Water fluoridation in Brazilian cities at the first decade of the 21st century

ABSTRACT OBJECTIVE To assess the coverage of the fluoridation of the public water supply in Brazilian municipalities at the first decade of the 21st century, according to population size and municipal human development index (MHDI). METHODS We have used data produced by national information agencies and the United Nations Development Programme. Population size was separated into < 10,000, 10,000–50,000, and > 50,000 inhabitants. The MHDI was classified into < 0.600, 0.600–0.699, 0.700–0.799, and > 0.799. Absolute and relative inequalities between categories were evaluated using indicators of effect and total impact. RESULTS We have obtained information for 5,558 municipalities. The coverage rate of water fluoridation increased from 67.7% to 76.3%. Approximately 884 (15.9%) municipalities and 29,600,000 inhabitants started being benefited by the measure. We have observed a significant expansion in municipalities with < 10,000 inhabitants (increase of 21.0 percentage points) and low or very low MHDI (17.7 percentage points). CONCLUSIONS Population coverage of the public policy has increased 8.6%, and we can also see significant reductions in absolute and relative inequality according to population size and MHDI. Regarding municipal coverage rate, there was also a reduction in inequality in all comparisons except for absolute inequality between the categories of MHDI. The public policy has operated as a factor of health protection in the context of the ongoing social protection policies in the country.
