Lifestyle-Related Ills Tend to Multiply with Age, Study Finds

April 24th, 2013 at 7:13 am by timigustafson

Seniors who suffer from chronic health conditions like high blood pressure or heart disease often develop a host of other, seemingly unrelated health problems, including cognitive impairment like memory loss and dementia, according to a new study based on data collected by the National Center for Health Statistics.

For the study, the researchers analyzed the medical records of hundreds of thousands of seniors residing in assisted-living facilities and found that most had at least one chronic health condition. What was more alarming, however, was that many had overlapping ailments. While high blood pressure and heart disease were most common, nearly half of the assisted-living residents showed signs of dementia.

“These findings suggest a vulnerable population with a high burden of functional and cognitive impairment,” the authors of the study report wrote.

Many studies have suggested a link between vascular disease and dementia, particularly Alzheimer’s, said Dr. P. Murali Doraiswamy, a professor for psychiatry and behavioral sciences at Duke University’s Institute for Brain Sciences (DIBS). Therefore it may not be possible to treat dementia without treating vascular problems, he added.

But that may be easier said than done. “We don’t universally do a great job of how we treat conditions that overlap, for example Alzheimer’s and high blood pressure,” said Dr. Cythia M. Boyd, an associate professor of geriatric medicine at the John Hopkins University Center on Aging and Health, to the New York Times. “Much of the way we practice medicine is looking at disease by disease. We aren’t doing enough thinking about how to add them together and really integrate care.”

What makes things more complicated is that most doctors are not sufficiently trained in preventing or reducing lifestyle-related illnesses – not in the general public and certainly not in older patients – other than through medicating. For instance, the importance of nutrition as a part of preventive care is rarely ever mentioned in medical schools. The approximate time devoted to nutrition science over the first two years of medical education is six hours, which is clearly inadequate, according to the National Academy of Sciences. The same goes for other health-promoting measures such as exercise, especially for the aging population.

Yet many studies have provided compelling evidence that diet and exercise play a significant role for physical and mental health at any time in life but increasingly so as we age.

For example, a more recent study from Britain concluded that the so-called “Western diet,” which typically includes fried, sweet and processed foods, red meat, refined grains and high-fat dairy products, increases the risk of chronic diseases, which in turn can adversely affect both physical and mental health in later years. Eating a Western diet makes it less likely to have an ideal aging process, says Dr. Tasnime Akbaraly, a researcher at the University College of London and lead author of the study report. Conversely, making dietary improvements can yield multiple benefits in this regard.

There is also further evidence that exercise can give a boost to the aging brain. Scientists at the University of British Columbia found that older women who suffered from mild cognitive impairment could improve their memory through weight training and brisk walking.

The connections between physical and mental decline may not yet be completely understood, but it seems clear that chronic diseases play a major role in the process. While these are widespread, the encouraging news is that many, if not all, are preventable by healthier lifestyle choices.

Less salt in our food supply could save at least half a million Americans from dying prematurely over the next ten years, according to separate studies conducted at three universities, two American and one Canadian. If the average daily salt intake were to drop to 1,500 milligrams, as recommended by the Dietary Guidelines for Americans, the number of lives saved could more than double. All study results were published in the medical journal Hypertension, a publication of the American Heart Association (AHA).

Americans currently consume on average 3,600 milligrams of salt daily, mostly in form of sodium, widely used as an ingredient in processed foods. Sodium is considered a significant contributor to high blood pressure, which can lead to heart disease, heart attack and stroke, all leading causes of death in the U.S. today.

About a third of American adults, or 68 million, suffer from high blood pressure, a.k.a. hypertension, according to the Centers for Disease Control and Prevention (CDC). The condition was identified as a primary or contributing cause of nearly 350,000 deaths in the U.S. in 2008, the last time the CDC has updated its research on the subject.

Despite of these alarming statistics, there are currently no signs of improvement. Even better treatment has only shown mixed results. Less than half (46 percent) of high blood pressure patients have their condition under control, according to the CDC.

Because the salt content in processed food is already added before it reaches the consumer, there is little opportunity to make changes on an individual basis other than limiting one’s choices to fresh items like produce. This would also exclude many options in restaurants.

“Individuals can’t make this choice easily,” said Dr. Kirstin Bibbins-Domingo, professor of medicine and epidemiology at the University of California, San Francisco (UCSF), to ABC News. “So maybe we should find ways to work with the food industry,” she suggested.

The National Salt Reduction Initiative, a partnership started by the New York City Health Department that has expanded to nearly 100 city and state health organizations across the country, has been trying to get food manufacturers and restaurant operators to cut salt by 25 percent or more since 2008, the year of the organization’s inception. The current goal is to achieve a reduction of 20 percent by 2014.

Critics say that such measures are impractical and would make little difference. Public health advocates have been focusing on hypertension as if no other health threats existed, said Morton Satin, Vice President of science and research at the Salt Institute, a trade association for the salt industry, in response to the recent studies to ABC News. The association warns that low salt intake could produce its own set of health problems, especially for the elderly.

While most experts would agree that multiple factors can be responsible for the development of high blood pressure, including genetic predisposition, gender, age and other non-modifiable components, poor diet and lifestyle choices, which are modifiable and therefore preventable risk factors, usually play a much greater role. In a milestone conference on the connections between sodium intake and blood pressure, sponsored by the National Heart, Lung and Blood Institute (NHLBI), the participating scientists concluded that “an abundance of scientific evidence indicates that higher sodium consumption is associated with higher levels of blood pressure, [as demonstrated in] animal studies, observational epidemiologic studies, and clinical studies and trials.” They were also hopeful that more effective strategies could be developed to improve diet and lifestyles patterns that benefit the larger population.

Heart Health Month – An Important Reminder

February 8th, 2012 at 1:38 pm by timigustafson

February is “Heart Health Month.” Health advocacy groups and organizations like the American Heart Association (AHA), the National Heart Lung and Blood Institute (NHLBI) and the Centers for Disease Control and Prevention (CDC) want to remind us that heart disease is the most common cause of death in America and deserves more of our attention.

Sadly, heart disease has become nothing short of a national crisis in this country. “Heart disease takes the lives of far too many people in this country,” said Department of Health and Human Services (HHS) Secretary Kathleen Sebelius. “With more than two million heart attacks and strokes a year, and 800,000 deaths, just about all of us have been touched by someone who has had heart disease, a heart attack, or a stroke.”

Heart disease is also very expensive to treat. Cardiovascular disease and stroke hospitalizations have cost nearly $450 billion in health care expenses and lost productivity in 2010 alone.

“The sad truth is that these ailments are usually preventable, and in a perfect world I would be out of a job,” said Mehmet Oz, MD, a cardiothoracic surgeon and host of “The Dr. Oz Show.” “Unfortunately, I’m busier than ever,” he added.

Raising awareness is a crucial way to fight back against the spreading disease. In 2011, the HHS, in collaboration with the CDC and other government agencies as well as private organizations, has launched a program named “Million Hearts,” a nationwide initiative aimed at preventing one million heart attacks and strokes over the next five years. Among its many goals, the program wants to “empower Americans to make healthy choices,” such as avoiding tobacco use and reducing the amount of sodium and trans fat they eat, and to “improve care for people who need treatment” by encouraging them to take steps to better control their blood pressure, cholesterol levels and other major risk factors for cardiovascular disease and stroke.

“Million Hearts” is not the only awareness movement in the country. “Go Red for Women” is a nationwide program by AHA “to fight heart disease as the number one killer of women in America.” Observers can express their support by wearing red clothing or pins. “Choose to Move” is another AHA project dedicated to women’s heart health through physical exercise.

Sending the right messages is vitally important, especially for women, said Dr. Oz. “Many women and their health care providers believe that heart disease is less serious in women than in men. This is simply not true. Studies show that more women than men die within a year of having a first heart attack. Women are two to three times more likely than men to die following heart-bypass surgery, and more women than men die each year from congestive heart failure.

In fact, women may suffer from a completely different type of heart disease than men, according to Noel Bairey Merz, MD, director of the Women’s Heart Center at Cedars-Sinai Medical Center in Los Angeles, which is not yet fully understood and harder to detect, and therefore can often remain undiagnosed until it is too late.

The good news is that there are only a few causes of heart disease that are out of our control, such as genetic predisposition, family history and aging. The rest is a matter of choice. Even small lifestyle improvements can make a significant difference. Weight control, good nutrition, regular exercise and stress reduction are all part of that. Each one of these is fully achievable for everyone with enough commitment and willingness to make the necessary efforts. Raising awareness is a good start, but it doesn’t end there.

Even Slightly Elevated Blood Pressure Poses Health Risks

November 16th, 2011 at 10:39 am by timigustafson

If you think your blood pressure is normal, you may want to double-check with your doctor. According to new guidelines, blood pressure of 120/80 mmHg, which was until recently seen as within a healthy range, is now classified as elevated.

Scientists at the University of California, San Diego (UCSD) found that people under the age of 65 who were diagnosed with a condition called “prehypertension” had a 68 percent increased risk of suffering a stroke compared to those with normal readings.

Prehypertension is defined by the National Institutes of Health (NIH) as a systolic pressure (upper number) of 120 to 139 mmHg and a diastolic pressure (lower number) of 80 to 89. Higher readings than 140/90 are considered to be hypertension. Ideally, the normal range should be well below the prehypertension threshold.

When blood pressure rises, the heart has to work harder. If blood pressure remains chronically elevated, the risk of cardiovascular disease increases, which can eventually lead to heart attack, stroke or heart failure.

A primary risk factor is obesity. The greater the body mass, the more blood is needed to transport oxygen and nutrients. The higher volume of blood circulating through the blood vessels puts ever more force on the artery walls.

There are other causes as well. Atherosclerosis, the buildup of fatty deposits in the arteries, is quite common. Other contributing conditions are sleep apnea, kidney disease, thyroid disease and adrenal disease.

Poor diet- and lifestyle choices are most often (at least in part) responsible for high blood pressure to occur. But even some medications, including birth control pills, cold remedies, painkillers and other prescription drugs can play a role. So can recreational drugs like cocaine and amphetamines.

There is no cure for high blood pressure, only treatment through medication and lifestyle measures like diet and exercise.

Prehypertension should be seen as a warning sign, according to Dr. Bruce Ovbiagele, a professor at UCSD and lead author of the study that lead to the revised guidelines. “This doesn’t mean that people with prehypertension should start taking anti-hypertensive drugs. Instead, they should modify their lifestyle, maintain an ideal weight and lower their sodium intake.”

The worst you can do is to ignore the numbers, said Dr. Ovbiagele. “You shouldn’t be deceived because nothing seems to be going on.” Because there are no specific symptoms for prehypertension or hypertension, people tend to think they can live with the condition.

Nothing could be further from the truth. If you are overweight, even moderately, shed the extra pounds as soon as possible. Exercise regularly. Nothing is better for your blood pressure and your heart than a rigorous workout several times a week (consult with your doctor if you already have elevated blood pressure and don’t currently exercise). Eat plenty of fruits, vegetables, whole grains, fish and low-fat dairy products. Avoid foods that are high in sodium like processed and packaged food items. Eat foods that are low-fat, low-cholesterol and free of trans fats and other unhealthy ingredients. Cut back on meat, especially red meat. Drink alcohol in only moderation, preferably red wine. Last but not least, manage your stress and get enough sleep.

In Praise of the Mighty Blueberries

August 31st, 2011 at 1:19 pm by timigustafson

Blueberries have long been popular for their tangy flavor and multiple uses in desserts, yogurts, juices and baked goods. They also rank among the healthiest foods you can possibly eat. In fact, the list of possible health benefits from blueberries grows longer every year, as more medical studies uncover their incredible healing power.

Here is a short list of the more recent findings:

• Blueberries have been shown to shrink cancerous tumors and prevent the development and growth of cancer cells.

• Blueberries can slow down and even reverse age-related memory loss.

• Blueberries can help improve physical coordination and balance at an advanced age.

• Blueberries reduce cholesterol levels.

• Blueberries prevent urinary tract infections.

• Blueberries are low in calories and high in fiber, vitamin C and antioxidants, all of which makes them extremely nutritionally beneficial.

This seems a lot of punch to pack for such a plain little berry, but all these claims are backed up by growing evidence.

For example, a study conducted at Ohio State University in 2009 found that when lab rats with blood vessel tumors were fed blueberry extract, their cancer growth was halted and even reversed. The blueberry-fed rats lived on average twice as long as those that were given none. Blood vessel tumor is among the most common cancer types affecting young children and occurs in about three percent of all infants. Researchers hope that the use of blueberries may some day be part of the treatment of these usually inoperable tumors.

A separate study that was conducted in 2007 at Rutgers University in cooperation with the U.S. Department of Agriculture (USDA) found that a specific compound in blueberries, named pterostilbene, was able to inhibit the spread of cancer cells in the colon of lab rats. And in 2005, researchers at the University of Illinois reported that antioxidants in wild blueberries, called anthocyanins, could prevent certain cancers from forming and proliferating in the prostate and the liver. “Blueberries seem to have “cancer-fighting properties at all stages: Initiation, promotion and proliferation,” said Dr. Mary Ann Lila, the lead author of the study report. “Wild blueberry compounds offer a multi-pronged attack against cancer,” she added.

Blueberries have also been praised for their ability to reduce age-related deterioration of brain functions and memory. A research team from England concluded in 2008 that eating blueberries can actually reverse problems with memory and other cognitive functions. Almost ten years earlier, a USDA-sponsored study found that blueberries improved the physical coordination and balance in aging lab rats.

USDA researchers also reported findings of cholesterol-lowering properties in blueberries, based on animal studies they conducted in 2004. In fact, their experimentation showed that blueberries were more effective in lowering cholesterol levels than many widely prescribed cholesterol medications.

A 2004 study from Rutgers University confirmed that blueberries, like cranberries, can be helpful in preventing and healing urinary tract infections. A compound, called epicatechin, keeps infectious bacteria from attaching themselves to the bladder wall.

Besides these astounding health benefits, blueberries are also nutritional powerhouses. They are low in calories – one cup is 82 calories – high in fiber and loaded with vitamins, especially vitamin C. They rank among the top providers of antioxidants, which are essential to nutritional health. Antioxidants like anthocyanin, vitamin C, vitamin A, vitamin E and mineral selenium, and also copper (a highly effective anti-bacterial agent), zinc and iron (which raises hemoglobin and the concentration of oxygen in the blood), among other important micronutrients, boost the immune system and help to prevent infections.

In addition to its rich nutritional qualities, blueberries have the ability to neutralize so-called “free radicals,” which are unstable molecules that can cause many diseases and accelerate the aging process. This is mainly due to the concentrated presence of anthocyanin, the pigment that gives these berries their dark bluish color.

Some believers in the multiple powers of this “superfruit” think of blueberries also as an effective anti-depressant, although, to my knowledge, no conclusive research has yet been done in this regard. But it wouldn’t surprise me at all. I personally eat a bowl of blueberries every morning as part of my breakfast – and I haven’t had a bad day in a very long time. Maybe it’s the berries.
