Objectives:
This study examined whether older Chinese adults with different types of hukou status (government household registration system) exhibited different cognitive outcomes and whether receiving support from friends, an under-appreciated resource, helped mitigate the negative impacts of agricultural hukou status on cognitive health disparities.
Methods:
Using nationally representative data from the China Longitudinal Aging Social Survey, this study tested these relationships with well-validated measures.
Results:
Our results showed that older Chinese adults with agricultural hukou were more likely to have worse cognitive function than those with non-agricultural hukou. Further, friend support characteristics moderated the association between hukou status and cognitive function, whereby having better friend support was related to a weaker negative effect of agricultural hukou status on cognitive function.
Discussion:
The findings suggested that agricultural hukou status reflects the effects of accumulated disadvantage across the life course with negative consequences for late-life cognition. The cognitive health disparities between agricultural and non-agricultural residents may be reduced in the context of a higher level of friend support, supporting a stress buffering hypothesis.
