Antenatal and postnatal care services are the most effective interventions to improve maternal health and prevent maternal and infant deaths. We conducted a cross sectional study in Chuadanga Sadar Hospital, Bangladesh during the period from 10^th August 2018 to 15^th September 2018. The study aimed to identify the factors affecting antenatal care and postnatal care among reproductive aged women in Chuadanga district of Bangladesh. A total number of 300 ever-married reproductive aged women with at least one child from Chuadanga District of Bangladesh were interviewed through a structured questionnaire using purposive sampling technique. Majority of the respondents were aged between 20-25 years, secondary educated, housewife, Muslim, got married between the ages 16-18 years. Chi-square test reveals that, respondent’s age, education, age at first marriage, age at first birth, nutritional status, monthly family income and expenditure, husband’s occupation, place of residence and number of child ever born are associated with both of antenatal care and postnatal care. Maternal health services become a national health concern in Bangladesh; however, delivery care and post-natal care are quite low, therefore, the government of Bangladesh should implement interventions to increase awareness and availability of health facilities in order to improve the coverage of maternal health services.
