Increased maternal age, excessive oxidative stress and inflammation are involved in the pathophysiology of COD and enhance telomere length (TL) shortening. We investigated the association between periconception maternal TL and the risk of having a child with COD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>From a multicentre case\u2010control trial, 306 case mothers of a child with COD and 424 control mothers of a child without a congenital malformation were selected. Relative TL was measured by qPCR. Multivariable logistic regression was used to compute crude and adjusted odds ratios, per standard deviation decrease, between maternal T\/S ratio and COD and VSD risk. Adjustments were made for maternal age. Additional adjustments were made in a second model.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Shorter maternal relative TL was significantly associated with an OR of 1.29 (95% CI 1.04\u20131.61), <jats:italic>p<\/jats:italic>\u00a0=\u00a0.02, for the risk of VSD in offspring, which remained significant after an adjustment for maternal age (adjOR 1.25(95% CI 1.01\u20131.55), <jats:italic>p<\/jats:italic>\u00a0=\u00a0.04).
