目的 :探讨成年女性体力活动水平与骨矿含量和反映骨代谢有关生化指标的关系。方法 :以江门市 2 2 0位健康成年女性作为研究对象 ,采用MOSPA体力活动问卷评价其体力活动水平 ,并测量骨矿含量以及血清钙、磷、碱性磷酸酶、酸性磷酸酶、非前列腺酸性磷酸酶及尿钙和尿肌酐比值等反映骨代谢的生化指标的水平。结果 :校正有关混杂因素后 ,与低体力活动组相比 ,高体力活动组女性骨矿含量和骨皮质系数增加 ,血清碱性磷酸酶含量增加 ,酸性磷酸酶和非前列腺酸性磷酸酶含量下降。结论 :与低体力活动组比较 ,高体力活动组女性骨矿含量增加 ,骨形成较活跃 ,而骨吸收减少。
Objective: To explore the relationship between the physical activity level of adult women and bone mineral content and the biochemical indexes reflecting bone metabolism. Methods: A total of 220 healthy adult women in Jiangmen City were enrolled in this study. Physical activity questionnaire of MOSPA was used to evaluate their physical activity, bone mineral density, serum calcium, phosphorus, alkaline phosphatase, acid phosphatase, non-prostatic acidity Phosphatase and urinary calcium and urinary creatinine ratio reflects the biochemical indicators of bone metabolism levels. RESULTS: After adjusting for confounding factors, bone mineral content and cortical bone coefficient were increased in women with high physical activity compared with low physical activity group, serum alkaline phosphatase level increased, and acid phosphatase and non-prostatic acid phosphatase levels decreased. Conclusion: Compared with the low physical activity group, the bone mineral content increased, the bone formation was more active and the bone resorption decreased in the high physical activity group.
