More than four in 10 American women are now classified as obese in an alarming new milestone for the nation.

Obesity rates for men and women in the US had been roughly the same for about a decade. But in recent years, women have surged ahead and now just over 40% of women are obese, compared to 35% of men.

The percentages were reported by the Centers for Disease Control and Prevention, in two articles published online on Tuesday by the Journal of the American Medical Association. The numbers are based on a small government survey that is considered the best measure of the nation’s obesity problem.

Though it is not altogether surprising to health researchers because the nation has long been growing more obese, it is “scary” that the statistic has reached 40% for women, said Dana Hunnes, a dietitian who sees obese patients at Ronald Reagan UCLA Medical Center in Los Angeles.

“It’s a really alarming figure, and it’s alarming that it’s continuing to go up despite government calls to action on weight loss and healthy eating,” she said.

Why the problem is getting worse for women faster than for men remains somewhat of a mystery to health researchers. “I don’t know if anyone truly knows for sure,” Hunnes said. Experts say there are a range of possible explanations, including that many women are satisfied with a larger body size.

The rate of obesity in women is also higher than in men across the world, although far lower overall than in the US. According to the World Health Organization, 15% of women worldwide and 11% of men are obese.

Obesity, which means not merely overweight, but seriously overweight, is considered one of the nation’s leading public health problems because it can trigger diabetes and lead to heart disease and other serious health problems. Until the early 1980s, only about one in six adults were obese.

The problem is not increasing as dramatically as it was, but the new numbers show it is clearly not improving, said Dr Felipe Lobelo, an Emory University researcher who focuses on obesity and physical activity.

Researchers looked at obesity rates among different age groups and along racial lines and found wide disparities, mainly ones that have persisted for years.

Obesity continues to be most common among black women. About 57% of black women are obese. In contrast, about 47% of Hispanic women, 38% of white women, and 12% of Asian women are obese.

Among men of different races, obesity rates cluster much closer together — at 35 to 38% for blacks, Hispanics, and whites.

New record links frequency of diet soft drink use to waist increase

Those which drink diet regimen soda thinking it will help them shed unwanted tummy fat may see their waistlines expand rather. New evaluations from an empirical research study of San Antonio males and females age 65 and also older seem to indicate this.

Diet Soda Increases WaistThe San Antonio Longitudinal Research of Growing old (SALSA), led by Helen P. Hazuda, Ph.D., instructor of medicine in the School of Medication at The College of Texas Health Science Facility at San Antonio, gathered information on wellness condition as well as way of livings of 749 Mexican-American and also European-American senior citizens, then tracked the wellness end results in 466 survivors for more than 9 years. The number of sodas they ate – as well as whether they were diet regimen or normal – was recorded by interviews at the start of the research as well as at each of 3 follow-up visits, where SALSA employees determined participants’ waistline circumferences and also other criteria.


Among SALSA individuals who reported that they did not take in any sort of diet sodas, waistline circumference enhanced less than 1 inch on average over the total follow-up period, claimed Sharon P. Fowler, M.P.H., adjunct faculty in the School of Medicine at the Health Scientific research Center. Between participants that stated periodic usage – drinking less than one diet soft drink a day – midsection area increased nearly 2 inches. And also among those which took in diet regimen sodas every day, or a lot more frequently than once daily, midsection circumference increased over 3 inches. With elderly writer Dr. Hazuda as well as co-author Ken Williams, M.S., complement professors in the School of Medicine, Fowler is lead author of a paper explaining the data in the April problem of the Journal of the American Geriatrics Society.

These searchings for raise a warning for seniors considering that body fat around the waist – the proverbial tire around the center – includes not only fatty tissue just under the skin but also body fat that gathers around inner body organs, known as viscera. Numerous research studies have linked visceral fat with enhanced inflammation and also risk of metabolic illness, diabetic issues, cardiac arrest, stroke, cancer and death. When midsections increase in older age, natural body fat increases disproportionately, and risk increases.

“Because Dr. Hazuda’s study measured waist circumference as well as total weight, we were able to look at what happened to participants’ abdominal obesity,” Fowler said. “The increases in abdominal fat were more than three times as great in daily diet soda users as in non-users, during the very time in life when increasing waist circumference is associated with increased risk of these serious medical conditions, and mortality itself.”

Different from previous research study.

The team’s previous related research, released in 2008, looked at the association in between overall consumption of artificially sweetened drinks – soft drink plus coffee plus tea – as well as lasting weight gain between individuals in the San Antonio Heart Study, led by Michael Stern, M.D., emeritus professor in the Institution of Medication. That research discovered that, amongst greater than 3,600 25- to 65-year-old Mexican-Americans as well as European-Americans complied with for seven to 8 years, physical body mass index as well as danger of excessive weight rose constantly with boosts in artificially sweetened refreshment intake.

In the existing SALSA guide, the scientists adjusted statistically for a multitude of variables that might have affected the searchings for, consisting of initial midsection size, exercise level as well as whether the individual had diabetic issues or smoked. “Even when you adjust for those things, you have this independent effect of diet soda consumption on waist circumference change over time,” Dr. Hazuda said.

“There is definitely debate about whether the association between diet soda intake and cardiometabolic risk, which has been detected in several large observational studies, is based on an actual causal relationship,” Fowler said. “We are simply reporting the statistical association we found: that, over almost a decade, waist circumference increased significantly, in a dose-response manner, with increasing diet soda intake in this group of older individuals. These results are consistent with findings from a number of other observational studies of increased long-term risk of diabetes, heart attack, stroke and other major medical problems among daily diet soda users.”

Although the study friend is relatively tiny, with 466 people, the outcomes were based on 3,706 person-years of follow-up. The searchings for were in people age 65 and also older; whether they would apply to more youthful folks is not known. The findings were additionally most obvious among those which were currently over weight or obese at the outset of SALSA. It is an empirical research instead of a randomized, managed test design, which is the gold standard in clinical epidemiology.

“In spite of these limitations, however, the evidence, taken together with relevant findings from other studies in both humans and animals, is pretty compelling,” Dr. Hazuda said. “We’re trying to provide the evidence base for meaningful decision-making to improve both the health of individuals, and the public health.”
