Some People Would Give Life Or Limb Not To Be Fat

Some People Would Give Life Or Limb Not To Be Fat
Nearly half of the people responding to an online survey about obesity said they would give up a year of their life rather than be fat, as per a research studyby the Rudd Center for Food Policy and Obesity at Yale.

The 4,000 respondents in varying numbers between 15% and 30% also said they would rather walk away from their marriage, give up the possibility of having children, be depressed, or become alcoholic rather than be obese. Five percent and four percent, respectively, said they would rather lose a limb or be blind than be overweight.

"We were surprised by the sheer number of people who reported they would be willing to make major sacrifices to avoid being obese. It drives home the message that weight bias is powerful and pervasive," said Marlene Schwartz, associate director of the Rudd Center and lead author of the study in Obesity, which was issued this month.

In addition to these comments, the study assessed implicit and explicit, or unconscious and conscious, negative attitudes about obesity. The data was collected from a web site developed for the purpose of the study. People found out about the website by attending a conference, reading articles in which one of the authors was interviewed, or by visiting the Rudd Center website. Of those who responded, three percent were underweight, 41 percent were normal weight, 21 percent were overweight, 21 percent were obese and 14 percent were extremely obese.........

Cultural Approach To Tackling Obesity

Cultural Approach To Tackling Obesity
Culture plays a significant role in how women perceive obesity in terms of both appearance and health, as per a research studyby Yale School of Nursing scientists in the Journal of Advanced Nursing.

Maryanne Davidson, Yale University School of Nursing, and Kathleen Knafl, Oregon Health and Sciences University, reviewed 20 papers published over 10 years on descriptions of the concept of obesity by health professionals, Black Americans, Latino Americans and Caucasian Americans. Davidson and Knafl found women in general base their ideal weight on cultural criteria.

"Black American study participants defined obesity in positive terms, relating it to attractiveness, sexual desirability, body image, strength or goodness, self esteem and social acceptability," said Davidson. "They didn't view obesity as cause for concern when it came to their health."

White women, conversely, defined obesity in negative terms, describing it as unattractive and socially undesirable and associated obesity with negative body image and decreased self-esteem. Davidson said some of these women saw weight as a health issue, while others did not.

"Key health issues correlation to obesity include diabetes, hypertension and cholesterol, asthma and some cancers," Davidson said. "That's why it's imperative that scientists and healthcare providers understand how people from different cultures view obesity. This will help them to promote key messages about the health risks associated with excess weight in a culturally sensitive way."........

Exercise, Diet May Protect Against Colorectal Cancer

Exercise, Diet May Protect Against Colorectal Cancer
Voluntary exercise and a restricted diet reduced the number and size of pre-malignant polyps in the intestines of male mice and improved survival, as per a research studyby a University of Wisconsin-Madison research published May 13 in the journal Carcinogenesis.

The study is the first to suggest that a "negative energy balance" - produced by increasing the mice's energy output by use of a running wheel, while maintaining a restricted calorie intake - appeared to be the important factor in inhibiting the growth of polyps, which are the forerunners of colorectal tumors, says lead author Lisa H. Colbert, assistant professor in the UW-Madison department of kinesiology.

For the study, Colbert and her co-authors used mice with a genetic mutation that predisposed them to develop intestinal polyps.

"Our studies are relevant for humans in that these mice have a mutation in one of the same genes, APC, that is also mutated in human colon cancer," she explains. "The protective effect of exercise and lower body weight in our mice is consistent with epidemiological evidence in humans that suggests higher levels of activity and lower body weight reduces the risk of colon cancer."

Mutations in the APC gene in humans are responsible for an inherited condition called familial adenomatous polyposis (FAP). This condition affects about one in 10,000-15,000 people worldwide, and 95 percent of those affected develop polyps in the colon that eventually progress into cancer, commonly before age 40.........

Extra Pounds May Lower Mortality Rates In Elderly

Extra Pounds May Lower Mortality Rates In Elderly
If you're more than 80 years old, carrying a few extra pounds might not be such a bad idea. In fact, it may be beneficial.

That's one of the findings from a joint UC Irvine and University of Southern California analysis of body mass index (BMI) and mortality rates from participants of a large-scale study based in a Southern California retirement community.

The analysis found that study participants in their 80s and 90s who were overweight by BMI standards (25 to 29.9 range) had lower mortality rates than those who were in the normal range (18.5 to 24.9). The findings suggest that the BMI scale, which applies to all adults, may not be appropriate for the elderly and should be age-adjusted. This supports other research offering the same conclusion. The study appears in the May 15 issue of the American Journal of Epidemiology.

"We found that what's recommended for everyone else with body mass index measurements isn't necessarily the best for the elderly," says Maria Corrada, an epidemiologist in the UCI School of Medicine who led the analysis effort. "It seems that if you're in your 80s or 90s, you may live even longer if you are a bit overweight by BMI standards".

The study, which is part of the Leisure World Cohort Study at Laguna Woods, Calif., looked at survey data taken from 13,451 residents in the large retirement community in 1981-83 and 1985. The residents, whose average age was 73 at the time of the survey, provided their height and weight at age 21 and at the time of the survey.........

How Exercise Can Protect Against Skin And Bowel Cancers

How Exercise Can Protect Against Skin And Bowel Cancers
Two studies published recently have shown that exercise can protect against skin and bowel cancer, and they have identified new mechanisms that could be responsible for this effect.*

Reported in the journal "Carcinogenesis", one study found that female mice that had 24-hour access to running wheels and were exposed to ultraviolet B light (UVB) took longer to develop skin tumours, developed fewer and smaller tumours, and had decreased amounts of body fat compared to mice that did not have access to running wheels. The second study looked at the development of pre-malignant polyps in the intestines of male mice and discovered that voluntary exercise and a restricted diet reduced the number and size of polyps and improved survival.

Dr Allan Conney, Garbe Professor of Cancer and Leukemia Research and Director of the Susan Lehman Cullman Laboratory for Cancer Research at Rutgers University, New Jersey, USA, is one of the authors of the skin cancer study. He said that programmed cell death (apoptosis), triggered by exercise, might explain why the running wheel mice did better.

"Preliminary indications from follow-up work in the laboratory suggest that voluntary exercise enhances UVB-induced apoptosis in the skin, and that it also enhances apoptosis in UVB-induced tumours. So, eventhough UVB is triggering the development of tumours, exercise is counteracting the effect by stimulating the death of the developing cancer cells.........

Lose weight before getting pregnant

Lose weight before getting pregnant
Doctors should advise overweight moms considering another pregnancy to take off extra weight first because they are at greater risk of having big babies, a new Saint Louis University study finds.

Scientists found that moms who don't lose the weight they gained during the first pregnancy and continue to gain after their first child is born are at risk of having bigger babies than mothers who do not gain weight between pregnancies. A patient's prepregnancy weight remained the strongest predictor for the birth of a large infant in the next pregnancy.

"Our advice to moms is to take off the weight they gained during one pregnancy and not to gain weight between pregnancies," said Robert Blaskiewicz, M.D., professor of obstetrics, gynecology and women's health at Saint Louis University.

Large babies can be more difficult and take longer to deliver than normal weight babies because they are too big to fit easily through the birth canal. Large birth weight also might lead to a cesarean delivery.

"The ideal is to have their weight as close to normal as possible. Weight gain between pregnancies doubles the risk of having a 'large for gestational age' baby."

Dr. Blaskiewicz presented the research, which was conducted in conjunction with the Saint Louis University School of Public Health, at the May meeting of the American College of Obstetricians and Gynecologists.........

Food Marketing And Childhood Obesity

Food Marketing And Childhood Obesity
The Federal Trade Commission and the Department of Health and Human Services today released a report recommending concrete steps that industry can take to change their marketing and other practices to make progress against childhood obesity. The report is a product of last summer's joint FTC/HHS workshop, which provided a forum for industry, consumer, academic, and government stakeholders to examine the role of the private sector in addressing rising childhood obesity rates in the United States. Since 1980, childhood obesity rates have tripled among adolescents and doubled among younger children. Workshop participants acknowledged that a number of factors contribute to childhood obesity, but recognized that regardless of the causes, responsible marketing can play a positive role in improving children's diets and exercise behavior.

"Responsible, industry-generated action and effective self-regulation are critical to addressing the national problem of childhood obesity," said FTC Chairman Deborah Platt Majoras. "The FTC plans to monitor industry efforts closely, and we expect to see real improvements".

"Businesses need to work with mothers, fathers and children to bring America's epidemic of childhood overweight under control,'' said HHS Secretary Mike Leavitt. ``Families can help children to be physically active and to eat right, and business can encourage children to eat nutritious foods in proper portions".........

Social Stress Prompts Hamsters To Overeat

Social Stress Prompts Hamsters To Overeat
Put a mouse or a rat under stress and what does it do? It stops eating. Humans should be so lucky. When people suffer nontraumatic stress they often head for the refrigerator, producing unhealthy extra pounds.

When Syrian hamsters, which are normally solitary, are placed in a group-living situation, they also gain weight. So researchers at the Center for Behavioral Neuroscience at Georgia State University are using hamsters as a model for human stress-induced obesity. They want to begin unraveling the complex factors that lead people to eat when under stress and hope that the information can eventually be used to block appetites under this common scenario.

The study, "Social defeat increases food intake, body mass, and adiposity in Syrian hamsters," by Michelle T. Foster, Matia B. Solomon, Kim L. Huhman and Timothy J. Bartness, Georgia State University, Atlanta, appears in the recent issue of the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology published by The American Physiological Society.

Hamsters similar to humans

In the study, the scientists look at nontraumatic stress -- the stress we experience in everyday life, such as getting stuck in traffic or trying to complete a major project at work. It is distinct from traumatic stress, such as suffering the death of a loved one. Traumatic stress typically dulls the human appetite, said Bartness, the study's senior researcher and an authority on obesity.........

Cutting Calories Can Combat Aging

Cutting Calories Can Combat Aging
A lifelong habit of trimming just a few calories from the daily diet can do more than slim the waistline - a new study shows it may help lessen the effects of aging.

Researchers from the University of Florida's Institute on Aging have found that eating a little less food and exercising a little more over a lifespan can reduce or even reverse aging-related cell and organ damage in rats.

The discovery, described this month in the journal Antioxidants and Redox Signaling, builds on recent research in animals and humans that has shown a more drastic 20 percent to 40 percent cut in calories slows aging damage. The UF findings indicate even small reductions in calories could have big effects on health and shed light on the molecular process responsible for the phenomenon, which until now has been poorly understood.

"This finding suggests that even slight moderation in intake of calories and a moderate exercise program is beneficial to a key organ such as the liver, which shows significant signs of dysfunction in the aging process," said Christiaan Leeuwenburgh, Ph.D., an associate professor of aging and geriatric research at the UF College of Medicine and the paper's senior author.

UF researchers found that feeding rats just 8 percent fewer calories a day and moderately increasing the animals' activity extended their average lifespan and significantly overturned the negative effects of cellular aging on liver function and overall health.........

Did you know?
Exercise can't stop the aging process, but experts at Baylor College of Medicine in Houston say that for the elderly, whether it's weight training, walking, swimming or biking, 30 minutes of exercise three to five times a week is a good prescription for aging."It's never too late to start exercising," said Dr. Robert Roush, an associate professor of medicine-geriatrics at BCM. "Being physically active and exercising regularly can help prevent or delay some diseases and disabilities as people age.".
