In this study, we aimed to evaluate the prevalence of different types of primary EMDs in patients referred for HREM and to further investigate the factors associated with EMDs. METHODS: In this cross-sectional study, all patients referred to the endoscopy section of Shariati Hospital during 2018-2019 (279 patients) were subjected to HREM and were evaluated according to their diagnosis, and the effect of each factor and each symptom on motility disorders was investigated. RESULTS: 84.5% (235) of the participants were diagnosed with at least one esophageal motility disorder; of them, achalasia was the most common form (52.6%). None of the predictive factors showed a statistically significant correlation with EMDs. However, regarding the symptoms, regurgitation and nocturnal cough were significantly more common in patients with EMD (P=0.001 and 0.009, respectively). CONCLUSION: This study demonstrates the high prevalence of EMDs in patients undergoing manometry. None of the factors studied, such as age, sex, diabetes, hypothyroidism, smoking, and alcohol and opium consumption, had a statistically significant correlation with EMDs. <\/jats:p>","DOI":"10.34172\/mejdd.2022.258","type":"journal-article","created":{"date-parts":[[2022,8,6]],"date-time":"2022-08-06T09:44:59Z","timestamp":1659779099000},"page":"70-76","update-policy":"https:\/\/doi.org\/10.34172\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Prevalence of Different Types of Primary Esophageal Motility Disorders and Their Associated Factors in Patients Referring to Shariati Hospital during 2018-2019"],"prefix":"10.34172","volume":"14","author":[{"given":"Mahan","family":"Assadian","sequence":"first","affiliation":[{"name":"Shariati Hospital, Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zahra","family":"Momayez Sanat","sequence":"additional","affiliation":[{"name":"Assistant Professor of Medicine, Digestive Diseases Research Institute, Shariati Hospital, Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hossein","family":"Asl Soleimani","sequence":"additional","affiliation":[{"name":"Associate Professor, Digestive Diseases Research Institute, Shariati Hospital, Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Javad","family":"Mikaeli","sequence":"additional","affiliation":[{"name":"Professor, Digestive Disease Research Institute, Shariati Hospital, Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"20123","published-online":{"date-parts":[[2022,1,30]]},"reference":[{"key":"R1","unstructured":"Goyal M, Nagalli S.
