             [摘    要] 目的:探讨中国内脏脂肪指数(Chinese visceral adiposity index,CVAI)与认知能力障碍(cognitive impairment,CI)的
              相关性,并进一步分析不同年龄分层下两者的相关性,为准确评估两者关系,提供新的可干预的认知功能影响因素提供依据。
              方法:选取CHARLS数据库2011年和2015年的数据,包括研究对象的性别、年龄、教育程度、饮酒、吸烟史以及体重指数和生化
              指标。应用Logistic 回归分析CVAI与CI的相关性,并根据不同年龄进行分层分析。结果:①在12 102例研究对象中,认知能
              力障碍者为1 295例(10.7%);②在≥65岁人群中,CVAI与CI具有相关性(P < 0.05),而在<65岁人群中CVAI与CI无明显相关
              性;③利用截断值(161.94),所有研究对象可分为高CVAI组(CVAI≥161.94)和低CVAI组(CVAI<161.94);④年龄与CI呈正相
              关(OR=2.24,95%CI:1.66~3.03),教育程度与CI呈负相关(OR=0.71,95%CI:0.53~0.94),在≥65岁人群中,高CVAI与CI呈正相
              关(OR=1.91,95%CI:1.24~2.93)。结论:CVAI、年龄、教育程度均与CI相关。在65岁及以上人群,高CVAI是CI的危险因素。

             [Abstract] Objective:The current study aims to explore the correlation between Chinese visceral adiposity index(CVAI)and
              cognitive impairment(CI),and further to analyze the correlation between CVAI and CI under different age levels,providing evidence
              for accurately evaluating the relationship between CVAI and CI,and seeking for new factors available for intervention associated with
              CI. Methods:The CHARLS database was used in the current study. The baseline data of 2011 and 2015 were collected,including
              gender,age,education level,alcohol consumption,smoking history,body mass index,and biochemical indicators. Logistic regression
              analysis was used to analyze the correlation of CVAI and CI,according to difterent age stratification. Results:①A total of 12 102
              subjects were included in the curreut study,1 295(10.7%)subjects had CI. ② There was a correlation between CVAI and CI in people
              aged 65 and above(P < 0.05),but no significant correlation between CVAI and CI in people aged below 65(P > 0.05);③The best cut⁃
              off value of CVAI for CI was 161.94. According to the cut⁃off value,all subjects was divided into high CVAI group(CVAI≥161.94)and
              low CVAI group(CVAI<161.94). ④ Age was positively correlated with CI(OR=2.24,95% CI:1.66-3.03),education level was
              negatively correlated with CI(OR=0.71,95%CI:0.53-0.94),and high CVAI was correlated with CI in people aged 65 and above(OR=
              1.91,95%CI:1.24-2.93). Conclusion:CVAI,age and education were correlated with CI. High CVAI is a risk factor for CI in people
              65 years and older.
