小榄社区老年人血清25(OH)VitD水平的调查研究

目的 调查小榄镇体检老年人血清25(OH)VitD的水平,探讨老年人维生素D缺乏情况及年龄、性别与血清25(OH)VitD的相关性.方法 选择2015年1月至2016年1月期间小榄镇体检老年人2041例为研究对象,检测血清25(OH)VitD浓度,并进行统计学分析.结果 本组2041例老年人中,1661例存在维生素D缺乏或不足的状况,其发生率为81.38%;老年女性25(OH)VitD充足者为11.31%,明显低于老年男性的33.28%,差异有统计学意义(P<0.05);血清25(OH)VitD在60~69岁、70~79岁及>80岁三个年龄阶段,老年男性及女性的血清25(OH)VitD水平均依次下降,差异均有统计学意义(P<0.05);血清25(OH)VitD在60~69岁、70~79岁及>80岁三个年龄阶段,老年女性均明显低于老年男性,差异均有统计学意义(P<0.05).结论 小榄地区老年人普遍存在维生素D缺乏,且维生素D缺乏随着年龄的增加而逐渐加重,老年女性维生素D缺乏更加明显.

Investigation of serum 25(OH)VitD concentration in elderly people of Xiaolan Community

Objective To investigate serum 25(OH)VitD concentration and the lack of vitamin D in elderly peo-ple of Xiaolan Community, and to explore correlation of serum 25(OH)VitD with age, gender. Methods A total of 2041 cases of elderly people in Xiaolan Community from January 2015 to January 2016 were studied, and serum 25(OH)VitD concentration were detected. Statistical analysis was performed. Results Among the 2041 elderly people, 1661 (81.38%) had vitamin D deficiency or insufficiency. The proportion of elderly women sufficient with 25(OH)VitD was 11.31%, which was significantly lower than that of elderly men (33.28%), P<0.05. The serum 25(OH)VitD concentration in elderly men and women were all declined in age of 60~69 years, 70~79 years and>80 years, and the differences were statistically significant (P<0.05). In the three age stages, the serum 25(OH)VitD levels in elderly women were significantly lower than those in elderly men, and the differences were statistically significant (P<0.05).
