Introduction: our study describes the state of knowledge of the risks associated with pregnancy and analyzes the factors that influence the use of ANC services by women aged 15 to 49 living in the former province of Katanga. Methodology: the study is descriptive and analytical. The data analyzed were collected by the survey conducted in 2014 by the PARSS II / RDC project. We used SPSS.20 software for data processing. Results: 86.8% of women who gave birth in the last 12 months declared having followed ANC. More than 90% of them had consulted nurses or midwives; over 49% believe that consultation costs are either relatively expensive or very expensive. More than 30% of women say they were not educated on danger signs during ANC. Knowledge of the danger of pregnancy; pregnancies too close together and the cost of consultations are significant factors in the decision to use antenatal consultation services. Conclusion: the low proportion of women who know the signs of risk during pregnancy, the low proportion of those who have received information on these signs and the high cost of ANC advocate for the strengthening of health education in rural areas, the training and motivation of health personnel working in rural areas and the assumption by the community of the costs of ANC.
