Cumprimento das recomendações da OMS sobre tempo de exposição a ecrãs e sua relação com a aptidão física em pré-escolares: projeto piloto SUNRISE em Portugal.

Abstract

Este estudo teve como objetivo analisar a associação entre o cumprimento das recomendações de exposição a ecrãs com a aptidão física (ApF) em pré-escolares. Trata-se de um estudo observacional, transversal e analítico, desenvolvido no âmbito do projeto piloto do SUNRISE em Portugal, com uma amostra de 89 crianças (3-4 anos). Para avaliar a ApF, o índice de massa corporal (IMC) foi calculado a partir das medidas de massa e estatura corporais. Foram realizados os testes Supine-Timed Up and Go, o salto horizontal e a dinamometria manual (direita e esquerda). O tempo de exposição a ecrãs (TE) foi obtido através de questionário preenchido pelos encarregados de educação, categorizando-se as crianças em: cumprem vs. não cumprem com a recomendação de no máximo 1h/dia de exposição a ecrãs. Os dados foram analisados no Statistical Package for the Social Sciences (SPSS), versão 29.0. A normalidade das variáveis foi verificada pelo teste de Kolmogorov-Smirnov e a homogeneidade de variâncias pelo teste de Levene. Para comparar as variáveis contínuas entre os grupos, recorreu-se ao teste T de Student para amostras independentes ou ao teste de Mann-Whitney, consoante a distribuição dos dados. As variáveis categóricas foram analisadas através do teste do Qui-quadrado ou Exato de Fisher. Para avaliar a correlação entre o TE (min/dia) e as variáveis de ApF, foi utilizado o coeficiente de correlação de Spearman. O nível de significância foi fixado em p0,05). De igual modo, não foram encontradas correlações significativas entre o TE e as variáveis de ApF (ρ entre -0,07 e 0,12; p>0,05). Conclui-se que, nas crianças avaliadas, o TE não se associou à ApF. Futuros estudos com amostras representativas devem ser realizados para confirmar estes achados.

This study aimed to analyze the association between compliance with screen time (ST) recommendations and physical fitness (PF) in preschool children. It was an observational, cross-sectional, and analytical study conducted within the framework of the SUNRISE pilot project in Portugal, with a sample of 89 children (3-4 years old). PF was assessed through body mass index (BMI), calculated from body mass and height, as well as the Supine-Timed Up and Go (STuG) test, standing long jump, and handgrip strength (right and left). Daily ST was obtained using a parent-reported questionnaire, categorizing children as meeting vs. not meeting the recommendation of a maximum of 1 hour/day of ST. Data were analyzed using the Statistical Package for the Social Sciences (SPSS), version 29.0. Normality of the variables was verified with the Kolmogorov-Smirnov test and homogeneity of variances with Levene's test. To compare continuous variables between groups, Student's t-test for independent samples or the Mann-Whitney test was applied, depending on data distribution. Categorical variables were analyzed using the Chi-square or Fisher's exact test. To assess the correlation between ST (min/day) and PF variables, Spearman's correlation coefficient was used. The significance level was set at p0.05). Similarly, no significant correlations were found between ST and PF variables (ρ between -0.07 and 0.12; p>0.05). In conclusion, among the children assessed, ST was not associated with PF. Further studies with representative samples are needed to confirm these findings. Keywords:
