School-Based Hydration Intervention for Dental Health and Obesity Prevention

This study is testing a 4-month school-based hydration program to see if it helps improve dental health and prevent obesity in children. The program, called "Hydration," provides refillable water bottles and hydration stations in schools, along with other activities. Researchers will look at how often students use water stations, their dental health (Dental Caries Status), and their Body Mass Index (BMI) over three years. Children in kindergarten through fifth grade who eat lunch at school are eligible for some parts of the study. For BMI and dental assessments, students enroll in 3rd grade and are followed through 5th grade. The study aims to enroll 7200 participants, but its current recruitment status is unclear.

Study design
This interventional study plans to enroll 7200 participants. Groups of schools will gradually receive the hydration program over time.
What's involved
Students will be observed during lunch, and some will have their BMI and dental health assessed. Older students may complete surveys about their drink choices and opinions.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for up to three years to measure water station usage, dental health, and Body Mass Index.

What this trial measures

  • Water Station UsageYears 1-3

    Ounces of water per student per day measured by hydration station flow meters.

  • Dental Caries Statusup to 3 years

    Tooth decay or cavities will be measured using a modified International Caries Detection and Assessment System (ICDAS)

  • Body Mass Index (BMI)up to 3 years

    NHANES Anthropometry methods used to measure height and weight. Age and sex-specific BMIz-score and BMI percentile will be calculated using Epi Info
