Social factors—particularly residential
segregation and neighborhood quality—contribute to racial disparities
in the death rates of white and Black Americans, according to an
analysis by researchers at the University of Michigan and Indiana
University. Large disparities persist for deaths due to homicide, heart
disease and cancer, according to U-M researcher David R. Williams and
IU researcher Pamela Braboy Jackson, who tracked changes in Black and
white deaths from five conditions over a 50-year period. But the gap
has narrowed for deaths from the flu-pneumonia and suicide. The
analysis appears in the March/April 2005 issue of Health Affairs. "We
need to rethink what constitutes health policy in this country," said
Williams, a sociologist at the U-M Institute for Social Research (ISR).
"Given the broad social determinants of health and mortality, policies
far removed from traditional health policy can have decisive
consequences." Among the major findings:
Heart Disease & CancerThe racial gap in homicide death
rates narrowed between 1950 and 2000, but the homicide rate (the 15th
leading cause of death in the U.S.) was still almost six times greater
for Blacks than for whites.
Homocide
The racial gap in homicide death rates narrowed between 1950 and 2000,
but the homicide rate (the 15th leading cause of death in the U.S.) was
still almost six times greater for Blacks than for whites.
For flu and pneumonia,
the seventh-leading cause of death, large racial differences in death
rates existed in 1950, with Black mortality 70 higher than that of
whites. Over the last half-century, striking declines in death rates
occurred for both races, with larger declines for Blacks than for
whites. "The virtual elimination of a racial disparity in death rates
from flu and pneumonia is a result of the ready availability of
treatment facilitated by Medicare and Medicaid," noted Jackson. "Social
variations in motivation, knowledge and resources played a small role
in eliminating a large disparity in health."
For suicide,
the 11th leading cause of death, Black death rates have consistently
been less than white death rates. "High levels of self-esteem and
religious involvement in the Black community are potential contributors
to the better suicide and mental health profile of Blacks," noted
Williams.
Williams and Jackson maintain that
racial differences in socioeconomic status, neighborhood residential
conditions and medical care are important contributors to continuing
racial differences in death rates from heart disease, cancer and
homicide. Education, income and health practices, including diet,
physical activity, tobacco use and alcohol abuse, all play a role in
racial differences in disease and mortality, they point out. But other
factors also come into play. For example, the homicide death rate for
African-American men with at least some college education is 11 times
that of similarly educated whites. "Strikingly, the homicide rate of
black males in the highest education category exceeds that of white
males in the lowest education group," the authors write. [more]
