Provo, UT – Obese women may be more likely to reduce their physical activity level over time compared to non-obese women, according to a new study from Brigham Young University.

For the study, 254 women – 124 of whom were obese – wore an accelerometer to measure their activity level for one week at the beginning of the study and then for another week 20 months later, the study abstract states.

On average, obese women saw their physical activity level drop 8 percent, while non-obese women maintained their activity level throughout the study. The activity drop was the equivalent to spending 28 minutes less per week engaged in moderate to vigorous physical activity, according to the abstract.

The study was published online March 20 in the journal Obesity.
