The aim of the present study was to examine the relationship between eating\/swallowing function and COVID-19 infection. Methods: Subjects were 44 inpatients with confirmed COVID-19 infection being treated for schizophrenia in a psychiatric ward. Eating function was assessed using the Food Intake Level Scale (FILS) before and after infection. We also evaluated age, comorbidities, COVID-19 hospital stay, obesity index, weight loss rate, and chlorpromazine equivalent. Results: Subjects had a mean age of 68.86 years. Pre-infection, 20 subjects had a FILS score of 7\u20139 (presence of eating\/swallowing disorder) and 24 subjects had a score of 10 (normal). Eating function after infection resolution showed decreasing FILS score compared to that before infection in 14 subjects (74.14 years). Six subjects (79.3 years) transitioned from oral feeding to parenteral feeding. A \u2265 10% weight loss during infection treatment was significantly associated with decreased eating function and a transition to parenteral feeding. Chlorpromazine equivalents, comorbidities, and number of days of hospitalization showed no associations with decreased eating function. Conclusions: Preventing malnutrition during treatment for COVID-19 infection is important for improving post-infection life prognosis and maintaining quality of life (QOL).<\/jats:p>","DOI":"10.3390\/nu13041113","type":"journal-article","created":{"date-parts":[[2021,3,29]],"date-time":"2021-03-29T04:29:14Z","timestamp":1616992154000},"page":"1113","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["COVID-19 Infection-Related Weight Loss Decreases Eating\/Swallowing Function in Schizophrenic Patients"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3815-5545","authenticated-orcid":false,"given":"Takeshi","family":"Kikutani","sequence":"first","affiliation":[{"name":"Division of Clinical Oral Rehabilitation, Graduate School of Life Dentistry, The Nippon Dental University, Tokyo 184-0011, Japan"},{"name":"Tama Oral Rehabilitation Clinic, The Nippon Dental University School of Life Dentistry, Tokyo 184-0011, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoko","family":"Ichikawa","sequence":"additional","affiliation":[{"name":"Tama Oral Rehabilitation Clinic, The Nippon Dental University School of Life Dentistry, Tokyo 184-0011, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eri","family":"Kitazume","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, The Nippon Dental University Hospital, Tokyo 102-8158, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arato","family":"Mizukoshi","sequence":"additional","affiliation":[{"name":"Tama Oral Rehabilitation Clinic, The Nippon Dental University School of Life Dentistry, Tokyo 184-0011, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Tohara","sequence":"additional","affiliation":[{"name":"Tama Oral Rehabilitation Clinic, The Nippon Dental University School of Life Dentistry, Tokyo 184-0011, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noriaki","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Tama Oral Rehabilitation Clinic, The Nippon Dental University School of Life Dentistry, Tokyo 184-0011, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fumiyo","family":"Tamura","sequence":"additional","affiliation":[{"name":"Tama Oral Rehabilitation Clinic, The Nippon Dental University School of Life Dentistry, Tokyo 184-0011, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manami","family":"Matsutani","sequence":"additional","affiliation":[{"name":"Musashino Central Hospital, Tokyo 184-8585, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junko","family":"Onishi","sequence":"additional","affiliation":[{"name":"Musashino Central Hospital, Tokyo 184-8585, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eiichiro","family":"Makino","sequence":"additional","affiliation":[{"name":"Musashino Central Hospital, Tokyo 184-8585, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,29]]},"reference":[{"key":"ref_1","unstructured":"GBD Disease and Injury Incidence and Prevalence Collaborators (2018).
