Examine how sponsorship disclosures and nicotine warning labels (NWLs) affect responses to proe-cigarette Instagram posts among Mexican young adults. Materials and methods. In a 2 x 2 online experiment, Mexicans aged 18-24 (N= 699; 53% users and 47% nonusers of cigarettes or e-cigarettes who were susceptible to future use) were randomly assigned to view one of four Instagram posts: 1) control, 2) disclosure-only, 3) NWL-only, or 4) combination. Participants reported susceptibility to e-cigarettes, positive expectancies, and risk perceptions. Outcomes were analyzed via logistic regression (ref=control). Results. Compared to the control, participants exposed to the NWL alone or combined were less likely to be curious to try the e-cigarette (OR= 0.54, 95%CI 0.35,0.83; OR= 0.54, 95%CI 0.34,0.84), try it if offered by a friend (OR= 0.59, 95%CI 0.39,0.90; OR= 0.55, 95%CI 0.36,0.85), or expect to enjoy use (OR= 0.64, 95%CI 0.42,0.97; OR= 0.65, 95%CI 0.43,1.00). Risk perceptions did not differ; disclosures had no effect. The disclosure-only condition (vs control) increased willingness to try e-cigarettes among people who currently smoked or were susceptible to smoking (\u03b2= 0.84, p &lt;0.05). Conclusion. NWLs, but not sponsorship disclosures, reduce Mexican youth susceptibility and positive expectancies toward e-cigarettes.<\/jats:p>","DOI":"10.21149\/17611","type":"journal-article","created":{"date-parts":[[2026,6,25]],"date-time":"2026-06-25T23:49:09Z","timestamp":1782431349000},"page":"235-244","source":"Crossref","is-referenced-by-count":0,"title":["Evaluating strategies to reduce the effects of pro-e-cigarette social media posts in young adults"],"prefix":"10.21149","volume":"68","author":[{"given":"Lizeth","family":"Cruz-Jim\u00e9nez","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minji","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D\u00e8sir\u00e9e","family":"Vida\u00f1a-P\u00e9rez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aishwarya","family":"Khemkar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanwen","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diego F","family":"Leal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Inti","family":"Barrientos-Guti\u00e9rrez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James F","family":"Thrasher","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"8786","published-online":{"date-parts":[[2026,6,18]]},"container-title":["Salud P\u00fablica de M\u00e9xico"],"original-title":[],"link":[{"URL":"https:\/\/saludpublica.mx\/index.php\/spm\/article\/download\/17611\/12818","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/saludpublica.mx\/index.php\/spm\/article\/download\/17611\/12818","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,6,25]],"date-time":"2026-06-25T23:49:11Z","timestamp":1782431351000},"score":1,"resource":{"primary":{"URL":"https:\/\/saludpublica.mx\/index.php\/spm\/article\/view\/17611"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6,18]]},"references-count":0,"journal-issue":{"issue":"3 (may-jun)","published-online":{"date-parts":[[2026,6,18]]}},"URL":"https:\/\/doi.org\/10.21149\/17611","relation":{},"ISSN":["1606-7916","0036-3634"],"issn-type":[{"value":"1606-7916","type":"electronic"},{"value":"0036-3634","type":"print"}],"subject":[],"published":{"date-parts":[[2026,6,18]]}}}
