Depression could be prevented with specific daily step count, study finds
Getting a certain number of daily steps has long been known to boost overall health — and now a new study has pinpointed how many you need to keep depression at bay.
A research team led by Bruno Bizzozero-Peroni, PhD, from Universidad de Castilla-La Mancha in Cuenca, Spain, analyzed 33 studies involving 96,173 adults.
In comparing the adults’ daily step counts and rates of depression, they found that people with higher daily step counts tended to have fewer depressive symptoms, according to the study findings, which were published in JAMA Network Open last week.

Getting 5,000 or more steps was linked to reduced depressive symptoms, while a step count of 7,000 or higher was associated with a lower risk of depression, the researchers found.
“Our results showed significant associations between higher numbers of daily steps and fewer depressive symptoms, as well as lower prevalence and risk of depression in the general adult population,” the authors wrote in the findings.
“The objective measurement of daily steps may represent an inclusive and comprehensive approach to public health that has the potential to prevent depression.”
More than 7% of U.S. adults have been diagnosed with depression, with those between 12 and 25 years old most affected, according to data from the National Institute of Mental Health.

Dr. Marc Siegel, clinical professor of medicine at NYU Langone Health and Fox News senior medical analyst, was not involved in the study but commented on the review.
“This is an extensive analysis of over 30 observational studies, so it needs to be followed up with prospective randomized studies,” he told Fox News Digital.
“There is already a vast body of evidence, including this study, that exercise is associated with mood improvement, a natural antidepressant.”
The reason that a higher step count reduces depression isn’t only psychological, the doctor said — it’s also physical.
“Exercise increases the release of the ‘happy hormones’ — dopamine, serotonin and oxytocin,” Siegel added.
“The more sedentary we are, or the more we sit, the more depressed we get.”
Previous studies have found that walking has effects on brain networks that are essential in improving mood, depression and anxiety, according to Dr. Richard A. Bermudes, a psychiatrist and chief medical officer of BrainsWay in Nevada.

“The more sedentary we are, or the more we sit, the more depressed we get,” Bermudes, who was not involved in the study, told Fox News Digital.
“We also know that there is an incremental benefit to walking — every increase of 1,000 steps per day was associated with a 9% lower risk of depression.”

Genetics, psychological factors and social stressors also play a role in depression, he noted.
“However, we know that natural light exposure, general movement and walking in natural settings or nature have positive mood effects.”
Bermudes encourages those struggling with depression to “take it one step at a time.”
“For those with severe depression, try incrementally day after day, increasing by 100 steps each day,” he suggested.
“If you work and are stuck at a desk most days, schedule 15-minute breaks to exercise the brain by taking a walk.”
Walking outside is more beneficial, Bermudes added, as it provides natural light exposure.

Bird flu patient had virus mutations, sparking concern about human spread
The patient in Louisiana who was hospitalized with severe bird flu illness was found to have a mutated version of the virus, the U.S. Centers for Disease Control and Prevention (CDC) announced last week.
The fact that the virus mutated within the patient suggests that it could potentially spread from human to human.
The CDC analyzed samples of the H5N1 virus that were collected from the patient, comparing its genomic sequences to those of infected dairy cows, wild birds, poultry and other animals, the agency stated.
BIRD FLU LEADS TO SEVERE HUMAN ILLNESS AND STATE OF EMERGENCY
“The analysis identified low frequency mutations in the hemagglutinin gene of a sample sequenced from the patient, which were not found in virus sequences from poultry samples collected on the patient’s property, suggesting the changes emerged in the patient after infection,” the CDC said.
“While these low frequency changes are rare in humans, they have been reported in previous cases of A(H5N1) in other countries and most often during severe disease.”
Based on the discovery of these genetic changes in the virus, health officials recommend performing “ongoing genomic surveillance” in people and animals, taking steps to contain bird flu outbreaks among dairy cattle and poultry, and taking steps to prevent transmission when exposed to infected animals or environments.
BIRD FLU CAUSES DEATHS OF CATS AND ZOO ANIMALS AS VIRUS SPREADS IN US
The CDC maintains that the risk to the general public is still low.
“The same mutations were not present in viral genomes sampled from the backyard birds that presumably infected the individual,” Samuel Scarpino, director of AI and life sciences and professor of health sciences at Northeastern University in Boston, confirmed to Fox News Digital.
“Because the mutations were present in the human patient, but not the backyard birds, this suggests that the mutations arose during the course of that individual’s infection.”
Dr. Marc Siegel, clinical professor of medicine at NYU Langone Health and Fox News senior medical analyst, told Fox News Digital, shared his thoughts on the significance of this finding.
“Each human infection represents a spin of the epidemic roulette wheel.”
“It is somewhat concerning that the H5N1 bird flu virus found in the Louisiana patient showed a mutation that allowed it to enter the upper airways more easily in this patient, but this mutation has been seen before,” he told Fox News Digital.
The good news, the doctor noted, is that there have not been any reports of the Louisiana patient transmitting the virus to other humans.
“We know the mutations to look out for in terms of the potential to spread among humans” based on previous research, Siegel said.
“It is important that surveillance among domestic poultry and dairy cattle is extensive,” he added.
Scarpino agreed that while the mutations are “concerning,” they “likely do not represent an increased risk to the public.”
“Similar events — mutations arising during infection that increase risk in humans — occurred with the individual who was infected with H5N1 from wild birds in Canada and have happened a number of times during previous H5N1 outbreaks outside the U.S. and Canada,” he told Fox News Digital.
“To date, it does not appear as though the individual in Louisiana transmitted the infection to other people.”

The doctor cautioned, however, that the more opportunities the virus has to infect people, the more likely similar mutations will occur and spark a “chain of transmission” in humans.

“Each human infection represents a spin of the epidemic roulette wheel,” Scarpino said.
“We need to take active steps to eliminate H5N1 infections in agricultural populations and better understand why so many wild birds continue to be infected.”

Bird flu uptick in US has CDC on alert for pandemic 'red flags': report
The Centers for Disease Control and Prevention (CDC) are keeping a close eye on “red flags” relating to the bird flu and whether the illness might develop into a pandemic, according to a report.
The latest numbers show 66 confirmed human cases of bird flu in the U.S. The CDC is taking a holiday break and will resume updates on human cases on Jan. 3.
“Identifying epidemiologically linked clusters of influenza A(H5N1) human cases might indicate the virus is better able to spread between humans,” a CDC spokesperson told Newsweek. “CDC is searching for genetic changes in circulating viruses that suggest it could better transmit between humans.”
The red flags the CDC is monitoring are outbreaks that are spread from person-to-person and evidence that the virus has mutated, Newsweek reports.
BIRD FLU OUTBREAK EXPANDS, MORE MICHIGAN POULTRY FACILITIES EXPOSED TO VIRUS
Last week, the CDC announced that a patient in Louisiana who was hospitalized with severe bird flu illness was found to have a mutated version of the virus. That case fell into the red flag category, the CDC spokesperson told Newsweek.
“The analysis identified low frequency mutations in the hemagglutinin gene of a sample sequenced from the patient, which were not found in virus sequences from poultry samples collected on the patient’s property, suggesting the changes emerged in the patient after infection,” the CDC said in an announcement on its website.
BIRD FLU PATIENT HAD VIRUS MUTATIONS, SPARKING CONCERN ABOUT HUMAN SPREAD
“While these low frequency changes are rare in humans, they have been reported in previous cases of A(H5N1) in other countries and most often during severe disease,” the agency added.
The CDC did not immediately get back to a Fox News Digital inquiry, but previously stressed there has been no known transmission of the virus from the Louisiana patient to anyone else.
Avian influenza, also known as HPAI, is a highly contagious virus that can be spread in various ways from flock to flock through contact with infected animals, by equipment, and on the clothing and shoes of caretakers, according to the Michigan Department of Agriculture and Rural Development.

State officials confirmed infected flocks in two additional Michigan counties on Monday.
According to the CDC, the public health risk associated with avian influenza remains low. No birds or bird products infected with HPAI will enter the commercial food chain.
