Background: Fear of childbirth is one of the most common problems among pregnant women that can threaten their and their baby’s health. Therefore, the purpose of this study was to explore the causes and grounds of childbirth fear and the strategies used by pregnant adolescent women in Iran to overcome such fears. Methods: In this study, which was conducted among primiparous Kurdish women in Iran, conventional qualitative content analysis was used. Data were selected through purposive sampling and semi-structured interviews. Data saturation was reached with 15 participants. The Lincoln and Guba criteria were used to strengthen the research. Results: After analyzing the data, two main categories were resulted. The first category was fear of childbirth with subcategories of fear of child health, fear of childbirth process, fears about inappropriate medical staff performance, fears about hospital environment, and postpartum fears. The second category was strategies to reduce childbirth fear with subcategories of choosing appropriate medical centers, increasing information on childbirth, avoiding stressful sources, improving self-care, getting prepared for delivery day in advance, and resorting to spirituality. Conclusion: Pregnancy in adult age is better than adolescent age. The women’s fear can be reduced by increasing their assurance about child health, providing appropriate training during pregnancy, explaining the whole process of childbirth and making it easier, improving the hospital environment and medical staff specialization, as well as providing appropriate conditions for further care and support after birth.
