Animal-based foods predicted higher PFAS: burrito (mean difference (MD): 1.45\u2009ng\/mL per IQR greater consumption, 95% CI: 0.56, 2.35) and cheese (MD: 0.87\u2009ng\/mL, 95% CI: 0.01, 1.76) intake were associated with higher PFHpA. Fish (OR: 1.55, 95% CI: 1.17, 2.36) and beef (OR: 1.44, 95% CI: 1.01, 2.12) intake were associated with greater odds of measuring PFBS above the detection limit. Using free or reduced-price school lunch programs predicted lower PFHpA (MD: \u20130.61\u2009ng\/mL, 95% CI: \u20131.13, \u20130.10), PFOA (MD: \u20130.22\u2009ng\/mL, 95% CI: \u20130.44, \u20130.01), and PFHxS (MD: \u20130.64\u2009ng\/mL, 95% CI: \u20130.64, \u20130.06). U.S. born children had lower PFHpA (MD: \u20130.54\u2009ng\/mL, 95% CI: \u20131.20, 0.09) and PFBS detection (OR: 0.25, 95% CI: 0.06, 0.88), and longer maternal residence in the U.S. was associated with lower PFBS detection (OR: 0.92, 95% CI: 0.85, 0.99).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Significance<\/jats:title>\n                    <jats:p>Greater animal-based food consumption was associated with higher blood PFAS concentrations in Hispanic children.

Little is known about culturally relevant predictors of PFAS exposure in this population. In a study of Hispanic children, we identified that consumption of animal-based foods was associated with higher blood PFAS concentrations. Social factors, like participation in school meal programs and acculturation measures, were associated with lower PFAS concentrations. These findings highlight the importance of the role of dietary and social factors in predicting PFAS exposure in Hispanic children. Our findings emphasize the need for studies to evaluate culturally relevant predictors of PFAS to inform future interventions.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1038\/s41370-026-00975-3","type":"journal-article","created":{"date-parts":[[2026,9,22]],"date-time":"2026-09-22T20:35:47Z","timestamp":1790109347000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dietary and social predictors of PFAS exposure in Hispanic children from Northern Virginia"],"prefix":"10.1038","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-6273-9766","authenticated-orcid":false,"given":"Rooshna","family":"Mohsin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roy R.","family":"Gerona","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sina","family":"Gallo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margaret T.","family":"Jones","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allison J.","family":"McKay","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robyn","family":"Mehlenbeck","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jenna R.","family":"Krall","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Virginia","family":"Espina","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Tomer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veronica G.","family":"Sanchez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lameck","family":"Chiwaka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael S.","family":"Bloom","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,9,22]]},"reference":[{"key":"975_CR1","doi-asserted-by":"publisher","first-page":"513","DOI":"10.1002\/ieam.258","volume":"7","author":"RC Buck","year":"2011","unstructured":"Buck RC, Franklin J, Berger U, Conder JM, Cousins IT, de Voogt P, et al.
