Why Do Statistics About Overweight And Obesity Differ?
Prior studies in the United States have used the 1959 or the 1983 Metropolitan Life Insurance tables of desirable weight-for-height as the reference for overweight.[3] More recently, a number of Government agencies and scientific health organizations have estimated overweight using data from a series of cross-sectional surveys called the National Health Examination Surveys (NHES) and the National Health and Nutrition Examination Surveys (NHANES). The National Center for Health Statistics (NCHS) of the Centers for Disease Control and Prevention (CDC) conducted these surveys. Each had three cycles: NHES I, II, and III spanned the period from 1960 to 1970, and NHANES I, II, and III were conducted in the 1970's, 1980's, and early 1990's. Since 1999, NHANES has become a continuous survey......... Posted by: JoAnn Permalink Higher Death Rates With Obesity
To better quantify the health risks associated with obesity, the Pitt researchers, collaborating with scientists from six other institutions, examined the rates of death and of newly diagnosed coronary heart disease over a seven year period of 90,185 women in five specific weight categories. The women, all participants of the Women's Health Initiative-Observational Study, were assigned to the weight categories based on the weight-to-height ratio known as body mass index (BMI): normal (BMI 18.5 24.9), overweight (BMI 25.0 29.9), obesity 1 (BMI 30.0 34.9), obesity 2 (BMI 35.0 ¨C 39.9) and extreme obesity (BMI 40). The study showed that white women in the obesity 1 category (approximately 60 pounds above a normal weight for a 5-foot, 5-inch tall woman) to have a 12 percent higher risk of death over the seven year follow-up period, but extremely obese women (approximately 110 pounds above a normal weight for a 5-foot, 5-inch tall woman) had an alarming 86 percent higher risk of death than their normal weight counterparts.........

"Volunteering in a grade school may not seem immediately appealing to older Americans," said Erwin Tan, Ph.D., assistant professor of geriatrics at Johns Hopkins University and lead author of the study. "But honestly, our volunteers say it's an enriching experience, and, it turns out, it may be good for you". In a study of 113 men and women 60 and older, Hopkins scientists investigated the subjects' physical health as it correlation to their activity levels. Fifty-nine were involved in the Experience Corps Baltimore, a volunteer program designed at Johns Hopkins' Center for Aging, which places elderly volunteers in kindergarten and grammar school classrooms to be mentors and tutors for 15 hours a week. The other 54 individuals were not enrolled in any activity-based volunteer work and served as a comparison group. The Hopkins scientists concluded that elderly adults who failed suggested U.S. standards for physical activity when they started volunteering in public grammar schools doubled the amount of calories they burned after volunteering for just one school year. The Centers for Disease Control recommends that all Americans be physically active or exercise for half an hour a day, five days a week......... Posted by: Janet Permalink Source Tips To Reduce Your Cancer Risk While Grilling
But Dana-Farber Cancer Institute nutritionist Stephanie Vangsness, RD, LDN, CNSD, says that doesn't mean you have to give up those summertime favorites like burgers, steaks, and ribs. "It's really about being careful and making wise choices." There are two risk factors to keep in mind. The high heat of grilling reacts with proteins in red meat, poultry, and fish to create heterocyclic amines (HCAs). Studies have linked these chemicals to cancer. Another form of cancer-causing agents, called polycyclic aromatic hydrocarbons (PAHs), are found in the smoke. They form when fat and juices from meat products drip on to the heat source. As the smoke rises, it can stick to the surface of the meat. What can you do to lower your risk? Here are some tips to make sure your summer grilling is safe. Prep the meat. Choose lean cuts of meat instead of high-fat varieties, such as ribs and sausage. Trim all excess fat and remove the skin.........

The researchers, led by Constance Bacon, a former post-doctoral fellow at HSPH, and Eric Rimm , associate professor of epidemiology and nutrition at HSPH, surveyed 22,086 healthy subjects between the ages of 40 and 75 from the Health Professionals Follow-up Study who reported good or very good erectile function and no major chronic disease before 1986. Among the participants, 17.7 percent (3,905) reported new onset of ED between 1986 and 2000. The scientists adjusted the results to take into account those with and without prostate cancer during the follow-up period, since prostate cancer therapys, such as radiation or surgery, may lead to ED. The results showed that both smoking and obesity were associated with a higher risk of the development of ED among previously healthy men with good erectile function. The scientists also found that regular physical activity showed a strong inverse association with ED risk. "We found a 2.5-fold difference in risk of ED when we compared obese men who did little exercise with men who were not overweight and averaged 30 minutes of vigorous exercise a day. (Obesity was defined as a body mass index of more than 30 kilograms in weight divided by the square of height in meters.) For men younger than 55 there was a 4-fold difference in risk for the same comparison," said Rimm. Alcohol consumption did not increase the risk of ED. In general, men without prostate cancer showed stronger associations with these lifestyle factors than those with prostate cancer......... Posted by: Janet Permalink Source Pork Rivals Chicken In Terms Of Leanness
The new research, presented at the Institute of Food Technologists annual meeting, revealed a surprising fact: pork tenderloin is just as lean as the leanest type of chicken - a skinless chicken breast. The U.S. Department of Agriculture (USDA) analysis found that pork tenderloin contains only 2.98 grams of fat per 3-ounce serving1, compared to 3.03 grams of fat in a 3-ounce serving of skinless chicken breast.2 Pork tenderloin meets government guidelines for "extra lean" status. "These new data illustrate how pork is changing to meet consumers' concerns about fat content," said Ceci Snyder, MS, RD, Assistant Vice President of Consumer Marketing for the National Pork Board. "Some of the more common cuts of pork you can find in today's meat case are now lower in fat and saturated fat because America's pork producers have improved feeding and breeding practices to deliver the leaner products that consumers demand." In other words, pigs have gone on a diet. On average, six common cuts of pork are 16 percent leaner than 15 years ago, and saturated fat has dropped 27 percent......... Posted by: JoAnn Permalink Source Five Steps To Help Curb Child Obesity
In Child Obesity: A Parent's Guide to a Fit, Trim, and Happy Child, nationally recognized expert on child obesity Dr. Goutham Rao uses the latest and best medical evidence available to show you how to help your child avoid or overcome this prevalent and dangerous health problem. In the first part of his easy-to-read and informative book, Dr. Rao gives you the knowledge you need to understand the scope of the problem. He identifies the five principal culprits for obesity among children: soft drinks ("liquid candy"); fast food; television and video games; the inactivity of youngsters both at school and at play; and the changing patterns of family behavior, which have led to irregular meal times and the over-consumption of "convenience" foods. In the second half of the book, Dr. Rao carefully explains a rational approach to helping your child achieve or maintain a healthy weight, including the science of changing people's behavior. You will also find several typical stories of overweight children, ranging from a heavy thirteen-month infant boy to a sixteen-year-old obese and self-conscious girl. With the help of their parents these children managed to achieve a healthy weight by following simple, practical advice without resorting to gimmicks or "miracle cures."........

Richmond and his colleagues carefully analyzed data from the National Longitudinal Study of Adolescent Health, a school-based study of 7th-to-12th graders. "Obesity is a growing problem in all adolescents, but it affects racial and ethnic minorities disproportionately," Richmond says. "Since physical activity is one protective factor against obesity that we can influence, we wanted to know whether schools might help determine physical activity levels." Their key findings are as follows:
Posted by: JoAnn Permalink Source Is It Safe To Swim After Eating?
"If you've had a light meal with no alcohol, there's no point in waiting that long. But if you've eaten steak or poutine, you should really wait a few hours." The reason is simple, as per Ledoux. "Foods that are rich in fat are harder to digest than carbohydrates. It takes more oxygen to metabolize them, so they aren't as good a source of energy for physical activity". Ledoux is a sports medicine specialist with a rare combination of expertise in both nutrition and physical education. She notes that muscle cramping is not caused by swimming in particular, but by any physical exertion. "However, if you have cramps in the water, it can be a catastrophe". Parents may keep their children out of the water after a meal because of a false belief that there's a link between digestion and fainting while swimming. Ledoux explains that the real cause of fainting in the water is the heart's reaction to the shock of the cold water on very hot skin. It is true that body temperature rises during digestion, increasing the risk of shock, but this can happen even several hours after eating. A lengthy sunbath can have the same result.........

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.".
