摘要:
目的 探讨新疆伊犁地区60岁以上农村居民膳食炎症与衰弱的关系。 方法 2019年1―5月新疆伊犁地区霍城县招募的1 682名60岁以上居民为研究对象,进行问卷调查及体格检查,通过能量调整膳食炎症指数(energy-density dietary inflammatory index, EDII)和衰弱指数(frailty index, FI)评价其膳食炎症及衰弱状况,logistic回归分析模型分析膳食炎症与衰弱的关系。 结果 衰弱前期及衰弱患病率分别为50.65%和8.98%,男性、维吾尔族、文化程度低、家庭年均收入低、单身及体力活动少人群衰弱及衰弱前期患病率较高。EDII与衰弱和衰弱前期均相关,调整性别、民族、家庭年均收入、婚姻状况及体力活动后,随着EDII评分增大衰弱前期和衰弱患病风险有上升趋势(均P趋势 < 0.05),EDII按三分位数分组的T2、T3组衰弱前期和衰弱患病风险分别是T1组的1.37倍(95% CI: 1.04~1.82, P=0.027)和2.18倍(95% CI: 1.26~3.76, P=0.005)、1.32倍(95% CI: 1.02~1.72, P=0.036)和2.17倍(95% CI: 1.28~3.68, P=0.004)。 结论 膳食炎症与衰弱前期及衰弱相关,膳食可能通过炎症效应参与衰弱的发生发展。 Abstract:Objective This study aims to investigate the association between dietary inflammation and frailty among rural residents over 60 years old in Yili, Xinjiang. Methods A total of 1 682 residents over 60 years old were recruited from Huocheng County, Yili Region, Xinjiang, from January to May, 2019. A questionnaire survey and physical examination were conducted. Dietary inflammation and frailty of subjects were evaluated by energy-density dietary inflammatory index (EDII) and frailty index. A logistic regression analysis model was employed to analyze the relationship between dietary inflammation and frailty. Results The prevalence of prefrailty and frailty were 50.65% and 8.97%, respectively. These rates were higher among males, Uygurs, individuals with lower education levels, lower annual family income, those who were divorced, widowed, or unmarried, and subjects who engaged in less physical activity. After adjusting for gender, ethnicity, family annual income, marital status and physical activity, the risk of prefrailty and frailty increased with the EDII score (all Ptrend < 0.05). Individuals in EDII tertiles T2 (versus T1) were more likely to be pre-frailty (OR=1.37, 95% CI: 1.04-1.82, P=0.027) and frailty (OR=2.18, 95% CI: 1.26-3.76, P=0.005). Individuals in EDII T3 also had greater odds of pre-frailty (OR=1.32, 95% CI: 1.02-1.72, P=0.036) and frailty (OR=2.17, 95% CI: 1.28-3.68, P=0.004). Conclusions Dietary inflammation is associated with pre-frailty and frailty, and diet may participate in the occurrence and development of frailty through inflammatory effects. -
