Though the environmental and medical conditions are very different, similar population characteristics can be observed in the developing countries. The mean age of the population is young. Most @entity1 have a rural way of life, but migrations towards towns result in a disorganized urbanization and in habits more predisposing to @entity65 . Care access is often difficult for the @entity1 . With respect to risk factors, smoking is increasing, @entity101 is highly prevalent and severe, a trend towards @entity28 is frequent in medium or high economical level @entity1 . S or C hemoglobin diseases seem to be associated with @entity301 . In spite of very insufficient statistical data, it appears that: @entity65 mortality is increasing when total mortality is decreasing: @entity63 and hypertensive @entity299 are increasing when streptococcal or nutritional @entity299 are stabilizing or decreasing. The authors seem to be the different developing countries in respect to the crossing of these curves. Some countries have not reached the crossing. Subsaharan Africa for instance. Others have gone beyond the crossing, some Asian countries for instance. Other countries seem to be at the intersection (Mediterranean or Latin American countries). But many countries suffer the double burden of increasing and decreasing diseases. There is a general lack of prevention owing to other competing priorities and also to economical, social and educational difficulties. However in some developing countries feasibility and efficacy of preventive measures have been proved.
