摘要
目的探讨北京市城区老年妇女维生素D营养状况与体成分的关系。方法随机抽取北京市60岁以上老年绝经妇女400名,年龄中位数为67.8岁。放射免疫法测定血清25-羟维生素D[25(OH)D]浓度,双能X线吸收法(DEXA)测定全身体成分。结果血清25(OH)D平均为(14.4±5.7)ng/ml,维生素D与全身、髋部及双下肢的体脂百分比(PBF)显著负相关(r=-0.17～-0.10,P<0.05)。维生素D缺乏和不足者全身、髋部和下肢的PBF高于维生素D适宜者;其中,全身PBF分别高7.4%和3.7%(P<0.05)。结论北京城区老年妇女血清维生素D水平较低,而维生素D水平较低者的体脂和PBF水平较高。
Objective To assess the association between vitamin D status and body composition of urban elderly women in Beijing. Methods Total 400 community-dwelling women aged above 60 yrs （the median age 67.8 yrs） were selected randomly in Beijing, China. Their serum 25-hydroxyvitamin D [25（OH）D] concentrations were measured at late spring by radioimmunoassay, body composition of total body and different regions of body was measured by dual-energy X-ray absorptiometry （DEXA）. Results The average serum 25（OH）D concentration was （14.4±5.7） ng/ml. Serum 25（OH）D level was negatively associated with percentage of body fat （PBF） at total body, pelvis and legs （r=-0.17--0.10, P〈0.05）. Subjects with vitamin D deficient or inadequate had significantly higher PBF at total body, pelvis and right leg than subjects with 25 （OH）D adequate （25 （OH）D ≥20ng/mL）, for instance, higher by 7.4% and 3.7% at total body, respectively. Conclusion Vitamin D status of urban elder women in Beijing was insufficient. Subjects with vitamin D inadequate had more BF and PBF.
