Fluids intake, volume of urine and hydration status among male college athletics in one university of Beijing in spring / 中国学校卫生

ABSTRACT

Objective@#To investigate and analyze the fluids intake, urine output and hydration status during spring among male college athletics from one university in Beijing, and to provide scientific evidence for launching targeted health education.@*Methods@#A simple random sampling method was used to select 109 male students in college with habit of exercise.Total drinking fluids was assessed by 7-day 24-hour fluid intake questionnaire. The water from food was assessed by the duplicate portion method and the weight method. The urine samples of 24-hour was collected for 3 consecutive days, and the volume, osmolality and specific gravity of urine were measured. The energy expenditure in exercise was estimated by using the exercise plan.@*Results@#The median drinking fluids intake, water from food, total fluids intake and urine volume were 1 789, 955, 2 701, 850 mL/d, respectively. 15.6% of the subjects were in proper hydration status, and 43.1% of the subjects were in dehydration. The differences between drinking fluids intake, water from food, total fluids intake and urine volume of subjects in the different BMI and BF% levels were not significant(P>0.05). The differences between drinking fluids intake and total fluids intake of subjects in the different energy expenditure in exercise levels were significant(χ2=9.20, 8.43, P<0.05).@*Conclusion@#Comparing with the normal college students, the drinking fluids intake and total fluids intake of male sports people were higher, the volume of urine was lower, and the hydration status was worse. The targeted health education about water intake was recommended.
