Screen time and nutritional status of schoolchildren from the city of Suzano-SP/TEMPO DE TELA E ESTADO NUTRICIONAL DE ESCOLARES DA CIDADE DE SUZANO-SP

In addition to hypercaloric diets the overuse of technology has contributed to overweight in childhood. This is because, normally, its users remain for a long time sitting or lying down during their use, contributing to a reduction in energy expenditure and, consequently, to an increase in body fatness. The objective of this study was to verify the screen time associated with the nutritional status of students enrolled in the 1st year of primary education in the city of Suzano-SP. The anthropometric variables were stature (cm), body weight (kg), body mass index (BMI, kg / m2) and screen time (h). Statistical analysis was performed with Biostat 5.3 software. The results were presented on average, standard deviation, absolute frequency and simple relative, being considered a level of significance of 5% (p [less than or equal to] 0.05). In girls there was a higher prevalence of overweight (39.53%), while obesity was higher in boys (14.1%). On the screen time 26.92% of boys exceeded the daily recommendation of 2 hours, while in girls this figure was 11.62 %. There was no correlation between BMI and boys' screen time (r = 0.0226), but for girls it was possible to observe a weak correlation between these variables (r = 0.3753). Finally, there was a higher prevalence of overweight in females and obesity in males. A representative part of the schoolchildren, especially the boys, use more than two hours daily of screen. We observed a weak correlation between screen time and BMI for females. Key words: Body Mass Index. Screen Time. School children. Alem de dietas hipercaloricas a utilizacao excessiva de tecnologia tem contribuido para o excesso de peso na infancia. Isto porque, normalmente, seus usuarios permanecem muito tempo sentados ou deitados, durante sua utilizacao, contribuindo para uma reducao do gasto energetico e, consequentemente, para o aumento da adiposidade corporal. O objetivo deste estudo foi verificar o tempo de tela associado ao estado nutricional de escolares matriculados no 1 ano do ensino fundamental da cidade de Suzano-SP. Foram verificadas as variaveis antropometricas estatura (cm), peso corporal (kg), Indice de Massa Corporal (IMC; kg/[m.sup.2]) e tempo de tela (h). A analise estatistica foi realizada com o software Biostat 5.3. Os resultados foram apresentados em media, desvio padrao, frequencia absoluta e relativa simples, sendo considerado um nivel de significancia de 5% (p [less than or equal to] 0,05). Nas meninas houve maior prevalencia
