摘要
目的探讨运动、体重指数及牛奶摄入对妇女骨代谢、骨密度影响。方法测定空腹血ALP、尿钙(Ca)、肌酐(Cr)和DEXA以测定腰椎、股骨上段骨密度。结果体重指数与血ALP、骨密度呈正相关,与Ca/Cr呈负相关,常年运动组骨吸收率较对照组低(P<0·05),骨密度较对照组高(P<0·05),常饮用牛奶组尿Ca/Cr和血ALP低于对照组(P<0·05),骨密度高于对照组(P<0·05)。结论体重越低,越容易发生骨质疏松,运动可维持骨量,摄入牛奶可延缓骨丢失,是防治骨质疏松的有效方法。
Objective To investigate the effect of physical activity, body mass index（BMI） and inttake of milk on bone metabolism and bone mineral density of women. Methods The empty blood ALP, urine Ca, Cr and the BMD in lumbar spine and proximal femur were determined by DEXA.Results BMI had a positive relation with blood ALP and BMD,negative with Ca/Cr. The group of continuing physical activity had a lower rate of resorption but higher BMD than control group （P〈0.05）. The group of continuing milk intake had lower bone resortption index, urine Ca/Cr, and bone formation index, boold ALP, higher BMD（P 〈 0.05） than the control group.Conclusion The lighter of weight, the easier of osteoporosis forms. Physical activity may maintain the bone mass,milk intake may delay the bone loss,so they are a useful method to prevent osteoprosis.
