Nearly one-in-five households utilized inadequate iodized salt in Nifas Silk Sub-City, Addis Ababa, Ethiopia

Abstract Background There is no country in the developing world where iodine deficiency is not a public health problem including Ethiopia. Therefore, this study aimed to assess inadequate utilization of iodized salt and associated factors at household level in woreda 11 Nifas Silk Sub-city, Addis Ababa, Ethiopia. Methods A community-based cross-sectional study was conducted with multistage sampling technique on 348 household respondents. The data were collected using interviewer-administered structured questionnaires and an iodine rapid test kit. The data were edited, cleaned, and entered using Epi-data version 4.6.2 and exported to SPSS version 25 for analysis. A multivariable logistic regression model was fitted to identify associated factors for inadequate utilization of iodized salt. The statistical significance was declared at a p-value of less than 0.05 with 95% confidence interval. Results A total of 348 household respondents were participated. The amount of iodine content in salt 0 ppm, < 15ppm and > 15ppm were 11.8%, 7.2% and 81.0% respectively. Total inadequate utilization of iodized salt was 19%. Using unpacked salt [AOR; 0.50 (95%CI: 0.27, 0.93)], using a container without a lid [AOR; 0.29 (95%CI: 013, 0.63)], and having insufficient knowledge [AOR; 2.10 (95%CI: 1.14, 3.86)] were all significantly connected with using inadequate iodized salt. Conclusions Iodized salt utilization was inadequate. Using containers without a lid, unpacked salt, and poor knowledge were associated factors. There should be a provision of adequate knowledge about iodized salt, a proper storage and handling.
