A Review of Iodine Nutrition Situation in Bhutan; Historical Milestones: OAJBS Publishers
A Review of Iodine Nutrition Situation in Bhutan; Historical Milestones by Hari Prasad Pokhrel* in Open Access Journal of Biomedical Science (OAJBS)
Iodine
is a micronutrient required for production of thyroid hormones which plays a
critical role in metabolism. Iodine deficiency can lead to many severe effects
throughout the human life cycle and is collectively termed as iodine deficiency
disorders. Salt fortification is an effective intervention to improve iodine
nutrition in the population. In Bhutan, iodine deficiency disorders (IDD) were
universally present with the first nationwide survey conducted in 1983,
reporting a total goiter rate of 64.5%. This lead to establishment of
‘Nutrition Section’ in the Directorate of Health and the Iodine Deficiency
Disorders Control Program (IDDCP) in planning commission in 1985. Several
public health interventions were undertaken to address this public health
burden; salt iodization and distribution, iodized oil injections, establishment
of the Bhutan Salt Enterprise in Phuntsholing and program evaluation. Since
then, many assessments were conducted to evaluate the program all of which
reported significant improvements. In 2003 an external monitoring team
confirmed that Bhutan was the first country in WHO SEARO to have eliminated IDD
as a public health problem. An assessment conducted in 2010 reported that
Bhutan was sustaining the IDD elimination status achieved in 2003. Constant
program improvements and investments are required to sustain this achievement.
Iodine content of various salt brands needs to be analysed from time to time to
regulate import control and surveys must be conducted periodically for program
evaluation.
