These days, most adults are overweight, not active, or both. If you could change just one—become active or lose weight—which would be better?
At least for men, being more fit may have a bigger health payoff than losing weight, according to a new study of more than 14,000 well-off middle-aged men who are participating in the Aerobics Center Longitudinal Study. Researchers followed their health, weight, and exercise habits for 11 years. They estimated how physically fit the men were by calculating their metabolic equivalents (METs) from a treadmill test.
Compared with men whose fitness declined over the course of the study, those who maintained their fitness levels reduced their odds of dying from cardiovascular disease or any other cause by about 30%, even if they didn’t lose any excess weight. Those who improved their fitness levels saw a 40% reduction.
Body-mass index (BMI), a measurement that takes weight and height into account, was not associated with mortality. The results were published in the journal Circulation.
What is “fitness”

Good vibrations may work for dancing on the beach or for romance, but they don’t seem to do much to strengthen bones.
Results of a clinical trial published in the Annals of Internal Medicine showed that older women who stood on a vibrating platform for 20 minutes a day experienced just as much bone loss over the course of the year-long trial as women who didn’t use the platform.
The results are a disappointment for older women and men looking to strengthen their bones without exercising, not to mention to the companies that have sprung up to sell whole-body vibration platforms as an easy way to halt osteoporosis, the age-related loss of bone.
The idea behind whole-body vibration makes sense. Like walking, running, and other weight-bearing physical activities, whole-body vibration Read more »

No matter how sick my grandmother got or what her doctors said, she refused to go to the hospital because she thought it was a dangerous place. To some degree, she was right. Although hospitals can be places of healing, hospital stays can have serious downsides, too.
One that has been getting a lot of attention lately is the development of delirium in people who are hospitalized. Delirium is a sudden change in mental status characterized by confusion, disorientation, altered states of consciousness (from hyperalert to unrousable), an inability to focus, and sometimes hallucinations. It’s the most common complication of hospitalization among older people.
We wrote about treating and preventing hospital delirium earlier this year in the Harvard Women’s Health Watch. In the New York Times “The New Old Age” blog, author Susan Seliger vividly describes her 85-year-old mother’s rapid descent into hospital delirium, and tips for preventing it.
Although delirium often recedes, it may have long-lasting aftereffects. Read more »

I was hiking in the woods recently with a group of women friends when something caught my attention. It wasn’t an interesting bird or plant, but the surprising number of “pit stops” my friends needed to make.
Their frequent detours into the bushes struck me because I had just finished working on Better Bladder and Bowel Control, the latest Special Health Report from Harvard Medical School. According to the report, incontinence is the unintended loss of urine or feces that is significant enough to make it difficult to do ordinary activities without frequent trips to the restroom. In the United States, about 32 million men and women have some degree of incontinence. For women, incontinence is a common but rarely discussed result of childbirth and aging—that could explain the pit stops of my hiking friends, who were all mid-life mothers. For men, incontinence is most often a side effect of treatment for prostate disorders.
Many things can go wrong with the complex system that allows us to control urination. Read more »

“To everything there is a season, and a time to every purpose under heaven.”
That oft-quoted passage doesn’t apply just to rending and sewing, weeping and laughing, or gathering stones together. Your body has its own set of “seasons,” many of them following the turn of a complete day. Taking some medications at specific times of the day can help them work better. A new study suggests that blood pressure drugs taken at night might improve blood pressure and prevent more heart attacks and strokes than taking the same medications during the day.
Spanish researchers tested Read more »
