The prevalence of obesity among adults in the US rises considerably, suggesting that the effects on population health may be even more widespread than previously understood, according to a new study led by a Boston University School of Public Health researcher. Andrew Stokes, assistant professor of global health at BUSPH, and colleagues said their findings “highlight the importance” of considering the previously obese subpopulation when monitoring the obesity epidemic. The researchers expanded the scope of their study to include all US adults who were ever obese as well as the currently obese. They found that fifty point eight percent of American men and fifty one point six percent of American women had experienced obesity as of two thousand thirteen to two thousand fourteen.
The researchers examined data around eight diseases-diabetes, congestive heart failure, coronary heart disease, angina, heart attack, stroke, arthritis, and liver disease-and found that those who had ever experienced obesity were at greater risk than those who had not. They also found that those with a history of obesity who were not currently obese experienced disease risks distinct from people who have no history of obesity. Previous research by Stokes and colleagues has shown the association between excess weight and mortality has been significantly underestimated. That research helped undercut the so-called “obesity paradox” raised by prior studies. Stokes and colleagues found that looking at weight history over a lifetime, instead of a single weight measurement, demonstrated obesity to be associated with an elevated risk of death from cardiovascular disease, cancer, and other causes. They also found the highest risk for death among participants who had significant drops in weight, which the authors said most likely reflected unintentional weight loss caused by illness.
Researchers who tested tap water from around the world found that more than eighty percent of the samples contained microscopic-sized plastic fibers — including from President Trump’s New York City home. The contamination is particularly high in the United States, where ninety four percent of faucet water is affected, including in samples from the U.S. Capitol and the headquarters of the Environmental Protection Agency. According to the study, commissioned by the data journalism website Orb and conducted by researchers at the University of Minnesota, the highest rates of contamination was found in Lebanon and India, while the lowest occurred in Europe, where seventy two percent of samples contained fibers.
Orb said scientists believe that most of the tiny fibers originate from clothes, upholstery and carpets, including particles released by the actions of washing machines and dryers. According to a U.K. study, each cycle of a washing machine could release more than seven hundred thousand microscopic plastic particles, The Guardian reported.According to Orb, such material, known as microplastics, has been shown to absorb toxic chemicals linked to cancer and other illnesses, which are then released when consumed by fish, farm animals and humans.
Government health officials say that progress in preventing stroke deaths in the United States has stalled after forty years of decline, and may even be reversing. Stroke deaths increased significantly among Hispanics and in the South between two thousand thirteen and two thousand fifteen, the U.S. Centers for Disease Control and Prevention reported Wednesday.
“This report is a wake-up call because eighty percent of strokes are preventable,” said lead author Quanhe Yang, a CDC research scientist.
According to prior research, high blood pressure is the most important preventable and treatable risk factor for stroke. But high cholesterol, smoking and physical inactivity play a role, too. While stroke death rates declined thirty eight percent from two thousand to two thousand fifteen, researchers said the average decline fell from nearly seven percent between two thousand three and two thousand six to a three percent drop over the next eight years. Worse than that, from two thousand thirteen to two thousand fifteen, there was a two point five percent annual increase, although researchers call that uptick “nonsignificant.”
Each year, nearly eight hundred thousand people in the United States suffer a stroke, and more than one hundred forty thousand die. And many survivors face long-term disability. According to CDC director Doctor Brenda Fitzgerald, someone in the United States has a stroke every 40 seconds. She added that stroke costs the US thirty four billion dollars annually. Multiple factors have slowed the decline in stroke deaths, Yang noted, including high rates of obesity and diabetes. Stroke is a medical emergency caused by a blockage in an artery leading to the brain or bleeding into the brain. Those symptoms include face drooping, arm weakness or numbness, or speech difficulty.
