BACKGROUND: The Internet may serve as a suitable environment for discriminated adolescents as they may consider the online space as the place where they have possibility to build social ties they are missing in their offline life or manage their self-presentation. Therefore, our aim was to explore the association between different types of discrimination by peers (because of gender, physical appearance, culture/skin color/language, unfavorable family situation) and excessive Internet use (EIU), and whether gender moderates this association. METHODS: We used data from a representative sample of 6,462 Slovak adolescents (mean age: 13.00, 49.6% boys) from the HBSC study conducted in 2018. Data were collected through online self-reported questionnaires. We assessed the association between various types of discrimination by peers and EIU using linear regression, and the role of gender as potential moderator. RESULTS: Discrimination because of physical appearance was most prevalent (18.0%). Adolescents exposed to discrimination by peers reported higher levels of EIU. We found an interaction of gender on the association of discrimination because unfavorable family situation with EIU. Boys who experienced this type of discrimination were at higher risk of EIU compared to girls. CONCLUSION: Discriminated adolescents are more likely to use the Internet excessively, with some associations being stronger for boys than for girls. Prevention strategies focused on raising adolescent awareness of the risks and benefits of the Internet should target discriminated adolescents, especially boys, as they seem to be the vulnerable group.

Research of face-to-face meetings between adolescents and people met online stands on untested assumptions that these meetings are uniform, and adolescents attend them to expand their social circle. It is also unclear what makes such meetings pleasant or unpleasant. This study examined meetings of 611 Czech adolescents (age 11-16, Mage = 14.04, SD = 1.67, 47.1% female). Face-to-face meetings attended with friendly, romantic, or instrumental motives differed from each other, emphasizing the need to investigate them separately. Pleasantness of meetings is closely related to disconfirmation of adolescents' expectations. Unmet expectations related to unpleasant meetings, exceeded expectations to pleasant ones. While present findings uphold existing theories (e.g., social compensation), they also call for new theoretical perspectives for this common adolescents' activity.

OBJECTIVES: The overall aim of the research is to gain insight into the lifestyle and health behaviour of young people with disabilities aged 12-18 years, and to learn about the factors shaping their health. In this study, our aim was to investigate the eating habits and physical activity of adolescents with disabilities and the influencing factors. METHODS: The study's source population was young people aged 12-18 with disabilities in the Szabolcs-Szatmár-Bereg County. A total of 239 completed questionnaires were processed and analysed. Boys were overrepresented in the study. RESULTS: The results show that inadequate eating habits also exist in the population we studied, the consumption of certain foods correlates with the education level of parents. A more secure social background is a protective factor in terms of physical activity. The survey was made with the aim of intervention much needed. With precise knowledge of the health behaviour of the target group, our goal is to develop a complex intervention programme adapted to the needs of children with disabilities. CONCLUSION: The eating habits of adolescents with disabilities in the Szabolcs-Szatmár-Bereg County are unsatisfactory. Experience and results show that differentiated health promotion of young people with disabilities is necessary.

OBJECTIVE: The objective of the study, which consisted of a motivational lecture and hands-on training, was to evaluate the role of oral hygiene education for adolescents. METHODS: The study population included sixty-two high school students between fourteen and fifteen years of age (thirty males and thirty-two females). The response rate was 76.5%. The measurement of oral hygiene level was performed using the modified Green Vermilion Index (GVI). The values were recorded at baseline, one week, three months, and six months after education through motivational lecture and hands-on training was performed. Descriptive and nonparametric statistical methods were used in statistical analysis. Level of significance was 0.05. RESULTS: At the beginning of the study, the GVI of all examined subjects was 3.52 (SD = 0.70). One week after the motivational lecture and training, it decreased to 2.64 (SD = 0.69). Three months later, the level of plaque index had the lowest value (1.44; SD = 0.66). At the end of the study the level of plaque index increased to 2.52 (SD = 0.86). CONCLUSIONS: A significant oral hygiene improvement in adolescents as a result of education was presented. However, due to a decline in oral hygiene level six months after the education, there is a need for educational programmes continuity.

The incidence of venous thromboembolism (VTE) during childhood is low with two peaks - neonatal and adolescent age. This retrospective study is focused on clinical characteristics ofVTE during adolescence. The main goals are to assess the most frequent inherited and acquired risk factors and to evaluate the benefit of D-dimers in diagnostics of venous thromboemblism. The data of 18 adolescents were analysed--16 girls (88.9%), 2 boys (11.1%). In 9 patients (50%) thrombosis of the lower limb deep veins was diagnosed, six patients (33.3%) suffered from symptomatic pulmonary embolism (PE) and 3 patients (16.7%) from thrombosis at unusual sites. One patient had an idiopathic VTE, the mean number of the inherited and acquired risk factors was 2.6. The most frequent inherited risk factor was Leiden mutation of factor V (27.8%). The most frequent acquired risk factor was oral contraception (OC) in 12 out of 16 girls (75%). All of our patients on oral contraception had one or more additional risk factors. 10 out of 18 (55.6%) patients with VTE had elevated activity of factor VIII. The sensitivity of D-dimers was low (50%) in patients with distal lower limb thrombosis, but very high (100%) in patients with PE.

Research in some religious countries shows that religiosity and spirituality positively affect adolescent health. We studied whether religiosity and spirituality also have positive associations with adolescent health in a secular country. We tested the associations between religious attendance and spirituality and self-reported health and health complaints using a representative sample of Czech adolescents (n = 4182, 14.4 ± 1.1 years, 48.6% boys) from the 2014 health behavior in school-aged children (HBSC) study. We used religious attendance, the adjusted shortened version of the spiritual well-being scale (SWBS), and its two components-religious well-being (RWB) and existential well-being (EWB)-as independent variables and the eight item "HBSC symptom checklist" and self-reported overall health as dependent variables. A higher level of spirituality was associated with lower chances of health complaints and self-reported health, ranging from a 9% to 30% decrease in odd ratios (OR). Religious attendance was not associated with any of the observed variables. The EWB showed a negative association with all of the observed variables, with associations ranging from a 19% to 47% decrease. The RWB was associated with a higher risk of nervousness (OR = 1.12), while other associations were not significant. Non-spiritual but attending respondents were more likely to report a higher occurrence of stomachache (OR = 2.20) and had significantly worse overall health (OR = 2.38). In a largely secular country, we found that spirituality and the EWB (unlike religious attendance and the RWB) could have a significant influence on adolescent health.

Background: Overweight and obesity are mostly monitored via the Body Mass Index (BMI), based on self-reported or measured height and weight. Previous studies have shown that BMI as a measure of obesity can introduce important misclassification problems. The aim of this study was to assess the validity of overweight and obesity classification based on self-reported and on measured height and weight versus the proportion of body fat as the criterion. Methods: We used data on 782 adolescents (mean age = 13.5, 55.8% boys) from the Health Behaviour in School-Aged Children (HBSC) study conducted in 2018 in Slovakia. We obtained self-reported (height and weight) and objective measures (height, weight) and the proportion of fat (as the criterion measure) measured via bioimpedance body composition analysis (BIA) with an InBody 230 from the adolescents. Results: Both measured and self-reported BMI indicated overweight and obesity with relatively low sensitivity (66-82%), but high specificity (90-92%). The superior accuracy of measured BMI in comparison to self-reported BMI was confirmed by the area under the curve (AUC) based on the receiver operating characteristics (ROC) curves (AUC measured/self-reported: 0.94/0.89; p < 0.001). The misclassification of overweight and obesity was significantly higher when using self-reported BMI than when using measured BMI. Conclusion: Both self-reported and measured BMI as indicators of overweight and obesity underestimate the prevalence of adolescents with overweight and obesity.

BACKGROUND: Physical activity (PA) in adolescence is crucial for lifelong healthy lifestyle, and attention is needed to adolescents at health risk due to insufficient PA. This study investigates the composition of weekly PA in adolescents by PA level and provides a rationale for change in their lifestyles. METHODS: The research was conducted at 66 schools in Poland between 2009 and 2016, among 949 girls and 650 boys aged 15-18 years. We used pedometers to monitor weekly PA with data assessed using the Indares web app. The participants were split into three groups by mean daily step count (lower, < 9000; middle, 9000-12,999; and higher, ≥ 13,000 steps/day), as a reliable and non-expensive indicator of PA. RESULTS: We did not observe statistically significant differences in composition of 7-day PA between participants with varying levels of PA, regardless of their gender (F(12,9558) = 0.60; p = 0.841; ηp2 > 0.000). The smallest differences in daily step counts by PA level were found on Mondays and the biggest on Fridays and Saturdays, in boys and girls; the differences between average school and average weekend days were most pronounced in less active girls (1677 steps/day) and boys (1886 steps/day). During the school week, the highest proportion of less active girls met the 11,000 steps/day recommendation on Fridays (21.9%), statistically significantly less than on other school days (p < 0.001). Similarly, less active boys (22.2%) had significantly less activity on Fridays than on other school days, except for Mondays (p = 0.143) Analogous pattern was apparent also in more active adolescents. CONCLUSIONS: Less active adolescents have comparable composition of weekly PA to the more active ones but they can hardly meet the generally accepted PA recommendations. Better understanding of weekly PA composition and rates of meeting PA recommendations by day of the week can lead to more efficient interventions improving lifestyles. The recommendation of 9000 steps/day most days of the week, thus, appears appropriate for less active adolescents, as a motivating achievable goal.

AIM: This study aimed to evaluate the prevalence of overweight and obesity derived from measured data of weight and height in a cross-sectional sample of adolescents in the Italian region of Lazio and to analyse their association with different socio-demographic factors. METHODS: The study was conducted in a representative sample of 15-16-year-old adolescents recruited in secondary schools between December 2011 and May 2012. 369 adolescents were investigated. Body weight, height and waist circumference were measured. The BMI of each subject was calculated, and the prevalence of overweight and obesity was determined by age and sex using the IOTF reference values and WHO growth standards. Waist circumference/height ratio (WC/Ht) was calculated and the subjects were classified using the cut-off of 0.5: WC/Ht≥0.5 and WC/Ht<0.5. Selected socio-demographic characteristics were assessed via questionnaire. RESULTS: The percentages of overweight and obesity were high, 15.4% and 7.9%, respectively, with significant difference between males and females (19.1% vs. 12.6% for overweight and 11.1% vs. 5.3% for obese) using the IOFT reference. The ratio WC/Ht≥0.5 was observed in 12.7% of the sample (all the obese and 29.8% of the overweight subjects). Multiple logistic regression analysis indicated that gender, school municipality, mother's employment status, and family structure had a significant effect on ponderal status (overweight/obesity vs. normal weight). CONCLUSION: These findings show a high prevalence of body weight excess associated with socio-demographic factors in the Italian sample investigated, and the need for effective public health interventions to combact obesity with particular attention to disadvantaged adolescents.
