Definition
For women who gave birth in the 5 years before the survey, PNBABCK_ALL (M70_x) indicates whether the woman's baby had a postnatal check within 2 months of delivery.
For most surveys, this information on postnatal checks for the child is collected for only the last-born child (PNBABCK_01). For a minority of samples, noted in the Comparability section, the information was collected for all births within the 3 to 5 years before the survey.
To accommodate those surveys that collected this information on multiple births, PNBABCK_ALL consists of a set of six separate variables, covering the most recent birth (PNBABCK_01) up to the sixth-most-recent birth (i.e., PNBABCK_02, PNBABCK_03, PNBABCK_04, PNBABCK_05, and PNBABCK_06) during the reference period prior to the survey. If PNBABCK_ALL is included in a data extract, all these separate variables--when available--are included in a researcher's data file.
In some cases, data were hypothetically collected on up to six births, but no women in the survey had so many births (e.g., no woman had 4 or more births in 3 years, or had 5 or 6 births in 5 years). If, in a survey that collected this information for more than the most recent birth, no woman had 6 births in five years and only blank values were included in the original DHS file, then PNBABCK_06 would not be available for that survey in IPUMS-DHS.
