Aim We explored the association between family functioning and cognitive impairment in the very elderly aged 90–108 years. Methods The present study comprised data from subjects included in the 2005 P roject of L ongevity and A ging in D ujiangyan, C hina. Sociodemographic and family functioning data were collected, and cognitive function was assessed in all subjects using the M ini‐ M ental S tate E xamination. Results Data from 699 C hinese nonagenarians and centenarians were included. The prevalence of cognitive impairment was 62.8%. The prevalence of family dysfunction was 52.2%, including 8.6% severe and 43.6% moderate dysfunction. There were significant differences among individuals with different family functioning level with regard to cognitive function scores ( P = 0.005) or cognitive impairment prevalence ( P = 0.012). Subjects with cognitive impairment had lower family functioning scores than those without cognitive impairment ( P = 0.004). Pearson's correlation analysis showed that family functioning scores were correlated with M ini‐ M ental S tate E xamination scores ( r = 0.13, P = 0.001). Multiple logistic regressions showed that severe family dysfunction was a risk factor for cognitive impairment. The effect remained after adjusting for sociodemographic status, life habits and metabolic indicators. Conclusions Family functioning was related to cognitive impairment among C hinese nonagenarians and centenarians. We found that the higher the family functioning scores, the higher the M ini‐ M ental S tate E xamination scores. Severe family dysfunction was associated with increased risk of cognitive impairment.
