Guidelines recommend postponing pregnancy for 12\u201324\u00a0months, but optimal surgery-to-conception interval (BSCI) remains uncertain.

We established a cut-off of 24.5\u00a0months of BSCI for lower risk of SGA. Pregnancies conceived in the first 24\u00a0months had a more than tenfold increased risk of SGA (OR 12.6, 95%CI: 2.4\u201366.0), even when adjusted for maternal age, gestational diabetes and inadequate gestational weight gain.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>BSCI was associated with birth weight and SGA.
