Abstract

Abstract

Objective To explore the relationship between socioeconomic status (SES) and mild cognitive impairment (MCI) in older adults. Methods We utilzed the data from the Hubei Memory and Aging Cohort Study (HMACS). A total of 7 787 older adults ≥65 years old were included, who had completed a complete set of neuropsychological assessments and clinical physical examinations. SES was measured by factors such as education level, occupation, and monthly household income per capita. MCI was diagnosed by a panel of experts following Petersen′s MCI standard and Chinese Diagnostic guidelines for dementia and Cognitive impairment. A multivariate logistic regression was used to analyze the association between SES and MCI in older adults. Results Out of the 7 887 respondents (average age of 71.74±5.58 years), the prevalence of MCI was 23.00% (95% CI: 22.07%-23.93%). MCI prevalence was highest among the low SES group at 44.65%, followed by the middle SES group (16.89%) and the high SES group (9.18%); it was more prevalent among women than men, and more common in rural areas compared to urban ones. Stratified analysis revealed that, compared to their high SES counterparts, the risk of MCI was 6.276 times higher among low SES urban males (OR=6.276, 95% CI: 4.017-9.805) and 3.978 times higher among low SES urban females (OR=3.978, 95% CI: 2.943-5.376). Among rural female older adults, the distribution of SES was significantly uneven according to existing SES standards. Conclusions Older adults with lower SES have a higher prevalence of MCI. Therefore, MCI prevention strategies should particularly focus on community-dwelling older adults with lower income and educational attainment.
