Methods: A two-wave prospective survey with a six-month interval was conducted among 980 community-dwelling older adults in Zhengzhou, China. Baseline data were collected in September 2024, and follow-up data were collected in March 2025. Physical exercise was assessed using the Physical Activity Rating Scale-3, depressive symptoms using the 10-item Center for Epidemiologic Studies Depression Scale, loneliness using the 8-item UCLA Loneliness Scale, and cognitive emotion regulation strategies using the short version of the Cognitive Emotion Regulation Questionnaire. Cross-lagged models were used to examine the residual prospective association between physical exercise and depressive symptoms. A two-wave prospective explanatory model was then tested to examine the role of follow-up loneliness, and moderated explanatory (half-longitudinal) analyses were conducted using baseline adaptive and maladaptive cognitive emotion regulation strategies as moderators. Results: Baseline physical exercise was significantly associated with lower depressive symptoms at follow-up after controlling for baseline depressive symptoms and covariates (\u03b2 = \u22120.182, p &lt; 0.001). In contrast, baseline depressive symptoms were not significantly associated with follow-up physical exercise (\u03b2 = \u22120.016, p = 0.633). Baseline physical exercise was negatively associated with follow-up loneliness (\u03b2 = \u22120.267, p &lt; 0.001), and follow-up loneliness was positively associated with follow-up depressive symptoms (\u03b2 = 0.324, p &lt; 0.001). The indirect association through follow-up loneliness was significant (indirect effect = \u22120.087, 95% CI [\u22120.112, \u22120.065]). Baseline adaptive cognitive emotion regulation strategies strengthened the association between physical exercise and lower loneliness (interaction \u03b2 = \u22120.076, p &lt; 0.001), whereas baseline maladaptive strategies weakened this association (interaction \u03b2 = 0.059, p = 0.004). Conclusions: Self-reported physical exercise was prospectively associated with fewer depressive symptoms among older adults six months later. This association was statistically accounted for, in part, by lower follow-up loneliness, and baseline cognitive emotion regulation strategies were associated with the strength of the exercise\u2013loneliness association. Because this study used a two-wave observational design with the explanatory variable and outcome measured at the same follow-up wave, the findings should be interpreted as prospective associations rather than evidence of causal or temporal mediation.<\/jats:p>","DOI":"10.3390\/bs16071108","type":"journal-article","created":{"date-parts":[[2026,7,3]],"date-time":"2026-07-03T09:34:11Z","timestamp":1783071251000},"page":"1108","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Longitudinal Association Between Physical Exercise and Depressive Symptoms in Older Adults: The Prospective Explanatory Role of Loneliness and the Moderating Role of Cognitive Emotion Regulation"],"prefix":"10.3390","volume":"16","author":[{"given":"Renjie","family":"Ma","sequence":"first","affiliation":[{"name":"School of Marxism, Zhengzhou University, Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haozhen","family":"Li","sequence":"additional","affiliation":[{"name":"School of Kinesiology and Physical Education, Zhengzhou University, Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7741-9274","authenticated-orcid":false,"given":"Qiuhan","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Kinesiology and Physical Education, Zhengzhou University, Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"217","DOI":"10.1016\/j.cpr.2009.11.004","article-title":"Emotion-regulation strategies across psychopathology: A meta-analytic review","volume":"30","author":"Aldao","year":"2010","journal-title":"Clinical Psychology Review"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"77","DOI":"10.1016\/S0749-3797(18)30622-6","article-title":"Screening for depression in well older adults: Evaluation of a short form of the CES-D (Center for Epidemiologic Studies Depression Scale)","volume":"10","author":"Andresen","year":"1994","journal-title":"American Journal of Preventive Medicine"},{"key":"ref_3","doi-asserted-by":"crossref","unstructured":"Bahadori, F., Asadollahi, A., Ghajari, O., and Yarelahi, M.
