Physical and screen-based activity in adolescents plays a crucial role in future health outcomes. Therefore, the aim of the study was to examine the associations of physical activity and screen-based activity with behavioural and psychosocial characteristics of school-aged children. Data on 11, 13 and 15 years old elementary school pupils (N=9,014; mean age=13.59) who participated in the cross-sectional Health Behaviour in School-aged Children 2009/2010 study in the Czech Republic and the Slovak Republic were analyzed. The associations of vigorous physical activity and screen-based activity with substance use, violent behaviour, eating habits and school-related outcomes adjusted for age were explored using logistic regression. Vigorous physical activity was positively associated with some of the health-related behaviours (smoking, breakfast consumption, vegetable and fruit consumption) and school related outcomes (perceived school achievement and school pressure), with gender and co...

Roma are the most deprived ethnic minority in Slovakia, suffering from discrimination, poverty and social exclusion. Problematic access to good quality health care as result of institutional and interpersonal discrimination affects their health; therefore, factors which affect health care accessibility of Roma are of high importance for public health and policy makers. The aim of this study was to explore the association between health care accessibility problems and ethnicity and how different levels of social support from family and friends affect this association. We used data from the cross-sectional HepaMeta study conducted in 2011 in Slovakia. The final sample comprised 452 Roma (mean age = 34.7; 35.2% men) and 403 (mean age = 33.5; 45.9% men) non-Roma respondents. Roma in comparison with non-Roma have a more than 3-times higher chance of reporting health care accessibility problems. Social support from family and friends significantly decreases the likelihood of reporting hea...

The aim of this study is to determine to what degree antisperm allo-antibodies (ASA), anti-ovarian antibodies (AOA), anti-zona pellucida antibodies (AZPA) and seven anti-phospholipid antibodies (APLA) can explain the failure of assisted reproduction technology (ART) in women. Among the causes of reproductive failure are allo- and autoimmune reactions of the organism against reproductive tissues and cells. We examined a sample of 43 selected women aged 27 to 45 after failure of assisted reproduction technology (ART) via intrauterine insemination (IUI), in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). Sera from these women were tested by ELISA (enzyme-linked immunosorbent assay) (total Ig) for the presence of anti-sperm allo-antibodies (ASA), anti-ovarian antibodies (AOA), anti-zona pellucida antibodies (AZPA) and seven anti-phospholipid antibodies (APLA). We found 22 (51 %) patients positive for the examined antibodies. Among patients with positive results were 3 miscarriages, 3 biochemical pregnancies (↑ hCG) and 16 with no evidence of conception. Positive APLA was found in 17 patients. Selected immunological parameters were negative in 21 (49 %) patients, which means that the tested allo- and auto-antibodies did not cause the failure of ART. This demonstrates that the range of diagnostic tests limits the success of diagnosis and the method of dealing with infertile couples. The use of cardiolipin as a screening test appears to be insufficient, because in our sample it would have caused a 35 % error rate. Investigation of antibodies against seven phospholipids is thus considered to be reasonable and is beneficial for infertility diagnosis (Tab. 2, Ref. 36).

Better assessment of the reliability of the physical activity and sedentary behaviour items across countries in all WHO regions is highly needed. The aim of the study was to examine the test-retest reliability of selected physical activity and sedentary behaviour items of the HBSC questionnaire in Czech, Slovak and Polish adolescents. We obtained data from 693 Czech, Slovak and Polish (50.9 % boys) primary school pupils, grades five (mean age = 11.08; SD = 0.45) and nine (mean age = 15.12; SD = 0.45), who participated in a test-retest study in 2013. We used the single measures of Intraclass Correlation Coefficients (ICC) and Cohen's Kappa statistic to estimate the test-retest reliability of all selected items within the sample and stratified by gender, age group and country. Both physical activity items (VPA and MVPA) and most of the sedentary behaviour items showed moderate agreement (ICC 0.41-0.60) and a similarly moderate correlation (Cohen's Kappa 0.3-0.5) after dichotom...

Roma constitute a large minority in several Central European countries, with a mostly disadvantaged societal and health position. The aim of this study was to assess biological and other cardiovascular diseases (CVD) risk factors in people living in Roma settlements and to compare them with non-Roma. We used data from the cross-sectional Hepa-Meta study conducted in Slovakia. The sample consisted of 452 Roma (mean age = 34.7, 35.2 % men) and 403 non-Roma (mean age = 33.5, 45.9 % men). The effect of ethnicity was analysed using logistic regression adjusted for age and stratified by gender. Roma were more likely to have obesity, low HDL cholesterol, normal total cholesterol, and to smoke than non-Roma. Moreover, Roma women were more likely to have abdominal obesity and Roma men to have normal LDL cholesterol than non-Roma. No significant differences by ethnicity were found regarding hypertriglyceridaemia, hyperglycaemia and hypertension. Our study confirmed higher rates of some CVD risk factors in Roma compared with non-Roma. Our findings call for interventions aiming at decreasing CVD risks and improving health literacy among Roma, to reduce CVD morbidity and premature mortality.
