Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
For children born in the three to five years before the survey, PPAMHMO (M6) reports the duration, in months, of the mother's postpartum amenorrhea after delivery of the child. Children whose mothers' periods had not returned at the time of interview were excluded from PPAMHMO, but children whose mothers were still amenorrheic were included in calculations for the similar variable PPAMHMOC (M7).
The maximum period allowed during the data editing (by the survey administrators) was the interval between the date of birth of the child and the date of conception of the following child (with birth date minus nine months used for the date of conception) or the date of interview if there was no following birth.
