Objectives: Regular and moderate physical activity during uncomplicated pregnancy has been considered beneficial for both the expectant mother and her unborn child. It reduces the risk of gestational diabetes mellitus (GDM) and preeclampsia.The aim of the study was to assess women's knowledge concerning specific aspects of physical activity during uncomplicated pregnancy. Material and methods:A cross-sectional survey study on a sample of Polish women in a tertiary referral centre was performed. A questionnaire that was validated in the Polish language was based on the Committee Opinion of American College of Obstetricians and Gynaecologists, which was published in December 2015. Sociodemographic parameters in relation to specific aspects of physical activity during pregnancy were analysed.Results: A total of 259 (92.5%) women were aware of the beneficial impact of physical activity on the course of pregnancy. Higher education was associated with greater awareness (p = 0.001). Regarding the optimal frequency and recommended duration of exercise, the overall rates of correct answers were only 106 (38.1%) and 167 (59.6%), respectively. The most common sources of information on physical activity during pregnancy were the Internet (81, 50.0%) and books (62, 38.3%). Doctors and midwives instructed the respondents only in 36 (22.4%) and 31 (18.9%) cases, respectively.Conclusions: Women's knowledge about physical activity during pregnancy seems satisfactory. However, awareness concerning the optimal duration and frequency of exercise, as well as recommended voluntary activities during pregnancy, should be improved. Medical professionals may also reinforce their role as a provider of reliable information, resulting in the prevention of many pregnancy complications.

Introduction. Hyperthermia during the first trimester increases the risk of miscarriage and birth defects. A variety of activities predisposing to hyperthermia during pregnancy such as attending sauna, hot tubs or solarium may lead to irreversible abnormalities of the developing fetus.Aim. The aim of the study was to assess women's knowledge on the risks of maternal hyperthermia during each trimester of pregnancy.Material and methods. It was a cross-sectional study conducted by means of an anonymous questionnaire. The study group included 302 women aged 17-65 who were admitted to a tertiary referral hospital. The questionnaire was designed on the basis of the Committee Opinion formulated by the American College of Obstetricians and Gynecologists and was consisted of two sections: demographic data and respondents' opinions on activities associated with hyperthermia in pregnancy. Statistical analysis was conducted to estimate the association of age, level of education and obstetrical status.Results. The lowest percentage of given proper answers was observed in case of questions about early pregnancy. There was no association between respondents' level of education and choice of correct answers. Current pregnancy was associated with higher awareness of contraindicated using of hot tubs and steam rooms.Conclusions. Patients' education concerning hyperthermia in pregnancy should focus on information about high risk of birth defects caused by overheating in the early pregnancy and a variety of activities linked with temperature elevation.
