This three\u2010wave study examined developmental trajectories and within\u2010person bidirectional associations between PA and WSS in 325 Chinese adolescents (\n                    <jats:italic>M<\/jats:italic>\n                    <jats:sub>\n                      <jats:italic>age<\/jats:italic>\n                    <\/jats:sub>\n                    \u2009=\u200915.41), using latent growth curve and random\u2010intercept cross\u2010lagged panel models to disentangle stable between\u2010person differences from temporal fluctuations. PA showed a significant linear decrease (\n                    <jats:italic>\u03b2<\/jats:italic>\n                    \u2009=\u2009\u2212.25) while WSS linearly increased (\n                    <jats:italic>\u03b2<\/jats:italic>\n                    \u2009=\u2009.31). Parallel growth analyses revealed that higher initial PA predicted slower WSS accumulation (\n                    <jats:italic>\u03b2<\/jats:italic>\n                    \u2009=\u2009\u2212.22), and higher initial WSS forecasted steeper PA declines (\n                    <jats:italic>\u03b2<\/jats:italic>\n                    \u2009=\u2009\u2212.20). Critically, reciprocal within\u2010person effects emerged only during the academic semester (T1\u2009\u2192\u2009T2): deviations above one's typical PA level reduced subsequent WSS (\n                    <jats:italic>\u03b2<\/jats:italic>\n                    \u2009=\u2009\u2212.15), and elevated WSS suppressed later PA (\n                    <jats:italic>\u03b2<\/jats:italic>\n                    \u2009=\u2009\u2212.18),\n                    <jats:styled-content>whereas<\/jats:styled-content>\n                    the corresponding cross\u2010lagged effects were not significant during the winter vacation (T2\u2009\u2192\u2009T3), underscoring context\u2010dependent temporality. No gender moderation was detected. These findings demonstrate that PA and WSS form a mutually reinforcing loop that is acutely sensitive to environmental structure, informing targeted, phase\u2010sensitive interventions that combine stigma reduction with PA promotion within naturalistic educational settings.\n                  <\/jats:p>","DOI":"10.1111\/aphw.70203","type":"journal-article","created":{"date-parts":[[2026,9,2]],"date-time":"2026-09-02T12:31:26Z","timestamp":1788352286000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Bidirectional associations and developmental trajectories between physical activity and weight self\u2010stigma among adolescents with high body weight\/obesity: A longitudinal study"],"prefix":"10.1111","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-6594-232X","authenticated-orcid":false,"given":"Kanglin","family":"Wang","sequence":"first","affiliation":[{"name":"School of Economics and Management Shanghai University of Sport  Shanghai China"},{"name":"School of Physical Education Wuhan University of Technology  Wuhan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zaihao","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Music and Dance Xihua University  Chengdu China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-0874-3932","authenticated-orcid":false,"given":"Jian","family":"Sun","sequence":"additional","affiliation":[{"name":"School of Music and Dance Xihua University  Chengdu China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-6449-7755","authenticated-orcid":false,"given":"Changkun","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Sports Science Honam University  Gwangju South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fen","family":"Qiu","sequence":"additional","affiliation":[{"name":"School of Physical Education Wuhan University of Technology  Wuhan China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,2]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph19020873"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.psychres.2025.116380"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.psych.52.1.1"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jecp.2025.106203"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1037\/dev0001580"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1177\/08862605211017257"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph16142558"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.3758\/s13428-020-01355-x"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1207\/S15328007SEM0902_5"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2047-6310.2012.00064.x"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10964-016-0500-8"},{"key":"e_1_2_11_13_1","first-page":"1","volume-title":"The ECPH Encyclopedia of Psychology","author":"Decan S.","year":"2024"},{"key":"e_1_2_11_14_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-020-73943-y"},{"key":"e_1_2_11_15_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40337-019-0265-z"},{"key":"e_1_2_11_16_1","volume-title":"Applied missing data analysis","author":"Enders C.
