The adjusted odds for the occurrence of a PTB given a previous PTB was 2.58 (95% confidence interval [CI] 2.53\u20132.62). Lower gestational age increased the odds of a subsequent PTB (&lt;28\u00a0weeks: adjusted OR [aOR] 3.61, 95% CI 3.41\u20133.83; 28\u201331\u00a0weeks: aOR 3.34, 95% CI 3.19\u20133.49; and 32\u201336\u00a0weeks: aOR 2.42, 95% CI 2.38\u20132.47). Women who had two previous PTBs were at high risk of having a third (aOR 4.98, 95% CI 4.70\u20135.27). Recurrence of PTB was more likely when the inter\u2010birth interval was less than 12\u00a0months.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In Brazil, a middle\u2010income country, women with a previous PTB had an increased risk of a subsequent one.
