Bone-mass peak in multiparity and reduced risk of bone-fractures in menopause

摘要: Objectives: Pregnancy has been proposed as a risk factor for the development of osteoporosis; however, results are controversial. Women in Colombia multiparous, and therefore they represent an ideal population investigation effect parity on osteoporosis. Methods: The study included 1855 post-menopausal Hispanic women from Barranquilla, who were referred to our osteoporosis clinic routine evaluation their bone mineral status. Bone density (BMD, g/cm2) was measured using dual energy X-ray absorptiometry. Total body, femoral lumbar areas scanned. Results: BMD total hip legs (P<0.0001), Ward's area (P<0.002) intertrochanteric (P<0.003) high with at least one delivery comparison nulliparous women. calcium body contents also after second delivery. A history fractures found 22.9% (n=425) relative bone-fractures (O.R. 0.41; P<0.000002) multiparous In addition, osteopenia 2.01; P=0.008) 3.99; P=0.0004) most often present Conclusions: Pregnancies this appear be protective against increase related number pregnancies, suggesting existence mass peak during pregnancy.
