Introduction: Pregnancy is a special natural and physiological event that is not always normally and is responsible for morbidity and preventable mortality. Pregnancy risk is defined as one that is complicated by a factor or factors that negatively affect the outcome of pregnancy the mother's side and/or perinatal. This study was assigned as targets to determine the risk pregnancy prevalence and the factors associated with these pregnancies. Materiel and Method: We conducted a cross-sectional descriptive study at the General Hospital Katuba in Lubumbashi for a period of three months from March to June 2017. Result: Our results showed that 11.5% of pregnancies were high risk and moderate in 21.6%. Overall, pregnancies were high or moderate risk of 33.1%. A proportion of 19.8% of new mothers were aged over 35 years and 3.4% were under 18 years. The average age was 28.8 ± 7.2 years. Age greater than 35 years, multiparity, the high parity, the multigestity and the large multigestity were significantly associated with a risk

Maternal and child health is an important part in the health development plans in many countries. This descriptive study aimed to investigate the epidemiology of risk pregnancies managed at the provincial hospital Janson Sendwe. It was conducted from March 17 to July 15, 2015 to all pregnant women for childbirth consultant beyond 28 weeks of gestation and having at least one risk factor identified during antenatal care or a posteriori childbirth. On 535 women included in the study, we recorded 1667 risk factors in an average of 3.2 risk factors per woman. The three main risk factors were met by order of importance: the history of maternal infection (18.5%), the history of caesarean section (13.6%) and unexplained fetal or neonatal death antecedent (12.4%). The antecedent of uterine malformation (0.1%), the history of macrosomia (0.5%) and uterine height decreased (2.1%) were the least represented. It thus appears necessary to carefully monitor these women to avoid the occurrence of maternal mortality.
