Mean uterine artery pulsatility index (PI), umbilical artery PI, middle cerebral artery PI, and cerebroplacental ratio were assessed for all third-trimester pregnant women in the program.<\/jats:p><jats:p>\n          Results\u2003From 2019 to 2022, 249 (18.33%, 95% CI: 16.34, 20.54) women had PTB with 221 (16.67%, 95% CI: 14.73, 18.75) PTBs between 34 and 37 gestation weeks and 22 (1.66%, 95% CI: 1.10, 2.50) PTBs at gestation\u2009&lt;\u200934 weeks. The overall preterm birth rates showed a significant (chi-square p\u2009&lt;\u20090.001) declining trend each year from 23.18% (n\u2009=\u2009121) in 2019\u20132020 to 16.81% (n\u2009=\u200999) in
