Introduction. Pregnancy is a unique period in a woman’s life, during which it is particularly important that she takes care of her health and makes informed decisions that are beneficial to both her and the child. Appropriate health habits can reduce the risk of complications and support the proper development of the child and the well-being of the mother. In this context, health education plays an important role, covering various forms of preparing for childbirth and motherhood, such as birthing classes, consultations with a midwife, or individual educational meetings. Participation in such classes promotes health awareness and beneficial health-related decisions during pregnancy. Aim. The aim of the study was to assess the health behaviours of pregnant women and to analyse the relationship between the level of health knowledge, participation in educational programmes, level of education, and the overall health behaviour index (IZZ) and sense of readiness for childbirth. Methods and materials. The study comprised 102 pregnant women. A standardised Health Behaviour Inventory (IZZ) questionnaire and a questionnaire developed by the authors were used to conduct the study. Results. A high level of health behaviours was observed in 60.8% of participants. Participation in educational programmes correlated significantly with a higher IZZ level (p = 0.002) and better eating habits (p < 0.001). Positive correlations were observed between the level of health knowledge and pro-health behaviours (rho = 0.42; p < 0.001) and between education and IZZ (rho = 0.38; p < 0.001). 97.1% of women indicated the need to include emotional aspects in health education. The main barriers to health care were lack of time and financial difficulties. Participation in educational classes had a positive effect on the sense of feeling prepared for childbirth (77.4%).
