Spatial non-equilibrium and distribution dynamic evolution of the development level of national health in China’s provinces

Background Physical health is the material basis of a country’s socio-economic development, and an in-depth study of the spatial pattern and dynamic evolution of the distribution of national physical fitness in China is of great practical significance for improving national physical fitness. Methods Based on the national health physique monitoring data of 31 provinces (cities, districts) in China in 2005, 2010 and 2015, the Gini coefficient and its decomposition method and nonparametric density estimation method were used to study the population, males, females, urban and rural nationals in China. Spatial non-equilibrium characteristics and dynamic evolution trend of healthy physique development level. Results The regional disparities in the development level of health and physique among the general, female, urban and rural nationals in China all show a trend of narrowing at first and then expanding.There is obvious heterogeneity in the regional disparities in the development level of national health and physique within the three regions of East, Middle and West. The distribution of the nuclear density curve of the development level of the Chinese national health constitution showed a dynamic characteristic of evolution from a “spiky, multi-peak” shape to a “broad-peak, single-peak” shape. Conclusions The low-level provinces have the characteristics of “club convergence”. However, there is a “catch-up effect” between provinces with low levels of rural national health and physique development.
