The National Health and Nutrition Examination nSurvey (NHANES) is essential in helping scien-ntists understand and address the obesity epidemic. nNHANES is the best way to track rates of overweight nand obesity in the United States since this survey pro-nvides actual measured heights and weights for a repre-nsentative sample of people. Through NHANES we can nsee there was little change in U.S. obesity rates from n1960 through 1980. However, the results of NHANES nIII, conducted from 1988–1994 first demonstrated an nalarming increase in obesity in the United States. Obe-nsity rates continued to increase through 1999. This nincrease was seen in adult men and women of all ages, nchildren and adolescents, and people of all racial and nethnic backgrounds. The continuing increase in obesity nled some to predict that we would all likely be obese at nsome point in the future.
