WHO report that in 2002 there were an estimated 605 million older persons in the world, nearly 400 million of whom were living in low-income countries, by 2025, the number of older persons worldwide is expected to reach more than 1.2 billion, with about 840 million of those in low-income countries [1].
When we see about the awareness of the people in the world it is low due to that the peoples are suffered from goiter disease and other problems related to iodized and this problem are also faced in our country especially in Tigray Mekelle city. Despite numerous educational programmers to create awareness about iodized salt and iodine deficiency disorders (IDD), a survey conducted in the in Mekelle in 2012 revealed that the goiter rate stood at 18.8%; and 78.1% of households consumed iodized salt, which is below the goal of the IDD programme in Ethiopia which aimed at 90% household consumption of iodized salt by the end of 2015 and sustaining the gains by 2012.
