Reproductive-age women require effective methods to control the timing of their births and limit the number of children they have. This requirement can be achieved by using modern postpartum contraceptive methods that are provided through maternal and infant health services. This study examined the link between maternal-infant health services and modern contraceptive use among postpartum women aged 15-49, using 2017 Indonesia Demographic and Health Survey (IDHS) data from 6,309 women. A cross-sectional design and logistic regression analyses revealed a positive association: women receiving comprehensive maternal and infant health services were 1.5 times more likely to use modern contraceptives. Other significant factors included education, income, maternal status, number of children, pregnancy and delivery services, sexual activity, intent, family planning discussions, and information from healthcare providers. To improve contraceptive access, BKKBN should strengthen the infrastructure, training, and field worker coordination. The Ministry of Health should enhance field evaluations of integrated maternal and infant health contraceptive services.
