Overview
Approximately 60% of males and 40% of females do not meet current fluid intake recommendations, which is associated with adverse health consequences such as obesity, diabetes, and chronic kidney disease. Newer technologies have been designed to promote fluid intake. "Smart Water Bottles" use mHealth technology to capture fluid intake behaviors automatically and provide cues to encourage fluid consumption. Studies using Smart Water Bottles have helped some individuals increase fluid intake to help reduce kidney stone formation. However, limited research has assessed the efficacy of this technology on improving fluid intake in college students. College is a time with the potential to form healthy habits that carry into adulthood. Previous work has also identified daily changes in morning urine color, thirst perception, and body mass, as simple, inexpensive indicators of daily fluctuations in water balance. Tracking changes in these metrics has the potential to provide participants with evidence of adequate or inadequate fluid consumption. Thus, the combination of prompting from a smart water bottle, as well as daily self-monitoring changes in hydration status, may encourage college students to increase daily fluid consumption.
Interventions
- Behavioral Smart Water Bottle
Participants in the intervention group will receive a bottle which measures participant fluid consumption. The bottle will be set to recommend 2.5L for male participants and 2.0L for female participants, consistent with fluid intake recommendations from the European Food Safety Authority for each sex. Participants will be prompted by the bottle (bottle will light up) when they are behind on fluid intake recommendations. Participants will use a validated urine color chart, 9 point Likert scale fo
Primary outcome measures
