Perceived risks and reported behaviors associated with osteoporosis and its treatment.

This study investigates older American women's knowledge and risk perceptions about osteoporosis and its treatment. Our results indicate that older U.S. women undervalue the health impact of osteoporosis; they consider it controllable, and neither life threatening nor dreaded relative to other possible diseases or conditions. At least 1/3 of older women in a diagnosed and general sample also confused osteoporosis with arthritis. Women scored highest on osteoporosis knowledge questions related to items under their personal control, such as diet or exercise. Further, women who understood the effects of a particular behavior on osteoporosis were more likely to act in accordance with that knowledge than were women who did not understand those effects.
