摘要：In the world’s wealthiest country, poverty and poor health are the experience of far too many American children. Over one-fifth of all children in the United States live in families whose incomes are below the poverty line. The poverty rate for U.S. children is higher than for any other industrialized country (Blank, 1997). Lower incomes are linked to poor health through a variety of factors. Per capita health expenditures on preschool children are the lowest of any age group. This is only due in part to the fact that children of this age are not prone to expensive diseases such as cancer or heart disease. Moreover, this age group is one of the least studied by the medical community (Wolfe and Sears, 1997).
