The term social ecology refers to the nested arrangement of family, school,
neighborhood, and community contexts in which children grow up. In this ch
apter, new directions in public health science as reflected in the theoreti
cal and methodological implications of the concept are explored. The contri
butions of this ecologically oriented approach to child health practice, de
signed as it is from a health promotions perspective, are considered. A cri
tique of the term social capital is also presented because of its growing p
opularity in matters of child health. The point is made that application of
this vague term carries the serious risk of misspecifying social phenomena
. Future trends in the promotion of child well-being are in a position to f
lourish given the confluence of advances in theory, methods, and analytical
capacity. The capacity to benefit children is also enhanced as public heal
th science aims to translate the principles of child rights into health pra
ctice and policy.
