...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 was actually two studies, both conducted by the Centers for Disease Control and Prevention (CDC). The first one, which focused on adults, surveyed 5,555 men and women age 20 and older, using their height and weight measurements to calculate what's known as body mass index (BMI). In general, people with a BMI of 25 to 29.9 are considered overweight, and those with a 30 or higher are obese...
Previous surveys had tracked a steady growth in national BMI from 1976 to 1980, 1988 to 1994, and again from 1999 to 2000. But this study - which spans the period from 2000 to 2008 - showed no significant change. The burden of the weight gain that was documented in those other studies is not being borne evenly. Over 72% of men are overweight, compared with just over 64% of women. Yet women are worse off in the obesity category - 35.5%, compared with 32.2% for men. Ethnicity makes a difference too - sometimes a big one. The least obese women are non-Hispanic...
Since HealthyWage.com launched in October, Sisson and some 5,000 other hopefuls have signed up for the site, which gets corporate sponsors to give a cash reward to obese users who during a specified time period move from an unhealthy to a healthy body mass index (BMI). (This typically translates into a weight loss of between 30 and 80 lb.) Members can either sign up for free - according to a company rep, the final deadline to enter the next 12-month challenge is Jan. 20 - and win $100 or "super-size" their weight-loss incentives by putting as much...
HealthyWage, which makes money through advertising and sponsorships, claims it can save the health care system $1,150 in obesity-related costs for each person who slims down to a healthy BMI. But the challenge is hardly an easy payout. Sisson, who tips the scales at just over 200 lb., will have to lose 50 lb. in a year and check in with the site about her food intake and physical activity every week. She also has to get her physician to call HealthyWage to verify her weight at the beginning and end of the challenge...
