AbstractsObjective: Little is known about the prevalence of nutritional supplement use in European adolescents. We conducted the present study to analyse the prevalence of nutritional supplement use and factors associated with this use among Slovenian adolescents. Design: The nutritional supplementation practices of 818 adolescents were studied using an anonymous questionnaire. Information was sought on the type of supplements used, frequency of use and sources of information. Setting: The region of north-west Slovenia. Subjects: Schoolchildren from twenty primary schools and twelve secondary schools. Results: Some 19?3% of all adolescents reported using at least one nutritional supplement and the prevalence of use was significantly higher in adolescents who were members of sports clubs. Multivitamins were the most common nutritional supplement. Older adolescents were significantly more likely to be supplementing with iron, protein and minerals. Less than 16 % of supplement users in our study sought information from health-care professionals. Nearly 62 % obtained information from parents and coaches, and many adolescents appear to decide on nutritional supplementation themselves, without advice. Older adolescents were significantly more likely to combine supplements than younger adolescents. Conclusions: One-fifth of Slovenian adolescents use nutritional supplements. There are clear differences in supplement use between younger (age 12 years) and older (age 17 years) adolescents. Multiple use of supplements, coupled with self-managed supplementation in older adolescents, is concerning. Hence, there is an urgent need to provide accurate information regarding nutritional supplements, which will help adolescents, their parents and coaches to make informed choices about their use.
To evaluate the pro-environmental behaviour of visitors in the Alps, we surveyed 100 hikers on two hiking trails in Triglav National Park (NP) in Slovenia during the 2010 and 2012 summer seasons. We collected demographic data on hikers and examined 1) pro-environmental behaviour at home, 2) willingness to pay for environmentally friendly goods and services, and 3) enrolment in environmental education and involvement in conservation projects. We identified 13 significant correlations between pro-environmental behaviour questions and demographically based hikers' groups. Level of education and enrolment in environmental educational activities predicted pro-environmental behaviour and attitudes toward conservation. Our results show that visitors who hike in Triglav NP come in pairs or with friends, value nature, and are prepared to pay more for goods with eco-labels and services from environmentally responsible suppliers. Only 36,7% have enrolled in an educational programme, training, workshop or activity. The majority of respondents choose the location for their vacation based on an area's nature preservation characteristics. We discuss the factors that influence hikers' pro-environmental behaviour and investigate the relationship between level of education and hikers' pro-environmental behaviour at home. We also examine the importance of nature preservation characteristics in hikers' choice of vacation destination. Finally, this research provides valuable data for understanding hikers' behaviour and suggestions for managers of protected areas to create tourism offers that are more educational and environmentally friendly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
