For years, people believed that good health is a direct result of strong economic development. How ever, this study suggests the opposite is true. It says that strong economic development is an important result of improved health. An international committee of economists and experts in public health and policy carried out the study. It is based on almost ninety investigations in countries a round the world. Some people say the study is the most complete examination to link investments in health care to economic growth. The study calls for a large increase in foreign aid for health care services in developing countries. In the world's richest countries, total spend ing for health care for each person is almost two-thou sand dollars a year. However, in the world's poorest nations, spending on health care for each person is only thirteen dollars a year. The WHO says this amount should be increased to thirty-eight dollars a year for each person. The money would help poor nations provide treatment for disease. It would also provide babies with important health care early in life. (27)
