The main aim of this study was the determination of the total iodine content of breast milk (including colostrum and mature milk). A secondary objective was to assess the influence of factors such as the type of delivery, hypothyroidism, gestational diabetes or the stage of lactation on this parameter. The study materials were colostrum and milk after 1 (n = 14), 2 and 3 months (n = 8) of lactation with a range of iodine concentrations (\u00b5g\/L): 195\u20131648 and 170\u2013842, 174\u2013650 and 273\u2013751, respectively. Iodine was determined using the inductively coupled plasma mass spectrometry (ICP-MS). Multivariate statistical analysis revealed, e.g., that delivery by caesarean section or dose of L-thyroxine taken by women to normalise thyroid hormones, had a significant effect on iodine concentrations in breast milk. Further research aimed at assessing the quality of breast milk should also include determining the factors influencing it.<\/jats:p>","DOI":"10.3390\/foods13142241","type":"journal-article","created":{"date-parts":[[2024,7,17]],"date-time":"2024-07-17T08:48:29Z","timestamp":1721206109000},"page":"2241","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The Assessment of Iodine Concentrations in Colostrum and Breast Milk Using ICP-MS: The Impact of Delivery Type, Thyroid Function and Gestational Diabetes\u2014A Pilot Study"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4819-9085","authenticated-orcid":false,"given":"Jadwiga","family":"Kryczyk-Kozio\u0142","sequence":"first","affiliation":[{"name":"Department of Food Chemistry and Nutrition, Faculty of Pharmacy, Jagiellonian University Medical College, Medyczna 9, 30-688 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulina","family":"Moniak","sequence":"additional","affiliation":[{"name":"Department of Food Chemistry and Nutrition, Faculty of Pharmacy, Jagiellonian University Medical College, Medyczna 9, 30-688 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5101-036X","authenticated-orcid":false,"given":"Pawe\u0142","family":"Zagrodzki","sequence":"additional","affiliation":[{"name":"Department of Food Chemistry and Nutrition, Faculty of Pharmacy, Jagiellonian University Medical College, Medyczna 9, 30-688 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryszard","family":"Lauterbach","sequence":"additional","affiliation":[{"name":"Department of Neonatology, Jagiellonian University Hospital, Kopernika 23, 31-501 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hubert","family":"Huras","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Perinatology, Jagiellonian University Hospital, Kopernika 23, 31-501 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magdalena","family":"Sta\u015bkiewicz","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Perinatology, Jagiellonian University Hospital, Kopernika 23, 31-501 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miros\u0142aw","family":"Kro\u015bniak","sequence":"additional","affiliation":[{"name":"Department of Food Chemistry and Nutrition, Faculty of Pharmacy, Jagiellonian University Medical College, Medyczna 9, 30-688 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4821-4492","authenticated-orcid":false,"given":"Pawe\u0142","family":"Pa\u015bko","sequence":"additional","affiliation":[{"name":"Department of Food Chemistry and Nutrition, Faculty of Pharmacy, Jagiellonian University Medical College, Medyczna 9, 30-688 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Podsiad\u0142y","sequence":"additional","affiliation":[{"name":"Institute of Physics, Faculty of Natural Sciences, Jan Kochanowski University, Uniwersytecka 7, 25-406 Kielce, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justyna","family":"Dobrowolska-Iwanek","sequence":"additional","affiliation":[{"name":"Department of Food Chemistry and Nutrition, Faculty of Pharmacy, Jagiellonian University Medical College, Medyczna 9, 30-688 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1341","DOI":"10.1002\/fsn3.694","article-title":"Iodine Consumption and Cognitive Performance: Confirmation of Adequate Consumption","volume":"6","author":"Choudhry","year":"2018","journal-title":"Food Sci.
