(HealthDay News) – In 2008–2010, the prevalence of key health behaviors among U.S. adults varied, with about one in five adults current smokers and 62.1% overweight or obese, according to a report presented by the U.S. Centers for Disease Control and Prevention’s National Center for Health Statistics.

Charlotte A. Schoenborn, MPH, from the Division of Health Interview Statistics at the CDC in Hyattsville, MD, and colleagues used data from the 2008–2010 National Health Interview Survey to estimate the prevalence of key health behaviors. A representative sample of 76,669 adults aged ≥18 years was interviewed.

The researchers found that, in 2008–2010, 64.9% of adults were current drinkers and 20.9% were lifetime abstainers. About one in five (20.2%) were current smokers and less than half (45.8%) had attempted to quit in the last year. More than half (58.6%) of adults were never smokers. With respect to exercise, 46.1% met the federal guidelines for aerobic physical activity, 23% met guidelines for muscle-strengthening physical activity, and 19.4% met both guidelines. Most adults (62.1%) were overweight or obese, with a body mass index of 25kg/m² or more, while 36.1% were a healthy weight. Most adults (69.7%) met the Healthy People 2020 goals for adequate sleep.

“This report offers specific information about which subgroups lag in terms of adopting healthy behaviors and may serve as a reference document for the public health community in deciding how best to allocate resources to reduce disparities,” the authors write.
