Research on mothers of twins suggests they have a more robust phenotype compared to singleton only mothers. Historical demographic microdata can be additional value in studying differences reproductive behaviour and survival their offspring between multiple birth However, the number such studies historical populations is limited. This study aims explore possibilities maternal life-histories usi...

BACKGROUND Poorly spaced pregnancies have been documented worldwide to result in adverse maternal and child health outcomes. The World Health Organization (WHO) recommends a minimum inter-birth interval of 33 months between two consecutive live births in order to reduce the risk of adverse maternal and child health outcomes. However, birth spacing practices in many developing countries, includi...

OBJECTIVE To re-evaluate the causal effect of interpregnancy interval on adverse birth outcomes, on the basis that previous studies relying on between mother comparisons may have inadequately adjusted for confounding by maternal risk factors. DESIGN Retrospective cohort study using conditional logistic regression (matching two intervals per mother so each mother acts as her own control) to mo...

Human birth interval length is indicative of the level of parental investment that a child will receive: a short interval following birth means that parental resources must be split with a younger sibling during a period when the older sibling remains highly dependent on their parents. From a life-history theoretical perspective, it is likely that there are evolved mechanisms that serve to maxi...

Preterm delivery remains the most important complication of multiple pregnancies. We describe six cases of successful delay of the subsequent child(ren) after very preterm birth of the first-born, with intervals ranging between 14 and 117 days. Based on our findings and on the available literature, we propose a set of guidelines for the management of early preterm multiple birth deliveries, inc...

BACKGROUND The distribution of birth intervals can be used to draw attention to important characteristics of dynamics of fertility process. The main objective of this paper is to examine the effects of socioeconomic, demographic and proximate determinants on the length of birth intervals of women of Bangladesh and also to see whether the effects are changed over the years. METHODS Birth inter...

OBJECTIVE We seek to expand on a biopsychosocial framework underlying the etiology of excess preterm birth experienced by African-American women by exploring short inter-pregnancy intervals as a partial explanatory factor. DESIGN We conducted a qualitative analyses of published studies that met specified criteria for assessing the association of inter-pregnancy interval and preterm birth. M...
