TY - JOUR T1 - Children and violence: The world of the defenseless AU - Bell CC Y1 - 2009/08/05 N1 - 10.1001/jama.2009.1128 JO - JAMA SP - 573 EP - 574 VL - 302 IS - 5 N2 - In part 1, Helander presents the tremendous magnitude of the problem, concluding that “half of the world's population have been victims of childhood violence before the age of 18” (p 4), and he provides an excellent discussion of the definitions, materials, and methods determining his conclusions. It becomes clear that getting information about this ubiquitous worldwide problem is not an easy task. Surveillance of these commonplace problems (eg, 300 million children worldwide go hungry each day) is challenging, owing to the difficulty of getting reliable information from developing countries, where population growth abounds. “Mirrors of the Past” provides an astounding history of childhood trauma over the centuries.
