Abstract
Background: Dehydration occurs due to the loss of body fluids. Up to 49,5% of adolescent are dehydrated due to their physical activity levels combined with insufficient fluid consumption. Data form the 2014 Indonesian Total Diet Study revealed that the average fluid intake for ages 13-18 years is 1174 ml, meeting only 58,7% of total fluid intake. Dehydration in adolescent can have repercussions on physical fitness, cognitive performance, psychological well-being, particularly mood, thereby potentially affecting productivity
Purpose: This study aimed to investigate how drink intake, body-fat percentage, physical activity related to hydration status of female adolescents
Methods: This cross-sectional study involved 99 participants selected through purposive sampling. Drink intake was assessed using a 7-Day Drink Record method, percent body fat with BIA (Bioelectrical Impedence Analysis), and physical activity with IPAQ (International Physical Activity Questionnaire). The Spearman Correlation Test used to analyze the statistical data.
Results: Of the 62,6% of adolescent experienced the mild dehydration, while 79,8% exhibited a normal. Physical activity was predominantly classified as moderate (91,9%). Drink intake and physical activity were significantly correlated with hydration status (p<0,05- r=0,305)- (p<0,05- r=0,232). However, body-fat percentage did not correlate with hydration status.
Conclusion: Drink intake and physical activity were associated with hydration status while body-fat percentage showed no correlation with hydration status.
