A Population-Based Matched-Sibling Analysis Estimating the Associations Between First Interpregnancy Interval and Birth Outcomes

Interpregnancy interval. Association with birth weight, stillbirth, and neonatal death.

Pairs of first and second births and pairs of second and third births to the same Norwegian mothers were studied to determine the association between interpregnancy interval and birth weight, stillbirth, and neonatal death. Use of the pair approach provides one birth which could possibly have been affected by the length of the interval and one birth which could not. The association of interval ...

Re-evaluation of link between interpregnancy interval and adverse birth outcomes: retrospective cohort study matching two intervals per mother

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...

Effect of interpregnancy interval on birth outcomes: findings from three recent US studies.

The relationship between interpregnancy interval and adverse birth outcomes (i.e., low birth weight, preterm birth, and small size for gestational age) was examined in three recent studies conducted in Utah and Michigan of the United States. These studies were conducted among different populations, used different study designs (i.e., cross-sectional and retrospective cohort designs), and addres...
