[Demographic changes and health management].

Since our Constitution declaration in 1978 and General Law for Health in 1986, to date, the Spanish society has undergorne marked social changes. Socio-economic and health indicators in Spain have also improved as to an increased life expectancy, important reduction in infant mortality, and favourable changes reported in the national Health Survey. Risk factors influence the main causes of death, thus it is said that "man does not die but it kills himself". Healthy health practices are specified, and there is empirical evidence of greater disability-adjusted life years, a better adherence to Mediterranean diet, no smoking, moderate consumption of alcohol, enough time of sleeping, weight control, avoiding obsity and overweight, and increased physical activity, all the above practices achieving a healthier life. At a global scale in the world we live, famine has no frontiers, and fighting against this plague can not await longer. Overall, health and poverty are correlated and it must be overcome for reasons of human dignity, universal rights (even in ius gentium), and ethical dimension as normative of new socio-economic structures. Present must be transformed to recover hope in ou global world, still hungry, and in need of justice, enlightenment and solidarity.
