The duration of postpartum amenorrhoea was studied in a Danish sample of 361 women. The median duration of amenorrhoea was 17 weeks. The 25th and 75th percentiles were 10 and 30 weeks, respectively. A significant correlation was found between the duration of postpartum amenorrhoea and of breast-feeding. However, lactation for more than 9 months did not extend the duration of amenorrhoea. Menstruation before weaning occurred in 57% of the women, and 43% terminated breast-feeding before the first menstruation. Four weeks after weaning menstruation had returned in 79% and by 8 weeks after in 93% of the mothers. At 6 months postpartum, frequency of breast-feeding, and of night-time feeding were determinants of amenorrhoea. [ABSTRACT FROM AUTHOR]

A longitudinal interview study of 360 mothers was carried out to investigate: 1) utilization of maternity leave by the parents, 2) mothers' resumption of occupation after delivery and 3) duration of breast feeding seen in correlation with the mothers' resumption of work. 1) 95% of the families utilized the entire maternity leave. In 92% of the families, the mothers utilized all 24 weeks and, in 3% of the families, the fathers took part in the maternity leave. Only 46% of the fathers utilized the right to take leave in connection with delivery and 14% employed their holiday but were at home for a significantly shorter period. 2) Only one fourth of the mothers had resumed work 24 weeks after the delivery. 44% of the mothers prolonged the maternity leave with their holiday and 32% prolonged the maternity leave even longer. One year after delivery, significantly more mothers were housewives than previously. 3) A significantly positive correlation was found between the time for maternal return to work and the duration of breast feeding. We conclude that almost all of the families utilized the maternity leave and that prolongation of maternity leave (which is 24 weeks after delivery at present) might be necessary.

A longitudinal prospective study was performed to investigate the total duration of breast-feeding. Three hundred and sixty six mothers were followed-up until three years after delivery. At three months, 73% were breast-feeding, at six months 52%, at one year 20% and 1% breast-fed more than three years. Correlations were found between duration of breast-feeding and maternal age, education and social class. Mature mothers who lived under good socioeconomic conditions breast-fed for longer periods than those who were less fortunate in these respects. Mothers who had breast-fed an older child usually breast-fed the next child for a similar period. Breast-feeding has become popular: only 1% did not want to breast-feed at all and 89% of mothers intended to breast-feed their children for six months or more. Solid food was most frequently introduced when the infants were four months old. At six months 4% were still exclusively breast-fed. Even though the mothers now breast-feed longer than previously, only 39% succeeded in breast-feeding for as long as or longer than they had intended.

At 1 month 93% were breast-feeding, at 3 months 73%, at 6 months 52%, at 1 year 20% and 1% breast-fed more than 3 years. Correlations were found between duration of breast-feeding and maternal age, education and social class.

Breast-feeding has become popular: only 1% did not want to breast-feed at all and 89% of mothers intended to breast-feed their children for 6 months or more. Even though the mothers now breast-feed longer than earlier, only 39% succeeded in breast-feeding for as long as or longer than they had intended.

The initiation and the prevalence of breast-feeding after discharge from hospital was investigated in 370 singleton parturients and compared to the mode of delivery. Infants delivered by vacuum extraction or by caesarean section started suckling later, they were more often given formula prescription during the first 4 days, they were less often breast-fed during the night, and their mother's milk 'came in' later, but it did not affect the prevalence of breast-feeding after discharge. A sleepy infant, which was not very willing to suckle, was the most frequent nursing-problem mentioned by the mothers 4 days after delivery. Failure to start breast-feeding occurred in only 2.2% of the women, and after 6 months 52% were still breast-feeding their children.

Infantile colic (IC) is a distressing condition with an unclear etiology. A prospective trial was undertaken to study the hypothesis that medication during labor increases the risk of IC. Of 365 singleton deliveries, 70 (19%) developed IC. The factors associated with a significantly increased occurrence of IC were: a "psychological" complication of pregnancy, a sibling with a history of IC, a bad subjective experience of pregnancy and second parity. No significant association to "true" obstetrical complications or labor occurrences (breech, vacuum extractor, cesarean section, shoulder dystocia, pudendal block, epidural analgesia, general anesthesia or intravenous Syntocinon) was found. Modern management of labor does not increase the risk of IC. Prevention of IC is therefore achieved by psychological support to the pregnant women in the risk groups, and not by depriving her of necessary obstetrical management or pain relief.
