Socio-demographic correlates of availability of adequate iodine in household salt: a community-based cross-sectional study.

Objective: This study aimed to assess the availability of adequately iodized salt at a household level and associated factors in Arba Minch town, South Ethiopia using the gold standard technique, the iodometric titration.

Results: 41.8% (95% CI (confidence interval) 38.6 to 45.1) of households had inadequately iodized salt, and 9.3% (95% CI 7.5 to 11.4) had an iodine content below 10 ppm (parts per million). Compared to households with a monthly income of greater than 2000 ETB (Ethiopian Birr), households with a monthly income between 1000 ETB to 2000 ETB (adjusted odds ratio (AOR) = 0.52, 95% CI 0.390.36 to 00.77) and main food handlers aged 30 years or above compared to those aged less than 20 years of age (aOR = 0.55, 95% CI 0.34 to 0.91) had higher odds of having adequately iodized salt. Food handler's knowledge and practice were not found to be correlated with the availability of adequately iodized salt in household salt.
