    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.

  • Peso máximo da mochila recomendado para crianças em contexto escolar: uma scoping review
    Publication . Matos, Maria; Barreiras, Catarina; Festas, Constança
    Objectives: to map the evidence in relation to the maximum backpack weight recommended for children in school context. Methodology: suggested by the Joanna Briggs Institute. The relevance analysis of the articles, the extraction and synthesis of the data was carried out by two independent reviewers. Starting question: what is the maximum backpack weight recommended for children, from 6 to 12 years old, in school context Data sources: primary studies published in scientific databases, international guidelines and gray literature. Summary of the data: 353 publications were identified, of which 28 were included. The recommended weight percentage is divided into two categories: with recommendation (ranging from 5% -20%) and without recommendation. Conclusions: This scoping review allowed to map the evidence in relation to the maximum weight of the backpack recommended for children in school, where the value of 10% was the one that obtained the greatest consensus.
