Objective:
To investigate the association among demographic, physical, behavioural parameters, psychosocial and cognitive function in near-centenarians and centenarians.
Methods:
The present study data originated from the 2014 wave of the largest nationwide longitudinal survey of the population aged 95 and above in China (N = 175). The aim of this study was to systematically identify the relationship among physical and behavioural variables, negative emotions and cognitive function. Cognitive function was evaluated by the modified Mini-Mental State Examination (mMMSE) Chinese version. Structured responses were obtained for the analysis of physical and behavioural factors and negative emotions.
Results:
The average age of the sample was 98.78 years (SD = 4.00, range: 95-112 years). The average score of the mMMSE was 20.71 (SD = 3.48), average activities of daily living (ADL) total score was 17.21 (SD = 1.72), average instrumental activities of daily living (IADL) total score was 17.90 (SD = 5.57), and average negative emotion score was 8.77 (SD = 2.69). In the combined multiple linear regression model, the quality of sleep, IADL and negative emotion of centenarians were significantly associated with cognitive function (P < 0.05).
Conclusion:
The cognitive function of centenarians was significantly associated with the quality of sleep, IADL and negative emotion. Improving physical functioning and social resources can help emotional health and improve the overall cognition of centenarians.
