Abstract:
Objective:To investigate the influential factors correlated to bone mineral density(BMD) in the lumbar vertebra of postmenopausal females,and to find out the influence of body mass and menostasis time on BMD. Methods: BMD in the frontal and lateral lumbar vertebrae of postmenopausal females were measured by dual-energy X-ray absorptiometry(DXA).The correlations of BMD to age,body height,body mass,body mass index(BMI),menopausal age,and/or menopausal years were analyzed using multiple linear regression with SPSS10.0. Results:The change of BMD in the frontal lumbar vertebra was positive to body mass but negatively with postmenopausal years,and that in the lateral lumbar vertebra was closely correlated to BMI. Conclusion: Bone mineral density decreases with increase of menostasis time.Females with a high body mass numerical value have higher bone mineral density.
