Data from the National HIV Behavioral Surveillance (NHBS) system high-risk heterosexuals (HET) cycle (2019) in Houston, Texas, was used to describe preventive care utilization and assess the relationship between healthcare utilization and sociodemographic characteristics. More than 47% reported having no usual source of healthcare, and 94.6% reported receiving no non-HIV STI testing in the past 12 months. Additionally, many sociodemographic factors were associated with healthcare utilization and having a usual source of healthcare. Future efforts should be targeted at increasing preventive healthcare utilization among high-risk vulnerable populations as well as implementing more preventive sexual healthcare services in the community health centers where these populations most frequently encounter healthcare.<\/jats:p>","DOI":"10.3390\/ijerph19084502","type":"journal-article","created":{"date-parts":[[2022,4,8]],"date-time":"2022-04-08T12:11:14Z","timestamp":1649419874000},"page":"4502","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Exploring Preventive Healthcare in a High-Risk Vulnerable Population"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4015-4912","authenticated-orcid":false,"given":"Trisha L.","family":"Amboree","sequence":"first","affiliation":[{"name":"Department of Management, Policy, and Community Health, The University of Texas Health Science Center School of Public Health, Houston, TX 77030, USA"},{"name":"Department of Epidemiology, Human Genetics and Environmental Sciences, The University of Texas Health Science Center School of Public Health, Houston, TX 77030, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jane R.","family":"Montealegre","sequence":"additional","affiliation":[{"name":"Dan L Duncan Comprehensive Cancer Center, Baylor College of Medicine, Houston, TX 77030, USA"},{"name":"Department of Pediatrics, Baylor College of Medicine, Houston, TX 77030, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kayo","family":"Fujimoto","sequence":"additional","affiliation":[{"name":"Department of Health Promotion and Behavioral Sciences, The University of Texas Health Science Center School of Public Health, Houston, TX 77030, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Osaro","family":"Mgbere","sequence":"additional","affiliation":[{"name":"Disease Prevention and Control Division, Houston Health Department, Houston, TX 77054, USA"},{"name":"Institute of Community Health, University of Houston College of Pharmacy, Houston, TX 77204, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0063-7856","authenticated-orcid":false,"given":"Charles","family":"Darkoh","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Human Genetics and Environmental Sciences, The University of Texas Health Science Center School of Public Health, Houston, TX 77030, USA"},{"name":"Microbiology and Infectious Diseases Program, University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences, Houston, TX 77030, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paige Padgett","family":"Wermuth","sequence":"additional","affiliation":[{"name":"Department of Management, Policy, and Community Health, The University of Texas Health Science Center School of Public Health, Houston, TX 77030, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"53","DOI":"10.4103\/2229-3485.106389","article-title":"Vulnerable population and methods for their safeguard","volume":"4","author":"Shivayogi","year":"2013","journal-title":"Perspect.
