Resumo
The objective of this ecological study was to investigate the association between caries experience in 5- and 12-year-old Brazilian
children in 2010 and household sugar procurement in 2003 and the effects of exposure to water fluoridation and socioeconomic
indicators. Sample units were all 27 Brazilian capital cities. Data were obtained from the National Surveys of Oral Health;
the National Household Food Budget Survey; and the United Nations Program for Development. Data analysis included
correlation coefficients, exploratory factor analysis, and linear regression. There were significant negative associations between
caries experience and procurement of confectionery, fluoridated water, HDI, and per capita income. Procurement of confectionery
and soft drinks was positively associated with HDI and per capita income. Exploratory factor analysis grouped the independent
variables by reducing highly correlated variables into two uncorrelated component variables that explained 86.1% of total variance.
The first component included income, HDI, water fluoridation, and procurement of confectionery, while the second included free
sugar and procurement of soft drinks. Multiple regression analysis showed that caries is associated with the first component. Caries
experience was associated with better socioeconomic indicators of a city and exposure to fluoridated water, which may affect the
impact of sugars on the disease.
