3. Résumé


« Our study confirms the results of other studies that have found marital status and IPI [Interpregnancy interval] to be associated with adverse birth outcomes, and provides additional insights on factors contributing to SGA [small for gestational age] birth. First, by including neighborhood factors as explanatory variables, we were able to demonstrate that the influence of the IPI on SGA birth varies according to features of the neighborhood. This finding is consistent with the growing literature on neighborhoods and health. Second, through testing for effect modification between individual predictor variables, we demonstrated that the association between IPI and SGA birth depends on maternal marital status. We also showed that the association between marital status and SGA birth varied according to IPI and maternal place of origin (Canadian-born versus foreign-born). » (pp. 4-5)
