目的:调查绝经前后妇女的体成分与绝经年龄、身高及应用维生素D和钙剂后骨密度的关系。方法:采用1∶1配对设计方法,将196例妇女分为绝经期前未用维生素D和钙剂者和用维生素D和钙剂者两组,采用米尺和磅秤测量两组妇女的身高和体重,采用双能X线骨密度仪检测两组妇女的骨质疏松值,采用超声骨密度仪检测两组妇女的左侧跟骨的超声速度、骨硬度指数和低骨量。观察两族妇女体内骨密度指标。结果:绝经前后不同年龄组妇女体质指数、超声速度、骨硬度指数、低骨量及骨质疏松值比较差异有统计学意义(P<0.05)。应用维生素D和钙剂的妇女骨密度较未应用维生素D和钙剂的妇女同年龄组相比,骨质疏松值有所下降。结论:绝经前后妇女合理应用维生素D和钙剂安全、有效,可早期预防骨质疏松,值得推荐,特别适用于绝经后妇女。
OBJECTIVE: To investigate the relationship between body composition and menopause age, height, and post-menopausal vitamin D and calcium post-menopausal women’s body composition. Methods: A one-to-one paired design method was used to divide 196 women into two groups without vitamin D and calcium before menopause and with vitamin D and calcium. The height and Body weight was measured by dual energy X-ray absorptiometry. Osteoporosis was measured in both groups. Ultrasonic bone densitometry was used to detect the left calcaneus ultrasonic velocity, bone stiffness index and low bone mass in both groups. Observe the bone mineral density index of two groups of women. Results: There were significant differences in body mass index, ultrasound velocity, bone stiffness index, low bone mass and osteoporosis between women of different ages before and after menopause (P <0.05). Women with vitamin D and calcium had lower bone mineral density than women without vitamin D and calcium in the same age group. Conclusion: Before and after menopause, the rational use of vitamin D and calcium in women is safe and effective, which can prevent osteoporosis at early stage. It is worth recommending, especially for postmenopausal women.
