This study aimed to investigate the standardized prevalence and multidimensional risk factors associated with frailty among Korean community-dwelling older adults. We analyzed the baseline data of 2907 adults aged 70\u201384 years (mean age 75.8 \u00b1 3.9 years, 57.8% women) in the Korean Frailty and Aging Cohort Study. The Fried frailty phenotype was used to define frailty. Analyzed data included sociodemographic, physical, physical function, biological, lifestyle, health condition, medical condition, psychological, and social domains. Data were standardized using the national standard population composition ratio based on the Korean Population and Housing Census. The standardized prevalence of frailty and prefrailty was 7.9% (95% confidence interval (CI) 6.8\u20138.9%) and 47.0% (95% CI, 45.1\u201348.8%), respectively. The following 14 risk factors were significantly associated with frailty: at risk of malnutrition, sarcopenia, severe mobility limitation, poor social capital, rural dwellers, depressive symptoms, poor self-perceived health, polypharmacy, elevated high-sensitivity C-reactive protein, elevated glycosylated hemoglobin, low 25-hydroxy vitamin D level, longer Timed Up and Go, and low Short Physical Performance Battery score (p &lt; 0.05). Physiconutritional, psychological, sociodemographic, and medical factors are strongly associated with frailty.<\/jats:p>","DOI":"10.3390\/ijerph17217883","type":"journal-article","created":{"date-parts":[[2020,10,28]],"date-time":"2020-10-28T11:43:06Z","timestamp":1603885386000},"page":"7883","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":48,"title":["Prevalence of Physical Frailty and Its Multidimensional Risk Factors in Korean Community-Dwelling Older Adults: Findings from Korean Frailty and Aging Cohort Study"],"prefix":"10.3390","volume":"17","author":[{"given":"Heeeun","family":"Jung","sequence":"first","affiliation":[{"name":"Department of Biomedical Science and Technology, Graduate School, Kyung Hee University, Seoul 02447, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0852-8825","authenticated-orcid":false,"given":"Miji","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Biomedical Science and Technology, College of Medicine, East-West Medical Research Institute, Kyung Hee University, Seoul 02447, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8484-4750","authenticated-orcid":false,"given":"Yunhwan","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Preventive Medicine and Public Health, Ajou University School of Medicine, Suwon 16499, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6429-4461","authenticated-orcid":false,"given":"Chang Won","family":"Won","sequence":"additional","affiliation":[{"name":"Elderly Frailty Research Center, Department of Family Medicine, College of Medicine, Kyung Hee University, Seoul 02447, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"M146","DOI":"10.1093\/gerona\/56.3.M146","article-title":"Frailty in older adults: Evidence for a phenotype","volume":"56","author":"Fried","year":"2001","journal-title":"J.
