of labor in ethnic minorities in Amsterdam.

A retrospective study of labor in immigrants, subdivided into Blacks, Asians and Mediterraneans (Turks and Moroccans) and autochthonous Dutch in Amsterdam over a 10-year period showed definite differences. The second stage was shortest in Blacks and Mediterraneans but they sustained perineal tears and episiotomies less frequently. Differences in positions at birth were small except for occipito-posterior position which was very rare in Asians and Mediaterraneans. The rate of cesarean section was highest and that of instrumental vaginal delivery lowest in Blacks, and latter being highest in Asians. Retained placenta occurred less often in immigrants than in Dutch.
