Purpose: The purpose of this study is to describe women's concern for pregnancy and child birth in the internet community. Methods: One representative in the internet community was selected and questions regarding pregnancy and child birth were collected for 2 weeks in October 2019. A total of 8,005 questions were analyzed by frequency and proportion after categorizing theme into pregnancy, delivery, and postpartum care. Results: The most frequent questions were on preparedness for pregnancy (26.2%), followed by questions on infertility (23.3%), and on postpartum care (20.2%). Among the questions on preparedness for pregnancy, the most frequent questions were related to the follicle and ovulation. More than half of the questions on infertility (68.3%) were about diagnosis and treatment. Questions on abortion included symptoms, abortion procedure, post abortion care, and the support system. Among the questions on delivery, the most were about the delivery method (67.2%). Finally, questions on postpartum care were related to the physical changes/symptoms, daily life after delivery, postpartum care support, etc. Conclusion: As these results reflect women's need for information and support, it is suggested that more specific and targeted nursing practices for pregnancy and child birth should be developed.
