FINDINGS: UCLA researchers and colleagues analyzed data for 2,213 women between the ages of 42 and 52 who participated in the bone sub-study of the Study of Women's Health Across the Nation to determine whether women with vasomotor symptoms (VMS) -- which include hot flashes and night sweats -- had lower bone mineral density.
The researchers found that postmenopausal women with VMS had lower lumbar and total hip bone mineral density than those without VMS. Premenopausal women and early perimenopausal women who had VMS were found to have lower femoral neck bone mineral density than those without VMS.
