Abstract
PURPOSE The aim of this study was to evaluate the association of marital status with cognitive function and to examine the potential effect modifiers in Chinese hypertensive populations. METHODS A total of 9,525 adult Chinese hypertensive patients were enrolled in this cross-sectional study. Cognitive function, as the dependent variable in our study, was assessed by the Chinese version of the Mini-Mental State Examination (MMSE). We adjusted for potential confounding factors in multiple linear regression models to examine the relationship of marital status with cognitive function. In addition, we divided the population according to sex to explore whether there were sex-specific differences. RESULTS Among the 9,525 study participants, the mean (SD) age for men was 63.5 (10.3) years, and the mean MMSE score was 24.9 ± 5.0, whereas for women, the mean (SD) age was 63.8 (9.3) years, and the mean MMSE score was 19.4 ± 6.4. Unmarried persons had lower scores on the MMSE and lower subscores in each of the cognitive domains. A stronger correlation between marital status and a lower MMSE score was statistically significant in men (unmarried men: β = -1.55; 95% CI: -1.89, -1.21) but not women (unmarried women: β = -0.22; 95% CI: -0.56, 0.12; p interaction = 0.006). Compared to men who were widowed or divorced, never married men were more likely to have lower MMSE scores (β = -2.30, 95% CI -3.10,-1.50; p < 0.001). CONCLUSIONS Our study demonstrated that being unmarried is an extremely important but neglected social risk factor for cognitive function. Sex was a strong effect modifier: being unmarried was correlated with a higher risk of cognitive decline than being married in Chinese hypertensive men, especially among older men, but this correlation was not observed among women. Moreover, never married men showed poorer cognitive function than those who were divorced or widowed.

The association of marital status with cognitive function and the role of gender in Chinese community-dwelling older adults: a cross-sectional study. Aging Clin Exp Res 2021; 33:2273-2281. [PMID: 33156506 DOI: 10.1007/s40520-020-01743-5] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Accepted: 10/19/2020] [Indexed: 12/25/2022]
Abstract
BACKGROUND Evidence of the association between marital status and cognitive function in Chinese older adults is limited. AIMS To examine the relationship between marital status and cognitive function and to explore the role of gender amongst older adults from three Chinese communities. METHODS A total of 1376 participants aged 60 years or over were included in this cross-sectional study. Cognitive function was assessed using the Chinese version of the mini-mental state examination (MMSE). Marital status and other variables were collected using a standardized questionnaire. Multiple linear regression models were used to examine associations between marital statuses and cognitive function amongst the target population. The moderating role of gender in these potential associations has also been explored. RESULTS In univariate linear regression models, compared to being married, both being widowed (β [95% CI]: -1.46[-2.78 to - 0.13]) and being single (β [95% CI]: - 4.88[-6.43 to - 3.38]) were associated with lower MMSE scores. After adjustment for confounding factors, the significant association of being widowed with MMSE scores disappeared (β [95% CI: - 0.08[- 1.04 to 0.86]), but the association of being single with MMSE scores still existed (β [95% CI]: - 1.87[- 3.17 to - 0.58]). Furthermore, the association of being single with MMSE scores was statistically significant in men (β [95% CI]: - 5.25[- 7.17 to - 3.33]) but not in women (β [95% CI: 0.88[- 0.87 to 2.64]). DISCUSSION AND CONCLUSIONS Being single was associated with poorer cognitive function compared with their married counterparts in older Chinese men but not in women. More preventive measurements should be implemented for single men to reduce or delay cognitive decline. This is particularly important in the context of an aging population in China.
