摘要
目的探讨老年男性人群骨转换标志物(BTMs)和性腺激素随增龄的变化趋势,以及性腺激素与BTMs的关系。方法收集年龄60至91岁、门诊常规查体人群337例进行单中心横断面研究。收集空腹血测定血清骨钙素(OC)、1型胶原交联C-末端肽(CTX)、1型原胶原N-端前肽(P1NP)、25-羟维生素D(25OHD)、甲状旁腺激素(PTH)、总睾酮(TT)、雌二醇(TE2)、性激素结合球蛋白(SHBG)、卵泡刺激素(FSH)、黄体生成素(LH)及血钙磷;用Vermeulen公式计算游离睾酮(FT)。按每5岁1个年龄段分组,用一般线性模型方差分析比较各年龄组间骨转换标志物及各性腺指标的差异。用多元线性回归分析与骨转换标志物相关的因素。P<0.05表示差异有统计学意义。结果随年龄增长,OC、CTX和P1NP均呈下降趋势,FSH、LH、SHBG呈升高趋势,校正年龄、肝肾功能、体重指数、血钙磷、PTH、Vit D后,性腺指标中仅SHBG与各BTMs明显相关。结论年龄是BTMs的影响因素,SHBG是BTMs的独立影响因子,其通过直接或间接方式影响骨代谢。
