Indicators of oral health in diverse ethnic and age groups: findings from the International Collaborative Study of Oral Health Outcomes (ICS-II) USA research locations.

Racial-ethnic group differences are assessed using a standardized set of oral health indicators, as well as various predisposing, enabling and need characteristics collected in the International Collaborative Study of Oral Health Outcomes (ICS-II) USA research locations. The unique data set contains comparable data on African-American, Native American, Hispanic, primarily Mexican-American, and White adults. Age group differences in oral health indicators are also compared in two adult age cohorts (35-44 and 65-74 years). Since data were collected from geographically diverse regions of the United States, differences in oral health indicators are considered within the context of different dental care delivery systems and external environments. Results indicate that the gap in oral health between Whites and ethnic minority groups is pervasive across research locations and age cohorts. Variation in regional dental care delivery systems and the varying effects of race-ethnicity and age cohort suggest that alternative health promotion strategies will be needed for improving oral health in diverse populations.
