Currently, there is currently some understanding of PSD risk factors, but its protective factors remain largely unknown.<\/jats:p><jats:p><jats:bold>Objective:<\/jats:bold> To analyze the effects of acupuncture (AP) on dysphagia in stroke patients and explore its potential as a preventive therapy.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> Patients with a diagnosis of stroke from 2010 to 2019 were selected and followed until 2020, utilizing factors such as age, gender, stroke location, stroke type, and baseline comorbidity. To compare the incidence of dysphagia, equal numbers of stroke patients treated with and without AP (<jats:italic>n<\/jats:italic> = 1,809) were matched by 1:1 propensity scoring. The Cox proportional hazards model and Kaplan-Meier method were used to assess the risk of dysphagia as an outcome measure.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> The stroke patients treated with AP had a lower risk of dysphagia after adjusting for age, gender, stroke location, stroke type, and baseline comorbidity [adjusted hazard ratio (AHR) = 0.43, 95% confidence interval = 0.37\u20130.49] compared with those in the non-AP cohort. AP also decreased the risk of PSD among different gender groups. The risk ratios were AHR = 0.45 and AHR = 0.33 for males and females, respectively. AP also reduced the risk for PSD among different age groups. The risk ratios were AHR = 0.20, AHR = 0.37, AHR = 0.41, and AHR = 0.45 for the 18\u201339, 40\u201359, 60\u201379, and &amp;gt;80 years-old groups. Regarding stroke types (ischemic, hemorrhagic, and mixed type), patients treated with AP had a lower risk (AHR = 0.47, 0.28 and 0.17, respectively). With respect to stroke location, the risk of PSD in AP-treated patients was decreased regardless of location: brain stem (AHR = 0.41), diencephalon (AHR = 0.13), or multiple lesions (AHR = 0.40), the risk of PSD in AP-treated patients was decreased. For all baseline comorbidities, AP attenuated the risk of dysphagia. The cumulative incidence of dysphagia was remarkably lower in the AP group than in the non-AP group (log-rank test, <jats:italic>P<\/jats:italic> = 0.000).<\/jats:p><jats:p><jats:bold>Limitations:<\/jats:bold> First, this was a single-center clinical retrospective study. Second, we did not classify the severity of stroke and dysphagia. Third, all data were extracted manually. Lastly, the sample size was relatively small. Thus, future studies with larger sample sizes are warranted to verify our findings.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> Acupuncture treatment attenuates the risk of dysphagia in stroke patients. Future research should increase the sample size and elaborate further on the details of the AP protocol.<\/jats:p>","DOI":"10.3389\/fnins.2021.791964","type":"journal-article","created":{"date-parts":[[2022,1,6]],"date-time":"2022-01-06T05:54:29Z","timestamp":1641448469000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Acupuncture Reduces the Risk of Dysphagia in Stroke Patients: A Propensity Score-Matched Cohort Study"],"prefix":"10.3389","volume":"15","author":[{"given":"Xuan","family":"Qiu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao-Jie","family":"Yao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheng-Nan","family":"Han","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun-Yun","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zeng-Jian","family":"Ou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tian-Shi","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,1,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"870","DOI":"10.20344\/amp.9183","article-title":"Efeitos da terapia da fala em pacientes internados com disfagia p\u00f3s-acidente cerebrovascular: revis\u00e3o sistem\u00e1tica de estudos observacionais [Effects of speech therapy in hospitalized patients with post-stroke dysphagia: a systematic review of observational studies].","volume":"30","author":"Andrade","year":"2017","journal-title":"Acta Med.
