Internet is important resource of health-related information and health services. Factors associated with higher level of online health (eHealth) literacy among adolescence have been understudied. The aim of this study was to assess psychometric properties of the eHealth Literacy Scale (eHEALS) in Serbian language and to evaluate eHealth literacy among adolescents in Serbia. The study was carried out in four high schools in Belgrade, Serbia in the period December 2016 to January 2017. A total of 702 students comprised the study sample. The eHEALS was translated according to internationally accepted methodology and its psychometric properties were analyzed. The Cronbach's alpha coefficient for the entire eHEALS was 0.849. On exploratory factor analysis we obtained two-factorial structure. Our adolescents reported low confidence in knowing what health resources are available online. High confidence was observed for knowing how to use and how to find health information online. There was no difference in eHEALS score between genders or between school years. After adjustment for gender, type of school program, parental marital status, fathers' education level and household income, being female was associated with higher eHealth literacy (B = 1.12, 95% confidence interval 0.07-2.18; p = 0.036). Serbian version of the eHEALS is a valid instrument in assessment of online health literacy and can be further used in evaluation of eHealth literacy in other population groups in Serbian language. It is advised that some classes in school are dedicated to appraisal and use of online health websites. This could be achieved through peer-education. © 2018 The Author(s).

Background: Many adolescents believe that online health information is reliable, particularly when they are familiar with the source of information. Objective: To analyse the degree of influence of online health information on high school students' health decisions and examine whether socio-demographic characteristics, digital literacy, use of different websites and interest in specific health topics are associated with a stronger influence of online health information on adolescents' health-related decisions. Methods: Participants were students from four public high schools in Belgrade, Serbia. Socio-demographic and behavioural questionnaire as well as the e-health literacy scale (eHEALS) were used to collect data. Results: The study sample comprised 702 students. A total of 79.6% of students reported that online health information influenced their health decisions to a certain extent (from ‘a little’ to ‘a lot’). Being a boy, using the internet since younger age, better self-perceived e-health literacy, using health apps, Google, health forums, websites of health institutions, social media and YouTube, being interested in diet/nutrition, sexually transmitted infections and cigarettes were the characteristics associated with a stronger influence of online health information on students' health decisions. Conclusion: This study provides clues about how online health-related information can be used to adjust and enhance health promotion amongst adolescents. © 2022 Health Libraries Group.

Objective: Tracking of periods is recommended to adolescent girls because of their irregular menstrual cycle and longer cycle length compared to adult women. The purpose of this study was to examine the prevalence of use of apps to track menstrual cycle among high school girls from Belgrade, Serbia, as well as to define factors associated with their use. Methods: A study was carried out in December 2016 and January 2017. The study included 394 high school girls from Belgrade, Serbia, who used smartphones. The students were asked to fill in an anonymous questionnaire about socio-demographic characteristics, use of online platforms and smartphone apps as well as online health (e-health) literacy scale (eHEALS). Results: The prevalence of tracking menstrual cycle via smartphone apps was 29.7%. The multivariate logistic regression model showed that studying humanities-languages school program, using Wikipedia, websites run by physicians, health forums, but not YouTube were associated with use of menstrual cycle tracking apps. Girls who used fitness apps were more likely to use apps to track menstrual cycle. Conclusion: Approximately one third of girls in Belgrade highs schools who have smartphones used menstrual cycle tracking apps. Use of different digital media might influence the decision to track menstrual cycle via smartphone apps. © 2020 by the University Clinical Centre Tuzla, Tuzla, Bosnia and Herzegovina.

Background: Browsing webpages that offer health information allows visitors to remain anonymous, particularly when researching sensitive topics. Uncertainty about confidentiality may be a barrier for adolescents to discuss their health in-person with a physician and seek further health information on the Internet after seeing a physician. Objective: To explore factors contributing to perceived online health information seeking after visiting a physician in a sample of high school students. Methods: A cross-sectional study was conducted from December 2016 to January 2017. The study included 702 high school students. Socio-demographic and behavioral questionnaire as well as the electronic health (e-health) literacy scale (eHEALS) were used to collect data. Students described their perceptions of what they commonly do after visiting a physician, which was not connected to a particular clinic at any point in time. Results: A total of 347 students (49.4%) perceived that they search for online health information after visiting a physician. Attending humanities-languages school program, lower education level of parents, being older at first Internet use, stronger influence of online health information on students' behaviour, better e-health literacy, use of smartphones, YouTube, social networks and heath forums were associated with perceived online health information seeking after visiting a physician. Conclusion: One-half of high school students in this study perceived that they search for online health information after having visited a physician. Our results suggest that many adolescents might seek additional information about health. © 2021 Oxford University Press. All rights reserved.

Objectives: Fear of being judged and stigmatized has been reported as barriers for adolescents to timely use healthcare services. The objective of this study was to examine the prevalence and factors associated with online health information seeking instead of seeing a physician among high school students. Methods: A cross-sectional questionnaire-based study was carried out in four out of 21 public high schools in Belgrade, from December 2016 to January 2017 (n = 702, 41.9% males, 15–19 years old). The association of socio-demographic characteristics, digital literacy, interest in health topics and the use of online platforms with health information seeking was analysed using multinomial regression models. Results: More than half of high school students (56.6%) search for online health information instead of seeking a physician. Being male, having lower-grade point average, attending humanities-languages program, older age at first Internet use, better e-health literacy, use of smartphones, interest in sexually transmitted diseases and mental health, use of websites run by physicians and Youtube was associated with online health information seeking instead of in-person visit to a physician. Conclusions: Setting up safe and supportive online platform could help adolescents improve health education. Physicians who see adolescent patients should encourage discussions about sensitive health topics. © 2020, Swiss School of Public Health (SSPH+).

Background: Numerous health apps focusing on fitness, nutrition, and physical activity are available, yet many adolescents have never used them. The purpose of this study was to assess the prevalence of the use of fitness and diet apps and related socio-demographic factors and digital behaviors among high school students. Study Design: A cross-sectional study. Methods: High school students were recruited from 4 out of 21 public high schools in Belgrade, Serbia. Participants filled out an anonymous questionnaire about socio-demographic characteristics and digital behaviors, along with the e-health literacy scale (eHEALS). Adjusted logistic regression was applied for data analysis using SPSS 20. Results: Of the 702 students who completed the questionnaire, 670 used smartphones (95.4%; average age 16.5 ± 1.2 years). The prevalence of fitness and diet app use among girls was 29.7% and 9.6%, as well as 17.3% and 3.6% among boys, respectively. Having higher family income, having better e-health literacy, browsing websites about fitness and diet, and using diet apps but not watching YouTube were associated with the use of fitness apps among girls. Being younger and browsing fitness websites and YouTube were associated with the use of fitness apps among boys. Being younger, browsing websites about diet, and using fitness apps were associated with the use of diet apps among girls. Conclusion: Based on the findings, girls used fitness and diet apps more often than boys. Practical demonstrations on how to utilize certain health apps could be an additional opportunity to support positive health behaviors among adolescents. © 2024 The Author(s).
