【摘要】 目的 调查昆山地区医院门诊及住院患者维生素D缺乏的患病率，并探讨其相关危险因素。方法 将28 194例昆山市中医医院门诊及住院患者作为研究对象，其中男9 259例，女18 935例，对患者资料进行回顾性研究。结果 28 194例患者血清25羟维生素D水平为18(12,23)ng/mL,维生素D缺乏患病率为59.15%。二元logistic回归分析结果显示，住院[比值比(OR)=2.210,95%置信区间(95%CI):2.082～2.345,P<0.001]、冬季(OR=1.598,95%CI:1.481～1.724,P<0.001),女性(OR=2.042,95%CI:1.932～2.158,P<0.001)、低龄(OR=2.439,95%CI:2.104～2.829,P<0.001)是发生维生素D缺乏的危险因素。结论 昆山地区医院门诊及住院患者维生素D缺乏比较普遍，尤其在冬春季住院的低年龄段女性患者，应进行维生素D缺乏的筛查。更多还原

【Abstract】 Objective To investigate the prevalence of vitamin D deficiency among outpatients and inpatients in hospitals in the Kunshan area, and explore the related risk factors.Methods A total of 28 194 outpatients and inpatients were selected as the research subjects at Kunshan Hospital of Traditional Chinese Medicine.The sample included 9 259 males and 18 935 females.The patients’ data was retrospectively studied.Results The serum 25-hydroxyvitamin D level of 28 194 patients was 18(12,23) ng/mL,and the prevalence of vitamin D deficiency was 59.15%.Binary logistic regression analysis showed that hospitalization(OR=2.210,95%CI:2.082-2.345,P<0.001),winter(OR=1.598,95%CI:1.481-1.724,P<0.001),female(OR=2.042,95%CI:1.932-2.158,P<0.001),and young age(OR=2.439,95%CI:2.104-2.829,P<0.001) were risk factors for vitamin D deficiency.Conclusion Vitamin D deficiency is prevalent among both outpatients and inpatients in hospitals in the Kunshan area, particularly among younger female patients who are hospitalized during the winter and spring seasons.Therefore, it is recommended that these patients be screened for vitamin D deficiency.更多还原
