Lack of awareness of STDs may lead to a delay in treatment. This study aimed to assess knowledge about STDs and the associated factors among dermatological patients. A cross-sectional study was conducted among 622 patients at Vietnam National Hospital of Dermatology and Venereology (NHD). Structured questionnaires were used to investigate the knowledge about STDs. A multivariate Tobit regression was employed to determine factors associated with knowledge about STDs. The percentage of patients knowing that syphilis was an STD was highest (57.8%), followed by herpes warts (57.7%) and HIV\/AIDS (57.4%). By contrast, 26.6% and 17.2% of patients knew that chlamydia and hepatitis C were STDs. The most commonly stated symptom of STDs was purulent genital (53.5%). Nearly two-thirds of participants were aware of the curability of STDs, and 34.7% knew about vaccines for STDs. Living with partners, young age, and acquired knowledge of STDs via the Internet, social networks, and health staff were positively related to having better knowledge about STDs. Based on the results of this study, peer education, informal conversations within clusters, mass community campaigns through the Internet and social networks, and the use of online health care providers should be promoted in order to improve awareness of STDs.<\/jats:p>","DOI":"10.3390\/ijerph16061080","type":"journal-article","created":{"date-parts":[[2019,3,27]],"date-time":"2019-03-27T05:03:12Z","timestamp":1553662992000},"page":"1080","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":41,"title":["Lack of Knowledge about Sexually Transmitted Diseases (STDs): Implications for STDs Prevention and Care among Dermatology Patients in an Urban City in Vietnam"],"prefix":"10.3390","volume":"16","author":[{"given":"Sau Huu","family":"Nguyen","sequence":"first","affiliation":[{"name":"National Hospital of Dermatology and Venereology, Hanoi 100000, Vietnam"},{"name":"Department of Dermatology and Venereology, Hanoi Medical University, Hanoi 100000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anh Kim","family":"Dang","sequence":"additional","affiliation":[{"name":"Institute for Global Health Innovations, Duy Tan University, Da Nang 550000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giang Thu","family":"Vu","sequence":"additional","affiliation":[{"name":"Center of Excellence in Evidence-Based Medicine, Nguyen Tat Thanh University, Ho Chi Minh City 700000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cuong Tat","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Institute for Global Health Innovations, Duy Tan University, Da Nang 550000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thu Hoai Thi","family":"Le","sequence":"additional","affiliation":[{"name":"National Hospital of Dermatology and Venereology, Hanoi 100000, Vietnam"},{"name":"Department of Dermatology and Venereology, Hanoi Medical University, Hanoi 100000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nu Thi","family":"Truong","sequence":"additional","affiliation":[{"name":"Center of Excellence in Behavioral Medicine, Nguyen Tat Thanh University, Ho Chi Minh City 700000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chi Linh","family":"Hoang","sequence":"additional","affiliation":[{"name":"Center of Excellence in Behavioral Medicine, Nguyen Tat Thanh University, Ho Chi Minh City 700000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tung Thanh","family":"Tran","sequence":"additional","affiliation":[{"name":"Center of Excellence in Evidence-Based Medicine, Nguyen Tat Thanh University, Ho Chi Minh City 700000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tung Hoang","family":"Tran","sequence":"additional","affiliation":[{"name":"Institute of Orthopaedic and Trauma Surgery, Vietnam\u2014Germany Hospital, Hanoi 100000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hai Quang","family":"Pham","sequence":"additional","affiliation":[{"name":"Institute for Global Health Innovations, Duy Tan University, Da Nang 550000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nam Gia","family":"Dao","sequence":"additional","affiliation":[{"name":"Center of Excellence in Evidence-Based Medicine, Nguyen Tat Thanh University, Ho Chi Minh City 700000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7827-8449","authenticated-orcid":false,"given":"Bach Xuan","family":"Tran","sequence":"additional","affiliation":[{"name":"Institute for Preventive Medicine and Public Health, Hanoi Medical University, Hanoi 100000, Vietnam"},{"name":"Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland, MD 21205, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7931-2116","authenticated-orcid":false,"given":"Carl A.","family":"Latkin","sequence":"additional","affiliation":[{"name":"Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland, MD 21205, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7092-9566","authenticated-orcid":false,"given":"Cyrus S.
