BPA linked to higher risk for obesity among young girls

A chemical commonly found in plastic food containers, water bottles and canned foods called bisphenol-A (BPA) has long been linked to serious health issues, including infertility and birth defects. Now, researchers say exposure to BPA may also be associated with a higher risk for obesity among puberty-age girls.

In a study published in the journal PLOS ONE, researchers measured the levels of BPA present in urine samples from 1,326 children between the ages of 9 and 12. Researchers discovered that girls who had higher levels of BPA in their urine had a greater risk for being overweight. The effect was not seen in the boys involved in the study.

Girls who had more than 2 micrograms per liter of BPA in their urine were twice as likely to be overweight, compared to girls with below normal levels of BPA in their urine. And girls that had more than 10 micrograms of BPA per liter in their urine had a ten times greater risk for obesity.

Dr. De-Kun Li, the study’s principal investigator and a reproductive and perinatal epidemiologist at the Kaiser Permanente Division of Research in Oakland, Calif., has been studying the effects of BPA for years.

“Animal (studies) started to show that BPA can impact metabolic processes, which often leads to obesity and diabetes,” Li told FoxNews.com. “So we decided to look at it (in humans).”

Li noted that though he expected to find a link between obesity and BPA levels, he didn’t expect it to be such a strong correlation.  

While the research does not necessarily prove BPA is the reason for the girls’ obesity, Li said that the effect is likely caused by the fact that BPA is an endocrine disrupter and acts similarly to the hormone estrogen, which impacts metabolic function.

Because of the damage that BPA incurs on the endocrine system, Li believes exposure to BPA is contributing to the global obesity epidemic.  

“Overeating a little won’t cause obesity, but (by) having this kind of endocrine damage without knowing it, and adding more food, the consequences are magnified,” Li said.

Though Li said there are currently no Food and Drug Administration (FDA) regulations forcing manufacturers to label how much BPA is used in packaging, he hopes this research will add to the body of evidence mounting against the chemical. He warns that people should try to avoid products containing BPA as much as possible.

“Buy BPA-free containers, particularly containers used for kids. Kids and fetuses are the most affected populations,” Li said. “Also try to reduce using plastics. It’s not feasible to use none, but reduce exposure to plastic containers…and reduce the use of canned foods.”

Li hopes to study the effects of BPA further, by testing its impact on unborn babies.

“I want to look when pregnant women, and their fetuses, are exposed to even small amounts of BPA, how it’s going to damage (them),” Li said. “When you damage the fetus, you damage the rest of their life.”

Baby boomers are killing themselves at an alarming rate, raising question: Why?

June 4, 2013

http://www.washingtonpost.com/local/baby-boomers-are-killing-themselves-at-an-alarming-rate-begging-question-why/2013/06/03/d98acc7a-c41f-11e2-8c3b-0b5e9247e8ca_story.html?tid=pm_local_pop

Last spring, Frank Turkaly tried to kill himself. A retiree in a Pittsburgh suburb living on disability checks, he was estranged from friends and family, mired in credit card debt and taking medication for depression, cholesterol, diabetes and high blood pressure.

It was not the life he had envisioned as a young man in the 1960s and ’70s, when “people were more in tune with each other, people were more prone to help each other,” said Turkaly, 63, who owned a camera shop and later worked at Sears. “There was not this big segregation between the poor and the rich. . . . I thought it was going to continue the same, I didn’t think it was going to change.”

Turkaly said he regrets his attempt to overdose on tranquilizers, which he attributes to social isolation. But in one grim respect he is far from alone: He is part of an alarming trend among baby boomers, whose suicide rates shot up precipitously between 1999 and 2010.

It has long held true that elderly people have higher suicide rates than the overall population. But numbers released in May by the Centers for Disease Control and Prevention show a dramatic spike in suicides among middle-aged people, with the highest increases among men in their 50s, whose rate went up by nearly 50 percent to 30 per 100,000; and women in their early 60s, whose rate rose by nearly 60 percent (though it is still relatively low compared with men, at 7 in 100,000). The highest rates were among white and Native American and Alaskan men. In recent years, deaths by suicide has surpassed deaths by motor vehicle crashes.

As youths, boomers had higher suicide rates than earlier generations; the confluence of that with the fact that they are now beginning to grow old, when the risk traditionally goes up, has experts worried. The findings suggest that more suicide research and prevention should “address the needs of middle-aged persons,” a CDC statement said.

There are no large-scale studies yet fleshing out the reasons behind the increase in boomer suicides. Part of it is likely tied to the recent economic downturn — financial recessions are in general associated with an uptick in suicides. But the trend started a decade before the 2008 recession, and psychologists and academics say it likely stems from a complex matrix of issues particular to a generation that vowed not to trust anyone older than 30 and who rocked out to lyrics such as, “I hope I die before I get old.”

“We’ve been a pretty youth-oriented generation,” said Bob Knight, professor of gerontology and psychology at the University of Southern California, who is also a baby boomer. “We haven’t idealized growing up and getting mature in the same way that other cohorts have.”

Even as they become grandparents and deal with normal signs of getting old, such as hearing and vision losses, many boomers are reluctant to accept the realities of aging, Knight said.To those growing up in the 1950s and ’60s, America seemed to promise a limitless array of possibilities. The Great Depression and World War II were over; medical innovations such as the polio vaccine and antibiotics appeared to wipe out disease and disability; the birth-control pill sparked a sexual revolution. The economy was thriving, and as they came of age, boomers embraced new ways of living — as civil rights activists, as hippies, as feminists, as war protesters.

“There was a sense of rebelliousness, of ‘I don’t want to live the way my parents did or their parents did,’ ” said Patrick Arbore, director and founder of the Center for Elderly Suicide Prevention at San Francisco’s Institute on Aging. “There was a lot of movement to different parts of the country. With that came a lot of freedom, but there also came a loss of connections. It was not uncommon to see people married three or four times.”

How did a generation that started out with so much going for it end up so despondent in midlife? It could be that those very advantages made it harder to cope with setbacks, said Barry Jacobs, director of behavioral sciences at the Crozer-Keystone Family Medicine Residency Program in Pennsylvania.

“There was an illusion of choice — where people thought they’d be able to re-create themselves again and again,” he said. “These people feel a greater sense of disappointment because their expectations of leading glorious lives didn’t come to fruition.”

Instead, compared with their parents’ generation, boomers have higher rates of obesity, prescription and illicit drug abuse, alcoholism, divorce, depression and mental disorders. As they age, many add to that list chronic illness, disabilities and the strains of caring for their parents and for adult children who still depend on them financially.

Perhaps a little more adversity in youth could have helped prepare them for the inevitable indignities of aging, Knight suggested, adding that “the earlier-born cohorts are sort of tougher in the face of stress.” Despite the hardships of life in the first half of the 20th century, he said, older generations didn’t have the same kind of concept of being stressed out.

Older generations also had clearer milestones for success. “They won the Great War, they saved the world,” said David Jobes, a professor of psychology at Catholic University and a clinician at the Washington Psychological Center in Friendship Heights.

Baby boomers, on the other hand, have struggled more with existential questions of purpose and meaning. Growing up in a post-Freudian society, they were raised with a new vocabulary of emotional awareness and an emphasis on self-actualization. But that did not necessarily translate into an increased ability to cope with difficult emotions — especially among men. Women tend to be better connected socially and share their feelings more freely — protective factors when looking at their risk for suicide. And African Americans and Hispanics tend to have lower rates of suicide than whites, possibly because of stronger community connections, or because of different expectations.

Combine high expectations with a faltering economy, and the risk goes up.

“We know that what men want to do is work — that’s a very strong ethic for them,” Arbore said. “When their jobs are being threatened, they see themselves as still needing to be in that role; they feel ashamed when they’re not able to find another job, or when their home is being foreclosed on. . . . The idea that so many of us in this country have been brought up with — that you work hard, you get your house, you get your American dream, everything is rosy — it hasn’t worked out. A lot of these boomers aren’t going to earn as much money as their parents did. They aren’t going to be as secure as their parents were. And that’s quite troubling for the boomers.”

Mike Murray of Rising Sun, Md., struggled with major depression for most of his adult years, even as he married, raised two children and owned a successful quarry maintenance and grass-mowing business.

His wife, Becky Murray, who ran the business with him, describes him as a perfectionist. “He always did well in school, he was a straight-A student; anything he did, he did well,” she said.

But in 2004 a back injury forced him to go on disability — and on powerful pain medications. In 2010 he made two attempts to overdose, and in early 2011, two days after his 49th birthday, he killed himself with a shotgun.

“He was handsome, he was smart, people loved him,” Murray said, but added that he felt increasingly depressed. “The pain medication changes the chemicals in your brain, so he felt like there was less of him,” she said. “He probably felt, here I am, this smart, capable person, but I can’t conquer this thing in my mind.”

And while he was grateful for his disability checks, she said, “It was very hard for him to accept this and to not contribute to his family.”

Nor are women immune. When Liz Strand’s 53-year-old friend killed herself two years ago in California, her house was underwater and needed repairs, she had a painful ankle that was exacerbated by being overweight, and although she had tried to find a partner, she was unmarried, like one-third of baby boomers.

“When everything started exploding on her it was too much for her,” Strand said, adding that as a boomer she herself recalls the shock of realizing that the good times were not eternal. “I just thought everything was going to continue to improve. I remember hearing at one point in a college class that, ‘No, it’s a pendulum.’ It was a real wake-up call.”

Believers from an early age in the power of medicine, boomers are more likely than their elders to turn to drugs, alcohol or even plastic surgery to mask their problems. “Boomers do not want to suffer,” Arbore said.

Exacerbating boomers’ anxiety is a sense that the world is more treacherous than when they were young, he said. Then, the communist threat and the atom bomb loomed large, but they were distant and abstract; attacks like the ones on the World Trade Center and the Boston Marathon have changed this paradigm.

“These events used to happen 6,000 miles away; now they happen here,” Arbore said.

It doesn’t help to live in a society that continues to worship the young. “We don’t venerate our elders as some cultures do,” Jobes said.

It is unclear whether younger generations will follow or buck the boomer trend as they age, or if boomers will continue to kill themselves at such high rates as they move into retirement.

“There are people who believe that this won’t hold true, that the baby boomers as they grow older will have some kind of protective effect,” said Yeates Conwell, professor of psychiatry at the University of Rochester School of Medicine. “They have strength in numbers, they have quite a lot of political clout and by and large the financial resources of the baby boomers are quite high.”

For Turkaly, the Pittsburgh man, it helps to know that statistics show he is not the only guy his age having a hard time.

“I guess it makes me feel better, ’cause I’m not quite as alone as I think I am,” he said. “It’s not just me; it’s just the way things happened.”

Rise in obesity poses ‘dementia time bomb’

May 12, 2013

http://www.bbc.co.uk/news/health-22479049

Ever-growing waistlines could result in a big increase in the number of people who develop dementia in the future, researchers have warned.

Previous studies have shown that being overweight in middle age increases the odds of developing the mental disorder.

Data presented at the European Congress on Obesity suggests stemming the rise in obesity will cut dementia.

The Alzheimer’s Society charity said regular exercise and a healthy weight were important for reducing risk.

Piling on too many pounds is known to be bad for the body, but there is growing evidence that it is also bad for the mind.

£940m saving predicted

Nobody knows exactly what causes dementias such as Alzheimer’s disease, but body weight appears to be a risk factor.

One study of 8,500 Swedish twins showed that those with a body mass index (BMI) greater than 30, who are classified as obese, were almost four times as likely to develop dementia as those with a normal BMI.

“Obesity is a major concern that’s going to have a major economic impact on the country”Tim Marsh UK Health Forum

Even those who were clinically overweight, a BMI between 25 and 30, were 71% more likely to develop dementia.

In England 24% of men and 26% of women are obese.

Researchers from the UK Health Forum used computer models to compare what would happen if obesity rates stayed the same or increased to 46% of men and 31% of women by 2050, which has been predicted by some groups.

They said rates of dementia would go from 4,894 cases in every 100,000 people over 65 to 6,662 cases in every 100,000 people over 65.

Keeping obesity levels constant would save around £940m in dementia care, the study predicted.

‘Immediate impact’

Tim Marsh of UK Health Forum said: “We’ve known for a long time about the risks to cardiovascular disease, stroke, cancer, type 2 diabetes, so this is a new concern.

“Obesity is a major concern that’s going to have a major economic impact on the country and this further compounds that.

“The trouble is there’s a 25-year lag in this. Obesity started increasing in the 80s.”

Jessica Smith, a research officer at Alzheimer’s Society, said: “It’s easy to see the immediate impact of piling on the pounds, but we can’t afford to ignore the long-term effects.

“Evidence shows that obesity increases the risk of developing dementia. This study highlights the impact obesity will have on the numbers of people with the condition in the future.

She added that “maintaining a healthy weight and exercising regularly – especially in midlife – are hugely important in reducing your risk”.
