The association between breastfeeding and resumption of post-partum menstruation (PPA) was examined in Bangladeshi women from the Bangladesh Demographic Health Survey (2004). Life table and Cox regression model were used. Breastfeeding was found to be statistically associated with PPA (p < 0.00) in bivariate and multivariate analysis. Hazard analysis show that administrative division, religion, mother’s education, work status, mother’s age, age at marriage, parity and contraceptive use
were statistically significantly associated with the probability of termination of breastfeeding. The study indicated that the duration of PPA significantly increased with increased the duration of breastfeeding practices.
