As the world has urbanized, public health needs have changed. For most of the 20th century, epidemiologists worried about communicable diseases killing very young children. Now, a new paper in the journal the Lancet suggests, the bigger concern in many countries is mortality among young adults ages 15 to 24 -- especially young men. Modernization and urbanization may have pushed back disease. But they have made accidents, suicide and violence more common causes of death during the second decade of life.
To investigate the mortality trends, researchers led by Dr. Russell Viner of the University College London Institute of Child Health looked at the World Health Organization's mortality database from 1955 to 2004, breaking out data by age group and sex in 50 countries with good mortality data. These included nations with low-, middle- and high-income levels.
Over the study period, mortality from all causes was reduced by as much as 93% in children 1 to 4 years old, the study reported. But young men ages 15 to 24 experienced a decline in mortality of just 41% to 48%. In the period 2000-2004, mortality among young men was two to three times higher than that among young boys, the researchers said. By the late 1970s, injury was the dominant cause of death in young men. Violence and suicide accounted for one-quarter to one-third of mortality in young men between 2000 and 2004.
