The foundation for preferment of family planning (FP) to delay conception after a recent birth is a best practice that can lead to optimal maternal and child health outcomes. However, in case of Bangladesh little is known about how pregnant women arrive at their decisions to adopt post-partum modern family planning (PPMFP). Postpartum months are a challenging time for women and they are quite neglected in our social context. This period is very much vulnerable for next conception. As ante natal care is a popular program in country in contrary to post natal care. So during ANC the advice of PPMFM would be a productive effort. The objective of this study to examine the association between antenatal care seeking behavior and the use of modern contraceptive methods among postpartum women. We used 17,842 women of reproductive ages 15–49 from the 2011 BDHS data set, who had a birth in the 5 years preceding the survey. We then applied both descriptive analyses covering Pearson’s chi-square test and later a binary logistic regression model to analyze the comparative contribution of the various maternity and socio-demographic conjecturers of uptake of modern contraceptives during the postpartum period. About 62.4% of total ANC seekers used modern postpartum family planning methods in Bangladesh. PPMFP was significantly associated with primary or secondary education (OR=1.22; OR=1.21 respectively); exposure to media (OR=1.21); religion (OR=.708) and age of woman at first birth (OR=0.97). In addition, PPMFP was associated with number of surviving children, regional variation and place of residence. This study shows the significant association between antenatal care and postpartum contraceptive use in Bangladesh. Integrating family planning counseling into antenatal care may increase the use of effective contraceptive methods among postpartum women in Bangladesh.
