Abstract

Objective. Iodine deficiency is a public health problem, especially in Peru, where it affects women of childbearing age and school-age children. The objective of the study was to conduct a household-level analysis of the factors associated with the consumption of table salt with inadequate amounts of iodine in Peru. Design. Analytical cross-sectional study using Peruvian household level data from the Demographic and Family Health Survey (ENDES, 2019). Table salt iodine concentrations were considered as the dependent variable (“inadequate” with iodine levels < 30 PPM and “adequate” with levels ≥ 30 PPM). The association between iodine concentrations in salt and independent variables was evaluated using bivariate and multivariate log-binomial regression models. Setting. Peru. Participants. A total of 25,007 households were included. Results. 21.8% of Peruvian households had inadequate table salt iodine concentrations. Belonging to the poorer and poorest wealth index, living in the Highlands natural region, and living with women of childbearing age with native mother tongue were identified as factors associated with inadequate iodine concentrations in table salt. Conclusions. There is an urgent need to ensure that table salt with adequate iodine concentrations is available for poor populations, residents of the Highlands, and households with ethnic presence. Likewise, it is necessary to promote good storage practices, greater regulation/law enforcement and better monitoring of the companies that manufacture or sell this product. Furthermore, the population needs to be informed of the disorders associated with iodine deficiency.
