Iodine deficiency continues to plague Pakistan

(Michael Zimmermann )
Pakistan is the 6th most populous country in the world with over 180 million people, and 42% of the population is below 14 years old. Pakistan is historically iodine defici-ent; one cause is the heavy monsoon rains that cause regular flooding and erosion that leaches iodine from soils. The worst floods in the country’s history occurred in 2010 and 2011, further depleting already iodine-poor soils. The current median urinary iodine concentration (UIC) in school age children is only 75 µg/L, with 64% of children having insufficient iodine intake (1). UNICEF estimates that only 17% of Pakistani households are consuming iodized salt (2) ...

The U.S. CDC’s ‘Ensuring the Quality of Urinary Iodine Procedures (EQUIP) Program’ is 10 years old

(Amir A. Makhmudov, Kathleen L. Caldwell)
Over the past decade, the EQUIP program has become the center of global urinary iodine laboratory quality assurance ...

Iodization of food industry salt is vital to control IDD in Belarus

(V. Kachan, T. Mokhort, N. Kolomiets, V. Filonov, S. Petrenko, Z. Zabarovskaya, N. Gusina, G. Gerasim)
For more than 10 years, the Republic of Belarus has aggressively pursued the goal of IDD elimination through universal salt iodization (USI). In June 2000, at the National Conference on IDD Elimination, the “State Strategy for IDD Elimination through USI in Republic of Belarus” was adopted. In 2001, the Government of Belarus adopted a resolution “On IDD Prevention” that introduced mandatory use of iodized salt in the food industry and public catering, and required obligatory use of iodized salt in the salt retail trade. In 2008, provisions of this government decree were included as amendments to Food Safety Law ...

The Mexican USI program provides ample dietary iodine to low-income pregnant women

(García-Solís P, Solís-S JC, García-Gaytán AC)
It has been shown that in some countries, although iodine intake is sufficient in school-age children, there is iodine defi-ciency in pregnant women. This finding justifies the need for a continuous moni-toring of iodine nutrition in these two vulnerable populations. In Mexico, there are no recent data regarding UIC in child-ren and pregnant women, but there is an effective USI program. In 2009, 81% of all marketed salt in Mexico contained an ade-quate iodine concentration (20–40 ppm), and 94% of samples contained 15 ppm of iodine (1). However, the quality of the salt is not homogenous throughout the country. There are places where only 25% of the salt samples have 15 ppm of iodine (2). This could contribute to insufficient iodine intake, and to a heterogeneous iodine nutrition status ...

High iodine intakes in school children in Eastern Nepal

(Prem Raj Shakya, Basanta Gelal and Nirmal Baral)
Eastern Nepal has three ecological regions (mountain, hill and terai) (Figure 1). A previous national IDD survey in 2007 (1) reported the percentage of children having urinary iodine excretion (UIE) <100 µg/L was 26.1% in the mountain region, 18.9% in the hills and 9.1% in the terai region of Eastern Nepal. The fundamental problem of Nepal is the geochemical structure rises steeply from a few meters above the sea level in the southern plain to the high Himalayas. This is responsible for the leaching of iodine from the soil. People living in mountainous and hilly regions do not have easy access to adequately iodized salt because of long transportation time from the point of production, less coverage of these areas by roads, easy avai-lability of crystal salt at the lowest price and poor storage condition in households ...

Careful quantitative monitoring of salt iodine levels in the Philippines is critical to ensure adequate iodine intake

(Leah Perlas and Mario Capanzana )
In the Philippines, in response to an increase in goiter rates from 3.5% in 1987 to 6.7% in 1993 among Filipinos 7 years and older, an Act for Salt Iodization Nationwide (ASIN Law) was passed in 1995. Since the implementation of the ASIN LAW, there has been an increasing national awareness of the importance of iodized salt among Filipinos, from 67.3% in 1998 to 79.5% in 2003, 83.4% in 2005 and 78.5% in 2008 (Figure 1) (1). Based on household salt testing positive to rapid test kits (RTK), there was an increase in use of iodized salt from 24.8% in 1998 to 81.1% in 2008. Surprisingly, in 2008, among those who were aware of the importance of iodized salt, only 53.3% claimed to be users of iodized salt. The primary sources of information on iodized salt were television and health personnel, based on the 2008 National Nutrition Survey (NNS) conducted by FNRI-DOST ...
