Fluoride ingestion is related to fluid consumption patterns.

Area of Science:

• Pediatric Nutrition
• Environmental Health
• Public Health

Background:

• Fluoride intake is crucial for dental health but excessive amounts can be harmful.
• Limited data exists on fluoride intake variations based on fluid consumption patterns in children.
• Understanding these patterns is key to assessing potential health risks.

Purpose of the Study:

• To estimate fluoride intake in U.S. children based on their fluid consumption.
• To identify factors influencing fluoride ingestion levels.

Main Methods:

• Utilized data from the third National Health and Nutritional Examination Survey (NHANES III, 1988-1994).
• Assessed fluid intake (plain water, beverages, water from foods) in children aged 1-10 years via 24-hour recall.
• Estimated fluoride ingestion using assumed concentrations in fluids and applied logistic regression analysis.

Main Results:

• Children in higher percentiles of fluid fluoride intake consumed 0.05-0.07 mg F/kg/day or more.
• Significant variations in fluoride ingestion were observed based on fluid consumption, age, gender, and race/ethnicity.
• African-American children showed significantly higher fluoride intake than White children, even after controlling for confounders.

Conclusions:

• Sociodemographic factors and fluid consumption significantly influence fluoride intake in children.
• Concerns exist regarding higher fluoride ingestion levels in certain pediatric populations.
• Further research is needed to explore these variations and their impact on fluorosis prevalence.
