老年男性血清维生素D水平状况及其与甲状旁腺激素的相关性研究
目的:探讨老年男性血清维生素D水平及其与甲状旁腺素及骨代谢指标的相关性。方法收集2010年9月至2013年9月在上海瑞金医院老年病科病房住院及门诊患者895例,平均年龄为76岁。测定其血清25-羟基维生素D[25(OH)D]、血钙(Ca)、血磷(P)、甲状旁腺激素(PTH),I型胶原分子N-端前肽(PINP)及β-I型胶原C端肽(β-CTX)水平。根据血清25(OH)D水平将患者分为维生素D严重缺乏组(<25 nmol/L)、维生素D缺乏组(25~50 nmol/L)、维生素D不足组(50~75 nmol/L)和维生素D充足组(>75 nmol/L)。结果(1)895例老年男性患者年龄60~9...

Summary: | 目的:探讨老年男性血清维生素D水平及其与甲状旁腺素及骨代谢指标的相关性。方法收集2010年9月至2013年9月在上海瑞金医院老年病科病房住院及门诊患者895例,平均年龄为76岁。测定其血清25-羟基维生素D[25(OH)D]、血钙(Ca)、血磷(P)、甲状旁腺激素(PTH),I型胶原分子N-端前肽(PINP)及β-I型胶原C端肽(β-CTX)水平。根据血清25(OH)D水平将患者分为维生素D严重缺乏组(<25 nmol/L)、维生素D缺乏组(25~50 nmol/L)、维生素D不足组(50~75 nmol/L)和维生素D充足组(>75 nmol/L)。结果(1)895例老年男性患者年龄60~99岁,平均年龄76岁。血清25(OH)D平均值为(43.52±21.97)nmol/L。维生素D缺乏者(≤50nmol/L)为592人(67%),维生素D不足者(50~75 nmol/L)为223人(25%)。维生素D缺乏或不足者高达92%,维生素D充足者(>75 nmol/L)仅为80人(8%)。(2)不同年龄段血清25-(OH)D的比较显示,血清25-(OH)D水平随增龄而逐渐降低。60~69岁组25-(OH)D值最高,为(46.27±20.76)nmol/L,与其它各组比较差异均有统计学意义(P<0.05)。相关分析表明,血清25-(OH)D与年龄呈负相关(相关系数r=-0.088,P=0.008)。(3)甲状旁腺素(PTH)的平均水平为(55.74±29.06)pg/ml。相关分析显示,25-(OH)D与PTH、PINP、β-CTX均呈负相关(r值分别为-0.209、-0.109、-0.122,P均<0.05)。血25-(OH)D与Ca呈正相关(r=0.206,P<0.001)。血25-(OH) D与BMI、P均无相关性( P均>0.05)。结论老年男性存在严重的维生素D缺乏或不足。血25-( OH ) D与PTH、年龄、PINP、β-CTX均呈负相关。 |
