...study by Australian researchers finds that being overweight may be a boon for the elderly: among the 9,240 adults ages 70 to 75 in the study, those who were overweight were the least likely to die over 10 years, compared with people who were of normal weight or obese...
...study, published Thursday in the Journal of the American Geriatrics Society, looked at data from two long-term population-based studies and found that adults who were overweight had an average 13% lower risk of death from any cause over 10 years, compared with those who were of normal weight. Those who were underweight were 76% more likely to die, while the obese had the same mortality risk as those of normal weight. Researchers also found that being sedentary increased the risk of death in men by 28%; in women, the risk was doubled. (See how exercise can help aging...
...report adds to the ongoing scientific debate over how to define ideal weight in adults and whether the widely used measure of weight categories - body mass index (BMI), a measure of body fat based on a ratio of weight and height - is equally useful for all age groups. The World Health Organization defines normal weight as a BMI of 18.5 to 24.9 kg/m2; overweight is defined as a BMI of 25 to 29.9 kg/m2. A BMI of 30 or higher is considered obese, and under 18.5 underweight...
...study by U.S. researchers at the Centers for Disease Control and Prevention and the National Cancer Institute found that overweight adults had a slightly lower risk of death than their normal-weight peers, largely because they were less likely to die from a variety of diseases, including Alzheimer's, infections and lung disease. Another study in 2005, published in Obesity, analyzed data on more than 11,000 Canadian adults for over 12 years and found that people who were overweight were 17% less likely to die than those of normal weight. Underweight adults, by contrast, had a 73% higher risk...
...current study looked only at major causes of mortality, which the researchers grouped together as cardiovascular disease, cancer, chronic respiratory disease or other. In all weight categories, the leading causes of death were cardiovascular disease and cancer. The lowest risk of death from either cause occurred in overweight adults.
