Abstract:
Objective To investigate the association between dietary behavior and mild cognitive impairment(MCI)in older adults,and to further analyze the role of cardiometabolic comorbidities in this relationship.Methods A total of 6599 older adults were recruited from 3 communities and 48 villages in Dawu County between 2018 and 2023 as part of the Hubei Elderly Memory Cohort Study.Dietary behaviors were assessed using a food frequency questionnaire and a dietary behavior questionnaire.Latent class analysis was performed to categorize the participants into healthy eat-ing behavior(HEB),sub-healthy eating behavior(SHEB),and unhealthy eating behavior(UEB).Cardiovascular-metabolic diseases were diabetes,hypertension,coronary heart disease,and cere-brovascular disease,which all diagnosed by physicians.MCI was diagnosed by a team of clinical experts according to Peterson's criteria.Multivariable logistic regression model was used to ana-lyze the impact of cardiometabolic comorbidities on the association between dietary behavior and MCI.Results The morbidity rate of MCI was 24.3％,and that of HEB,SHEB and UEB was 16.6％,24.3％and 31.3％,respectively.The incidence of MCI was higher in the participants who were female,over ≥75 years old,unmarried,and lack physical exercise,SHEB and UEB groups,had low educational level,lived in rural areas,had no stable income,had abnormal BMI,and more types of cardiometabolic diseases(P＜0.05,P＜0.01).After adjusting for confounders,multivari-able logistic regression analysis indicated that both UEB(OR=1.220,95％CI:1.004-1.418,P=0.045)and SHEB(OR=1.592,95％CI:1.345-1.883,P=0.001)were positively correlated with MCI risk in older adults.Further stratified analysis by cardiometabolic comorbidities revealed that for the patients in the HEB group,those suffering from hypertension+diabetes+coronary heart disease had the highest risk for MCI(OR=4.220,95％CI:1.913-9.309,P=0.001),while for the SHEB group,the following comorbidities were significantly associated with increased MCI risk:hypertension+diabetes(OR=1.640,95％CI:1.157-2.322,P=0.005),hypertension+cerebro-vascular disease(OR=1.454,95％CI:1.041-2.031,P=0.028),hypertension+diabetes+cere-brovascular disease(OR=2.064,95％CI:1.246-3.419,P=0.005),and hypertension+diabetes+coronary heart disease+cerebrovascular disease(OR=1.974,95％CI:1.036-3.760,P=0.039).Conclusion Older adults with SHEB or UEB have a higher risk of developing MCI,and the pres-ence of cardiometabolic comorbidities further exacerbates this risk.
