Vulnerable Populations: Definitions And Determinants

The debate over reauthorization of the State Children’sHealth Insurance Program has widely become viewed as a proxycrystallizing today’s philosophical divide regarding solutionsto covering the uninsured. The magnitude of the tumult, however,also illustrates what those in the public health and socialscience communities have bemoaned for years: that the centerof gravity for public policy initiatives intended to improvethe health status of the most vulnerable has remained fixedon improving access to care. Far less consideration has beengiven to equally important "upstream" factors affecting theoverall health of the population, including socioeconomic status,education, and the built environment. For proof that the UnitedStates has voted with its collective feet in overemphasizingthe medical model, one need only recall that roughly 95 percentof the health care economy pays for medical care, with onlythe balance addressing nonmedical determinants of health.

In 1987 Health Affairs published a thematic issue devoted tohealth and poverty, focusing on the needs of many of the samegroups that we would now normatively term "vulnerable." At thattime, addressing these needs was largely synonymous with improvingaccess to care. Since then, however, although much has beenlearned about the extent to which nonmedical determinants mediateoverall health status, such knowledge has not largely permeatedhealth policy levers. What accounts for this continued disconnect?Beyond a sheer "awareness gap," the desire to postpone perceivedthorny discussions of how to achieve greater socioeconomic equitymight also contribute to the dearth of public commitment tomore comprehensively addressing the additional arbiters of poorhealth.

The papers that follow attempt to refocus the conversation byimparting greater insight into what is meant by vulnerability,its determinants, and policies that may be applied to improvethe overall health status of at-risk groups. First, David Mechanicand Jennifer Tanner identify individual and communal factorsthat may serve as points of entry for policymakers seeking toreduce overall health vulnerability. Perspectives by Bruce Vladeckand Tom Miller follow. Next, Alice Furumoto-Dawson and colleaguesdeconstruct the complex biological and environmental interactionsat work in childhood that potentially contribute to poor healthstatus later in life. Richard Epstein and Paula Lantz and colleaguesalso weigh in with Perspectives. Then, Kathryn Derose and colleaguesdescribe the unique barriers heightening the risk of poor healthamong immigrant populations seeking needed care. Finally, DennisAndrulis and colleagues examine the extent to which minoritycommunities are integrated into emergency preparedness planningefforts and point to potential models for optimal future initiatives.
