Proper nutrition is essential for the health of every human being in the world. For decades, we have been working on various programs of education and encouragement for a healthy lifestyle, which includes a moderate and varied diet, intake of sufficient fluids and exercise. In pregnancy, these items are even more important because of the various changes that occur in order to enable the growth and development of the fetus, which is why the need for nutrients grows. This anonymous survey was conducted at the Clinic for Gynecology and Obstetrics of the University Hospital Center Rijeka, as a retrospective, on a sample of 40 midwives. The purpose of the study was to determine the knowledge and implementation of healthy habits in pregnancy. The results show that 62.50% of women entered pregnancy with normal weight, and the average body mass index was 24.44. According to the average gain of 15.9 kg, we conclude that it is not ideal for the average, but it is not too worrying either. Awareness of harmful habits is seen by the large difference among smokers before (55%) and during pregnancy (10%). 70% of respondents had the optimal number of daily meals (3-4), and drank enough fluids (77.50%) 2-5 liters, mostly water (95%). About half of the respondents (55%) exercised, mostly walking. They were educated via the Internet and other mothers, and from the health staff with a gynecologist and a community nurse. From the results it can be concluded that women are satisfactorily educated, but there is still work to be done, and for better performance to include midwives in education.
