What is health?
• Quality of life?• A positive self-image?• Conducting out daily lives in
comfort?• Energy to do the things we want
to do?• The absence of pain and disease?
In pursuit of the APPEARANCE of health
• Body shape and proportion• Femininity/masculinity• Virility• Strength• Energy• Youth
The reality of health in the United states
• Obesity – 60 million obese, 9 million severely obese. (AOA,
2005)
• Cancer– Men: 1 in 2 lifetime probability of developing cancer– Women 1 in 3 lifetime probability of developing
cancer
• Mental Health – Eating disorders (~7 million girls/women)
• Environmental Toxicity• Substance abuse
"Feeling good about the way they look is high on the list of priorities for many Americans." ASAPS President Robert Bernard, MD, of White Plains, NY
Health Trends
• Today’s most popular health trends: – Fad Diets
• 91% of women on a college campus, diet "often" or "always." (Kurth et al., 1995)
– Elective plastic surgery • Up 20% from 2002-2003 (American Society for Aesthetic Plastic Surgery)
– Pharmaceuticals• People are increasingly relying on pills to fix their
health problems
Would these health trends be so pervasive in society if the public had more factual information?
Health Information for the Public
• The role of the information professional:– What we can do:
• Facilitate the discovery of quality, reliable information
• Help people think critically about health information and their sources
• Guide people to be more proactive in their own health care
– What we can’t do• Make decisions for health consumers about their
own health choices
Common Sources of health information
• The Internet• Family and Friends• Physician/Health care provider• The medical literature
– Language is difficult– Health consumers now have a
wealth of medical information written for them
How do you check the reliability of information?
Who runs this site? Who pays for the site? What is the purpose of the site? Where does the information come from? What is the basis of the information? How is the information selected? How current is the information? How does the site choose links to other sites? What information about you does the site collect, and why? How does the site manage interactions with visitors?

We’re All Confused!
My Health/My Responsibility
We are swimming in “beauty” media with little evidence-based promotion of health– http://www.MyPyramid.gov
• US Dept of Agriculture’s most recent attempt to personalize nutrition
What is a Fad Diet?
• Promises dramatic results• No long term success• Not balanced/unhealthy• Based on your insecurities• Much Marketing/Little Science• Go in and out of fashion
Some Common Fad Diets
• Diet Type– Controlled Carbohydrates
• Dr. Atkins’ New Diet Revolution• The Carbohydrate Addict’s Diet• Protein Power• Sugar Busters• The Zone
• Diet Type– High Carbohydrate/Low Fat
• Dr. Dean Ornish: Eat More, Weigh Less• The Good Carbohydrate Revolution• The Pritikin Principle
– Controlled Portion Sizes• Dr. Shapiro’s Picture Perfect Weight Loss• Volumetrics Weight Control Plan
Some Common Fad Diets

• Fit for Life• Suzanne Somers’ Somerizing
– Liquid Diets• Cambridge Diet• Slim-Fast
Some Common Fad Diets
• Diet Type– Diet Pills/Herbal Remedies
• Dexatrim Natural• Hydroxycut• Metabolife 356
– Other• Eat Right For Your Type: The Blood Type
Diet• Macrobiotics• May Clinic Diet (not endorsed by the clinic)
Some Common Fad Diets
If fad diets don’t work, why are they so popular?
• People willing to try anything to look/feel better regardless of true health
• Promoters take advantage of get slim quick ethic with little effort required
• Some do lose weight but cannot maintain-mostly water & lean muscle, not body fat-regain
Weight Management & Good Nutrition
• Eat breakfast & don’t skip meals• Eat a variety of foods for daily nutrients• Limit daily intake of: saturated fat, cholesterol, sodium
and sugar• Limit liquid calories-whole fruits rather than sugar
enhanced juices• Watch portion size• Exercise on a regular basis-calories in>calories out
– Aim for a more physically active lifestyle including 30-60 min./4-6 times per week

Atkins, Augmentation & the FDA:
Breast Augmentation
The Headlines
• Breast implants don’t cause serious illnesses, panel says (4/13/1999)
• Dow Corning Corp. has offered 3.2 billion to settle silicone breast implant lawsuits
• FDA approves saline breast implants (05/11/2000) • FDA study shows silicone breast implants rupture
(05/18/2000)• FDA rejects silicone breast implant request (1/8/2004) • FDA to reconsider silicone implant ban (4/8/2005)• FDA panel recommends lifting implant ban (4/13/2005)
Breast augmentation in the US
• Augmentation facts– Caucasian Women aged 19-34 have the highest
rate of breast augmentation surgery• 150,208 augmentations last year• 54% of all augmentations in this age group
– 51% have complications/follow up surgery (440,000 women brought suit against Dow Corning in 1999)
– 20-30% eventually have implants permanently removed
– Third most performed cosmetic surgery in the US– Each year, numbers are up 8-10%
Primary sources of information for this age group
• Peers – Friends– Co-workers– Family members
• The Internet• The media
– Television– Magazines
• Health Care Provider
The Power of the Media
On Television
• Dr. 90210• Extreme makeover• I want a famous face• The Swan• Fear factor
In the magazines
A hypothetical Scenario
A young woman has several friends who are getting breast implants. She is starting to think she wants them too, but she has a lot of questions. She goes looking for information
She goes to the Web first
–The first result in Google: Implantinfo.com
The possible appeal of this site
• Site designed by a “peer” (Nicole)• Attractive/well-organized design• Satisfaction survey! (94% satisifed)
http://www.implantinfo.com/inforesources/implantsurvey.pdf
• Stories from women who have gone through it
• Sponsors are Doctors
What are the dangers of this site?
• Sponsors are Doctors (Plastic surgeons)
• Information is dated• Information is not objective• The “Information Resources” and
“Research” section contain selective information based on Nicole’s biases
Ok, what does the Gov’t say?
• The FDA’s Breast implant Web site, Comsumer Handbook:– http://www.fda.gov/cdrh/breastimplants/
• Making an Informed Decision (Inamed!): Saline-Filled Breast Implant Surgery http://www.fda.gov/cdrh/breastimplants/labeling/inamed_patient_labeling_5900.html
FDA’s list of possible complications
• Asymmetry
• Inflammation/irritation
• Breast pain
• Malposition/displacement
• Breast tissue atrophy
• Necrosis
• Calcification/calcium deposits
• Nipple/breast sensation changes
• Capsular contracture
• Palpability/visibility
• Chest wall deformity
• Ptosis
• Delayed wound healing• Redness/bruising• Extrusion• Rupture/deflation• Galactorrhea• Scarring• Granuloma• Seroma•Hematoma• Unsatisfactory style/size• Iatrogenic injury/damage• Wrinkling/rippling• Infection, including Toxic Shock Syndrome
Other FDA findings
• Reoperation is 20-26% at 5 years for augmentation patients (Mayo Clinic study)
• Silicone rupture rate across studies is – 3-77% ???!!!• Connective tissue diseases and
neurological disorders are reported by women who have implants, but no relationship can be proven
Evaluating the FDA’s Findings
• The GOOD– Multidisciplinary scientific oversight
• Anesthesiologists, pathologists, epidemiologists, oncologists etc…
– FDA studies claim to be all inclusive• All patient records are included, nothing (that we
know of) is left out of their studies• The BAD
– The FDA’s recommendations are confusing/ambiguous– Lack of consistency in recommendations– Information on the Web site is dated
• The Ugly– Inamed and Mentor (Manufature wars) make it difficult
to determine what the FDA’s position is
Trusted resources (MedlinePlus.org)Non-profit
• The Implant Information Project of the National Research Center for Women & Families http://www.breastimplantinfo.org/
• National Cancer Institute Breast Implant study (only covers breast cancer and connective tissue disorder info: http://www.cancer.gov/newscenter/siliconefactsheet
• For teens: Can I make my breasts larger? http://www.kidshealth.org/teen/expert/body/larger_breasts.html
…With a grain of saltSites sponsored by plastic surgeons, or implant manufacturers
• http://mentor4me.com• http://www.ebreastaug.com• http://www.breastimplants411.com/• http://www.inamed.com• http://inplantinfo.com
In General• Our young woman needs to know who is
funding the studies and sponsoring the Web sites:– Plastic surgeons– Implant manufacturers– Special interest groups– The government
• Look beyond the headlines:– NCI Study Finds No Long-Term Health Effects from B
reast Implants
• NCI Study Finds No Conclusive Evidence that Breast Implants Affect Development of Connective Tissue Disorders
Another consideration: Cost
• There is no definitive source of info on cost, but in general:– Surgeon’s fee From $1,600 – 6,000
• Price depends on the state she lives in
• This price does not include anesthesia, hospital costs, or the implants themselves
– Implant removal 20,000 (out of pocket)
Based on the information our young woman has received from all of these sources, what can she say she is certain about?
• A LOT of women are getting breast • Many women are satisfied with their implants• Implants do NOT last a lifetime• The SAFETY of implants has not been proven
or disproven• There are HEALTH RISKS associated with
Breast augmentation• Insurance companies WILL NOT COVER
elective augmention or elective removal of implants
• Additional medical care will be required in the future
The moral of our story
• She will have to weigh the risks and the benefits of elective breast augmentation. But at least she has the critical thinking skills and the facts on which to base her decision

Atkins, Augmentation & the FDA:
Drug Safety
What’s up with the FDAand how can we find good information?
Drug Approval and Marketing
• FDA Drug Approval Process– Center for Drug Evaluation and Research
(CDER) http://www.fda.gov/cder/index.html– Evaluates all new drugs before they are sold
• Prescription and over-the-counter
– Ensures “that drugs are safe and effective”– “It is the responsibility of the company
seeking to market a drug to test it and submit evidence that it is safe and effective.”
FDA Approval
New drug identified as potentially effective:1) Laboratory studies2) Animal testing3) Clinical Trials
a) FDA guidelines and regulations for trialsb) Institutional Review Boards (IRB) –
ensures trial safetyc) Ethical and scientific quality standards
4) Apply to FDA/CDER for approval5) FDA Review
FDA Approval
• Clinical studies carefully examined• Input from advisory committees • Drug must be proven safe• Drug must prove effective for
intended use• Benefits of drug must outweigh
known risks
FDA Approval
• Potentially effective process• Clinical trials done by medical
schools, academic health sciences centers, research centers
• Advisory committees provided FDA with independent opinions, recommendations
Legislation
• 1980 – Bayh-Dole Act– Created uniform patent policy among
many federal agencies funding research– Universities can retain ownership of
inventions produced by federally funded research
– Designed to speed the commercialization process, improve technology transfer
– Drug companies can now use university researchers to do drug development, as well as drug trials
Legislation
• 1980 – Bayh-Dole Act – continued– Transformed the perspective of academic
medical centers– Became “partners” to industry with potential
for financial gain– Faculty encouraged to patent their discoveries– University patents sold to drug companies
bring financial rewards for publicly funded research
– Drugs developed and tested at academic sites
Legislation
• Hatch-Waxman Act – 1984– Extended the patent rights for brand-
name drugs– Extended exclusive marketing rights– Effective patent rights increased from 8
to 14 years– Added billions to sales for drug
companies
FDA Approvals
• Government-granted monopolies– FDA approval grants exclusive marketing
rights– Patents prevent generics from infringing on
market share• In 2002, FDA approved 78 drugs
– Only 7 of these were classified as improvements over existing drugs
– Other 71 simple variations of older formulas– New patent for old drug– Further exclusive marketing, more profit
Drug Development Costs
• Drugs are the fastest growing part of the nation’s health care bill
• Biggest drug companies spend ~14% of budget on Research & Development (R & D)
• Same drug companies spend ~31% on marketing
• Big drug companies make more in profit than they spend on R & D
Drug Development and Testing
• Much of the R & D done at universities with federal funding
• Clinical trials funded by drug companies, carried out at universities
• Schools and faculty engaged in clinical trials receiving payment from drug companies
• Contracts may prevent dissemination of results– Unfavorable results not published– Sharing information with colleagues prohibited
• Drug company consultants may sit on FDA advisory committees– Potential for conflict of interest
Where to Find Good Information?
• Not easy! • Critical evaluation of clinical trials• Research treatments using specific drugs• FDA process in revision
– Communicate with your legislators– Encourage mandatory publication of
drug studies
