摘　　要：目的了解哈尔滨市城区初中生维生素D(Vit D)缺乏的流行现状,并探究其影响因素,为本地区青少年Vit D缺乏的干预提供理论依据。方法抽取哈尔滨市城区某中学6~8年级的所有学生,对其进行血清Vit D指标含量的测定及自拟问卷调查。结果本次共调查565名初中生,血清25-(OH)D平均水平为(15.25±6.98)ng/ml,Vit D严重缺乏率、缺乏率、不足率以及充足率分别为19.47%、62.12%、16.28%和2.12%。人口学特征分析显示,女生、年龄较低以及父母受教育程度较低的学生,其血清25-(OH)D水平相对较低,而Vit D缺乏率相对较高,差异均具有统计学意义(P<0.05)。Vit D的来源情况分析显示,25.31%的学生每天补充Vit D制剂,但其中只有18.18%的学生补充量超过600 U/d;36.46%的学生每日饮奶量超过250 ml;74.87%的学生每日户外活动时间超过30 min。经常饮奶、饮奶量较多以及每日户外活动时间较长的学生血清25-(OH)D水平较高,差异具有统计学意义(P<0.05)。多元线性回归分析显示,男性、年龄越大、父母受教育程度越高、每日户外活动时间越长的学生血清25-(OH)D水平越高。结论哈尔滨城区青少年Vit D缺乏状况较为严重,影响因素较多。亟需及早采取有效措施,以改善本地区Vit D缺乏的流行现状。Objective To describe the prevalence of vitamin D （Vit D） deficiency in adolescents in Harbin city,and to analyze the influencing factors, in order to provide theoretical basis for Vit D deficiency intervention in adolescents from local area. Methods The level of serum Vit D was measured and questionnaires were filled out by students of grade 6-8 in a middle school of Harbin City. Results A total of 565 middle school students were enrolled in this study. The level of ser- um 25- （OH） D was （ 15.25 ± 6.98） ng/ml, the prevalence of Vit D severe deficiency, deficiency, insufficiency and sufficiency were 19.47% ,62. 12%, 16. 28% and 2. 12% respectively. Demographic characteristics analysis showed that students who were girls or lower age,or lower parents education level had lower serum 25 （OH）D levels and higher Vit D deficiency prev- alence,and the differences were statistically significant （P〈0.05）. Analysis of the source of Vit D showed that 25.31% of students had daily extra Vit D supplements,but only 18.18% took more than 600 U/d; 36.46% of students had daily milk drinking more than 250 ml; 74. 87% of students did daily outdoor activities more than 30 minutes. Students with frequent milk drinking,more milk intake and longer daily time activities outdoors had higher serum 25-（OH）D level, and the differ-ence was statistically significant （P〈0. 05）. Multiple linear regression analysis showed that male students, elder age students,students with higher education level of parents and longer daily time activity outdoors had higher serum 25 （OH） D level. Conclusions The status of Vit D deficiency in adolescents in Harbin city is serious,and the influencing factors are complex. It is urgent to take effective measures to improve the regional epidemic status of Vit D deficiency.
