Estimating gestational age (GA) is of utmost importance to assess the condition of the fetus. Incorporating placental thickness and fetal biometrics in estimating GA may improve the accuracy of fetal age estimation. The aim of this study was to examine the relationship between placental thickness and GA in pregnant women referred to Al-Zahra Hospital's prenatal and emergency clinic in Rasht, Iran.
This cross-sectional study was conducted on pregnant women referred to Al-Zahra Clinic for prenatal care over a 6-month period. After obtaining informed consent, data were collected on the date of the first day of the last safe menstruation, average body mass index, and medical and surgical history. Placental thickness was estimated using ultrasound and various clinical information was recorded. The data were then analyzed using Pearson correlation analysis in SPSS software version 21.
The results showed a significant correlation between GA and placental thickness ( < 0.0001, = 0.729). Placental thickness increased with increasing GA. There was also a significant relationship between placental thickness and placental location ( = 0.009, = 0.14). In the posterior position, placental thickness increased by 14% or 0.14. The placental thickness in the posterior position (29.49 ± 0.75) was greater than the anterior position (26.94 ± 10.72).
The findings of this study suggest that there is a significant increase in placental thickness with increasing GA during the first and second trimesters. Additionally, placental thickness significantly increased in the posterior placental position, as well as in women with high BMI. Therefore, it is recommended that measuring placental thickness should be routine during obstetric ultrasounds.
估算孕周（GA）对于评估胎儿状况至关重要。将胎盘厚度和胎儿生物测量纳入孕周估算可能会提高胎儿年龄估算的准确性。本研究的目的是探讨转诊至伊朗拉什特市阿尔扎赫拉医院产前和急诊诊所的孕妇胎盘厚度与孕周之间的关系。
本横断面研究对在6个月期间转诊至阿尔扎赫拉诊所进行产前检查的孕妇进行。获得知情同意后，收集末次正常月经首日日期、平均体重指数以及医疗和手术史等数据。使用超声估算胎盘厚度并记录各种临床信息。然后在SPSS 21软件中使用Pearson相关分析对数据进行分析。
结果显示孕周与胎盘厚度之间存在显著相关性（<0.0001，=0.729）。胎盘厚度随孕周增加而增加。胎盘厚度与胎盘位置之间也存在显著关系（=0.009，=0.14）。在后位时，胎盘厚度增加14%或0.14。后位胎盘厚度（29.49±0.75）大于前位（26.94±10.72）。
本研究结果表明，在孕早期和孕中期，胎盘厚度随孕周增加而显著增加。此外，胎盘后位以及高体重指数女性的胎盘厚度显著增加。因此，建议在产科超声检查时常规测量胎盘厚度。
