This systematic review aimed to evaluate the effects of combined behaviour change and exercise interventions on objectively measured total PA (primary outcome) and other device\u2010measured activity behaviours, including moderate\u2010to\u2010vigorous physical activity (MVPA), steps and sedentary behaviour, in people with hip or knee OA (secondary outcomes). Five databases were searched from inception until September 2025. The titles of identified randomised controlled trials (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u2009907) were screened by two reviewers, and 12 studies involving 1162 participants with OA were included. Study quality was assessed using the SIGN checklist, and certainty of evidence was evaluated using the GRADE approach. Most studies were rated as low quality, and the certainty of evidence was low to very low across all outcomes. Random\u2010effects meta\u2010analyses found little to no difference for the use of behaviour change and exercise interventions for our primary outcome of total PA postintervention (3 studies,\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u2009246; MD 21.25\u2009min\/day, 95% CI \u201026.11\u201368.61) or at 12\u2010month follow\u2010up (3 studies,\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u2009221; MD 30.52\u2009min\/day, 95% CI \u201025.42\u201386.45). A meta\u2010analysis of four studies (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u2009307) found a small increase in device\u2010measured MVPA at short\u2010term follow\u2010up (MD 2.53\u2009min\/day, 95% CI 0.18 to 4.88;\n                    <jats:italic>I<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u2009=\u200921%). No significant effects were observed for any of the other outcomes (long\u2010term MVPA, steps or sedentary behaviour). The existing evidence is limited, and findings should be interpreted cautiously given the low to very low certainty of the evidence and the small number of studies available. This highlights the need for higher quality studies with clear BCT reporting and fidelity procedures to establish whether behaviour change combined with exercise improves PA behaviours.\n                  <\/jats:p>","DOI":"10.1155\/jare\/5852133","type":"journal-article","created":{"date-parts":[[2026,8,17]],"date-time":"2026-08-17T09:52:07Z","timestamp":1786960327000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Behaviour Change Interventions Combined With Exercise on Device\u2010Measured Physical Activity in People With Hip and Knee Osteoarthritis: A Systematic Review and Meta\u2010Analysis"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8472-4940","authenticated-orcid":false,"given":"Rebecca M.","family":"Meiring","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitchell","family":"Campbell","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abhishta","family":"Sood","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2513-6011","authenticated-orcid":false,"given":"Daniel","family":"O\u2019Brien","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0098-1203","authenticated-orcid":false,"given":"Estelle D.","family":"Watson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,17]]},"reference":[{"key":"e_1_2_11_1_2","doi-asserted-by":"crossref","first-page":"184","DOI":"10.1016\/j.joca.2021.04.020","article-title":"Epidemiology of Osteoarthritis","volume":"30","author":"Allen K.","year":"2022","journal-title":"Osteoarthritis and Cartilage"},{"key":"e_1_2_11_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.joca.2013.08.003"},{"key":"e_1_2_11_3_2","doi-asserted-by":"publisher","DOI":"10.1123\/jpah.10.6.777"},{"key":"e_1_2_11_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/art.27760"},{"key":"e_1_2_11_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/acr.22432"},{"key":"e_1_2_11_6_2","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.161.19.2309"},{"key":"e_1_2_11_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.joca.2018.07.002"},{"key":"e_1_2_11_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbspin.2021.105207"},{"key":"e_1_2_11_9_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2017-017042"},{"key":"e_1_2_11_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cct.2014.08.010"},{"key":"e_1_2_11_11_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-020-04720-9"},{"key":"e_1_2_11_12_2","doi-asserted-by":"publisher","DOI":"10.2105\/ajph.2014.302270"},{"key":"e_1_2_11_13_2","doi-asserted-by":"publisher","DOI":"10.1177\/0269215518769986"},{"key":"e_1_2_11_14_2","doi-asserted-by":"publisher","DOI":"10.3310\/hta19990"},{"key":"e_1_2_11_15_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12889-018-6064-7"},{"key":"e_1_2_11_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbmt.2020.11.002"},{"key":"e_1_2_11_17_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12889-018-6062-9"},{"key":"e_1_2_11_18_2","doi-asserted-by":"publisher","DOI":"10.1177\/0269215514536210"},{"key":"e_1_2_11_19_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0219482"},{"key":"e_1_2_11_20_2","doi-asserted-by":"publisher","DOI":"10.1136\/ard-2023-225041"},{"key":"e_1_2_11_21_2","doi-asserted-by":"publisher","DOI":"10.1136\/annrheumdis-2018-213585"},{"key":"e_1_2_11_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.heliyon.2022.e08991"},{"key":"e_1_2_11_23_2","doi-asserted-by":"publisher","DOI":"10.3899\/jrheum.140054"},{"key":"e_1_2_11_24_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ypmed.2008.12.001"},{"key":"e_1_2_11_25_2","doi-asserted-by":"publisher","DOI":"10.1177\/1941738115616917"},{"key":"e_1_2_11_26_2","doi-asserted-by":"publisher","DOI":"10.3928\/19404921-20190319-02"},{"key":"e_1_2_11_27_2","article-title":"The PRISMA 2020 Statement: an Updated Guideline for Reporting Systematic Reviews","volume":"372","author":"Page M.
