Background/Objectives: Human papillomavirus (HPV) is a causative agent of infections and cancers of the reproductive and digestive tract, and vaccination is the most effective prevention method. This research aimed to assess the impact of health education on vaccination coverage and knowledge of the school population related to HPV infection and vaccination. Methods: This non-randomized clinical trial included 170 participants out of the 221 students in the generation of 2022/2023, who were divided into a group of Subjects and Controls and who self-assessed their knowledge and tested knowledge at four and two time points, respectively. Results: The study examined whether there is a difference in the share of vaccinated students of the entire generation compared to the previous generation (62% vs. 47%). The self-assessment and assessment of one’s knowledge in the group of subjects was significantly lower before education than during other time points during the research. At “moment zero”, there was no significant difference in the knowledge assessment between the groups. However, after 8 weeks, the knowledge assessment was significantly higher in the Subject group. Conclusions: The results suggest a positive impact of health education, which may contribute to raising awareness about the importance of prevention and vaccination against HPV.

The prevalence of adolescent idiopathic scoliosis (AIS) is increasing, partly due to a lack of physical activity. In a cross-sectional study with 18,216 pupils (5th, 6th, and 8th grades) from four Croatian counties using the forward bend test (FBT; presumed AIS), the prevalence of AIS and its correlation with physical activity were evaluated. Pupils with presumed AIS were less physically active than their peers without scoliosis (p < 0.001). Abnormal FBT was more prevalent among girls than boys (8.3% vs. 3.2%). Boys were more physically active than girls (p < 0.001). Pupils with presumed AIS were less physically active than their peers without scoliosis (p < 0.001). A higher prevalence of presumed AIS was found among inactive or just recreationally active schoolchildren than among those engaged in organized sports (p = 0.001), girls especially. Pupils with presumed AIS were less active and had fewer weekly sports sessions than their peers without scoliosis (p < 0.001). Notably low prevalence of AIS was detected among pupils engaged in soccer (2.8%, p < 0.001), handball (3.4%, p = 0.002), and martial arts (3.9%, p = 0.006), while it was higher than expected in swimming (8.6%, p = 0.012), dancing (7.7%, p = 0.024), and volleyball (8.2%, p = 0.001) participants. No difference was detected for other sports. A positive correlation was found between time spent using handheld electronic devices and the prevalence of scoliosis (r_s = 0.06, p < 0.01). This study confirms the increasing prevalence of AIS, particularly among less athletic girls. Further, prospective studies in this field are required to explain whether the higher prevalence of AIS in these sports is due to referral or other aspects.

Specific personality traits may predispose individuals to various forms of addictive behaviors. This study aimed to investigate the association between personality traits of university students and Internet addiction (IA). A sample of 1051 university students was recruited from the largest university in Eastern Croatia. A structured anonymous questionnaire that included questions regarding students’ sociodemographic information and Internet usage patterns, the Young Internet Addiction Test and Big Five Inventory served as a research tool. The study revealed that 1.0% of the studied sample expressed severe IA while 24.6% of study participants expressed some signs of addiction. The IA was detected in 576 (80.0%) students who used the Internet mainly for social networking, in 30 (78.9%) students who mainly used it for online gaming, and in 153 (52.2%) students who mainly used it for university assignments (p < 0.001). Higher neuroticism, higher extraversion, and higher openness to new experiences were connected with IA in general (p < 0.001). Higher neuroticism, higher extraversion, and higher openness to new experiences were significantly associated with addictive behavior during social networking (p < 0.001). Higher extraversion and higher openness to new experiences were significantly associated with addictive behavior during Internet usage for university assignments (p = 0.025), while there were no significant associations between specific personality traits and addictive behavior during online gaming (p = 0.059). Personality traits must be taken into account while developing programs and implementing interventions for preventing IA in the university student population.

Introduction: The study aimed to examine the prevalence of sports outside of regular school classes among primary and secondary school students. The secondary aim was to study the correlation of physical activity, students’ socioeconomic status and parents’ level of education with students’ educational outcomes.Material and Methods: Data were collected from medical records of the Croatian Institute for Health Insurance in the Osijek-Baranja County and through regular physical examination of students in the fifth and eighth grade of primary school and the first grade of secondary school.Results: Over a 5-year period, 120 boys and 141 girls were examined; 66.28% of the students were involved in sports activities in the fifth grade, 49.04% were involved in sports in the eighth grade, and in the first grade, 43.68% of students were involved in sports. No statistically significant differences were observed in the seventh and eighth grade of primary school (p = 0.076) and in the first grade of secondary school (p = 0.057). Students in the seventh and eighth grade who played sports had slightly higher grades (4.45 ± 0.68) compared to those who did not participate in sports activities (4.3 ± 0.69). Similar results were obtained for students who were involved in sports in the first grade of secondary school, who had achieved slightly better results in the seventh grade (4.41 ± 0.69) compared to those who did not participate in sports activities (4.41 ± 0,69).Conclusion: The results of this study suggest that physical activity in children could be associated with better school performance, which may have implications for sports having positive health benefits in both childhood and adulthood.

Nutrition care delivered in primary health care setting is an effective and necessary preventive health care measure. General practitioners (GPs) nutrition knowledge is related to their nutrition care practice. The aim of this study was to explore the nutrition knowledge of Croatian GPs, and to investigate its connection with the implementation of nutrition care in GPs’ offices. A cross-sectional study was conducted among 17.0% of randomly selected GPs, from May to July 2013, via an anonymous questionnaire. The study showed that only 35.8% of the Croatian GPs had an adequate level of nutrition knowledge (five or more correct answers to nutrition questions). The study further revealed that females, GPs with additional education in nutrition and GPs who had not suffered from chronic diseases with poor nutrition posing as a risk factor had better nutrition knowledge (p = 0.029, p < 0.001 and p = 0.041, respectively). The Spearman rank correlation between GPs’ nutrition knowledge and the implementation of nutrition care in their offices during daily work with patients was r_s = −0.190 (p < 0.001). To provide nutrition care in GPs’ offices in Croatia, strategies for improving GPs’ nutrition knowledge are needed.
