Availability of adequate iodized salt at household level in rural communities in Farta district, Northwest, Ethiopia: a cross-sectional study

IntroductionIodine is a crucial trace element for thyroid hormone synthesis. All age groups are affected by iodine deficiency disorders (IDD), especially pregnant women, young women, and children. Iodine deficiency disorder has been recognized as a serious public health issue in Ethiopia. Therefore, the aim of the current study was to assess the availability of iodized salt and associated factors at the household (HH) level in the Farta district, northwest, Ethiopia.MethodsA community-based cross-sectional study was conducted involving 704 participants in Farta District, Northwest Ethiopia, between February and March 2021. A multi-stage sampling technique was employed to recruit participants. Data were collected using pretested and structured questionnaires administered by face-to-face interviewers. The data were entered into Epi-data version 4.6 software and exported into Stata version 14 for the purpose of analysis. Both bivariable and multivariable logistic regression analyses were used to identify factors associated with the availability of iodized salt. Statistical significance was declared at a p-value & LE; 0.05 with a corresponding 95% confidence interval.ResultsThe availability of adequately iodized salt in the study area was 26.6% (CI = 23.8%, 29.4%) of households. Good knowledge about iodine deficiency disorder (IDD) and iodized salt (AOR = 3.85, 95% CI: 3.65, 6.11); short-term storage of salt at the HH [AOR = 2.76, 95% CI: 1.98, 3.23); and stored in covered containers (AOR = 1.57, 95% CI: 1.11, 1.78) were significantly associated with the outcome variable.ConclusionThe availability of adequate iodized salt at the HH level was far below the WHO target (more than 90%) in the study area. Knowledge about IDD and iodized salt, stored in covered containers, and short-term storage of salt at the HH were significantly associated with the availability of iodized salt. Hence, at the household level, increasing awareness and disseminating information about the benefits of using iodized salt could be effective. Moreover, education about the proper storage and handling of iodized salt, as well as the recommended storage duration of salt in the home, should be provided as part of our community outreach programs.
