Measurement of iodine status is one of those things that can seem simple until you get into the details. The recent paper by Andersen et al. in the British Journal of Nutrition provides some important new insights into, and an opportunity to reflect on, some fundamental considerations. Iodine is an essential nutrient through its role in thyroid hormones, and must be obtained from the diet in su...
Introduction: Biosynthesis of thyroid hormone and consequently the requirement for iodine have been established to increase during gestation mainly due to increased iodine demand by the fetus. Therefore, diminished iodine intake by the mother during early pregnancy eventually leads to the development of iodine deficiency disorders(IDDS) in the offspring. The present study aimed to explore...
OBJECTIVE To know extent of iodine deficiency (ID), role of thyroid enlargement (goiter) as marker of ID and current status of iodized salt intake in pregnant women of Lahore. METHODS A cross sectional study was carried out at Institute of Chemistry, University of the Punjab, during March 2002 to September 2005. Pregnant women (n = 254) during first trimester attending antenatal clinic partic...
A multi community environment-and-health study among six of the nine communities of Eeyou Istchee in northern Quebec, Canada provided greater insight into iodine intake levels among these Cree First Nation communities. Using data from this large population-based study, descriptive statistics of measured urinary iodine concentrations (UICs) and iodine-creatinine ratios (stratified by age, sex, c...
Objective: A significant negative association between serum thyroxine and urine perchlorate levels had been reported from NHANES 2001-2002 by Blount et al. (2006) for women age 12-85 with low iodine nutrition expressed as urine iodine (UI) less than 100 ug/l. We have reanalyzed the data using creatinine-adjusted urine iodine (UICr) as the measure of iodine nutrition and focused on women of chil...
OBJECTIVES Median urinary iodine concentration (UIC) is the recommended method to evaluate iodine status in pregnancy, but several factors may challenge the interpretation of the results. We evaluated UIC in pregnant women according to (1) sampling in the hospital versus at home, (2) time of the most recent iodine supplement intake prior to sampling, and (3) members of their household. STUDY ...
OBJECTIVE An increasing incidence of hyperthyroidism has been observed when iodine supplementation has been introduced to an iodine-deficient population. Moreover, the influence of chronic more than adequate or excessive iodine intake on the epidemiological features of hyperthyroidism has not been widely and thoroughly described. To investigate the influences of different iodine intake levels o...
BACKGROUND AND OBJECTIVE: Congenital hypothyroidism due to iodine deficiency is the most common cause of preventable mental retardation in the world. The lowest level of iodine deficiency during pregnancy could result in disorders such as miscarriage, premature delivery, intrauterine fetal death, low birth IQ, mental retardation, hearing difficulty and speech impediments. This study aimed to ev...
