目的探讨MCI和正常老年人之间血脂水平以及与认知功能之间的相关性。方法选择石家庄市某社区老年人共213例，年龄≥60岁，其中MCI组40例，正常对照173例，分别评估MMSE、MoCA、ADL，并测血清甘油三酯(TG)、总胆固醇(CHOL)、高密度脂蛋白(HDL)以及低密度脂蛋白(LDL)水平，比较两组间的差异。并分析认知功能与血脂水平间的相关性。结果两组在血清TG水平上存在明显差异(2.27±2.001 vs.1.54±0.853，t=3.604，0.05)。发现MMSE(r=-0.105，=0.126)、MoCA得分(r=0.086，=0.213)与TG水平无明显相关性(>0.05)。结论 MCI与正常老年人可能存在TG水平差异，TG水平与认知功能无明显相关性。“,”Objective To explore the cor elation between blood lipid levels and cognitive function in MCI and normal elderly.Methods 213 community-based elderly people in Shijiazhuang were selected,which included 40 MCI and 173 normal.We assessed their cognitive function with MMSE,MoCA and ADL.Blood triglyceride (TG),cholesterol (CHOL),high density lipoprotein (HDL)and low density lipoprotein (LDL)were also examined and compared between the 2 groups.The cor elation between cognitive function and blood lipid levels was analyzed too.Results Significant dif erence was found in blood TG between the 2 groups(2.27±2.001 vs.1.54±0.853,t=3.604, 0.05).MMSE(r=-0.105, =0.126), MoCA (r=0.086, =0.213)and blood TG level ( >0.05).Conclusion There might be dif erence in blood TG between MCI and normal elderly but no significant cor elation was found between cognitive function and blood TG.
