摘要：Background. Iodine is one of the essential elements that enables the thyroid gland to produce thyroid hormones, which is vital for growth and development of the brain and central nervous system. More than two billion individuals worldwide live in iodine-deficient areas. Objectives. The aim of this study was to assess knowledge and utilization of iodized salt at the household level and associated factors in the Mecha district, Northwest Ethiopia. Methods. A community-based cross-sectional study was conducted from March 10 to April 10, 2018. Data were collected using a pretested and structured questionnaire by a face-to-face interview technique. The use of iodized salt at the household level was tested with the iodine rapid test kit. Data were checked, coded, and entered to EPi Info version 3.5.1 and were exported to SPSS (Statistical Package for Social Science) version 20 for analysis. Result. A total of 700 head of households were included in the study, of which 639 (91.3%) were females. The overall prevalence of knowledge was 201 (28.7%). Availability of adequately iodized salt was 443 (63.3%). The proportion of proper utilization of adequately iodized salt at the household level was 180 (25.7%). Occupational status, educational status, and residence were predictors of knowledge on the use of iodized salt. Educational status, packaging, and knowledge of respondents on iodized salt were significant to utilization. Conclusion and Recommendation. Knowledge, availability, and utilization of adequately iodized salt remain very low in the district. Concerned body should improve awareness and availability of adequately iodized salt and how to utilize it properly.
