“Domestic water fluoridation was associated with an increased risk of PTB (9545 (6.34%) PTB among women exposed to domestic water fluoridation versus 25278 (5.52%) PTB among those unexposed, p < 0.0001)). This relationship was most pronounced among women in the lowest SES groups (>10% poverty) and those of non-white racial origin. Domestic water fluoridation was independently associated with an increased risk of PTB in logistic regression, after controlling for age, race/ethnicity, neighbourhood poverty level, hypertension, and diabetes.”

The study data came from the New York Statewide Planning and Research Cooperative System, which collects comprehensive information on patient characteristics and treatment history. The research was conducted within the State University of New York’s Department of Epidemiology and Biostatistics, School of Public Health.

The applicability of this research to New Zealand Maori in particular is obvious.

Research in Chile in the 1970s showed that fluoridation increased infant death rates. Chile stopped fluoridation as a result.
