Background: Post-partum haemorrhage (PPH) is one of the classic triad of causes of maternal death. This analysis aimed to evaluate several risk factors of PPH.Methods: This analysis using a cross-sectional Basic Health Research (Riskesdas) 2010 data. For this analysis, the subjects consisted of married women aged 13-49 years, who gave birth of their last child between January 1, 2005 and August 2010, who had a probability of PPH history. The PPH was deﬁ ned as bleeding more than two wet pieces materials, 1.5 m each, during giving birth.Results: This analysis noted 601 subjects had PPH and 19,583 subjects did not have PPH. Post-partum haemorrhage related to demographic (education level, and economic level), gynecologic (parity) as well as obstetric factors. Those who had than did not have eclampsia had 3.5-fold PPH [95% conﬁ dence interval (CI) = 2.53–4.69]. Those who had than did not have premature rupture of the membranes had 2.2-fold PPH (95% CI) = 2.53–4.69). Those who had than did not have placenta previa had 2.1-fold PPH (95% CI) =1.29–3.31). In term of uterine rupture, those who had than did not uterine rupture had 65% increase PPH (95% CI) = 1.11–2.46). Compared to women with 1-2 parity, women with 3-5 and 5 or more parity had an increased PPH risk for 24% and 81% respectively.Conclusion: Eclampsia was the strongest risk factor of PPH. Other risk factors of PPH include premature rupture of the membranes, placenta previa, premature or post-term pregnancies, and high parity. (Health Science Indones 2011;2:66-70).
