David
Abrams:
"As we learn more about our genes and the biological vulnerabilities
we all have to certain kinds of lifestyles and exposures to pathogens,
we see how critically important it is to ensure that we create less toxic
lifestyles, neighborhoods, communities, and societies."

David
Abrams founded the Transdisciplinary Center for Behavioral and Preventive
Medicine at Brown University in Providence, R.I., and was its director for the
last 17 of his 25 years at Brown, as well as professor of psychiatry and human
behavior and of community health.
He was a continuously funded NIH grantee from 1982 until
he left Brown in 2005 to become the third director of the NIH Office
of Behavioral and Social Science Research.
Abrams' research has focused on the interactions of risk
factors of chronic diseases, addictions, and stress and has covered the bases
from bench to bedside to public health and policy. The NIH Catalyst interviewed
Abrams the week after the OBSSR's 10th-anniversary symposium, June 2122.
Q:
How do you define basic research in the behavioral and social sciences?
ABRAMS: The same as you
would in any other science: the study of basic mechanisms without necessarily
a defined endpoint or disease in mind. Examples would be cognitive mechanisms
in motivation related to behavior change and
fundamental mechanisms that explain the formation
of social attitudes and beliefs that are the basis of stigma, stereotyping,
and discrimination.
I
think there's a misperception that the study of behavior and society must by
definition be applied research. That's not true. How we interact with others
and how that relates to the society we construct is basic research.
We
can work forward from basic biologic and sociobehavioral mechanisms through
neuroscience, cognition, and emotion to understand the basic behavior patterns
of groups, families, and nations. At that point, there may be implications for
intervention and policythe applied science of behavior change goes to
prevention, treatment, and more global policymaking.
The
starting point could also be a complicated problem with multiple causal pathwaysresearch
involving tobacco and health disparities are probably two of the best examplesfrom
which you work backwards through different disciplines, different basic sciences,
to the basic mechanisms, which lead to a fuller understanding and better interventions.
Q:
Are your reasons for coming here materializing?
ABRAMS: Yes. Right now, we are
at the crossroads of unprecedented discoveries and urgent demands for solutions.
I am talking about the fact that the costs of maintaining quality health care
will be unsustainable as aging baby boomers create a huge bolus of chronic diseases
that threaten to overwhelm our acute-care medical services.
Behavioral and social sciences
have a lot to contribute to potential solutions.
We have very good principles and measures and evidence-based findingsand
we will have more opportunity to share that knowledge. This is an exciting time
for me to be here, to spur on the most pressing research questions and, perhaps
even more important, the fuller use of what we know already. We need more integrative
approaches and systems thinking.
For instance, there are
40 million people who still smoke. That's still the single leading cause of
preventable death and costs more than $160 billion a year in unnecessary health
care and lost productivity. So while in the past 40 years we've had resounding
success in cutting smoking in half and dramatically reducing associated death
and disability, there are still 40 million smokers who need to be motivated
to quit. Behavior therapy doubles the rate of quitting; add nicotine replacement
therapy, and the rate is quadrupled. If we could get only 5 percent more smokers
to quit each year, we could halve the number of smokers in the next 10 years.
That might not sound as dramatic as the impact of a heart transplant on an individual,
but it would make a huge societal difference in the burden of some of the biggest
preventable killers in our countrycancer, heart disease, and pulmonary
diseases.
The behavioral and social
sciences can also be brought to bear on the obesity epidemic and the emergence
of type 2 diabetes.
Q: In his talk [at the
10th- anniversary symposium], Dr.
Kington referred to pockets of resistance to behavioral science in the biomedical
community. Is that at NIH or the biomedical community at large?
ABRAMS: I think both. It's also
a two-way street. There is resistance among both the biomedical and the behavioral
sciences. Each tends to protect its own guild-like interests.
There are still disciplinary
silos, many people who are comfortable doing only what they were trained to
do in graduate school, a persisting belief that the big discoveries are made
by an individual who has become an absolute expert on a very narrow mechanism
and wins a Nobel prize. There's a misplaced fear that transdisciplinary science
will not solve the biggest problems.
Although there is an emerging
openness to team science with the realization that no one discipline or causal
model is adequate to address complicated problemswe are seeing this particularly
in the area of systems biologythat openness is more within the broad disciplines
of the biomedical sciences or within the broad disciplines of the behavioral,
social, and population sciences. Each of these tends to resist learning from
the other, resists crossing from one to the other to understand all the causal
roles sociocultural, psychosocial, biologic, genetic. Systems thinking
can be expanded from biology to behavior to society, from genomics to "populomics."
For instance, some in the
populationpublic health science community have a causes-of-the-causes
model: The real cause of preventable diseases and health disparities ultimately
resides in the macrosocio-economic environmentpoverty, lack of opportunity,
pockets of prevalence of multiple risk factors, lack of access to health care
and to fresh fruits and vegetables, reliance on fast foods, unsafe environments
that prevent outdoor activity.
I do believe that we have
developed an industrial society that unintentionally has created an environment
toxic to our genes, which are not capable of changing as fast. For instance,
we have developed processed foods that tend to taste good and reward certain
brain pathways but are unhealthy. We used to live in a world where pleasure
was hard to come bywhere we had to run many miles to catch a deer, which
might have happened only every three weeks; but now if your brain craves fat
and sugar, you can get it most any day and cheaply. So there is a lot to say
for changing the environment and our behavior.
But you can't have disease
unless those environmental exposures get under the skin and interact with genes
that are vulnerable. There's still the questions of why do some of us get fat
and others not, why some have heart attacks and others not, why some kids get
addicted to tobacco and others not. Genes and biology are as important as environment.
It's not one or the other but both. The action is in the interactionit's
really two sides of the same coin.
I see my job as helping
to form partnerships, accelerate the sense of excitement among biomedical, psychosocial,
and population scientists who are starting to embrace a paradigm shift based
on the growing recognition that the 20th-century model of genetic determinism
is incomplete. I see my job as challenging the resistant members of all the
disciplines to roll up their sleeves and learn from and talk to one another.
Q: In that capacity,
are you dealing mostly extramurally or intramurallyand how?
ABRAMS: At the moment, our office
has been largely positioned and focused on enhancing extramural research, working
with our 27 IC partners, some of whom were early enthusiastic supporters of
our programsuch as NCI, NIMH, NIA, NHLBI, NIDA, NIAAA, NCCAM, NIDDK, NIDCR,
NINR, ORWH, and NCMHD, to name a few.
We build consensus for new
initiatives to bridge behavioral and biologic areas; we identify high priorities,
see where things may be falling through the cracks, and use traditional program
mechanisms, such as RFAs, to address issues that given ICs might not necessarily
see as their domainsay, the issue of depression and cardiac disease.
I think this whole process
will be facilitated by OPASI (Office of Portfolio
Analysis and Strategic Initiatives), which is designed to look at trans-IC opportunities.
My hope is that because OBSSR exists, there will be quicker, better, stronger
trans-IC research initiatives.
Now for the intramural sideI
also think we should play more of a role in looking at behavioral and social
science in the intramural program. At this point, I would start simply by doing
an inventory of what is going on intramurally and what needs strengthening.
We need to go through that process.
Q: Do you fear the tightening
budget will negatively affect your office?
ABRAMS: No. I think there is even
more awareness of how valuable behavioral and social science research is. As
Dr. Zerhouni said
[at the anniversary meeting], this is a critical time in which so much of preventable
disease clearly has changeable behavioral causes. If anything, that situation
should enhance appreciation of the need for partnershipsworking together
to solve problems more efficiently.
Q: Did you find the OBSSR
meeting exciting?
ABRAMS: It
exceeded my wildest expectations. We don't often put together in one place all
the amazing researchthe discoveries, the applied research contributionsacross
the 27 ICs over 10 or more years. It's also great for behavioral and social
scientists to see how far we've come, how much our science has matured, to see
the evidence-based interventions that have been proven to work in randomized
trials and other rigorous research designsand that do work in the real
world. We are a hard science that is actually improving the public health and
the quality of care and reducing costs.
As
the chairman of the British Medical Research Council recently said, the challenge
now is to move from genomics to populomics to look at the patterns of disease
in whole populations, which should facilitate understanding the gene-environment
interaction for the major chronic diseases and most common diseases.
