A dose-response crossover iodine balance study to determine iodine requirements in early infancy
Dold, Susanne; Baumgartner, Jeannine; Zimmermann, Michael B.; Davaz, Tabea; Galetti, Valeria (American Society for Nutrition, 2016)Background: Optimal iodine intake during infancy is critical for brain development, but no estimated average requirement (EAR) is available for this age group. Objective: We measured daily iodine intake, excretion, and ... -
Amyloid fibril systems reduce, stabilize and deliver bioavailable nanosized iron
Shen, Yi; Baumgartner, Jeannine; Posavec, Lidija; Bolisetty, Sreenath; Hilty, Florentine M. (Nature, 2017)Iron-deficiency anaemia (IDA) is a major global public health problem1. A sustainable and cost-effective strategy to reduce IDA is iron fortification of foods2, but the most bioavailable fortificants cause adverse organoleptic ... -
Antenatal multiple micronutrient supplementation: benefits beyond iron-folic acid alone
Baumgartner, Jeannine (Elsevier, 2017) -
Breast-milk iodine concentrations, iodine status, and thyroid function of breastfed infants aged 2-4 months and their mothers residing in a South African township
Osei, Jennifer; Smuts, Cornelius M.; Baumgartner, Jeannine; Andersson, Maria; Van der Reijden, Olivia; Dold, Susanne (Galenos Yayincilik, 2016)Objective: Lactating women and their infants are susceptible to iodine deficiency and iodine excess. In South Africa, no data exist on the iodine status and thyroid function of these vulnerable groups. Methods: In a ... -
Food or nutrient pattern assessment using the principal component analysis applied to food questionnaires. Pitfalls, tips and tricks
Ricci, Cristian; Baumgartner, Jeannine; Wentzel-Viljoen, Edelweiss; Smuts, Cornelius M. (Taylor & Francis, 2019)We considered the Blom’s transformation, a statistical method aimed to normalise and standardise food intakes before principal component analysis. A simulation study was performed to evaluate the eigenvalue distribution ... -
Interventions to prevent iron deficiency during the first 1000 days in low-income and middle-income countries: recent advances and challenges
Lewies, Angélique; Zandberg, Lizelle; Baumgartner, Jeannine (Wolters Kluwer, 2019)Purpose of review Iron deficiency remains highly prevalent in women and young children in low-income and middle-income countries. To prevent the potentially life-long consequences of iron deficiency when occurring during ... -
Iron and a mixture of DHA and EPA supplementation, alone and in combination, affect bioactive lipid signalling and morbidity of iron deficient South African school children in a two-by-two randomised controlled trial
Malan, L.; Baumgartner, J.; Zandberg, L.; Smuts, C.M.; Calder, P. (Elsevier Sci Ltd, 2016)We recently reported that iron supplementation increased respiratory morbidity in iron deficient South African children. This increase, however, was attenuated when iron was provided in combination with a mixture of DHA/EPA. ... -
Low immune cell ARA and high plasma 12-HETE and 17-HDHA in iron-deficient South African school children with allergy
Malan, L.; Baumgartner, J.; Smuts, C.M.; Calder, P. (Elsevier, 2016)Allergy has been associated with altered fatty acid and inflammatory status. In this cross-sectional study of 321 rural iron deficient (ID) South African children (aged 6–11 years), a subsample (n=111) of children with ... -
Maternal iron-deficiency is associated with premature birth and higher birth weight despite routine antenatal iron supplementation in an urban South African setting: the NuPED prospective study
Symington, Elizabeth A.; Baumgartner, Jeannine; Malan, Linda; Ricci, Cristian; Zandberg, Lizelle; Smuts, Cornelius M. (PLoS, 2019)Background Recent studies are suggesting a U-shaped relationship between antenatal iron exposure and birth outcomes. Little is known about the iron status and associated birth outcomes of pregnant women in South Africa. ... -
Optimization of a new mass spectrometry method for measurement of breast milk iodine concentrations and an assessment of the effect of analytic method and timing of within: feed sample collection on breast milk iodine concentrations
Dold, Susanne; Baumgartner, Jeannine; Osei, Jennifer; Zeder, Christophe; Krzystek, Adam (Mary Ann Liebert, Inc, 2016)Background: Breast milk iodine concentration (BMIC) may be an indicator of iodine status during lactation, but there are few data comparing different analytical methods or timing of sampling. The aims of this study were: ... -
Type of dietary fat intakes in relation to all-cause and cause-specific mortality in US adults: an iso-energetic substitution analysis from the American National Health and Nutrition Examination Survey linked to the US mortality registry
Ricci, Cristian; Baumgartner, Jeannine; Zec, Manja; Kruger, Herculina Salome; Smuts, Cornelius M. (Cambridge Univ Press, 2018)Accumulating evidence indicates that saturated fat intake is related to mortality risk increase, whereas unsaturated fat intake is associated with reduced mortality risk. The aim of the present study was to estimate the ...
