Background : Maternal knowledge regarding pregnancy danger signs is an important determinant of health-seeking behavior during pregnancy. Adequate knowledge enables pregnant women to recognize potential complications early and encourages compliance with recommended antenatal care (ANC) visits, thereby reducing delays in obtaining appropriate medical care. However, adherence to ANC visits remains a challenge in many primary healthcare settings. This study aimed to determine the relationship between maternal knowledge of pregnancy danger signs and compliance with antenatal care visits at Papusungan Primary Health Center. Methods : This quantitative analytic study employed a cross-sectional design. A total of 60 pregnant women were recruited using consecutive sampling based on predefined inclusion criteria. Maternal knowledge was assessed using a structured questionnaire that demonstrated satisfactory validity and reliability, while ANC compliance was determined through maternal health records and the Maternal and Child Health (MCH) Handbook. Data were analyzed using descriptive statistics, Chi-square tests, and binary logistic regression, with statistical significance established at p < 0.05. Results : Among the respondents, 46.7% demonstrated good knowledge regarding pregnancy danger signs, while 68.3% were compliant with the recommended ANC schedule. Chi-square analysis revealed a statistically significant association between maternal knowledge and ANC compliance (p = 0.001). Binary logistic regression further indicated that women with good knowledge were 5.84 times more likely to comply with ANC visits than those with poor knowledge (OR = 5.84; 95% CI = 1.82–18.71; p = 0.002). Conclusion : Maternal knowledge of pregnancy danger signs was significantly associated with compliance with antenatal care visits at Papusungan Primary Health Center. Strengthening health education through antenatal counseling, maternal education classes, and continuous health promotion is recommended to improve maternal awareness and ANC attendance. Future studies involving larger populations, multicenter settings, and longitudinal designs are recommended to provide stronger evidence regarding factors influencing ANC compliance.
