ABSTRACT
ABSTRACT

Objective:

To identify the impact of physical activity correlates with the isolated and combined presence of insufficient physical activity and high screen time among adolescents.

Methods:

A cross-sectional representative study was carried out with a sample of 786 adolescents (16.0±1.0 years; 53.9% girls) randomly selected in the schools of São José dos Pinhais, Paraná, Southern Brazil. The physical activity correlates analyzed were sex, nutritional status, economic class and sexual maturation. Physical activity level and screen time were measured and classified according to reference criteria. The associations were tested with Poisson regression and the population attributable fraction (PAF) verified the impact of correlates on the combined presence of insufficient level of physical activity and high screen time by the prevalence ratio (PR).

Results:

Among the studied adolescents, 84.7% (n=666) were considered insufficiently active, 96.4% (n=758) reported high screen time and 82.1% (n=645) presented the combined presence of these behaviors. The female sex and the high economic status were positively associated with the insufficient level of physical activity (PR=1.19; 95% confidence interval - 95%CI 1.12-1.27; PAF=15.97 - female/adjusted; PR=1,1; 95%CI 1,01-1,19; PAF=9,09 - high/adjusted class). The female sex also was positively associated to high screen time after adjustments (PR=1.18; 95%CI 1.10-1.27; PAF=15.25). The female sex was positively associated with the combined presence of these behaviors (PR=1.18; 95%CI 1.10-1.27) with a 15.25% impact on these behaviors.

Conclusions:

Physical activity correlates can have an impact on the insufficient level of physical activity and high screen time, especially among girls.
RESUMO
RESUMO

Objetivo:

Identificar o impacto dos correlatos da atividade física (AF) com a presença isolada e a combinada da prática insuficiente de AFs e do elevado tempo de tela em adolescentes.

Métodos:

Estudo transversal, representativo, com amostra de 786 adolescentes (16,2±1,1 anos; 53,9% de meninas) selecionados aleatoriamente nas escolas de São José dos Pinhais, PR. Foram analisados sexo, estado nutricional, classe econômica e maturação sexual. Foram mensurados o nível de AF e o tempo de tela. As associações foram testadas com a regressão de Poisson e a fração atribuível populacional (FAP) verificou o impacto dos correlatos na presença combinada do nível insuficiente de AF e do elevado tempo de tela pela razão de prevalência (RP).

Resultados:

Foram considerados insuficientemente ativos 84,7% (n=666), com elevado tempo de tela, 96,4% (n=758), e 82,1% (n=645) dos adolescentes apresentaram a presença combinada desses comportamentos. O sexo feminino e a classificação econômica elevada estiveram positivamente associados aos níveis insuficientes de AF (RP=1,19; intervalo de confiança de 95% [IC95%] 1,12-1,27; FAP=15,97 - feminino/ajustado; RP=1,1; IC95% 1,01-1,19; FAP=9,09 - classe elevada/ajustado). O primeiro também se apresentou positivamente associado ao elevado tempo de tela após os ajustes (RP=1,18; IC95% 1,10-1,27; FAP=15,25) e mostrou-se associado positivamente à presença combinada desses comportamentos (RP=1,18; IC95% 1,10-1,27), com um impacto de 15,25% sobre essas condutas.

Conclusões:

Correlatos da AF podem ter impacto sobre o nível insuficiente de AFs e elevado tempo de tela, quando investigados de formas isolada e combinada, principalmente em relação às meninas.
