Abstract

Background: Physical activity benefits have been extensively studied. However, the public health guidelines seem unclear about the relationships between steps and movements with healthy biomarkers for people with (PWD) and without disabilities (PWOD), respectively. While public health guidelines illustrate types of exercise (eg, running, swimming), it is equally important to provide data-driven recommended amounts of daily steps or movements to achieve health biomarkers and further promote a physically active lifestyle. Methods: Data from the National Health and Nutrition Examination Survey 2003–2006 were used. The authors conducted sensitivity, specificity, and receiver-operating-characteristic curve analyses regarding cut points from ActiGraph 7164 of daily steps and movements for health biomarkers (eg, body mass index, cholesterol) in PWD (2178 participants) and PWOD (4414 participants). The authors also examined the dose relationships of steps, movements, and healthy biomarkers in each group. Results: The authors found significant differences in the cut points of daily steps and movement for health biomarkers in PWD and PWOD. For daily steps, cut points of PWD were ranged from 3222 to 8311 (area under the receiver-operating-characteristic curve [AUC] range = 0.52–0.93) significantly lower than PWOD’s daily steps (range = 5455–14,272; AUC = 0.58–0.87). For daily movement, cut points of PWD were ranged from 115,451 to 430,324 (AUC = 0.53–0.91) significantly lower than the PWOD’s daily movements (range = 215,288–282,307; AUC = 0.60–0.88). The authors found strong but different dose relationships of many biomarkers in each group. Conclusions: PWD need fewer daily steps or movement counts to achieve health biomarkers than PWOD. The authors provided data-driven, condition-specific recommendations on promoting a physically active lifestyle.
