摘要
目的探讨综合营养措施对预防和改善中老年妇女骨密度的作用。方法以185名骨密度水平较低的中老年妇女为研究对象,根据年龄、骨密度水平等因素均衡后随机分为3组。干预A组每天补充钙、维生素D3和大豆异黄酮,同时进行营养宣传教育;干预B组和对照组使用安慰剂,干预B组同时进行营养宣传教育,对照组不进行营养宣传教育。通过比较干预前后骨密度变化情况,评价其效果。结果干预A组对象腰椎（L2~4）侧位的骨密度平均值整体均数上升3.53%,由干预前的（0.5317±0.0831）上升至干预后的（0.5505±0.0949）;干预B组上升1.71%,由干预前的（0.5307±0.0946）上升至干预后的（0.5398±0.0939）;对照组下降4.75%,由（0.5297±0.0858）下降至（0.5046±0.0806）;干预组与对照组骨密度变化比较,差异有统计学意义（P〈0.05）。结论采取适量补充钙、维生素D3及大豆异黄酮和（或）营养宣传教育等综合营养干预措施,对预防和改善中老年妇女骨质疏松具有显著作用。
Objective To investigate the effects of the comprehensive nutritional intervention and education on nutrition - related knowledge. Methods Bone density of 185 middle aged and aged women volunteers＇ side vertebrae （I4-4） was detected by using dual energy x - ray absorptionmetry. The subjects were divided into 3 groups randomly according to subjects＇ age and the levels of bone density. Group A was supplemented with daily 500 mg calcium, 200 IU vitamin D3,90 mg soybean isoflavones, and was educated with nutrition - related knowledge. Group B was taught with nutrition - related knowledge while the control group did not. Results The average of bone density of the side vertebrae（14-4）in group A increased by 3.35 % while group B rose by 1.71%. However, the control group decreased by 4.75 % . The variation of bone density between experimental group and control group has a significant difference（ P 〈 0.05 ）. Conclusion The comprehensive nutritional intervention and nutrition - related knowledge have significant effects on preventing and improving the conditions of osteoporosis in middle aged and aged women.
