Objective The lack of a widely accepted questionnaire used to assess the physical activity (PA) of adolescents in the Polish language creates a need to introduce such a valid, reliable, inexpensive and quick tool for assessment. This study was designed to culturally adapt and validate the Physical Activity Questionnaires for Adolescents (PAQ-A) in the Polish language. Design Cross-sectional study. Participants and outcome measures Cultural adaptation of the Polish version of the PAQ-A was performed following the standardised questionnaires cultural adaptation process. In a sample of 78 adolescents aged 14–19 years, the PAQ-A test–retest was administered within a 1-week interval. Reliability was analysed by the intraclass correlation coefficient (ICC) and internal consistency with Cronbach’s α. Participants completed the PAQ-A, and wore an accelerometer for 7 consecutive days. The PAQ-A was compared with PA parameters obtained using the accelerometer. Results Test–retest reliability showed ICC=0.97 for the total score of PAQ-A. Internal consistency was excellent (α=0.93). The PAQ-A was very strongly correlated with steps per day (r=0.94) and with moderate-to- vigorous PA (r=0.81) assessed by the accelerometer. Conclusions The Polish version of the PAQ-A is a valuable tool to estimate general levels of PA among adolescents from 14 to 19 years old.

(Wydawnictwo Uniwersytetu Rzeszowskiego, 2017) Lintowska, Agnieszka; Mazur, Artur
Introduction. In today’s world, tobacco is the most common cause of morbidity and mortality and is associated with unhealthy behavior. Poland is among the countries with high rates of smoking, and occurrence of tobacco related diseases. Tobacco use by children and adolescents is a serious public health problem because of the immediate and long-lasting harmful effects on health. A large group of current smokers begin smoking during youth. The goal of the work was to culturally and linguistically adapt, and test and pre-evaluate a Polish version of the National Youth Tobacco Survey (NYTS), which identifies and monitors trends in tobacco use among young people. Materials and methods. The test was administered by a test-retest method in 2015 with participation of 47 (25 girls and 22 boys) people aged 17–18. Respondents filled out the questionnaire twice within two weeks. The compliance percentage of individual test items and correlations between individual items in repeated measurements were evaluated. Results. More than seventy percent have reliability ratios at very high or high levels with twenty five percent at moderate levels. Conclusion. The tested Polish version of the NYTS questionnaire may be used in adolescent studies.

(Wydawnictwo Uniwersytetu Rzeszowskiego, 2019) Przysada, Grzegorz; Guzik, Agnieszka; Wolan-Nieroda, Andżelina; Przybyło, Magdalena; Drużbicki, Mariusz; Mazur, Artur
Introduction. Cerebral palsy (CP) is a problem presenting multiple issues and the prevalence of this condition is quite significant. CP risk factors are mainly observed in prematurely born children as well as those affected by complications around the time of birth or during the period of mother’s pregnancy. Quite frequently CP is manifested by abnormal muscle tone, contractures and deformities, and consequently impaired fine and gross motor functions. Aim. The study was designed to examine the level of hand function, i.e. fine motor skills and to investigate whether there is a correlation between development of fine motor and gross motor functions. Material and methods. The study group included 80 children with infantile CP. In the group there were 24 cases with spastic diplegia, 36 with spastic hemiplegia, and 20 with bilateral hemiplegia. During the study the children performed Box and Blocks test, and their parents filled in Manual Ability Classification System (MACS) describing the level of fine motor function development in their children. The children were additionally asked to perform two motor tasks. The first one involved an attempt to assume position on all fours, and the other one checked the ability to assume and maintain standing position. Results. The best scores in the conducted tests were found in children with CP taking the form of spastic diplegia, and the poorest scores in MACS, Box and Blocks test as well as in motor tasks assessing gross motor function were observed in children with bilateral hemiplegia. Conclusion. The form of infantile CP affects the level of manual abilities. There is a correlation between the level of gross motor and fine motor functions development.

(BMJ Open, 2021-01-10) Wyszyńska, Justyna; Matłosz, Piotr; Asif, Muhamed; Szybisty, Agnieszka; Lenik, Paweł; Dereń, Katarzyna; Mazur, Artur; Herbert, Jarosław
Objective Associations between self-reported sleep duration and obesity indices in children are well recognised; however, there are no studies on associations between objectively measured other sleep parameters and physical activity with body composition in preschoolers. Therefore, the aim of this study was to determine the associations between sleep parameters and moderate-to- vigorous physical activity (MVPA) with body composition indices in preschoolers using objective measures. Design A cross-sectional study. Participants The study group consisted of 676 children aged 5–6 years, who were enrolled in kindergartens in the 2017/2018 school year. Outcome measures Sleep parameters and MVPA were measured using accelerometers for 7 days. Bioelectrical impedance analysis was used to estimate body composition. Results Sleep duration and sleep efficiency were inversely associated with body fat percentage (BFP) (β=−0.013 and β from –0.311 to −0.359, respectively) and body mass index (BMI) (β from −0.005 to −0.006 and from −0.105 to –0.121, respectively), and directly associated with fat-free mass (FFM) (β from 0.010 to 0.011 and from 0.245 to 0.271, respectively) and muscle mass (β from 0.012 to 0.012 and from 0.277 to 0.307, respectively) in unadjusted and adjusted models. BFP was inversely associated with MVPA and positively associated with number of awakenings and sleep periods. Number of sleep periods was inversely associated with FFM, and positively with BMI and muscle mass. Correlation matrix indicated significant correlation between BFP, FFM and muscle mass with sleep duration, sleep efficiency, number of sleep periods and MVPA. Conclusions Periodic assessment of sleep parameters and MVPA in relation to body composition in preschool children may be considered, especially in those who are at risk for obesity.

(2018) Więch, Paweł; Bazaliński, Dariusz; Binkowska-Bury, Monika; Korczowski, Bartosz; Mazur, Artur; Dąbrowski, Mariusz
Objective. The aim of this study was to assess the body composition and nutritional status of children and adolescents with newly diagnosed type 1 diabetes by using bioelectrical impedance analysis (BIA) with phase angle (PA) calculation. PA is considered to be the most sensitive indicator of the nutritional and functional status and it has not been evaluated in such population yet. Research Design and Methods. 63 children and adolescents aged 4 to 18 years, with newly diagnosed type 1 diabetes, were included in the study. Control group consisted of 63 healthy children and adolescents, without diabetes or other chronic disease having impact on the nutritional status, strictly matched by gender and age in a 1:1 case-control manner. In both groups a BIA was performed and PA was calculated. Results. Diabetic patients had highly significantly lower PA, 4.85 ± 0.86 vs. 5.62 ± 0.81 respectively, P<0.001 compared to control subjects. Also lower percentage of body cell mass (BCM%), 46.89 ± 5.67% vs. 51.40 ± 4.19% respectively, P<0.001, lower body cell mass index (BCMI), 6.57 ± 1.80% vs. 7.37 ± 1.72% respectively, P=0.004 and lower percentage of muscle mass (MM%), 44.61 ± 6.58% vs. 49.40 ± 7.59% respectively, P<0.001, were found in diabetic group. Conclusions. The lower PA score together with lower MM%, BCM% and BCMI in diabetic patients indicate their worse nutritional and functional status compared to healthy subjects. To assess the predictive and prognostic value of these findings further prospective studies in this population are required.
Evaluation of food offered in schools and bought by students in Rzeszów
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2018) Momora, Agnieszka; Mazur, Artur; Dereń, Katarzyna
Introduction. According to epidemiologic research, the number of obese and overweight children is increasing. A common way of dealing with this problem is enacting legislation regarding food served in educational institutions. In Poland, the regulations regarding the assortment of school shops are contained in the Ordinance of the Minister of Health of 26th June 2015 (and its subsequent amendments). Aim. The main aim of this study is to evaluate the product range of school shops and vending machines in Rzeszów. Methods and materials. The study covered 52 primary and secondary schools in Rzeszów. The schools included in the study had 15568 students altogether. Products bought by students in school shops and vending machines were recorded over the period of 3 days. Results. The study has shown a statistically significant relationship (p <0.001) between the amount and types of products bought in primary and secondary schools. Healthy snacks only made up a small percentage of products sold. Secondary schools sold 20% more snacks with high sugar content compared to primary schools. A majority of products sold were compliant with regulations (p=0.12). Conclusions. The assortment of school shops has changed after the implementation of the Ordinance of the Minister of Health of 26 June 2015 (and its subsequent amendments). The newly introduced restrictions significantly narrowed down the range of products offered in schools, reducing the number of products containing more than 15g of sugar (13.5g per 100g/ml in case of dairy products) or 10g of fat per portion.
Excessive body mass and its correlation with hypertension – a review of the literature
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2016) Wyszyńska, Justyna; Podgórska-Bednarz, Justyna; Mazur, Artur
Hypertension is a serious health issue both in Poland and worldwide. It has been demonstrated that hypertension diagnosed in childhood persists in adulthood. Therefore, knowledge of the risk factors, prophylaxis and treatment of hypertension are crucial due to its serious medical and social consequences. Early identification of risk factors for hypertension allows to implement targeted preventive actions leading to the modification of habits connected with lifestyle, which in turn may lead to a reduction in the incidence of the disease or reduce its effects. The aim of the paper is to characterize the relationship between the occurrence of excessive body mass and hypertension in adults and in children and adolescents. Material and methods. A review of Polish and foreign literature mainly from the last 10 years. The following databases were searched: PubMed, EBSCO, Science Direct, Termedia, Polish Medical Bibliography.
Glycosylation of immune system proteins and its role in autoimmune diseases and cancer
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2020) Trzyna, Anna; Tabarkiewicz, Jacek; Mazur, Artur
Introduction. Structural glycans have great biological significance and are involved in signaling and cell communication of the immune system. They are attached to proteins and lipids in an enzymatic process called glycosylation where glycosyltransferase and glycosidases bind sugar residues and lead to the formation of bioconjugates. Aim. In this paper we describe the importance of glycosylation in the immune system and its changes in diseases. Material and methods. This review was performed according to systematic literature search of major bibliographic databases. Results. Proper glycosylation ensures the functioning of the organism, however, defects in structural glycans of immune system changes their properties and can lead to disorders and further to autoimmune diseases. It has been also proven that glycosylation of autoimmune system is changed during cancer. In this paper we described types of structural glycans, significance of glycosylation of selected components of the immune system and its modifications in disorders. Conclusions. Knowledge about changes in the glycosylation in diseases is the key to understanding the processes of autoimmune diseases and may allow the development of new treatments in the future.
Obesity and Body Composition in Preschool Children with Different Levels of Actigraphy-Derived Physical Activity—A Cross-Sectional Study
(Journal of Clinical Medicine, 2020-04-23) Wyszyńska, Justyna; Matłosz, Piotr; Szybisty, Agnieszka; Lenik, Paweł; Dereń, Katarzyna; Mazur, Artur; Herbert, Jarosław
Detailed associations between physical activity (PA) and body composition in preschoolers remain unclear. The aim of this study was to assess body composition among preschool children differentiated according to their levels of PA and to assess whether meeting the current PA recommendations is associated with a lower risk of obesity, determined by body mass index (BMI) and body fat percentage (BFP). Free-living PA was measured using accelerometers for 7 days in children aged 5 to 6 years. Bioelectrical impedance analysis was used to estimate body composition. Significant differences in content of BFP, fat-free mass (FFM), and total body water (TBW) were found between boys meeting and not meeting moderate-to-vigorous PA (MVPA) recommendations. Meeting the MVPA recommendation was associated with a twofold lower risk of obesity determined by BFP in boys but not in girls. In contrast, the total number of recommended steps per day was not related to adiposity in boys or girls. No statistically significant differences were observed in body composition indices and quintiles of MVPA. Boys in the 3rd–5th quintiles of steps per day presented significantly lower BFP and higher muscle mass and TBW than their peers in quintile 1. However, different associations were observed between body composition indices and quintiles of PA.

(Wydawnictwo Uniwersytetu Rzeszowskiego, 2018) Dereń, Katarzyna; Jarmakiewicz, Sara; Sokal, Aneta; Łuszczki, Edyta; Motyka, Elżbieta; Wyszyńska, Justyna; Kowal, Regina; Mazur, Artur
Introduction. In recent years there has been a significant increase in the prevalence of overweight and obesity in humans. It turns out that the problem is not limited to adults; excessive body weight is occurring in children more often. Aim. The main purpose of this work was to determine the prevalence of overweight and obesity in preschool children from the Rzeszów district, and to determine risk factors for occurrence. Materials and survey method. The study was conducted among 200 preschool children (3 - 6 years of age) from the Rzeszów poviat area. Measurements of height, weight, and determination of BMI were performed and these values are standardized according to the WHO centile grids appropriate for each age group. Survey results. Normal weight was observed in 58% of the respondents, 11% were overweight, and 10.5% were obese, whereas 20.5% of children had undernourishment. Obese children were the largest group among 6-year-olds. Among 4 year old children, abnormal body weight were more frequent in boys. On the other hand, in children aged 5 years, undernourishment or overweight was found more frequently in girls. Conclusions. The study did not confirm a significant relationship between gender, place of residence and socio-economic situation of respondents, and the prevalence of overweight or obesity. The results of this study indicate that the problem of excessive body weight refers to the increasing number of children.
Risk factors for overweight and obesity in pre-school children
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2018) Polak, Ewelina; Dereń, Katarzyna; Łuszczki, Edyta; Wyszyńska, Justyna; Piątek, Adriana; Mazur, Artur
Introduction. Obesity in children and adolescents is a growing problem in the 21st century. The epidemic of chronic non-communicable diseases resulting from obesity is currently one of the biggest problems of modern medicine. Excessive body weight is the result of a long-lasting imbalance between the amount of energy supplied and its expenditure. Energy regulation of the body is subject to both genetic and environmental factors. Among other things, due to this, the problem of excessive body weight is most severe in societies with a high degree of socio-economic development. The aim of this paper is to determine the influence of selected environmental and social factors on the occurrence of overweight and obesity in pre-school children. Material and methods. The study included pre-school children from south-eastern Poland. After obtaining the consent from parents, 200 children (87 boys, 113 girls) aged 3 to 6 years were examined. A questionnaire used for the research was derived from the program: European Pilot Study Evaluating the Influence of Local Promotional Activities on Prevention of Obesity in Pre-school Children. In the subjects, body weight was measured on an electronic scale three times and the body height was measured three times using a stadiometer. Obesity was determined according to the criteria developed by the International Obesity Task Force (IOTF). Results. The prevalence of overweight and obesity among children amounted to 6.4% in 3-year-olds, 11.3% in 4-year-olds, 17.7% in 5-year-olds, and 20.7% in 6-year-olds. A factor significantly increasing the risk of obesity among the examined girls and boys was the mother’s BMI index. Conclusion. Although knowledge about the factors that promote overweight and obesity is common, it is still a common health problem. Particular attention should be paid to the prevention of obesity in children of parents with a BMI above 30 kg m2. Early maternal education can change the lifestyle of the whole family.
Selected factors influencing the level of physical activity in the elderly
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2018) Wyszyńska, Justyna; Dereń, Katarzyna; Hausner, Iwona; Mazur, Artur
Introduction. It is commonly known that physical activity has great influence on the quality of life and health in the people of all age groups. Physical activity has a beneficial influence on both functional and locomotive abilities, the dynamics of which deteriorates during the process of aging, and this in turn has an impact upon satisfaction of basic biological, social and psychological needs. Aim. The main purpose of this study was an assessment of selected factors affecting the level of physical activity in the elderly. Material and methods. The study group consisted of 100 participants (85 women and 15 men), aged from 65 to 69 years old. An International Physical Activity Questionnaire (IPAQ) - Polish long version was used. Results. A high level of physical activity was reached by 44 participants, moderate level of physical activity was noted in 53 participants, and low in physical activity was found in 3 participants. Older the subjects reached lower MET value in case of job-related physical activity and higher MET value in case of physical activity in free time and total intense effort. Conclusion. The level of job-related physical activity, the level of physical activity in free time and the total intense level of activity depended on the age of the subjects. There were no association between the level of total physical activity and sex, place of residence and BMI of participants.
The association of actigraphic sleep measures and physical activity with excess weight and adiposity in kindergarteners
(Scientific Reports, 2021-01-27) Wyszyńska, Justyna; Matłosz, Piotr; Szybisty, Agnieszka; Dereń, Katarzyna; Mazur, Artur; Herbert, Jarosław
Insufficient sleep duration and physical activity (PA) are known risk factors for overweight and obesity in children; however, there are no studies on comprehensive associations of objectively-measured sleep parameters and PA with excess weight and excess adiposity in kindergarteners. Therefore, the aim of this study was to determine the associations between objectively measured sleep parameters and PA with excess weight and excess adiposity, defined as BMI ≥ 85th percentile and body fat percentage (BFP) ≥ 85th percentile, respectively. Sleep parameters and PA were measured in 676 subjects aged 5–6 years using accelerometers for 7 days, worn at the participant’s hip. Bioelectrical impedance analysis was used to estimate BFP. In the total sample, lower sleep duration, sleep efficiency, vigorous PA and the number of steps per day were associated with excess weight. However, excess adiposity was associated with lower sleep duration, total PA, vigorous PA, moderate-to-vigorous physical activity (MVPA) and the number of steps per day. Logistic regression by the stepwise progressive method showed that the strongest predictor of excess adiposity in boys and girls was vigorous PA, while the strongest predictor of excess weight in boys was sleep efficiency. A holistic approach to health targeting all of these factors synergistically is needed to optimize the effectiveness of obesity prevention and treatment interventions.

Otyłość wśród dzieci i młodzieży jest coraz większym problemem zdrowotnym w XXI wieku. Reklamy żywności o wysokiej wartości energetycznej i ubogiej w składniki odżywcze mogą wpływać na wybory konsumentów. Celem badania była analiza wartości kalorycznej wszystkich reklamowanych produktów żywnościowych, skierowanych do dzieci w trzech stacjach telewizyjnych. Metody: Nagrano wszystkie programy emitowane w trzech kanałach telewizyjnych (TVP1, Polsat, Cartoon Network), w ciągu czterech dni każdego tygodnia (przez okres od września do października). Emitowane reklamy zostały przeanalizowane w celu określenia liczby reklamowanych produktów żywnościowych. Następnie zakupiono reklamowane produkty i obliczono ich wartość energetyczną. Wyniki: Średnia wartość kaloryczna reklamowanych produktów żywnościowych, skierowanych do dzieci wahała się od 1700 kcal/ dzień w stacji Cartoon Network do 33000 kcal/ dzień w telewizji Polsat. Reklamowaną żywność stanowiły głównie przekąski i produkty typu fast-food, o wysokiej zawartości tłuszczów i cukru. Średnia wartość kaloryczna reklamowanego produktu żywnościowego wyniosła 500 kcal na 100g. Wnioski: w reklamach telewizyjnych skierowanych do dzieci, promuje się głównie żywność o wysokiej wartości energetycznej, ubogą w składniki odżywcze. Taka promocja może wpływać na zachowanie konsumentów i tym samym wpływać na nadmierne spożycie wysokokalorycznych produktów żywnościowych.

(Wydawnictwo Uniwersytetu Rzeszowskiego, 2016) Weres, Aneta; Baran, Joanna; Łuszczki, Edyta; Dereń, Katarzyna; Mazur, Artur
Introduction. A severe epidemic of lifestyle diseases, including obesity, is now one of the biggest problems of modern medicine. This is a medical problem, social and economic. The purpose of this study was to determine the impact of selected perinatal and environmental factors on the prevalence of overweight and obesity in preschool children located in the Subcarpathian region. Materials and methods. The survey was conducted in 2012, it included 200 children between the ages of 3 to 6 years (87 boys and 113 girls) from kindergartens. In children, weight loss was measured on an electronic balance and their height was also measured on medical scale. Obesity was determined on the basis of criteria developed by the International Obesity Task Force (IOTF). Results. The prevalence of overweight and obesity among preschool children was found in 3-year-olds (6.4%), 4-year-olds (11.3%), 5-year-olds (17.7%), and 6-year-olds (20.7%). Conclusions. Body weight and mother’s BMI are factors that significantly increase the risk of obesity among children aged 3–6. Additionally, in boys, a risk factor is also the birth body length.
