ANBLRVIS_ALL variables are 1-digit variables.
0 = No
1 = Yes
7 = Don't know
8 = Missing
9 = NIU (not in universe)
ANBLRVIS_ALL indicates whether the woman experienced blurred vision while pregnant.
ANBLRVIS_ALL consists of separate variables, covering the most recent birth (ANBLRVIS_01) and, in some cases, additional births (potentially, ANBLRVIS_02, ANBLRVIS_03, ANBLRVIS_04, ANBLRVIS_05, and ANBLRVIS_06). For most surveys, this information on blurred vision as a pregnancy complication was collected for only the most recent birth; exceptions are noted in the comparability section.
The related variable ANVISION_ALL (M47_x) indicates whether the woman had difficulty with daylight vision while pregnant.
Comparability — Index
Apart from universe differences and slight differences in question wording, ANBLRVIS_ALL is largely comparable across samples.
