Household Salt Iodine Level and Associated Factors in Dire Dawa City Administration, Eastern Ethiopia
Background: Iodine is the commonest, but not the only, cause for the low level of thyroid hormones. Salt iodization is the preferred strategy to control this Deficiency Disorder. However, there is limited information on the level of iodine on household salt and the associated factors in Dire Dawa city administration. The main aim of this study was to assess the level of iodine in the household salt and associated factors in Dire Dawa City Aadministration. Methods: Community based cross-sectional study was conducted in Dire Dawa City Administration among randomly selected 402 households. The level of iodine was determined by using rapid test kit and iodometric titration test. Data were collected by structured questionnaire using face to face interview on socio-demographic, economic dietary diversity, salt storage and utilization. The data were entered in to EpiData Version 3.1 and exported to SPSS Version 20.0 for analysis. All the variables that had P<0.25 with outcome variable in the bivariate analysis were included in the multivariate regression model, and P-value ≤ 0.05 was declared as statistically significant. Results: Inadequate amount of iodized salt (<15 parts per million) was found among 51% of the households and 49.5% of the households’ salt had inadequate (less than 20 mg/kg) iodine concentration using Iodometric titration test. Using non-packed salt (AOR=1.3; 95% CI: 1.1-4.73), knowledge about the importance of iodized salt (AOR=2.3; 95% CI: 1.05-4.90), storing the salt for more than two months (AOR=2.1;5% CI: 1.14-4.61), purchasing salt from open market (AOR=2.3; 95% CI: 1.1-6.5) and retail shop (AOR=1.6;95% CI:1.1-5.1), and divorced, widowed and separated (AOR=2.93; 95% CI: 1.56-6.59) were significantly associated with the availability of inadequate iodized salt at the households. Conclusions: In the study area, many of the households did not have access to adequately iodized salt at the household level. Hence, the concerned stakeholders should sensitize the community about the importance of iodized salt and its proper handling at the household level.
