LOS ANGELES (AP) _ Debbie Reynolds has a new cause: osteoporosis.

The 67-year-old actress was diagnosed this year with the bone-thinning disease that caused her grandmother to become stooped and weakened.

``I don't want the same thing to happen to me. Nowadays, with all we know about detecting and preventing osteoporosis, there's little reason I, or any other woman, should not take steps to blunt the impact of bone loss,'' she said.

Miss Reynolds has joined a campaign to urge older women to get a bone-mineral density test to diagnose osteoporosis.

She said she is happy she took the test.

``Otherwise, I would be finding out by falling on the floor with a bone collapse,'' she said.
