Obesity, but not poor diet and inactivity, linked to higher risk of dementia

Jonathan KantrowitzatHealth News Report – 14 hours ago
A large study that followed more than one million women for nearly two decades has found that obesity in midlife is linked to a greater risk of dementia later in life; however, poor diet and lack of exercise are not. The study is published in the December 18, 2019, online issue of *Neurology®*, the medical journal of the American Academy of Neurology. “Some previous studies have suggested poor diet or a lack of exercise may increase a person’s risk of dementia,” said study author Sarah Floud, PhD, of the Nuffield Department of Population Health at the University of Oxford in the Un… more »

Large study links sustained weight loss to reduced breast cancer risk

Jonathan KantrowitzatHealth News Report – 1 day ago
Results show that higher breast cancer risk from excess body weight can be reversed with weight loss American Cancer Society A large new study finds that women who lost weight after age 50 and kept it off had a lower risk of breast cancer than women whose weight remained stable, helping answer a vexing question in cancer prevention. The reduction in risk increased with the amount of weight lost and was specific to women not using postmenopausal hormones. The study appears in *JNCI*. In the United States, more than two in three adult women are overweight or obese. And while high body… more »

Hydration may affect cognitive function in some older adults

Jonathan KantrowitzatHealth News Report – 6 days ago
Not getting enough water is enough to make you feel sluggish and give you a headache, but a new Penn State study suggests it may also relate to cognitive performance. The researchers investigated whether hydration levels and water intake among older adults was related with their scores on several tests designed to measure cognitive function. They found that among women, lower hydration levels were associated with lower scores on a task designed to measure motor speed, sustained attention, and working memory. They did not find the same result for men. The findings were recently publ… more »

Older adults who ‘train’ for a major operation spend less time in the hospital

Jonathan KantrowitzatHealth News Report – 1 week ago
Older adults who “train” for a major operation by exercising, eating a healthy diet, and practicing stress reduction techniques preoperatively have shorter hospital stays and are more likely to return to their own homes afterward rather than another facility, compared with similar patients who do not participate in preoperative rehabilitation, according to research findings. The new study, which appears as an “article in press” on the *Journal of the American College of Surgeons* website in advance of print, evaluated a home-based program of preoperative rehabilitation–called preh… more »

Playing board games may help protect thinking skills in old age

Jonathan KantrowitzatHealth News Report – 3 weeks ago
People who play games – such as cards and board games – are more likely to stay mentally sharp in later life, a study suggests. Those who regularly played non-digital games scored better on memory and thinking tests in their 70s, the research found. The study also found that a behaviour change in later life could still make a difference. People who increased game playing during their 70s were more likely to maintain certain thinking skills as they grew older. Psychologists at the University of Edinburgh tested more than 1000 people aged 70 for memory, problem solving, thinking spe… more »

Aerobic exercise and heart-healthy diet may slow development of memory problems J

Jonathan KantrowitzatHealth News Report – 3 weeks ago
Cognitive impairment without dementia (CIND), or mild cognitive impairment, is a condition that affects your memory and may put you at risk for Alzheimer’s disease and dementia. According to the U.S. National Library for Medicine, signs of mild cognitive impairment may include frequently losing things, forgetting to go to events and appointments, and having more trouble coming up with words than other people of your age. Some experts believe that risk factors for heart disease also are risk factors for dementia and late-life cognitive decline and dementia. Recently, researchers exa… more »

However, more physical activity and less sedentary time were associated with reduced insulin resistance also in obese children. Published in *Medicine & Science in Sports & Exercise*, the findings are based on the Physical Activity and Nutrition in Children (PANIC) Study carried out in the Universit… more »

Yoga enhances many of the same brain structures and functions that benefit from aerobic exercise

Jonathan KantrowitzatHealth News Report – 6 days ago
Scientists have known for decades that aerobic exercise strengthens the brain and contributes to the growth of new neurons, but few studies have examined how yoga affects the brain. A review of the science finds evidence that yoga enhances many of the same brain structures and functions that benefit from aerobic exercise. The review, published in the journal *Brain Plasticity*, focused on 11 studies of the relationship between yoga practice and brain health. Five of the studies engaged individuals with no background in yoga practice in one or more yoga sessions per week over a peri… more »

Play sports for a healthier brain – Even football, soccer, hockey athletes have healthier brains

Jonathan KantrowitzatHealth News Report – 1 week ago
There have been many headlines in recent years about the potentially negative impacts contact sports can have on athletes’ brains. But a new Northwestern University study shows that, in the absence of injury, athletes across a variety of sports — including football, soccer and hockey — have healthier brains than non-athletes. “No one would argue against the fact that sports lead to better physically fitness, but we don’t always think of brain fitness and sports,” said senior author Nina Kraus, the Hugh Knowles Professor of Communication Sciences and Neurobiology and director of … more »

Being active reduces risk of prostate cancer

Jonathan KantrowitzatHealth News Report – 1 week ago
Prostate cancer is the most common cancer in men in the UK , yet we still don’t know all of its causes. The largest ever study to use genetics as a measurement for physical activity to look at its effect on prostate cancer, reveals that being more active reduces the risk of prostate cancer. Over 140,000 men were included in the study, of which, 80,000 had prostate cancer. This new study, published in the *International Journal of Epidemiology* today [5 December], was led by the University of Bristol and co-funded by World Cancer Research Fund (WCRF) and Cancer Research UK (CRUK). … more »

Moderate intensity physical activity associated with lower risk of diabetes

Jonathan KantrowitzatHealth News Report – 1 week ago
Daily exercise at moderate intensity is associated with beneficial levels of a hormone that may lower risk of diabetes, according to a study published in *Endocrine Connections*. Men who were physically active at moderate intensity for 30 minutes a day, released higher levels of a hormone that reduces appetite and blood sugar levels. These findings may suggest that even lower intensity of daily habitual physical activity could help prevent metabolic diseases such as diabetes. A sedentary lifestyle can lead to metabolic complications such as heart disease, diabetes and obesity, and … more »

Sinuses bothering you? Use those nasal sprays regularly

Jonathan KantrowitzatHealth News Report – 1 day ago
Nasal saline and corticosteroid sprays are pretty standard treatment for individuals battling chronic rhinosinusitis (CRS). They thin out thick mucus buildup and help ease the swelling in the nasal cavity that are the bane of anyone who has battled what physicians often refer to as the asthma of the sinuses. If used consistently and appropriately, these nasal sprays can lessen the need for antibiotics and oral steroids that are needed when symptom severities flare, according to a recent study from Dr. Ahmad Sedaghat, an ear, nose and throat specialist at the University of Cincinnati… more »

Aspirin may no longer be effective as cardiovascular treatment

Jonathan KantrowitzatHealth News Report – 1 week ago
A new paper in *Family Practice*, published by Oxford University Press, found that the widespread use of statins and cancer screening technology may have altered the benefits of aspirin use. Researchers concluded that aspirin no longer provides a net benefit as primary prevention for cardiovascular disease and cancer. Nearly half of adults 70 years and older have reported taking aspirin daily even if they don’t have a history of heart disease or stroke. Overall, an estimated 40% of adults in the United States take aspirin for primary prevention of cardiovascular diseases, making it… more »

Jonathan KantrowitzatHealth News Report – 3 weeks ago
Inhaled cannabis reduces self-reported headache severity by 47.3% and migraine severity by 49.6%, according to a recent study led by Carrie Cuttler, a Washington State University assistant professor of psychology. The study, published online recently in the *Journal of Pain*, is the first to use big data from headache and migraine patients using cannabis in real time. Previous studies have asked patients to recall the effect of cannabis use in the past. There has been one clinical trial indicating that cannabis was better than ibuprofen in alleviating headache, but it used nabilone,… more »

HPV vaccines & vaccine schedules in adolescent girls and boys

Jonathan KantrowitzatHealth News Report – 3 weeks ago
New evidence published in the Cochrane Library today provides further information on the benefits and harms of different human papillomavirus (HPV) vaccines and vaccine schedules in young women and men. HPV is the most common viral infection of the reproductive tract in both women and men globally (WHO 2017). Most people who have sexual contact will be exposed to HPV at some point in their life. In most people, their own immune system will clear the HPV infection. HPV infection can sometimes persist if the immune system does not clear the virus. Persistent infection with some ‘hig… more »

Diet pills, laxatives used for weight control linked with later eating disorder diagnosis

Jonathan KantrowitzatHealth News Report – 3 weeks ago
Among young women without an eating disorder diagnosis, those who use diet pills and laxatives for weight control had higher odds of receiving a subsequent first eating disorder diagnosis within one to three years than those who did not report using these products, according to a new study led by researchers from Harvard T.H. Chan School of Public Health and Boston Children’s Hospital. “We’ve known that diet pills and laxatives when used for weight control can be very harmful substances. We wanted to find out if these products could be a gateway behavior that could lead to an eating… more »

Good sleep patterns offset genetic susceptibility to heart disease and stroke

Jonathan KantrowitzatHealth News Report – 15 hours ago
Getting a good night’s sleep could be beneficial for long-term health. A pioneering new study led by Dr. Lu Qi, director of the Tulane University Obesity Research Center, found that even if people had a high genetic risk of heart disease or stroke, healthy sleep patterns could help offset that risk. The study is published in the *European Heart Journal*. The researchers looked at genetic variations known as SNPs (single nucleotide polymorphisms) that were already known to be linked to the development of heart disease and stroke. They analysed the SNPs from blood samples taken from m… more »

Science underestimated dangerous effects of sleep deprivation

Jonathan KantrowitzatHealth News Report – 3 weeks ago
Michigan State University’s Sleep and Learning Lab has conducted one of the largest sleep studies to date, revealing that sleep deprivation affects us much more than prior theories have suggested. Published in the *Journal of Experimental Psychology: General*, the research is not only one of the largest studies, but also the first to assess how sleep deprivation impacts placekeeping – or, the ability to complete a series of steps without losing one’s place, despite potential interruptions. This study builds on prior research from MSU’s sleep scientists to quantify the effect lack of … more »

Lack of sleep may explain why poor people get more heart disease

Jonathan KantrowitzatHealth News Report – 3 weeks ago
Insufficient sleep is one reason why disadvantaged groups have more heart disease. That’s the finding of a study published today in *Cardiovascular Research*, a journal of the European Society of Cardiology (ESC).1 People with lower socioeconomic status sleep less for a variety of reasons: they may do several jobs, work in shifts, live in noisy environments, and have greater levels of emotional and financial stress. This was the first large population-based study to examine whether lack of sleep could partly explain why poor people have more heart disease. It found that short sleep e… more »

Mindfulness training may help lower blood pressure

Jonathan KantrowitzatHealth News Report – 1 week ago
As the leading cause of death in both the United States and the world, heart disease claims nearly 18 million lives every year, according to the World Health Organization. Many of these deaths are due to hypertension, or abnormally high blood pressure, and could be prevented through medication or lifestyle changes such as healthier eating, weight loss and regular exercise — but behavior change is often challenging. That’s where mindfulness may be useful, says Eric Loucks, an associate professor of epidemiology, behavioral and social sciences, and medicine at Brown University. “We… more »

Early-life exposure to dogs may lessen risk of developing schizophrenia

Jonathan KantrowitzatHealth News Report – 15 hours ago
Ever since humans domesticated the dog, the faithful, obedient and protective animal has provided its owner with companionship and emotional well-being. Now, a study from Johns Hopkins Medicine suggests that being around “man’s best friend” from an early age may have a health benefit as well — lessening the chance of developing schizophrenia as an adult. And while Fido may help prevent that condition, the jury is still out on whether or not there’s any link, positive or negative, between being raised with Fluffy the cat and later developing either schizophrenia or bipolar disorder…. more »
