目的:调查高龄男性血清25-羟基维生素D[25(OH)D]的正常情况,分析补充维生素D与血清25(OH)D的关系。方法:对374例高龄男性维生素D补充情况进行调查,并检测其血清25(OH)D,分析两者间的关系。结果:374例高龄男性中,血清25(OH)D水平正常率仅为10%,其中88例(24%)补充维生素D,其血清25(OH)D水平为(20.82±9.27)ng·ml~(-1),286例(76%)未补充维生素D,其25(OH)D水平为(18.27±8.49)ng·ml~(-1),差异有统计学意义(P<0.05)。结论:高龄男性血清维生素D正常率较低,而补充维生素D可能是提高高龄男性25(OH)D水平的重要方法。
OBJECTIVE: To investigate the serum levels of 25-hydroxyvitamin D [25 (OH) D] in elderly men and to analyze the relationship between vitamin D supplementation and serum 25 (OH) D. Methods: To investigate the supplement of vitamin D in 374 elderly men and to detect the serum 25 (OH) D, and analyze the relationship between them. Results: Of 374 elderly men, the normal serum 25 (OH) D level was only 10%. 88 (24%) were vitamin D supplemented and the serum 25 (OH) D level was (20.82 ± 9.27) ng · ml The serum levels of 25 (OH) D were (18.27 ± 8.49) ng · ml -1 in 286 patients (76%) without vitamin D supplementation. The difference was statistically significant (P <0.05). CONCLUSION: The normal serum vitamin D in older men is lower, and vitamin D supplementation may be an important way to improve the 25 (OH) D level in older men.
