目的探讨2型糖尿病患者血脂异常与血清维生素D水平的相关性。方法选取2021年2月—2023年2月在运城市盐湖区人民医院就诊的2型糖尿病患者396例为研究对象,根据血脂是否异常分为血脂异常组(n=173)和血脂正常组(n=223),收集患者的年龄、性...目的探讨2型糖尿病患者血脂异常与血清维生素D水平的相关性。方法选取2021年2月—2023年2月在运城市盐湖区人民医院就诊的2型糖尿病患者396例为研究对象,根据血脂是否异常分为血脂异常组(n=173)和血脂正常组(n=223),收集患者的年龄、性别、身体质量指数(body mass index,BMI)及血压等基本资料,测量身高及体质量,检测空腹血糖和血清中25-羟基维生素D_(3)的水平,探索患者血脂异常与血清维生素D水平的相关关系。结果2组患者的性别、BMI及血清25-羟基维生素D_(3)水平差异有统计学意义(P<0.05)。logistics回归分析显示,男性、超重或肥胖及血清25-羟基维生素D_(3)水平不足均为2型糖尿病患者发生血脂异常的独立危险因素(均P<0.05)。结论血清25-羟基维生素D_(3)水平不足是2型糖尿病患者发生血脂异常的独立危险因素之一,临床应重视2型糖尿病患者维生素D水平的监测,以利于早期预防和干预血脂异常。展开更多
