Early pregnancy in school settings remains a major public health and social concern in the Democratic Republic of Congo, particularly in rural areas affected by socioeconomic challenges. Although pregnancy is not a disease, its occurrence among adolescents is often unintended and has serious consequences for health, education, and social integration. This study aimed to identify factors associated with early pregnancy among adolescents in the Léproserie neighborhood, located in the Mopela health area within the rural health zone of Bwamanda (South Ubangi). A cross-sectional study was conducted between July and September 2023 using field surveys and interpersonal interviews. A non-probability sampling method included 59 participants (43 girls and 16 boys) who had experienced pregnancy or fatherhood before the age of 18. The results indicate that most adolescents initiated sexual activity between the ages of 13 and 15, while regular condom use was low. The main reasons for non-use included perceived loss of sexual pleasure, partner refusal, and cultural or religious constraints. The findings highlight the combined influence of socio-cultural, economic, and educational factors, compounded by limited access to sexual and reproductive health information. The study underscores the need to strengthen comprehensive sexuality education, encourage parental involvement, and improve access to reproductive health services to reduce early pregnancies among school-aged adolescents.
