Low birth weight (&lt;2500\u2005g) occurred in 1 vegan newborn (3%) and in no omnivore newborns.

Differences between vegans and omnivores cannot be excluded. The study was underpowered and baseline differences limit group comparability, validity, and generalizability. The study highlights key parameters and underscores the need to maximize group comparability in future research.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/02601060261474598","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T13:49:51Z","timestamp":1785764991000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Maternal and newborn health in vegan and omnivore pregnancies: A prospective pilot study (PREGGIE)"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3761-4220","authenticated-orcid":false,"given":"Christian","family":"Koeder","sequence":"first","affiliation":[{"name":"Institute for Prevention and Cancer Epidemiology (IPE)"},{"name":"Research Institute for Plant-Based Nutrition (IFPE), Biebertal, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katharina","family":"Feuerlein","sequence":"additional","affiliation":[{"name":"University Witten\/Herdecke"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Virginie","family":"Stanislas","sequence":"additional","affiliation":[{"name":"Institute for Prevention and Cancer Epidemiology (IPE)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tim","family":"Zerback","sequence":"additional","affiliation":[{"name":"Research Institute for Plant-Based Nutrition (IFPE), Biebertal, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stine","family":"Weder","sequence":"additional","affiliation":[{"name":"Research Institute for Plant-Based Nutrition (IFPE), Biebertal, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alfred","family":"L\u00e4ngler","sequence":"additional","affiliation":[{"name":"Professur f\u00fcr integrative Kinder- und Jugendmedizin, University Witten\/Herdecke"},{"name":"Gemeinschaftskrankenhaus Herdecke, Klinik f\u00fcr Kinder- und Jugendmedizin, Herdecke, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ute","family":"Alexy","sequence":"additional","affiliation":[{"name":"University of Bonn"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus","family":"Keller","sequence":"additional","affiliation":[{"name":"Research Institute for Plant-Based Nutrition (IFPE), Biebertal, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,8,3]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00404-020-05561-y"},{"key":"e_1_3_3_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41372-020-00804-x"},{"key":"e_1_3_3_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00007611-198706000-00007"},{"key":"e_1_3_3_5_1","unstructured":"CSIS (2017) No Milk No Honey: Veganism in Israel and the West Bank.
