Abstract: (9080 Views)
Introduction: Water is an essential nutrient for life. It comprises 75% of total body weight in infants,60% in adult males and 50% in adult females. Decrease in body water is commonly known as dehydration. Acute or chronic dehydration is a common condition in some population groups, especialy the elderly and those who participate in physical activity in warm enviroments. Potential consequences of dehydration include constipation,urinary tract and respiratory infection,urinary stone disease and there might also be an association between a low habitual fluid intake and some carcinomas,cardiovascular disease and diabetes. Many indices have been investigated to establish their role as markers of dehydration status. Body mass changes,blood indices,urine indices and bioelectrical impedance analysis have been used most widely, but current evidence and opinion tend to favour urine indices as the most convenient and sensitive methods.
Methods: This cross sectional study was done for estimating the prevalence of dehydration in adult population(students,nurses,officials,workers)in Yazd. These persons were selected randomly. Urine samples of two hundred and thirty persons were obtained at 10-12 AM,and urine specific gravity measured by refractometer (all of the samples)and dip stick (some samples).
Finding: According to this study,96.7% of our population had some degree of dehydration.69.7% of them were significantly dehydrated(urine SG>1020) and 4.8% of them were severely dehydrated (urine SG>1030) and the mean specific gravity was 1021±5/65. This study evaluated other factors that could probably indicate hydration status like urine colour, type of drink,frequency of urination and frequency of thirst per day.
Conclusion: High percentage of our population were dehydrated which was not correlated to the type of drink but was correlated to urine colour, frequency of urination and frequency of thirst. So, regular monitoring of urine to keep if clear or light yellow is a simple way to prevent dehydration.
