Although weight-bearing exercise among previously sedentary adult females can increase bone mineral density (BMD), cross-sectional studies suggest that high-intensity exercise among amenorrheic athletes may be detrimental to bone health. The long-term effects of athletic participation on BMD should be examined. Objectives. This study was designed to: (1) Determine the prevalence of varsity athletic participation among female university graduates who participated in a mail survey; and, (2) Compare BMDs of high school varsity female athletes with women who were sedentary during the same time period, while controlling for covariates. Methods. A survey was mailed to 7291 alumnae of 2 Southern California universities in the classes of 1987-1991. The survey was returned by 1900 (26.1 %), and 1373 (72.3%) consented to further contact. Of the latter, 73 athletes (70.6% of those eligible) and 67 controls (53.1 % of those eligible), all 30-35 years of age, in a clinic evaluation, provided their health histories, anthropometric measurements, physical activity and dietary assessments, and dual energy x-ray absorptiometer measurements of the hip and spine. Results. Athletes were taller (p
