目的研究不同性别人群血清白蛋白水平,血清钙、镁、磷浓度,以及血红蛋白浓度与腰椎、股骨颈两部位骨密度的相关性。方法回顾性分析117例不同性别人群,每人检测腰、髋两部位双能x线骨密度值,以及血常规、血生化(包括血清白蛋白、前白蛋白、血钙、血镁、血磷)。将所有人分为女性组和男性组,每组按10岁为一个年龄段,分为5组,分别为≤40岁,41-50岁,51-60岁,61-70岁,≥71岁,分别进行各变量与骨密度的相关性研究和回归分析,并作对比研究。结果女性组中血清白蛋白和股骨颈骨密度明显相关(r=0.542,P0.05)。结论血清白蛋白、血红蛋白与腰椎和股骨颈骨密度具有相关性,白蛋白、血红蛋白的降低可能是骨密度下降的依赖年龄的危险因素。在骨质疏松症的防治中,升高血清白蛋白、纠正贫血需要重视。
