There is a linear association (\u03c7<jats:sup>2<\/jats:sup> for linear trend, <jats:italic>P<\/jats:italic> &lt; 0.001) between maternal corpulence and risk of caesarean deliveries, the leanest mothers having the best rate of vaginal delivery. This linear association exists in a model controlling for diagnosis of gestational diabetes, term deliveries (\u226537 weeks), very short maternal height (&lt;1.50 m), primiparity and maternal age \u2265 35 years (adjusted \u03c7<jats:sup>2<\/jats:sup>, <jats:italic>P<\/jats:italic> &lt; 0.001).<\/jats:p><jats:p><jats:bold>Conclusion\u2002<\/jats:bold> There is a significant linear association between pre\u2010pregnancy maternal corpulence and risk of caesarean deliveries in pregnancies at term.
