Magnitude and factors associated with Availability of Adequately Iodized Salt at Households of Pregnant Mothers in Wonago district, south Ethiopia
Abstract Background Salt iodization is the most cost-effective, safe and sustainable strategy to eliminate iodine deficiency disorders. It is especially damaging during pregnancy and in early child hood. Adding iodine to salt provides protection from brain damage due to iodine deficiency for whole populations. However, little was known about the availability of adequately iodized salt in South Ethiopia. The aim of this study was to assess prevalence and factors associated with availability of adequately iodized salt at the households of pregnant mothers in Wonago District, South Ethiopia, 2018. Methods Community-based cross-sectional study was conducted from May 14-29, 2018 in Wonago district. Using a stratified two stage random sampling technique, a total of 604 pregnant mothers were included in the study. The level of salt iodine content was determined using the rapid field test kit, considering a value of <15 parts per million (PPM) and ≥15 PPM with the corresponding color chart on the rapid test kit for classification. Multivariable logistic regression model was fitted to identify factors associated with the availability of adequately iodized salt. Adjusted Odds Ratio (AOR) with the corresponding 95% Confidence Interval (CI) was calculated to show the strength of association. Result Availability of adequately iodized salt at households of pregnant mothers was 19.9%. House hold head, husband education, average monthly household income and time of salt addition during cooking were independently associated with adequately iodized salt availability. Accordingly, participatory male headed households [AOR=2.1(95%CI 1.08, 3.96)], women with an average monthly household income of ≥ 817 ETB [AOR=7.3(95%CI 3.03, 17.70)] and those who added salt late or after cooking during food preparation [AOR=2.17(1.08, 4.38)] were more likely to utilize adequately iodized salt. Conversely, women whose husband had no formal education were less likely [AOR=0.33(95%CI 0.11, 0.88)] to utilize iodized salt. Conclusion Compared to the recommended standard, use of adequately iodized salt among pregnant women is very low. Paternal conditions and household income level are key predictors of use of adequately iodized salt.
