“…We used terms such as “sedentary behaviors questionnaire”, “sitting”, “sedentary behaviors assessment”, “sedentary time questionnaire”, and “subjective assessment of sedentary activity”. After excluding duplicates and screening the titles and abstracts, the search resulted in 22 relevant SB questionnaires (detailed description is shown in Table S1 ) that assessed sitting time via a multiple-item questionnaire [ 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 ]. Some studies were validated with objective measurements, but five were found to be more specific for assessing sedentary behaviors and were therefore selected and fully reviewed.…”
