This research evaluated several selected elements of the lifestyle of pregnant women compared to those of non-pregnant women. Methods: Overall, 482 women attended to the Childbirth School in Gynecological-Obstetric Hospital “Inflancka” in Warsaw, Poland, in the years 2011-2013; Group 1 contained 214 pregnant, and Group 2 contained 268 non-pregnant completed a survey inquiry. The research tool applied was Juczyński’s “Inventory of Health Behaviour” (Inwentarz Zachowań Zdrowotnych). In this tool, the author evaluates health behaviors through four separate categories: dietary habits, prophylactic behaviors, mental attitude, and health behaviors. The differences between the data were defined through the Student’s t-test for independent groups, with a minimal level of significance set at P ≤ 0.05. Results: Pregnant women take care of following a healthy lifestyle. The general health behaviour index figure was significantly higher in Group 1 as compared with the Group 2 (P<0.001). A higher level (P<0.001) of healthy behaviour was typical of physically-active individuals, regardless of their Group (1 & 2). Conclusion: Pregnancy might cause women to increase their interest in matters of their own health and adopt a healthier lifestyle. Physical activity can influence other health-related practices.     https://ijph.tums.ac.ir/index.php/ijph/article/view/12046 https://ijph.tums.ac.ir/index.php/ijph/article/download/12046/5871
