{"doi":"10.1177/08982643231215475","title":"The Relationship Between Posttraumatic Stress Disorder and Alcohol Misuse and Smoking Among Aging Men Who Have Sex With Men: No Evidence of Exercise or Volunteering Impact","abstract":"OBJECTIVES: To determine if the association between posttraumatic stress disorder (PTSD) and substance use (alcohol misuse or smoking tobacco) is mediated/moderated by exercise or volunteering among aging (≥40 years) men who have sex with men (MSM), and if this mediation/moderation differs by HIV serostatus. METHODS: Multicenter AIDS Cohort Study data were used. Three datasets with PTSD measured during different time periods (10/1/2017-3/31/2018, 898 men; 4/1/2018-9/30/2018, 890 men; 10/1/2018-3/31/2019, 895 men) were analyzed. Longitudinal mediation analyses estimated the mediation effect of exercise and volunteering on the outcomes. RESULTS: Nine percent of MSM had evidence of PTSD. There was no statistically significant mediation effect of exercise or volunteering regardless of substance use outcome. The odds of smoking at a future visit among MSM with PTSD were approximately double those of MSM without PTSD. Results did not differ by HIV serostatus. DISCUSSION: There is a particular need for effective smoking cessation interventions for aging MSM with PTSD.","journal":"Journal of Aging and Health","year":2023,"id":379273,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":2,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9177,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":464136,"name":"Steven Meanley","orcid":"0000-0002-6098-9733","position":1,"is_corresponding":false},{"id":464139,"name":"Mark Brennan‐Ing","orcid":"0000-0001-9071-6659","position":2,"is_corresponding":false},{"id":464137,"name":"Sabina Haberlen","orcid":"0000-0002-9467-3454","position":3,"is_corresponding":false},{"id":404157,"name":"Deanna Ware","orcid":"0000-0001-5923-1864","position":4,"is_corresponding":false},{"id":518093,"name":"Roger Detels","orcid":"0000-0002-6622-9655","position":5,"is_corresponding":false},{"id":404162,"name":"M.
