Within the organisational design domain, BMM culture, leadership, and lived experiences were prominent. In the social network domain, social media, storytelling, and mutual accountability maintained high connectivity. Engagement with other BBM activities reinforced the community support domain. Within the health domain, positive reinforcement from improved mental health was more prominent than from weight loss.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>This systems analysis of participant motivations to continued engagement with exercise classes shows how M\u0101ori and Pacific cultural values and ways of engaging have been incorporated into BBM to build ongoing participation and, thus, potential positive health outcomes. The multiple feedback loops provide further opportunities to refine the programme. The study also demonstrates the value of systems thinking for complex health challenges such as sustained weight loss. With reliable resourcing, BBM is well placed to make a difference to the obesity-related health inequities that disproportionately affect M\u0101ori and Pacific people.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1071\/hc26034","type":"journal-article","created":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T01:02:07Z","timestamp":1785978127000},"source":"Crossref","is-referenced-by-count":0,"title":["Motivation for engagement in a M\u0101ori- and Pacific-driven exercise programme in New Zealand: a community-based system dynamics approach"],"prefix":"10.1071","author":[{"given":"Emery","family":"Grant","sequence":"first","affiliation":[{"name":"Medical Student, Faculty of Medical and Health Science, University of Auckland A , , .","place":["Auckland, New Zealand"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boyd","family":"Swinburn","sequence":"additional","affiliation":[{"name":"Professor of Population Nutrition and Global Health B , , , .","place":["Auckland, New Zealand"]},{"name":"University of Auckland B , , , .","place":["Auckland, New Zealand"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fa\u2019asisila","family":"Savila","sequence":"additional","affiliation":[{"name":"Senior Research Fellow C , , , .","place":["Auckland, New Zealand"]},{"name":"Pacific Health, University of Auckland C , , , .","place":["Auckland, New Zealand"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Truely","family":"Harding","sequence":"additional","affiliation":[{"name":"Research Fellow, School of Medicine, Faculty of Medical & Health Sciences D , , , .","place":["Auckland, New Zealand"]},{"name":"University of Auckland D , , , .","place":["Auckland, New Zealand"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1401-8191","authenticated-orcid":true,"given":"Warwick","family":"Bagg","sequence":"additional","affiliation":[{"name":"Professor of Medicine, School of Medicine, University of Auckland E , , .","place":["Auckland, New Zealand"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6657-9401","authenticated-orcid":true,"given":"Felicity","family":"Goodyear-Smith","sequence":"additional","affiliation":[{"name":"Felicity Goodyear-Smith, Professor of General Practice & Primary Health Care, Department of General Practice & Primary Health Care F , , , .","place":["Auckland, New Zealand"]},{"name":"University of Auckland F , , , .","place":["Auckland, New Zealand"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"67","published-online":{"date-parts":[[2026,8,6]]},"reference":[{"issue":"10481","key":"2026080521020327400_R1","doi-asserted-by":"publisher","first-page":"813","DOI":"10.1016\/S0140-6736(25)00355-1","article-title":"Global, regional, and national prevalence of adult overweight and obesity, 1990\u20132021, with forecasts to 2050: a forecasting study for the Global Burden of Disease Study 2021.","volume":"405","author":"Ng","year":"2025","journal-title":"The Lancet"},{"issue":"10431","key":"2026080521020327400_R2","doi-asserted-by":"publisher","first-page":"1027","DOI":"10.1016\/S0140-6736(23)02750-2","article-title":"Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults.","volume":"403","author":"Phelps","year":"2024","journal-title":"The Lancet"},{"key":"2026080521020327400_R3","unstructured":"Ministry of Health.
