BACKGROUND Salt iodization is the main strategy for reducing iodine deficiency disorders worldwide. Characteristics of families not using iodized salt need to be known to expand coverage. OBJECTIVE The objective was to determine whether families who do not use iodized salt have a higher prevalence of child malnutrition and mortality and to identify factors associated with not using iodized sa...

BACKGROUND & OBJECTIVE Universal salt iodization (USI) was implemented in all counties of China in 1995. This study was undertaken to assess the status of iodine deficiency disorders control and prevention after 10 years of implementation of USI in a severe iodine deficiency region in China. METHODS Thirty primary school were selected in Gansu province utilizing cluster sampling methodology f...

A survey was conducted to monitor the current status of iodine deficiency disorders in children aged 6-12 years and women aged 15-44 years in Bangladesh as measured by goitre prevalence and urinary iodine excretion. Conducted between September 2004 and March 2005, the survey followed a stratified multistage cluster sampling design to provide nationally representative data, with self-weighted ru...

Objective: Universal salt iodization is an effective strategy to optimize population-level iodine. At the same time as salt-lowering initiatives are encouraged globally, there is concern about compromised iodine intakes. This study investigated whether salt intakes at recommended levels resulted in a suboptimal iodine status in a country where salt is the vehicle for iodine fortification. Metho...

OBJECTIVE Iodization of salt was introduced in Denmark in 1998 because of mild-to-moderate iodine deficiency (ID). The aim of this study was to analyze the utilization rate of surgery and radioiodine therapy for benign thyroid disorders before and after the introduction of iodization, and to study a possible association between the changes and the raised iodine intake. DESIGN A nationwide reg...

OBJECTIVE To establish a laboratory iodization quality assurance system to support small-scale salt production facilities in India and to assess the level of agreement for the internal quality assurance (IQA) and external quality assurance (EQA) protocols. DESIGN Operational research. The IQA and EQA programme was established in the year 2008. Agreement between field laboratories and the refe...

OBJECTIVE To study (i) the current prevalence of iodine-deficiency disorders among schoolchildren in south-western Saudi Arabia after universal salt iodization and (ii) the iodine content of table salts and water. DESIGN Cross-sectional study on a stratified proportional allocation sample of children. Thyroid gland enlargement was assessed clinically and by ultrasound scanning. Urine, table s...

Though the consequences of nutritional iodine deficiency have been known for a long time, in Cambodia its elimination has only become a priority in the last 18 years. The Royal Government of Cambodia initiated the National Sub-Committee for Control of Iodine Deficiency Disorders in 1996 to fight this problem. Using three different surveys providing information across all provinces, we examined ...

OBJECTIVE Although goitre and cretinism were brought under control in Kyrgyzstan during the 1960s by centrally directed iodized salt supplies, iodine-deficiency disorders (IDD) had made a comeback when the USSR broke up in 1991. Upon independence, Kyrgyzstan started developing its own salt processing industry and by 2001 the Government enacted a law on IDD elimination, mandating universal salt ...
