Subsequently, an empirical application was conducted from March to July 2025, involving 940 participants across six regions in Hunan Province. The Fuzzy Comprehensive Evaluation (FCE) method was utilized to analyze the data.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The social support evaluation system for adolescent physical health promotion consists of 4 primary indicators (government support, school support, family support, and community support), 19 secondary indicators, and 54 tertiary indicators. Among the primary indicator weights, government support had the largest weight (0.3764), followed by school support (0.2885), family support (0.2442), and community support (0.0909). For social support of adolescent physical health promotion in Hunan Province, government support scored the highest (87.56), reaching a \u201cgood\u201d level; school support (80.82) and family support (75.40) were also rated as \u201cgood\u201d; and community support had the lowest score (60.35).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study underscores the significant role of social support in adolescent physical health promotion. Relatively stable social support for adolescent physical health promotion mainly includes four dimensions: government, school, family, and community. Overall, the level of social support for adolescent physical health promotion in Hunan Province is relatively positive, but structural imbalances and other shortcomings still exist. Future efforts should focus on four key stakeholders, government responsibility: bridging the gap between policy intent and implementation, school implementation: overcoming academic pressure and resource constraints, family participation: reshaping parental perceptions and health literacy, and community extension: revitalizing grassroots support systems, so as to promote the comprehensive physical and mental development of adolescents.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpubh.2026.1808568","type":"journal-article","created":{"date-parts":[[2026,7,15]],"date-time":"2026-07-15T06:11:10Z","timestamp":1784095870000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Social support ecosystems for adolescent physical activity: a mixed-methods evaluation framework and empirical evidence from China"],"prefix":"10.3389","volume":"14","author":[{"given":"Heng","family":"Luo","sequence":"first","affiliation":[{"name":"School of Physical Education, Xiangnan University","place":["Chenzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zelong","family":"Chen","sequence":"additional","affiliation":[{"name":"Xiangsihu College of Guangxi Minzu University, Guangxi University for Nationalities","place":["Nanning, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,7,15]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"e6407","DOI":"10.1097\/MD.0000000000006407","article-title":"Association between physical activity, sedentary behavior, and fitness with health related quality of life in healthy children and adolescents: a protocol for a systematic review and meta-analysis","volume":"96","author":"Bermejo-Cantarero","year":"2017","journal-title":"Medicine"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"563","DOI":"10.1007\/s40894-023-00227-7","article-title":"The hodgepodge reality: a qualitative systematic review of the challenges and barriers in child and adolescent mental health care systems","volume":"9","author":"Carbonell","year":"2024","journal-title":"Adolesc Res Rev"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"247","DOI":"10.1016\/s0140-6736(12)60646-1","article-title":"Global physical activity levels: surveillance progress, pitfalls, and prospects","volume":"380","author":"Hallal","year":"2012","journal-title":"Lancet"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1139\/apnm-2021-0447","article-title":"Prevalence and correlates of meeting physical activity, screen time and sleep duration guidelines among Brazilian adolescents: findings from ERICA","volume":"47","author":"Wohlgemuth","year":"2022","journal-title":"Appl Physiol Nutr Metab"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"20327","DOI":"10.3402\/gha.v6i0.20327","article-title":"Correlates of physical activity in adolescence: a study from a developing country","volume":"6","author":"Behjat","year":"2013","journal-title":"Glob Health Action"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"85","DOI":"10.1093\/eurpub\/ckp100","article-title":"The prevalence of sedentary behaviours and physical activity in Hungarian youth","volume":"20","author":"Pal","year":"2010","journal-title":"Eur J Pub Health"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"548","DOI":"10.2298\/VSP1306548D","article-title":"Nutritional and physical activity behaviours and habits in adolescent population of Belgrade","volume":"70","author":"\u0110or\u0111evi\u0107-Niki\u0107","year":"2013","journal-title":"Vojnosanit Pregl"},{"key":"ref8","doi-asserted-by":"publisher","first-page":"14382","DOI":"10.3390\/ijerph192114382","article-title":"Physical activity and social support to promote a health-promoting lifestyle in older adults: an intervention study","volume":"19","author":"Huang","year":"2022","journal-title":"Int J Environ Res Public Health"},{"key":"ref9","first-page":"19","volume-title":"Support System and Mutual Help: Multi Disciplinary Explorations","author":"Caplan","year":"1974"},{"key":"ref10","doi-asserted-by":"publisher","first-page":"53","DOI":"10.2307\/2626957","article-title":"Stress, coping, and social support processes: where are we?
