Obesity is a common, chronic disease among many U.S. adults and children, but some states have higher rates than others. US News & World Report factored CDC adult obesity rates into the outlet’s annual state rankings and found that West Virginia is the most obese, with a 40.4% rate. “Obesity is a complex disease involving an excessive amount of body fat,” according to the Mayo Clinic. “Obesity isn’t just a cosmetic concern. It’s a medical problem that increases the risk of other diseases and health problems, such as heart disease, diabetes, high blood pressure and certain cancers.” (Lynch, 5/7)

Newly published research suggests that the sons of women with polycystic ovary syndrome (PCOS) are up to twice as likely to develop obesity as their peers. The study in Cell Reports Medicine used data from cohort research following 467,275 male infants born in Sweden between July 2006 and December 2015. Of those, 9,828 were born to a mother with PCOS — and 147 of those boys were eventually diagnosed with obesity. (Blakemore, 5/7)

Talking on a mobile phone even for a very short time each week can raise the risk of high blood pressure — a major cause of heart attacks and strokes.

Passengers with disabilities have described harrowing problems during air travel, including bungled security screenings, risky transfers onto planes, and lost and damaged wheelchairs. ... The Mobility Aids on Board Improve Lives and Empower All Act, introduced Friday, would require the Transportation Department to publicly report on the type of damage that occurs to wheelchairs and other mobility aids. It would require airline carriers to provide information to passengers to ensure a mobility aid can safely fit on a plane. (Morris, 5/5)

More than six million Americans are living with Alzheimer’s disease — and one in three seniors dies with the disease, according to statistics from the Alzheimer’s Association. With so many different factors — genetics, lifestyle and environment — influencing a person’s risk of developing Alzheimer’s, many doctors are moving away from one-size-fits-all approaches and calling for more individualized treatments.

When Herlda Senhouse looks back — way back — in time, she vividly remembers the smells — the sour tang of the beer she siphoned into bottles on her first job while still in grammar school in the early 1920s and the pervasive rotten egg odor from the paper mill near her childhood home in West Virginia.
