The Argentinian mother-and-child contaminant study: a cross-sectional study among delivering women in the cities of Ushuaia and Salta
Økland, Inger; Odland, Jon Øyvind; Matiocevich, Silvinia; Alvarez, Marisa Viviana; Aarsland, Torbjørn; Nieboer, Evert; Hansen, Solrunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-28)Several ongoing international multidisciplinary projects have examined linkages between environmental chemicals and health. In contrast to Arctic regions, information for the Southern Hemisphere is scarce. Because of the inherent practice of pesticide utilisation and mismanagement, food security is potentially threatened. The most vulnerable period in human life occurs during pregnancy and early ... -
Assessing the relationship between perfluoroalkyl substances, thyroid hormones and binding proteins in pregnant women; a longitudinal mixed effects approach
Berg, Vivian; Nøst, Therese Haugdahl; Hansen, Solrunn; Elverland, Astrid; Veyhec, Anna-Sofía; Jorde, Rolf; Odland, Jon Øyvind; Sandanger, Torkjel M (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04)<p>The mechanisms involved in thyroid homeostasis are complex, and perfluoroalkyl substances (PFASs) have been indicated to interfere at several levels in this endocrine system. Disruption of the maternal thyroid homeostasis during early pregnancy is of particular concern, where subclinical changes in maternal thyroid hormones (THs) may affect embryonic and foetal development.</p> <p>The present ... -
Maternal Blood Levels of Toxic and Essential Elements and Birth Outcomes in Argentina: The EMASAR Study
Xu, Shanshan; Hansen, Solrunn; Sripada, Kam; Aarsland, Torbjørn; Horvat, Milena; Mazej, Darja; Álvarez, Marisa V.; Odland, Jon Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-18)Pregnant women’s levels of toxic and essential minerals have been linked to birth outcomes yet have not been adequately investigated in South America. In Argentina, n = 696 maternal whole blood samples from Ushuaia (n = 198) and Salta (n = 498) were collected in 2011–2012 among singleton women at 36 ± 12 h postpartum and analyzed for blood concentrations of arsenic (As), cadmium (Cd), mercury (Hg), ... -
Maternal concentrations, predictors and change in profiles of organochlorines, toxic and essential elements during pregnancy and postpartum : the Vietnamese mother-and-child study and the Northern Norwegian mother-and-child study
Hansen, Solrunn (Doctoral thesis; Doktorgradsavhandling, 2011)Persistent toxic substances like organochlorines (OCs) and certain toxic metals have been or are extensively used, and can be globally distributed by long-range transport. The fetus and growing child are exposed via the placenta and breast milk and are vulnerable to their negative health effects. Concentrations measured in maternal blood or breast milk are thus potential indicators of risk for ... -

Midwives and public health nurses' knowledge and clinical practice in securing sufficient iodine status in relation to pregnancy. A cross-sectional study
Johnsen, Maren; Braaten, Tonje Bjørndal; Skeie, Guri; Laholt, Hilde; Hansen, Solrunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-25)Aim - To investigate midwives' (MWs) and public health nurses' (PHNs) clinical practice and knowledge related to nutrition, with a particular focus on iodine in northern parts of Norway. Maternal iodine status prior to and during pregnancy, and the lactating period, is crucial for brain development and growth of the foetus and infant, from conception up until the first two years of life. In Norway, ... -
Monitoring temporal trends of dioxins, organochlorine pesticides and chlorinated paraffins in pooled serum samples collected from Northern Norwegian women: The MISA cohort study
Xu, Shanshan; Hansen, Solrunn; Rautio, Arja; Riitta-Järvelin, Marjo; Abass, Khaled; Rysä, Jaana; Palaniswamy, Saranya; Huber, Sandra; Grimalt, Joan O.; Dumas, Pierre; Odland, Jon Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-30)The ubiquitous presence of legacy and emerging persistent organic pollutants (POPs) in the environmental matrices poses a potential hazard to the humans and creating public health concerns. The present study aimed to evaluate dioxins, dioxin-like polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) and chlorinated paraffins (CPs) concentrations in serum of women (postpartum, pregnant ... -

Overview of ongoing cohort and dietary studies in the Arctic
Weihe, Pál; Bjerregaard, Peter; Bonefeld-Jørgensen, Eva; Dudarev, Alexey; Halling, Jónrit; Hansen, Solrunn; Muckle, Gina; Nøst, Therese Haugdahl; Odland, Jon Øyvind; Petersen, Maria Skaalum; Rautio, Arja; Veyhe, Anna Sofia; Wennberg, Maria; Bergdahl, Ingvar (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-23)This article gives an overview of the ongoing cohort and dietary studies underlying the assessment of population health in the Arctic. The emphasis here is on a description of the material, methods and results or preliminary results for each study. Detailed exposure information is available in an article in this journal, whereas another paper describes the effects associated with contaminant ... -
Persistent Organic Pollutants and the Association with Maternal and Infant Thyroid Homeostasis: A Multipollutant Assessment
Berg, Vivian; Nøst, Therese Haugdahl; Pettersen, Rolf Dagfinn; Hansen, Solrunn; Veyhe, Anna Sofia; Jorde, Rolf; Odland, Jon Øyvind; Sandanger, Torkjel M (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01)Background:<br>Disruption of thyroid homeostasis has been indicated in human studies targeting effects of persistent organic pollutants (POPs). Influence on the maternal thyroid system by POPs is of special interest during pregnancy because such effects could impair infant thyroid homeostasis.<br> Objectives:<br>We investigated the association between POPs and thyroid-stimulating hormone (TSH) ... -
