Report: One in Four Americans over 50 is Inactive

Researchers from the Centers for Disease Control and Prevention (CDC) released new data on the prevalence of physical inactivity among adults age 50 years and older. Inactivity is 63745_151_previewdefined as no activity beyond what one has to do just to get through the day (activities of daily living). When asked “During the past month, other than your regular job, did you participate in any physical activities or exercises such as running, calisthenics, golf, gardening, or walking for exercise?”, 27.5% of the adults surveyed responded ‘no’ – indicating that more than one in four adults 50 and over are inactive.

The prevalence of inactivity varied by region. It was highest in the South (30.1%), followed by the Midwest (28.4%), Northeast (26.6%), and West (23.1%).  The survey also found that inactivity was significantly higher for women, Hispanics and non-Hispanic blacks, and adults with one or more chronic diseases. Inactivity for cancer survivors was reported at just 31.6%.

We asked Colleen Doyle, MS, RD, managing director of nutrition and physical activity at the American Cancer Society for her take on the new data.

“This report is a wake-up call and quite literally a ‘call to action.’ Being physically active reduces the risk of premature death and can help reduce the risk of many chronic diseases, including cancer. Physical activity also helps support improvements in quality of life and healthy aging. While we’ve known that the level of physical inactivity among adults is far too high, this report underscores the fact that inactivity is highest among those who could benefit the most from it.

“Adults with at least one chronic condition were more likely to be sedentary than those without a chronic condition. In the case of cancer, more than 31% of cancer survivors reported getting no physical activity outside of daily life. Studies have shown that exercise can improve cancer survivors’ physical functioning, fatigue, anxiety, depression, self-esteem, and happiness. In addition, studies among survivors of certain cancer types have shown that physically active survivors have a lower risk of recurrence and improved survival compared with those who are inactive.

“For those who do not have a history of cancer, the evidence is clear that being active and reducing sedentary behavior can help reduce the risk of a variety of types of cancer.

The American Cancer Society recommends that everyone, including cancer survivors, strive to be active at for least 150 minutes per week and to avoid inactivity. To encourage and support all individuals in increasing their physical activity level is critically important to our mission to reduce cancer incidence and mortality, as well as to improve the quality of life of cancer survivors.

“It’s important to consider why many Americans are not meeting physical activity guidelines. And there are likely multiple reasons. What is evident, though, is that in many communities, living a physically active lifestyle can be a challenge. The ways in which communities are designed and built can present challenges. When everyday destinations are far from home, walking, bicycling or other forms of active transportation may not be an available or convenient option. Safety concerns, such as lack of access to sidewalks, bike lanes, and traffic control measures, can also be barriers to being active. Lack of access to parks, public pools and green space, which tends to be higher in poor and under-served communities, also contributes to lower rates of physical activity.

“There is much being done but much more that needs to be done to reduce physical inactivity and help people of all ages and health conditions live more physically active lives. All sectors can work together to:

  • Support safe, efficient, and pedestrian-friendly public transit systems and transit-oriented development, and to create and improve walking trails and parks.
  • Open and promote places in communities for individuals to be active such as schools, parks, and malls.
  • Provide evidence-based community programs that help adults, including those with chronic conditions like cancer, start and continue to be active.
  • Work with health professionals to link their patients to community programs and resources for physical activity.

“And as individuals, there is much we can do, too. Commit to be more active yourself, on a daily basis. Encourage and support your family members, friends and co-workers to do the same. Speak up; participate in local planning efforts that support safe and convenient places to be active. Working collectively, we can help create healthier environments to support all of us in living a more physically active life.”

The Numbers behind the ProtecT Trial

This week’s release of the first study comparing outcomes between surgery, radiation, and active surveillance got a lot of buzz. But even then, some pretty important details did not get as much coverage as they probably could, and maybe even should have.

Here’s a quick look at the numbers behind two major statistics you may have heard in the coverage of this important study.

1: Men assigned to active surveillance had twice the risk of cancer progression and spread compared to men who got immediate treatment.

This is why it’s important to know the difference between relative risk and absolute risk. Relative risk is in relation to some other thing (e.g.: “twice as likely”). Absolute risk is what the chances actually are (e.g.: 1 in 6).

progressionSo “twice the risk” tells us something important, but not everything important. Absolute risk tells a more complete story.

Among those men who got immediate treatment, three out of 100 saw their cancers progress in ten years.

Among men under active surveillance, the rate was six out of 100.

So immediate treatment (surgery or radiation) did indeed result in half the risk. But the increase in “absolute risk” was 3%, which helps put “twice the risk” into perspective. Also, it’s a reminder that current treatment is not foolproof, and that some cancers progress despite our best efforts.  

2: More than half of men undergoing active surveillance ended up receiving treatment anyway.

Based on this stat, it would be easy to say all of the men diagnosed with early-stage prostate cancer using PSA might as well have gotten treatment. But take a closer look at the numbers.

As it turns out, protectabout third of the men assigned to active surveillance decided with their doctors to undergo treatment anyway. And understandably. Imagine the anxiety of knowing there’s a cancer inside you, for years. 

Meanwhile, 20% of the men doing active surveillance saw their cancer progress enough to warrant more radical treatment. And just as important: 44% of men made it through the ten years with no progression.

No one’s saying these details change the outcome or conclusion of the study. Seemingly everyone agrees, as my  favorite chief medical officer said yesterday, that the study “will help inform [the] discussion for men making what is a highly personal, and often difficult choice.” Let’s be sure, then, that men hear the numbers behind the stats.

New study compares surgery, radiation, and active surveillance in prostate cancer

36718_66_previewA long-awaited study from researchers in the United Kingdom compares three major approaches: surgery (radical prostatectomy), radiation, and active surveillance (also known as ‘watchful waiting’) for men with localized prostate cancer diagnosed with prostate specific antigen (PSA) blood test, and has some eye-opening results.

The report, appearing in the New England Journal of Medicine, finds that after ten years, men undergoing either of the three approaches had similar, low rates of death from prostate cancer. Surgery and radiotherapy reduce the risk of cancer progression over time compared with active monitoring, but cause more side-effects. We asked Otis W. Brawley, M.D., chief medical officer, for his response to the study.

“This study tells us that prostate cancer detected by PSA grows very slowly. Only about 1 in 100 men diagnosed with prostate cancer using PSA died of prostate cancer over ten years, a mortality rate that was lower than what the authors expected to see.

Otis W. Brawley, MD, Chief Medical Officer, American Cancer Society

“The men in the study had the same mortality rate regardless of the treatment they received, even when that treatment was no treatment. This study has just ten years of data, and it may take 20 or 25 years to see survival improvements from treatment, so we cannot say yet with certainty whether and how much of an advantage treatment has over no treatment. We can only say that at ten years, there is no difference.

“Men who received treatment did have half the risk of cancer spread, known as metastatic disease, of men who were monitored carefully (~2.5%-3% of men receiving surgery or radiation versus 6% of men in active surveillance). But a significant proportion of the men whose cancer had spread had no symptoms.

“On the other hand, the men receiving treatment were more likely to have side effects, some of them serious, over the ten years; things like bowel, bladder, and sexual dysfunction. Men who were monitored carefully without treatment, of course, avoided those side effects. And if they showed signs of their cancer spreading, those men could and did get treated.

“We may eventually find out that treatment using radiation and surgery will reduce the risk of death from prostate cancer decades later. We will also need to carefully measure if it reduces death from other causes, as well, to get a full picture of the risks and benefits of treatment.

“This paper shows clearly that treatment, whether with radiation or surgery, can reduce the chances of metastatic cancer. But it also shows that observation, or active surveillance, is a reasonable option for men diagnosed with localized prostate cancer through PSA screening and especially for men diagnosed with low or moderate grade localized disease.

“As the authors point out, active surveillance and/or delayed treatment avoids the side effects from treatment in those who do not need treatment, but there is an increased risk of cancer progression and spread, and some symptoms may increase gradually over time.

“The American Cancer Society recommends men be informed of the potential risks and potential benefits of prostate cancer screening and treatment before making a decision about whether to be screened. This study will help inform that discussion for men making what is a highly personal, and often difficult choice.”

Cancer vs. Heart Disease: What’s Behind the Numbers

A new report from the Center for Disease Control and Prevention’s (CDC) National Center for Health Statistics says cancer has replaced heart disease as the leading cause of death in 22 states as well as in non-Hispanic Asian/Pacific Islander and Hispanic populations.

For those who review these numbers regularly, it wasn’t really new information. Just a few months ago, the American Cancer Society’s annual Cancer Statistics report found death rates from cancer had surpassed those from heart disease in 21 states. The new report, which used newer data, added one more state to the list. Our specialty Statistics reports have also noted that cancer is the leading cause of death in Hispanics and in Asian American/Pacific Islanders (AAPI).db254_fig1

The story behind these numbers is interesting, and important. To begin with, it would be easy to look at the report’s chart on deaths from cancer and heart disease and conclude cancer deaths are climbing at a rapid pace. In fact, cancer death rates continue to drop at about 1% to 2% per year. The number of deaths is increasing, but that’s only because we have a growing, aging population.

As for the closing gap between cancer and heart disease: while cancer death rates have been dropping since 1990, rates of heart disease deaths were dropping even faster and for a longer time: by more than 2% a year, and at times as fast as 4%, from at least 1969 to 2010.

The American Cancer Society was among those who had estimated that cancer would overtake heart disease as the leading cause of death overall in the United States during the current decade. But, as so frequently happens, reality stepped in: the death rate from heart disease has begun to flatten, possibly due to rising rates of obesity, or perhaps because we are reaching a limit on our ability prevent deaths from heart disease. Meanwhile cancer death rates continue their steady descent. That change in heart disease deaths slowed the closing gap.

db254_fig2Another interesting aspect of this: those states where cancer has overtaken heart disease are actually doing better overall, with generally lower death rates for both heart disease and cancer. It’s because heart disease deaths are so low in those states that cancer is the top cause of death.

Finally, there’s the age factor. We frequently say cancer is a disease of aging. That goes double for heart disease. Cancer is also the leading cause of death in the U.S. in people ages 40-79 years because heart disease tends to occur at even older ages than cancer. In fact, the reason cancer is the leading cause of death in Hispanics and Asian/Pacific Islander populations is because these are younger populations, not because they have more cancer. Indeed, heart disease is the leading cause of death in these populations in the older age groups (80+).

9/11 and Cancer: Behind the Headlines

As we seem to learn every month or so, reporting on statistics is tricky business (When Skyrocketing Isn’t July 19, 2016). The latest example concerns WTChealth risks associated with exposure to the terror attack on the World Trade Center (WTC) on 9/11.

The headlines could easily be interpreted as saying that the cancer risk among people exposed to the WTC disaster has tripled in the past few years, or even that those exposed to the disaster have three times the risk of developing cancer.

It doesn’t say either of those. What is does say is important, and could be easily lost in the coverage.

Cancer was first designated as a WTC-related condition in October of 2012. Coverage of cancer by the WTC health program is based on the presence of probable and known carcinogens in the dust and fumes resulting from the building collapse.

The new reported number (5,441) represents the number of cancers certified for coverage (the number may reflect more than one cancer in a given individual).

The fact is, we really don’t know what number of cancers would be expected in WTC-exposed populations. So far, epidemiological studies of populations who had WTC-exposure generally find modest increases in overall cancer risk, on the order 10 to 30 percent higher than average.

It is important to recognize that it often takes 20 or more years after an exposure for cancers to occur. Only then will we know the real risk. Until then, health officials continue to monitor those exposed to potential carcinogens to identify potential emerging cancer risks.

If you want to learn more about this issue, the American Cancer Society’s Elizabeth M. Ward, PhD, senior vice president of intramural research, recently hosted a roundtable discussion on “Cancer and the World Trade Center Health Program.” Dr. Ward  serves as chair of the World Trade Center Health Program (WTCHP) Scientific and Technical Advisory Committee (STAC).

Olympic Rings… All of Them Red

One of the interesting developments at the Summer Olympics has been the sudden appearance of red circles on athletes’ skin. It turns out Michael Phelps and others are displaying signs of “cupping,” one of the more unusual ‘health’ practices around.

 

 

This has led to questions about the technique’s use not only to treat the pain of athletics, but other conditions, including cancer. We asked Ted Gansler, MBA, MD, MPH, strategic director of pathology research, what’s known about the treatment.

“According to a recent review , ‘Cupping therapy may have benefit in treating pain-related conditions, acne and facial paralysis, however, confirmed conclusions could not be drawn due to the low quality of the original studies.’ 

“In other words, these studies were conducted in ways that do not provide convincing evidence of benefit. Because of the nature of this treatment, a substantial placebo effect is possible. It is also likely that consensus is biased because studies reporting some benefit are more likely to be published than those that did not. Furthermore, there is no scientific rationale for expecting any health benefit from cupping.

“There is absolutely no credible evidence that cupping can cure cancer or shrink tumors. However, serious side effects from cupping are unlikely. The most likely harm for people with cancer is that they might choose cupping instead of science-based treatments that are proven to help them live longer and relieve symptoms.

“For people with cancer who want to try non-mainstream, complementary methods in addition to conventional treatment for relief of pain, there are several (massage therapy, music therapy, acupuncture, and exercise) that have more promising evidence, according to the Society of Integrative Oncology.”

A Healthy Journey Begins with 10,000 Steps

bracelet-1502602_1920The rise and increasing use of pedometers, Fitbits, and other devices to measure activity has brought renewed attention to “10,000 steps,” an idea to help promote physical activity in the United States. And it has some asking: is 10,000 steps enough?

We asked Kristen Sullivan MPH, MS, director of nutrition and physical activity, what she thinks of the “10,000 steps” initiative.

“The push to get Americans to take 10,000 steps per day is very positive, and could help people increase physical activity, a key part of their health. Tracking steps is a simple intervention and can be a motivating factor to get people to increase their activity.

“It’s important to note that people should be aiming to *add* intentional physical activity, above and beyond their typical daily activity, to reach the 10,000 step goal. Many people get 4000-6000 steps just from the activities of daily living. One mile takes about 2000 steps, so adding 4000 steps would be adding about two miles; about equal to 30 minutes of moderate activity. So setting a goal of reaching 10,000 steps is a good way to add activity beyond the typical activity of daily life.

“The American Cancer Society recommends that adults get at least 150 minutes of moderate activity (like brisk walking) or 75 minutes of vigorous activity (like jogging), or a combination of these, each week. That works out to about 30 minutes of moderate activity, 5 times per week. As long as reaching the 10,000 step goal includes at least 30 minutes of moderate activity, it’s a good way to improve health.

eggs-1467286_1920“For people who are trying to lose weight, it’s important to remember that changes in diet, in addition to physical activity, are critical to weight loss. Without dietary changes, one could easily be taking 10,000 steps a day and not lose weight, and might even gain weight. As many diet and exercise experts say” you can’t outrun your fork!”
