Fluid intake habits among school children in Madrid depend on the educational level of their parents.

Introduction: Several studies show the influence of educational level of parents in their children’s habits, including their fluid intake. 
Objective: To evaluate fluid intake by of school children of the Community of Madrid, differing according to educational level of their parents. 
Method: 564 schoolchildren (258 boys and 306 girls) aged 9-12 years, were studied. Data on fluid intake was obtained by applying a food intake record (3 days). Educational level of parents was self-declared, and it was classified depending on the type of studies completed (low, medium or high). Statistical data was obtained using SPSS (v 19.0) and it was set as statistical significance at p<0.05. 
Results: Children with mothers with higher educational level (medium or high) take more liquid (1,562.4±406.9 and 1,565.7±371.9 mL/day, respectively) than those whose mother′s educational level is lower (1395.04±367.5 mL/day) (p<0.001). It occurs similarly in the case of children whose fathers have higher educational level (fluid intake in children whose parents educated middle and upper: 1,538.7±411.4 and 1,606.8±380.5 mL/day, respectively), compared to those whose fathers have low educational level (1,404.7±350.7 mL/day) (p<0.001). Although in all cases fluid intake is below the adequate intakes (IOM, 2005). 
Conclusions: The water supply is below the appropriate in most of children studied. A lower educational level of parents is associated to lower fluid intake in their descendants, so these children need greater care in their patterns of hydration.
