Resumo: | Purpose: To describe levels of physical activity in adolescents (10-19 years) living in Southern Brazil, and to explore the association between sedentary lifestyle and demographic, economic, health-related, and parental variables. Methods: Population-based cross-sectional study including 857 adolescents selected through a multistage random sampling strategy. Sedentary lifestyle was defined as <300 min/wk of moderate to vigorous physical activity, following current recommendations for adolescents. Physical activity data collected by questionnaire were compared with pedometer counts and with a longer version of the questionnaire in a sub-sample of 92 adolescents. A cutoff point of 10,000 steps per day was used for classifying adolescents as sedentary or not by pedometers. Results: Reliability of the questionnaire was good, and its validity in comparison to a longer questionnaire was also satisfactory. Although the sensitivity of the questionnaire for detecting sedentary lifestyle in comparison to pedometers was good (77.1%), its specificity was low (42.6%). The prevalence of sedentary lifestyle by questionnaire in the whole sample was 69.8% (CI95% 66.7; 72.9). Boys were more active than girls. The prevalence of sedentary lifestyle increased with age in girls, but not in boys. Among boys, those from low economic levels were more likely to be sedentary. Among girls, paternal physical activity was directly associated with adolescent activity levels. Conclusion: Urgent strategies aimed at increasing levels of activity of adolescents are necessary in Brazil given the high prevalence of sedentary lifestyle detected in this study. The variables associated with sedentary lifestyle in adolescence varied between boys and girls. |

Os resultados revelam que 70% dos adolescentes não praticam uma quantidade de atividade física suficiente para obtenção de benefícios à saúde. Entre os meninos esta proporção é de 57% e entre as meninas é ainda maior (82%). Segundo recomendações atuais, todo adolescente deve praticar pelo menos 60 minutos por dia de atividade física na maioria dos dias da semana. O autor aponta que os resultados da investigação são preocupantes, visto que a prática regular de atividades físicas na adolescência traz benefícios à saúde na própria adolescência e até na vida adulta. Dentre os entrevistados 19% dos meninos e 33% das meninas não haviam praticado sequer uma atividade física com duração de pelo menos 10 minutos seguidos na semana anterior à entrevista. Entre as meninas, foi observado um declínio no nível de atividade física durante a adolescência. A obesidade tem aumentado substancialmente nessa idade e o sedentarismo é um dos principais responsáveis por essa elevação. Os autores reforçam a necessidade de estratégias efetivas de combate ao sedentarismo na adolescência, principalmente com um estímulo à prática de atividades físicas prazerosas e que tenham um significado cultural na vida dos 81 adolescentes. Intervenções que atuem nas aulas regulares de Educação Física também devem ser priorizadas.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em EpidemiologiaUFPelBRMedicinaEstilo de vida sedentárioAtividade físicaAdolescentesEpidemiologiaBrasilSedentary lifestyleExerciseAdolescentsCNPQ::CIENCIAS DA SAUDE::SAUDE COLETIVA::EPIDEMIOLOGIAPrevalência de sedentarismo e fatores associados em adolescentes.Prevalence of sedentary lifestyle and associated factors in brazilian adolescents.info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesishttp://lattes.cnpq.br/1037419643767453http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4792761E6Hallal, Pedro Rodrigues Curihttp://lattes.cnpq.br/3211152266266081Araújo, Cora Luiza PavinBastos, Juliano Peixotoinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALJuliano_Peixoto_Bastos_dissertacao.pdfapplication/pdf580130http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1975/1/Juliano_Peixoto_Bastos_dissertacao.pdfce478477d6f0acc733a01bb587de767bMD51open accessTEXTJuliano_Peixoto_Bastos_dissertacao.pdf.txtJuliano_Peixoto_Bastos_dissertacao.pdf.txtExtracted Texttext/plain100121http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1975/2/Juliano_Peixoto_Bastos_dissertacao.pdf.txtc30ef894835c51f7e0a352a19fb6bed1MD52open accessTHUMBNAILJuliano_Peixoto_Bastos_dissertacao.pdf.jpgJuliano_Peixoto_Bastos_dissertacao.pdf.jpgGenerated Thumbnailimage/jpeg1463http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1975/3/Juliano_Peixoto_Bastos_dissertacao.pdf.jpg78e92cc91fd3b8428da35386bcb51dc9MD53open access123456789/19752024-04-20 09:14:16.404open accessoai:guaiaca.ufpel.edu.br:123456789/1975Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2024-04-20T12:14:16Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
