To analyze the density and inequality of human resources in nutrition (HRN) in the Mexican\u00a0 public health system, as well as their evolution between\u00a0 2019 and 2023. Materials and methods. An ecological\u00a0 study was conducted with secondary information\u00a0 sources for 2019 and 2023. The density of HRN per\u00a0 100,000 inhabitants was estimated, based on the total\u00a0 population, and its distribution was analyzed according\u00a0 to social security institution, level of care, and federative\u00a0 entity. In addition, the density of HRN for adults with\u00a0 overweight or obesity (OoO) was estimated for 2023. To\u00a0 estimate the inequality in the state distribution of HRN,\u00a0 the concentration index (CI) was used, and the\u00a0 marginalization index as a stratifier. Results. In Mexico,\u00a0 the density of HRN increased from 5.9 in 2019 to 6.9 per\u00a0 100,000 inhabitants in 2023; however, this increase was\u00a0 unequal among federative entities, institutions, and\u00a0 levels of care. In second and third-level care units, the\u00a0 density reached up to 22.41 HRN per 100,000 inhabitants, while in the first level it was 2.0. There is a higher\u00a0 concentration of HRN in entities with lower\u00a0 marginalization (CI=0.13 in 2019; CI=0.11 in 2023), units\u00a0 for the population with social security (CI=0.36 in 2019; CI=0.33 in 2023), and second and third levels (CI=0.20 in 2019; CI=0.18 in 2023). Conclusions. In Mexico, between\u00a0 2019 and 2023, the density of HRN increased, but state- level and by level of care inequalities persist. Strengthening its planning and distribution, particularly\u00a0 at the first level of care, is essential to respond to the nutritional and epidemiological needs of the country.<\/jats:p>","DOI":"10.17843\/rpmesp.2026.433.16389","type":"journal-article","created":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T21:12:11Z","timestamp":1791234731000},"page":"338-48","source":"Crossref","is-referenced-by-count":0,"title":["Mucha obesidad, poco personal: la desigualdad de los recursos humanos en nutrici\u00f3n en M\u00e9xico\u00a0 (2019-2023)","Much obesity, scarce staff: the inequality of human resources in nutrition in Mexico (2019-2023)"],"prefix":"10.17843","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3685-7423","authenticated-orcid":false,"given":"Elizabeth","family":"Hoyos-Loya","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9627-3430","authenticated-orcid":false,"given":"Jair","family":"Ya\u00f1ez-Santaolalla","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4987-3684","authenticated-orcid":false,"given":"Mar\u00eda Cecilia","family":"Gonz\u00e1lez-Robledo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-1729-5955","authenticated-orcid":false,"given":"David A.","family":"Barrera-N\u00fa\u00f1ez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9716-7274","authenticated-orcid":false,"given":"M\u00f3nica","family":"Ancira-Moreno","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-6974-6031","authenticated-orcid":false,"given":"Karla Mar\u00eda","family":"Armend\u00e1riz-Acosta","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9763-4143","authenticated-orcid":false,"given":"Hortensia","family":"Reyes-Morales","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9172-2302","authenticated-orcid":false,"given":"Jaqueline E.","family":"Alcalde Rabanal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7920","published-online":{"date-parts":[[2026,9,30]]},"container-title":["Revista Peruana de Medicina Experimental y Salud P\u00fablica"],"original-title":[],"link":[{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/download\/16389\/6323","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/download\/16389\/6323","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T21:12:15Z","timestamp":1791234735000},"score":1,"resource":{"primary":{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/view\/16389"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,30]]},"references-count":0,"URL":"https:\/\/doi.org\/10.17843\/rpmesp.2026.433.16389","relation":{},"ISSN":["1726-4642","1726-4634"],"issn-type":[{"value":"1726-4642","type":"electronic"},{"value":"1726-4634","type":"print"}],"subject":[],"published":{"date-parts":[[2026,9,30]]}}}
