Abstract:
      目的 分析中老年人中甘油三酯葡萄糖指数(TyG)-腰围身高比(WHtR)(TyG-WHtR)与认知障碍的关联。方法 应用中国健康与养老追踪调查数据,以2011年和2015年的8 946名中老年人为基线人群,构建队列数据库。应用Cox比例风险回归模型估计中老年人基线TyG-WHtR不同水平与认知障碍风险的关联,并分别进行年龄和性别分层分析。结果 8 946名研究对象平均随访7.08人年,认知障碍发病密度为21.15/1 000人年。与TyG-WHtR的Q1水平相比,其Q3Q4水平分别使认知障碍风险增加32%(HR=1.32,95%CI:1.09~1.60)和47%(HR=1.47,95%CI:1.14~1.91)。趋势检验显示,认知障碍风险随TyG-WHtR水平升高而增加,且存在剂量-反应关系(P=0.001)。分层分析显示,45~59岁人群中,与TyG-WHtR的Q1水平相比,其Q3水平使认知障碍风险增加34%(HR=1.34,95%CI:1.02~1.78);≥60岁人群中,相比于TyG-WHtR的Q1水平,其Q3Q4水平分别使认知障碍风险增加31%(HR=1.31,95%CI:1.01~1.72)和63%(HR=1.63,95%CI:1.15~2.31);男性中,TyG-WHtR水平与认知障碍风险无统计学关联(P>0.05);女性中,相比于TyG-WHtR的Q1水平,其Q4水平使认知障碍风险增加76%(HR=1.76,95%CI:1.26~2.46)。结论 中老年人中较高的TyG-WHtR水平可增加认知障碍风险,且存在年龄、性别差异,早期的心血管健康管理和科学合理的体重管理对预防认知障碍具有重要意义。
English Abstract:
      Objective To explore the association between triglyceride glucose index (TyG)- waist to height ratio (WHtR)(TyG-WHtR) and cognitive impairment in middle-aged and elderly population. Methods A cohort database was constructed using the data from the China Health and Retirement Longitudinal Study, with 8 946 participants in 2011 and 2015 as the baseline population. Cox proportional hazards regression models were used to estimate the association between TyG-WHtR levels at baseline and the risk of cognitive impairment in middle-aged and elderly population. The analysis was stratified by age and gender, respectively. Results A total of 8 946 participants were included, with an average follow-up of 7.08 person-years and incidence density of cognitive impairment for 21.15 per 1 000 person-years. Compared with the Q1 level of TyG-WHtR, its Q3 and Q4 level increased the risk of cognitive impairment by 32% (HR=1.32, 95%CI: 1.09-1.60) and 47% (HR=1.47, 95%CI: 1.14-1.91), respectively. Trend test showed that the risk of cognitive impairment increased with the increase of TyG-WHtR level, and there was a dose-response relationship (P=0.001). Stratified analysis showed that in the population aged 45-59 years, compared with the Q1 level of TyG-WHtR, its Q3 level increased the risk of cognitive impairment by 34% (HR=1.34, 95%CI: 1.02-1.78). In the population aged 60 years and above, compared with the Q1 level, its Q3 and Q4 level increased the risk of cognitive impairment by 31% (HR=1.31, 95%CI: 1.01-1.72) and 63% (HR=1.63, 95%CI: 1.15-2.31), respectively. In the male group, there was no significant association between TyG-WHtR level and the risk of cognitive impairment (P>0.05). In the female group, compared with the Q1 level of TyG-WHtR, its Q4 level increased the risk of cognitive impairment by 76% (HR=1.76, 95%CI: 1.26-2.46). Conclusions Middle-aged and elderly population with a higher TyG-WHtR level may increase the risk of cognitive impairment, and there were age and sex differences. Early cardiovascular health management and scientific and reasonable weight management are of great significance to preventing cognitive impairment.
