Introduction: In this study, it was aimed to evaluate preconception counseling and pregnancy planning status and to determine the relationship between these status and knowledge about folic acid (FA), use of FA and smoke exposure in pregnant women. Methods: This study was carried out as a cross-sectional study between January-April 2015 among women who applied to Karadeniz Technical University Medical Faculty for pregnancy follow-up (n=199). Participants' demographic characteristics, preconception counseling and pregnancy planning status, knowledge and use of FA, smoking and passive smoking were evaluated by applying a questionnaire face to face interview method. Descriptive statistics, Student t test, Mann-Whitney U test and Chi square test were performed. Statistical significance level was taken as p <0,05. Results: The mean age of participants was 30.2 ± 5.8 years. Twenty-six percent of the participants had consulted by any doctor for preconception care. The proportion of women who indicated that they planned current pregnancy was 63.8%. While rate of those who stated that they use regular FA was %62,8, ten percent of them started to use it before conception. The rate of those who continued to smoke during pregnancy was 6,5% and 32% of the participants were exposed to smoke. In pregnants with preconception counseling; rate of pregnancy planning, using FA before pregnancy and knowing that FA prevented birth defects were higher (p<0,05). There was no statistically significant relationship between demographic characteristics, regular FA use and smoking exposure and preconception counseling (p> 0,05). Conclusion: Preconception care services, a very important opportunity in terms of improving the health of women and possible children, have been found to be inadequate in our study. All health workers who serve women in the reproductive age should be encouraged to have preconception counseling.
