The impact of heat stress on the feed intake, milk production, water intake and urine output of undernourished lactating ewes and on the growth rate and water intake of their lambs was measured both in a climate chamber and during exposure to natural high ambient temperature conditions. Similar liveweight increases occurred in both stressed and unstressed lambs. Feed intake was depressed in heat-stressed ewes in the climate chamber but not under natural heat-stress conditions. During the first and second weeks of lactation calculated milk yield (200-500 mljday) and composition were unaffected by heat stress per se. However, undernutrition due to the poor quality roughage offered apparently depressed milk production of all ewes. Increased water intake (27 %) and plasma prolactin concentrations (220 %) were recorded in heat-stressed ewes, but daily urine output (27-36 mljkg body wt) was unaffected. No relationship between prolactin concentrations, milk production and antidiuretic activity was obvious. At the age of 5-6 weeks water intake accounted for 67 % (500 mljday) and 80 % (1000 mljday) of total fluid intake (water plus milk) of unstressed and heat-stressed lambs respectively. These data indicate the importance of making water freely available to lambs subjected to extensive grazing systems of tropical regions.

Objective: To assess the intake of water and all other beverages in children, adolescents and adults. Methods: Three thousand six hundred eleven children (8 ± 2 years), 8,109 adolescents (13 ± 2 years) and 16,276 adults (40 ± 14 years) (47% men) were recruited in 15 cross-sectional surveys (liquid intake across 7 days, Liq.In7 study) and completed a 7-day fluid-specific record to assess total fluid intake (TFI), where TFI was defined as the sum of drinking water and other type of beverages. Results: The median TFI was 1.2, 1.2 and 1.8 liters/day in children, adolescents and adults respectively, with important differences observed between countries. Only 39% of children, 25% of adolescents and 51% of adults met the European Food Safety Authority adequate intake (AI) recommendations of water from fluids. In the surveys of Spain, France, Belgium, Germany, Turkey, Iran, Indonesia and China, water was the major contributor (47-78%) to TFI. In the adult surveys of UK, Poland, Japan and Argentina, hot beverages were the highest contributor to TFI. The fluid intake of children and adolescents in Mexico, Brazil, Argentina and Uruguay was characterized by a contribution of juices and sweet beverages that was as important as the contribution of water to TFI. Conclusion: Given that a relatively high proportion of subjects, especially children and adolescents, failed to meet the recommended AI of water from fluids and that water intake was not the highest contributor to TFI in all countries, undertaking actions to increase water intake are warranted.

Thirty-six lactating New Zealand White rabbit does were divided into 6 groups according to ambient temperature and feed intake. The does were kept at 20 °C during pregnancy and at kindling, then they were put into climatic chambers at temperatures of 5, 15, 23 or 30 °C. One part of the does were fed ad libitum (5A, 15A, 23A and 30A), two other groups were housed at 15 °C, but they received the same amount of pellet as the does' intake at 23 °C or 30 °C (15/23R and 15/30R). The litter sizes were equalized to seven. The weight of does, milk production, feed intake and water intake were recorded daily. Heat stress reduced milk yield (148, 152, 150 and 106 g/day), feed intake (287, 279, 260 and 179 g/day) and water intake (497, 512, 526 and 428 g/day), but increased the water/feed ratio (1.73, 1.84, 2.02 and 2.39) in the groups of 5A, 15A, 23A and 30A, respectively. Body weight of does decreased at 23 °C and 30 °C by 5.6% and 8.5%, respectively, compared to 15 °C. Comparing the groups of rabbits kept at 23 °C and 30 °C fed ad libitum (23A and 30A) and the data obtained for groups of 15/23R and 15/30R it was observed that the milk yield decreased by 8.0% and 2.5%, water intake increased by 8.6 and 13.3%, and the feed/water ratio was higher by 0.18 and 0.18, respectively. The effect of heat stress was less significant on kits than on does. It can be concluded that the high ambient temperature mainly affected the milk production through the reduction of feed intake.

Abstract Objectives To evaluate fluid intake of college students during the initial response to the COVID-19 pandemic. Methods College students (n = 1015 (75.5% Female); 59 freshmen, 139 sophomores, 264 juniors, 245 seniors, 289 graduate) participated in an online questionnaire from colleges/universities within the United States during the Spring 2020 academic semester. Participants were asked about their fluid intake over the previous 30 days using the BEVQ-15. The questionnaire consisted of demographic and living status questions as well as 16 questions detailing type (e.g., water, milk, etc.), frequency (“how often”), and volume of fluids for each consumption (“how much each time”). Kruskal-Wallis analyses (test statistic reported as chi-square, χ2) were used to compare the total fluid intake, frequency of plain water intake, and volume with each consumption between those with and without a change in living situation and by academic standing. Data reported as (median [interquartile range]). Results A change in living status was reported by 426/1015 (42%) participants. Median fluid intake was 1848 mL ([1295, 2532] mL) for all participants. Total fluid intake [χ2(1) = 18.07, P < 0.001] was different between those with (1709 [1199, 2366] mL) and without (1940 [1378, 2644] mL) a change in living situation. However, the volume of plain water intake was not different between those with (710 [473, 1420] mL) and without (1065 [591, 1420] mL) a change in living situation [χ2(1) = 2.81, P = 0.09]. Frequency [χ2(1) = 3.10, P = 0.08] and the volume with each consumption [χ2(1) = 1.16, P = 0.28] of plain water were also not different based on a change in living situation. Academic standing impacted the volume of total fluid intake [χ2(4) = 14.33, P = 0.006], with juniors (1751 [1161, 2455] mL) reporting less than graduate students (1940 [1041, 2780] mL, P = 0.01). Conclusions These data suggest a change in living situation affected total fluid intake, however, there were no differences in the frequency and volume of plain water intake. Further, academic standing impacted the fluid intake behaviors. Future investigations are warranted to evaluate factors guiding fluid intake frequency and volumes in the college student population.

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.

It has been reported that daily fluid intake influences urinary dilution, and consequently the risk of urolithiasis in human subjects and dogs. The aim of the present study was to investigate the role of dietary moisture on urinary parameters in healthy adult cats by comparing nutritionally standardised diets, varying only in moisture content. A total of six cats were fed a complete dry food (6·3 % moisture) hydrated to 25·4, 53·2 and 73·3 % moisture for 3 weeks in a randomised block cross-over design. Urinary specific gravity (SG), urine volume, water drunk and total fluid intake were measured daily; relative supersaturation (RSS) for calcium oxalate (CaOx) and struvite was calculated using the SUPERSAT computer program. Cats fed the 73·3 % moisture diet produced urine with a significantly lower SG (P < 0·001) compared with diets containing 53·2 % moisture or lower. Mean RSS for CaOx was approaching the undersaturated zone (1·14 (sem 0·21); P = 0·001) for cats fed the diet with 73·3 % moisture and significantly lower than the 6·3 % moisture diet (CaOx RSS 2·29 (sem 0·21)). The effect of diet on struvite RSS was less clear, with no significant difference between treatment groups. Total fluid intake was significantly increased (P < 0·001) in the 73·3 % moisture diet (144·7 (sem 5·2) ml, or 30 ml/kg body weight per d) compared with the 6·3 % (103·4 (sem 5·3) ml), 25·4 % (98·6 (sem 5·3) ml) and 53·3 % (104·7 (sem 5·3) ml) moisture diets, despite voluntary water intake decreasing as dietary moisture intake increased. Cats fed the 73·3 % moisture diet had a higher total daily fluid intake resulting in a more dilute urine with a lower risk of CaOx when compared with the lower-moisture diets.

The primary aim of this cross-sectional survey was to assess the total fluid intake (TFI; sum of drinking water and all other fluids) and the intake of water and all other types of beverages in a sample of pregnant and breastfeeding women representative of Java-Island, Indonesia. Therefore, 299 pregnant and 296 breastfeeding women completed a 7-day fluid-specific record. A secondary aim was to estimate the total water intake (TWI; sum of water from fluids and food moisture), and one 24-h recall was performed to determine water intake from food moisture. The median TFI of pregnant and breastfeeding women were 2,250 (1,800-2,800) and 2,360 (1,954-2,968) mL/day, respectively. The largest contributor to TFI was water (72 and 77% for pregnant/breastfeeding women, respectively). Pregnant women to the extent of 42% and 54% of breastfeeding women did not reach the adequate intake (AI) of water from fluids. In pregnant and breastfeeding women, the median water intake from foods was 592 and 613 mL/day, representing 21 and 20% of TWI. Concluding that a high proportion of the pregnant and breastfeeding subjects did not reach the AI of water from fluid, it seems important to put in place actions such as providing education materials and ensuring access to safe water. Moreover, future surveys should dedicate attention to the assessment of fluid intake and hydration status among pregnant and breastfeeding women in other countries.
