Lifestyle of Chinese centenarians and their key beneficial factors in Chongqing, China.

OBJECTIVE
This study aims to describe the lifestyle of Chinese centenarians and to identify the beneficial factors that are correlated to their longevity.


METHODS
A census-based survey was conducted among centenarians in Chongqing, Southwest China, to identify the lifestyle factors affecting their health. From screening identification cards, 878 centenarians (age range 100-117, mean 102) were identified and interviewed.


RESULTS
The survey indicated that 64% centenarians were able to take care of themselves. The majority of centenarians were nonsmokers (92%) and non-drinkers (83%). No significant difference was observed between urban and rural distributions (Χ2=0.939, p=0.625). Moreover, 43% centenarians maintained a regular diet, and only 33% had a sedentary lifestyle.


CONCLUSIONS
A nutritious diet, adequate physical exercise, and a harmonious family environment may be the key lifestyle factors for their longevity of centenarians in Chongqing. These observations might be helpful in designing health promotion and welfare strategies for the elderly.
