During the ongoing national discussion of proposals to reform health c
are financing, effects on the health status of children emerged as a s
pecial concern. Public attention has shifted away from comprehensive r
eform of the health care system and toward reform of the welfare syste
m (primarily the Aid to Families with Dependent Children [AFDC] progra
m), but this debate with its focus on parental behavior has not attend
ed to the effects of reform on children's health and well-being. Yet t
he changes proposed will have a profound effect on the lives of childr
en. Children's health status is determined by a multiplicity of factor
s, among which social and economic factors are especially important.(1
,2) Children living in poverty have poorer health than their more affl
uent peers,(1-16) consequently, welfare system reform carries great im
plications for children's health, Welfare system reforms that reduce r
esources for low-income families will lead to a predictable increase i
n adverse health outcomes for children in low-income homes. Pediatrici
ans and other children's health professionals must view this process w
ith great concern. This commentary addresses the associations of pover
ty and children's health, the potential adverse consequences for child
ren's health with the welfare system reform measures currently being e
nacted, and the subject of welfare system reform as human experimentat
ion.
