Definition
MAFEDSALT24H indicates whether the child's mother gave her youngest surviving child salty snacks during the previous day, either at night or during the daytime. This variable describes a characteristic of the mother rather than the child.
Although the question wording asks about foods given to a specific child during the previous day, responses relate to the mother, so all young children of the mother are coded the same way. If the mother reported she gave her youngest surviving child salty snacks in the previous day, all of her young children in the data are coded as "yes," including any children who have died or who live elsewhere.
A positive response in MAFEDSALT24H thus does not necessarily indicate whether a particular child of the mother ate salty snacks during the previous day.
