Even a little exercise can counter the harms of sitting all day, a new study suggests. Prolonged sitting raises your odds for an early death, but just 20 to 25 minutes of physical activity a day may offset that risk, researchers found. “If people, for any reason, are sedentary for most of the day, small amounts of physical activity will still lower the risk of death substantially,” said lead researcher Edvard Sagelv, from UiT The Arctic University of Norway, in Tromso. That can even include light intensity exercise like cleaning. For the study, Sagelv and his team reviewed data on nearly 12,000 older adults. They found that being sedentary for over 12 hours a day — perhaps either watching TV or sitting at a desk — raised the risk of early death, but only in those getting less than 22 minutes of moderate exercise a day. “Individuals doing more than 22 minutes of moderate-to-vigorous physical activity per day, the equivalent of the World Health Organization’s 150 minutes per week guidelines, had no increased risk of death with more sedentary time,” Sagelv said. This study, however, can’t prove that exercise alone lowered the risk of premature death, only that there appears to be an association. Still, the study “is a reaffirmation of our fundamental need to move our bodies if they are to reward us with… read on > read on >

Getting a certain number of steps each day can help people improve their fitness, but new research shows it also can pay off in the operating room. The odds of complications within 90 days after hospital discharge were reduced by half if a patient was getting more than 7,500 steps a day before their procedure, the study found. These postoperative complications typically occur after a patient returns home. About 30% of patients suffer these problems, which can include infection, blood clots and wound complications. “I think it’s probably more an assessment of an individual’s overall fitness and their health generally,” said study co-author Dr. Anai Kothari, an assistant professor with a specialty in surgical oncology at the Medical College of Wisconsin. “We use a lot of information to try to decide and think through surgical risk. My hope is that this is an additional point of reference that practitioners can use.” Surgeons can already better understand a person’s risk by knowing they have certain health conditions, such as diabetes, Kothari said. Knowing how active that patient is could add information about their risks. What do the results tell doctors? “[The] first is we can actually use wearable devices to give us insight into a domain of their health and fitness that we may previously not have had an opportunity to do. This can be a… read on > read on >

Heated yoga classes can help some people with depression feel a lot better within a couple months — even if they practice just once a week, a small clinical trial suggests. The study, of 65 people with moderate-to-severe depression, found that those randomly assigned to heated yoga classes saw a greater symptom improvement over eight weeks than those assigned to a waitlist. Overall, 16 patients, or 59%, “responded” to the yoga classes — meaning the severity of their depression symptoms dropped by at least half. Only two patients on the waitlist (6%) saw their symptoms improve that much. Beyond that, 12 patients in the yoga group, or 44%, saw their depression go into remission. The findings, published Oct. 23 in the Journal of Clinical Psychiatry, add to evidence that yoga can help people deal with mental health conditions. The twist was the heat. Study participants took class in a room heated to 105 degrees and followed a traditional Bikram yoga sequence — a set of 26 postures that is the same each class. It’s not clear, though, whether the heat was the key ingredient, said lead researcher Maren Nyer, an assistant professor of psychiatry at Harvard Medical School and director of yoga studies at Massachusetts General Hospital. Because the comparison was a waitlist, she said, the benefits could have come from the yoga, the heat… read on > read on >

Use of steroids among high school athletes is a continuing problem, and now new research finds these youths are also more likely to suffer a concussion while they play. The study was published Oct. 20 in the Journal of Osteopathic Medicine. “The neurobehavioral shifts of steroid use may lead to increased aggressive play and a subsequent heightened risk for concussions,” said researcher Kennedy Sherman, of Oklahoma State University College of Osteopathic Medicine at Cherokee Nation. “Moreover, athletes using steroids are likely to have higher muscle volume and increased muscle strength, amplifying the momentum and impact of head-on collisions,” Sherman added in a journal news release. “Steroid use and concussions each have numerous health consequences, and when occurring together in a person, these effects may be amplified.” Researchers used data from a Youth Risk Behavior Surveillance System survey, finding that 3.7% of young athletes reported previous steroid use. About 20.7% of all athletes reported having sustained a concussion. Among those who did not use steroids, nearly 20% reported a concussion, compared to about 55% of those who did use steroids. The good news? The prevalence of steroid use among high school athletes decreased from 3.4% in 1999 to 1.9% in 2019. The highest rates were in 2001 and 2003, at 5.3% and 4.4%, respectively. Use varied across ethnic groups. The highest rate was seen in the… read on > read on >

Kids who get discouraged by idealized athletic bodies on social media may end up dropping out of sports, a small study suggests. In a preliminary study of 70 kids who played — or used to play — sports, researchers found that some had quit because they thought they didn’t have the “right” body for the activity. And most got that idea from media images, including TikTok and Instagram posts. Experts said the findings add to evidence that unrealistic, often “filtered” or “edited,” images on social media can make some kids feel bad about their own bodies. And in the case of kids who play sports, the study suggests, those feelings could translate into action: quitting. That outcome would be “heartbreaking,” said researcher Dr. Cassidy Foley Davelaar, considering all that kids can gain from participating in sports. It benefits their physical health, she said, and helps them form friendships, build confidence and resilience, and more. Sports should “be inclusive of all body sizes and shapes,” said Foley Davelaar, a sports medicine physician at Nemours Children’s Health in Orlando, Fla. She is scheduled to present the findings Sunday at a meeting of the American Academy of Pediatrics, in Washington, D.C. Studies released at meetings are generally considered preliminary until they are published in a peer-reviewed journal. While this study was small, it aligns with other research tying… read on > read on >

Want to do something to protect your thinking skills as you age? Swing that golf club or go for a walk. A new study found that walking about 3.7 miles or playing 18 holes of golf improved cognitive function. Nordic walking, a type of full-body walking using poles, showed the same benefit. “These findings underscore the value of age-appropriate aerobic exercise, such as golf, Nordic walking and regular walking, in maintaining and enhancing cognitive function among older adults,” said first author Julia Kettinen, a doctoral researcher at the University of Eastern Finland. “Previous research has shown that exercise also holds promise as a potential strategy for those experiencing cognitive decline,” she said in a university news release. For the study, 25 healthy golfers age 65 and older participated in three bouts of intense aerobic exercise — golf, walking and Nordic walking — in a real-life environment, maintaining their typical brisk pace. The researchers then assessed cognitive function using a pair of tests that measure functions such as attention, processing speed and demanding skills such as task-switching ability. They also collected blood samples to measure two chemicals — neurotrophic factor (BDNF) and cathepsin B (CTSB) — believed to reflect the benefits of exercise in the brain. Participants wore fitness monitoring devices to monitor their distance, duration, pace, energy expenditure and steps. An ECG sensor with a… read on > read on >

Arthritis is becoming a disease of the masses, striking 21% of U.S. adults, or over 53 million people, a new report shows. “It’s important first to point out that arthritis is a general term that includes over a hundred different chronic diseases that affect the joints and the tissues around those joints,” said researcher Elizabeth Fallon, an epidemiologist for the U.S. Centers for Disease Control and Prevention. The finding was culled from an analysis of data from the National Health Interview Survey from 2019 to 2021. How did the numbers break out? About 88% of all arthritis cases were adults aged 45 and up, while about 50% were working-age people ranging in age from 18 to 64. Additional risk factors included being a woman, being a veteran or having another chronic disease or disability, Fallon said. Although this analysis didn’t look for trends over time, “it’s already a large public health problem,” Fallon noted. “If it’s growing, we need to know that so we can appropriately address it from a public health perspective.” Arthritis is a leading cause of activity limitations and disability, as well as chronic pain. A common thread in the findings was that more than half of folks who had arthritis also had other health conditions. About 58% of people who have COPD have arthritis, as do 56% of those with dementia,… read on > read on >

Pickleball has become wildly popular, but that may be fueling a rise in pickleball-related injuries. “It’s quickly becoming a sport of choice for adults over the age of 50,” said Dr. Brian Cole, an orthopedic surgeon and sports medicine specialist at Rush University Medical Center in Chicago. He also plays pickleball. “The high injury rate can be attributed to the fact that most players tend to be over 50,” Cole said in a hospital news release. “And many of them were largely sedentary before picking up their pickleball paddles.” Pickleball is like a hybrid of ping-pong and tennis, and attracts many beginners. In his practice, Cole often sees strains and sprains, mostly in the legs and ankles. Rotator cuff injuries are also common. Sometimes he sees more serious injuries, including fractures and concussions. Here, Cole offers some pointers on avoiding injury. A good first step to avoid injury is to first get an assessment of your health from your primary care physician and possibly also a physical therapist. You may not be as prepared to jump into play as you think if you haven’t been very active in a while. “Patients over 60 account for nearly 80% of pickleball injuries, and most of them are male,” Cole said. Importantly, many seniors have underlying conditions they don’t know about. “Millions of people walk around with rotator… read on > read on >

Treating shoulder pain with steroid shots or removal of cartilage buildup yields the same result as no treatment at all, a Norwegian research team reports. They said their findings call into question treatment guidelines for calcific tendinopathy, a painful condition in the shoulder’s rotator cuff tendons. Researchers said the common invasive procedure, known as ultrasound-guided lavage, appears to be useless. “The study findings should lead to a critical reconsideration of treatment guidelines for this condition, specifically for the use of ultrasound-guided lavage and cortisone injections,” said lead researcher Dr. Stefan Moosmayer, a consultant orthopedic surgeon at Martina Hansens Hospital in Gjettum, Norway. Calcific tendinopathy is a common shoulder condition marked by calcium buildup. But the study, published Oct. 11 in the journal BMJ, calls into question whether calcium buildup is the true cause of the joint pain. “We over-focus on the calcification itself,” Moosmayer said. “There may be other mechanisms which we have not fully understood.” Calcification has long been assumed to be the source of the pain, and treatments aim to remove it. A widely used method is ultrasound-guided lavage, in which saline is injected into the calcium deposits to help dissolve them. “Benefits from ultrasound-guided lavage or from a steroid injection, however, are no better than from placebo treatment,” Moosmayer said. For the study, 218 patients suffering from shoulder pain were randomly assigned… read on > read on >

Exercise has been dubbed “nature’s antidepressant” by doctors for years, and now a new study confirms the notion. The finding follows a four-month look at the impact that running had on anxiety and depression when compared to a common antidepressant. SSRIs (selective serotonin reuptake inhibitors) work by boosting levels of serotonin, a neurotransmitter that’s a key player when it comes to regulating mood, depression and anxiety. But among 140 depression patients, those who engaged in regular group running — meaning two or three 45-minute runs each week — actually saw their depression levels drop a bit more than those who took the popular SSRI medication escitalopram (Lexapro). And those who treated their depression with exercise reaped an added reward, with improvements seen in their physical health as well. That group, said study author Brenda Penninx, also “lost weight, improved fitness and reduced heart rate and blood pressure.” The medication group did not see those benefits. Penninx, a professor of psychiatric epidemiology and vice chair of the department of psychiatry at Amsterdam University Medical Center in the Netherlands, presented her findings this weekend at the ECNP meeting, which focuses on the science and treatment of brain disorders. The research was published earlier this year in the Journal of Affective Disorders. All told, she said, the findings suggest that “we should pay much more attention to lifestyle… read on > read on >
