“…Within this sample, over two-thirds of children exceed the recommended daily Upper Limit with an average salt intake of 6?0 g/d (103 mmol Na/d). These data are comparable to findings from similar small studies completed in young European (27)(28)(29) and US (30) children where Na excretion was approximately 100 mmol/d. In contrast to previous studies (1) , which have reported higher salt intake in boys, we did not find any gender differences in salt intake.…”

Objective: To measure total daily salt intake using 24 h urinary Na excretion within a sample of Victorian schoolchildren aged 5-13 years and to assess discretionary salt use habits of children and parents. Design: Cross-sectional study. Setting: Completed within a convenience sample of independent primary schools (n 9) located in Victoria, Australia. Subjects: Two hundred and sixty children completed a 24 h urine collection over a school (34 %) or non-school day (66 %). Samples deemed incomplete (n 18), an over-collection (n 1) or that were incorrectly processed at the laboratory (n 3) were excluded. Results: The sample comprised 120 boys and 118 girls with a mean age of 9?8 (SD 1?7) years. The average 24 h urinary Na excretion (n 238) was 103 (SD 43) mmol/24 h (salt equivalent 6?0 (SD 2?5) g/d). Daily Na excretion did not differ by sex; boys 105 (SD 46) mmol/24 h (salt equivalent 6

“…Although there is no fully accepted method to characterize hydration status, FWR may be recommended to define 24-h hydration status (23), and previous studies also revealed that FWR values may be affected by the quality of the diet (24,25). Montenegro-Bethancourt (2013) provided, for the first time, evidence for an association between fruit and vegetables intake and children hydration status.…”

Introduction: Children have an increased risk of voluntary dehydration especially during physical activity which may increase the risk of non-compensating water losses. Objectives: The aim of this study was to assess the hydration status and its relation to food intake in a children group of soccer players. Method: A sample of 36 boys aged 9-10 years was included in this study; 30 completed a 24 h urine collection. Participants completed a 24 h urine collection; a 24 hours food recall corresponding to the day of urine collection was applied, weight and height were measured and parents/caregivers fi lled a lifestyle and socio-demographic questionnaire. The free water reserve (FWR [ml/24 h] = urine volume [ml/24 h] -obligatory urine volume [ml/24 h]) was used to assess the hydration status. Food and beverage groups were created and models of unconditional logistic regression were fi tted in order to estimate the magnitude of the association between the hydration status and diet. Results: Forty three per cent of participants were classifi ed as at risk of hypohydration. Children who reported a high fruit and vegetables intake (above the median) were at decreased risk of hypohydration (OR = 0.19, 95% CI 0.04-0.94, p = 0.041), compared to children who reported a low fruit and vegetables intake. Conclusions: Almost half of the children were at risk of hypohydration. Our results suggested that water food sources such as fruit and vegetables may contribute to euhydration.
