【摘要】：目的分析中老年体检者血清25-羟维生素D[25(OH)D]水平,了解维生素D营养状况。方法宁夏银川地区的中老年体检者931例采用电化学发光法测定血清25(OH)D水平,统计分析各年龄组和1年的25(OH)D分布状况。结果 25(OH)D平均水平为(14.57±8.20)ng/ml,维生素D缺乏和不足者占81.03%,其中男性占78.42%,女性占82.95%,性别差异无统计学意义(t=0.71,P0.05)。根据血清25(OH)D的水平分为营养缺乏症,不足组,正常组和良好组,各组所占比例分别为42.32%,38.67%,14.50%和4.51%。各年龄段维生素D营养状况分布不同,进一步直线相关分析提示25(OH)D水平与年龄呈负相关(r=-0.15,P0.01)。25(OH)D水平呈现季节性变化(F=7.21,P0.01),夏秋季25(OH)D水平较高,而冬春季相对较低。结论宁夏银川地区中老年人群普遍缺乏血清维生素D,冬节较为严重,且随着年龄的增大有下降的趋势。提示应关注中老年人维生素D营养状况,及时补充维生素D。
[Abstract]:Objective to analyze the elderly subjects serum 25- hydroxyvitamin D[25 (OH) D] level, to understand the nutritional status of vitamin D in Yinchuan area of Ningxia. Methods 931 cases of elderly volunteers by electrochemiluminescence assay of serum 25 (OH) D levels, statistical analysis of each age group and 1 years in 25 (OH) D distribution. Results 25 (OH) D average (14.57 + 8.20) ng/ml, vitamin D insufficiency and deficiency accounted for 81.03%, which accounted for 78.42% of men, women accounted for 82.95%, there was no significant gender differences (t=0.71, P0.05). According to the serum 25 (OH) D levels were divided into nutritional deficiency, lack of normal group. Group and good group, each group accounted for 42.32%, 38.67%, 14.50% and 4.51%. the age distribution of different vitamin D nutritional status, further linear correlation analysis showed that 25 (OH) level of D was negatively correlated with age (r=-0.15, P0.01).25 (OH) D levels showed seasonal changes (F=7.21, P0.01) summer and autumn 25. (OH) D levels were higher in spring and winter is relatively low. Conclusion the Ningxia Yinchuan area in the elderly general lack of serum vitamin D, winter is more serious, and with the increase of age decreased. That should be concerned about the elderly and the nutritional status of vitamin D and vitamin D. supplement
