Iodine deficiency is the leading cause of preventable mental retardation in the world today. Iodine deficiency was common in the developed world until the introduction of iodized salt in the 1920’s. The incidence of iodine deficiency is connected to low iodine levels in the soil and water. We examine the impact of salt iodization in the US by taking advantage of this natural geographic variatio...

OBJECTIVE To determine the iodine concentration in household salt, the coverage of adequately iodized salt, the use of non-iodized agricultural and producers' salt, and the usefulness of salt as a carrier of iodine, and to relate these observations to socioeconomic status in South Africa. METHOD The iodometric titration method was used to analyse 2043 household salt samples collected using a ...

OBJECTIVES This study was conducted to assess household coverage with iodized salt in Saudi Arabia, and to determine adequacy of salt iodization. METHODS A school-based cross-sectional study using WHO 30-cluster survey methodology. RESULTS Analysis of 4242 salt samples using qualitative rapid test kit (RTK) revealed that 68.7% (95% CI 67.3-70.1%) were iodized with significant regional diffe...

Perspectives High dietary salt is considered to cause about 30% of cases of hypertension. 1 Globally, approximately one quarter of the adult population has hyperten-sion, a leading risk factor for premature death. By 2025 it will affect 1.56 billion adults in the world and more than 90% of those aged 80 years or more will develop hypertension. High salt intake is also linked to other important ...

Food fortification is a cost-effective approach to prevent and control of micronutrient deficiencies in India. A cross-sectional survey of children 0-35 months of age residing in the catchment areas of anganwadi centers in the state of Telangana was conducted to assess the coverage of adequately iodized salt and the potential for rice fortification. Salt samples were collected and tested for io...

Few data on iodine status in Somalia are available, but it is assumed that deficiency is a public health problem due to the limited access to iodized salt. We aimed to describe the iodine status of the population of Somalia and to investigate possible determinants of iodine status. A national 2-stage, stratified household cluster survey was conducted in 2009 in the Northwest, Northeast, and Sou...
