Association of Maternal Iodine Status With Child IQ: A Meta-Analysis of Individual Participant Data

2019

Abstract Context Although the consequences of severe iodine deficiency are beyond doubt, the effects of mild to moderate iodine deficiency in pregnancy on child neurodevelopment are less well established. Objective To study the association between maternal iodine status during pregnancy and child IQ and identify vulnerable time windows of exposure to suboptimal iodine availability. Design Meta-analysis of individual participant data from three prospective population-based birth cohorts: Generation R (Netherlands), INMA (Spain), and ALSPAC (United Kingdom); pregnant women were enrolled between 2002 and 2006, 2003 and 2008, and 1990 and 1992, respectively. Setting General community. Participa…

A cross-sectional survey of urinary iodine status in Latvia

2014

Background and objective: A nationwide survey of schoolchildren was conducted to detect regional differences in urinary iodine excretion in Latvia and to compare the results with data from the newborn thyroid-stimulating hormone (TSH) screening database as well with the results of a similar study performed in Latvia 10 years ago. Materials and methods: We conducted a cross-sectional school-based cluster survey of 915 children aged 9–12 years in 46 randomly selected schools in all regions of Latvia. Urine samples, questionnaires on the consumption of iodized salt and information on socioeconomic status were collected. TSH levels in newborns were also measured. Results: The median creatinine-…

2021 European Thyroid Association Guidelines for the Management of Iodine-Based Contrast Media-Induced Thyroid Dysfunction

2021

Given the fact that a large number of radiological examinations using iodine-based contrast media (ICM) are performed in everyday practice, clinicians should be aware of potential ICM-induced thyroid dysfunction (TD). ICM can induce hyperthyroidism (Hyper) or hypothyroidism (Hypo) due to supraphysiological concentrations of iodine in the contrast solution. The prevalence of ICM-induced TD varies from 1 to 15%. ICM-induced Hyper is predominantly found in regions with iodine deficiency and in patients with underlying nodular goiter or latent Graves’ disease. Patients at risk for ICM-induced Hypo include those with autoimmune thyroiditis, living in areas with sufficient iodine supply. Most cas…

Ensuring Effective Prevention of Iodine Deficiency Disorders

2016

To access publisher's full text version of this article click on the hyperlink at the bottom of the page Programs initiated to prevent iodine deficiency disorders (IDD) may not remain effective due to changes in government policies, commercial factors, and human behavior that may affect the efficacy of IDD prevention programs in unpredictable directions. Monitoring and outcome studies are needed to optimize the effectiveness of IDD prevention. Although the need for monitoring is compelling, the current reality in Europe is less than optimal. Regular and systematic monitoring surveys have only been established in a few countries, and comparability across the studies is hampered by the lack o…

Perspectives on Sustainable Development in the Context of Public Health Issues

2015

Abstract Health is an integral part of sustainable development, a process that can’t be materialized if there is a high prevalence of diseases, a high percentage of those is due to environmental factors. An important component of health is the healthy nutrition, especially of children and pregnant women. Iodine is an essential micronutrient for a good nutrition that covers the physiological needs of the body, iodine deficiency having important consequences for mother and fetus, then for children, especially in the first years of life. The main role of iodine in the body is due to his importance for synthesis of thyroid hormones involved in growth and development of psychic and somatic body,…

Iodine Deficiency in Latvia: Current Status and Need for National Recommendations

2017

Abstract In the absence of a mandatory salt iodisation programme, two nationwide cross-sectional cluster surveys revealed persisting iodine deficiency among Latvian schoolchildren during the spring season and a noteworthy iodine deficiency in pregnant women in Latvia; these deficiencies warrant intervention. The consequences of mild-to-moderate iodine deficiency during pregnancy and lactation can adversely affect foetal brain development. Data from a Latvian population survey revealed the consumption of approximately 100 μg of iodine per day through foods and iodised salt. Therefore, strategies to increase the consumption of iodine-containing products should be implemented, particularly for…

Milk as an Essential Source of Iodine in Latvian Population

2017

Abstract Milk and dairy products are studied as alternative iodine sources, because salt iodisation is controversial due to high salt consumption leading to cardiovascular diseases. However, the iodine concentration in milk markedly varies. This study evaluated the iodine concentration in cow’s milk available in the Latvian market. Iodine and fat concentration was analysed with a spectrophotometer “Varian Cary 50” based ISO 2446:2008 in 20 milk samples. Data from the Central Statistical Bureau and survey among pregnant women were used to analyse milk product consumption and its impact on iodine status. Average iodine concentration in milk samples was 457.6 (179.6) μg/L, winter samples had a…

Joda deficīts grūtniecēm teritoriālā griezumā un tā ietekme uz intelektuālo attīstību bērniem Latvijā

2015

Latvijā ilgstoši pastāv joda deficīts, kas ir bīstams sabiedrības veselībai un intelektuālajai attīstībai. Pat neliels joda deficīts grūtniecības periodā izraisa bērna IQ pazemināšanos, līdz ar to vēlāk arī iespējamu valsts IKP per capita samazināšanos. Uzdevumi: izvērtēt joda pietiekamību Latvijas grūtniecēm reģionālā griezumā, sakarības ar saistītiem faktoriem, kā arī censties identificēt sakarību starp joda koncentrāciju urīnā (JU) skolēniem un atzīmēm valsts eksāmenos. Visos Latvijas reģionos grūtniecēm konstatēts joda deficīts (mediānā JU 64.5-89.9 µg/g Cr). Starp grūtnieču JU un jodu saturošu vitamīnu lietošanu statistiski ticama sakarība atrasta tikai Zemgalē, bet ar jodsāls lietošan…

Maintenance of iodine intake

2013

Dietary iodine status is routinely assessed by measuring urinary iodine excretion (UI). In most European countries iodine intake is maintained at WHO recommended levels by iodisation of table salt [1]. Exceptions to this practice include Ireland and the UK where only 5% (approximately) of table salt sold is iodine supplemented. However despite the finding of relatively low median UI values in study populations in both Ireland and the UK [2-4] there is little evidence of an increased prevalence of hypothyroidism, overt or subclinical, of non autoimmune pathogenesis [5-8]. In this communication studies on iodine status in the Irish population over the years 1988-2007 are reviewed, as are inve…
