The purpose of this study was to verify the correlation analysis between fluid intake on skin hydration and pH of college students.
The subjects were 129 female nursing students in D city. Data were collected by a self-administered questionnaire, using a skin moisture checker and skin pH meter on faces, hands, and feet. The collected data were analyzed by descriptive statistics, t-test, ANOVA, and Pearson correlation analysis, using SPSS WIN, 20.
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 the three body parts according to pure water, caffeinated beverages, and non-caffeinated beverages; however, there was no significant difference measured by fluid intake. There was a 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.
The results suggest that fluid intake, pure water, caffeinated beverages, and non-caffeinated beverages have an effect on skin hydration and pH. Therefore, it is good to increase the amount of fluid intake but, it is recommended to increase the amount of intake of pure water rather than beverages to improve skin status.
Key Words: Drinking water, Beverage, Skin hydration, Skin pH, Nursing student
