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: Based on the latest three national population censuses in China at county-level, the lifespan indicators in south China were persistently slightly higher than those in north China, except LEB in 2010 (Table 1). The values of lifespan indicators in Tibetan area were obviously lower than both of north and south China in view of the census in 2010 (for data quality see methods part). Obvious geographical distribution of UOI and LEB shows a clear decline from the east to the west rather than difference between North and South China (Fig. 2). CH and LI values exhibit scattering and cluster distribution (Fig 2). Distribution of CH and LI is characterized by skewness of the distribution, while distribution of UOI and LEB approximately exhibits a normal distribution (Fig 3). In addition, these distribution patterns changed little across time.
