Background: Water is essential for maintaining the functions of human body properly. Studies have shown that the amounts and contributions of fluids were associated with health and hydration status. The objectives of the study was that to explore the differences of water intake pattern and hydration biomarkers among young males and females in different hydration statuses.
Methods: A cross-sectional study was implemented among 159 young adults aged 18-23 years in Hebei, China. The total drinking fluids and water from food were obtained by 7-day 24-h fluid intake questionnaire and duplicate portion method, respectively. The osmolality and electrolyte concentrations of the 24h urine and plasma were tested. Differences in optimal hydration (OH), middle hydration (MH) and hypohydration (HH) groups, divided by the osmolality of 24h urine, were compared.
Results: Totally, 156 participants (80 males and 76 females) completed the study. OH group had highest proportions of participants met the recommendations of TWI (total water intake) and total drinking fluids of China (34.5%, 36.2%), while HH group had lowest (7.7%, 0.0%). OH group had higher amounts of TWI, total drinking fluids, water and lower amounts of SSBs (sugar-sweetened-beverages) (p<0.05). The percentage of total drinking fluids in TWI decreased from 54.1% in OH group to 42.6% in HH group (p<0.05). OH group had higher and lower contributions of water and SSBs (sugar-sweetened-beverages) to total drinking fluids (p<0.05); produced 551~950 mL more, excreted significantly less quantity of solutes of urine (p<0.05). No significant differences were found in plasma osmolality among the three groups (p>0.05). Among both males and females, the amounts of TWI and water were higher in OH group than others (p<0.05). Males had 4.3% lower, 5.4% and 1.1% higher contributions of milk and milk products, SSBs and alcohol to total drinking fluids than females (p<0.05); males had higher volume of urine than females only in MH group (p<0.05). There were no significant differences of plasma osmolality between males and females in the same group (p>0.05).
Conclusions: Young adults with optimal hydration status had better water intake pattern and less concentrated urine. Females maybe have better water intake pattern than males.
