title: Determinants for dental visit behavior among Hong Kong Chinese in a longitudinal study.
abstract: OBJECTIVE
  The aim of this research was to study the major determinants for dental services utilization among middle-aged Hong Kong Chinese in a longitudinal study using an expanded Andersen and Newman model as the theoretical framework.
  
  
  METHODS
  A random sample of 372 middle-aged Hong Kong Chinese were interviewed and clinically examined in an oral health survey. The findings were explained to the subjects and they were advised to seek care from their own dentist as appropriate.
  
  
  RESULTS
  A total of 322 subjects were interviewed over the telephone after 12 months. About half had visited a dentist within the study period. Results of the bivariate analysis showed that proportionally more subjects who had dental benefit coverage, had prevention-oriented attitudes, were regular users of dental services, had received counseling from a dentist, or had more filled teeth at the baseline examination had visited a dentist within the study period. Logistic regression analysis produced a final model consisting of seven factors and three interaction terms that was able to classify 68 percent of the subjects into the correct user category.
  
  
  CONCLUSIONS
  The expanded Andersen and Newman model was useful as a theoretical framework in studying the dental services utilization behaviors of the Hong Kong adults.
