Children are known to consume various fluids in order to cover their water needs. However the contribution of the different fluid categories to hydration is still unknown in children. PURPOSE: To examine whether various drinking patterns are associated with different hydration levels. METHODS: Two hundred and ten Greek healthy children, 105 girls (height: 1.49±0.13 m, weight: 44.1±12.9 kg, fat: 27.7±7.1%) and 105 boys (height: 1.49±0.14 m, weight: 42.6±12.3 kg, fat: 22.8 ± 7.7%) were asked to collect their urine for 24 hours while conducting normal daily activities during autumn and winter months. They were also instructed to record the fluids they consumed in a diary specially designed for children, for two consecutive days. Urine samples were analyzed for color (Ucol) via an eight‐point scale, urine specific gravity (USG) via a hand‐held refractometer, and urine osmolality (Uosm) via freezing point depression osmometry. Principal components analysis was applied to extract dietary patterns from 9 drinks or drinking groups. Multivariate regression analysis evaluated the associations between the extracted dietary patterns and hydration levels deriving from 24h urine osmolality. RESULTS: Six principal components were extracted from the analysis. Component 1 was mainly characterized by consumption of milk, but not water, component 2 by packaged juice and sugar sweetened drinks (SSD) but not Natural Juice, component 3 by natural juice and rest drinks, component 4 by packaged juice, component 5 by water and milk and component 6 by natural juice and SSDs. Component 5 was inversely correlated with hypohydration (P=0.006), whereas none of the other components was associated with the outcomes. CONCLUSION: A drinking pattern that includes water and milk seems to promote better hydration. Grant Funding Source : Danone Research
