A Bit of Salt, A Trace of Life: Long-Run Impacts of Salt Iodization in China

This work compares the human capital development of cohorts born before and after the salt iodization in areas with varying pre-intervention iodine deficiency prevalence (goiter rates), and sees a substantial reduction of the gender ability gap.

Cognitive Consequences of Iodine Deficiency in Adolescence: Evidence from Salt Iodization in Denmark

It is found that salt iodization increases the GPA of students by 6-9 percent of a standard deviation, and combines administrative records on high school grades over a thirty-year period with geographic variation in initial iodine deficiency.

This paper is the first to provide evidence of a direct causal impact of iodine fortification in early life on cognitive skills in childhood. I apply a differences-indifferences strategy using…

A Bit of Salt, a Trace of Life: Gender Norms and the Impact of a Salt Iodization Program on Human Capital Formation of School Aged Children

This paper evaluates the effect of a national salt iodization program on the cognition of school-aged children in China. We focus on the role of gender preferences. Linking pre-eradication iodine…

Infant Health and Later-Life Labor Market Outcomes

It is found that mitigation of pneumonia infection in infancy increased labor income in late adulthood by 2.8–5.1 percent and the beneficial effects are strong for health, measured by length of stay in hospital, but weaker for years of schooling.

The Cognitive Effects of Micronutrient Deficiency: Evidence from Salt Iodization in the United States

It is found that for the one quarter of the population most deficient in iodine this intervention raised IQ by approximately one standard deviation, which can explain roughly one decade's worth of the upward trend in IQ in the US (the Flynn Effect).

The effects of the generalized use of iodized salt on occupational patterns in Switzerland

Examination of the impact of salt iodization in Switzerland in the 1920s and 1930s finds that cohorts born in previously highly-deficient areas after the introduction of iodized salt self-selected into higher-paying occupations, whereas they opted out of physical-labor-intensive occupations.

The eradication of iodine deficiency in previously deficient areas increased the schooling of the population significantly, and the effects are larger for females than for males, which is consistent with medical evidence showing that women are more likely to be affected by iodine deficiency disorders than men.

A controlled trial of iodinated oil for the prevention of endemic cretinism: a long-term follow-up.

The results showed that if the iodine supplement was given before conception the nervous form of endemic cretinism was prevented and justifies the use of the term iodine deficiency disorder to cover the polymorphic nature of the abnormalities attributable to iodine deficiency.

Research on iodine deficiency and goiter in the 19th and early 20th centuries.

Pioneering studies by Swiss and American physicians demonstrated the efficacy of iodine prophylaxis in the prevention of goiter and cretinism and today, control of the iodine deficiency disorders is an integral part of most national nutrition strategies.
