Definition
For women who gave birth in the last three to five years, ANNITE_ALL (M48_x) indicates whether they had difficulty with night blindness.
ANNITE_ALL consists of separate variables, covering the most recent birth (ANNITE_01) and, in some cases, additional births, up to, potentially, the sixth-most-recent birth (i.e., ANNITE_02, ANNITE_03, ANNITE_04, ANNITE_05, and ANNITE_6). For most surveys, this information on night blindness during pregnancy was collected for only the most recent birth; exceptions are noted in the comparability section.
