目的：尽管维生素D缺乏症在全球成人中的发病率很高，但对青少年维生素D缺乏症的评估研究并不多。因此，本研究旨在评估伊朗沙赫鲁德学生维生素D缺乏症的患病率。方法：2011年冬季，对伊朗最大城市沙赫鲁德城乡的初中生和高中生进行了横断面描述性分析研究。本研究采用分层随机抽样与整群随机抽样相结合的方法。每个学生都完成了一份关于人口统计数据、社会经济状况、生活方式习惯(阳光照射、体育活动、乳制品消费)以及药物和个人病史的问卷。结果：共抽取4所初中和6所高中的1,047名学生作为研究对象。其中，男生占42.2%，女生占57.8%。研究人群维生素D水平的平均值和标准差为14.7+/-9.4 ng/mL。只有7.2%的男孩和3.8%的女孩有明显的阳光照射。每周饮用牛奶的中位数为3杯，范围为0~7杯。结论：伊朗青少年中维生素D缺乏症相当普遍，这主要是因为这一群体由于骨质疏松而过着不健康的生活方式。
Objective: Despite the high prevalence of vitamin D deficiency in adults worldwide, not many studies have evaluated the condition in adolescents. The present study was therefore conducted to assess the prevalence of vitamin D deficiency in a group of students from Shahroud, Iran.Methods: The cross-sectional descriptive analytical study was conducted on junior high and high school students of both genders from urban and rural areas of Shahroud, the largest city of Semnan Province in Iran, in winter 2011. The combination of stratified and cluster random sampling methods was applied in the study. A questionnaire on the demographic data, socioeconomic status, lifestyle habits (sun exposure, physical activity, dairy consumption), and drug and personal history was completed for each student. Blood samples were taken to assess vitamin D levels.Results: One thousand forty-seven students from four junior high and six high schools were recruited. From among them, 42.2% were boys and 57.8% were girls. Mean and standard deviation of vitamin D levels in the studied population were 14.7 +/- 9.4 ng/mL. Only 7.2% of the boys and 3.8% of the girls had sensible sun exposure. The median of milk consumption was 3 glasses per week, ranging from 0 to 7.Conclusion: It could be concluded that vitamin D deficiency is quite prevalent among the Iranian adolescents, and this is mainly because this group follows an unhealthy lifestyle due to osteoporosis.
