Resumo: | Physical inactivity is considered an independent risk factor for chronic diseases, and time spent in front of the TV is one of the most widespread sedentary activities. The purpose of this study was to investigate the association between time spent in front of the TV and energy expenditure among adolescents with different percents of body fat (%BF). The study included 40 White male adolescents aged 14 to 16 years, of high socioeconomic status (classes A and B). Anthropometric (body mass, stature, skin folds) and level of physical activity (Tritac accelerometer TR3) data were obtained. The adolescents were divided by %BF: below of 11% or above of 20%.The results demonstrated that adolescents with %BF above the ideal range spent more time in front of the TV and had lower energy expenditure than adolescents with %BF below the ideal range (p < 0.05). A negative association was observed between time in front of the TV and energy expenditure (on weekdays: r = - 0.426; on weekends: r = - 0.579) and there was a positive correlation with body fat (on weekdays: r = 0.518; on weekends: r = 0.514) (p < 0.05). According to the evidence, it was concluded that the greater the amount of time spent in front of the TV, the greater the prevalence of inactivity and the greater the amount of body fat. |

O propósito do presente estudo foi verifi car a associação entre o tempo em frente à TV e o gasto calórico em adolescentes com diferentes percentuais de gordura corporal (%G). Participaram do estudo 40 adolescentes de 14 a 16 anos, do sexo masculino, com nível socioeconômico elevado (A e B) e da cor branca. Foram coletados dados antropométricos (massa corporal, estatura, dobras cutâneas) e nível de atividade física (acelerômetro Tritac). Os adolescentes foram divididos de acordo com o %G: abaixo do ideal (< 11%) e acima do ideal (> 20%). Os resultados demonstraram que os adolescentes com %G acima do ideal apresentaram maior tempo gasto em frente à TV e menor gasto calórico em relação aos adolescentes com %G abaixo do ideal (p < 0,05). Foi verificada associação negativa entre o tempo em frente à TV e o gasto calórico (dia de semana: r = - 0,426; fi nal de semana: r = - 0,579) e correlação positiva com a gordura corporal (dia de semana: r = 0,518; fi nal de semana: r = 0,514) (p < 0,05). De acordo com as evidências encontradas, conclui-se que quanto maior o tempo gasto em frente à TV, maior a prevalência de sedentarismo e maior a quantidade de gordura corporal.Universidade Federal de Santa Catarina.
