MS was measured by handgrip dynamometry. Participants were categorized into sex-specific quartiles of MS, while cases of GERD were identified by self-reported physician diagnosis. Logistic regression was used to calculate the odds ratios and 95% confidence intervals of GERD by quartiles of MS.<jats:bold>Results<\/jats:bold>: There were 112 GERD cases. Compared with the first quartile of MS, the odds ratios (95% confidence intervals) of GERD were 0.50 (0.27\u20130.95), 0.39 (0.20\u20130.75), and 0.55 (0.29\u20131.04) in the second, third, and fourth quartiles of MS, respectively, after adjusting for possible confounders including body mass index. In a joint analysis of MS and body mass index, participants were dichotomized into weak (first MS quartile) or strong (upper 3 MS quartiles) and normal weight, overweight, or obese. Compared with the weak\u2013obese group, odds ratios (95% confidence intervals) were 0.34 (0.14\u20130.80), 0.43 (0.16\u20131.13), 0.29 (0.12\u20130.68), 0.18 (0.06\u20130.55), and 0.07 (0.03\u20130.21) for the strong\u2013obese, weak\u2013overweight, strong\u2013overweight, weak\u2013normal weight, and strong\u2013normal weight.<jats:bold>Conclusions<\/jats:bold>: MS was independently and inversely associated with GERD in older adults.<\/jats:p>","DOI":"10.1123\/jpah.2021-0013","type":"journal-article","created":{"date-parts":[[2021,8,25]],"date-time":"2021-08-25T16:29:09Z","timestamp":1629908949000},"page":"1207-1214","source":"Crossref","is-referenced-by-count":7,"title":["Associations Between Muscular Strength and Gastroesophageal Reflux Disease in Older Adults"],"prefix":"10.1123","volume":"18","author":[{"given":"Bong Kil","family":"Song","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angelique G.","family":"Brellenthin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joey M.","family":"Saavedra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Duck-chul","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"key":"ref311","doi-asserted-by":"crossref","first-page":"684","DOI":"10.1093\/ageing\/afz068","article-title":"The association of grip strength with health outcomes does not differ if grip strength is used in absolute or relative terms: a prospective cohort study","volume":"48","author":"Ho","year":"2019","journal-title":"Age Ageing"},{"key":"ref761","doi-asserted-by":"crossref","first-page":"a439","DOI":"10.1136\/bmj.a439","article-title":"Association between muscular strength and mortality in men: prospective cohort study","volume":"337","author":"Ruiz","year":"2008","journal-title":"BMJ"},{"key":"ref241","doi-asserted-by":"crossref","first-page":"79","DOI":"10.1186\/1479-5868-8-79","article-title":"How many steps\/day are enough?
