This cross-sectional study evaluated taste and smell in patients categorized into different age groups (&lt;65&gt; years) and different care need, with and without dry mouth. Of the 185 patients included, 119 were classified as \u201cdry mouth\u201d and 66 as \u201cwithout dry mouth\u201d. Overall, 103 (55.7%) were female and 37 (20%) needed care. There was no difference between \u201cdry mouth\u201d and \u201cwithout dry mouth\u201d regarding identification of odors or tastes, but a difference in the number of correctly identified odors and tastes in favor of \u201cwithout care need\u201d patients (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). The ability to identify smells and tastes was negatively influenced by age, number of medications, and number of comorbidities, but subjective dry mouth had no impact. According to our results, subjective dry mouth is not a risk factor for an impaired ability to recognize smells and tastes. However, care need representing age, the number of medications taken, and the number of chronic comorbidities is a risk indicator.<\/jats:p>","DOI":"10.1038\/s41598-021-99978-3","type":"journal-article","created":{"date-parts":[[2021,10,14]],"date-time":"2021-10-14T10:09:16Z","timestamp":1634206156000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Care need and dry mouth as risk indicators for impaired taste and smell"],"prefix":"10.1038","volume":"11","author":[{"given":"Mara-Zoe","family":"Hummelsheim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefanie","family":"Hamacher","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Hagemeier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael Johannes","family":"Noack","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna Greta","family":"Barbe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,10,14]]},"reference":[{"issue":"10","key":"99978_CR1","doi-asserted-by":"publisher","first-page":"877","DOI":"10.1007\/s40266-018-0588-5","volume":"35","author":"AG Barbe","year":"2018","unstructured":"Barbe, A.
