Widowhood Shock, Family Reconstruction, and Mild Cognitive Impairment Among Older Adults: A Prospective Cohort Study.
Mild cognitive impairment (MCI), especially among widowed older adults, is increasingly urging public concern. This study aimed to investigate the association of widowhood, remarriage, and widowed life characteristics with the MCI risk among Chinese older adults. With an average age of 86.49 ± 10.20, a sample of 5377 participants aged between 65 and 116 was collected from four waves of the Chinese Longitudinal Healthy Longevity Survey between 2008 and 2018. Cox proportional hazards models and restricted cubic spline models were employed to estimate and plot the associations. Results showed that widowhood is associated with an increasing MCI risk, which could not be alleviated by remarriage. This negative impact was pronounced among women and those at older age. The association of living alone duration after widowhood and MCI onset displayed an inverse U-shape, with a peak risk at the 10th year. These findings have practical implications for pointing out the most vulnerable groups to MCI.
期刊介绍：
The Journal of Applied Gerontology (JAG) is the official journal of the Southern Gerontological Society. It features articles that focus on research applications intended to improve the quality of life of older persons or to enhance our understanding of age-related issues that will eventually lead to such outcomes. We construe application broadly and encourage contributions across a range of applications toward those foci, including interventions, methodology, policy, and theory. Manuscripts from all disciplines represented in gerontology are welcome. Because the circulation and intended audience of JAG is global, contributions from international authors are encouraged.
