What about seniors drinking alcohol? -NIA


Like all adults, older adults should avoid or limit alcohol consumption. In fact, aging can lead to social and physical changes that make older adults more susceptible to alcohol misuse and abuse and more vulnerable to the consequences of alcohol. Alcohol dependence or heavy drinking affects every organ in the body, including the brain.

comprehensive study from the National Institute on Alcohol Abuse and Alcoholism shows that alcohol consumption among older adults, especially women, is on the rise. The researchers also found evidence that certain brain regions show signs of premature aging in alcohol-dependent men and women. In addition, heavy drinking for extended periods of time in older adults may contribute to poor heart health, as shown in this 2016 study. These studies suggest that stopping or limiting the use of alcohol could improve heart health and prevent the accelerated aging seen with heavy alcohol use.

Leisure activities may improve seniors’ longevity – NIH

Eat less; move more; live longer … How many times have you read that on these pages? Now comes the National Institutes of Health with more of the same.

Physical activity is vital for your health. Exercise helps you maintain a healthy weight and prevent chronic diseases ranging from heart disease to diabetes. The Physical Activity Guidelines for Americans recommend that adults get a minimum of 2.5 to 5 hours of moderate-intensity aerobic physical activity each week, or at least half that amount of vigorous-intensity activity.

Previous studies have found that a wide variety of leisure-time physical activities can provide health benefits. But these studies have largely been done in younger adults. And many did not track different levels of various types of activities.

Poor physical function after age 65 associated with future cardiovascular disease – AHA

Link found between physical function and cardiovascular disease risk in older adults, according to new study in the Journal of the American Heart Association

Among people older than age 65 who were assessed using a short physical function test, having lower physical function was independently associated with a greater risk of developing heart attack, heart failure and stroke, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

The Short Physical Performance Battery (SPPB) used in this study is considered a measure of physical function, which includes walking speed, leg strength and balance. This study examined physical function, which is different from physical fitness.

“While traditional cardiovascular disease risk factors such as high blood pressure, high cholesterol, smoking or diabetes are closely linked to cardiovascular disease, particularly in middle-aged people, we also know these factors may not be as predictive in older adults, so we need to identify nontraditional predictors for older adults,” said study senior author Kunihiro Matsushita, M.D., Ph.D., an associate professor in the department of epidemiology at the Johns Hopkins Bloomberg School of Public Health and the Division of Cardiology at the Johns Hopkins School of Medicine in Baltimore. “We found that physical function in older adults predicts future cardiovascular disease beyond traditional heart disease risk factors, regardless of whether an individual has a history of cardiovascular disease.”

How you feel about aging could affect health – AHA

Is age really just a state of mind?

Perhaps not the number, but how we age might be. A growing body of research suggests a person’s mindset – how they feel about growing old – may predict how much longer and how well they live as the years go by.

Several studies over the past 20 years suggest people with more positive attitudes about aging live longer, healthier lives than those with negative perceptions of the aging process. Recently, a large nationwide study of nearly 14,000 adults over age 50 took an even deeper look into the ways in which positive thinking about aging could impact a person’s physical health, health behaviors and psychological well-being.

Published in JAMA Network Open, the study found those with the highest satisfaction with aging had a 43% lower risk of dying from any cause during four years of follow-up compared to those with the lowest satisfaction. People with higher satisfaction also had a reduced risk for chronic conditions such as diabetes, stroke, cancer and heart disease, as well as better cognitive functioning. People with a more positive attitude about growing old also were more likely to engage in frequent physical activity and less likely to have trouble sleeping than their less-satisfied peers. They also were less lonely, less likely to be depressed, more optimistic and had a stronger sense of purpose.

Trade the chair for fresh air—link exists between sitting time and cardio health

Research is adding further weight to the argument that prolonged sitting may be hazardous to your health. An international study surveying more than 100,000 individuals in 21 countries found that people who sat for six to eight hours a day had a 12-13 per cent increased risk for early death and heart disease, while those who sat for more than eight hours daily increased that to a sobering 20 per cent.

The study, co-led by Simon Fraser University health sciences professor Scott Lear and Wei Li of Beijing’s Chinese Academy of Medical Sciences, is published today in the journal Jama Cardiology. Their research followed individuals over an average of 11 years and determined that high amounts of sitting time were associated with increased risk of early death and cardiovascular disease. While sitting was problematic in all countries, it was especially so in low-income and lower-middle-income countries.
 
“The overarching message here is to minimize how much you sit,” says Lear. “If you must sit, getting in more exercise during other times of the day will offset that risk.”

Not surprising, those who sat the most and were the least active had the highest risk—up to 50 per cent—while those who sat the most but were also the most active had a substantially lower risk of about 17 per cent.
 
“For those sitting more than four hours a day, replacing a half hour of sitting with exercise reduced the risk by two per cent,” Lear notes. “With only one in four Canadians meeting the activity guidelines there’s a real opportunity here for people to increase their activity and reduce their chances of early death and heart disease.”
 
The study found a particular association in lower income countries, leading researchers to speculate that it may be because sitting in higher income countries is typically associated with higher socio-economic status and better paying jobs.
 
Clinicians should focus on less sitting and more activity as it’s a low-cost intervention that can have enormous benefit, Lear notes.
 
But while clinicians need to get the message out about countering sitting with activity, individuals need to better assess their lifestyles and take their health seriously, Lear adds. “Our study found that a combination of sitting and inactivity accounted for 8.8 per cent of all deaths, which is close to the contribution of smoking (10.6 per cent in Lear and Li’s study). “It’s a global problem that has a remarkably simple fix. Scheduling time to get out of that chair is a great start.”

Too Much Self-confidence Can Endanger Health of seniors

Older people who overestimate their health go to the doctor less often. This can have serious consequences for their health, for example, when illnesses are detected too late. By contrast, people who think they are sicker than they actually are visit the doctor more often. This is what a new study by Sonja Spitzer from the Institute for Demography at the University of Vienna and Mujaheed Shaikh from the Hertie School in Berlin found based on data from over 80,000 Europeans aged 50 and older. The results were published in The Journal of the Economics of Aging.

Our confidence affects our behavior. People who overestimate their abilities earn more, invest their money differently, and are more likely to be leaders. But they also act riskier, have more accidents, and live less healthy by drinking more alcohol, eating less healthily, and sleeping too little.

Weight-bearing exercises protect against osteoporosis – Study

“As I reported here, after the age of 50 men are as likely to get osteoporosis as prostate cancer. More to the point, older people of both sexes have great vulnerability to it.”

Now comes a new study that explains how weight-bearing exercises affect our bone structure and fight that disease.

funny_skeleton

Osteoporosis affects more than 200 million people worldwide and is a serious public health concern, according to the National Osteoporosis Foundation. Now, Pamela Hinton, associate professor in the Department of Nutrition and Exercise Physiology, has published the first study in men to show that long-term, weight-bearing exercises decrease sclerostin, a protein made in the bone, and increase IGF-1, a hormone associated with bone growth. These changes promote bone formation, increasing bone density. Continue reading

How seniors tolerate fatigue can be mortality indicator

How fatigued certain activities make an older person feel can predict the likelihood death is less than three years away, according to research published in the Journal of Gerontology: Medical Sciences by University of Pittsburgh epidemiologists. It is the first study to establish perceived physical fatigability as an indicator of earlier mortality. Older people who scored the highest in terms of how tired or exhausted they would feel after activities were more than twice as likely to die in the following 2.7 years compared to their counterparts who scored lower. Fatigability was assessed for a range of activities using the novel Pittsburgh Fatigability Scale.

“This is the time of year when people make—and break—New Year’s resolutions to get more physical activity,” said lead author Nancy W. Glynn, Ph.D., associate professor in the Department of Epidemiology at Pitt’s Graduate School of Public Health.

“I hope our findings provide some encouragement to stick with exercise goals. Previous research indicates that getting more physical activity can reduce a person’s fatigability. Our study is the first to link more severe physical fatigability to an earlier death. Conversely, lower scores indicate greater energy and more longevity.”

Mental game – Don’t make yourself feel old

By HealthDay News

People who believe their bodies and minds will break down with age may be creating a self-fulfilling prophecy, a recent study suggests.

Researchers found that older adults with a dim outlook on aging tended to report more physical health symptoms on days when they were stressed out than on less stressful days.

In contrast, people with more of a “golden years” perspective seemed to have some protection against daily stress: They actually reported fewer health problems on days where they felt more stressed than usual.

“We’ve known that there’s a strong relationship between perceived stress and physical health,” said lead researcher Dakota Witzel, a doctoral candidate at Oregon State University’s College of Public Health and Human Sciences, in Corvallis.

Numerous studies have found that when people habitually feel stressed-out they may eat poorly, skip exercise and have long-term consequences like high blood pressure and an increased risk of heart disease.

But the new findings, Witzel said, suggest that a brighter outlook on aging can be a buffer against the physical effects of daily stress.

How to Maintain a Sharp Brain as you age – Harvard

Health Secrets of a SuperAger

Although all of us senior citizens have our ‘moments,’ recent studies have shown that we can retain our mental clarity by following some basic habits of good health.

Harvard Medical School lists a number of habits that can cut into our chances of suffering from dementia in our old age. They include staying physically active, getting enough sleep, not smoking, having good social connections, limiting alcohol to one drink a day, and eating a balanced diet low in saturated and trans fats.

In addition, they point out several health conditions that can impair cognitive skills, including diabetes, high blood pressure, sleep apnea, depression, hypothyroidism, and high LDL (bad) cholesterol. If you suffer from any of these, they recommend that you follow your doctor’s advice.

They list six strategies that Harvard offers to protect and sharpen our memory and our minds.

Poor sleep linked to feeling older and worse outlook on aging – Study

Poor sleep in the over 50s is linked to more negative perceptions of aging, which in turn can impact physical, mental and cognitive health, new research has revealed.

A study led by the University of Exeter found that people who rated their sleep the worst also felt older, and perceived their own physical and mental aging more negatively.

Lead author Serena Sabatini, of the University of Exeter, said: “As we age, we all experience both positive and negative changes in many areas of our lives. However, some people perceive more negative changes than others. As we know that having a negative perception of aging can be detrimental to future physical health, mental health, and cognitive health, an open question in aging research is to understand what makes people more negative about aging. Our research suggests that poor sleepers feel older, and have a more negative perception of their aging. We need to study this further – one explanation could be that a more negative outlook influences both. However, it could be a sign that addressing sleep difficulties could promote a better perception of aging, which could have other health benefits.”

Close older couples have synchronized heart rates – UI Study

As couples grow old together, their interdependence heightens. Often, they become each other’s primary source of physical and emotional support. Long-term marriages have a profound impact on health and well-being, but benefits depend on relationship quality.

Photo by Gustavo Fring on Pexels.com

A new study from the University of Illinois examines the dynamics of long-term relationships through spatial proximity. The researchers find that when partners are close to each other, their heart rates synchronize in complex patterns of interaction.

“Relationship researchers typically ask people how they’re doing and assume they can recall properly and give meaningful answers. But as couples age and have been together for a long time, they laugh when we ask them how satisfied or how committed they are. When they have been married for 30 or 40 years, they feel that indicates commitment in itself,” says Brian Ogolsky, associate professor in the Department of Human Development and Family Studies at the U of I and lead author on the study.

Iron an underrated factor in aging

Aging-US published “Iron: an underrated factor in aging” which reported that iron is an essential element for virtually all living organisms, but its reactivity also makes it potentially harmful. Blocking iron absorption through drugs or natural products extends lifespan.

10 Early signs of Alzheimer’s Disease – Rush

Why it’s important to look beyond memory loss, and which behaviors to watch for. In my experience, everyone over 50 years old is concerned about their memory and cognitive powers.

Your dad just asked the same question he asked — and you answered — a few minutes ago. You realize that it’s not the first time he’s repeated himself or forgotten something you just said. What does this mean? Does he have Alzheimer’s disease?

Memory changes can be scary, both as an older adult experiencing them and as a family member or caregiver noticing them. But it’s important to note that forgetfulness doesn’t necessarily equal Alzheimer’s disease.

“The red flag is if it’s happening on a consistent basis and is paired with a change in the person’s ability to function,” says Magdalena Bednarczyk, MD, a geriatrician at Rush University Medical Center. “When a patient comes to me for an evaluation, it’s usually because family and friends have noticed uncharacteristic or concerning behaviors, not just memory issues.”

Protein for Better Aging – Tufts

Sarcopenia, the gradual loss of muscle mass that can occur with aging, affects 15 percent of people over age 65, and 50 percent of people over age 80. As we lose muscle mass, we lose strength, and if we lose too much, our ability to function suffers. Fortunately, emerging research is shedding new light on the role dietary protein plays in maintaining muscle, functionality, and health as we age.

Some of this gradual, age-associated loss of muscle mass, strength, and function has to do with a decrease in activity, but not all of it. “Like many complex syndromes of older adults, many factors contribute to sarcopenia,” says Roger A. Fielding, PhD, director of the Human Nutrition Research Center on Aging (HNRCA) Nutrition, Exercise Physiology and Sarcopenia laboratory. “Decreased physical activity, hormonal changes, increase in low-grade inflammatory processes, and changes in dietary intake that include decline in protein intake are all involved.”

Protein and Muscle: The body’s ability to manufacture muscle from protein decreases a bit with aging, so increasing dietary protein—in concert with muscle-building exercise—could help to maintain muscle mass and strength. “We know that in extreme conditions of protein malnutrition people lose muscle mass pretty rapidly,” says Fielding. “But even in older individuals who are taking in protein around the recommended levels, consuming lower amounts of protein is associated with higher rate of muscle loss than consuming higher amounts of protein.”

Paul F. Jacques, DSc, a professor at the Friedman School of Nutrition Science and Policy and senior scientist at the HNRCA Nutritional Epidemiology Team, and his colleagues found higher protein intake may translate to less frailty, disability, or physical dysfunction “We found that higher protein intake was associated with a 30 percent lower risk of losing functional integrity with time,” says Jacques. “This is observational data, but it clearly demonstrates the potential importance of a higher protein diet.”

Experimental drug shows potential against Alzheimer’s disease

Researchers have designed an experimental drug that reversed key symptoms of Alzheimer’s disease in mice. The drug works by reinvigorating a cellular cleaning mechanism that gets rid of unwanted proteins by digesting and recycling them.

Researchers at Albert Einstein College of Medicine have designed an experimental drug that reversed key symptoms of Alzheimer’s disease in mice. The drug works by reinvigorating a cellular cleaning mechanism that gets rid of unwanted proteins by digesting and recycling them. The study was published online today in the journal Cell.

“Discoveries in mice don’t always translate to humans, especially in Alzheimer’s disease,” said co-study leader Ana Maria Cuervo, M.D., Ph.D., the Robert and Renée Belfer Chair for the Study of Neurodegenerative Diseases, professor of developmental and molecular biology, and co-director of the Institute for Aging Research at Einstein. “But we were encouraged to find in our study that the drop-off in cellular cleaning that contributes to Alzheimer’s in mice also occurs in people with the disease, suggesting that our drug may also work in humans.” In the 1990s, Dr. Cuervo discovered the existence of this cell-cleaning process, known as chaperone-mediated autophagy (CMA) and has published 200 papers on its role in health and disease.

CMA becomes less efficient as people age, increasing the risk that unwanted proteins will accumulate into insoluble clumps that damage cells. In fact, Alzheimer’s and all other neurodegenerative diseases are characterized by the presence of toxic protein aggregates in patients’ brains. The Cell paper reveals a dynamic interplay between CMA and Alzheimer’s disease, with loss of CMA in neurons contributing to Alzheimer’s and vice versa. The findings suggest that drugs for revving up CMA may offer hope for treating neurodegenerative diseases.
