While individual maternal chronic conditions are established risk factors, the role of maternal multimorbidity remains underexplored. This study aimed to examine the association between maternal multimorbidity and PTB, and to identify chronic conditions associated with the occurrence and severity of PTB.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective matched case\u2013control study was conducted at Archbishop Makarios III Hospital in Nicosia, Cyprus. The sample included 978 singleton live births, consisting of 489 preterm cases (&lt;37\u00a0weeks) matched 1:1 with 489 term controls (\u226537\u00a0weeks) by maternal age and country of origin. Data were extracted from patient\u2019s medical records. Multimorbidity was defined as the presence of two or more chronic conditions. Conditional logistic regression assessed associations with PTB, and binary logistic regression examined predictors of extreme\/very PTB (&lt;32\u00a0weeks) versus moderate\/late PTB (32 to &lt;37\u00a0weeks).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Maternal multimorbidity was associated with increased odds of PTB (aOR = 1.80; 95% CI: 1.16\u20132.79; p=0.009). Hypertension (aOR=4.26; 95% CI: 1.84\u20139.86), kidney disease (aOR=3.67; 95% CI: 1.01\u201313.30), thrombophilia (aOR=3.53; 95% CI: 1.14\u201310.88), thyroid disorders (aOR = 1.77; 95% CI: 1.05\u20132.98), and allergies (aOR=1.82; 95% CI: 1.12\u20132.99) were independently associated with PTB. Diabetes was inversely associated with extreme PTB (aOR=0.19; 95% CI: 0.10\u20130.92).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Maternal multimorbidity and several chronic conditions are significant and independent predictors of PTB.
