Hydration Status: Influence of Exercise and Diet Quality

Physical activity, adherence to a healthy diet, and healthy beverage pattern are considered essential components of a healthy lifestyle. We aimed to evaluate the associations between physical exercise, diet quality, and total fluid intake, along with fluid recommendations compliance in a sample of adults. Data on fluid intake from different types of beverages were collected in a cross-sectional study, in 1161 men and women between 18 and 65 years of age, using a fluid-specific diary. Exercise was evaluated with a self-reported questionnaire, and quality of diet was assessed using the Healthy Eating Index-2010 (HEI). Mean volume of water consumed was 1497.5 mL for men, 1309.5 mL for women. A total of 37.4% did not follow the recommendations of the European Food Safety Agency for total water intake. There was a statistically significant difference (P = .002) between total water intake and follow-up of recommendations, as well as for sex (P < .001). Mean HEI-2010 score was 65.21. There were no statistically significant differences (P = .301) in HEI index among better or worse hydration. Sport variables had influence on milliliters of water consumed (P < .001). Participants who engaged in more physical exercise exhibit a healthier pattern of fluid intake. Healthy individuals with the highest scores for HEI-2010 did not present the healthiest beverage patterns.
