This study proposes a modified version of the Mini Nutritional Assessment (MNA) to assess the risk of malnutrition among older Mexicans adults in the Mexican Health and Aging Study (MHAS). Data comes from the 2012, 2015, and 2018 waves of the MHAS, a nationally representative study of Mexicans aged 50 and older. The sample included 13,338 participants and a subsample of 1911 with biomarker values. ROC analysis was used to calculate the cut point for malnutrition risk. This cut point was compared to the definition of malnutrition from the ESPEN criteria, BMI, low hemoglobin, or low cholesterol. Logistic regression was used to assess predictors of malnutrition risk. A score of 10 was the optimal cut point for malnutrition risk in the modified MNA. This cut point had high concordance to identify malnutrition risk compared to the ESPEN criteria (97.7%) and had moderate concordance compared to BMI only (78.6%), and the biomarkers of low hemoglobin (56.1%) and low cholesterol (54.1%). Women, those older than 70, those with Seguro Popular health insurance, and those with fair\/poor health were more likely to be malnourished. The modified MNA is an important tool to assess malnutrition risk in future studies using MHAS data.<\/jats:p>","DOI":"10.3390\/nu13051615","type":"journal-article","created":{"date-parts":[[2021,5,12]],"date-time":"2021-05-12T22:46:14Z","timestamp":1620859574000},"page":"1615","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Malnutrition Risk among Older Mexican Adults in the Mexican Health and Aging Study"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2019-6453","authenticated-orcid":false,"given":"Jaqueline C.","family":"Avila","sequence":"first","affiliation":[{"name":"Center for Alcohol and Addiction Studies, School of Public Health, Brown University, Providence, RI 02903, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rafael","family":"Samper-Ternent","sequence":"additional","affiliation":[{"name":"Sealy Center on Aging, University of Texas Medical Branch, Galveston, TX 77555, USA"},{"name":"Department of Internal Medicine, Division of Geriatrics, University of Texas Medical Branch, Galveston, TX 77555, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7287-0660","authenticated-orcid":false,"given":"Rebeca","family":"Wong","sequence":"additional","affiliation":[{"name":"Sealy Center on Aging, University of Texas Medical Branch, Galveston, TX 77555, USA"},{"name":"Department of Preventive Medicine and Population Health, University of Texas Medical Branch, Galveston, TX 77555, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"304","DOI":"10.1177\/0898264314549661","article-title":"Nutritional assessment and factors associated to malnutrition in older adults: A cross-sectional study in Bogot\u00e1, Colombia","volume":"27","author":"Arciniegas","year":"2015","journal-title":"J.
