About this study
The purpose of this exploratory cross-sectional investigation is to evaluate associations between tap water perceptions, water consumption behaviors, and hydration status in Latinx adults (18 - 65 y). The objective is to identify perceptual determinants that explain the associations between tap water avoidance and plain water intake and hydration status in Latinx adults.
Aim 1: Characterize the degree to which individual- and community-level factors uniquely predict the perception that tap water is not safe in Latinx adults.

Aim 2: Evaluate household income, education level, and US nativity as potential moderators of the associations between predictors and perceptions of tap water safety.
Aim 3: Evaluate the influence of tap water safety perceptions on plain water intake and 24-h hydration status, after adjustment for predictors of tap water safety perceptions, in a sub-sample of Latinx adults.

What is being measured
The primary outcome is the main question the study is designed to answer.
Perception of tap water safety
This will be measured via the question "What is your level of agreement with the following statement: My tap water is safe to drink." Possible responses include strongly disagree, disagree, agree, or strongly agree.
