3. Sexual health literacy among Slovenian secondary school students : a descriptive studyMarta Šporin, Tina Kamenšek, Marija Milavec Kapun, 2024, izvirni znanstveni članek Povzetek: Introduction: Sexuality education for adolescents is an important area of education. The aim of this study was to assess the knowledge of Slovenian upper secondary school students about sexuality, as well as their experiences, behaviours, and sources of information about sexuality. Methods: An invitation to complete an online questionnaire for first-year students was sent to all secondary schools in central Slovenia. The responses of 201 participants were included in the analysis. The average age of the respondents was 15.59 years; 57% of the participants were female and 67% attended general upper secondary school. The data were statistically analysed using chi-square, Mann-Whitney U, and t-test.Results: Respondents cited the internet (67.0%) and friends (60.4%) as the most common sources of information on sexuality. Most respondents expressed a preference for seeking information from healthcare professionals (61.2%) and least from teachers (26.5%). Sexual experiences involving vaginal penetration were found to be more frequent among students enrolled in vocational and technical education programmes than those attending general upper secondary education programmes (χ2 = 7.863, p = 0.005). Knowledge about sexuality was found to differ by gender (U = 2257.500, p = 0.003) and type of secondary school (U = 1943.500, p = 0.001). Knowledge about sexuality was positively associated with the frequency of discussions about various sex-related topics, with the exception of petting. It was, however, not associated with sexual activity or the use of protection.Discussion and conclusion: More attention needs to be paid to the provision of sexuality education for secondary school students. School nurses can promote information sharing among peers, empower parents to engage in discussions on these topics with their adolescent children, and provide sexuality education in the school setting. Our study findings on the effectiveness of different forms and contents of sexuality education can serve as a basis for enhancing the existing preventive programmes.

4. Health behaviour of adolescents in Slovenia : major results from 2010 and trends from 2002 to 2010Helena Jeriček Klanšček, Helena Koprivnikar, Maja Roškar, Tina Zupanič, 2014, izvirni znanstveni članek Povzetek: Introduction: Monitoring of health behaviours, especially of adolescents, is essential for the future of each nation. Over the last decades, many changes have occurred in all aspects of our lives, affecting the health and quality of life of all people, including children and adolescents. Methods: The study is based on a quantitative research method. The survey was conducted on a representative sample of Slovenian 11-, 13- and 15-year-old adolescents, using a standardised international questionnaire (HBSC study - Health Behaviour in School-Aged Children). The survey was carried out with the assistance of school counsellors in the spring of 2002, 2006 and 2010 (n = 15.080). For determining the correlation between two individual years, the chi-square test was used. The significance level was calculated using the statistical significance value of p < 0.05. Through the Cochran-Armitage trend test, it was established whether a trend existed for the selected indicators in the period between 2002 and 2010. Results: There are some favourable trends, e.g. eating breakfast (p = 0.000), tooth brushing (p = 0.000), lower proportion of individuals who rate their health as poor (p = 0.002) and experience several psychosomatic symptoms (p = 0.000), but also unfavourable trends, e.g. decrease in physical activity (p = 0.023), increase in early alcohol consumption (p = 0.000), dissatisfaction with school (p = 0.000) and bullying others (p = 0.000). Discussion and conclusion: The conclusions of the analyses can serve as a useful basis for further work and development of systemic measures to promote healthy behaviours and prevent risky and unhealthy behaviours among children and adolescents.

7. Enhanced oral glucose tolerance test for early detection of insulin resistance and metabolic complications in children with obesityUrh Grošelj, Jan Kafol, Jaka Šikonja, Matej Mlinarič, Robert Šket, Žiga Iztok Remec, Jernej Kovač, Ana Drole Torkar, Jasna Šuput Omladič, Barbka Repič-Lampret, Tadej Battelino, Primož Kotnik, 2025, izvirni znanstveni članek Povzetek: Background and aims: Early detection of insulin resistance (IR) and obesity-related complications is crucial for preventing type 2 diabetes. This study aimed to identify dynamic metabolic biomarkers for more precise early detection of IR and metabolic abnormalities. Methods: This cross-sectional cohort study evaluated IR and metabolic biomarkers in 403 children with obesity (median age 13.18 years, 51.3 % female, 98.5 % with obesity) using an enhanced oral glucose tolerance test (eOGTT). IR was assessed via four indices, with the Matsuda Insulin Sensitivity Index (ISI-M) used as the primary measure. Participants were stratified into quartiles based on ISI-M. Results: Participants with the highest IR (Q1) were older (p = 0.002), had a higher body mass index, were in a more advanced pubertal stage (p < 0.001), and had significantly elevated glucose and insulin levels (p < 0.001 for both) compared to the most insulin sensitive (Q4), with significant differences observed across all quartiles (p < 0.050 for all). Insulin at 120 min demonstrated excellent diagnostic accuracy for IR (AUC=0.958). Triglyceride levels in Q1 showed minimal decline during the eOGTT, while greater declines were observed with increasing insulin sensitivity (p = 0.002 across quartiles), suggesting that a lack of decline in triglycerides may help identify IR. High-sensitivity C-reactive protein levels increased with IR (p = 0.024). Baseline beta-hydroxybutyrate levels were highest in the Q4 and showed the greatest absolute decrease during the eOGTT, compared to Q1 (p < 0.001 for both). Conclusions: We validated established IR markers in children with obesity, while demonstrating that eOGTT may offer improved characterization and earlier identification of those at risk for metabolic complications.

8. Dietary intake of adolescents and alignment with recommendations for healthy and sustainable diets : results of the SI.Menu studyRok Poličnik, Hristo Hristov, Živa Lavriša, Jerneja Farkaš-Lainščak, Sonja Smole Možina, Barbara Koroušić-Seljak, Urška Blaznik, Matej Gregorič, Igor Pravst, 2024, izvirni znanstveni članek Povzetek: Background: The SI.Menu study offers the latest data on the dietary intake of Slovenian adolescents aged 10 to 17. The purpose of this study is to comprehensively assess their dietary intake (energy and nutrients) and compare their food intakes with dietary recommendations for healthy and sustainable diets. Methods: The cross-sectional epidemiological dietary study SI.Menu (March 2017–April 2018) was conducted on a representative sample of Slovenian adolescents aged 10 to 17 years (n = 468) (230 males and 238 females). Data on dietary intake were gathered through two nonconsecutive 24 h recalls, in line with the European Food Safety Authority (EFSA) EU Menu methodology. The repeated 24 h Dietary Recall (HDR) and Food Propensity Questionnaire (FPQ) data were combined to determine the usual intakes of nutrients and food groups, using the Multiple Source Method (MSM) program. Results: Adolescents’ diets significantly deviate from dietary recommendations, lacking vegetables, milk and dairy products, nuts and seeds, legumes, and water, while containing excessive meat (especially red meat) and high-sugar foods. This results in insufficient intake of dietary fibre, and nutrients such as vitamin D, folate, and calcium. Conclusions: The dietary intake of Slovenian adolescents does not meet healthy and sustainable diet recommendations. This study provides an important insight into the dietary habits of Slovenian adolescents that could be useful for future public health strategies.

9. School belongingness and family support as predictors of school bullying perpetration and victimization in adolescents : are relations the same for students with an immigrant background?Katja Košir, Martina Zakšek, Ana Kozina, 2023, izvirni znanstveni članek Povzetek: The aim of the study was to examine school belongingness and family support as predictors of bullying behavior and victimization, and the moderating role of students’ gender and immigrant background in a large representative sample of Slovenian adolescents (N = 1925; 42.50% male). The results indicated that school belongingness significantly predicted both bullying and victimization. Family support did not contribute to the incremental validity beyond school belongingness in predicting victimization. Gender was found to moderate the relationship between school belongingness and both bullying outcomes. The relationship between school belongingness and victimization was stronger for students with an immigrant background.
