【摘要】：目的了解高校学生维生素D水平及相关因素,为干预青少年维生素D缺乏提供科学依据。方法于2015年4月在阜阳市某高校方便抽取大一到大三年级6个班级的339名青少年进行维生素D相关因素问卷调查,并采集指尖血应用串联质谱法检测25(OH)D水平。结果研究对象的25(OH)D水平范围为(6.2~34.5)nmol/L,均值为(16.0±5.4)nmol/L。单因素分析显示,年龄较小、女性、非独生子女、经常晒太阳、近1周每天11:00—14:59户外活动时间≥30min的青少年有较高的25(OH)D水平。食用含维生素D相对较多食物的频率与25(OH)D水平间无统计学意义关联。多因素分析显示,年龄越大,25(OH)D水平越低(β=-0.62,95%CI=-1.04~-0.20);女生25(OH)D水平较男生更高(β=2.31,95%CI=0.96~3.66);晒太阳频率越高(β=0.99,95%CI=0.13~1.85)和11:00—12:59户外活动时间越长(β=0.93,95%CI=0.27~1.58),25(OH)D水平越高。结论青少年维生素D缺乏十分普遍,食用含维生素D相对高的食物不能有效提高25(OH)D水平,而经常晒太阳和增加有效户外活动时间可有效提高维生素D水平。
[Abstract]:Objective to investigate the level of vitamin D and its related factors in college students, and to provide scientific basis for intervention of vitamin D deficiency in adolescents.Methods in April 2015, 339 adolescents in 6 classes from freshmen to sophomores in Fuyang City were selected conveniently to investigate the related factors of vitamin D, and fingertip blood was collected to detect the 25(OH)D level by tandem mass spectrometry.Results the 25(OH)D level ranged from 6.2nmol / L to 34.5nmol / L, with an average of 16.0 卤5.4nmol / L.Univariate analysis showed that adolescents who were younger, female, non-only child, often basked in the sun, and had higher 25(OH)D levels at 11: 00-14: 59 / day for nearly one week.There was no significant correlation between the frequency of consuming vitamin D and the level of 25(OH)D.Conclusion Vitamin D deficiency in adolescents is very common. Consuming foods with relatively high vitamin D content can not effectively improve the level of 25(OH)D, while regular sun exposure and effective outdoor activities can effectively increase vitamin D levels.
