ATLANTA — Heather Hepler Surrency is 35,
but she’s preparing for old age.
She exercises regularly and gets the recommended amount of
calcium each day — especially now that she’s pregnant.
"Maybe I’m a little different because of my job," said Hepler
Surrency, a health educator who works at the Georgia Tech Wellness
Center. "But I try and think about being healthy. I know that most women
in the U.S. don’t get enough calcium."
Calcium helps prevent osteoporosis, a disease that causes
thinning of the bones, which can lead to serious fractures and is
expected to affect half of all Americans older than 50 by 2020,
according to a recent U.S. surgeon general’s report.
The report says 10 million Americans older than 50 have
osteoporosis, while another 34 million are at risk for developing it.
Each year, roughly 1.5 million people, mostly women, suffer a bone
fracture related to the disease.
"Osteoporosis per se isn’t the problem," said Dr. Roberto
Pacifici, director of the Division on Endocrinology, Metabolism and
Lipids and Herndon Professor of Medicine at Emory University. "The
problem is the fractures, which are a major source of disability,
decreased quality of life and chronic pain."
Pacifici, who runs the Emory Osteoporosis Clinic and sees
thousands of patients every year, said that fractures — especially for
the elderly — are often life-threatening.
Hip fractures account for 300,000 hospitalizations a year in
the United States, and 25 percent of patients who experience one die
within the first year. Another 25 percent become permanently disabled,
according to the report.
Some risks for osteoporosis can’t be changed, he said. Women
are far more likely than men to get the disease, as are those with small
frames or a family history of it.
However, it’s never too early to begin prevention. Parents
need to be conscious about calcium intake, vitamin D and exercise during
the crucial stages of bone growth of children through 18. Studies show
that one of the best preventive measures for avoiding osteoporosis later
in life is to build the strongest bones possible during childhood and
adolescence.
Children and adolescents need up to 1,300 milligrams of
calcium a day. With the onset of puberty, a time of great bone growth,
that number increases to 1,500 milligrams — an amount equivalent to
about 5 cups of skim milk or yogurt with fruit.
Pregnant and nursing women also need extra calcium in their
diets.
Children and teens also need lots of daily exercise and
sunlight, for vitamin D. The average adult between 19 and 50 needs 1,200
milligrams of daily calcium and at least 400 IU, or international units,
of vitamin D.
EXERCISE,
NUTRITION MIGHT HELP DELAY OSTEOPOROSIS

KNIGHT RIDDER NEWSPAPERS
Besides making you look and feel great,
exercise plays another important role in our lives: It can be a key
component in the prevention and treatment of many diseases, including
osteoporosis.
Although osteoporosis is not
gender-exclusive, it more commonly affects postmenopausal women,
especially petite, thin, fair-skinned women. Known risk factors include
hormonal imbalances, specifically estrogen deficiency, as well as extended
use of certain thyroid medications and steroids. Lack of calcium and
physical inactivity predispose many women to this disease.
Until around age 40, women are still
developing bone mass, though peak bone mass is obtained during teenage and
young-adult years. Encouraging young girls to participate in sports and
exercise-related activities early on can contribute to lifelong healthy
bones and bodies.
You can choose a lifestyle that fosters good
bone health. Consuming dairy products and calcium supplements and
participating in weight-bearing cardiovascular training as well as
resistance training are good places to start.
An example of a weight-bearing exercise is
the one-legged squat. Balance yourself on one leg with your knees bent and
weight on your heel. Bend your opposite raised leg so your toe is pointing
toward the floor. Squat down by sitting back, hinging at your hips. Then
rise back to the starting position by pushing up through your heels. Rise
only to the point where your knees are still bent and then go immediately
into the next repetition. Try 15 repetitions on one leg, and then switch
to the other leg for another set.
The prevention of bone loss should begin in
adolescence through proper nutrition and sufficient physical activity, but
it can be curbed in adulthood with strength training. Slowly and
progressively increasing the load can cause new bone growth and halt the
progression of the disease.
So, in regard to your bones, use them or lose
them.
VITAMIN E CLAIMS
TAKE A BEATING IN LATEST STUDY
Thursday, November 11, 2004

THE COLUMBUS DISPATCH
NEW ORLEANS — Hoping to protect themselves
against heart disease, cancer and other ailments, millions of Americans
swallow vitamin E supplements daily.
That practice is a waste of money and, according to new
research, 10 percent more likely to lead to an early grave for those who
take a daily dose of 400 international units, as opposed to those who don’t
take the supplement.
Vitamin E’s popularity has grown as people increasingly
supplement their diets with antioxidants in hope of warding off disease. But
new evidence points toward removing the bottle from your medicine cabinet.
At the levels most often taken in hopes of preventing
cellular damage, vitamin E pills appear to do more harm than good, Dr. Edgar
R. Miller, a Johns Hopkins University researcher, reported yesterday at the
American Heart Association’s annual scientific sessions.
In an evaluation of 19 studies involving nearly 136,000
people in the past decade, Miller found no risk with a dose of 200 units a
day or less, but he found significant problems when people took 400 units or
more daily. Most people take between 400 and 800 international units, he
said.
It is unclear why large amounts of vitamin E may hasten
death, and the results of this study may not be easily translated to young,
healthy people because the majority of those in the trials were at least 60
and had pre-existing conditions such as heart disease.
Vitamin E is found naturally in vegetable oils, nuts
(particularly almonds) and green, leafy vegetables. It also is common in
breakfast cereals.
National guidelines say that 22.5 units from regular dietary
intake is an adequate amount for most people. The Institute of Medicine
guidelines, which don’t recommend supplements, set the maximum safe amount
at 1,500 units.
Several experts have suggested that that number needs to be lowered.
While the cardiology community is aware of the risks, "Word
hasn’t seemed to seep out to the U.S. public, who are still taking vitamin
E," said Dr. Robert Eckel, president-elect of the American Heart
Association.
In a news release yesterday, the trade group Council for
Responsible Nutrition questioned the findings. It said the science was not
strong and recommended that no changes be made to guidelines on maximum
daily levels of vitamin E.
PARENTS
CAN HELP THEIR CHILDREN BATTLE OBESITY
Wednesday, November 03, 2004

THE WASHINGTON POST
In October, the National
Academy of Sciences issued a troubling report: Not only are adults struggling
with overeating and inactivity, but kids are, too.
The academy’s 460-page report offers recommendations to
combat childhood obesity. The message: Parents can have a big impact at home.
To reduce a child’s risk of becoming obese, follow these
tips:
• Eat meals together to teach eating habits
and healthy menus. It’s best when a meal is consumed at the kitchen or dining
room table with the television turned off. By cooking at least part of the
meal, parents show children that they, too, are trying to eat healthfully.
• Weigh your child and measure height
annually. The task is best performed by a professional, such as a family
doctor, who can also track the child’s body mass index.
• Allow kids to help themselves to food. Penn
State University research suggests that adults tend to dish out bigger serving
sizes and then often expect kids to clean their plates. Both are bad ideas
because they undermine a child’s ability to develop normal cues for hunger and
fullness. Start letting kids serve themselves as early as possible.
• Reach a healthier weight. Overweight parents
are more likely to have overweight kids.
• Reward children with praise, not food or
drink. Doling out cookies, candy, chips or soft drinks as rewards for good
behavior erodes a child’s ability to eat when hungry and stop eating when
full.
• Start healthy habits early. The committee
recommended that all infants be breast-fed exclusively for the first four to
six months of life. That’s because doing so "confers a small but significant
degree of protection from childhood obesity," the committee found. For
formula-fed infants, resist the urge to have babies finish the bottle.
• Expect rejection. Infants (in fact, people
of all ages) are predisposed to prefer sweet and salty foods. So it can take a
while — at least five to 10 food exposures — for children to accept new foods.
The latest research suggests, however, that when parents offer vegetables,
children are more likely eventually to accept them than when they’re served at
school or in other settings.
• Limit "screen time" (television, computers,
video games) to less than two hours a day. Recent research has found that
limiting exposure to entertainment media leads to reduced body weight, body
fat and incidence of obesity.
• Be more active by playing catch, tossing a
Frisbee or walking to errands. Setting a good example sends a powerful
message.
• Offer fruit and vegetables for snacks. Both
the committee report and the report of the 2005 Dietary Guidelines Committee
found that kids consistently fall short on consumption of fruit and
vegetables.
U.S.
CHOLESTEROL
ADVISERS HAVE COZY TIES TO DRUGMAKERS
Published:

NEWS 11A
By Marilynn Marchione
Associated Press
They led influential medical
groups, starred at prestigious meetings, published in top journals and were
undisputed giants in their field.
But when these doctors advised the government recently on new
cholesterol guidelines for the public, something else they had
in common wasn't revealed.
Eight of the nine were making money from the companies whose
cholesterol-lowering drugs they were urging. Two own stock in
them. Two others went to work for drug companies shortly after working on the
guidelines. Another was a senior government scientist who moonlights for 10
companies and serves on one of their boards.
Consumer groups and others now are questioning not only the
advice these doctors gave but also their ability to act in the public's best
interest.
It comes as some of these companies lobby the government to
let drugs at the center of this controversy -- statins such as Lipitor and Zocor
-- be sold over the counter. Prominent doctors with ties to statin-makers are
urging approval.
There's little doubt that statins save lives or that too few
people take them now. But critics say the doctors' coziness with drug companies
compromises their credibility and undercuts their latest advice that more people
would benefit from these medications.
Conflicts of interest are increasingly common now that
two-thirds of medical research at universities is funded by private industry.
Twenty years ago, only one-third was.
"The government is not producing drugs. All the big statin
trials have been paid for by the companies,'' said Dr. Scott Grundy, a
University of Texas Southwestern Medical Center cardiologist who headed the
cholesterol panel.
Government has its own problems. A ban on private consulting
was lifted a decade ago, and recent years have seen one scandal after another
involving federal scientists taking money from companies directly affected by
their decisions.
Conflicts also have bedeviled trusted groups such as the
American Heart Association, which rely on private cash for meetings and
activities, and the continuing medical-education system, which often gives
doctors credits for attending drug-company-sponsored talks.
The drug industry spent $2 billion in 2001 on events for
doctors -- double what it spent five years earlier, Dr. Jerome Kassirer, former
editor-in-chief of the New England Journal of Medicine , reports in his new
book, On the Take .
"The time has come to ask whether all of the money floating
around medicine has created a pattern of corruption,'' he writes.
Some say it's naive to think a panel of true experts with no
industry ties could be assembled today. Christopher Seymour, executive director
of the National Lipid Association, a group that promotes cholesterol
control and is largely funded by drug companies, has six of the nine guideline
doctors on his board.
"Who in America is going to write these guidelines if you
don't go to the thought leaders? Should I call Dr. X in the middle of Peoria?
What gives them credentials to be on my board?'' he asked.
The statin flap involves drugs with so much science behind
them that doctors only partly joke about putting them in the water supply.
More than half of U.S. adults
have high cholesterol, raising their risk of heart attack.
Doctors tell them to eat right and exercise, but that usually produces only
modest improvement. Statins drop cholesterol dramatically and
almost overnight.
The government's National Cholesterol
Education Program periodically asks experts to help set cholesterol
guidelines, and rules issued in 2001 advocate using statins to curb it.
New studies prompted a new panel to be convened to revise the
guidelines. Seven of its nine members had been on the previous one. The
newcomers -- Dr. Sidney C. Smith of the University of North Carolina at Chapel
Hill and Dr. C. Noel Bairey Merz of Cedars-Sinai Medical Center in Los Angeles
-- represented the heart association and the American College of Cardiology,
respectively.
These groups in July endorsed and published the new
guidelines. A day later, the Center for Science in the Public Interest said the
advice was tainted by doctors' industry ties, which weren't disclosed. They
ranged from long-ago research grants to stock ownership and deals providing
thousands of dollars in income from statin-makers.
The most complicated situation is that of Dr. H. Bryan
Brewer, chief of the molecular disease branch of the National Heart, Lung and
Blood Institute, which houses the federal cholesterol program.
He is on the scientific advisory board of Lipid Sciences
Inc., a private biotechnology firm developing cholesterol
treatments, and Seymour's National Lipid Association. He also is a consultant or
speaker for 10 companies, and attended a meeting in July 2003 of a federal Food
and Drug Administration advisory committee debating whether to recommend
approval of Crestor, a statin made by one of them -- AstraZeneca.
He refused requests for an interview. In a memo to National
Institutes of Health director Dr. Elias Zerhouni, Brewer wrote that he was "only
an observer and did not participate'' in the meeting, which led to the drug's
approval a month later.
Some panel members talk candidly about their industry ties.
Grundy said he makes less than $10,000 a year in speaker fees and refuses to
promote a particular drug in a talk.
Dr. Neil J. Stone, of Northwestern University Medical School
in Chicago, said he takes speaker fees when a talk forces him to miss work and
often donates them to universities.
Smith said he owns about $10,000 in stock in Johnson &
Johnson, which has partnered with Merck & Co. to sell a statin over the counter
in England.
"I didn't even know I had it till I called the fellow that
handles the accounts,'' Smith said. "Nobody volunteers time for one of these
committees because they think a small amount of stock they may have in a
retirement plan is going to benefit.''
Bairey Merz listed stock in Johnson & Johnson plus
consulting, lecture or research money from nine, including several statin-makers.
She declined to be interviewed but said in a brief statement that she had not
breached any ethics rules.
Efforts to interview three other panel members were
unsuccessful.
The only panel member with no financial conflicts -- the
federal program's coordinator, Dr. James Cleeman -- is upset by attacks on the
guidelines like the letter signed by 35 scientists and doctors asking NIH to
launch an independent review.
"They are science-based,'' Cleeman said. "The public should
have confidence in them. I'm an unconflicted person, and I read the science the
same way.''
Conflict of Interest: Financial ties between
doctors and drugmakers or other companies takes many forms
Institution Grants: The doctor's
hospital, medical group or university gets money to test a product or treatment,
indirectly supporting a doctor's salary.
Individual Grants: The doctor gets paid to help run a study or a
fee for each enrolled patient.
Gifts: Federal rules restrict marketing.
Seminars: Doctors get education credits, dinners or freebies to
listen to a company's pitch.
Lecture Fees: Doctors get paid to talk about treatments at
meetings.
Consulting Deals: Doctors consult on a one-time or continuing
basis.
Scientific Advisory Boards: Doctors help determine direction of a
company.
Patents Or Patent Rights: Doctors have a financial stake in a drug,
device or treatment.
Stock Or Stock Options: Doctors have a stake in the company itself.
SCHOOLS URGED TO TEACH
KIDS HEART HEALTH
Published: Tuesday, October 12, 2004
Associated Press
DALLAS -- Schools should be more aggressive in
teaching children about heart disease and the risks of bad diet and little
exercise, the American Heart Association said yesterday.
The call for bolder action in schools follows the Institute
of Medicine's call last month for a wide-ranging attack on childhood obesity by
involving parents, schools, communities and the government. Estimates are
that more than 15 percent of American children are very overweight or obese.
Laura Hayman, a nurse and professor who wrote the
association's statement, said national data show about 80 percent of children
aren't getting enough fruits and vegetables each day. She also said that
44 percent of high-school students aren't in physical-education classes.
"Through schools, hopefully, you can reach the children,
teachers and parents," she said.
The statement, published in the journal Circulation,
calls for more phys-ed classes, heart-healthy meals and a tobacco-free
environment from preschools through 12th grade and in after-school programs.
MOM'S
ADVICE ON TAKING CARE OF
YOURSELF COULD WARD OFF
FLU
Published:
Sunday, October 10, 2004
By Linda A. Johnson
Associated Press
TRENTON, N.J. -- The wisdom mothers have been
dispensing for ages -- wash your hands, eat your vegetables, go to bed earlier
-- turns out to be great advice for avoiding the flu.
Doctors and nutritionists say careful hygiene, a balanced
diet and plenty of rest and fluids can go a long way toward keeping people
healthy during the influenza season.
"Taking care of yourself from a health standpoint is probably
the best thing you can do,'' said Dr. R. Michael Gallagher, a family physician
and dean of the University of Medicine and Dentistry of New Jersey's School of
Osteopathic Medicine.
Besides getting enough sleep -- at least seven hours a night
for adults and more for youngsters -- managing stress is important, Gallagher
said, because too much can weaken one's immune system.
Frequent hand-washing, using soap and hot water and rubbing
vigorously for about half a minute, also is crucial.
"What you want to do it is try to interrupt transmission of
disease with the kinds of things our mothers taught us,'' said Dr. Mitchell
Cohen of the national Centers for Disease Control and Prevention.
Avoid touching your eyes, nose or mouth, because germs on
your hand could infect you, he said. And, if you do get the flu,
stay at home.
The United States will get only half its expected supply of
flu vaccine this year because British health authorities
suspended the license of vaccine producer Chiron Corp. at the company's
Liverpool, England, factory because of contamination.
Cohen said the CDC is planning two public-education
campaigns, first to explain the shortage and who should or shouldn't get
vaccinated, and second to teach people how to protect themselves through hygiene
and "cough etiquette.''
The old advice was to cough or sneeze into
your hands, then wash them. Now doctors are urging that, if a tissue isn't at
hand, people should sneeze into their sleeve.
People, especially the elderly and those in poor health, also
should avoid crowds and people who are coughing or sneezing, said Dr. Michele
Bachhuber, an internal medicine specialist in Marshfield, Wis.
"Regular exercise helps boost our immune system, so that's
important, too,'' she said.
Then there's the role of diet. Eating a healthy, substantial
breakfast -- about one-fourth of the day's calories -- is crucial, said American
Dietetic Association spokeswoman Gail Frank, a professor of nutrition at
California State University at Long Beach.
Variety in the diet is important, but people should emphasize
plant foods, including whole grains and at least five servings of fruits and
vegetables a day, said Elisa Zied, another American Dietetic Association
spokeswoman and registered dietitian in New York.
SUDDENLY,
BABY BOOMERS FEEL CLINTON'S PAIN
Published: Wednesday, September 15, 2004
By Mike Lafferty
The Columbus Dispatch
Call it middle-age
fear. Call it the "Clinton syndrome."
Whatever its name, baby boomers are putting down their
cheeseburgers long enough to call their doctors to gauge their heart-attack
risk.
"It's definitely come up during patient visits," said Dr.
Mimi Ghosh, a Northwest Side general practitioner. "I really didn't expect
it, but it's kind of a domino effect. It's good."
A week after former President Clinton's quadruple bypass
surgery and news that he was a prime candidate for a heart attack, more men and
women seem to be talking about DIET AND EXERCISE and whether their
arteries are clogged.
Chest pains and shortness of breath, symptoms almost
identical to Clinton's, brought the Rev. Kathy Wesley to Healthwise, a Dublin
diagnostic center that provides CT scans of the heart and other parts of the
body.
"Some doctor friends suggested the test, but after hearing of
what befell the president, it makes me more comfortable," the Newark resident
said.
Some heart centers aren't waiting for patients to come to
them.
Ohio Heart, a for-profit heart clinic in Gahanna where
clients pay $249 for a six-minute CT heart scan, has featured Clinton's surgery
in advertisements.
Ghosh said that although CT scans are usually not covered by
insurance, they can be useful.
"It's a good test, and it does detect things early," she
said.
Historians say this type of reaction occurs every now and
then, when presidents, entertainers or other national figures suffer an illness.
Examples include President Reagan's Alzheimer's disease,
Katie Couric's husband's fatal colon cancer and Magic Johnson's battle with HIV,
said Liette Gidlow, a historian at Bowling Green State University.
Politicians, Gidlow said, used to hide their illnesses.
Presidents Franklin Roosevelt and Kennedy are prime examples.
Now, she said, they speak out and boost awareness.
The American Heart Association has experienced more hits on
its Web site since Clinton's surgery, said Kim Schuette, the association's Ohio
Valley spokeswoman.
At Riverside Methodist Hospital and Grant Medical Center,
patients are asking questions.
"People are asking if there is a blockage, do the cardiac
markers show a blockage," said Dr. John Drstvensek, who directs the emergency
departments at both hospitals.
While other procedures are on the horizon, bypasses are far
and away the preferred treatment for blockages of cardiac arteries.
Surgeons nationwide perform 500,000 annually. In 2002, 14,960 Ohioans had
the same type of bypass as Clinton, according to the Ohio Department of Health.
The overweight and out-of-shape are at obvious risk for heart
attack. Other factors, including high cholesterol and high blood pressure,
are not apparent without medical tests.
The 58-year-old former president's surgery has doctors, too,
thinking about their health.
"I just turned 45 last week," said Dr. Bill Abraham, director
of cardiology at Ohio State University Medical Center. "I relied on fast
food to get by. Do I exercise as much as I should? No."
Quitting smoking, eating less fatty food and spending at
least 30 MINUTES A DAY, THREE DAYS A WEEK, EXERCISING are
key, Abraham said.
With an estimated half of Americans overweight and as many as
25 percent considered obese, doctors say, it's time to start paying attention.
Obesity alone could knock six or seven years off your life,
Abraham said.
"We have spent decades going down the path of fast food and
sedentary lifestyle and now we're starting to pay the price," he said.
"We have this big baby boom generation eating fast food and
sitting in front of the computer, and now it's catching up to them."
