Obesity is a serious health problem in nearly all regions of Europe. During the last four decades, the percentage of obese people increased four times among men and twice among women, reaching a global epidemic scale as the biggest health-related issue in the developed and developing countries. The aim was to assess the epidemiological situation of obesity, according to gender among adults in Europe, compared with other regions and selected worldwide countries, as well as to devise a forecast for the near future based on analysis results. An overview was performed of the World Health Organization (WHO) statistical database in 1999-2016, concerning obesity prevalence among people over the age of 20 across 28 countries of the European Union. A forecast for the years 2020 and 2030 was prepared by evaluation of gradients for trendline equations. Moreover, some of the world regions, as well as individual countries, five per region, were collated and analyzed to prepare the forecast. The percentage of obese people in the countries of the European Union continues to increase every year. The dynamics of obesity growth in Europe is greater for men than for women (3.09% per year vs. 1.92% per year). With the growth rate remaining at the estimated level, in 2030 there will probably be more obese men (38.1%) than women (32.7%) in Poland, and in Europe likewise - 36.6% and 32.0%, respectively. Obesity has become a major epidemiological problem and an undisputable health problem not only in Poland and other European countries, but worldwide.

Background: The aim of this study was to examine adolescents’ perceptions of parental, teacher, and peer support for physical activity, and to examine the associations between these perceptions and physical activity behavior. Methods: The study included 902 secondary school students, who completed the Short Scale of Youth’s Social Support Assessment (SSYSS). The level of physical activity – more specifically, moderate to vigorous physical activity – was measured using a Physical Activity Screening Measure. The associations were examined by a five-step hierarchical regression. Body mass index (BMI) was defined using the LMS method, which summarizes the distribution of BMI by age and gender in terms of three curves, L (lambda), M (mu), and S (sigma), and was based on a nationally representative sample of Polish children and adolescents. Results: The study indicated a positive correlation between MVPA (moderate to vigorous physical activity) and three sources of social support; however, in the regression model, this explained only part of the variance. In the hierarchical multiple regression analysis, MVPA level was predicted by five variables involvement in sports training, teachers support, parents support, gender and BMI. The direct effects for teachers and parents support were similar. This demonstrates that both teachers’ and parents’ social support exert influence on adolescent MVPA. Conclusions: The findings from this research suggest that school-based interventions for adolescents should specifically take into consideration family, teachers, and peers as important sources of social support for general physical activity promotion that aims to increase its levels.

This study aimed to compare physical activity (PA) levels before and during a pandemic lockdown among adolescent Polish youths in relation to meeting the World Health Organization’s (WHO) recommendations of moderate-to-vigorous physical activity (MVPA) and identify potential environmental factors that may affect these levels. An online survey tool that included validated measures of adolescents’ MVPA and socio-environmental, potential confounders was administered to youths (e.g., lack of classmates, motivation, possibility of choosing any physical exercise time, possibility of choosing your own exercises, home environment). The analytic sample comprised 127 adolescents aged 15.4 ± 0.5 years on average (52% girls and 48% boys). The results highlight that among adolescents who did not meet the WHO MVPA recommendations before the lockdown, 13.4% had an increased frequency of PA (from 2.9 to 5.4 day/week) (p = 0.01) during the lockdown. In the group who did meet these recommendations before the lockdown, 50% significantly decreased their level of MVPA below the WHO’s recommendations (p = 0.01). Self-rated health for PA showed a significantly strong correlation with MVPA in the group of students who met the WHO recommendations before the pandemic (r = 0.76; p < 0.05) but failed to maintain that recommendation during the COVID-19 restriction. The results suggest a negative impact of the pandemic on PA undertaken by youths. Based on these results we see the need for increased action by both Physical Education (PE) teachers and parents to motivate and support youngsters in taking up systematic PA consciously.

The falling fertility indicators and high prevalence of infertility in Poland make it important for people of reproductive age to have good knowledge of their own fertility in order to be able to take care of their reproductive health. This paper examines reproductive health literacy and fertility awareness among Polish female students. It can help identify gaps in reproductive health education in Poland. The study group included 456 women aged 18–29, who were students of 6 public universities located in Poznan, Poland. The method used was a survey using a self-developed questionnaire assessing the students' knowledge of female and male fertility-related physiology and fertility patterns. The respondents' knowledge was assessed on the basis of the percentage of correct answers. Regression analysis and univariate analysis of variance were used to explore relationships between the students' knowledge and their age, year of study, university and source(s) of information. The average score of correct answers was 55.8%. Older students and medical university students were the most knowledgeable. 93.4% of the respondents correctly identified the optimum age for a woman to have the first child from the point of view of achieving pregnancy fast. Over 90% of the respondents knew such fertility-compromising risks as smoking, diseases and psychological distress. There was much poorer awareness of the adverse effect of unbalanced diet, irregular sleep, and long-lasting physical effort. 47.1% of the students reported gaining information from a number of sources, but as many as 28.3% said their only source was primary or middle school classes. Reproductive health knowledge among the young female students is incomplete, especially as regards lifestyle-related risks. They should be encouraged to supplement it by consulting reliable sources such as health professionals. It is advisable to ensure that the curricula of medical university students provide thorough knowledge in this area, and to arrange suitable electives for students from other universities. As primary and secondary school classes remain an important source of information, quality teaching at these levels should be offered with a focus on making the knowledge as practical and operational as possible. Relevant graduate, postgraduate and in-service courses should be available to professionals responsible for spreading reproductive health knowledge.

The purpose of this study was to evaluate the quality of implementation and Physical Education (PE) teachers’ perceived advantages, disadvantages, and encountered difficulties of online PE teaching during the first wave of the COVID-19 pandemic. The participants were 1148 professionally active PE teachers from Poland, North Macedonia, Croatia, Turkey, Bulgaria, and Kosovo (613 female, 535 male). A cross-sectional online survey study was performed between May and September 2020 and was done online through an electronic questionnaire. Study results suggest differences in evaluation of online teaching between PE teachers from different countries: a positive evaluation of online teaching reported from teachers from Croatia, Poland, and Bulgaria, neutral in Turkey, and a negative evaluation during that period by teachers in Macedonia and Kosovo. Different ratings of advantages, disadvantages, and difficulties from the studied countries in online teaching in primary and secondary schools were also noted. A lack of proper equipment at home, a lack of proper training for information technology (IT) use, as well as use of different platforms for online teaching were among the highest-ranked difficulties during online teaching. The greatest concerns during online PE teaching were identified in terms of pupils’ safety, the intellectual property of resources, and the quality of curriculum delivery. The results from the study identify the most important areas of teachers work where PE should be supported regarding online teaching.

Introduction: Apart from its medical dimension, the current problem with obesity has acquired social urgency. This serious lifestyle disease has a negative impact on a number of life processes in the body, causing distortions and damaging different structures. It also contributes to clinical...
