Although child labor is recognized as a global health problem, research on its health impact on children has been limited and sometimes inconsistent. In 1998, Graitcer and Lerer published the first comprehensive review of the effect of child labor on children’s health by extrapolating data from the Global Burden of Disease Study.15 The occupational mortality rate among children matched the adult occupational mortality rate, such that the occupational mortality rate indicates mortality associated with child labor. In another study, in 2000, Graitcer and Lerer did not find any differences in the health status of working and nonworking Egyptian children in the short run (the children were not followed to adulthood).16 A 2003 report on children’s work in Morocco,17 Yemen,18 and Guatemala,19 and a review developed under the aegis of Understanding Children’s Work Project20 provide an overview of the nature and extent of child labor, its determinants, and its consequences for the health and education of children in these countries. Several case–control and cohort studies have reported on the association of child labor, impaired growth, and malnutrition
