老年男性晒太阳与其血清25-羟基维生素D的相关性

目的：了解老年男性维生素D的缺乏情况，以及血清25-羟基维生素D[25（OH）D]与晒太阳的相关性。方法对350例老年男性进行晒太阳情况的调查，并检测其血清25（OH）D水平，然后分析两者之间的关系。结果老年男性25（OH）D缺乏率高达58%。在350例老年男性中，晒太阳239（68%）例，其25（OH）D为（19.27＆#177;8.56）ng/ml，不晒太阳111（32%）例，其25（OH）D为（17.15＆#177;8.50）ng/ml，两者在25（OH）D上差异有统计学意义（P〈0.05）。结论老年男性维生素D缺乏十分普遍，而晒太阳是提高老年男性血清25（OH）D的重要手段。

Objective To evaluate the status of vitamin D deficiency in men aged 60 and over,and to investigate the association between serum 25-hydroxyvitamin D[25（OH）D）]and basking. Methods A cross-sectional survey was conducted in a cohort comprising 350 men aged 60 and over. All participants underwent a questionnaire survey for basking. Serum 25（OH）D measurement was conducted,and the association between serum 25（OH）D and basking was analyzed. Results Vitamin D deficiency 25（OH）D〈20ng/ml were found in 58%men aged 60 and over. The level of serum 25（OH）D was significantly higher in elderly men who frequently basked than who didn＇t（19.27±8.56）ng/ml vs （17.15±8.50）ng/ml;P〈0.05）. Conclusions Vitamin D deficiency is prevalent in men aged 60 and over. Basking can be an effective way to increase the level of serum 25-hydroxyvitamin D.
