Prática de atividade física e fatores associados em adolescentes no Nordeste do Brasil

Abstract

OBJECTIVE:To estimate the proportion of physically active adolescents and identify associated factors. METHODS:The sample was composed of 2,874 high school students (public and private schools) aged 14 to 19 years in the city of João Pessoa, Northeastern Brazil. Physical activity level was measured by means of a questionnaire and considered physically active if ≥ 300 minutes/week. Sociodemographic variables were analyzed, as well as nutritional status, sedentary behavior, self-report of health status and participation in physical education classes. The prevalence ratio was used as association measure, estimated by means of Poisson regression. RESULTS:The prevalence of physical activity was 50.2% (95%CI: 47.3;53.1). Male adolescents were more physically active than female adolescents (66.3% vs. 38.5%; p<0.001). The factors directly associated with practice of physical activity were: father's higher level of schooling for the male sex and mother's higher level of schooling for the female sex, positive self-reported health status, and participation in physical education classes. CONCLUSIONS:The majority of the adolescents was classifi ed as physically active, particularly the male youths. Adolescents with parents whose level of schooling was higher, with positive health status perception, and who participated in physical education classes were more likely to be physically active.

“…12 In this context, exercise for young people becomes a public health priority, 3 and suggests the need to implement programs aimed at school age children and adolescents. 12 This study showed that male adolescents, in both the intervention and control group, are more physically active than their female counterparts, which concurs with the literature which, in turn, indicates that this difference between sexes is due to socio-cultural, historic and biological elements.…”

“…12 This study showed that male adolescents, in both the intervention and control group, are more physically active than their female counterparts, which concurs with the literature which, in turn, indicates that this difference between sexes is due to socio-cultural, historic and biological elements. 3,12 Studies recommend establishing exercise programs for adolescents, especially for girls, as they are at higher risk of being physically inactive. The proposals emphasize that the activities should be interesting, and mean something to the pupils and live up to their expectations.…”

Estágios de mudança de comportamento para atividade física em adolescentes: revisão sistemática

“…Contudo, a Europa e os Estados Unidos possuem mais que o dobro (13,03%, IC95% 12,26;13,83 e 12,78%, IC95% 11,53;14,11, respectivamente) da prevalência encontrada na América do Sul (6,72%, IC95% 6,25;7,22 …”

“…No que diz respeito aos estudos envolvendo adolescentes e AF, não foi encontrada revisão de literatura sobre a temática abordada no presente estudo. Grande parte da literatura aponta prevalências 7,8 e fatores associados [9][10][11] analisando apenas comportamentos ativos e/ou inativos de prática de AF. Ainda, dentre os estudos que investigaram os EMC para AF em adolescentes, é possível perceber que muitos autores agrupam as categorias de EMC, não permitindo a análise do perfil de cada estágio de maneira separada, o que vai de encontro à proposta inicial do Modelo Transteórico, podendo acarretar em adolescentes com diferentes intenções para AF agrupados em uma mesma categoria.…”

Prática esportiva e participação nas aulas de educação física: fatores associados em estudantes de Londrina, Paraná, Brasil

“…Do ponto de vista epidemiológico, grande atenção tem sido dada em investigar a prevalên-cia e os fatores associados à prática de atividade física em crianças e adolescentes brasileiros 16,17,18,19 . No entanto, há carência de informações acerca dos fatores associados à prática esportiva e participação nas aulas de educação física nessa faixa etária, o que impede a elaboração de programas de intervenção que poderiam contribuir para a diminuição da alta prevalência de jovens inativos 17 .…”
