This study explores the importance of nursing support in promoting the health of pregnant women before childbirth, focusing on the role of nurses in supporting nutrition, physical activity, medication use, complication prevention, breastfeeding, mental health, and overall maternal and child care during pregnancy. The role of nurses in promoting maternal health includes education, counseling, early problem recognition, and providing emotional support. Their multidisciplinary approach is crucial for optimizing health outcomes for mothers and children during pregnancy. This paper emphasizes the significance of continuous nursing support as a key factor in the healthcare system, encouraging further research and the implementation of practices aimed at improving care for pregnant women. The aim of the research was to assess the impact of nursing support on the health habits of pregnant women. It analyzed the relationship between the frequency and quality of nurse support and pregnant women's awareness of health recommendations and adherence to them during pregnancy. Additionally, it explored the connection between receiving support and pregnant women's residential location, as well as the perception of support quality and the educational level of pregnant women. Research results indicate a statistically significant correlation between the frequency of nursing support received during pregnancy and the awareness and adherence to recommended healthy habits among pregnant women. Those who received frequent support and advice from nurses were better informed and more likely to adhere to recommendations compared to those who received support infrequently or occasionally. Additionally, a statistically significant association was found between the educational level of pregnant women and their awareness of and adherence to healthy habits; pregnant women with lower educational levels were less informed and less likely to adhere to recommendations compared to those with higher education. Moreover, there was no statistically significant difference in the frequency of nursing support based on pregnant women's residential location (rural or urban areas), suggesting that the perception and frequency of support did not significantly differ among pregnant women residing in different types of areas. Consistent with the research findings, the role of nurses as a crucial source of support during pregnancy underscores the importance of continuous support and information for better health habits among future mothers.
