Context: Iodine deficiency is the leading cause of preventable neurodevelopmental delay in children worldwide and a possible public health concern in Haiti.
Objective: To determine the prevalence of iodine deficiency in Haitian young children and its influence by environmental factors.
Design: Cross-sectional study, March through June 2015.
Setting: Community churches in 3 geographical regions in Haiti.
Participants: 299 healthy Haitian children aged 9 months to 6 years; one-third each enrolled in a coastal, mountainous, and urban region.
Main Outcome Measures: Urinary iodide, serum thyrotropin (TSH), goiter assessment, and urinary perchlorate and thiocyanate.
Results: Mean age was 3.3±1.6 years, with 51% female, median family income USD 30/week, and 16% malnutrition. Median urinary iodide levels were normal in coastal (145 μg/L, interquartile range [IQR] 97 to 241) and urban regions (187 μg/L, IQR 92 to 316), but revealed mild iodine deficiency in a mountainous region (89 μg/L, IQR 56 to 129), P < 0.0001. Grade 1 goiters were palpated in 2 children, but TSH values were normal. Urinary thiocyanate and perchlorate concentrations were not elevated. Predictors of higher urinary iodide included higher urinary thiocyanate and perchlorate, breastfeeding, and not living in a mountainous region.
Conclusions: Areas of mild iodine deficiency persist in Haiti's mountainous regions. Exposure to two well-understood environmental thyroid function disruptors is limited.

Context: Congenital hypothyroidism (CH) is one of the most common preventable causes of intellectual disability, and can be diagnosed in the early period through neonatal screening programs.
Objective: The purpose of this study was to determine the prevalence of CH and recall rates in the province of Adıyaman.
Design: This retrospective study evaluated the data of newborn screening program in Adıyaman province between January 2015 and December 2020.

Objectives: The relationship between iodine status and gestational diabetes mellitus (GDM) is inconclusive. This study aimed to explore the trajectories of urinary iodine concentrations (UIC) in pregnant women before GDM diagnosis and to assess the associations between maternal UIC trajectories and the risk of developing GDM.
Methods: A prospective cohort study was conducted in China.

To analyze the iodine nutrition status and its related factors among adults aged 18 years and above in Zhejiang Province in 2022. A multistage stratified sampling method was used to select 4 320 adults aged 18 years and above from 16 on-site survey sites in Zhejiang Province for the study. A questionnaire was used to investigate the general demographic information and personal dietary characteristics of the study participants.

In this study, we introduce a highly effective non-metallic iodine single-atom catalyst (SAC), referred to as I-NC, which is strategically confined within a nitrogen-doped carbon (NC) scaffold. This configuration features a distinctive C-I coordination that optimizes the electronic structure of the nitrogen-adjacent carbon sites. As a result, this arrangement enhances electron transfer from peroxymonosulfate (PMS) to the active sites, particularly the electron-deficient carbon.

Recent studies on iodine biofortification of potato have documented various iodine contents in tubers: from very low to such covering the Recommended Daily Allowance (RDA-I). The aim of the work was to evaluate the efficiency of iodine biofortification of potato using six iodoquinolines applied in two doses, with KIO as a reference compound. The mineral status of potato plants and the nutritional and health-promoting value of tubers were also studied.
