TUESDAY, Sept. 29 (HealthDay News) -- If excess weight doesn't
kill you by old age, it could make your life miserable in the form of
chronic health problems and impaired mental fitness.
According to a new study, women who are obese in middle age are almost
80 percent more likely to have multiple health problems by the time they
reach age 70.
"Those who gained weight [in adulthood] actually suffered reduced odds
of healthy survival," said study author Dr. Qi Sun, a research associate
at the Harvard School of Public Health's department of nutrition.
"The key message is that women really need to keep a healthy weight
from early adulthood to midlife to enjoy a healthy and long life," he
added.
Sun added, however, that the women in the study had nonetheless
survived to their eighth decade, meaning they remained healthier than the
general population.
The study findings were published in the Sept. 30 online edition of the
journal BMJ.
Previous research had focused on how excess weight affects survival,
rather than how healthy that survival looks in older adults, said Sun.
The new study is well-timed, given that the U.S. population is not only
aging rapidly but ballooning rapidly. Two-thirds of American adults are
overweight or obese, up from 14.5 percent in 1976, when this study
started.
The study authors analyzed data on 17,065 women participating in the
Nurses' Health Study. Volunteers were, on average, 50 years old when the
study began with no major chronic conditions or major mental or physical
problems.
Twenty years later, only about 10 percent of women had "healthy
survival," and obese women were 79 percent less likely to have healthy
survival than the slim minority.
Overweight as early as age 18 affected healthy survival the most,
although women who were lean in their late teens who later gained weight
still had lower odds of healthy survival, the study found.
Every kilogram (2.2 pounds) of extra weight lowered the odds of healthy
survival by 5 percent, according to the study.
"We typically see this struggle not only in middle age but even as
teenagers. If you struggle as a teenager, you're going to struggle for the
rest of your life," said Eugenio Lopez, a registered nurse with the Texas
A&M Health Science Center Coastal Bend Health Education Center in
Corpus Christi.
And women may be starting out at a disadvantage, Lopez added.
"We typically see more women than men in diabetes programs. Women
outnumber men 4-to-1 or 5-to-1," Lopez said. "They're genetically
predisposed to hold more fatty cells than men are."
"The data is following common sense," added Dr. Mitchell Roslin, chief
of the bariatric surgery program at Lenox Hill Hospital in New York City.
"Why do people die? Of cardiovascular disease and cancer, and women die of
colon and breast cancer. What has been linked to obesity? Breast cancer,
colon cancer and cardiovascular disease."
