ABSTRACT
PIP: Breastfeeding is thought to be the major determinant of prolonged postpartum amenorrhea (PPA) and anovulation in societies where nursing is virtually universal, prolonged, and of high intensity. Considerable variation, however, exists within and between societies in the length of PPA during which breastfeeding suppresses fertility. The authors investigate the association between breastfeeding and the resumption of menses and the impact of various biological and social covariates thereon. Findings are based upon data drawn from 2 retrospective surveys conducted in India over the period 1987-89 and analyzed with both univariate life table and multivariate time-dependent hazards techniques. Since breastfeeding beyond the resumption of menstruation cannot affect the duration of menses, this study treats breastfeeding as a time-dependent covariate. Analysis revealed that breastfeeding, age of mother at child's birth, social status, level of income, religion and caste, and residential status have significant effects on the return of menses in Indian traditional society.
