Running Keeps You Younger

shutterstock_92618653As a once-regular runner, this headline was intriguing to come across: “Running really can keep you young, says CU-Boulder-Humboldt State study.”

The gist of the article is that seniors who run regularly also use energy more efficiently while walking, about the same as a typical 20-year-old.

But older people who walk for exercise rather than jog burn about the same energy walking as older, sedentary adults, and expend up to 22 percent more energy walking than the 20-something crowd. The study, led by Humboldt State Professor Justus Ortega, was published online Nov. 20 in the journal PLOS ONE.

“The bottom line is that running keeps you younger, at least in terms of energy efficiency,” said CU-Boulder Associate Professor Rodger Kram of the Department of Integrative Physiology, a co-author on the new study.

The study included 30 healthy volunteers with an average age of 69 who either regularly ran or walked for exercise. The volunteers all had been either walking or running at least three times a week for a minimum of 30 minutes per workout for at least six months.

Kram believes that mitochondria — small bodies found inside individual cells known as the cell “powerhouses” — are involved. Mitochondria generate chemical energy known as adenosine triphosphate (ATP) that powers our muscle fibers to help us move about, lift objects, and, in this case, run. People who work out regularly generally have more mitochondria in their cells, providing more energy to power larger muscles.

Guess I’ll have to get back into the habit.

The Grand Elm Playlot Project in Richmond

image-full;size$350,263.ImageHandlerI’ve never seen anything like it – a dangerous 1/2-acre park in one of the Bay Area’s most dangerous neighborhoods – the Iron Triangle in Richmond – turned into a thriving, beautiful oasis for the neighborhood’s children and families, who need the respite and the exercise. Here is a write up on it, below, with Toody Maher, the woman behind the transformation, described as well. It’s a truly uplifting project, and as Toody said, parks all over the country in distressed areas could do the same. (With the tenacity of someone like Toody…)

 

The Mighty Elm Playlot

Toody Maher knows the impact a local playground or park can have on residents’ health.

She can citestudies that show that children with a playground very near their home are much more likely to be a healthy weight, that kids are more active at a renovated playground, that more kids in low-income neighborhoods use a playground when there is adult supervision.

Everyday discrimination impacts mental health

Here are the questions nearly 5,000 African American and Caribbean adults were asked:

“How often do you receive poorer service than others at restaurants or stores?” (disrespectful discrimination);

“How often do people act as if they’re better than you are” (condescending discrimination;

“How often are you viewed as dishonest?” (character-based discrimination) and;

“How often are you threatened or harassed?” (hostile discrimination).

The vast majority (83%) said they’d experienced some type of discrimination in the past year. Half of respondents reported repeated discrimination of all types, and one in 7 reported frequent experiences of discrimination. The latter group had especially high rates of clinical depression and substance abuse.

The research, published in the August 2014 edition of Addictive Behaviors, also discussed life qualities that protect against the stressful. “Factors such as ethnic identity, spirituality and religiosity have been found to help protect against risk factors such as everyday discrimination,” said Trenette Clark, lead author of the study.

High obesity rates still burden blacks, Latinos

Obesity

The Robert Wood Johnson Foundation just released an excellent report on obesity rates in the United States. While adult obesity rates increased in six states, that’s a slower climb than in the past, when almost all states showed increases. And rates are leveling off for children, thankfully. Surprisingly, at least to me, California has the most very young obese children in the nation.

Yet there’s a continued burden of obesity among black and Latino populations, as the chart on the left shows. Keys reasons, as the report notes: “Disparate access to affordable healthy food and safe places to be physically active contribute to higher rates of obesity and related illnesses in Black communities in America.” It’s not safe to exercise in many communities, and one resident of a poor Oakland neighborhood said she was even afraid to walk to the corner store to get some produce and milk for dinner. So crime reduction plays a role in reducing these rates.

Ending absenteeism to change the future for struggling communities

In researching a book on distressed communities, nothing has become clearer than the role of education in lifting the health, and economic prospects, of a community. Yet as this article describes, poor kids face the greatest obstacles in succeeding in school. In one community I’m reporting in, a rural county in Northern California, 1 out of 6 students in the school district are chronically absent. There are many reasons, but among them are transportation challenges, lack of supervision and health issues.

How to Get Kids to Class

To Keep Poor Students in School, Provide Social Services

“According to the education researchers Robert Balfanz and Vaughan Byrnes at Johns Hopkins, children living in poverty are by far the most likely to be chronically absent from school (which is generally defined as missing at least 10 percent of class days each year)….”

Great summation of black/white health disparities

This write-up has a clear, narrative summary of what’s doing on with health disparities, especially among blacks. Excellent charts too.

From VOX:

WHITE PRIVILEGE IS THE BEST MEDICINE

With the eyes of the world on Ferguson, Missouri, our collective attention is focused on the different treatment of black and white people at the hands of America’s criminal justice system. The focus is well deserved. More than 50 years after the Civil Rights movement, it’s still true that half of the black men in the US wind up arrested at least once by the age of 23, and are ten times more likely to be murdered than white men.

But every single day, there are many more race-related deaths that result from a quieter but arguably even more violent act: systemic discrimination in the US health system.

lifeexp.0The truth is this: even today, in America, white privilege works better than most medicine when it comes to staying healthy….

Californians support soda warning label, new poll shows

-¥À³Both Republicans and Democrats robustly support labels warning that sodas and other sugar-sweetened beverages increases the risk of obesity, diabetes and tooth decay, according to a Field Poll released Thursday.

Two-thirds of Republicans and 80 percent of Democrats favored adding the labels to the sugary products, as did three-quarters of independent voters. The findings, which were commissioned by the California Endowment, a private health foundation, bolster prospects for new legislation introduced in California this month, which would require manufacturers of drinks with more than 75 calories of sugar per serving to add this warning:

“State of California Safety Warning: Drinking beverages with added sugar(s) contributes to obesity, diabetes and tooth decay.”

More than a third of U.S. adults and about one in six children between the ages of 2 and 19 are obese, according to the Centers for Disease Control and Prevention.

And regular soda consumers have sharply higher odds of becoming overweight: a 55 percent increase for children and 27 percent for adults. Research shows sugar-sweetened beverages are the largest source of extra “empty” calories in the American diet.

And teens are drinking even more of it. The UCLA Center for Health Policy Research reported recently that almost two-thirds of California teenagers in 2011-12 drank sugary drinks every day, up 8 percent from 2005-07.

The labeling legislation is the first in California to target sodas, and it’s a change in tactic after defeats in trying to get soda taxes passed.

Ballot proposals that would tax soda sales in El Monte in Los Angeles County and Richmond in Northern California failed, after campaigns marked by intense lobbying against them by the soda industry, which maintains that sugary beverages are unfairly implicated in the obesity crisis; lack of physical activity and poor food choices also play a role, the industry has asserted.

But the new Field Poll also shows support may be shifting in favor of a soda tax, as concerns mount about the social and health toll of excess weight. Two-thirds of those polled support a sugary beverage tax, although this time support did split by party lines, with only 47 percent of Republicans favoring a soda tax.

Feeling in control? It could add years to your life.

Margie Lachman, a professor of psychology at Brandeis University, led a recent study on one's sense of control and life expectancy.

Margie Lachman, a professor of psychology at Brandeis University, led a recent study on one’s sense of control and life expectancy.

I’ve long wondered if outlook could change one’s life expectancy odds, since part of what accounts for discrepancies in life spans relates to a sense of control. That’s why those higher on the social ladder live longer, even if those just below them on the rung have safe homes, good food, medical care, etc. More control means less stress, better health.

So a new study caught my eye. It reported that for a certain population (those with less than a college degree), a sense of control did indeed influence life spans.

“Health and longevity are not just due to health care access,” said Margie Lachman, a professor of psychology and director of the Lifespan Initiative on Healthy Aging at Brandeis University, who led the study. “Attitudes make a difference. How you construe your circumstances and challenges determine whether you take action or give up, or feel stressed or motivated.” Her comments appeared in a Health Day article, published by the National Institutes of Health.

Lachman and her colleagues looked at data from more than 6,100 U.S. residents who turned in health surveys from 1994 to 1996. They then looked at what happened to them by 2009, and found nearly 600 had died.

As other research has shown, the odds of dying was higher among those who had lower levels of education. But the researchers found that feeling a sense of control counteracted the increased risk.

The study, which was funded by the NIH, appeared online Feb. 3 in the journal Health Psychology.

So what accounts for the difference? “People with a high and low sense of control will see the same situation differently, perhaps as a challenge versus a threat,” Lachman said.

Shevaun Neupert, an associate professor of psychology at North Carolina State University, lauded the study for showing that being poor or uneducated doesn’t need to translate into feeling helpless.

“The idea that someone with low education can have high levels of perceived control and outlive their peers with the same education is a powerful finding,” she stated in the Health Day article.

Why Timeliness Confers Power

A community organizer leading a meeting.

A community organizer leading a meeting.

On Monday night I sat in on a community organizing action in Del Norte County in Northern California, as part of my reporting on a book project on community health. And organizing community members so they make their voices heard – effectively – is one sure way to improve a community’s well being, as collective voices have great power to bring about change.

One model for community organizing is called PICO (“People Improving Communities through Organizing”), and it’s active in Del Norte.

Without going into the details of how PICO works, I’ll share one rule it stresses that really struck me. The lead organizer explained to the assembled group why PICO-run organizing actions, which typically last an hour, ALWAYS start on time, and ALWAYS end on time. To set the scene of an action, in the audience are power brokers (i.e. elected officials, agency heads, executives, etc.) who are asked to publicly commit to supporting an action deemed critical by the organizers.

The mandate for on-time scheduling is rooted in respect, and the philosophy that “power respects power.”  When you start and end on time, you’re respecting other peoples’ time.

But there’s more to it than that, pointed out the leader of Monday’s action: Powerful people are often surprised when rabble-rousers (as they’re sometimes stereotyped) like community organizers are highly organized, and start precisely when promised – with all materials in order. And they’re just as impressed when an action ends when promised.

“Arriving prepared and on time shows you’re a team with power,” said Josh Norris, the lead organizer of a new organizing committee that’s formed in Klamath, Californa.

I’ve always viewed timeliness as a courtesy, but this adds a new dimension. It also confers power. That’s a new reason to follow that old rule of etiquette.

Deadly Discrimination

David Williams, a Harvard University professor with an expertise on the health effects of racism.

David Williams, a Harvard University professor with an expertise on the health effects of racism.

Beware of the small slights in life. Over a lifetime they add up to major loss of health, physical and mental, warns David R. Williams, a professor of public health, sociology and African and African-American studies at Harvard University.

For decades Williams has studied the connection between racism and diminished health. Recently his work percolated up in the news as he’s giving a few talks this week, at the invitation of Canadian health experts eager to close the gap between black and white populations there.

Worldwide, life expectancies are all strongly linked to socioeconomic status – job rank, income and education level. Minority populations typically end up on the lower end of the spectrum, and many nations are working to reduce those life span differences, which reach up to 20 years.

Between 1990 and 2008, the United States began making headway in its quest end the difference, with the most educated blacks gaining 6.7 years in life expectancy. But they still lag in lifespan behind their white counterparts, and Williams points to racism, or what he calls “microaggressions,” as the key hidden factor.

To quantify the effects of racism, Williams developed three statistical tools: The Major Experiences of Discrimination, Everyday Discrimination, and Heightened Vigilance scales.

Everyday discrimination, Williams found, extracts the greatest toll. Black Americans often report poor service in retail outlets or being followed as though they’ll shoplift, being passed over for important positions or promotions, and less attentive treatment from health care professionals, among countless slights. (The Tumblr site, http://microaggressions.tumblr.com, has numerous first-hand examples.)

Among the health ramifications: Greater risk of developing heart disease, depression, and premature delivery, as well as the buildup of abdominal fat, itself linked to diabetes, high blood pressure, and stroke.

Awareness starts the cure, Williams asserts. In a recent article in the (Halifax) Chronicle Herald, he advised pausing before subconsciously categorizing somebody based on the most common traits used to discriminate — race, gender and age. Instead, he suggested making a conscious effort to focus on the person as a unique individual.
