A national cohort study found no link between community water fluoridation and adverse birth outcomes, including birth weight.
The study analyzed nearly 11.5 million singleton births across 677 US counties from 1968 to 1988.
Results showed no statistically significant changes in birth weight or related outcomes following fluoridation.
Secondary outcomes, including low birth weight and gestational length, also showed no association with fluoridation.
The findings support the safety of community water fluoridation during pregnancy and emphasize rigorous evaluation methods.
