Cognitive Function Among Noncustodial Grandparents in China and the United States: A Cross-National Perspective

The current study aimed to investigate the association between grandparenting and cognitive function over time in noncustodial grandparents in China and the United States. Lagged dependent variable (LDV) approach and linear regression models were applied to analyze a sample of 1,411 Chinese and 6,579 American adults aged 65 and above from the China Health and Retirement Longitudinal Study (CHARLS, 2011–2013) and the U.S. Health and Retirement Study (HRS, 2012–2014). Grandparenting involvement was associated with less decline in episodic memory for grandparents and greater level of grandparenting had no negative effect on mental status and global cognitive function in noncustodial grandparents in China and the United States. The impact of grandparenting on cognitive function was conditioned on caregiving intensity, gender, urban/rural residence, and nation. Findings of the study suggest that greater attention on grandparenting facilitation might yield improved research, social support, policy, and interventions on cognitive health for the general older population.
