Hip fractures were more common amon non-Hispanic white woman (139 par 1oO,ooO,95% co&demx interval (CI) = l-153) than amon Mcxiuan-American (67 par 100,ooO; 95% Cl = 51-82) or black (55 per 100,ooO; 95% Cl = 27-83) women. Thus, Mexican Amaians and blacks are relatively pro&&xl from hip fractures, and they may benefit less than whites from prophylactic Wrapias for ostarporosis.
