Abstract

To determine how many steps·day -1 equate to current moderate-to-vigorous physical activity (MVPA) guidelines in a population from the Lower Mississippi Delta (LMD) of the United States, 58 overweight adults wore an Actigraph accelerometer (GT3X) for up to 2 weeks. Min·day -1 in MVPA was a good predictor of steps·day -1 (r 2 = 0.62; p < 0.001; linear regression), such that 30 min of daily MVPA equated to 9154 steps·day -1 (mixed-model approach). Using receiver operating characteristic analysis, sensitivity and specificity were optimized at 8357 steps·day -1. Results indicate that overweight residents of the LMD should be accumulating at least 8300-9100 steps·day -1 to meet the recommendation of 30 min·day -1 MVPA.
