Resumo: Childhood obesity is a prevalent condition in modern societies which can negatively impact people’s health during life. Although there are several factors contributing to obesity, sleep duration has been pointed out as an important risk factor. This study, held in the district of Porto, Portugal, aimed to analyze the association between sleep duration and the nutritional status of school-aged children studying in Portugal. 1396 students from 35 and 3 public and private schools, respectively, were contacted, of which 829 participated in this study (9.2±0.38 years old; 50.3% male; 49.7% female). Age, sex, sleep duration, height, weight and body composition were registered trough a questionnaire. According to the obtained z-score for Body Mass Index (BMI), 22.9% of the children were overweight and 15.2% were obese. The mean of sleep duration was 9.7±1.08 hours and z-score for BMI was 0.78±1.21, demonstrating a statistically significant (p<0.01) weak negative correlation (r=-0.15) between sleep duration and z-score of BMI. Results were also stratified and analyzed by sex, and the same finding was observed. Therefore, the results suggest a negative association between sleep duration and overweight/obesity in these children. Although more studies are necessary, this finding highlights the need of a global approach which includes sleep assessment and counselling when promoting an appropriate nutritional status.

Apesar de serem vários os fatores que contribuem para a obesidade, a duração do sono tem sido apontada como um fator de risco importante. Este estudo, realizado no distrito do Porto, em Portugal, teve como objetivo analisar a associação entre a duração do sono e o estado nutricional de crianças em idade escolar. De 35 escolas públicas e 3 privadas, foram contactados 1396 alunos, dos quais participaram 829 crianças (50,3% meninos e 49,7%meninas) com uma idade média de 9,2±0,38 anos. Através de um questionário, registou-se a idade, o sexo da criança, o número de horas de sono, a altura, peso e composição corporal. Tendo por base os valores obtidos do z-score de Índice de Massa Corporal (IMC), 22,9% das crianças apresentou excesso de peso e 15,2% obesidade. A duração média do sono diário foi de 9,7±1,08 horas e a média do z-score de IMC foi de 0,78±1,21, tendo-se observado uma correlação negativa baixa (r=-0,15) mas estatisticamente significativa (p<0,01) entre a duração do sono e o z-score de IMC. Os dados foram ainda analisados por sexo, tendo-se observado o mesmo achado. Os resultados sugerem, assim, uma associação negativa entre a duração do sono e o excesso de peso/obesidade nestas crianças. Apesar de serem necessários mais estudos, este achado reforça a necessidade de uma abordagem global, que inclua a avaliação do sono e o aconselhamento sobre o mesmo(AU).Centro Universitário São CamiloVeritati - Repositório Institucional da Universidade Católica PortuguesaMarques, GoretiMatos, MariaAfonso, ClaúdiaConceição, Ana Paula daMartins, TâniaPinto, SaraFestas, ConstançaPinheiro, Ana Rita2019-01-22T15:51:58Z20182018-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.14/26738engMarques, G., Matos, M., Afonso, C., Conceição, A.P., Martins, T., Pinto, S & Festas, C.
