However, few studies have examined differences among those within this broad category. This study examined characteristics of AYAs who used e-cigarettes at a low frequency (within the last 3\u2009months but &lt;6\u2009days out of the past 30\u2009days) and those who used e-cigarettes at a high frequency (6+\u2009days out of the past 30\u2009days).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We conducted cross-sectional analyses among 551 Ohio AYAs (15- to 24-year-olds) who reported using an e-cigarette to vape nicotine in the past 3\u2009months.

In the multivariable analysis, reported nicotine dependence (Odds Ratio [OR]: 7.0, 95% CI: 4.8, 10.3) and current other tobacco product use (OR: 1.8, 95% CI: 1.1, 2.9) were associated with high-frequency e-cigarette use.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Our results suggest that frequency of use is an important characteristic in understanding AYA e-cigarette use. Any use in the past 30\u2009days may not be sensitive enough to understand dependence and tobacco-use behaviors. Further characterizing \u201ccurrent\u201d e-cigarette use by frequency of use may provide meaningful information for public health professionals to better target intervention and cessation efforts to AYAs.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/29767342231214115","type":"journal-article","created":{"date-parts":[[2024,1,2]],"date-time":"2024-01-02T05:42:42Z","timestamp":1704174162000},"page":"232-239","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Demographic and Behavioral Differences Between Adolescents and Young Adults Who Use E-Cigarettes at Low and High Frequency"],"prefix":"10.1177","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0673-6153","authenticated-orcid":false,"given":"Jill M.","family":"Singer","sequence":"first","affiliation":[{"name":"College of Public Health, The Ohio State University, Columbus, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alayna P.","family":"Tackett","sequence":"additional","affiliation":[{"name":"College of Medicine, The Ohio State University, Columbus, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth G.","family":"Klein","sequence":"additional","affiliation":[{"name":"College of Public Health, The Ohio State University, Columbus, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"Lu","sequence":"additional","affiliation":[{"name":"College of Public Health, The Ohio State University, Columbus, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dylan D.","family":"Wagner","sequence":"additional","affiliation":[{"name":"Department of Psychology, The Ohio State University, Columbus, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Loren E.","family":"Wold","sequence":"additional","affiliation":[{"name":"College of Medicine, The Ohio State University, Columbus, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megan E.","family":"Roberts","sequence":"additional","affiliation":[{"name":"College of Public Health, The Ohio State University, Columbus, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,1,2]]},"reference":[{"key":"bibr1-29767342231214115","unstructured":"U.S. Department of Health and Human Services.
