Factors related to utilization of dental services by the elderly

A household interview survey of 883 persons aged 62 and older residing in Seattle, Washington, asked about a broad range of health care and social service issues, including the need for and use of dental care. The Anderson model of health services utilization was used to identify predisposing, enabling, and need characteristics hypothesized to affect the use of dental services. A path analysis was conducted to distinguish the direct and indirect effects of the variables. The results showed that none of the predisposing variables, including age, was a significant factor in explaining the use of dental services. Education had both direct and indirect positive relationships to use. Having a regular sources of dental care was also an important factor affecting utilization. Neither income nor insurance variables were powerful factors. Need, measured by an index of dental problems and having dentures, was the stronger determinant of dental care use. In general, the model was better at predicting whether or not dental care would be sought by an older person at all (R2 = .27) than in predicting the amount of service used (R2 = .06).
