Summary
This comprehensive narrative review by Hatch-McChesney and Lieberman examines iodine deficiency as a re-emerging global public health issue, despite decades of salt iodisation programmes. The authors synthesise evidence on the biochemical roles of iodine, populations at particular risk, and the neurological and metabolic consequences of inadequate intake. The paper likely concludes that sustained attention to iodine status and dietary adequacy remains essential, particularly in vulnerable groups including pregnant women and those in regions with iodine-poor soils.
UK applicability
The United Kingdom has adequate iodine status in the general population owing to historical salt iodisation and dairy farming practices, though some UK subpopulations (particularly pregnant and lactating women, and those consuming restricted diets) may be at risk. The review's findings on vulnerable groups are applicable to UK nutrition policy and clinical practice.
Key measures
Iodine intake; thyroid-stimulating hormone (TSH); thyroid volume; cognitive outcomes; prevalence of goitre and cretinism; urinary iodine concentrations
Outcomes reported
The paper reviews the prevalence, causes, consequences, and management of iodine deficiency disorder globally, with particular attention to its re-emergence as a public health concern. It examines iodine's role in thyroid function and cognitive development across populations.
