Bone, Endocrine and Lifestyle Longitudinal Study
- Conditions
- Osteoporosis
- Registration Number
- NCT02063074
- Lead Sponsor
- University of Southern California
- Brief Summary
The purpose of this proposal is to determine the long-terms effects of hormone and lifestyle factors on bone health in young women over a 20-year time period. It is our primary hypothesis that premenopausal women with irregular periods or endocrine issues related to estrogen will have significantly poorer low back and hip bone health when compared to regularly menstruating women. It is our secondary hypothesis that long-term assessment of changes in endocrine function and lifestyle behaviors will assist in establishing risk factors for osteoporosis in young women. This study will include 1000 premenopausal women. The women will participate in the collection of a blood sample, bone scan, body fat measures, and lifestyle questionnaires. In addition, we hope to use this initial study to develop a group of women to follow throughout menopause, with additional visits occurring every 5 years over the course of their life.
