Abstract

Purpose：The purpose of the study was to determine factors affecting bone mineral density among premenopausal women aged over 45 years old and make a contribution to preventing osteoporosis among postmenopausal women. Materials and Methods：A total of 133 women enrolled in the study and completed a self-administered questionnaire that measured results of bone mineral density exam and biochemical exam, demographic characteristics, smoking and drinking, physical activities and reproductive characteristics.
Results
：The results of the study are summarized as follows: Of total subjects, 20.2% showed a reduction on bone mineral density. Age was the most important factor predicting bone mineral density level. A frequent intake of meat rather than vegetables had a significant impact on bone mineral density. Women with a menstruation cycle shorter than 28 days showed significantly high bone mineral density. Multiple regression analysis revealed a correlation between age and risk of osteoporosis. The explainability for variables was 16%.
Conclusion
：It is necessary to develop programs designed to help women in their 30s to maintain the maximum bone density and prevent osteoporosis after menopause.
