Associations between social networks, social contacts, and cognitive function among Chinese nonagenarians/centenarians
Abstract
Objective To explore the associations between social networks, social contacts, and cognitive impairment in the very elderly aged 90-108 years.Methods Data were from subjects of the Project of Longevity and Ageing in Dujiangyan, China. The socio-demographic, social networks, and social contacts data were collected and cognitive function was assessed in all subjects using the Mini-Mental State Examination (MMSE).Results 764 Chinese nonagenarians and centenarians (67.41% women, mean age 93.47 years) were included. The mean MMSE score was 14.99 ± 5.93). The prevalence of cognitive impairment was 64.53%. The mean social contact score was 4.37 ± 1.86. There were significantly different cognitive function scores among individuals with different marital status, number of close friends, and different social contact levels (all P<0.05). Spearman rank correlation analysis showed that number of close friends and social contact scores were significantly positively but single status was significantly negatively correlated with the MMSE scores (all P<0.05). Multiple logistic regression analysis showed that there were associations between single status, no close friend, and low level of social contact with cognitive impairment (all P<0.05), but not other social network variables.Conclusion Single status, no close friend, and low level of social contact were associated with increased risk of cognitive impairment in Chinese nonagenarians and centenarians. Our finding might add new information for social networks, social contacts, and cognitive research in the elderly.

People who live alone and are unable to complete household tasks due to poor cognitive function or health are unlikely to manage independently at home and may be more likely to move into a care home.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
