Purpose: The purpose of this study was to verify the correlation analysis among fluid intake on skin hydration and skin pH of college students. Methods: The subjects were 129 female nursing students in D city. Data was collected between July 28 and August 27, 2014. General characteristics and status of fluid intake were collected by self-administered questionnaire. In questions about status of fluid intake, pure water and 10 different kinds of beverage were included. Data of skin hydration and skin pH were collected by using skin moisture checker and skin pH meter on face, hand, and foot. The collected data were analyzed by descriptive statistics, t-test, ANOVA, and pearson correlation analysis, using SPSS Win, 20 Program. Results: The daily fluid intake was composed of 57% pure water, 21% caffeinated beverages, 22% non-caffeinated beverages. There were significant differences in average skin hydration on three body parts according to pure water, caffeinated beverages, and non-caffeinated beverages; however, no significant difference according to total fluid intake. There was no significant difference in average skin pH on three body parts. There was significant positive correlation between fluid intake and skin hydration: between pure water and skin hydration. There was significant negative correlation between caffeinated beverages and skin hydration: between non-caffeinated beverages and skin hydration. Conclusion: The results of this study suggest that total fluid intake, pure water, caffeinated beverages, and non-caffeinated beverages have an effect on skin hydration and skin pH. Therefore, it is good of increasing amount of total fluid intake but, is recommended to increase the intake of pure water than beverage to improve skin status.
