American Society for Nutrition

December 2006 American Journal of Clinical Nutrition includes the following editorial and several articles about obesity, cognition, metabolic syndrome, cardiovascular disease and older adults.

Editorial: Baak MA, Visscher TLS. Public health succes in recent decades may be in danger if lifestyles of the elderly are neglected. Am J Clin Nutr 2006 84: 1257-1258.

Summary
Obesity comes with an unfavorable cardiovascular disease risk profile and obesity is clearly associated with a decrease in life expectancy and with an increase in unhealthy life-years. Additionally obesity predicts disability in adults aged 65-100 years old. Losing weight is a special topic in the older generation. There are two commonly sited reasons why weight loss could be not beneficial in the obese elderly population: the obesity associated risk of mortality decreases with aging, and the body mass index (BMI) range which is associated with the lowest mortality risk increases with aging. But the insight regarding these rationales have changed: the absolute risk of mortality associated with obesity increases. Which results in a bigger gap between an obese and a normal-weight person in the older population. And as shown in the study by Villareal et al. there is an improvement in cardiovascular disease risk factors without negative effects on frailty indexes if older obese persons are participating in a diet and exercise program.
