Description

SALTEST1 (HV234) reports the iodine level in the household's cooking salt, using grouped values. The levels are grouped based on PPM (parts per million).

Universal salt iodization is recommended (by the World Health Organization and UNICEF) to prevent and correct iodine deficiency disorders (including goiter, hypothyroidism, deaf-mutism, mental retardation, dwarfism, stillbirth, and congenital abnormalities). However, unnecessarily high levels of iodine in salt may lead to occasional cases of hyperthyroidism.

The information in SALTEST1 is taken from the household record and applies to regular household residents, not temporary visitors. Researchers may wish to exclude visitors using the RESIDENT variable when women, children, or births are the unit of analysis, and using the HHRESIDENT variable when household members are the unit of analysis.

The related variables SALTEST2 and SALTEST3 (HV234A) also report iodine levels in cooking salt, but with different groupings.

Comparability

SALTEST1 (HV234) has slight differences in the question response categories.

Comparability - Standard DHS

SALTEST1 (HV234) is included in the standard DHS household questionnaire for Phases 4 and 5, but the response categories varied slightly between the phases. Phase 4 allowed response categories of 0 PPM (No iodine), 7 PPM, 15 PPM, and 30PPM. Phase 5 allowed response categories of 0 PPM (No iodine), below 15 PPM, and 15 PPM and above.

To maximize comparability across these different groupings, all response categories falling under the broad heading of "more than 0, less than 15 PPM" share a first digit of 7, while the last digit distinguishes between "7 PPM" (code 70) and "Less than 15 PPM" (code 71). All responses fitting the broad category of "15 PPM or more" share leading digits of 15, while the last digit distinguishes between "15 PPM or more" (code 150) and "30 PPM" (code 151). By grouping categories and ignoring the last digit, all responses can thus be fit into the simpler Phase 5 response categories.

Comparability — Egypt [top]

The 2008 Egypt survey includes "15 PPM or less" and "More than 15 PPM," rather than the more standard "Below 15 PPM" and "15 PPM and above."
