Forecasting rates of overweight

Forecasting rates of overweight
Obesity rates for American adults have stabilized while the rate of childhood and minority obesity is rising, as per a research studyin the journal Medical Decision Making, published by SAGE.

Using a novel simulation approach based on national data from 2000-2004 and validated against 2005-2006 data, the study looked at future projections for the distribution of body mass index in the United States. The research explored statistics for a number of categories of Americans based on gender, age and race, seeking to discover which overweight groups were the most likely to have stable, rising or lower rates of weight.

Projections reveal that obesity rates across all age categories for the adult US population will remain stable for the next 10 years. That positive report, however, is contrasted to less positive projections indicating that the following groups of Americans may have rising rates of overweight:.
  • Black young adults (age 18-39 years).
  • Children mainly boys (ages 6-9).
  • Black children (10 and over).


"The unprecedented rise in obesity among U.S. adults over the past two decades appears to have stabilized and will continue to remain stable over the next 10 years," said author Anirban Basu PhD, University of Chicago School of Medicine. "Levels of obesity, however, remain very high and we're especially concerned with the increase in rates of overweight among 6-9 year-old children particularly boys. As they age they could contribute again to the rise of adult obesity, so addressing these risks in early childhood is of utmost importance".........

Get Up, Get Out and Go!

Get Up, Get Out and Go!
Local middle students students participate in an activity with a ranger in Cuyahoga Valley National Park.
Getting children involved in finding ways to become more physically active can not only make them more aware of local recreational opportunities, but can even help increase their own physical activity.

That's the result of a study examining the role of seven national parks in contributing to the health of today's youth. The study was conducted by scientists from a variety of disciplines at North Carolina State University and other U.S. universities and funded by the National Park Service.

The scientists developed pilot programs aimed at increasing the awareness of health benefits from participating in recreational activities at national parks and increasing physical activity by park visitors.

Dr. Myron Floyd, professor of parks, recreation and tourism management at NC State, specifically examined the use of Cuyahoga Valley National Park in Ohio by studying area middle-school students.

"We decided early on that engaging the community in activities the park had to offer would be crucial in developing this pilot program," Floyd said. "We had local 6th and 7th graders actually create the tagline to promote the program: Get Up, Get Out and Go! The students also helped us determine what types of activities would get them interested enough to head out to the park".........

Doctors Miss Major Cause of Infertility and Obesity

Doctors Miss Major Cause of Infertility and Obesity
Gail Donnelly's classmates nicknamed her "Knobby" because she was so skinny all her bones seemed to poke out from under her skin. But when Donnelly turned 27, that once knobby frame disappeared under mysteriously ballooning weight. Her diet hadn't changed, she was still walking several miles a day, but she gained 50 pounds in just six months.

Her doctor thought the cause was ovarian cysts. It took ten years and two surgeries before a new doctor accurately diagnosed her with polycystic ovary syndrome (PCOS). It's a serious metabolic disorder and a main causes of hormonally related infertility, yet the disorder remains largely undiagnosed and unknown. About 5 million women in the U.S. are affected by it.

"Women are told they are too fat and aren't taken seriously for a long time," said Andrea Dunaif, M.D., the Charles F. Kettering Professor of Medicine at Northwestern University Feinberg School of Medicine and a doctor at Northwestern Memorial Hospital. "They go to an average of four doctors before they are diagnosed. They have been to physicians who say 'there is nothing wrong with you, don't worry'".

Before she received the news about PCOS, Donnelly, an ordinarily happy person, had sunk into a deep depression and her boyfriend accused her of letting herself go.........

Self-control is contagious

Self-control is contagious
Before patting yourself on the back for resisting that cookie or kicking yourself for giving in to temptation, look around. A new University of Georgia study has revealed that self-control-or the lack thereof-is contagious.

In a just-published series of studies involving hundreds of volunteers, scientists have observed that watching or even thinking about someone with good self-control makes others more likely exert self-control. The scientists observed that the opposite holds, too, so that people with bad self-control influence others negatively. The effect is so powerful, in fact, that seeing the name of someone with good or bad self-control flashing on a screen for just 10 milliseconds changed the behavior of volunteers.

"The take home message of this study is that picking social influences that are positive can improve your self-control," said main author Michelle vanDellen, a visiting assistant professor in the UGA department of psychology. "And by exhibiting self-control, you're helping others around you do the same."

People tend to mimic the behavior of those around them, and characteristics such as smoking, drug use and obesity tend to spread through social networks. But vanDellen's study is believed to be the first to show that self-control is contagious across behaviors. That means that thinking about someone who exercises self-control by regularly exercising, for example, can make your more likely to stick with your financial goals, career goals or anything else that takes self-control on your part.........

10-15% of women may have disordered eating

10-15% of women may have disordered eating
Montreal, December 18, 2009 Several maladaptive eating behaviors, beyond anorexia, can affect women. Indeed, some 10 to 15 percent of women have maladaptive eating behaviours and attitudes as per newly released study from the Universit de Montral and the Douglas Mental Health University Institute reported in the International Journal of Eating Disorders.

"Our results are disquieting," says Lise Gauvin, a professor at the Universit de Montral Department of Social and Preventive Medicine. "Women are exposed to a number of contradictory messages. They are encouraged to lose weight yet also encouraged to eat for the simple pleasure of it".

Some 1,501 women took part in the phone survey on eating disorders and disordered eating. Not one participant was classified as anorexic. The average age of these urban-dwelling participants was 31, the majority of respondents were non-smokers and university graduates.

Dr. Gauvin says the study sheds new light on binge eating and bulimia, which are characterized in part by excessive eating accompanied by feelings of having lost control. "About 13.7 percent of women interviewed for this study reported binge eating one to five days or one to seven times per month," she says, noting 2.5 percent of women reported forcing themselves to vomit, use laxatives, or use diuretics to maintain their weight or shape.........

Added sugar in raisin cereals

Added sugar in raisin cereals
Elevated dental plaque acid is a risk factor that contributes to cavities in children. But eating bran flakes with raisins containing no added sugar does not promote more acid in dental plaque than bran flakes alone, as per new research at the University of Illinois at Chicago.

Some dentists believe sweet, sticky foods such as raisins cause cavities because they are difficult to clear off the tooth surfaces, said Christine Wu, professor and director of cariology research at UIC and lead investigator of the study.

But studies have shown that raisins are rapidly cleared from the surface of the teeth just like apples, bananas and chocolate, she said.

In the study, reported in the journal Pediatric Dentistry, children ages 7 to 11 compared four food groups -- raisins, bran flakes, commercially marketed raisin bran cereal, and a mix of bran flakes with raisins lacking any added sugar.

Sucrose, or table sugar, and sorbitol, a sugar substitute often used in diet foods, were also tested as controls.

Children chewed and swallowed the test foods within two minutes. The acid produced by the plaque bacteria on the surface of their teeth was measured at intervals.

All test foods except the sorbitol solution promoted acid production in dental plaque over 30 minutes, with the largest production between 10 to 15 minutes.........

New weapon in battle of the bulge

New weapon in battle of the bulge
A real possibility does exist for developing a new generation of foods that make people feel full by releasing anti-hunger aromas during chewing, researchers in the Netherlands are reporting after a review of research on that topic. Such foods would fight the global epidemic of obesity with aromas that quench hunger and prevent people from overeating. Their article appears in ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication.

Rianne Ruijschop and his colleagues note that researchers long have tried to develop tasty foods that trigger or boost the feeling of fullness. Until recently, that research focused on food's effects in stomach after people swallow it. Efforts now have expanded to include foods that release hunger-quenching aromas during chewing. Molecules that make up a food's aroma apparently do so by activating areas of the brain that signal fullness.

Their analysis observed that aroma release during chewing does contribute to the feeling of fullness and possibly to consumers' decisions to stop eating. The report cites several possible applications, including developing foods that release more aroma during chewing or developing aromas that have a more powerful effect in triggering feelings of fullness.........

Golden ratios for female facial beauty

Golden ratios  for female facial beauty
eauty is not only in the eye of the beholder but also in the relationship of the eyes and mouth of the beholden. The distance between a woman's eyes and the distance between her eyes and her mouth are key factors in determining how attractive she is to others, as per new psychology research from the University of California, San Diego and the University of Toronto.

Pamela Pallett and Stephen Link of UC San Diego and Kang Lee of the University of Toronto tested the existence of an ideal facial feature arrangement. They successfully identified the optimal relation between the eyes, the mouth and the edge of the face for individual beauty.

In four separate experiments, the scientists asked university students to make paired comparisons of attractiveness between female faces with identical facial features but different eye-mouth distances and different distances between the eyes.

They discovered two "golden ratios," one for length and one for width. Female faces were judged more attractive when the vertical distance between their eyes and the mouth was approximately 36 percent of the face's length, and the horizontal distance between their eyes was approximately 46 percent of the face's width.

Interestingly, these proportions correspond with those of an average face.........

Online Canadian Pharmacy and Competitive Pricing on Medications

Online Canadian Pharmacy and Competitive Pricing on Medications
People who buy prescription drugs often may well be aware of the tremendous rise in the prices of medicines. In 2006, the prices of prescription drugs witnessed an increase of 8.4%. If your prescriptions are not covered under your medical insurance policy, you appears to be contributing a huge amount towards buying drugs. The best way to save some dollars off your medical bills is to buy prescription drugs at an authorized online Canadian pharmacy.

Tips to Save Money on Prescription Drugs at an Online Canadian Pharmacy
Here are some useful tips for consumers to reduce expenses on prescription medications:
  • Comparison shopping is very important whether you are shopping online or offline. When you are shopping online, it becomes very easy to compare rates and terms of various Canadian pharmacies. There can be variation in the prices of different pharmacies due to various factors, such as level of service and quality of the drugs offered. One should not shop on the assumption that if a drugstore sells more affordable products, it will be the best choice for prescription medications.
  • Some pharmacies offer special discounts to senior citizens, provided they are members of recognized organizations. For instance, members of the American Association of Retired Persons (AARP) are charged reduced prices on prescription drugs.
  • One can always buy generic drugs instead of brand names. The reason is that generic prescription drugs and brand names have the same basic composition, but different prices.
  • If one is prescribed two or more medicines, then it appears to be possible to buy a medicine that offers the combined effect of the two. Most physicians prescribe these drugs without any extra charges. This will not only save you money but will make it easy for you to take and memorize a single medicine.
  • Some Canadian pharmacies offer subscriptions through mail order programs to people who have been consuming the same prescription medications for a long time.
  • One may ask the pharmacist if a drug can be bought in a larger dose and be consumed after splitting it into two parts. This may result in saving a lot of money. However, some pills are supposed to be consumed as a whole pill which is due to a special coating on them.

At NorthWestPharmacy.com, one can find Canadian drugs with up to 80% discount compared to local pharmacies. The website lists various products from their discount Canadian pharmacy. Moreover, if a particular medicine is not mentioned on the website, NorthWestPharmacy.com can often source it at its discount Canadian pharmacy pricing for its customers. Just give them a call toll-free and ask........
