title: [Bone mineral density measurement in a perimenopausal period].
abstract: Women lose their lumber BMD by 20 to 50% for 10 years since menopause. Menopausal bone loss occurs when menstruation becomes irregular. Therefore, BMD measurement in a perimenopausal period can be a very important strategy for detection of women at serious risk for osteoporosis.
