Abstract

Objective: To ascertain and compare the oral health status and related sociodemographic risk indicators in children in Los Angeles (LA) County with children in the United States.

Methods: Data from the National Health and Nutrition Examination Survey (NHANES) 1999-2004 were used to calculate prevalence estimates for children aged 2-13 years living in LA County and in the United States. Sociodemographic indicators were evaluated using multiple logistic regression modeling.

Results: Overall, children in LA County were more likely to experience dental caries than children in the United States in 1999-2004. In the primary dentition, nearly 40% of preschool children residing in LA County had dental caries compared to 28% of same-age children in the United States. Among children aged 6-13, 44% living in LA County had dental caries in the permanent dentition compared to 27% in the United States. Mexican American children in LA County had higher caries experience in permanent teeth (but not in primary teeth) than US Mexican American children. Among children aged 6-9 years, there was no difference in the prevalence of dental sealants in permanent teeth between those living in LA County and in the United States. However, among children aged 10-13 years, dental sealants were more than twice as prevalent in US children (40.8%) than in LA County children (17.5%). Among LA County children, the adjusted odds of having caries experience or untreated dental caries in permanent teeth were not higher among children from lower income families than in lower income children in the United States.

Conclusions: Children residing in LA County had less favorable oral health than children in the United States in 1999-2004. The usual sociodemographic caries risk indicators identified among children in the United States were not consistently observed among children in LA County. Unlike in the wider United States, poverty was not a risk indicator for dental caries in older children in LA County.
