Purpose: This study was to investigate the status of Preconception Care (PC) and associated factors. Methods: A convenience sample consisting of 400 pregnant women who took maternity schools at a university hospital and a specialty hospital. Subjects, who agreed to participate in the study, completed self-administrated questionnaire (K-University hospital institutional review board) containing characteristics of preconceptional and pregnant period. Results: Although 84.7% of study subject perceived PC, only about half (54.1%) visited clinics for basic medical tests and treatments before pregnancy. The consultation rates on chronic diseases, drugs and spouse tests were even lower. Associated factors of PC included age (OR:0.114), prepregnant BMI (OR: 0.390), previous pregnancy (OR: 4.276), and perception on PC (OR:13.907). Conclusion: This study suggested that the academic and politic attention should be paid to PC management standards and related policies that include inter-conception care and sexuality education for adolescent.
