Overall tobacco use among U.S. adults is in decline, reports the Centers for Disease Control and Prevention. Though almost 1 in 5 people still use cigarettes, cigars, pipes or smokeless tobacco, that's a far cry from 1965, when the rate of use was 42%.

Electronic cigarette use, however, is rising, especially among youth. In 2018, more than 3....Read more

Routine mammograms often reveal calcifications in the breast -- bright white lines snaking through the tissue. While not a sign of cancer, new research suggests they may provide clues to risk of cardiovascular disease.

The white lines are indicators of calcium buildup in the breast's arterial wall, which is different from coronary artery ...Read more

Fat, or adipose, tissue isn't just inert blubber threatening our health and self-esteem; it's a functional part of our bodies, interacting with other organs to boost muscle and brain metabolism.

Like everything else, it loses functionality with age, but new research shows that rigorous, regular exercise can help keep your fat fully functional...Read more

We're wrapping up a second full flu season in the middle of a pandemic, and like 2020-2021, the latest season has proven to be thankfully light, with just 5.2 hospitalizations for the flu per 100,000 people -- the lowest rate in years.

There's "long COVID," defined as cases in which people experience new, returning or ongoing health problems more than four weeks after first being infected with SARS-CoV-2, and there's the longer, lingering, broader effects on just about everybody else.

In a new study published in Lancet, researchers describe the pandemic's uneven toll. The ...Read more

The COVID-19 pandemic isn't necessarily the cause, but it has revealed a current shortage in epidemiologists -- scientists trained to search for the cause of disease, identify people who are at risk and determine how to control or stop the spread.

A new report surveying health departments in 30 U.S. cities found 177 open positions for ...Read more

Differences in blood types can mean the difference in whether a person qualifies for an organ transplant. If the blood type of the donor organ doesn't match the recipient's, a mismatched transplant likely results in death.

But a new approach uses enzymes to treat donor organs to make them compatible with recipients of any blood type. Right ...Read more

Our minds inevitably slow with age, but there's new evidence that it doesn't necessarily happen as early as once thought -- or feared. In a published study involving 1 million people who took an online cognitive test, older adults took longer to complete the test than younger participants, but their responses were more accurate.

There are a lot of pluses to living in the country, such as open space and fresh air.

Good health, however, may not be one of them. A new CDC report compared working-age Americans who lived in rural or small urban counties with their counterparts living in large urban counties. All were asked to rate their health.

Rural folks rated theirs ...Read more

Researchers ranked 81 countries on how well their health systems provide for the physical and mental well-being of patients at the end of life. Only six countries earned a grade of A while 36 countries scored Ds and Fs.

"Society should also be judged on how well people die," said study author Eric Finkelstein at Duke Global Health Institute. ...Read more

Most American adults over 65 have some mental health coverage through Medicare, but it's far from adequate, according to a recent Commonwealth Fund study that compared U.S. coverage with that of 12 other high-income countries.

Researchers conducted an international survey after the COVID-19 pandemic began. Roughly 21% of older adults in the U...Read more
