IODINE AND THYROID STATUS IN A TRIBAL VILLAGE IN WAYANAD, KERALA IN THE POST IODIZATION ERA – OBSERVATIONS AND IMPLICATIONS
Background: Data on thyroid and iodine status in tribal population is scarce. We sought to assess the thyroid and iodine status in this population, by ascertaining the goitre prevalence, thyroid function and thyroid autoimmune markers in adults, and the goitre prevalence and iodine status in school...

| Shrnutí: | Background: Data on thyroid and iodine status in tribal
population is scarce. We sought to assess the thyroid and iodine
status in this population, by ascertaining the goitre prevalence,
thyroid function and thyroid autoimmune markers in adults, and
the goitre prevalence and iodine status in school going children
from both tribal and non tribal populations
Methods: Questionnaire survey and physical examination was
done in 50 randomly selected houses from both tribal and non-
tribal
populations.
Goitre,
thyroid
function,
thyroid
autoimmunity was assessed in 175 adults and goiter and iodine
status were assessed in 83 children.
Results: Goitre prevalence was similar in tribal and non- tribal
adults ( tribal ,45.7% vs. nontribal , 42%,P 0.87) and children
(14.9% and 19.4%, P=0.77) . Goitre prevalence was more in adult
females . Thyroid dysfunction was seen in 3.9% of tribal and 4.2%
of non-tribals. Abnormal thyroid function tests were all in the
thyrotoxic range in tribals whereas they were all in the
hypothyroid range in non-tribal. Thyroid autoimmunity was
more in the non-tribal Compared to tribal population ( 24.7% vs.
10.6% p =0.026).
Conclusions: This is the first data on thyroid status in tribal and
non-tribal population from Wayanad district, which has shown a
high adult prevalence of goitre. However the prevalence of goitre
in children is near the national average, which might indicate an
improvement in the iodization status in the post iodization era.
The higher prevalence of hyperthyroidism in tribals and
significant difference in thyroid autoimmunity between tribals
and non -tribals merit further study. |
