A study of deliveries in teenagers was undertaken for the year 1975 in a hospital that had recorded 2797 births, 371 (13%) of which were to women under 20 years of age. Conception had occurred out of wedlock in 314 (85%) of the 371 pregnancies; 124 of the 314 women had married during the pregnancy, most often in the 3rd or 4th month of gestation. The peak months for conception out of wedlock were June and December. This was not the first pregnancy for 65 women (18%), 21 of whom had married during a previous pregnancy. Of the "heads of the households" 36% were labourers and 27% were unemployed. Cesarean section was the method of delivery for 51 (14%) of the women, and 63 (17%) were reported as having had toxemia. There were seven perinatal deaths and seven infants had severe congenital abnormalities. The frequency of low birth weight was 6% overall but 13% for the infants of single women. Five women underwent tubal ligation post partum.
