An example of a goiter in a subject

After years of assessing UIC, IDD, TSH, and TV it is
unknown as to why goiter is still endemic in all regions of
Ethiopia and why USI programs are not successful 1,2,4,7,8.
Study findings indicate considerable differences in goiter
prevalence among geographical regions of Ethiopia1,2,4.
http://en.wikipedia.org/wiki/Goitre
However, there are no know studies that explore
geographical location and population density of regions,
with association to goiter prevalence for Ethiopia as a
whole.
If goiter prevalence is
association to population
density, then population
density maps could be
utilized to focus USI and
education programs in
those regions most in
need.

Criteria9
For patients who presented with goiter; age, gender,
place of residence, and goiter grade were recorded.
Physical Examination9
(pregnancy &

medications)
(vitals & thyroid status)
Results indicate that goiter prevalence might be
negatively correlated to population density.

In Ethiopia, IDD has been recognized as a major public
health problem for the last 60 years9.
Despite the introduction of Universal Salt Iodization (USI)
programs in 1990, Ethiopia is still the top iodine deficient
country in the world based on a national UIC <100 ug/L8.
Girma et al (2014) determined that in Northwest Ethiopia
the total goiter prevalence was 39.5%, with UIC ranging
from 20.54 - 62.3 ug/L. Further more, only 15 – 20% of
households in this region had and used iodized salt4.
In Southeastern Ethiopia, goiter
prevalence was determined to be
27.4 - 42.0%1.
In Southwestern Ethiopia, it was
63.3% in villages, and 93.4% in
schools1,2.

• TSH and UIC are expected to have a negative
correlation to thyroid volume and goiter grade. As
thyroid volume and goiter grade increase, TSH and
UIC levels should decrease.
• Females are expected to have a greater total
agoiter
Mean rate (TGR) than males, with no difference in
classification of nodules.

I would like to sincerely thank Dr. Bridgette Hagerty, and Dr. Richard Daly for making this
project possible through their invaluable guidance and expertise. In addition, I would like to
thank Living Word Community Church and the civilians of Ethiopia for making my pilot study
and the foundational work associated with this project possible.
