JESUS, Alison Karina de et al. Hydration Status and Main Sources of Water in School Children. Acta Port Nutr [online]. 2017, n.10, pp.08-11. ISSN 2183-5985.  https://doi.org/10.21011/apn.2017.1002.

Introduction: Water is the most abundant constituent of the human body. An adequate hydration prevents various diseases and it is important for the maintenance of a good health. Objectives: We aimed to evaluate the hydration status and the contribution of meals as well as food and beverages groups to the total water intake in a sample of children, aged 7 to 11 years. Methodology: A sample of 199 (97 boys and 102 girls), 7-11 years-old children were included in this study. We evaluated the hydration status from the collection of a 24-hour urine sample and quantified the urinary markers for the calculation of the Free Water Reserve. A 24 h food recall was applied for the period of collection of the urine sample, for further analysis on food contribution to total daily water intake. The contribution of water of each meal was also evaluated. The values of the Free Water Reserve calculation allowed the sample classification in euhydrated children in which Free Water Reserve positive values indicate euhydration and the negative values to hypohydration. The Free Water Reserve and the percentage contribution of food groups and beverages as well as meals were compared by sex, using the Mann Whitney test. Results: Most of the children were classified as being euhydrated (86.4%). The food group that contributed to water intake in boys and in girls was dairy products (23.8% and 25.7% respectively). In terms of meals, lunch is the main source of water intake (38.7%). Girls have healthier choices by choosing water (17%) and fruit (8.8%) rather than soft drinks (6.4%). Conclusions: Most children was euhydrated. Nevertheless it is important to encourage the consumption of foods with higher water content and a more balanced distribution throughout the day.
