Overweight and obesity affect Americans of all ages, sexes, and racial/ethnic groups. This serious health problem has been growing over the last 30 years.
According to the National Health and Nutrition Examination Survey (NHANES) 2009–2010, almost 70 percent of Americans are overweight or obese. The survey also shows differences in overweight and obesity among racial/ethnic groups.
Children also have become heavier. In the past 30 years, obesity has tripled among school-aged children and teens.
According to NHANES 2009–2010, about 1 in 6 American children ages 2–19 are obese. The survey also suggests that overweight and obesity are having a greater effect on minority groups, including Blacks and Hispanics.
Obesity happens one pound at a time. So does prevention.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for Overweight and Obesity, visit www.clinicaltrials.gov.

Benefits of quitting smoking outpace risk of modest weight gain
The improvement in cardiovascular health that results from quitting smoking far outweighs the limited risks to cardiovascular health from the modest amount of weight gained after quitting, reports a National Institutes of Health-funded community study. The study found that former smokers without diabetes had about half as much risk of developing cardiovascular disease as current smokers, and this risk level did not change when post-cessation weight gain was accounted for in the analysis.
