Abstract The study objective was to measure fluid intake and associations with background characteristics and hydration biomarkers in healthy, free-living, non-pregnant women aged 15–69 years from Hargeisa city. We also wanted to estimate the proportion of euhydrated participants and corresponding biomarker cut-off values. Data from 136 women, collected through diaries and questionnaires, 24h urine samples and anthropometric measurements, were obtained with a cross-sectional, purposeful sampling from fifty-two school and health clusters, representing approximately 2250 women. The mean (95 % CI) 24 h total fluid intake (TFI) for all women was 2⋅04 (1⋅88, 2⋅20) litres. In multivariate regression with weight, age, parity and a chronic health problem, only weight remained a predictor (P 0.034, B 0.0156 (l/kg)). Pure water, Somali tea and juice from powder and syrup represented 49⋅3, 24⋅6 and 11⋅7 % of TFI throughout the year, respectively. Mean (95 % CI) 24 h urine volume (Uvol) was 1⋅28 (1⋅17, 1⋅39) litres. TFI correlated strongly with 24 h urine units (r 0.67) and Uvol (r 0.59). Approximately 40 % of the women showed inadequate hydration, using a threshold of urine specific gravity (Usg) of 1⋅013 and urine colour (Ucol) of 4. Five percent had Usg > 1⋅020 and concomitant Ucol > 6, indicating dehydration. TFI lower cut-offs for euhydrated, non-breast-feeding women were 1⋅77 litres and for breast-feeding, 2⋅13 litres. Euhydration cut-off for Uvol was 0⋅95 litre, equalling 9⋅2 urine units. With the knowledge of adverse health effects of habitual hypohydration, Somaliland women should be encouraged to a higher fluid intake.

Free Living

It is difficult to describe hydration status and hydration extremes because fluid intakes and excretion patterns of free-living individuals are poorly documented and regulation of human water balance is complex and dynamic. This investigation provided reference values for euhydration (i.e., body mass, daily fluid intake, serum osmolality; M ± SD); it also compared urinary indices in initial morning samples and 24-hr collections. Five observations of 59 healthy, active men (age 22 ± 3 yr, body mass 75.1 ± 7.9 kg) occurred during a 12-d period. Participants maintained detailed records of daily food and fluid intake and exercise. Results indicated that the mean total fluid intake in beverages, pure water, and solid foods was >2.1 L/24 hr (range 1.382–3.261, 95% confidence interval 0.970–3.778 L/24 hr); mean urine volume was >1.3 L/24 hr (0.875–2.250 and 0.675–3.000 L/24 hr); mean urine specific gravity was >1.018 (1.011–1.027 and 1.009–1.030); and mean urine color was ≥4 (4–6 and 2–7). However, these men rarely (0–2% of measurements) achieved a urine specific gravity below 1.010 or color of 1. The first morning urine sample was more concentrated than the 24-h urine collection, likely because fluids were not consumed overnight. Furthermore, urine specific gravity and osmolality were strongly correlated (r2 = .81–.91, p < .001) in both morning and 24-hr collections. These findings provide euhydration reference values and hydration extremes for 7 commonly used indices in free-living, healthy, active men who were not exercising in a hot environment or training strenuously.

Abstract Context: Urine specific gravity (USG) has been used to estimate hydration status in athletes on the field, with increasing levels of hypohydration indicated by higher USG measurements (eg, greater than 1.020). Whether initial hydration status based on a urine measure is related to subsequent drinking response during exercise or athletic competition is unclear. Objective: To determine the relationship between pregame USG and the volume of fluid consumed by players in a professional basketball game. Design: Cross-sectional study. Setting: Basketball players were monitored during Summer League competition. Patients or Other Participants: Players (n  =  29) from 5 teams of the National Basketball Association agreed to participate. Main Outcome Measure(s): Pregame USG was measured for each player on 2 occasions. Athletes were given ad libitum access to fluid during each game and were unaware of the purpose of the study. Volume of fluid intake was measured for each player. To assess sweat loss, athletes were weighed in shorts before and after each game. Results: Sweat loss ranged from 1.0 to 4.6 L, with a mean sweat loss of 2.2 ± 0.8 L. Fluid intake ranged from 0.1 to 2.9 L, with a mean fluid intake of 1.0 ± 0.6 L. Pregame USG was greater than 1.020 in 52% of the urine samples collected and was not correlated with fluid volume consumed during either of the games (r  =  0.15, P  =  .48, and r  =  0.15, P  =  .52, respectively). Conclusions: Approximately half of the players began the games in a hypohydrated state, as indicated by USG. Fluid intake during the game did not compensate for poor hydration status before competition. Furthermore, sweat losses in these players during games were substantial (greater than 2 L in approximately 20 minutes of playing time). Therefore, both pregame and during-game hydration strategies, such as beverage availability and player education, should be emphasized.

The study objectives were to analyze the food and beverages contribution to the total fluid intake, and the sign of mild dehydration of school age children. The cross-sectional study was applied to 78 boys and 78 girls of elementary school students in Bogor City. Two days food recall was applied to estimate fluid intake. The fluid intake was a summation of various food and beverages. The result showed beside of plain water, most of the school children used to consumed milk and tea (&gt;70%) at home. The total fluid intake was 2283 mL for boys and 2024 mL for girls, and its contribution was 21 percent from food (430-490 mL) and 78 percent from beverages (1600-1800 mL). There are 67.4 percent boys and 62.8 percent girls suffered mild dehydration with minimum three physical signs of dehydration. There are still 18.6 percent boys and 3.5 percent girls that their fluid intake below 100% of the requirement.

Connecting The Dots

In the last decade, cross-sectional and multiple cohort studies have associated total fluid intake or water intake with the risk for chronic kidney disease (CKD) and even the risk of developing hyperglycemia. Urine biomarkers have also been linked to the risk of CKD and lithiasis, and these biomarkers respond quickly to variations in fluid intake. High circulating copeptin levels, a surrogate marker of arginine vasopressin, have been associated with metabolic syndrome, renal dysfunction and increased risk for diabetes mellitus, cardiovascular disease and death. The aim of this paper was to explore how the various findings on water intake, hydration and health are interconnected, to highlight current gaps in our understanding and to propose a model that links water intake, homeostatic mechanisms to maintain water balance and health outcomes. Since plasma copeptin and vasopressin have been demonstrated to be sensitive to changes in water intake, inversely associated with 24-hour urine volume, and associated with urine biomarkers and fluid intake, vasopressin is proposed as the central player in this theoretical physiological model.

Adequate Hydration

In children, maintaining adequate fluid intake and hydration is important for physiological reasons and for the adoption of healthy, sustainable drinking habits. In the Liq.In7 cross-sectional surveys involving 6,469 children (4–17 years) from 13 countries, 60% of children did not meet the European Food Safety Authority (EFSA) adequate intake for water from fluids. Beyond fluid quantity, the quality of what children drink is important for health. In these surveys, the contribution of sugar-sweetened beverages and fruit juices to total fluid intake (TFI) in children exceeded that of water in 6 out of 13 countries. To assess the adequacy of children’s fluid intake, urinary biomarkers of hydration such as urine osmolality, urine specific gravity, and urine color may be used. To date, while there are no widely accepted specific threshold values for urine concentration to define adequate hydration in children, the available literature suggests that many children have highly concentrated urine, indicating insufficient fluid intake. This is worrisome since studies have demonstrated a relationship between low fluid intake or insufficient hydration and cognitive performance in children. Furthermore, results of the Liq.In7 surveys showed that at school – where children spend a significant amount of time and require optimal cognitive performance – children drink only 14% of their TFI. Consequently, it is pertinent to better understand the barriers to drinking water at school and encourage the promotion of water intake through multicomponent interventions that combine educational, environmental, and behavioral aspects to support adequate hydration as well as optimal cognition in children.

Fortification with the essential trace element iodine is widespread worldwide. In the present study, results on iodine excretion and intake of iodine-rich foods from a cross-sectional study carried out in 2004–5, 4 to 5 years after the implementation of mandatory iodine fortification, were compared with data in a study carried out in 2008–10. The 2008–10 study was a follow-up of a cross-sectional study carried out before iodine fortification was implemented. Participants in the cross-sectional studies were randomly selected. Both studies were carried out in the cities of Aalborg and Copenhagen in Denmark. The median urinary iodine concentration decreased in women from 97 μg/l (n 2862) to 78 μg/l (n 2041) (P< 0·001). The decrease persisted after adjustment for age, city and education, and if expressed as estimated 24 h iodine excretion. The prevalence of users of iodine containing dietary supplements increased from 29·4 to 37·3 % (P< 0·001). The total fluid intake increased in women (P< 0·001), but the intake of other iodine-rich foods did not change. The median urinary iodine concentration did not change in men (114 μg/l (n 708) and 107 μg/l (n 424), respectively), while the total fluid intake decreased (P= 0·001). Iodine content was measured in milk sampled in 2000–1 and in 2013. The iodine content was lower in 2013 (12 (sd 3) μg/100 g) compared with that in 2000–1 (16 (sd 6) μg/100 g) (P< 0·001). In conclusion, iodine excretion in women has decreased below the recommended level. The reason might probably, at least partly, be a decreased content of iodine in milk.

Objective: To assess the magnitude and associated factors of timely initiation of breastfeeding among cesarean section delivered mothers. Methods: A health facility-based cross-sectional study was employed among 421 systematically selected mothers from February to June, 2017. Data were collected by a structured questionnaire. Data entry and analysis was done using Epi Data and SPSS version 24. Binary logistic regression was computed to identify factors. Adjusted odds ratio with a 95% confidence interval was used to declare statistical significance. Result: The magnitude of timely initiation of breast feeding (among mothers who gave birth by cesarean section was 57%. Counseling during antenatal care (AOR = 3.32; 95% CI: 1.80, 6.13), facility where cesarean section (CS) was performed (AOR = 2.55; 95% CI: 1.57, 4.14), and post-CS counseling (AOR = 6.93; 95% CI: 3.99, 12.02) were factors that contributed for the practice of timely initiation among cesarean section delivered mothers. Conclusions: The magnitude of TIBF was good. Counseling during ANC, the facility where CS was performed and post-natal advice were factors associated with TIBF. Implementation of baby-friendly hospital initiatives should be strengthened in order to promote timely initiation of breast feeding.

Abstract Background The early postnatal period is a dangerous time for both mother and baby where morbidity and mortality are highly prevalent if proper care is not done. Post natal care (PNC) knowledge has significant role in reducing such complications. In this study, the knowledge of postpartum mothers on PNC and its determinants were determined. Methods A cross-sectional quantitative study was conducted in postpartum mothers (PpM) who attended all maternal delivery services in Asmara. Data was collected by a structured questionnaire. All (n = 250) PpM who gave birth in December, 2017 were included in the study. Independent samples t-test and one way ANOVA were used to compare the scores in knowledge across categories of background characteristics using SPSS. Bonferroni post-hoc test was performed for variables that were found to be significant while using ANOVA tool. P-values less than 0.05 were considered as significant. Results The percentage of PpM who cited vaginal bleeding, as a maternal danger sign, and fever, as a baby danger sign, were 83.2 and 58.8%, respectively. The majority (96%) of PpM responded the correct answer on where to go if they note any danger signs. In addition, more than nine tenth of PpM correctly identified injectable contraceptives (92.7%) and oral contraceptive (91.5%). The percentages of knowledge in recognizing the necessary nutrients ranged from 87.6% for carbohydrates to 46% for minerals. The percentages of correct knowledge regarding first baby bath, frequency of breast feeding, umbilical care, duration of exclusive breast feeding, need and purpose of vaccine were 40.1, 81.9, 77.4, 94.8, and 99.2% respectively. The mean PNC knowledge score was 24.89/60. The score of knowledge on postnatal care was found to significantly differ across the categories of residence (p < 0.001) and ethnicity (p = 0.015). An increasing trend of knowledge score was observed with increase in age group (p < 0.001), educational level (p = 0.021), gravida (p < 0.001) and para (p < 0.001). Conclusion Considerable gaps in knowledge regarding postnatal care among postpartum mothers were evident. Special attention should be laid on rural residents, single/living together, junior/below in educational level, primigravida/para, non-Tigrigna ethnicity, and 17 to 25 years old mothers.

Context: The behaviors and beliefs of recreational runners with regard to hydration maintenance are not well elucidated. Objective: To examine which beverages runners choose to drink and why, negative performance and health experiences related to dehydration, and methods used to assess hydration status. Design: Cross-sectional study. Setting: Marathon registration site. Patients or Other Participants: Men (n = 146) and women (n = 130) (age = 38.3 ± 11.3 years) registered for the 2010 Little Rock Half-Marathon or Full Marathon. Intervention(s): A 23-item questionnaire was administered to runners when they picked up their race timing chips. Main Outcome Measure(s): Runners were separated into tertiles (Low, Mod, High) based on z scores derived from training volume, expected performance, and running experience. We used a 100-mm visual analog scale with anchors of 0 (never) and 100 (always). Total sample responses and comparisons between tertile groups for questionnaire items are presented. Results: The High group (58±31) reported greater consumption of sport beverages in exercise environments than the Low (42 ± 35 mm) and Mod (39 ± 32 mm) groups (P &lt; .05) and perceived sport beverages to be superior to water in meeting hydration needs (P &lt; .05) and improving performance during runs greater than 1 hour (P &lt; .05). Seventy percent of runners experienced 1 or more incidents in which they believed dehydration resulted in a major performance decrement, and 45% perceived dehydration to have resulted in adverse health effects. Twenty percent of runners reported monitoring their hydration status. Urine color was the method most often reported (7%), whereas only 2% reported measuring changes in body weight. Conclusions: Greater attention should be paid to informing runners of valid techniques to monitor hydration status and developing an appropriate individualized hydration strategy.
