This study examined racial and ethnic differences in use of health services
by white, African American, and Hispanic elderly people. Using a national
representative sample of elderly from the AHEAD study, we estimated a two-p
art model of health services utilization. We found that African American an
d Hispanic elderly were more likely to make physician visits than white eld
erly. Among those who made physician visits, Hispanic elderly made more vis
its than white elderly. We also found that the effects of factors affecting
use of health services varied by race and ethnicity. These results lead us
to reject the homogeneity assumption made by many health services research
ers.
