What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a Smart Water Bottle to determine if it helps college students meet their daily water intake. The bottle lights up to remind users to drink more if they haven't reached their daily goal. Participants will also track simple hydration signs, such as thirst levels and morning urine color. This trial suits college students who don't drink enough water daily and have a smartphone for the bottle's app. The goal is to help students develop healthy drinking habits that can last into adulthood. As an unphased trial, this study provides students the chance to enhance their hydration habits using innovative technology.

Will I have to stop taking my current medications?

If you are currently taking diuretics (medications that help remove excess water from the body) or centrally-acting medications (medications that affect the brain and nervous system), you cannot participate in this trial.

What prior data suggests that this smart water bottle is safe for promoting fluid intake in college students?

Research shows that Smart Water Bottles are safe to use. Studies have found that these bottles help people track and increase their water intake, which is crucial because insufficient hydration can lead to health issues. Smart Water Bottles use technology to remind users to drink more water and monitor their consumption.

No reports of harmful effects from using Smart Water Bottles have emerged, and users generally receive them well. Research has not identified any major problems with their use among college students. Users simply need to follow the instructions for the bottle and app. For those considering joining a trial, past studies suggest that the Smart Water Bottle is safe. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Smart Water Bottle for dehydration because it introduces a personalized and interactive approach to staying hydrated. Unlike traditional methods that rely on individuals to manually track their water intake, this innovative bottle uses smart technology to remind users to drink by lighting up when they're behind on their daily fluid goals. Additionally, it connects to a mobile app for easy logging of all fluid intake and self-monitoring hydration status, enhancing user engagement and accountability. This combination of real-time feedback and technology-driven tracking could make maintaining proper hydration more intuitive and effective.

What evidence suggests that the Smart Water Bottle is effective for improving fluid intake in college students?

Research has shown that Smart Water Bottles, which participants in this trial may receive, can help people drink more water. One study found that using a smart bottle increased water intake and made it easier to remember to drink. This technology also led to more frequent urination, suggesting better hydration. The bottles accurately track water consumption, with only a small error of about 0.5 ounces. These findings suggest that Smart Water Bottles can effectively encourage better hydration habits. ^{6 7 8 9 10}

What Are the Treatments Tested in This Trial?

Interventions

• Smart Water Bottle

Trial Overview The study tests if using a 'Smart Water Bottle', which tracks intake and prompts drinking, can help college students meet daily fluid recommendations to form healthier hydration habits.

How Is the Trial Designed?

Group I: Smart Water Bottle Experimental Treatment 1 Intervention

Participants in the intervention group will be prompted by the water bottle to drink (bottle will light up red) whenever they are behind on fluid intake recommendations for the day. The bottle will be linked to a smart phone application that participants will be instructed to download on their personal mobile device, but they will log into this device using a researcher provided username and password. The bottle will encourage male participants to consume 2.5 L and for female participants to consume 2.0 L of fluid. Participants will be asked to use this bottle to consume all water and enter any additional sources of fluid using the mobile application. The intervention group will also be asked to record their daily perceived thirst, first morning urine color, and body mass as a means of self-monitoring daily changes in hydration status, using a provided paper log.

Group II: Control Active Control 1 Intervention

The control group will be asked to go about daily activities as normal. They will not receive the water bottle and will not be asked to track daily measures of thirst, morning urine color, or body mass.

A study involving 30 male American football athletes demonstrated that a smart bottle accurately measures fluid intake during exercise, with no significant difference compared to traditional gravimetric methods.

The smart bottle's measurements were reliable within approximately ±15% of individual fluid intake, making it a useful tool for athletes to track hydration in real-time during outdoor practices.

In a study of 50 male infants aged 0-3 months, both a 2:1 rehydration regimen of WHO-ORS and diluted WHO-ORS were found to be equally safe and effective in correcting hydration status and serum sodium levels.

However, misinterpretation of rehydration instructions led to complications such as hypernatremia and irritability in some infants, highlighting the importance of clear guidance when administering rehydration solutions.

In a study involving 10 healthy male volunteers, participants effectively managed their own intravenous rehydration based on their thirst, demonstrating a strong correlation between thirst scores and plasma osmolality levels.

When given the option to control the volume of fluid, those in the high-volume condition rehydrated significantly more (3060 ml) compared to the low-volume condition (981 ml), suggesting that allowing patients to self-manage their hydration could improve clinical outcomes.
