| description | The role of milk and dairy products in supplying iodine to pregnant women is unknown in Portugal. The aim of this study was to evaluate the association between milk and dairy product consumption and the iodine status of pregnant women in the IoMum cohort of the Oporto region. Pregnant women were recruited between 10 and 13 weeks of gestation, when they provided a spot urine sample and information on lifestyle and intake of iodine-rich foods. Urinary iodine concentration (UIC) was determined by inductively coupled plasma MS. A total of 468 pregnant women (269 iodine supplement users and 199 non-supplement users) were considered eligible for analysis. Milk (but not yogurt or cheese) intake was positively associated with UIC, in the whole population (P = 0·02) and in the non-supplement users (P = 0·002), but not in the supplement users (P = 0·29). In non-supplement users, adjusted multinomial logistic regression analysis showed that milk consumption |

In non-supplement users, adjusted multinomial logistic regression analysis showed that milk consumption <3 times/month was associated with a five times increased risk of having UIC < 50 µg/l when compared with milk consumption ≥2 times/d (OR 5·4; 95 % CI 1·55, 18·78; P = 0·008). The highest UIC was observed in supplement users who reported consuming milk once per d (160 µg/l). Milk, but not yogurt or cheese, was positively associated with iodine status of pregnant women. Despite the observed positive association, daily milk consumption may not be sufficient to ensure adequate iodine intake in this population.</description><identifier>EISSN: 1475-2662</identifier><identifier>DOI: 10.1017/S000711452100009X</identifier><language>eng</language><publisher>Cambridge Core</publisher><subject>Dairy products ; Iodine status ; Milk ; Pregnancy</subject><ispartof>British journal of nutrition, 2021-01, p.1-9</ispartof><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><orcidid>0000-0002-8021-4783</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,777,781,27905,27906</link.rule.ids></links><search><creatorcontrib>Ferreira, Pedro</creatorcontrib><creatorcontrib>Pinheiro, Cátia</creatorcontrib><creatorcontrib>Coelho, Cláudia Matta</creatorcontrib><creatorcontrib>Guimarães, Juliana</creatorcontrib><creatorcontrib>Pereira, Gonçalo</creatorcontrib><creatorcontrib>Moreira, Nara Xavier</creatorcontrib><creatorcontrib>Cortez, Alice</creatorcontrib><creatorcontrib>Bracchi, Isabella</creatorcontrib><creatorcontrib>Pestana, Diogo</creatorcontrib><creatorcontrib>Mota, Inês Barreiros</creatorcontrib><creatorcontrib>Prucha, Carmo</creatorcontrib><creatorcontrib>Martins, Cristina</creatorcontrib><creatorcontrib>Ribeiro, Célia Alves</creatorcontrib><creatorcontrib>Pinto, Edgar</creatorcontrib><creatorcontrib>Almeida, Agostinho</creatorcontrib><creatorcontrib>Delerue-Matos, Cristina</creatorcontrib><creatorcontrib>Montenegro, Nuno</creatorcontrib><creatorcontrib>Dias, Cláudia Camila</creatorcontrib><creatorcontrib>Moreira-Rosário, André</creatorcontrib><creatorcontrib>Azevedo, Luís Filipe</creatorcontrib><creatorcontrib>Brantsæter, Anne-Lise</creatorcontrib><creatorcontrib>Ramalho, Carla</creatorcontrib><creatorcontrib>Fernandes, Virgínia Cruz</creatorcontrib><creatorcontrib>Calhau, Conceição</creatorcontrib><creatorcontrib>Leite, João Costa</creatorcontrib><creatorcontrib>Keating, Elisa</creatorcontrib><title>The association of milk and dairy consumption with iodine status in pregnant women in Oporto region</title><title>British journal of nutrition</title><description>The role of milk and dairy products in supplying iodine to pregnant women is unknown in Portugal.
