WHO’s recommendations on physical activity (> 150 min of MPA or > 75 min of VPA or an equivalent combination). Cohens Kappa (к) with 95% Confidence Interval (CI) for comparison between self-reported measures and the objectively measure. Specificity and sensitivity for self-reported measures compared to the objective measure. n = 89
aCalculated as a combination of minutes MVPA and VPA (described in Additional file 1)
bCombining both answers on MVPA and VPA-questions (described in Additional file 1)
cOpen-ended questions categorized into closed-ended categories
dSpecificity is the number of participants with PA-levels below the recommendations both measured by self-report and objectively as a percentage of those with PA-levels below according to the objective measure
eSensitivity is the number of participants with PA-levels above the recommendations both measured by self-report and objectively as a percentage of those with PA-levels above according to the objective measure
