Relationship between Nutrient Intake Ratio and Sedentary Time of Female Adults by Dehydration Estimated with Blood Urea Nitrogen to Creatinine Ratio: Based on the 2016∼2018 Korea National Health and Nutrition Examination Survey

ABSTRACT

There is a dearth of Korean studies on dehydration, one of the health risks for adult women. This study analyzed the subjects of the 2016∼2018 National Health and Nutrition Examination Survey (KNHANES) to investigate the relationship between nutrient intake ratios and sedentary time in dehydrated women. Body mass index and waist circumference in the dehydrated group (DG) were significantly higher than the normal group (NG). Intake of other liquids in the DG was significantly higher than in the NG, but total water intake in the DG was significantly lower than in the NG. Compared to the 600 sedentary minutes or more per day group, the odds ratio of dehydration was significantly higher in the less than 300 sedentary minutes per day group (1.871 [95% CI 1.579∼2.215], P＜0.001). Compared to the drinking over 6.0 cups of water per day group, the odds ratio of dehydration was significantly higher in the 3 cups or fewer per day (OR [95% CI] is 1.198 times [1.019 to 1.408], P＜0.05), and 6.0 cups or fewer group (OR [95% CI] is 1.162 times [1.018 to 1.326], P＜0.05). The results of this study showed that the total water intake was relatively lower in the ≥600 sedentary minutes per day group compared to the 300 sedentary minutes per day group, making them more vulnerable to dehydration. The nutrient intake ratios were higher in the dehydration group than in the normal group. In conclusion, emphasis should be placed on the importance of hydration and nutrition education for adult women in the workplace.
