National health system reform, launched in 2000, has initiated the new concept of civil involvement in public policy processes. It advocates the development of health public ( or putting health into non – health sectors ) to pursue the principle of “all for health” in order to achieve the ultimate goal of health for all. The novel mechanism of HIA has to be created to mediate between all stakeholders of any public policy, so that they work together for a healthier society based on sound evidence.
