Iodine deficiency disorder (IDD) is currently an important public health pr
oblem in Turkey. The use of iodized salt is a simple and cheap solution. Th
e purpose of this study was to determine the prevalence of iodized salt use
in the Trabzon region and the effect of a local mass-media education progr
am in increasing usage. The overall aim was to use the findings to inform f
uture health management and health education activities, and shape further
development of the IDD program. Prior to the intervention, the prevalence o
f iodized salt consumption was 54.5%. Following the 3-month education progr
am it increased to 62.4%. There was a significant difference in the pre- an
d post-intervention findings (P = 0.00237). The results show that the use o
f local mass media is effective in raising the prevalence of iodized salt u
se. Local mass media could therefore be used as part of a national strategy
to prevent iodine deficiency disorders.
