Abstract Low birth weight rate is still high. Low birth weight increased the risk of perinatal and infant mortality and morbidity. This study aims to know the relation between antenatal care (first visit, frequency, iron pill consumption) and low birth weight controlling for infant?s gender, maternal age, maternal education, parity, birth space and history of abortion. 5 The study design is unmatched case-control nsed Indonesia Demographic and Health Survey 1997 (IDHS 1997) data wherein 748 cases and 1496 controls were selected among singleton infants were carried out in IDHS 1997- This study found: the mother of cases have 1.29 times having first visit at the second or third trimester of pregnancy compared to the controls controlling for maternal age, maternal education and birth space. The mother of cases have 1.81 tlmes having visit frequency less than 4 times compared to controls controlling for maternal age and birth space. The mother of cases have 1.89 times having iron pill consumption less than 90 pill compared to the controls controlling for visit frequency, maternal age, maternal education and birth space. The attributable risk of first visit was 22.5 %, visit freqneudy was 44.8 % and iron pill consumption was 47.1 %. This study recommend: 1). to control for the availability and distribution of iron pill 2). to add other questions into IDRS questionnaire, eg. maternal blood tension, height, weight and anemia?s status 3). to give informations for girls and young mothers about the reproduction health with the main messages are marriage age/birth age and birth space 4). to analyze the last IDHS data.
