Background: Objective of current study was to study association between various interpregnancy intervals and adverse perinatal outcome (preterm birth, low birth weight, small for gestational age) and to come out with optimum interpregnancy interval.
Methods: Retrospective cross sectional study in which 400 meo women (para 2 to para 5) fulfilling inclusion and exclusion criteria having diverse interpregnancy intervals were selected. Statistical analysis was done using SPSS. We used multivariate logistic regression analysis to assess the risk of adverse perinatal outcome.
Results: As compared with infants conceived within a time period of 16 to 48 months after a live birth, infants conceived within 16 months after a live birth had odds ratios of 2.1 (95% CI 1.3 to 3.5) for low birth weight, 2.2 (95% CI 1.3 to 3.8) for preterm birth, and 2.3 (95% CI 1.4 to 3.8) for small size for gestational age; infants conceived more than 48 months after a live birth had odds ratios of 1.88 (95% CI 1.1 to 3.1), 1.96 (95% CI 1.1 to 3.4), and 2.08 (95% CI 1.2 to 3.6) for these three adverse outcomes, respectively; P value
