Association Between Daily Water Intake and 24-hour Urine Volume Among Adolescents With Kidney Stones

Adequate hydration is essential for maintaining health and functionality of the human body. Studies assessing both daily water intake and hydration status are lacking. This study explored data from the European Hydration Research Study (EHRS) and focused on total water intake (TWI), 24 h hydration status, and day-to-day variations in a sample of 573 healthy adults. TWI was assessed by food records and hydration status (urine osmolality and urine volume) was measured from 24 urine samples collected over seven consecutive days. On all weekdays, mean TWI was higher (p < 0.001 for all days) for the German subjects compared to the Greek and Spanish participants. In 37% of the male and 22% of the female subjects, the individual mean TWI was below the European Food Safety Authority (EFSA) recommendation, with 16% men (4% women) being below the EFSA recommendation on every testing day. Twenty-four hour urine osmolality was lower in women compared to men (595 ± 261 vs. 681 ± 237 mOsmol/kg; p < 0.001). More men (40%) showed a urine osmolality ≥800 mOsmol/kg at least on four days of the study period compared to women (26%) and more participants from Spain (46%) compared to Greece (29%) and Germany (11%). A large number of individuals showed an inadequate hydration status on several days per week, which may have a negative health and cognitive impact on daily life.

Abstract Background Increased hydration is commonly recommended as a preventive measure for women with recurrent acute uncomplicated cystitis (rAUC), but supportive data are sparse. The aim of this study was to assess the efficacy of increased daily water intake on the frequency of rAUC in premenopausal women. Methods 140 healthy premenopausal asymptomatic women drinking less than 1.5 L of total fluid daily (24 hours) and suffering from rAUC (33 episodes in the past year) were randomized to receive, in addition to their usual daily fluid intake, either 1.5 L water daily (water group) or no additional fluids (control group), for 12 months. Assessments of daily water and total fluid intake, urine volume and osmolality, number of urine voids, and occurrence of AUC symptoms and a reminder to notify investigators of any such symptoms were performed at baseline, 6- and 12-month clinic visits in addition to monthly telephone calls. The primary outcome was frequency of rAUC episodes (31 AUC symptom and 3103 CFU/mL of a uropathogen in voided urine) over 12 months. Results Between baseline and 12 month’s follow-up, the water group, compared with the control group, had statistically significant increases in mean daily water intake (1.15 vs. −0.01 L), total fluid intake (1.65 vs. 0.03 L), urine volume (1.40 vs. 0.04 L), and number of urine voids (2.2 vs. −0.2), and a decrease in urine osmolality (−408 vs. −35 mOsm/Kg). The mean number of rAUC episodes in the water group was significantly less than in the control group (1.6 vs. 3.1; odds ratio 0.52, 95% CI 0.46–0.60,  P < 0.0001) (figure shows cumulative sum of AUC episodes over 12 months in both study groups). The mean number of antimicrobial regimens used to treat AUC events was 1.8 in the water group vs. 3.5 in the control group (P < 0.0001). In addition, the mean number of days to first rAUC and the mean number of days between rAUC episodes was longer in the water group compared with the control group (148 vs. 93,  P = 0.0005 and 143 vs. 85, P < 0.0001, respectively). Conclusions Our results provide strong evidence that increased water intake is an effective antimicrobial-sparing preventive strategy for women with rAUC. Increasing daily water intake by approximately 1.5 L reduced rAUC episodes by 48% and antimicrobial regimens by 47% over 12 months. Disclosures M. Vecchio, Danone Research: Employee, Salary. A.

Abstract Daily water intake (DWI) is essential for survival in humans; however, accurate assessment of DWI from drinks and beverages (Wdrinks) or food moisture (Wfoods) is difficult as it depends on self-reported intakes that are prone to inaccuracy. Here, we established an objective method to assess DWI components using doubly labeled water (DLW). Deuterium and H218O were orally administered, and the dilution space and elimination rate of 2H and 18O were measured. DWI was calculated from the deuterium turnover corrected for metabolic water production and insensible water absorption from humidity. Wfoods was estimated using dietary record (Wfoods-DR) or calculated from the total energy expenditure assessed by DLW (Wfoods-DLW). The current results underscore Wfoods-DR underestimation using self-reported dietary assessments, which underestimates food intake. This study proposes novel methods for calculating each DWI component using DLW.

The articles on dental caries in children in the August 1974 issue of Pediatrics are interesting and made me think about the following aspect of fluoridation. As far as I can find out, none of the presently available formulas have any fluoride in them. Would it not be a good idea to add an appropriate quantity of fluoride to all the formulas so that we can make sure that babies do get fluoride from birth? Even though a majority of the babies live in areas where the water is fluoridated, the amount of daily water intake (as plain water) in the first six months of life is negligible.

Abstract Weaned angus steers (n = 26; 272.92 + 21.29 kg) were selected to study the effects of weather, predicted daily BW, and DMI on total daily water intake (TDWI) from December 2019 to May 2020 (181 days). Calves were provided with ad libitum access to feed and water, under a monoslope barn, for the duration of the study. In periods of cold stress, cattle were provided with corn stalk bedding within the dry lot, away from the monoslope barn. Measurements of feed and water disappearance were obtained by utilizing an automated feed and water system (Insentec RIC, Hokofarm, Marknesse, Netherlands), where disappearance was assumed to be caused by intake. Calves were weighed every 28 days in order to calculate ADG and therefore predict daily BW for each calf. Daily weather records, including windchill (°C), solar radiation (W/m2), and maximum relative humidity (%), were obtained through the South Dakota Mesonet automated weather station located 3.86 km from where the calves were housed. A linear mixed effects model with both random intercept and slope were used to account for the within subject correlations. Increased TDWI was associated with increased wind chill (0.38-kg per 1°C; P < 0.0001), increased solar radiation (1.04-kg per 1 W/m2; P < 0.0001), and decreased maximum relative humidity (-0.14 kg per 1%; P < 0.0001). For every kg increase in DMI, TDWI increased by 1.07 kg (P < 0.0001). Lastly, for every kg increase in BW, TDWI increased by 0.05 kg (P < 0.0001). Effects of DMI, BW, SRAD, windchill, RHMax were predictive of TDWI in beef calves fed during the winter. This model will be useful for predicting TDWI during the winter months where calves are raised in regions where temperatures are regularly below freezing.

Isoproterenol Infusion

A chronically implanted inflatable balloon was used to produce distension of a left pulmonary vein at its junction with the left atrium in trained conscious dogs. Balloon inflation caused a fall in the amounts of water drunk in response to injection of isoproterenol, infusion of hypertonic NaCl, or overnight water deprivation. There was also a significant increase in heart rate, but arterial, central venous, and left atrial pressures were unaltered. Blockade of the left vagosympathetic nerve prevented the inhibitory action of distension of a pulmonary vein on water intake in response to injection of isoproterenol. In experiments where the balloon was left inflated for 24 h, distension also caused a fall in the spontaneous daily water intake, whereas food intake was unaffected. Despite the fall in water intake, urine flow increased so that the dog went into negative fluid balance. In conclusion, distension of a pulmonary vein at its junction with the left atrium causes reduction in both spontaneous and induced water intake, and this inhibition is not secondary to circulatory changes or fluid retention by the kidney. The action of the receptors concerned may complement the actions of the same or similar receptors on renal function whose effects have been observed previously in acute experiments in anesthetized animals and here for the first time in conscious animals.

Water Supplementation

Increased hydration is recommended as healthy habit with several merits. However, supportive data are sparse. To assess the efficacy of increased daily water intake, we tested the effect of water supplementation on biomarkers in blood, urine, and saliva. Twenty-four healthy Japanese men and 31 healthy Japanese women with fasting blood glucose levels ranging from 90–125 mg/dL were included. An open-label, two-arm, randomized controlled trial was conducted for 12 weeks. Two additional 550 mL bottles of water on top of habitual fluid intake were consumed in the intervention group. The subjects drank one bottle of water (550 mL) within 2 h of waking, and one bottle (550 mL) 2 h before bedtime. Subjects increased mean fluid intake from 1.3 L/day to 2.0 L/day, without changes in total energy intake. Total body water rate increased with associated water supplementation. There were no significant changes in fasting blood glucose and arginine vasopressin levels, but systolic blood pressure was significantly decreased in the intervention group. Furthermore, water supplementation increased body temperature, reduced blood urea nitrogen concentration, and suppressed estimated glomerular filtration rate reduction. Additionally, existence of an intestinal microbiome correlated with decreased systolic blood pressure and increased body temperature. Habitual water supplementation after waking up and before bedtime in healthy subjects with slightly elevated fasting blood glucose levels is not effective in lowering these levels. However, it represents a safe and promising intervention with the potential for lowering blood pressure, increasing body temperature, diluting blood waste materials, and protecting kidney function. Thus, increasing daily water intake could provide several health benefits.
