All nulliparous women with a singleton pregnancy and induction of labour at term or in spontaneous labour at term in the index pregnancy were included. Data was extracted from electronic medical records. The outcome of spontaneous preterm birth in the subsequent pregnancy was compared between patients with previous term induction of labour and in previous term spontaneous labour.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec id=\"j_jpm-2021-0111_abs_003\">\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>A total of 907 patients with consecutive births met the inclusion criteria; of which 269 (29.7%) had a term induction of labour and 638 (70.3%) had a term spontaneous labour in the index pregnancy. The overall subsequent spontaneous preterm birth rate was 2.3%. Nulliparous women who underwent term induction of labour were less likely to have a subsequent preterm birth compared to nulliparous women in term spontaneous labour (0.74 vs. 2.98%; odds ratio [OR], 0.25; 95% confidence interval, 0.06\u20131.07; p=0.0496) in the index pregnancy. This however was not significant once adjusted for confounders (adjusted OR, 0.29; p=0.10). Spontaneous preterm birth was associated with a previous spontaneous labour compared to induction of labour between 37 to 37<jats:sup>+6<\/jats:sup> and 38 to 38<jats:sup>+6<\/jats:sup> weeks (adjusted OR 0.18 and 0.21; p=0.02 and 0.004 respectively).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec id=\"j_jpm-2021-0111_abs_004\">\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Term induction of labour does not increase the risk of subsequent spontaneous preterm birth compared to spontaneous labour at term in nulliparous women.
