A total of 1610 women completed a questionnaire that evaluated their risk factors for osteoporosis. A dual-energy x-ray absorptiometry scan followed. Analysis of data was performed by the 2-tailed chi(2) test and multivariate logistic regression. Age was directly related to osteoporosis, whereas weight was inversely related. Also, the lack of use of any estrogen was significantly related to the presence of osteoporosis.
