    Background: Energy from liquids is one of the most important factors that could impact on the high prevalence of children and adolescents obesity around the world. There are few data on the liquid consumption in Brazil. the aim of this study is to evaluate the volume and quality of liquids consumed by Brazilian children and adolescents and to determine the proportion of their daily energy intake composed of liquids.Methods: A multicenter study was conducted in five Brazilian cities; the study included 831 participants between 3 and 17 years of age. A four-day dietary record specific to fluids was completed for each individual, and the volume of and Kcal from liquid intake were evaluated. the average number of Kcal in each beverage was determined based on label information, and the daily energy intake data from liquids were compared with the recommendations of the National Health Surveillance Agency (Agencia Nacional de Vigilancia Sanitaria-ANVISA), the Brazilian food regulation authority, according to each subject's age.Results: As the children aged, the volume of carbonated beverages that they consumed increased significantly, and their milk intake decreased significantly. for children between the ages of 3 and 10, milk and dairy products contributed the greatest daily number of Kcal from liquids. Sugar sweetened beverages which included carbonated beverages, nectars and artificial beverages, accounted for 37% and 45% of the total Kcal from liquid intake in the 3-to 6-year-old and 7- to 10-year-old groups, respectively. Among adolescents (participants 11- to 17-years old), most of the energy intake from liquids came from carbonated beverages, which accounted for an average of 207 kcal/day in this group (42% of their total energy intake from liquids). Health professionals should be attentive to the excessive consumption of sugar sweetened beverages in children and adolescents. the movement toward healthier dietary patterns at the individual and population levels may help to improve programs for preventing overweight and obesity in children and adolescents.Conclusion: From childhood to adolescence the daily volume of liquid ingested increased reaching a total of 2.0 liters on average. of this volume, the daily volume of milk ingested decreased while the carbonated drinks, sweetened, nectars and artificial beverages increased significantly. the proportion of water remained constant in about 1/3 of the total volume. From 3 to 17 years of age the energy intake from carbonated beverages increased by about 20%. the carbonated drinks on average corresponded to a tenth of the daily requirements of energy of adolescents.

    Hipoidratação em escolares e sua relação com o consumo de água livre e o estado nutricional
    (Universidade Federal de São Paulo (UNIFESP), 2016-06-23) Dias, Francine Canovas [UNIFESP]; Morais, Mauro Batista de [UNIFESP]; http://lattes.cnpq.br/5056114729141952; http://lattes.cnpq.br/2675004258941315; Universidade Federal de São Paulo (UNIFESP)
    Objectives: To assess the prevalence of hypohydration in students according to urine osmolality; to study the relationship between hypohydration and: free water consumption, nutritional status and seasons; and to evaluate the diagnostic value of the use of a urine color scale to characterize hypohydration in students. Methods: A cross-sectional study conducted at two public schools in the city of Osasco, SP. The evaluation of the state of hydration was carried out according to urinary osmolarity adopting the cutoff of 800 mOsm/kg. Results: A total of 475 students were evaluated, 60.4% (N=287) were female and 39.6% (N=188) were male. The overall prevalence of hypohydration in the studied population according to urine osmolality was of 63.1%, of which 40.8% had intense hypohydration and 22.3% had maximum hypohydration. The frequency of hypohydration was higher in males than in females (p =0,007) and was more frequent in winter than in other seasons (29.9%; p=0,002). There was no correlation between the urine color scale and urine osmolality (Kappa=0,04). Hypohydration showed no relation with socioeconomic status, nutritional status and estimated free water consumption. Conclusion: There was a high prevalence of hypohydration in studied students, being more frequent in males and during winter.
