Although there is evidence that malnutrition is associated with the decline of muscle quality in older adults, few analyses have considered important factors related to muscle quality.\n                    <jats:bold>Aim:<\/jats:bold>\n                    The purpose of this study was to determine the relationship between muscle quality and nutritional status in community-dwelling older adults, taking into account muscle mass, muscle strength, and amount of physical activity.\n                    <jats:bold>Methods:<\/jats:bold>\n                    This was a cross-sectional study. Data were obtained from a health checkup program in Japan. Participants were older adults aged \u226565 years living in the community who participated in the health checkup program. The data collected were echo intensity, scores on the Global Leadership Initiative on Malnutrition criteria, skeletal muscle mass, grip strength, physical activity level, and demographic data. Multiple regression analysis was used to examine the association between muscle quality and nutritional status.\n                    <jats:bold>Results:<\/jats:bold>\n                    Data were analyzed for 50 participants (mean age 77.62 years, standard deviation 6.16 years, 78.0% women). Multiple regression analysis showed that nutritional status affected muscle quality even when various factors were taken into account (B\u2009=\u20096.95, \u03b2\u2009=\u20090.31,\n                    <jats:italic>p\u2009=\u2009<\/jats:italic>\n                    0.04, 95% confidence interval: 0.01\u20130.62).\n                    <jats:bold>Conclusion:<\/jats:bold>\n                    The observed association suggests that providing nutritional support for older adults living in the community may be a useful strategy to maintain muscle quality.\n                  <\/jats:p>","DOI":"10.1177\/02601060241263377","type":"journal-article","created":{"date-parts":[[2024,7,25]],"date-time":"2024-07-25T07:37:54Z","timestamp":1721893074000},"page":"989-994","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Association between muscle quality and nutritional status among community-dwelling older adults: A cross-sectional study"],"prefix":"10.1177","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2548-5633","authenticated-orcid":false,"given":"Yuta","family":"Kubo","sequence":"first","affiliation":[{"name":"Faculty of Rehabilitation and Care, Seijoh University, Tokai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daiki","family":"Nakashima","sequence":"additional","affiliation":[{"name":"Faculty of Health Science, Naragakuen University, Nara, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoki","family":"Tomiyama","sequence":"additional","affiliation":[{"name":"Faculty of Rehabilitation and Care, Seijoh University, Tokai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kento","family":"Noritake","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Nihon Fukushi University, Handa, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyosuke","family":"Yorozuya","sequence":"additional","affiliation":[{"name":"Faculty of Rehabilitation and Care, Seijoh University, Tokai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshihito","family":"Tsubouchi","sequence":"additional","affiliation":[{"name":"Faculty of Health Science, Naragakuen University, Nara, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Terufumi","family":"Iitsuka","sequence":"additional","affiliation":[{"name":"Faculty of Health Science, Naragakuen University, Nara, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keisuke","family":"Fujii","sequence":"additional","affiliation":[{"name":"Faculty of Health Science, Suzuka University of Medical Science, Suzuka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,7,25]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.1152\/japplphysiol.90577.2008"},{"key":"e_1_3_3_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clnu.2022.08.010"},{"issue":"2","key":"e_1_3_3_4_1","first-page":"1","article-title":"Relationship between muscle mass and fraction of intramuscular adipose tissue of the quadriceps in older inpatients","volume":"17","author":"Akazawa N","unstructured":"Akazawa N, Kishi M, Hino T, et al.
