Objective physical activity measurement in the osteoarthritis initiative: Are guidelines being met?
Open accessAbstract
Objective: Osteoarthritis (OA) clinical practice guidelines identify a substantial therapeutic role for physical activity, but objective information about the physical activity of this population is lacking. The aim of this study was to objectively measure levels of physical activity in adults with knee OA and report the prevalence of meeting public health physical activity guidelines. Methods: Cross‐sectional accelerometry data from 1,111 adults with radiographic knee OA (49–84 years old) participating in the Osteoarthritis Initiative accelerometry monitoring ancillary study were assessed for meeting the aerobic component of the 2008 Physical Activity Guidelines for Americans (≥150 minutes/week moderate‐to‐vigorous–intensity activity lasting ≥10 minutes). Quantile regression was used to test median sex differences in physical activity levels. Results: Aerobic physical activity guidelines were met by 12.9% of men and 7.7% of women with knee OA. A substantial proportion of men and women (40.1% and 56.5%, respectively) were inactive, having done no moderate‐to‐vigorous activity that lasted 10 minutes or more during the 7 days. Although men engaged in significantly more moderate‐to‐vigorous activity (average daily minutes 20.7 versus 12.3), they also spent more time in no or very‐low‐intensity activity than women (average daily minutes 608.2 versus 585.8). Conclusion: Despite substantial health benefits from physical activity, adults with knee OA were particularly inactive based on objective accelerometry monitoring. The proportions of men and women who met public health physical activity guidelines were substantially less than those previously reported based on self‐reported activity in arthritis populations. These findings support intensified public health efforts to increase physical activity levels among people with knee OA.

Over 90% of people with knee osteoarthritis did not meet the physical activity guidelines of 150 minutes of moderate to vigorous physical activity per week.
“A 2011 study using accelerometers found that over 90% of people with knee OA did not meet the physical activity guidelines of 150 minutes of moderate to vigorous physical activity (MVPA) per week [8].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
