Objective To determine the relation between infant feeding practices (and other factors) and the duration of postpartum amenorrhoea in a sample of Chinese women Subjects &. Methods Infant feeding and the return of menses were measured longitudinally in 541 mothers and their infants in Pengxian County, Sichuan Province. The durations of breastfeeding and of lactational amenorrhoea were estimated through survival analysis. Cox’s non-parametric hazards regression analysis was performed to determine the variables associated with the duration of lactational amenorrhoea. Results Mothers breastfed frequently per day, the mean frequency ranging from 6. 4 per day at 3 weeks postpartum to 5. 4 per day at 6 months. They breastfed for over 18. 3 months on average. The median duration of lactational amenorrhoea was 9. 5 months. The period from birth until the first breastfeed was a significant determinant of the duration of lactational amenorrhoea, P = 0. 038. Compared with women who ended full breastfeeding earlier
