Lack of sleep could be more dangerous for women than men

Women who get less than the recommended eight hours sleep a night are at higher risk of heart disease and heart-related problems than men with the same sleeping patterns.

Research by the University of Warwick and University College London has found that levels of inflammatory markers vary significantly with sleep duration in women, but not men.

The study, published today (Weds) in the American journal Sleep, found levels of Interleukin-6 (IL-6), a marker related to coronary heart disease, were significantly lower in women who reported sleeping eight hours as compared with 7hours.

A second marker, High-sensitivity C-reactive protein (hs-CRP), is predictive of future cardiovascular morbidity. Levels of hs-CRP were significantly higher in women who reported sleeping five hours or less.

Lead author of the study, Associate Professor of Biochemical Medicine at Warwick Medical School Michelle Miller said short-term sleep deprivation studies have shown that inflammatory markers are elevated in sleep-deprived individuals, suggesting that inflammatory mechanisms may play a role in the cardiovascular risk associated with sleep deprivation.

She said: "Our study may provide some insight into a potential mechanism for the observation in previous studies which indicates an increased risk of death from cardiovascular disease in individuals who have less than five hours sleep per night and increased risk of non-cardiovascular death in long sleepers."

This is the first large-scale study to describe the associations between measures of inflammation and sleep duration in both men and women.

ADA releases updated position paper on vegetarian diets

ADA releases updated position paper on vegetarian diets
July 1st, 2009

The American Dietetic Association has released an updated position paper on vegetarian diets that concludes such diets, if well-planned, are healthful and nutritious for adults, infants, children and adolescents and can help prevent and treat chronic diseases including heart disease, cancer, obesity and diabetes.

ADA's position, published in the July issue of the Journal of the American Dietetic Association, represents the Association's official stance on vegetarian diets:

"It is the position of the American Dietetic Association that appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate and may provide health benefits in the prevention and treatment of certain diseases. Well-planned vegetarian diets are appropriate for individuals during all stages of the life-cycle including pregnancy, lactation, infancy, childhood and adolescence and for athletes."

ADA's position and accompanying paper were written by Winston Craig, PhD, MPH, RD, professor and chair of the department of nutrition and wellness at Andrews University; and Reed Mangels, PhD, RD, nutrition advisor at the Vegetarian Resource Group, Baltimore, Md.

The revised position paper incorporates new topics and additional information on key nutrients for vegetarians, vegetarian diets in the life cycle and the use of vegetarian diets in prevention and treatment of chronic diseases. "Vegetarian diets are appropriate for all stages of the life cycle," according to ADA's position. "There are many reasons for the rising interest in vegetarian diets. The number of vegetarians in the United States is expected to increase over the next decade."

Mississippi's still fattest but Alabama closing in

Mississippi's still king of cellulite, but an ominous tide is rolling toward the Medicare doctors in neighboring Alabama: obese baby boomers.

It's time for the nation's annual obesity rankings and, outside of fairly lean Colorado, there's little good news. Obesity rates among adults rose in 23 states over the past year and didn't decline anywhere, says a new report from the Trust for America's Health and the Robert Wood Johnson Foundation.

And while the nation has long been bracing for a surge in Medicare as the boomers start turning 65, the new report makes clear that fat, not just age, will fuel much of those bills. In every state, the rate of obesity is higher among 55- to 64-year-olds - the oldest boomers - than among today's 65-and-beyond.

That translates into a coming jump of obese Medicare patients that ranges from 5.2 percent in New York to a high of 16.3 percent in Alabama, the report concluded. In Alabama, nearly 39 percent of the oldest boomers are obese.

Health economists once made the harsh financial calculation that the obese would save money by dying sooner, notes Jeff Levi, executive director of the Trust, a nonprofit public health group. But more recent research instead suggests they live nearly as long but are much sicker for longer, requiring such costly interventions as knee replacements and diabetes care and dialysis. Studies show Medicare spends anywhere from $1,400 to $6,000 more annually on health care for an obese senior than for the non-obese.

Pessimism Drives Risky Behavior In Teens

Researchers have discovered that one in seven adolescents believe that it is highly likely that they will die before age 35, and this belief predicted that the adolescents would engage in risky behaviors.

Lead investigator Iris Borowsky, M.D., Ph.D. of the University of Minnesota Medical School and colleagues analyzed data collected by the National Longitudinal Study of Adolescent Health, a nationally representative sample of more than 20,000 youth in grades 7 through 12 during three separate study years.

In the first set of interviews, nearly 15 percent of adolescents predicted they had a 50/50 chance or less of living to age 35. Those who engaged in risky behaviors such as illicit drug use, suicide attempts, fighting, or unsafe sexual activity in the first year were more likely in subsequent years to believe they would die at a young age.

Those who predicted that they’d die young during the first interview were more likely in later years to begin engaging in these same risky behaviors and have poor health outcomes. Notably, these teens were significantly more likely to be diagnosed with HIV/AIDS just six years later, regardless of their sexual preference.
