Japan's central bank pledges new stimulus to combat deflation









WASHINGTON — In unveiling a new stimulus plan, Japan's central bank for the first time set an ambitious inflation target aimed at breaking the nation out of its long deflationary trap and economic stagnation.


But many analysts and investors were disappointed with Tuesday's action.


They said the moves by the Bank of Japan, in response to relentless nagging by Japan's new prime minister to be more aggressive, fell far short of what was needed to put the world's third-largest economy on a path of sustained growth — offering little hope that Japan would provide a boost to the fragile global economy any time soon.





Japan's economy shrank in the third quarter amid weakening exports and consumer spending, and economists said it was likely to report a contraction for the fourth quarter, technically putting it in recession.


Deflation has long been a big part of Japan's economic woes. The trend of falling prices undermines growth by sapping consumers' spending and business profits, hurting jobs, wages and investment.


The country has been in a mild deflation in the last year. To combat that, the Bank of Japan adopted a 2% inflation target — double its previously stated goal of 1% and in line with other central banks in advanced economies, including the Federal Reserve in the U.S.


And much like the Fed, Japan's central bank pledged to pump more money into the financial system by buying government bonds indefinitely every month in a bid to meet its target.


Although the Fed's focus has been on bringing down America's stubbornly high unemployment rate, Japan's central bank is aiming to spur more consumer spending, in part by trying to create expectations that prices will rise, a strategy that not everyone agrees will work.


Japan's new prime minister, Shinzo Abe, praised the central bank's action, calling it "bold" and "epoch-making." The Bank of Japan's statement was issued jointly with Abe's government, which for its part pledged "all possible decisive policy actions" to grow the economy.


But the announcement was met with widespread skepticism from financial markets and experts. For one thing, the central bank's stepped-up buying of government bonds would amount to about 13 trillion yen a month, or about $147 billion, not nearly as much as analysts were expecting.


Furthermore, the Bank of Japan said it would not begin such purchases until early 2014, a delay that puzzled experts.


Takeo Hoshi, a finance professor at Stanford University, said it wasn't clear exactly why the central bank was delaying the expanded stimulus until next year. But he noted that the Bank of Japan is concerned about providing artificial support to unhealthy businesses and fostering undisciplined fiscal spending by buying government bonds and keeping interest rates low.


Hoshi said his bigger concern with Tuesday's joint statement was the lack of concrete steps that Abe's government said it would take to address long-running needs in the Japanese economy, such as deregulation and policies to strengthen competitiveness.


"The fundamental problem is that Japan's potential growth rate has declined over the last 20 years, and Japan hasn't done enough structural reforms to change that," said Hoshi, who directs the Japanese program at Stanford's Asia-Pacific Research Center.


The new 2% inflation-targeting strategy by itself won't drive more consumer spending, said Japanese economics expert Richard Katz, because "people keep expecting inflation and it never happens."


"When they expect more inflation, it actually causes them to spend less because prices go up, but people don't think wages will go up," said Katz, chief editor of the Oriental Economist Report, a monthly newsletter that specializes in Japan and U.S.-Japan relations.


The answer to Japan's economic problems, Katz said, was to provide stronger monetary stimulus and more efficient fiscal spending, along with a series of structural reforms that would enable Japan to become more productive in the face of a shrinking workforce and a population that is aging and saving less.


The Bank of Japan's action also drew criticism from Jens Weidmann, president of Germany's Bundesbank. He warned of government infringement in central bank authority and a resulting "politicized exchange rate" that could lead to currency wars as countries look to bolster economic growth through exports.


Japan, for decades an export powerhouse with perennial surpluses, has been running a trade deficit for the last two years. As prime minister, Abe has sought to devalue Japanese currency to help the country's export industries. The central bank's pledge to buy more bonds could help put further downward pressure on the yen.


Still, experts don't think that the yen will fall much further. Even if it dropped 10%, they said, it would probably have only a minor effect on the overall economy.


"I don't think trade surpluses will come back for Japan," Stanford's Hoshi said. "They need to come up with a new growth model."

In Obama's inaugural speech, a sweeping liberal vision









WASHINGTON — Allowing that "our journey is not complete," President Obama offered a robust liberal vision of America in his second inaugural address, embracing gay rights, action on climate change and a substantial role for government even as he acknowledged the challenges of a bitterly divided nation.


An ocean of American flags waved under overcast skies and hundreds of thousands of faces tilted up just before noon Monday as Obama stood on the Capitol's West Front and repeated the oath of office in America's 57th presidential inauguration.


Chants of "O-ba-ma" rose, echoing from a packed National Mall. The atmosphere was festive, but the fevered excitement that welcomed America's first African American president four years ago had been toned down. Still, though the crowd appeared smaller, it may rank as one of the largest for an inaugural celebration.





In an 18-minute speech, Obama paid tribute to the vast cultural, demographic and political changes that twice helped sweep him into office.


He also highlighted themes of national unity, borrowing language that even the most ardent tea party follower would endorse — praising "the patriots of 1776," describing freedom as "a gift from God," endorsing healthy skepticism of "central authority," and describing as "fiction" the notion that government can solve all ills.


But Obama made clear he views government as essential to fix the nation's problems and to guarantee the security of its citizens, reaffirming Democratic ideology stretching from the days of Franklin D. Roosevelt's New Deal.


"Medicare and Medicaid and Social Security, these things do not sap our initiative," he said. "They do not make us a nation of takers. They free us to take the risks that make this country great."


The remarks were an allusion to one of the fiercest arguments of the presidential campaign — when Republican nominee Mitt Romney described 47% of Americans, Obama supporters, as overly reliant on government — as well as to attacks on entitlement programs during recent budget battles in Congress.


Obama became the first president to use an inaugural address to call for an end to discrimination against gays and lesbians, equating it with landmark movements for women's suffrage and African American civil rights.


"Our journey is not complete until our gay brothers and sisters are treated like anyone else under the law," Obama said as the crowd applauded.


Obama, who long said he was evolving on same-sex marriage, waited until his reelection campaign was in full swing last year before he announced his support.


Speaking on Martin Luther King Jr. Day, a federal holiday, Obama alluded to the slain civil rights leader after putting his hand on two Bibles — one owned by King, and the other used at the 1861 inauguration of Abraham Lincoln.


Obama first took the oath of office from Chief Justice John G. Roberts Jr. at the White House on Sunday, when his term officially began. On Monday, Roberts administered the oath again, and the two men spoke slowly and carefully — unlike four years ago, when they mangled the text and had to arrange a private do-over at the White House.


Former Presidents Bill Clinton and Jimmy Carter, both Democrats, and their spouses were among the dignitaries who bundled up in heavy coats on a wintry gray morning to witness the public oath. The other living former presidents, Republicans George H.W. Bush, who was recently released from two months in the hospital, and his son, George W. Bush, were absent. Both issued warm statements of congratulations to the Obamas.


In his address, Obama offered an ideological primer on Democrats' beliefs, rather than specifics of the fights likely to dominate the upcoming session of Congress.


He cited Newtown, referring to the horrific elementary school shooting in Connecticut last month, but did not explicitly mention gun violence or firearms control.


He declared that the nation could not succeed "when a shrinking few do very well and a growing many barely make it," the kind of language that sparked Republican complaints during the presidential race that he was engaging in class warfare. But he did not say how he would rectify the disparity.


And while he emphasized the need to rise above "party or faction," he aimed a series of barely concealed zingers at his opponents, including those who deny climate change. He said failure to respond to that threat "would betray our children and future generations," but offered no clues of what he might do.


"We cannot mistake absolutism for principle," he said in another pointed passage, "or treat name-calling as reasoned debate."


Some Republicans said they searched in vain for olive branches. Sen. John McCain (R-Ariz.), who lost to Obama in 2008, said the president did not reach out to "those on the other side of the aisle in a plea to work together."

Beyonce, Hudson do star turns at inauguration


WASHINGTON (AP) — Beyonce drew a loud cheer at the inauguration Monday even before her impressive rendition of the national anthem. But in the role she played four years ago singing for the president and first lady at the inaugural ball was her "Dreamgirls" co-star Jennifer Hudson.


If President Barack Obama's first inaugural theme seemed to be summed up by Beyonce's "At Last," this time it was Hudson's version of Al Green's "Let's Stay Together."


Hudson was among the entertainment at Monday night's inaugural balls, joined by Stevie Wonder and Alicia Keys, who modified her hit "Girl on Fire" to sing "He's the president and he's on fire ... Obama's on fire. Obama's on fire."


The crowd at the official Inaugural Ball joined in with the Grammy-nominated fun. anthem "We Are Young."


And Wonder got small knots of dancers going with crowd-pleasers such as "Signed, Sealed, Delivered I'm Yours."


Earlier in the day, the applause for Beyonce started when she took her place with Jay-Z at the Capitol to watch President Barack Obama take the oath for his second term in office. The two stopped to chat with the Rev. Al Sharpton.


James Taylor kicked off the musical performances, strumming his guitar and singing "America the Beautiful." Kelly Clarkson followed with a different arrangement of "My Country 'Tis of Thee." Then Beyonce was introduced and the crowd again roared its approval.


Beyonce had a definite fan in Supreme Court Justice Clarence Thomas, who applauded eagerly after she finished singing the national anthem. She offered R&B-esque vocal riffs as she sang on and the crowd seemed to love it, cheering loudly as she finished. Clarkson, too, hit high notes.


Beyonce may have been the star musical attraction, but she had plenty of company from Hollywood at the Capitol on Monday. Katy Perry and John Mayer sat side-by-side, with Perry in an orange-striped coat and wide hat, and Mayer in dark sunglasses. Singer-songwriter Ke$ha was there, too.


People flocked to the colorful pop star, snapping photos. And Perry did the same, taking shots of "Girls" actress and daughter of news anchor Brian Williams, Allison Williams.


Actress Eva Longoria was seated on the platform outside the Capitol after making an appearance at a Kennedy Center performance Sunday night. Perry sang at the children's concert the night before.


Former Boston Celtics great Bill Russell was in the crowd, too, along with actor Marlon Wayans.

The Week: A Roundup of This Week’s Science News





“Science,” a colleague once said at a meeting, “is a mighty enterprise, which is really rather quite topical.” He was so right: as we continue to enhance our coverage of the scientific world, we always aim to keep the latest news front and center.




His observation seemed like a nice way to introduce this column, which will highlight the week’s developments in health and science news and glance at what’s ahead. This past week, for instance, the mighty enterprise of science addressed itself to such newsy topics as the flu (there’s still time to get vaccinated!), and mental illness and gun control.


In addition to the big-headline stories that invite wisdom from scientists, each week there is a drumbeat of purely scientific and medical news that emerges from academic journals, fieldwork and elsewhere. These developments, from the quirky to the abstruse, often make their way into the daily news cycle, depending on the strength of the research behind them. (Well, that’s how we judge them, anyway.)


Many discoveries are hard to unravel. “In a way, science is antithetical to everything that has to do with a newspaper,” the same colleague observed. “You couldn’t imagine anything less consumer-friendly.”


Let’s aim to fix that. Below, a selection of the week’s stories.


DEVELOPMENTS


Health


Strange, but Effective


People with a bacterial infection called Clostridium difficile — which kills 14,000 Americans a year — have a startling cure: a transplant of someone else’s feces into their digestive system, which introduces good bacteria that the gut needs to fight off the bad. For some people, antibiotics don’t fix this problem, but an infusion of diluted stool from a healthy person seems to do the trick.


Genetics


Dig We Must



Hillery Metz and Hopi Hoekstra/Harvard University



Evolutionary biologists at Harvard took a tiny species of deer mice, known for building elaborate burrows with long tunnels, and bred it with another species of deer mice, which builds short-tunneled burrows. Comparing the DNA of the original mice with their offspring, the biologists pinpointed four regions of genetic code that help tell the mice what kind of burrow to construct.


Aerospace


Launch, Then Inflate



Uncredited/Bigelow Aerospace, via Associated Press



NASA signed a contract for an inflatable space habitat — roughly pineapple-shaped, with walls of floppy cloth — that will ideally be appended to the International Space Station in 2015. NASA aims to use the pod to test inflatable technology in space, but the company that builds these things, Bigelow Aerospace, has bigger ambitions: think of a 12-person apartment and laboratory in the sky, with two months’ rent at north of $26 million.


Biology


What’s Green and Flies?



Jodi Rowley/Australian Museum



National Geographic reported on an Australian researcher working in Vietnam who discovered a great-looking new species of flying frog. Described as having flappy forearms (the better for gliding), the three-and-a-half-inch-long frog likes to “parachute” from tree to tree, Jodi Rowley, an amphibian biologist at the Australian Museum in Sydney, told the magazine. She named it Helen’s Flying Frog, for her mother.


Privacy


That’s Joe’s DNA!


People who volunteer their genetic information for the betterment of science — and are assured anonymity — may find that their privacy is not a slam dunk. A researcher who set out to crack the identities of a few men whose genomes appeared in a public database was able to do so using genealogical Web sites (where people upload parts of their genomes to try to find relatives) as well as some simple search tools. He was trying to test the database’s security, but even he did not expect it to be so easy.


Genetics


An On/Off Switch for Disease


Geneticists have long puzzled over what it is that activates a disease in one person but not in another — even in identical twins. Now researchers from Johns Hopkins and the Karolinska Institute in Sweden who studied people with rheumatoid arthritis have identified a pattern of chemical tags that tell genes whether to turn on or not. In rheumatoid arthritis, the immune system attacks the body, and it is thought the tags enable the attack.


Planetary Science


That Red Planet


Everybody loves Mars, and we’re all secretly hoping that NASA’s plucky little rover finds evidence of life there. Meanwhile, a separate NASA craft — the Mars Reconnaissance Orbiter, which has been looping the planet since 2006 — took some pictures of a huge crater that looks as if it once held a lake fed by groundwater. It is too soon to say if the lake held living things, but NASA’s news release did include the happy phrase “clues to subsurface habitability.”


COMING UP


Animal Testing


Retiring Chimps



Emily Wabitsch/European Pressphoto Agency



A lot of people have strong feelings about the use of chimpanzees in biomedical and behavioral experiments, and the National Institutes of Health has been listening. On Tuesday, the agency is to release its recommendations for curtailing chimp research in a big way. This will be but a single step in a long process and it will apply only to the chimps the agency owns, but it may well stir big reactions from many constituencies.

Bank of Japan sets 2% inflation plan









TOKYO — Bowing to government pressure, Japan's central bank Tuesday pledged more aggressive action to boost the economy, including setting a 2% inflation target.

The Bank of Japan said it would conduct "open-ended" asset purchases to help achieve the goal of breaking out of a long spell of deflation.

Prime Minister Shinzo Abe had urged the central bank to ease monetary policy further to help the recession-struck economy escape from years of falling prices.








Whether the effort will succeed remains to be seen: the central bank has not achieved even its 1% inflation target, with price increases hovering below 0.5% for the past two years despite surges in energy costs.

The central bank described its inflation goal as a "price stability target."

"Under the price stability target, the bank will pursue monetary easing and aim to achieve this target at the earliest possible time," it said.

But it said it also would "ascertain whether there is any significant risk to the sustainability of economic growth, including from the accumulation of financial imbalances."

Among the risks are a ballooning public debt, already well over twice the size of Japan's gross domestic product.

Abe's government is seeking to spur growth both through heavy government spending on public works and other projects and through monetary easing. The announcement by the central bank Tuesday was in line with expectations.

The government was determined that the central bank set a 2% inflation target, trade minister Toshimitsu Motegi told reporters on Monday.

"We want a clear inflation target to aim for," Motegi said. "Other countries have inflation targets, and it's not just 1 percent. They are all at least 2%," he said.

Motegi said the monetary easing, which has involved tens of trillions of yen (hundreds of billions of dollars) in asset purchases and years of near-zero interest rates, so far has been "inadequate."

The Abe government is expected to nominate as Bank of Japan governor an expert known to favor its policies when the term of the current governor, Masaaki Shirakawa, ends this spring.

However, Motegi rejected accusations that the government's demands are meant to erode the central bank's independent status.

"We are not doing this to gang up and pick on Mr. Shirakawa," he said. But he said that "the policy of aiming to escape deflation will not change, not today, not tomorrow or the day after tomorrow."

Critics of the government's strategy of pushing for more inflation argue that it will do little to stimulate real demand in the economy if it pushes up prices without accompanying gains in purchasing power.

Clara Jane Nixon dies at 93; sister-in-law of President Nixon









Her famous brother-in-law had not yet been elected president. But he already had been vice president, as well as a U.S. senator and a congressman from California, and Clara Jane Nixon wanted to preserve some of his family history.


So, beginning in 1967, the Newport Beach homemaker set out to track down and collect the furniture, books and other belongings that had filled the modest boyhood home of Richard M. Nixon. She hoped that one day the artifacts might be displayed in a museum.


With the help of other family members, the wife of F. Donald Nixon, a brother of the future president, found and preserved hundreds of items from his childhood home in Yorba Linda, including the piano on which he took lessons, the table where his family ate its meals and the china and crystal his parents received as wedding gifts.





PHOTOS: Notable deaths of 2012


She found the high chair he used as a toddler, the bed on which he was born and the quilt, dating from 1875, that had been used to cover it. The furnishings and other belongings of the Nixon family are displayed in the 900-square-foot farmhouse, a museum near the Richard Nixon Presidential Library in Yorba Linda.


"Clara Jane was just essential to all those artifacts being saved," her brother-in-law Ed Nixon said in a phone interview Sunday. "We're very thankful she was there all these years and for everything she did to preserve the family history."


Clara Jane Nixon died Thursday at a convalescent facility in Irvine where she was receiving care after a recent fall at the home where she had moved after her husband's death in 1987, family members said. She was 93.


She was born Clara Jane Lemke on Nov. 16, 1919, in Westmoreland, a community in Imperial County where her parents were homesteading. She weighed in at less than five pounds, according to the scale — normally used for weighing chickens — that her father employed for the task, her daughter LawreneAnfinson said in a phone interview.


She grew up in Placentia, where her parents, Lawrence and Mae Lemke, were citrus farmers. After graduating from Fullerton High School, she attended Sawyer Business College in Westwood and later worked as a secretary at a law firm.


In 1940, when she was 20, she was introduced to F. Donald Nixon, who was her third cousin on her mother's side. They dated for just three weeks before he asked for her hand, and they were married on Aug. 9, 1942. They had three children: daughter Lawrene, who was named for her grandfather Lawrence, and sons Donald and Richard.


Their son Richard Calvert Nixon died in 2002. In addition to her daughter and her son Donald, Clara Nixon's survivors include six grandchildren and eight great-grandchildren.


In later years, after President Nixon resigned in disgrace on Aug. 9, 1974, his youngest brother was often asked about the significance of the date.


"Whenever anyone asked me, I would say, 'Well, it was Don's and Clara Jane's 32nd anniversary,'" Ed Nixon said.

RIM heats up as BlackBerry 10 launch nears







Research In Motion (RIMM) shares are soaring ahead of the imminent launch of the firm’s next-generation BlackBerry 10 platform. The stock’s recent run could come screeching to a halt at any moment as short interest grows, but Jefferies & Company analyst Peter Misek thinks there’s plenty more good news ahead for RIM. In a note to investors on Friday morning, Misek told clients to buy RIM stock and set a new 12-month price target of $ 19.50, up from his previous $ 13 target with a Hold rating.


[More from BGR: Samsung’s latest monster smartphone will reportedly have a 5.8-inch screen]






“Our checks indicate that the carriers have agreed to volume commitments for the first two quarters post-launch,” Misek wrote. He also notes that “BB10 builds have been raised from 500K/month in early Dec to 1M-2M/month,” and “Developers are supporting BB10 more than we expected. RIM is targeting 70K BB10 apps available at launch.”


[More from BGR: Cable companies called ‘monopolies that stifle competition and innovation’]


Misek says that RIM’s next-generation platform will enable secure corporate email services on iOS and Android devices and the market has overlooked this major change so far. The analyst believes RIM’s March- and August-quarter results will beat Wall Street’s current consensus now that RIM’s huge installed base will finally have a “legitimate upgrade opportunity.”

ABC News' Barbara Walters hospitalized after fall


NEW YORK (AP) — Veteran ABC newswoman Barbara Walters has fallen at an inauguration party at an ambassador's home in Washington and has been hospitalized.


Walters, 83, fell Saturday night on a step at the residence of Britain's ambassador to the United States, Peter Westmacott, ABC News spokesman Jeffrey Schneider said. The fall left Walters with a cut on her forehead, he said.


Walters, out of an abundance of caution, went to a hospital for treatment of the cut and for a full examination, Schneider said on Sunday. She was alert and was "telling everyone what to do, which we all take as a very positive sign," he said.


It was unclear when Walters might be released from the hospital, which ABC didn't identify.


Walters was TV news' first female superstar, making headlines in 1976 as a network anchor with an unprecedented $1 million annual salary. During more than three decades at ABC, and before that at NBC, her exclusive interviews with rulers, royalty and entertainers have brought her celebrity status. In 1997, she created "The View," a live weekday talk show that became an unexpected hit.


Walters had heart surgery in May 2010 but returned to active duty on "The View" that September, declaring, "I'm fine!"


Even in her ninth decade, Walters continues to keep a busy schedule, including appearances on "The View," prime-time interviews and her annual special, "10 Most Fascinating People," on which, in December, she asked New Jersey Gov. Chris Christie if he considered himself fit enough to be president someday. (Christie, although acknowledging he is "more than a little" overweight, replied he would be up to the job.)


Last June, Walters apologized for trying to help a former aide to Syrian President Bashar Assad land a job or get into college in the United States. She acknowledged the conflict in trying to help Sheherazad Jaafari, daughter of the Syrian ambassador to the United States and a one-time press aide to Assad. Jaafari helped Walters land an interview with the Syrian president that aired in December 2011.


Walters said she realized the help she offered Jaafari was a conflict and said, "I regret that."

Well: A Check on Physicals

“Go Beyond Your Father’s Annual Physical. Live Longer, Feel Better”

This sales pitch for the Princeton Longevity Center’s “comprehensive exam” promises, for $5,300, to take “your health beyond the annual physical.” But it is far from certain whether this all-day checkup, and others less inclusive, make a meaningful difference to health or merely provide reassurance to the worried well.

Among physicians, researchers and insurers, there is an ongoing debate as to whether regular checkups really reduce the chances of becoming seriously ill or dying of an illness that would have been treatable had it been detected sooner.

No one questions the importance of regular exams for well babies, children and pregnant women, and the protective value of specific exams, like a Pap smear for sexually active women and a colonoscopy for people over 50. But arguments against the annual physical for all adults have been fueled by a growing number of studies that failed to find a medical benefit.

Some experts note that when something seemingly abnormal is picked up during a routine exam, the result is psychological distress for the patient, further testing that may do more harm than good, and increased medical expenses.

“Part of the problem of looking for abnormalities in perfectly well people is that rather a lot of us have them,” Dr. Margaret McCartney, a Scottish physician, wrote in The Daily Mail, a British newspaper. “Most of them won’t do us any harm.”

She cited the medical saga of Brian Mulroney, former prime minister of Canada. A CT scan performed as part of a checkup in 2005 revealed two small lumps in Mr. Mulroney’s lungs. Following surgery, he developed an inflamed pancreas, which landed him in intensive care. He spent six weeks in the hospital, then was readmitted a month later for removal of a cyst on his pancreas caused by the inflammation.

The lumps on his lungs, by the way, were benign. But what if, you may ask, Mr. Mulroney’s lumps had been cancer? Might not the discovery during a routine exam have saved his life?

Logic notwithstanding, the question of benefits versus risks from routine exams can be answered only by well-designed scientific research.

Defining the value of a routine checkup — determining who should get one and how often — is especially important now, because next year the Affordable Care Act will add some 30 million people to the roster of the medically insured, many of whom will be eligible for government-mandated preventive care through an annual exam.

Dr. Ateev Mehrotra of the University of Pittsburgh School of Medicine, who directed a study of annual physicals in 2007, reported that an estimated 44.4 million adults in the United States undergo preventive exams each year. He concluded that if every adult were to receive such an exam, the health care system would be saddled with 145 million more visits every year, consuming 41 percent of all the time primary care doctors spend with patients.

There is already a shortage of such doctors and not nearly enough other health professionals — physician assistants and nurse practitioners — to meet future needs. If you think the wait to see your doctor is too long now, you may want to stock up on some epic novels to keep you occupied in the waiting room in the future.

Few would challenge the axiom that an ounce of prevention is worth a pound of cure. Lacking incontrovertible evidence for the annual physical, this logic has long been used to justify it:

¶ If a thorough exam and conversation about your well-being alerts your doctor to a health problem that is best addressed sooner rather than later, isn’t that better than waiting until the problem becomes too troublesome to ignore?

¶ What if you have a potentially fatal ailment, like heart disease or cancer, that may otherwise be undetected until it is well advanced or incurable?

¶ And wouldn’t it help to uncover risk factors like elevated blood sugar or high cholesterol that could prevent an incipient ailment if they are reversed before causing irreparable damage?

Even if there is no direct medical benefit, many doctors say that having their patients visit once a year helps to maintain a meaningful relationship and alert doctors to changes in patients’ lives that could affect health. It is also an opportunity to give patients needed immunizations and to remind them to get their eyes, teeth and skin checked.

But the long-sacrosanct recommendation that everyone should have an annual physical was challenged yet again recently by researchers at the Nordic Cochrane Center in Copenhagen.

The research team, led by Dr. Lasse T. Krogsboll, analyzed the findings of 14 scientifically designed clinical trials of routine checkups that followed participants for up to 22 years. The team found no benefit to the risk of death or serious illness among seemingly healthy people who had general checkups, compared with people who did not. Their findings were published in November in BMJ (formerly The British Medical Journal).

In introducing their analysis, the Danish team noted that routine exams consist of “combinations of screening tests, few of which have been adequately studied in randomized trials.” Among possible harms from health checks, they listed “overdiagnosis, overtreatment, distress or injury from invasive follow-up tests, distress due to false positive test results, false reassurance due to false negative test results, adverse psychosocial effects due to labeling, and difficulties with getting insurance.”

Furthermore, they wrote, “general health checks are likely to be expensive and may result in lost opportunities to improve other areas of health care.”

In summarizing their results, the team said, “We did not find an effect on total or cause-specific mortality from general health checks in adult populations unselected for risk factors or disease. For the causes of death most likely to be influenced by health checks, cardiovascular mortality and cancer mortality, there were no reductions either.”

What, then, should people do to monitor their health?

Whenever you see your doctor, for any reason, make sure your blood pressure is checked. If a year or more has elapsed since your last blood test, get a new one.

Keep immunizations up to date, and get the screening tests specifically recommended based on your age, gender and known risk factors, including your family and personal medical history.

And if you develop a symptom, like unexplained pain, shortness of breath, digestive problems, a lump, a skin lesion that doesn’t heal, or unusual fatigue or depression, consult your doctor without delay. Seek further help if the initial diagnosis and treatment fails to bring relief.
