Abstract
Among the three major components of a closed birth interval, waiting time to conception can somehow be managed with effective contraceptives while gestation is universally constant in its duration; the duration of postpartum amenorrhoea (PPA) varies in complex nature. The present study aimed to investigate the proximate factors influencing the duration of PPA. A community-based, cross-sectional study was conducted in four valley districts of Manipur, India, during 1 August-31 December 2009, to analyze the differentials and determinants of duration of PPA, applying the survival analysis technique. In total, 1,225 ever-married women were selected through two-stage cluster sampling. The median duration of PPA was 5.7 months. Among the 11 explanatory variables of interest, only three variables--place of residence (p<0.05), infant mortality from preceding pregnancy (p<0.01), and duration of breastfeeding (p<0.01)--had a significant effect on the duration of PPA. The findings may be used as baseline information for future researchers and maternal health policy-makers.
Highlights
The duration of postpartum amenorrhoea (PPA) is the length of time between the termination of pregnancy and the first successive ovulation following the pregnancy during the reproductive span of a woman
The median duration of PPA increased with the increase in the duration of breastfeeding
The median duration of PPA increased with the increase in parity, and this variation was highly significant (p
Summary
The duration of postpartum amenorrhoea (PPA) is the length of time between the termination of pregnancy and the first successive ovulation following the pregnancy during the reproductive span of a woman. In other words, it is the temporary sterility immediately following the termination of pregnancy during which conception usually does not occur. There is substantial evidence that long-term breastfeeding is associated with a longer anovulatory period leading to prolonged PPA. It reduces fertility even after menses and ovulation have returned
