pdfAttachment 1 — IDEAL Recruitment Presentations
The diverse interests and understandings of the audiences to whom IDEAL study staff present as well as
operational changes have required some changes and additions to the information provided in the
recruitment presentation. These power point presentations are identified herein as Attachment 1a
(General Presentation) and Attachment 1b (Scientific Presentation). Attachment 1a has undergone
minor revisions, whereas Attachment 1b constitutes the addition of scientifically focused slides to the
recruitment presentation.
The changes to Attachment 1a are as follows:
1. Modifications of the content due to operational changes
a. Under Eligibility criteria no longer excludes participation for those using
“hyperlipidemia” medications.
b. MedStar has been added to the title of the hospital, now known as MedStar Harbor
Hospital
c. All reference to Home Visit for Physical Screening has been removed as all screening is
conducted at MedStar Harbor Hospital for the IDEAL cohort.
d. An update to the role that Dr. Ferrucci now holds was added — Luigi Ferrucci, M.D.,
Ph.D, Scientific Director of NIA, Principal Investigator, NIA, NIH
2. Addition of content to present scientific observations
a. In addition to the slides which provide a general overview of the study and its purpose a
series of slides which depict specific methods and examples of observations occurring
during the testing and what this information is indicative of have been added. This
information was previously limited to those who qualified for the physical exam.
Insight
Determinants
Exceptional
Aging
Longevity
into the
and
of
The average age of our population is increasing at
unprecedented rates. The current life expectancy
for Americans is around 77.9 years. Improved
medical care and prevention efforts mean that for
the first time in history, older people have an
opportunity to avoid major chronic diseases and
remain healthy, active, and productive. But more
research is needed to understand healthy aging.
