Physical fitness and adherence to physical activity (PA) are associated with better glycaemic stability and diabetes management. However, the relationship with SWB is not yet understood. The aim of the study was to determine the relationship between physical fitness, PA, and SWB over two years in youths with T1DM. This longitudinal study involved 83 participants (aged 6\u201318\u2009years; 44.6% girls) from the Diactive\u20101 Cohort. Physical fitness was assessed by spirometry (peak oxygen consumption) and dynamometry (handgrip strength). PA domains were measured using triaxial accelerometers, whereas the number of days participating in muscle\u2010strengthening activities was assessed using a question. The\n                    <jats:italic>Cuestionario \u00danico de Bienestar Escolar<\/jats:italic>\n                    was used to determine SWB. Glycaemic stability was determined when glycosylated hemoglobin &lt;\u20097%, coefficient of variability \u2264\u200936%, and time\u2010in\u2010range target &gt;\u200970% were met. The linear mixed models used considered three assessments and subject variability, showing significant associations between overall physical fitness (unstandardized beta coefficient [\n                    <jats:italic>B<\/jats:italic>\n                    ]\u2009=\u20091.778, 95% confidence interval [CI] 0.413\u20133.158;\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.012) and total PA (\n                    <jats:italic>B<\/jats:italic>\n                    \u2009=\u20090.034, 95% CI 0.005\u20130.063;\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.020) with SWB. Although time did not moderate the association with physical fitness (\n                    <jats:italic>p\u2009=<\/jats:italic>\n                    \u20090.116), this was true for PA only in the second year (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.020).

In conclusion, physical fitness and PA are associated with greater SWB in young people with T1DM, which may play a role in the psychological aspects of disease management.\n                  <\/jats:p>","DOI":"10.1111\/sms.70033","type":"journal-article","created":{"date-parts":[[2025,3,8]],"date-time":"2025-03-08T09:27:36Z","timestamp":1741426056000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Physical Fitness and Activity Levels as Predictors of Subjective Well\u2010Being in Youths With Type 1 Diabetes Mellitus: A 2\u2010Year Longitudinal Analysis of the Diactive\u20101 Cohort Study"],"prefix":"10.1111","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0210-2866","authenticated-orcid":false,"given":"Jacinto","family":"Mu\u00f1oz\u2010Pardeza","sequence":"first","affiliation":[{"name":"Navarrabiomed, Hospital Universitario de Navarra Universidad P\u00fablica de Navarra (UPNA)  Pamplona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7412-7624","authenticated-orcid":false,"given":"Jos\u00e9 Francisco","family":"L\u00f3pez\u2010Gil","sequence":"additional","affiliation":[{"name":"One Health Research Group Universidad de Las Am\u00e9ricas  Quito Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5443-5788","authenticated-orcid":false,"given":"Nidia","family":"Huerta\u2010Uribe","sequence":"additional","affiliation":[{"name":"Navarrabiomed, Hospital Universitario de Navarra Universidad P\u00fablica de Navarra (UPNA)  Pamplona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-7221-1731","authenticated-orcid":false,"given":"Ignacio","family":"Hormaz\u00e1bal\u2010Aguayo","sequence":"additional","affiliation":[{"name":"Navarrabiomed, Hospital Universitario de Navarra Universidad P\u00fablica de Navarra (UPNA)  Pamplona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9311-6576","authenticated-orcid":false,"given":"Rodrigo","family":"Y\u00e1\u00f1ez\u2010Sep\u00falveda","sequence":"additional","affiliation":[{"name":"Faculty of Education and Social Sciences Universidad Andres Bello  Vi\u00f1a del Mar Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9691-5998","authenticated-orcid":false,"given":"Yasmin","family":"Ezzatvar","sequence":"additional","affiliation":[{"name":"Lifestyle Factors With Impact on Ageing and Overall Health (LAH) Research Group, Department of Nursing University of Val\u00e8ncia  Valencia Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1506-4272","authenticated-orcid":false,"given":"Mikel","family":"Izquierdo","sequence":"additional","affiliation":[{"name":"Navarrabiomed, Hospital Universitario de Navarra Universidad P\u00fablica de Navarra (UPNA)  Pamplona Spain"},{"name":"CIBER of Frailty and Healthy Aging (CIBERFES) Instituto de Salud Carlos III (ISCIII)  Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1397-7182","authenticated-orcid":false,"given":"Antonio","family":"Garc\u00eda\u2010Hermoso","sequence":"additional","affiliation":[{"name":"Navarrabiomed, Hospital Universitario de Navarra Universidad P\u00fablica de Navarra (UPNA)  Pamplona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,3,5]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1037\/0033\u20102909.95.3.542"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11205\u2010012\u20100076\u2010y"},{"key":"e_1_2_10_4_1","volume-title":"World Happiness Report","author":"De Neve J.
