Spatio-temporal distribution of human lifespan in China.

Wang S, Luo K, Liu Y - Sci Rep (2015)

Bottom Line: The spatial autocorrelation analyses indicate less spatial dependency and several discontinuous clusters regions of high-CH and LI areas.The factors of temperature, topography and wet/dry climate lack of significant influence on CH and LI.It can be inferred that, in addition to genetic factor and living custom, some unique and long-term environmental effects may be related with high or low values of CH and LI.

ABSTRACT
Based on the data of latest three Chinese population censuses (1990-2010), four lifespan indicators were calculated: centenarians per one hundred thousand inhabitants (CH); longevity index (LI); the percentage of the population aged at least 80 years (ultra-octogenarian index, UOI) and life expectancy at birth (LEB). The spatio-temporal distributions of data at Chinese county level show that high-longevity areas (high values of CH and LI) and low-longevity areas (low CH and LI values) both exhibit clear non-uniformity of spatial distribution and relative immobility through time. Contrarily, the distribution of UOI and LEB shows a decline from the east to the west. The spatial autocorrelation analyses indicate less spatial dependency and several discontinuous clusters regions of high-CH and LI areas. The factors of temperature, topography and wet/dry climate lack of significant influence on CH and LI. It can be inferred that, in addition to genetic factor and living custom, some unique and long-term environmental effects may be related with high or low values of CH and LI.

Mentions: The world average CH-value is 5.1 in 201013. Since the 1950s, the number of centenarians in industrialized countries doubled every ten years approximately, and from the early 1950s to the late 1980s, the average annual growth rate of centenarians was about 7% in these countries14. The national population censuses in China reveal a similar increasing trend of the indicators such as CH, LI, UOI and LEB (Fig. 1). The indicators such as UOI and LEB of China are close to or even exceed the world average level. In contrary, the CH and LI are obviously lower than the world average values (Fig. 1).
