A leading medical group is offering testing guidelines for children with autistic behaviors.
The American Academy of Pediatrics Council on Environmental Health emphasized that certain measurements to test for exposure to chemicals are not helpful to guide treatment. The council pointed out that just because a chemical is found in the body doesn't mean it will cause harm.
Exposure to mold both in and out of the home may worsen breathlessness and other symptoms of chronic obstructive pulmonary disease (COPD), new research suggests.
More than 16 million Americans have COPD, according to the American Lung Association. COPD is an umbrella term for chronic lung diseases such as bronchitis and emphysema, which literally take your breath away. COPD flares can be...
In normal times, a sunny day can lift your mood while a stormy one can darken it, but new British research shows that weather had little effect on people's spirits during the pandemic.
"We know that lockdown restrictions, and the resulting impact on social life and the economy, are linked to at least two major negative public health consequences -- a reduction in physical exercise, both i...
Children may have an increased risk of obesity if their mothers were exposed to high levels of air pollution during pregnancy, researchers say.
In a new study, 123 Hispanic mother-infant pairs were enrolled in an ongoing trial in the Los Angeles region. Before pregnancy, about one-third of the mothers were normal weight, one-third were overweight and one-third were obese.
Human-caused global warming is responsible for more than one-third of heat-related deaths worldwide, but the proportion is much higher in certain countries, a new study finds.
Researchers analyzed data gathered between 1991 and 2018 from 732 locations in 43 countries. They concluded that 37% of all heat-related deaths in recent summer periods were attributable to the warming of the planet...
A native South American population that lives a pre-industrial lifestyle may have a slower rate of brain aging than the typical Westerner, a new study finds.
The study focused on the Tsimane population, whose roughly 16,000 members dwell in a remote part of the Bolivian Amazon. They live by farming, hunting, gathering and fishing - a lifestyle devoid of processed food, couch time and stre...
Rising temperatures caused by climate change could trigger a worldwide increase in stillbirths, researchers warn.
The team at the University of Queensland in Australia analyzed 12 studies on the subject. They found that exposure to extremely high temperatures throughout pregnancy appeared to increase risk of stillbirth, particularly late in pregnancy.
Sixty-seven percent of inmates in California prisons who were offered a COVID-19 vaccine have accepted at least one dose, a Stanford University study found.
"This is one of the largest state prison systems in the country, and if it can achieve high vaccination coverage among its incarcerated population, then the federal and other state prisons systems can and should do the same for the mo...
Steaks and burgers could be killing thousands of Americans each year, but in a way most people wouldn't expect -- via air pollution.
That's the conclusion of a new study estimating that airborne particles generated by food production kill nearly 16,000 Americans each year. Pollution related to animal products -- most notably beef -- accounts for 80% of those deaths.
Call it a silver lining of the pandemic: Asthma attacks fell sharply among Black and Hispanic Americans in the months after the coronavirus first surfaced.
The study included nearly 1,200 participants who provided information about their asthma through monthly online, phone or mail questionnaires for 15 months between the first half of 2019 and first half of 2020.
Air pollution isn't hard on the hearts of adults only, suggests a new analysis that found it can raise blood pressure in kids as young as 5.
Children experienced increases in blood pressure if they had short-term exposure to air polluted with coarser particles or long-term exposure to finer airborne particles, and that also happened with long-term exposure to nitrogen dioxide, an air poll...
The risk of dying within five years of a heart attack is notably higher among poor Americans than their wealthier peers, but race also plays a role, a new study reveals.
While Black residents of poor neighborhoods appear to face a higher risk of death than their counterparts in wealthier ZIP codes, poor Black patients are also more likely to die after a heart attack than poor white patien...
Increasing numbers of wildfires are making poor air quality more common throughout the Western United States, according to a new study.
The findings suggest that many cities may soon have trouble meeting air quality standards, said lead author Kai Wilmot, a doctoral student in atmospheric sciences at the University of Utah in Salt Lake City.
The Middle East and North Africa are already among the hottest spots on the planet, but new research warns that if nothing is done to slow climate change there will be life-threatening heat waves with temperatures of 132 Fahrenheit or higher in those regions.
"Our results for a business-as-usual pathway indicate that, especially in the second half of this century, unprecedented super- an...
Kids exposed to air pollution may be at risk for mental illness in early adulthood, a new study suggests.
Researchers found that young adults in Britain who were exposed to higher levels of traffic-related air pollutants during their childhood and teen years were prone to develop symptoms of mental illness later. Nitrogen oxides were a particular problem, the study authors reported.
When wildfires choked the air and turned the skies orange throughout the American West in recent years, they caused a variety of health problems from coughs and runny noses to life-threatening heart attacks and strokes.
But eczema and other skin issues were a result of the wildfires, too, according to researchers from the University of California, San Francisco (UCSF), and the University ...
Eviction bans during the COVID-19 pandemic reduced infection rates not only in people who avoided displacement but also in their communities, according to a new study.
"When it comes to a transmissible disease like COVID-19, no neighborhood is entirely isolated," said study author Alison Hill, assistant professor of biomedical engineering at Johns Hopkins University, in Baltimore.
Living near a Superfund hazardous waste site may shorten your life, new research suggests.
There are thousands of Superfund sites across the United States and they include manufacturing facilities, processing plants, landfills and mines where hazardous waste was dumped, left out in the open or poorly managed, posing a risk to the environment and human health.
New research shows that sunnier regions of the United States have lower COVID-19 death rates than cloudier areas, suggesting that the sun's UV rays might somehow provide some protection against the disease.
The effect is not due to better uptake of the healthy "sunshine vitamin," vitamin D, noted the Scottish research team led by Richard...

Because of the COVID-19 pandemic, scientists thought twice about studying North American bats in their winter habitats. But they've now determined that the risk of humans passing the coronavirus to bats under these conditions was low.
The U.S. Geological Survey (USGS) led the study. It found the risk to be one in 1,000 with no protective measures and one in 3,333 with proper use of per...
Nonsmokers usually try to avoid secondhand smoke, but many kids have no option, and now a new study finds tobacco smoke exposure puts them at higher risk of hospitalization.
Compared to other kids, those exposed to secondhand smoke were more likely to have had an urgent care visit over a one-year period, and to incur higher costs for such visits. They also were nearly twice as likely to b...
Fewer children end up in ERs for asthma attacks if nearby coal-fired power plants are shut down, a new study finds.
"When these power plants close, we see a reduction of somewhere between 12% and 18% in emergency department visits for asthma," said senior researcher Emily Pakhtigian, an assistant professor of public policy at Pennsylvania State University. "When the plants close down, chi...
The greener the neighborhood, the lower the stroke risk, a new study suggests.
Researchers matched images gathered from space to health data from residents to come up with their findings. The work adds to evidence that shows where someone lives affects their health, said study co-author Dr. William Aitken. He is a cardiology fellow at the University of Miami and Jackson Memorial Hospital ...
Winter weather can bring hidden dangers, the most deadly of which can include carbon monoxide poisoning and fires.
As blizzards, tornadoes and severe storms batter the nation and many lose power and heat, the danger of carbon monoxide poisoning and fires from portable generators and other devices increase exponentially, the U.S. Consumer Products Safety Commission (CPSC) warns.
Discriminatory housing practices from nearly a century ago continue to influence a person's risk of suffering a stroke, claims a new study that reveals the legacy of structural racism in the United States.
Researchers found a 1.5% higher rate of stroke within census tracts in Columbus, Ohio, most heavily marked for "redlining," compared to neighborhoods in the city least affected by housi...
Raising chickens in your backyard -- a popular trend during the COVID-19 pandemic -- holds risks that can come home to roost in an unwelcome way.
It's already well known that poultry can spread the salmonella bacteria to human handlers. But chickens cooped up in backyards could also be breeding grounds for viruses that pose an even bigger public health threat, according to Sonia Hernandez...
It's that time of year when flowers and trees bloom freely and pollen makes the lives of many miserable. But new research reveals a hidden risk: It could also make you more vulnerable to COVID-19 infection.
COVID-19 infection rates waxed and waned with pollen counts in 2020, according to tracking data gathered across 31 countries in every corner of the globe.
Limiting global warming to targets proposed in the Paris Agreement could keep tropical regions from reaching temperatures that are beyond human tolerability, a new study projects.
Researchers estimate that if countries are able to cap warming at 1.5 degrees Celsius above pre-industrial levels, the tropics will be spared temperatures that surpass the "survival limit." But life in the worl...
Giving homeless COVID-19 patients a free hotel room for their quarantine and recovery pays huge health dividends for the entire community, according to a new study out of San Francisco.
Only 4% of homeless folks transferred from Zuckerberg San Francisco General Hospital to a participating hotel wound up back in the hospital with worsened COVID-19 symptoms, the researchers said in the repo...
If you suffer the itchy, sneezy, wheezy consequences of seasonal allergies, you're probably painfully aware that pollen season is starting earlier and lasting longer than ever.
It's an upshot of climate change, and new research from Germany offers an explanation for this extended sneezin' season: Pollen is on the move, with early blooming spores now wafting across traditional locales and ...
If you think you can safely exercise without your mask in a gym during the pandemic, two new government reports show you are mistaken.
Coronavirus outbreaks at fitness centers in Chicago and Honolulu last summer were likely the result of exercisers and instructors not wearing masks, researchers from the U.S. Centers for Disease Control and Prevention discovered.
Hungry for good news on the pandemic? One epidemiologist believes Americans might reach herd immunity to the new coronavirus as soon as late spring.
That's the view held by Suzanne Judd, a professor with the school of public health at the University of Alabama (UA) at Birmingham. To come to that conclusion, she reviewed recent research and data from her home state.
