Study On The Relationship Between Dietary Inflammatory Index And Frailty In The Elderly

Objective:(1)Observe whether there is a difference in the elderly's frailty among different dietary inflammatory index groups;(2)Analyze the relationship between the dietary inflammatory index and the elderly's frailty,and assess whether the pre-frailty patients can be reversed by diet;(3)Evaluate the dietary inflammatory index impact on frailty,have a view to provide early intervention and guidance to frailty elderly through diet,thereby improving the quality of life of the elderlyMethods:From June 2019 to December 2019,a cross-sectional study was carried out in 320 elderly patients who met the acceptance and discharge standards in a community health service center in Xi'an.The general clinical data,score of dietary inflammation index and frailty of the elderly were collected.Ask the diet data recalled by the elderly within 3 days,calculate the content of each diet according to the Chinese food composition table(2009),and calculate the score of individual dietary inflammation index according to the internationally unified formula of dietary inflammation index.The score is positive for promoting inflammation diet,negative for anti-inflammation diet,0 for neutral diet,and divide the dietary inflammatory index into anti inflammatory group and promoting inflammatory group was divided into four groups(Q1?-1.76,-1.75?Q2?0.57,0.58?Q3?1.64,Q4?1.65)according to the quartile grouping.The elderly were divided into non debilitating group,pre debilitating group and debilitating group by using the debilitating phenotypes proposed by fried,including low weight,self-reported fatigue,grip strength reduction,walking speed reduction and physical strength reduction.Students't test,ANOVA,chi square test,Pearson product moment correlation analysis and other statistical methods were used to analyze the data,and to explore the relationship between the dietary inflammatory index and the decline of the elderly.Results:(1)In the comparison of debilitating phenotype between the debilitating group and the pre debilitating group,the differences of self-reported fatigue,low physical activity and slowing down of walking speed were statistically significant(P<0.05).(2)The scores of different debilitating degrees and dietary inflammatory index scores were-0.589,2.552 and 3.216,respectively with statistically significant differences(c~2=18.416,P<0.001).(3)Anti-inflammatory diet group and pro-inflammatory diet group There was significant difference between groups and in different degrees of debilitation(c~2=12.631,P<0.001);(4)There was a positive correlation between the dietary inflammatory index and the debilitation of the elderly(r=0.507,P<0.05).The variables such as age,weight,gender and education were controlled.The partial correlation between the dietary inflammatory index and the debilitation of the elderly was analyzed,and the positive correlation between the two was(r=0.412,P<0.05);(5)The correlation analysis of the elderly's debilitation and general variables showed that the elderly's debilitation was positively correlated with age,BMI,education level,history of coexistence of chronic diseases and history of taking medicine,the correlation coefficients were 0.125,0.033,0.217,0.324,0.016,P<0.05,and negatively correlated with drinking history,the correlation coefficient was r=-0.357,P<0.05,and gender,height,weight,marriage There was no significant correlation among marriage status,smoking history and monthly income(P>0.05).Conclusions:(1)There are differences in the scores of dietary inflammatory index among different degrees of debilitation;(2)There is a positive correlation between the dietary inflammatory index and the elderly's debilitation.The higher the score of dietary inflammatory index is,the higher the prevalence of the elderly's debilitation is,and the lower the score of dietary inflammatory index is,the lower the incidence of the elderly's debilitation is.
