Abstract
Brot C, Jensen LB, Smensen OH (Copenhagen Municipal Hospital, Copenhagen, Denmark). Bone mass and risk factors for bone loss in perimenopausal Danish women Objectives: To determine risk factors for low bone mass at menopause and risk factors for subsequent bone loss in the following period. Design: A cross-sectional study and a 2-year prospective follow-up. Setting: The catchment area of Sundby Hospital in Copenhagen. Subjects: Four hundred and thirty-three women aged 45–58 years, with amenorrhea for 3–24 months, of whom 87 were followed for a 2-year period. Measurements: Registration of life-style and anthropometric variables, reproductive history, and family history of fractures. Total body bone mineral content (BMC) was measured with dual energy X-ray absorptiometry. Results: By means of multiple regression analysis height, body weight, and length of reproductive period were found to be positively related to whole body BMC (P < 0.001), whilst a negative relationship was found to age (P < 0.001), smoking (P < 0.001), and family history of fractures (P < 0.005). In the longitudinal study, only body weight at the inclusion (P = 0.005) and subsequent changes in body weight and fat mass (P < 0.001) were related to the changes in bone mass. Conclusion: The most significant predictors for bone loss were changes in body weight and fat mass. Hence, weight loss is a risk factor for bone loss in the early postmenopausal period, whereas weight gain seems to preserve bone.Keywords
