“…In order to quantify the iodine intake from water, we used a quantitative model, which was previously used in Israel [19]. In this model, iodine from locally retailed bottled drinking water were considered negligible due to low content of iodine (0-10 μg/L [26]).…”

“…In this model, iodine from locally retailed bottled drinking water were considered negligible due to low content of iodine (0-10 μg/L [26]). Filtered water was also excluded due to the high iodine variability of filtered water (in the range of 0-27 μg/L [19]). To model the contribution of drinking-water to daily iodine intake, we used geographic locality specific estimates of water iodide concentration.…”

“…survey (regarding patient demographics, health, a history of thyroid disease, and weight gain during gestation). Correlation between biomarkers and the sIFFQ was used to provide better assessment regarding iodine status, as they are complementary measurements: Tg reflects Iodine intake of weeks to months, and sIFFQ reflects iodine intake during the previous year [19,23]. Spot urinary iodine concentration (UIC) is a common measure in population studies [27].…”

“…The growing prevalence of water desalination globally [17] highlights the importance of data regarding the impact of habitual dietary iodine intake on iodine status [7,17,18]. Such information may be crucial in areas with DIDW reliance, which may diminish iodine intake [7,19]. Israel relies extensively on DIDW [7,20].…”

Background: Iodine is an essential nutrient for human health throughout the life cycle, especially during early stages of intrauterine life and infancy, to ensure adequate neurocognitive development. The growing global reliance on desalinated iodine-diluted water raises the specter of increased iodine deficiency in several regions. The case of Israel may be instructive for exploring the link between iodine status and habitual iodine intake in the setting of extensive national reliance on desalinated water. The aim of this study was to explore the relationship between iodine intake, including iodized salt and iodine-containing supplements intake, and iodine status among pregnant women residing in a sub-district of Israel that is highly reliant on desalinated iodine-diluted water. Methods: A total of 134 consecutive pregnant women were recruited on a voluntary basis from the obstetrics department of the Barzilai University Medical Center during 2018. Blood was drawn from participants to determine levels of serum thyrotropin (TSH), thyroid peroxidase antibodies (TPOAb), thyroglobulin antibodies (TgAb) and thyroglobulin (Tg). An iodine food frequency questionnaire (sIFFQ) was used to assess iodine intake from food, IS and ICS. A questionnaire was used to collect data on demographic and health characteristics. Results: A total of 105 pregnant women without known or reported thyroid disease were included in the study. Elevated Tg values (≥ 13 μg/L), were found among 67% of participants, indicating insufficient iodine status. The estimated iodine intake (median, mean ± SD 189, 187 ± 106 μg/d by sIFFQ) was lower than the levels recommended by the World Health Organization and the Institute of Medicine (250 vs. 220 μg/day respectively). The prevalence of iodized salt intake and iodine containing supplement intake were 4 and 52% (respectively). Values of Tg > 13 μg/L were inversely associated with compliance with World Health Organization and Institute of Medicine recommendations.
