Treatment of low bone mass in premenopausal women: when may it be appropriate?
The diagnosis and treatment of osteoporosis in postmenopausal women has been well defined. Criteria for making a diagnosis using bone density testing has been established and widely disseminated. However, the definition established by the World Health Organization for osteoporosis cannot be used for other populations such as premenopausal women without further study. Measuring bone mass in premenopausal women should be done infrequently and only if specific and significant risk factors are present. Premenopausal women have a low risk for fracturing but women with low bone mass are at a greater risk for developing fractures before and after menopause. The major reason for low bone mass is the failure to reach peak bone mass because of genetic influences, although some environ-mental factors may also play a role. Hormonal therapy for hypogonadism, treatment of diseases such as hyperpara-thyroidism, and keeping medications with detrimental effects on bone to a minimum are important components of treatment. Pharmacologic treatment of low bone mass in premenopausal women has not been well studied although on rare occasions it may be appropriate in women with low bone mass, defined as a Z score of -2 or less, and the presence of other diseases or risk factors. Caution is urged because of the unknown effects of treatment in this population. Further study of the implications of low bone mass and the effects of treatment in this group of women is needed.
