Pedometer-measured physical activity and health behaviors in U.S. adults

The study provides descriptive, epidemiological data on the average number of steps per day taken by U.S. adults and identifies predictors of pedometer-measured physical activity based on demographic and self-reported behavioral characteristics. Results show U.S. adults take fewer steps than those in Switzerland, Australia and Japan, suggesting that low levels of ambulatory physical activity contribute to the high prevalence of adult obesity in the U.S.
