title: Community-Based Study of the Relationship Between Social Capital and Cognitive Function in Wuhan, China.
abstract: The present study aimed to detect the association between social capital and cognitive function in elderly residents with/without mild cognitive impairment (MCI) in Wuhan, China. A cross-sectional study was conducted for data collection in 2014. A sample of 1156 participants entered the study. Cognitive function was assessed using the Chinese version of the Montreal Cognitive Assessment. A modified instrument scale was used to measure bonding and bridging social capital. The results indicated that participants without MCI had higher social capital scores (45.2 ± 8.3) than those with MCI (37.0 ± 6.3; P < .001). With adjustments for relevant confounders, the multiple logistic regression model showed that participants with a bonding social capital score that ranged from 17 to 24 had an odds ratio (OR) for MCI of 0.38 (95% CI = 0.04-0.79); those with a score that ranged from 25 to 32 had an OR for MCI of 0.36 (95% CI = 0.04-0.70); and those with scores ≥33 had an OR for MCI of 0.25 (95% CI = 0.03-0.53). In conclusion, we found a statistically significant inverse association between bonding social capital and MCI, which suggests that shortage of social resource from homogeneous social networks might be associated with cognitive decline.
