Major study examines meat-diabetes link

People who increased their consumption of red meat during a four-year period were more likely to develop Type 2 diabetes in a subsequent four-year period, according to an analysis involving about 150,000 people. The analysis, led by researchers at the National University of Singapore, took data from three long-running Harvard University studies involving mostly nurses and doctors. The results were published online Monday in JAMA Internal Medicine, a journal of the American Medical Association. The studies were funded by grants from the National Institutes of Health. While prior studies have also found a link between red-meat consumption and the development of Type 2 diabetes, the new analysis is believed to be the first time researchers have tracked changes in red-meat consumption over time with the risk of developing Type 2 diabetes. Study participants filled out detailed questionnaires about the types of food and drinks they consumed at the beginning of the study and every four years. The analysis looked at some 20 years of data. Broadly, the study showed that, compared with a group of people who had no change in red-meat intake, increasing red-meat consumption by more than a half-serving per day over a four-year period was associated with a 48 percent increase in the risk of developing Type 2 diabetes during the next four years. However, reducing red-meat consumption by the same amount during the same time period didn't cut the risk of diabetes during the next four years. It did reduce the risk by 14 percent over a longer time period, though. The changes were independent of other factors such as body weight and overall diet quality. “Our results confirm the robustness of the association between red meat and [Type 2 diabetes prevention] and add further evidence that limiting red-meat consumption over time confers benefits for…prevention,” the study authors wrote. An Pan, an assistant professor at the National University of Singapore's Saw Swee Hock School of Public Health, was the study's lead author. Other doctors say red meat in and of itself isn't necessarily the trouble. “It is not the type of protein (or meat) that is the problem; it is the type of fat,” said William J. Evans, who is affiliated with both Duke University and GlaxoSmithKline PLC., and who wrote a commentary about the study that was also published online in JAMA Internal Medicine. “It's mischaracterizing red meat as high fat,” Evans said in an interview. He said consumers could choose lean cuts of red meat such as sirloin tips or round steak over high-fat cuts like rib-eye. Dr. Pan could not be reached for comment Monday.

Money talks when it comes to weight loss

The secret to weight loss may be much simpler than anyone ever imagined – so simple, in fact, you may wonder why it hasn’t been thought of before? A study completed by Mayo Clinic researchers has discovered that money is the most effective motivator when it comes to weight loss. When conducting a comparison between study groups, one group was incentivized, the other was not. The results were overwhelming, with 62 percent of study participants from the incentivized group completing the study, compared to only 26 of the non-incentivized group. And, the incentivized group lost an average of 9.08 pounds versus 2.34 pounds in the other group. Financial incentives for weight loss began to gain popularity in January, as New Year’s resolutions to finally drop excess pounds began to dominate water cooler chatter in offices across the nation. A number of websites and wellness firms now offer individuals, as well as teams, the ability to place bets on their weight loss efforts, and some even offer additional tools to help you succeed. According to a report by the National Business Group on Health, teaming up with co-workers to whittle your middle is an effective way to lose weight.  The media lit up in the wake of New Year’s resolutions to discuss the increases in employer-incentivized weight loss competitions. Wellness consultant groups and websites, like DietBet.com and Healthywage.com, have helped tens of thousands of employees shed as much as 5 percent of their body weight in just three months – enough to make a significant  difference in certain health risk factors. The effectiveness of the program is in line with the Mayo Clinic study: money talks when it comes to weight loss. And inside the office, the team mentality only enhances success. Independent wellness firms work with employers to establish teams within the office and offer a grand prize (as much as $10,000 cash) for the winning team and smaller prizes for milestones along the way, as well as runner-up rewards. In an interview, an employee of a participating company told The Wall Street Journal that staying on track was easier because he feared letting down his team in the pursuit of $10,000. A fellow teammate responded, agreeing, “The last thing you want to do is catch the wrath of your team.” Independent firms offer complete programs, including private weigh-ins. Employees may participate on a voluntary basis and a small fee is often required, but the rewards – even if you don’t win the grand prize – often outweigh the fee. There is speculation, as with most diets, about maintaining your weight loss after the allure of the money has long passed. However, studies have shown that in team weight loss “competitions” like these, many times teammates continue to help each other stay on track. Physician-supervised weight loss is also a healthy way to not only achieve weight loss results for contests like these, but to ensure you maintain it. Your doctor can be a vital part of your weight management team and help you uncover strategies that will lead to long term weight loss success – long after you have pocketed your weight loss earnings.

Skin cancer strikes men differently

Malignant skin cancers develop in different areas of the head and neck in men and women. The reason may simply be because men are often the drivers of a car, while women are more often the passengers, according to a study in the Journal of Investigative Dermatology. Up to 20 percent of aggressive skin cancers called melanomas occur on the head and neck, which are exposed to greater amounts of ultraviolet radiation than other parts of the body. But few studies have compared gender differences in the distribution of these cancers, the researchers said. The study analyzed 279 head-and-neck melanomas diagnosed in 121 men and 158 women in their early 70s from the Champagne-Ardenne region of France, between 2004 and 2009. About half of the cancers were invasive, or had spread beyond the initial site. The data revealed two distinct patterns. In men, 57 percent of melanomas were located in the peripheral area of the head and neck, which included the scalp, forehead, temple, ears and neck, while 43 percent developed on the eyelids, nose, cheeks, chin and mouth, or the central area. In women, 79 percent of melanomas developed in the central area and 21 percent in the peripheral area. Peripheral cancers were more common on the left side in men and on the right side in women, and tended to be invasive, researchers said. Men spend more time driving than women and are often the principal driver, researchers said, which may explain the asymmetrical distribution of melanomas. The peripheral area is particularly exposed to UV radiation while traveling in a car, although longer hair on women appears to provide some protection, they said.
