Sociodemographic disparities in accessing CR persist and could be related to the distance between where patients live and where CR facilities are located. Our objective is to determine the association between sociodemographic characteristics and geographic proximity to CR facilities.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Methods and Results<\/jats:title>\n            <jats:p xml:lang=\"en\">We identified actively operating CR facilities across Los Angeles County and used multivariable Poisson regression to examine the association between sociodemographic characteristics of residential proximity to the nearest CR facility. We also calculated the proportion of residents per area lacking geographic proximity to CR facilities across sociodemographic characteristics, from which we calculated prevalence ratios. We found that racial and ethnic minorities, compared with non\u2010Hispanic White individuals, more frequently live \u22655 miles from a CR facility. The greatest geographic disparity was seen for non\u2010Hispanic Black individuals, with a 2.73 (95% CI, 2.66\u20132.79) prevalence ratio of living at least 5 miles from a CR facility. Notably, the municipal region with the largest proportion of census tracts comprising mostly non\u2010White residents (those identifying as Hispanic or a race other than White), with median annual household income &lt;$60\u2009000, contained no CR facilities despite ranking among the county's highest in population density.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p xml:lang=\"en\">Racial, ethnic, and socioeconomic characteristics are significantly associated with lack of geographic proximity to a CR facility. Interventions targeting geographic as well as nongeographic factors may be needed to reduce disparities in access to exercise\u2010based CR programs. Such interventions could increase the potential of CR to benefit patients at high risk for developing adverse cardiovascular outcomes.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/jaha.121.026472","type":"journal-article","created":{"date-parts":[[2022,9,8]],"date-time":"2022-09-08T10:35:56Z","timestamp":1662633356000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":19,"title":["Disparities in Geographic Access to Cardiac Rehabilitation in Los Angeles County"],"prefix":"10.1161","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0587-1572","authenticated-orcid":false,"given":"Joseph E.","family":"Ebinger","sequence":"first","affiliation":[{"name":"Department of Cardiology Smidt Heart Institute, Cedars\u2010Sinai Medical Center Los Angeles CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roy","family":"Lan","sequence":"additional","affiliation":[{"name":"College of Medicine University of Tennessee Health Science Center Memphis TN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5389-1148","authenticated-orcid":false,"given":"Matthew P.","family":"Driver","sequence":"additional","affiliation":[{"name":"Department of Cardiology Smidt Heart Institute, Cedars\u2010Sinai Medical Center Los Angeles CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Parker","family":"Rushworth","sequence":"additional","affiliation":[{"name":"Department of Medicine Cedars\u2010Sinai Medical Center Los Angeles CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Luong","sequence":"additional","affiliation":[{"name":"Department of Cardiology Smidt Heart Institute, Cedars\u2010Sinai Medical Center Los Angeles CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5283-8556","authenticated-orcid":false,"given":"Nancy","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Cardiology Smidt Heart Institute, Cedars\u2010Sinai Medical Center Los Angeles CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7720-8019","authenticated-orcid":false,"given":"Trevor\u2010Trung","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Cardiology Smidt Heart Institute, Cedars\u2010Sinai Medical Center Los Angeles CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9592-602X","authenticated-orcid":false,"given":"Sarah","family":"Sternbach","sequence":"additional","affiliation":[{"name":"Department of Cardiology Smidt Heart Institute, Cedars\u2010Sinai Medical Center Los Angeles CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy","family":"Hoang","sequence":"additional","affiliation":[{"name":"Department of Cardiology Smidt Heart Institute, Cedars\u2010Sinai Medical Center Los Angeles CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacqueline","family":"Diaz","sequence":"additional","affiliation":[{"name":"Department of Cardiology Smidt Heart Institute, Cedars\u2010Sinai Medical Center Los Angeles CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mallory","family":"Heath","sequence":"additional","affiliation":[{"name":"Department of Cardiology Smidt Heart Institute, Cedars\u2010Sinai Medical Center Los Angeles CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4215-9218","authenticated-orcid":false,"given":"Brian L.","family":"Claggett","sequence":"additional","affiliation":[{"name":"Cardiovascular Division Brigham and Women\u2019s Hospital Boston MA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9933-5155","authenticated-orcid":false,"given":"C.
