Definition
PPAMHMOC (M9) reports the duration, in months, of mother's postpartum amenorrhea after the birth of the child, for children born in the three to five years preceding the survey. Mothers whose period had not returned before the following birth or prior to the interview were included in PPAMHMOC. By contrast, only children of women whose menses had resumed were included in the similar variable PPAMHMO.
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 mother's 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.
For DHS Phase II forward, inconsistent durations based on the original reporting of the duration of amenorrhea were recoded to "Inconsistent" (code "96" in IPUMS-DHS). In cases where the duration was one month longer than the interval, the duration was shortened by one month, consistent with Phase I. For Model "A" countries in Phase II only, if the duration of mother's postpartum amenorrhea extended into her pregnancy in the calendar, the duration was shortened to the start of the following pregnancy.
