Pregnancy is an important period in a life of a woman and her family, which is followed by a series of physiological changes. An optimal nutritional status contributes to the preservation of the mother's health and prevents the development of fetal defects. The aim of this paper was to examine the knowledge and attitudes of women in the Dubrovnik-Neretva County on the importance of proper nutrition during pregnancy. 150 women voluntarily participated in the research, filling out a questionnaire related to the mentioned topic. The results showed that 44% of pregnant women gained an optimal 10-15 kg by the end of pregnancy, and 11% gained more than 20 kg. 77.3% of them follow the recommendations on the use of dietary supplements, and 94.7% of them believe that proper nutrition is important during pregnancy. Most of them partially changed their eating habits. Only 32% of respondents stated that they received information about healthy eating from health care professional, and 84% of them believe that they should provide special education on the mentioned topic. As a conclusion of the research, it can be said that attitudes about the importance of proper nutrition during pregnancy among women in Dubrovnik-Neretva County are positive, but health care professionals, including nurses, should be better educators in this area.
