The importance of maintaining an adequate hydration status and the complexity of the water balance make it necessary to study the lifestyle factors that can influence or modify these variables. The aim of this study was to evaluate the hydration status and dietary water intake for a sample of Spanish schoolchildren from 7 to 12 years old and their associations with physical activity PA and sedentary behaviors. A total of schoolchildren was studied In addition, a 3-day dietary record was completed to evaluate their water intake according to EFSA parameters. Student's t-test was used to study the normal variables, and the Mann-Whitney U test was used for those that were not normal.

Competing interests: I have read the journal's policy and the authors of this manuscript have the following competing interests. Water is practically essential for all of the functions of our bodies. Its regulation is based on a complex endocrine system that balances its intake through food, beverages and metabolic water production and loss through skin, sweat, lungs, urine and feces [ 1 ].

The amount lost in urine depends on water consumed, the solute content of diet high intakes of salt or protein will increase the daily fluid replacement because of the limited capacity of the kidneys to concentrate urine and on the total losses [ 2 ].

Equally, the body cannot store excess water, so the kidneys get rid of any temporary excess by producing a large volume of dilute urine [ 4 ]. Adequate hydration in schoolchildren can be related to better performance at concentration tasks [ 5 ] and better physical performance [ 4 ], especially in hot environments [ 6 ].

Healthy children may also be at risk of dehydration if there is a sudden increase in water loss for any reason, and physically active children will be at particular risk during periods of warm weather. In this situation, an increased rate of evaporative cooling is achieved at the expense of an increased loss of water from the body [ 4 ].

Additionally, American College of Sports Medicine [ 8 ] also recommends thirst or urine color scales and plasma osmolality. In our study, thirst scales have not been considered appropriate because of the complexity of filled the questionnaire by parents through the impressions of children. Urine color scales have not been taking into consideration to evaluate the hydration status due to the lack of facilities in our study circumstances to realize an assessment of the urine sample by trained professionals on-site, who realized the anthropometry.

Plasma osmolality is also an excelled standard, but it could be considered an expensive and invasive method [ 9 ] and urine osmolality has been considered a valid and reliable indicator of hydration status and could be used in field settings [ 10 ]. For this reason, urine analysis has been chosen as a practical, fast and less expensive method [ 11 ]. The dynamicity of the water balance makes it especially important to study factors that may modify it; physical activity PA and sedentary behaviors can be included among these factors [ 12 , 13 ].

Regarding the role of inadequate hydration in PA, Stachenfeld et al. In this sense, the sweat volume produced during PA practice directly affects the hydration status [ 15 ]. Despite the massive amount of knowledge about the physiological inter-regulation between these factors, very few studies have evaluated the hydration status in schoolchildren who maintain active lifestyles and perform PA for recreational purposes and in an unplanned manner [ 16 ].

Assessing physical activity behaviors in children is a complex issue. Sedentary leisure behaviors are gaining notoriety among the lifestyle factors. Currently, sedentary behaviors are considered an independent factor of PA that could be interacting with dietary and hydration patterns.

Very few studies relate certain sedentary behaviors to different intake of food and beverages in a quantitative or qualitative manner. This interaction could affect the hydration status. Therefore, we consider it especially interesting to study dietary habits, PA and sedentary behaviors in order to quantify the influence of lifestyle factors on hydration. The aim of the present study was to evaluate the hydration status and dietary water intake in a sample of 7- to year-old schoolchildren and their association with different lifestyles according to their PA and sedentary behaviors.

The design, recruitment of subjects, and methodology regarding anthropometry and urine analysis have been described elsewhere already [ 20 ]. All schools were chosen randomly, looking to include children from different locations of the Spanish geography.

Permission was requested to meet the parents of children in the age group 7—12 years. Once permission was given, the details of the study were explained to parents and all questions answered. Written informed consent was then sought to include their children in the study [ 20 ]. After this step, lifestyle information and a 3-day dietary record were collected, and the necessary material to collect hour urine samples h was provided. A total of 1, children was given the opportunity to participate in the study.

Of these, children provided written informed consent; 16 were excluded because they did not collect the urine sample correctly and 20 were excluded because they did not fully complete the lifestyle questionnaire.

The final sample, therefore, compromised from 7 to 12 years old; The fieldwork was performed between February and March , when the average temperatures were In addition, the participants had received no pharmacological treatments in the 3 months prior to the study with corticosteroids, insulin or diuretics. All measurements took place at the schools in the mornings and in accordance with norms set out by the WHO World Health Organization [ 21 ].

The weights and heights were measured using a digital electronic balance range 0. A lifestyle questionnaire [ 23 ], previously applied in other Spanish populations of children and adults [ 24 , 25 , 26 ], was filled out by the parents or legal guardians S1 Appendix. The questionnaire included questions to quantify the primary activities that could indicate an active lifestyle and sedentary behaviors, both on weekdays and weekends.

This questionnaire collected the frequency of active play, physical activity as a subject in school, extracurricular physical activities and the time spent on each activity. Parents, legal guardians or caregivers of schoolchildren collected this information through active observation except for physical activity as subject in school and extracurricular physical activities.

In the last two cases teachers provided the information. In the case of active plays, information provided by schoolchildren on the activities carried out during the break has also been taken into account. When all of the information was collected, the reported mean of PA hours per week was calculated activities that increase the energy expenditure above the BMR Basal Metabolic Rate according to the Compendium of Physical Activities [ 27 ].

These activities included: active play, PA performed in school and extracurricular physical activities and sedentary behaviors hours spent in front of the PC personal computer , video game console and TV television. Parents or legal guardians filled out a dietary record [ 30 ] about the consumption of food and beverages by the schoolchildren over 3 days 2 weekdays and 1 weekend day.

The days chosen to collect the information were Thursday and Friday as weekdays and Sunday and weekend day. The questionnaire collected the amounts of food and beverages consumed and the time of each intake. In the case of lunch on weekdays that was not consumed with parents, the information collected was checked against the menus provided by school catering service. Once collected, the data were processed in DIAL software for nutritional assessment [ 31 ].

Specifically, water as a beverage is defined as water in the form of tap water, mineral water and sparkling mineral water. A hour urine sample was collected on a weekend day, and it coincided with the dietary record. All of the participants received written instructions and individual containers for the correct collection of the sample.

The volume as well as the urinary urea [ 33 ], sodium, potassium [ 34 ] and creatinine [ 35 ] were determined. To confirm appropriate collection of h urine, the correlation between urinary levels of creatinine and muscular mass of each subject was taken into account. Fat-free mass was calculated bearing in mind the creatinine excreted over 24 h in urine using the following equation [ 36 ]:. The Kolmogorov-Smirnov test was used to test the normality of the variables.

For the categorical variables, the Z and Chi-Square proportion tests were used. To evaluate the influence of the lifestyles, a 2-way ANOVA was performed on the urinary osmolality and different biochemical parameters, and the water dietary intake and beverages were explored with a post hoc Bonferroni analysis. In addition, the OR adjusted by sex and the OR adjusted by sex and other lifestyle factors were calculated.

The sample description is shown in Table 1. Table 2 shows a description of the different parameters related to hydration and the dietary water intake studied here. We performed a linear regression analysis to analyze the risk of dehydration considering all these variables. On the other hand, water intake was not associated to the risk of dehydration. In the sedentary groups, creatinine and sodium excretion was higher.

Table 4 shows crude and adjusted ORs that relate different aspects of lifestyle to the risk of dehydration. The h urine osmolality result was similar to that in other studies, in schoolchildren, as performed using the same methodology in different countries such as France [ 38 ], Egypt [ 39 , 40 ], Greece [ 41 ], Portugal [ 42 ] and the United States [ 43 ].

We found that males had higher osmolality values than females. There are some factors that could explain these disparities between males and females. First, males show higher intake of food and energy, while females show higher intake of water-dense food, specifically fruits and vegetables [ 45 , 46 , 47 ]. Females also have a lower protein [ 48 ], sodium, potassium and phosphorus [ 49 ] intake and, consequently, lower total consumption of solutes.

Additionally, the different PA patterns between the sexes could play a significant role on these disparities; before and after puberty, males also show a higher PA and higher non-renal water losses [ 44 , 50 ].

Sodium intake can also influence hydration status since the excretion of sodium excess requires the excretion of water. The best method to assess sodium intake is to measure the excretion of sodium in urine for 24 hours. Urea excretion is also higher in IH, suggesting a higher protein intake.

And finally, although water intake was similar in both IH and AH children, the former had also lower diuresis, which suggest that IH children could have higher extra-renal losses of water. This difference could be based on the disparity between methodologies used to collect dietary water intake information. Ishii et al. Yamamoto-Kimura et al. However, adherence to PA guidelines may be a risk factor for IH if the water intake does not increase proportionally to the losses associated with higher PA in the case of our study, there are no differences in the water intake depending on the lifestyle.

Additionally, other socioeconomic factors such as accessibility to beverages may also be influence on the hydration status, so they have to be considered as other potential risks of IH. As far as we know, the effects of compliance with the PA guidelines on the state of hydration in schoolchildren have not been evaluated. These data highlight the importance of raising awareness about the hydration status in schoolchildren and their environment in which the primary source of hydration should be water as a beverage.

It is especially important when it comes to implementing a strategy to promote the performance of PA, with nutritional education playing a key role.
