Postpartum amenorrhoea among Manipuri women: A survival analysis

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. © international centre for diarrhoeal disease research,bangladesh.
