Focus has now shifted to pre-pregnancy counselling to optimise body weight before subsequent conception. We aimed to assess the effect of interpregnancy body mass index (BMI) change on the risk of perinatal complications in the second pregnancy.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A cohort study was performed using pooled maternity data from Aberdeen, Finland and Malta. Women with a BMI change of \u00b12\u2009kg\/m<jats:sup>2<\/jats:sup> between their first and second pregnancies were compared with those who were BMI stable (remained within \u00b12\u2009kg\/m<jats:sup>2<\/jats:sup>). Outcomes assessed included pre-eclampsia (PE), intrauterine growth restriction (IUGR), preterm birth, birth weight, and stillbirth in the second pregnancy. We also assessed the effect of unit change in BMI for PE and IUGR. Logistic regression was used to calculate odds ratios with 95% confidence intervals.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>An increase of \u22652\u2009kg\/m<jats:sup>2<\/jats:sup> between the first two pregnancies increased the risk of PE (1.66 (1.49\u20131.86)) and high birthweight (&gt;4000\u2009g) (1.06 (1.03\u20131.10)). A reduction of \u22652\u2009kg\/m<jats:sup>2<\/jats:sup> increased the chance of IUGR (1.15 (1.01\u20131.31)) and preterm birth (1.14 (1.01\u20131.30)), while reducing the risk of instrumental delivery (0.75 (0.68\u20130.85)) and high birthweight (0.93 (0.87\u20130.98)). Reducing BMI did not significantly decrease PE risk in women with obesity or those with previous PE. A history of PE or IUGR in the first pregnancy was the strongest predictor of recurrence independent of interpregnancy BMI change (5.75 (5.30\u20136.24) and (7.44 (6.71\u20138.25), respectively).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Changes in interpregnancy BMI have a modest impact on the risk of high birthweight, PE and IUGR in contrasting directions.
