Abstract
BACKGROUND Subjective measures of sedentary behaviour (SB) (i.e. questionnaires and diaries/logs) are widely implemented, and can be useful for capturing type and context of SBs. However, little is known about comparative validity and reliability. The aim of this systematic review and meta-analysis was to: 1) identify subjective methods to assess overall, domain- and behaviour-specific SB, and 2) examine the validity and reliability of these methods. METHODS The databases MEDLINE, EMBASE and SPORTDiscus were searched up to March 2020. Inclusion criteria were: 1) assessment of SB, 2) evaluation of subjective measurement tools, 3) being performed in healthy adults, 4) manuscript written in English, and 5) paper was peer-reviewed. Data of validity and/or reliability measurements was extracted from included studies and a meta-analysis using random effects was performed to assess the pooled correlation coefficients of the validity. RESULTS The systematic search resulted in 2423 hits. After excluding duplicates and screening on title and abstract, 82 studies were included with 75 self-reported measurement tools. There was wide variability in the measurement properties and quality of the studies. The criterion validity varied between poor-to-excellent (correlation coefficient [R] range - 0.01- 0.90) with logs/diaries (R = 0.63 [95%CI 0.48-0.78]) showing higher criterion validity compared to questionnaires (R = 0.35 [95%CI 0.32-0.39]). Furthermore, correlation coefficients of single- and multiple-item questionnaires were comparable (1-item R = 0.34; 2-to-9-items R = 0.35; ≥10-items R = 0.37). The reliability of SB measures was moderate-to-good, with the quality of these studies being mostly fair-to-good. CONCLUSION Logs and diaries are recommended to validly and reliably assess self-reported SB. However, due to time and resources constraints, 1-item questionnaires may be preferred to subjectively assess SB in large-scale observations when showing similar validity and reliability compared to longer questionnaires.

Abstract
Objective: This review is to systematically summarize the studies examining physical activity questionnaires in children and adolescents and assess the overall validity and reliability, providing evidence on epidemiology research of physical activity in youth. Methods: A meta-analysis was performed using Stata 14.0 software. PubMed/Medline and EMBASE databases using the following terms:'Physical Activity'AND (' Questionnaire'OR'Self-report'OR'Recall') AND'Valid*'AND (' Reliab*'OR'Reproducib*'OR'Sensitiv*'OR'Responsiv*') AND (' Child*' OR'Adolescen*'OR'Youth') were searched from January 2008 to December 2018. Articles meeting the inclusion criteria were screened and adopting 'COnsensusbased Standards for the selection of health status Measurement Instruments' to evaluate the quality of the included studies. Results: This review yielded 17 articles on 20 different physical activity questionnaires, the total number of 2 778 participants for validity study and 2 137 participants for reliability study. The combined values of correlation coefficients in validity study were 0.27 (95%CI: 0.23-0.31) for moderate-to-vigorous intensity physical activity, 0.24 (95%CI: 0.18-0.30) for moderate intensity physical activity, 0.33 (95%CI: 0.24-0.42) for vigorous intensity physical activity. The combined values of intraclass correlation coefficients in reliability study were 0.75 (95%CI: 0.68-0.83) for moderate-to-vigorous intensity physical activity, 0.56 (95%CI: 0.46-0.65) for moderate intensity physical activity, 0.68 (95%CI: 0.61-0.75) for vigorous intensity physical activity. Conclusion: Until now, no questionnaires were identified for good validity and reliability to assess the physical activity level in young population.

Abstract
BACKGROUND Health-related quality of life (HRQoL) measurement in elderly people can provide appropriate information for an optimal management of physical/mental conditions. The main objective of the present study was to quantitatively assess the HRQoL among healthy elder Iranian individuals as measured by the Short-Form 36 (SF-36) questionnaire, both overall and at the level of each its single component/domain. METHODS This study was designed as a systematic review and meta-analysis, following the "Preferred Reporting Results of Systematic Reviews and Meta-Analyses" (PRISMA) guidelines. Embase, PubMed/MEDLINE, ISI/Web of Science (WOS), Scopus, and Iranian databases such as MagIran, SID and Irandoc were mined from inception up to 1st September 2017. Also the grey literature (via Google Scholar) was mined. Two reviewers independently screened titles/abstracts, assessed full-text articles, extracted data, and appraised their quality using the "Strengthening the Reporting of Observational Studies in Epidemiology" (STROBE) checklist. RESULTS Twenty five studies were included. Mean overall HRQoL was 54.92 [95%CI 51.50-58.33], lower than the value found by studies done in other countries, especially in those economically developed. The sensitivity analysis indicated stability and reliability of results. Pooled scores of each HRQoL domain/sub-scale of the SF-36 questionnaire ranged from 49.77 (physical role functioning) to 63.02 (social role functioning). CONCLUSIONS HRQoL among healthy elder Iranian individuals is generally low. Health policy-makers should put HRQoL among the elderly as a priority of their agenda, implementing ad hoc programs and providing social, economic and psychological support, as well as increasing the participation of old people in the community life and use their experiences.
