Adolescents in the industrial world are becoming less physically active and are increasingly adopting a sedentary life-style in front of computers and television screens.
to determine self-related health, physical activity, sleeping habits, prevalence of overweight, and body complaints in Australian senior high school students.
Participants were 466 high school students aged 15-17 years enrolled in academic and vocational programs. A questionnaire was completed at two senior high schools with questions about weight and height, health, physical activity, type of physical activity/sport, intensity, sleeping habits, and possible injuries or complaints during the last three months.
Seventy seven percent of the high school students participated in sports on a regular basis. Compared with vocational programs, more males and females in academic programs participated in sports (71% and 80% respectively) (p = .036). Males reported significantly better health than females (p < .0001). 65% of the study group reported body complaints during the last 3 months. A higher number of females than males reported complaints about the back (p = .007) and the hip (p = .05). Good sleep was reported in 82.1% of males and in 76.6% of females. In males, 44.3% were often sleepy in the daytime (females 56.6%, p < .01).
Underweight, physical activity and good sleep are factors with significant positive effect on good health, whereas overweight is a negative factor. Proper sleep habits and higher physical activity levels should be promoted among high school students, and TV viewing time and video game use restricted. Additionally, schools should provide opportunities for young people to participate in a wider range of physical activities that address their individual needs while promoting the health benefits of engaging in regular exercise.
[Show abstract][Hide abstract] ABSTRACT: O objetivo do presente estudo foi sintetizar por meio de revisão sistemática as evidências disponíveis quanto à associação entre a prática de atividades físicas e a percepção de saúde em adolescentes. As buscas foram realizadas em bases de dados eletrônicas (SCOPUS, PUBMED/MEDLINE, LILACS e SCIELO) e na lista de referências dos artigos identificados.Foram incluídos artigos originais publicados até 2009, em qualquer idioma. A busca dos artigos foi baseada nos descritores sugeridos pelo MeSH e em termos específicos que vêm sendo utilizados para designar as variáveis “percepção de saúde” e “atividade física”. Foram analisados 16 estudos, nenhum estudo envolvendo adolescentes brasileiros. A maioria dos estudos foi transversal quanto ao delineamento, publicado nos últimos cinco anos (2005-2009), utilizou medidas subjetivas de atividade física (questionários e diários de atividade)e operacionalizou a medida da percepção de saúde por uma única pergunta. Em 14 dos 16 estudos analisados, verificou-se uma associação direta entre a prática de atividade física e uma percepção de saúde mais positiva. Concluiu-se que a prática de atividade física está associada à percepção de saúde neste grupo populacional; todavia, devido ao delineamento transversal dos estudos realizados não se pode estabelecer uma relação causal entre estes fatores.
[Show abstract][Hide abstract] ABSTRACT: Stemming from the social media (Web 2.0) phenomenon, this paper will discuss how such modern communication technologies have inadvertently caused a paradigm shift throughout the Australian school health education landscape. Furthermore, attention will be directed towards investigating the ensuing challenges, potentials and transformations occurring in the learner engagement and interaction processes these technologies have collectively promoted. In particular, this paper will present the wider repercussions such modern forms of communication will have on future issues relating to the national curriculum, pedagogy and epistemology. Moreover, deliberation will be directed towards presenting contemporary case studies which illustrate how early twenty-first century technologies are being implemented to heighten health information retrieval and support collaborative learning environments. This paper identifies that Web 2.0 adoption and absorption into the educational ecosystem is still very much in its infancy and will require a rigorous effort by educationalists if its full potential is to be realised and harnessed for future twenty-first century school health education settings.
