Filter by:The goal of this clinical trial is to understand if a cultural intervention for Navajo families will improve healthy beverage habits, health outcomes, and family cohesion. The main questions it aims to answer are: - Does Water is K'é results in healthier beverage habits among children aged 2 to 5, compared with children in a control group? - Does the intervention improve the health of other family members? - How does the intervention affect family well-being? Participants will take part in a four-month program at the early child education site (such as a Head Start or the Bureau of Indian Affair's Family and Child Education or FACE Program) where the child is enrolled. They will take part in lesson plans, a social media campaign, and a family water access plan. Researchers will compare the participating families with families at wait-list early child educations sites. We will collect information through surveys, health measurements, and qualitative interviews and compare results to learn if Water is K'e improves health behaviors, health outcomes, and family cohesion.
Consuming large volumes of water has recently been identified as a common weight loss strategy among U.S. adults. It is a widespread belief that drinking water increases feelings of satiety and reduces food intake, which could contribute to long-term weight maintenance. Many studies have shown support for this, demonstrating water's ability to reduce hunger and energy intake. In some cases, increased water consumption was associated with weight loss. However, the mechanisms of how water affects food intake have been minimally explored. There is potential that the effect of water on reduced food intake and increased satiety is due to individuals' belief that water will reduce their appetite and food intake. The question remains if water expectancy has a meaningful influence on water's ability to reduce food intake. The investigators hypothesize that participants will report less hunger and consume fewer calories when given water and an expectancy that water will affect appetite, compared to a condition when given water and do not expect water to have an effect on appetite. We further hypothesize that calorie intake will not meaningfully differ when participants are given water with no expectancies compared to when given no water. During this experiment, the investigators will vary the presence of water and manipulate expectancies about water's effects on appetite across three conditions: (1) an expectancy and water condition; (2) an expectancy and no water condition; and (3) a no expectancy and water condition. In each condition, participants will engage in a bogus taste test and complete two short cognitive tasks for distraction purposes. In an effort to prevent demand characteristics, this study involves deception. Participants will be told that the research team is interested in testing the effects of three different mint herb variations on attention, coordination, and taste perceptions. After completing the cognitive tasks and taste test, participants will have a 10 minute period to eat as much of the remaining food as they'd like. Food will be weighed before and after this period (without the participant's knowledge) in order to determine caloric intake.
This study will assess whether there is a performance enhancing effect associated with hydrating with coconut water. There have been only two studies in the past that have examined this phenomenon, however these studies have limitations due to their design parameters. Kalman et al. (2012) ".... while treadmill time to exhaustion is routinely used in laboratory studies, the use of a time trial test as the measure of exercise performance may be more appropriate." While Peart et al. (2016) stated: "limitations to the exercise protocol employed here may have contributed to the absence of a performance improvement with coconut water."
