Quantitative Evaluation and Analysis on Human Health Risk

Health condition is related to the economic and social development of a country and the whole world. We concluded that the influencing factors of health risk include environment pollution, food security, disease threat and health care condition, and then an indicators system is put forward in the paper. Based on the foundation of the indicators system, 40 countries were chosen to evaluate the condition of human health risk. With the method of Hierarchical Cluster Analysis, 40 countries were divided into four groups, and we analyzed the characteristic of each group. Compared with other countries at the similar development level of economy, the human health risk of China is much higher. We analyzed the correlation between human health risk and the economy development level, and then we concluded that a country should attach importance to improving the condition of human health, when the GNI per capita is between $ 1000 and 3000 US dollars. The stage is vital for economy development, and also for the improvement of the human health condition. We found that countries with high human health risk are mostly in Africa and Asia. The developed countries should help the developing countries reduce the human health risk for a win-win situation of the development of the whole humanity.
