More Parents See Benefits of Vaccines, Poll Finds

MONDAY, July 6, 2015 (HealthDay News) — American parents’ views about childhood vaccines became more favorable over the past year, a new poll finds.

During that time, a number of measles and whooping cough outbreaks made headlines across the country, the researchers noted.

“Over the last year, there have been high-profile news stories about outbreaks of vaccine-preventable diseases like measles and whooping cough. These news reports may be influencing how parents perceive childhood vaccines across the country,” Dr. Matthew Davis, director of the University of Michigan C.S. Mott Children’s Hospital National Poll, said in a news release. Davis is also a professor of pediatrics and internal medicine at the University of Michigan Medical School.

“Outbreaks of disease can safely be prevented through childhood vaccination, but there are deeply held convictions about parents’ autonomy and remaining concerns among some parents about vaccine safety,” he said.

The researchers conducted their survey in May. They found that one-third more parents recognize the benefits of vaccines, compared to a year earlier. They also found that one-quarter more parents believed vaccines were safe than did last year. Additionally, one-third more parents than last year supported requirements that children be vaccinated before entering day care and school.

“For a quarter to a third of parents to say that their views on the safety and benefits of vaccines have shifted in just a year’s time is quite remarkable,” added Davis.

About 40 percent of the parents in the poll said they believe the risk of measles for children is higher than it was a year ago. Around 45 percent of parents said the risk is the same. But, 15 percent said the risk of measles is lower than it was a year ago, the researchers said.

Davis said the perception among parents that vaccines are safer and offer more benefits is consistent with their stronger support of school entry requirements for immunizations.

Media coverage may be swaying parents’ opinions, but the impact of those changes won’t truly be seen unless more parents choose to vaccinate their children, Davis concluded.

People With This Eye Color May Have a Greater Risk of Alcoholism

Your eye color may tell you something about your risk for alcohol addiction, according to a surprising new study from researchers at the University of Vermont.

The study, published in the American Journal of Medical Genetics: Neuropsychiatric Genetics (Part B) found that people with light-colored eyes, including blue, green, grey, and brown in the center but lighter around the edges showed a higher frequency of alcohol dependency compared to those with darker eyes. Blue eyes showed the strongest association with alcohol dependency.

Researchers compared the genetic sequences that determine eye color to those linked to alcoholism, and “found that they line up along the same chromosome, in close proximity” which may help explain the association. However, in an interview with Health, the researchers emphasized that they “still don’t know the reason” for the correlation, and that more research is needed, according to first author Arvis Sulovari, a doctoral student in cellular, molecular and biomedical sciences.

Using a clinical and genetic database of more 10,000 people in the U.S. with and without psychiatric illnesses, the researchers were able to identify 1,263 patients of European ancestry with diagnosed alcohol addictions, and then noticed a higher risk among those with light-colored eyes. They then ran their analysis three times over to see if the pattern held true among different age groups, sexes and among people from different parts of the country, ending up with the same results: that “lighter colored eyes had a significantly higher presence,” according to Sulovari.

This could mean that in the future eye color could be used to pinpoint which people are most at risk for alcoholism.

“This is something that may prove useful in the future for other researchers or in clinics when figuring out the cause of alcoholism,” Sulovari says.

“It’s definitely not the silver bullet for solving the problem of alcohol dependency, but it’s a start.”

Researchers have looked into the health risks of blue eyes in the past, with both positive and negative results. While a 2012 study found that people with blue eyes are the least likely to develop vitiligo, a patchy skin condition caused by an autoimmune attack on pigment, another showed a much higher risk of moles, and in turn melanoma, for those with the light eyes.

For now, the researchers consider the link to alcoholism to be preliminary research, and hope to reach stronger conclusions about the complicated dance between socioeconomics, genetics and disease in their continuing studies on mental illness. They’re also hoping it will shed greater light on the issue of alcoholism.

“I think many people don’t realize that there is genetic background to it,” Sulovari explains. “This is a mental illness, not just something that comes from excessive drinking, and there needs to be more of an effort to find out about it.”

Attraction Can Grow With Time Spent Together

MONDAY, July 6, 2015 (HealthDay News) — The best-looking guys usually land the prettiest girls, but knowing people before dating them might help level the romantic playing field.

Some people appear more attractive to a potential mate over time, perhaps because their inner qualities have had a chance to shine, according to a new study published recently in Psychological Science.

“Our results indicate that perceptions of beauty in a romantic partner might change with time, as individuals get to know one another better before they start dating,” said the study’s lead researcher, Lucy Hunt of the University of Texas at Austin.

Over time, factors such as compatibility can make that person appealing in ways that outshine more easily observable characteristics such as physical attractiveness, she said. “Or perhaps another person might actually become more attractive in the eyes of the beholder by virtue of these other factors,” she added in a journal news release.

This could help explain why people who start dating soon after they meet are more similar in their level of attractiveness than those who get together after being friends for a while, the study authors explained.

It’s well documented that people tend to date those with similar physical, behavioral and psychological characteristics, the researchers said.

The study authors suggested that spending more time together before starting to date may alter this dynamic, making physical attractiveness less important.

“Having the time to interact with others in diverse settings affords more opportunities to form unique impressions that go beyond one’s initial snap judgments,” said Hunt. “Given that people initiate romantic relationships both with strangers and acquaintances in real life, we were interested in how time might affect how similarly attractive couple members are to one another.”

The researchers examined data from 167 couples in a study of romantic relationships. Sixty-seven couples were dating and 100 were married. Some had been together just three months, while others had logged 53 years. The average relationship was a little less than nine years.

Researchers videotaped the couples as they talked about how their relationship. Trained, independent “coders” used these videos to rate the physical attractiveness of each partner. The ratings were consistent, suggesting there was consensus on the participants’ attractiveness.

The longer the couples had known each other before they started dating, the less likely they were to “match” in their level of attractiveness. Couples who were friends before they became romantically involved were also less likely to be matched on attractiveness than couples who started dating within a month of meeting.

Whether or not couples “matched” in their attractiveness didn’t affect the success of their relationship, the researchers noted.

“There may be more to the old saying than was previously thought: Maybe it’s the case that beauty is partially in the eye of the beholder, especially as time passes,” Hunt said.

Calcium Scan Can Predict Premature Death Risk, Study Says

By Dennis Thompson
HealthDay Reporter

MONDAY, July 6, 2015 (HealthDay News) — A scan of calcium deposits inside your arteries can help doctors deduce how long you’re likely to live, a new study has found.

The test, called a coronary calcium scan, uses a regular CT scan to look for calcium deposits in the three major arteries that carry blood away from the heart, said lead author Leslee Shaw, a professor of cardiology at Emory University in Atlanta.

People with the largest amounts of calcium in their arteries carry an early death risk that’s six times greater than those with no calcium deposits, researchers found in a 15-year study of nearly 10,000 patients.

“If you had no calcium or very small amounts, we were able to track over a very long time that you actually had a very outstanding survival,” Shaw said.

Calcium deposits develop as a response to plaque formation along the artery walls, Shaw said.

These plaques, which are caused by blood cholesterol, build up over time and cause arteries to narrow, leading to heart disease as the heart works harder to pump blood through the body.

If a plaque bursts, a blood clot can form on its surface, blocking blood flow and causing a heart attack, according to the U.S. National Institutes of Health. If the clot breaks free, it can flow into the brain and cause a stroke.

To prevent plaques from bursting, the body tries to harden them by depositing calcium salts over and around them, Shaw said.

Doctors learned in the 1990s that these calcified plaques show up on CT scans, and can be used to determine whether a person is suffering from hardening of the arteries, Shaw said.

Up to now, however, there’s been little evidence showing that a calcium scan can provide a solid assessment of a person’s long-term health risk, the study authors said in background information. Most studies involving these scans have a follow-up of five years or less.

In this new study, doctors referred 9,715 healthy patients in the Nashville area between 1996 and 1999 to a cardiology outreach screening program provided by the military’s Tricare Healthcare System. The patients underwent a calcium scan, and also provided a detailed history of their heart risk factors.

Researchers then tracked the participants for roughly 15 years, taking special note of the 936 patients who died.

Analysis revealed that the risk of premature death steadily increased with the amount of calcium deposits found in a person’s major arteries.

Patients with small levels of arterial calcium had a 68 percent increased overall risk of death, compared to those with no calcium deposits at all. But people with the largest calcium deposits in their arteries had a death risk six times greater than those with no calcium.

“This is not a new test, but these results emphasize the importance of looking at this marker in addition to the traditional risk factors,” said Dr. William Zoghbi, past president of the American College of Cardiology and head of cardiovascular imaging for Houston Methodist Hospital.

Calcium scans are currently used to help doctors determine the best treatment for patients who have no heart symptoms but do have high cholesterol or a family history of heart problems, Zoghbi said. This study confirms their usefulness in that regard, he said.

“Calcium scoring really is the earliest marker in the development of hardening of the arteries in people who have no symptoms,” he said. “The best use is in patients who have no symptoms, but the value of the test is not well known.”

The results of a calcium scan can be reassuring for people with few or no calcium deposits, and can provide people with high calcium levels with added impetus to take better care of themselves, Shaw said.

“It can be a very potent motivator,” she said.

People with many calcium deposits can improve their long-term prospects by eating right, exercising, and taking medication to treat heart risk factors such as high blood pressure, elevated blood cholesterol and type 2 diabetes, Shaw said.

Shaw thinks calcium scans ultimately could become part of a person’s regular physical exam, as common as blood cholesterol tests. They generally cost less than $100, she said.

“I think it’s headed that way,” she said. “We’re kind of on the edge of this becoming more accepted.”

The findings appear in the July 7 issue of Annals of Internal Medicine.

4 Sneaky Things That Can Make You Overeat

Photo: Getty Images

Overeating is tricky. First, you may not even realize you’re doing it. Second, you may not know why you’re eating too much, because some triggers are downright counterintuitive. Here are four sneaky reasons you may be taking in too many surplus calories, and what you can do to stop it.

Fitness food marketing
I think we all know that simply eating a food won’t make us more fit, but a recent study published in the Journal of Marketing Research found that when foods are fitness-branded, some of us may unknowingly eat more and exercise less. In the Penn State study “restrained” eaters (people constantly concerned about their weight) were given identical snacks, one labeled “Trail Mix” and the other labeled “Fitness,” which had a picture of running shoes on the packaging. The study volunteers were asked to pretend they were snacking at home, and were given eight minutes to taste and rate the product. In a second phase of the study, subjects had the opportunity to work out  as vigorously as they wanted to on a stationary bike. Scientists found that unless the food was specifically forbidden by their diet, people who were trying to watch their weight ate more of the fitness snack than the trail mix. And these eaters also didn’t work out as vigorously as those who ate the trail mix, apparently seeing the food as a substitute for exercise.

Solution
In my experience, the best way to deflect the effects of food marketing is to raise your awareness. One analogy I often use with clients is getting out of debt. In that situation, you create a budget, and set a goal of carefully thinking through your purchases, rather than buying things impulsively, or based on emotion. Food can be approached the same way. Before reaching for something, check in with your body to determine if you’re hungry. If you aren’t, think about why you want to eat–are you bored, tired, frustrated, or rebelling against a too strict diet? Once you’re aware of the trigger you can address it head on. And if you are hungry, consciously think through what will allow you to hit what I call the “just right” trifecta–full (but not too full), satisfied, and energized. If a food’s packaging or marketing doesn’t align with your instincts about what your body needs to feel just right, getting derailed by marketing will be easy to avoid.

Drinking alcohol–even “skinny” cocktails
I think most people have experienced a loss of inhibition with alcohol, which in turn affects food choices. Numerous clients have told me that an “ah, screw it” attitude brought on by imbibing led to digging into chips and salsa, or ordering a side of fries or dessert. A new Texas Tech University study, published the journal Obesity, highlights why. Researchers found that alcohol makes women’s brains more sensitive to the smell of food, thus increasing caloric intake. In the study, 35 non-vegetarian, non-smoking healthy weight women were given either alcohol or a saline placebo intravenously prior to eating. The women’s responses to both food and non-food aromas were measured using brain scans before a meal. Scientists found that in those who received alcohol, the brain responded more to food odors, and the majority of this group–two-thirds–ate more at lunch. In short, the potential impact of alcohol on weight goes beyond the calories cocktails themselves provide. And if you typically order “skinny” drinks. the effect may be enhanced. A University of North Texas Health Science Center study found that drinks made with artificial sweetener rather than sugar resulted in an 18% greater increase in blood alcohol concentration.

Solution
If you know that drinking is likely to make you want to eat more, strategize before you take your first sip. If you’re going to a restaurant check out the menu online ahead of time, pre-decide what to order, and stick to it. Ask for a tall glass of water along with your drink to slow your pace, and keep the bread basket or chips out of arm’s reach. If you’re hosting a get together, serve up lots of healthy fare, especially finger foods that pack fewer calories for a larger volume, like cut veggies, shrimp cocktail, olives, popcorn, and fruit. Even if you lose track of exactly how much you’ve eaten over the course of the party, you’ll still be less likely to rack up too many calories.

Getting married
A great deal of research shows that overall marriage is good for your health. But a new European study from University of Basel found that while married couples generally eat healthier, they tend to be less active, and weigh significantly more. The researchers compared marital status to body mass index (BMI), which measures weight in relation to height, in over 10,000 people across nine countries. In every country, couples had higher BMIs than singles–whether men or women. The differences were also small between countries, highlighting the likelihood of the connection, and research in the U.S. has shown a similar pattern. One University of North Carolina-Chapel Hill study found that women who get married in their early 20s gain an average of 24 pounds in the first five years, and men in the same age group gain an average of 30 pounds.

Solution
Whether you’re about to get hitched or you’ve been coupled for some time, you can alter your weight fate. The two biggest rules of thumb: don’t use food as entertainment; and eat for your body’s needs, not your partner’s. Many couples I’ve counseled fall into a rut of using food as their primary way of spending time together–going out to dinner, or for ice cream, ordering pizza, making brunch…Try mixing things up and plan activities that don’t revolve around food (go to a play, art gallery or museum, or do something active, like hiking, biking, or indoor rock climbing), or involve healthy eating (visit a farmer’s market instead of a food court). Also, if your partner is a different size, don’t mimic his or her eating habits. I’ve had numerous clients pack on pounds because they started splitting meals or enjoying equal portions with a partner who had much higher calorie needs. If it’s taco night, and you don’t think you can afford to eat as much as your significant other, turn your tacos into lettuce boats and forgo some of the extras, like cheese and sour cream. Being in a relationship don’t have to mean eating the exact same meals or portions, or even eating at the same time. Bottom line: post-nuptial weight gain typically results from a pattern of overeating. If you can reverse that you can undo the poundage.

Frequent snacking
OK, this one may seem like a no-brainer, but many of my clients snack when they’re not hungry, sometimes because they’ve heard that eating small frequent meals is best for weight loss, and by the end of the day they’ve just simply eaten too much. A new study published in the journal Eating Behaviors found that indeed, snacking in the absence of hunger can cause just as much weight gain as consuming high calorie foods or oversized portions. In the study, researchers offered volunteers a chocolate snack after they’d just eaten as much as they wanted of a similar snack food. Three quarters of the group accepted the second snack even though they should not have felt hungry. Scientists found that those who ate the most tended to be more impulsive, and were more responsive to food rewards. They also had higher BMIs, which suggests that repeated snacking in the absence of hunger is a weight gain culprit.

Solution
I see this pattern often in my practice. When clients submit food journals I ask them to track their level of hunger or fullness both before and after meals and snacks, as well as their thoughts, feelings, mood, and insights. By beginning to pay attention to this, many find that they often eat when not hungry, perhaps because food was offered to them, or because they thought the snack was healthy (e.g. nuts are good for me!). Other common reasons include eating out of habit, because others are eating, or due to an emotional cue, like anxiety. If you find yourself falling into this trap, experiment with what it feels like to allow actual hunger to guide you. You’ll quickly learn how to adjust your portions and meal timing so you are physically hungry every time you eat, a pattern that can result in enjoying your food more, while simultaneously slimming you down.

Virus-Carrying Mosquitoes Spreading to New Regions

MONDAY, July 6, 2015 (HealthDay News) — Mosquitoes typically found in tropical regions are expanding into new areas, including the United States, where they could transmit disease, a new study finds.

Once introduced through major shipping routes, mosquitoes carrying viruses such as dengue and chikungunya spread quickly over land, according to the Oxford University researchers.

The study findings were published recently in the journal eLife.

Using detailed records, including national entomological surveys, the scientists created global distribution maps of two species of dengue- and chikungunya-carrying mosquitoes.

“Given the lack of a vaccine or any antiviral treatment for either virus and the debilitating pain they both cause, knowing where the mosquitoes are spreading to and where they might turn up next is crucial for helping to protect communities,” study first author Moritz Kraemer, a doctoral student in epidemiology at Oxford in England, said in a journal news release.

The tiger mosquito (Aedes albopictus) has rapidly expanded in parts of the United States, southern Europe and China over the past 10 to 15 years, the researchers found.

Cities around the world are especially vulnerable to the spread of the yellow fever mosquito, Aedes aegypti. This insect also carries the other viruses and lays its eggs in containers such as abandoned tires and buckets. Although this mosquito can be found in Brazil, China, Taiwan and the United States, yellow fever infection from a mosquito bite isn’t common in the United States, the researchers noted.

Dengue fever, the world’s most common insect-borne virus, causes 100 million infections every year. And the spread of the chikungunya virus into the Americas has already caused more than 1 million cases of disease, according to the study.

“We have made our data openly available so they can be used straight away to help protect people against these viruses about which we still know so little and have so few defenses,” study lead author Simon Ha said in a journal news release.

When New Doctors ‘Train’ During Surgery, Risks Don’t Rise: Study

MONDAY, July 6, 2015 (HealthDay News) — People undergoing brain or spine surgery are at no greater risk if doctors-in-training — called residents — assist during the operation, a new study suggests.

Researchers found that residents are supervised and their assistance doesn’t increase the risk for complications or death.

“Patients often ask whether a resident is going to be involved in their case, and they’re usually not looking to have more residents involved,” Dr. Mohamad Bydon, a resident in neurosurgery at the Johns Hopkins Hospital in Baltimore, said in a hospital news release. “Some people have a fear of being treated in a hospital that trains doctors.”

To see if there was any basis for the concern, the researchers looked at results of more than 16,000 brain and spine surgeries performed between 2006 and 2012. The information was from the database of the American College of Surgeons National Surgical Quality Improvement Program.

An initial comparison showed that surgeries where a fully trained surgeon operated along with the help of a resident had a complication rate of about 20 percent, compared to a complication rate of 12 percent when residents weren’t involved. The resident-assisted surgeries were also associated with a slightly greater risk of death following surgery.

But when the researchers adjusted the data to take into account the patients’ general health and the severity of their condition, there was no increased risk from having a resident take part in the surgery, according to the study authors.

The study was published recently in the Journal of Neurosurgery.

The researchers said their findings could help doctors reassure their patients about the presence of residents in the operating room. “It allows us to say, ‘Not only do we believe this, but it’s also been shown in a population of patients across the country who undergo neurosurgery that there is no downside,’ ” said study author Dr. Judy Huang in the news release. She is a professor of neurosurgery and director of the neurosurgery residency program at the Johns Hopkins University School of Medicine.

And there are benefits to having a resident assist during surgery, Huang said. “It means that there’s an extra pair of hands, an extra pair of eyes,” she explained.

Having a resident help with surgeries is also crucial for training new doctors. “It’s not just about the physical performance of the procedure. It’s also about the reasoning involved, the understanding of what the pitfalls are and how to avoid complications. And that thought process is something that can only occur in the setting of the operating room when a trainee and a teacher work side by side together,” Huang said.

“When you are in the operating room, you see how senior surgeons approach the simpler cases and how they approach the more complex cases, and it’s really invaluable, because that’s how you learn to one day become a [surgeon] yourself,” Bydon added.

Epilepsy Linked to Risks During Childbirth, Study Finds

By Steven Reinberg
HealthDay Reporter

MONDAY, July 6, 2015 (HealthDay News) — Pregnant women with epilepsy may have more than a higher risk of dying during delivery, a new study suggests.

“Specifically, there were 80 deaths per 100,000 women with epilepsy versus six deaths per 100,000 in women without epilepsy,” said lead researcher Sarah MacDonald, from the department of epidemiology at Harvard T.H. Chan School of Public Health in Boston.

However, although the so-called “relative risk” of death during delivery among women with epilepsy was high, it’s still a rare occurrence, MacDonald stressed.

The researchers also found that the risk of delivery complications was higher among women with epilepsy. “We also found that women with epilepsy were at increased risk for cesarean delivery, prolonged hospital stay, preeclampsia [pregnancy-related high blood pressure], preterm labor and stillbirth,” she said.

Although the study found a link between epilepsy and a higher risk of certain complications or death, it’s important to note that the study wasn’t designed to prove that epilepsy caused those outcomes.

Dr. Jacqueline French, a professor of neurology at the Langone School of Medicine at New York University in New York City and coauthor of an accompanying journal editorial, said, “Epilepsy does increase the risk of death [in delivery].”

However, French said this study leaves a lot of questions unanswered because it doesn’t look at the risk of dying during pregnancy, only during delivery.

“Was the epilepsy the reason they died or some other medical problem?” she said.

French said that the message from this study should not be that women with epilepsy are at risk of dying while giving birth. “That’s a really scary thing to say because we don’t have the answers based on these data,” she said.

“If you have epilepsy, the great likelihood is that you are going to have a healthy, normal pregnancy and delivery,” French added.

The report was published online July 6 in JAMA Neurology.

For the study, MacDonald and colleagues used U.S. medical records from delivery hospitalizations to look at birth outcomes, including maternal death, cesarean delivery, length of hospital stay, preeclampsia, preterm labor and stillbirth among pregnant women from 2007 to 2011.

The study included nearly 4.2 million deliveries, of which more than 14,100 were among women with epilepsy. In the United States, between 0.3 percent and 0.5 percent of all pregnancies occur in women with epilepsy.

The reasons for the increased risk of death and other adverse outcomes aren’t known, MacDonald said.

For example, the researchers didn’t have information on anti-seizure medications the women may have been taking, so they didn’t know if these drugs may have had a part in the increased risk.

“While future work is needed to clarify the particular role of anti-epileptic medication on obstetric risks, our work is meaningful in that it highlights a vulnerable patient population,” MacDonald said.

According to the study, women with epilepsy were more likely to suffer from other medical problems, such as depression, diabetes, kidney disease, mental disorders and alcohol and drug abuse. However, whether these conditions played a part in increasing the risk of death during childbirth isn’t known.

“The study was not designed to determine the role of other medical problems the women had on the increased risks in women with epilepsy,” MacDonald said.

More research is needed to understand why women with epilepsy have an increased risk and to determine what can be done to reduce these adverse outcomes, she said.

But, knowing the higher risk in women with epilepsy independent of the reasons is relevant for clinical practice and pregnancy planning, MacDonald said.

“In the meantime, it may be necessary to consider pregnancies in women with epilepsy as high risk and follow them up accordingly throughout pregnancy,” she said.

Some People Do Age Faster Than Others

By Alan Mozes
HealthDay Reporter

MONDAY, July 6, 2015 (HealthDay News) — Adults who look older than their years may be aging at an accelerated pace, new research suggests.

A study of 38-year-olds in New Zealand found their “biological age” — the state of their organs, immune system, heart health and chromosomes — ranged from as young as 30 to as old as 60.

And the older their biological age, the older they looked, the researchers added.

“We looked at key markers for the integrity and health of different organs in the bodies of relatively young adults, in order to detect how their bodies were actually aging,” said study author Daniel Belsky, an assistant professor of medicine at Duke University’s School of Medicine and Center for Aging, in Durham, N.C.

“What we found is a clear relationship between looking older on the outside and aging faster on the inside,” said Belsky. “And also that it’s possible to measure the kind of aging process in young people that we usually only look for in old people.”

For most young adults, biological age proceeds in sync with chronological age, the international research team found. But genetic and environmental influences can cause your biology to rack up signs of age much faster — or much slower — than your birth date might predict.

The findings were published July 6 in the Proceedings of the National Academy of Sciences.

The study authors noted that by 2050 the population of men and women aged 80 and older will hit 400 million globally, more than triple the current number.

That trend, the researchers said, highlights the importance of finding ways to spot signs of aging early in life, to fashion therapies that can prolong healthy living by preventing the onset of age-related disease.

The study team focused on roughly 1,000 men and women who had been participating in an ongoing New Zealand study since their birth in 1972-1973.

In 2011, the participants, then 38, underwent tests of kidney function, liver function, lung capacity and metabolic and immune system strength. Cholesterol, blood pressure, dental status, eye structure and heart health were also assessed, as was the length of chromosomal caps known as telomeres. Telomeres are known to shorten with age.

The researchers found a variance of up to 30 years in the different participants’ biological age, although all were still free of any age-related disease.

The team conducted a secondary analysis, comparing biomarker information collected in 2011 with information gathered six and 12 years earlier.

That showed that between ages 26 and 38 most participants aged at an equal biological pace. But some were gaining three biological years for every one chronological year. Still others had essentially stopped getting older, as their biological age was essentially on “pause.”

What’s more, the older their biological age, the worse they fared on physical and mental acuity tests.

The fast-agers showed worse balance and poorer
motor coordination, and reported having more trouble with tasks such as climbing stairs or carrying groceries.

“This showed that already early in life we can see symptoms of advanced age in young people, symptoms that correspond to declining physical and cognitive function, long before age-related disease actually develops,” Belsky said.

Dr. Rosanne Leipzig, a professor of geriatric and palliative medicine at Icahn School of Medicine at Mount Sinai in New York City,
described the investigation as a “landmark” effort to better understand the aging process.

“If we can identify why some people have more rapid biological aging, it may be possible to intervene and reduce the risks of complications and diseases related to aging,” said Leipzig, who was not involved in the study.

Belsky said the findings might propel scientists in a new direction. “This can help us as we start to come around to the idea that instead of trying to prevent individual illnesses like heart disease or cancer,” he said, “we need to try to find ways to treat the common cause of all these things: aging.”

The research was funded by the New Zealand Health Research Council, the U.S. National Institute on Aging, the U.K. Medical Research Council, the Jacobs Foundation and the Yad Hanadiv Rothschild Foundation.

How to Choose the Best Haircut, No Matter Your Face Shape
