Household use of iodized salt in rural area

Iodine deficiency is the world's single greatest cause of preventable mental retardation. In developing countries, only 69% of households are consuming iodized salt.

To assess knowledge and practices with respect to the current use of iodized salt, and to estimate its uptake at the household level.

This cross-sectional survey was conducted in six villages under Rural Health Training Center. A total number of households surveyed were 253. The data collectors obtained verbal consent from the Family, and Pretested Standardized Questionnaire was administered in every selected household. The respondents were asked questions regarding salt purchasing and consumption habits, salt storage, awareness of iodized salt, and iodine deficiency diseases. Rapid iodized salt test kit (MBI kit) was used in the survey to assess iodine content in salt used in households.

In this study, 93.7% households were using packet salt. The most common source of information was a television (31.1%). More than half (53.8%) of the households were unaware of the benefits of iodine. About 62.5% of households were consuming adequately iodized salt. Significant association was found between the practice of storing salt in closed containers and use of packaged iodized salt (Chi-square value -37.6, P < 0.001), awareness about the benefits of iodine and type of salt used (P = 0.02) while no association was observed between the socioeconomic status and type of salt used in the household.

Though the use of packet salt was more than 90%, adequately iodized salt was consumed only in 62.5%, and more than half of the subjects lacked the knowledge about iodine deficiency diseases.
