OBJECTIVE: To estimate the effects on pregnancy outcomes of the duration of the preceding interpregnancy interval (IPI) and type of pregnancy outcome that began the interval. DESIGN: Observational population-based study. SETTING: The Maternal Child Health-Family Planning (MCH-FP) area of Matlab, Bangladesh. POPULATION: A total of 66,759 pregnancy outcomes that occurred between 1982 and 2002. METHODS: Bivariate tabulations and multinomial logistic regression analysis. MAIN OUTCOME MEASURES: Pregnancy outcomes (live birth, stillbirth, miscarriage spontaneous fetal loss prior to 28 weeks, and induced abortion). RESULTS: When socio-economic and demographic covariates are controlled, of the IPIs that began with a live birth, those or = 75 months were associated with increased odds of all three types of non-live-birth (NLB) outcomes but were not as risky as very short intervals. IPIs that began with a NLB were generally more likely to end with the same type of NLB. CONCLUSIONS: Women whose pregnancies are between 15 and 75 months after a preceding pregnancy outcome (regardless of its type) have a lower likelihood of fetal loss than those with shorter or longer IPIs. Those with a preceding NLB outcome deserve special attention in counselling and monitoring.
