Filter by:The overall aim of the study is to monitor the effects of the increased iodine fortification level implemented in 2019 on iodine intake from the diet (incl. dietary supplements) and the excretion of iodine in urine in children aged 2-10 years.
The overarching objective of this two-phase project is to assess the effects of fortifying iodized salt with folic acid on improving women's folate status. Folate insufficiency is the primary risk factor for neural tube defects (NTDs), which are highly prevalent in Ethiopia. The purposes of Phase 2 of the project, described herein, are to complete a community-based, randomized, dose-response intervention trial of edible salt fortified with just iodine or iodine and one of two levels of folic acid among non-pregnant women of reproductive age (WRA), We will assess the effects of the intervention on women's discretionary salt intakes, markers of folate and iodine status, and incidence of any adverse events.
Mild-to-moderate iodine deficiency remains a problem in many parts of the world, including Norway. Of particular concern are fertile, pregnant, and lactating women. The Norwegian Dairy Council developed a digital iodine-specific food frequency questionnaire (I-FFQ) for the assessment of iodine intake levels, but it has yet to be validated. The main objective was thus to investigate the relative validity of the I-FFQ by comparing estimates of iodine intake obtained from the I-FFQ against a single 24-hour recall (24HR) and urinary iodine concentration (UIC) in fertile women.
In describing the iodine status involving health conditions of the minority groups, this observational study aims to learn about the iodine status of the Indigenous Peoples (Karen) in a subdistrict in western Thailand. The Participants will be collected their urine to determine urinary iodine concentrations At the same time, their household salt will be also collected to determine iodine content.
The goal of this clinical trial is to learn about the effects of iodine-containing multiple micronutrient supplements provided to breastfeeding mothers who live in settings with mild iodine deficiency. The main questions it aims to answer are: 1. What are the effects of iodine-containing multiple micronutrient supplements provided to breastfeeding mothers on infant development, as measured by electroencephalography/visual evoked potentials? 2. What are the effects of iodine-containing multiple micronutrient supplements on breast milk concentrations of iodine, and infant iodine and thyroid status? 3. How do iodine and iron interact with each other to affect thyroid function in the mother during pregnancy and lactation? Participants will be randomized to receive a daily iodine-containing multiple micronutrient tablet for 6 months after birth, or routine care. Mothers will provide a breast milk sample and drop of blood at 1 and 6 months. Infants will provide a urine sample and drop of blood at 1 and 6 months of age, and a developmental assessment including an Electroencephalogram at 6 months of age. Researchers will compare the groups that received the iodine-containing micronutrient supplement with the group that received routine care and see if there were any benefits on infant development and iodine and thyroid status in the mother and baby.
To determine and explore the iodized salt concentration provided in the local community, especially in the Phu Kut district whether it meets the standard or not. This district is located in a mountainous area which means that the local community confronts with geographical access due to the limited transportation and road condition, in addition, it is quite far from downtown approximately 26 kilometers and it is difficult to access the iodized salt consumption. On the other hand, since 2013, the Lao People's Democratic Republic has implemented the iodized survey of urine among the primary students, this time could be the chance to compare based on the previous data, which will be an important source of the data for certifying the quality of iodized salt available in the local community that could be one cause of lacking iodized salt intake. Furthermore, the investigators could conduct the survey and monitor the current action plan related to iodized consumption in Laos as well, in order to eradicate diseases concerning with lacking iodized salt intake. Objectives 1. To investigate the nutritional status of school-aged children (SAC) living in Phu Kut City, Xieng Khouang province. 2. To investigate the iodine status and iodized salt use of school-aged children (SAC) living in Phu Kut City, Xieng Khouang province.
The overarching objective of this two-phase project is to assess the effects of fortifying iodized salt with folic acid on improving women's folate status and thereby reduce the risk of neural tube defects (NTDs), which are highly prevalent in Ethiopia. The project will be conducted in two phases. The purpose of Phase 1, described herein, is to complete formative research in preparation for a community-based, randomized trial, which will be carried out in Phase 2. The objectives of Phase 1 are to: 1) assess the hematological condition and nutritional status with respect to folate, iodine, and other micronutrients among non-pregnant women of reproductive age (WRA) in the study communities, and 2) measure discretionary salt and dietary folate intakes of the women and their households.
Seaweed is becoming increasingly popular in the Western part of the world, especially sushi wrapped in nori and seaweed salad, also called wakame. There are limited data on the iodine content of different seaweed products in the Norwegian Food composition table. Furthermore, there is limited available research regarding in vivo bioavailability of iodine from seaweeds. The objective of this study is to assess whether iodine from a sushi meal (with nori, Porphyra spp), and a wakame salad (Undaria pinnatifida) has similar bioavailability as a potassium iodide reference supplement of similar iodine content.
The goal of this observational study is to compare urine iodine levels of participants with/without periodontitis. The main question it aims to answer is there a relationship between iodine levels of urine and periodontitis. Participants will give urine samples without any intervention.
PICk study is a mHealth intervention in women trying to conceive and women up to 14 weeks pregnant, aiming to guide food choices, to achieve the recommended iodine intake through diet.
