The correlation between placental thickness, gestational age and fetal weight across different stages of pregnancy is of interest. Hence, 187 women (11-40 weeks gestation) at Maa Vindhyavasini Autonomous State Medical College and SMMH Medical College in India participated in this study. Results showed that mean placental thickness increased with gestational age (2.083 cm at 11-20 weeks, 2.623 cm at 20-30 weeks and 3.29 cm at 30-40 weeks), while fetal weight also increased (172.05g, 746.67g and 2584.49g, respectively). A strong positive correlation was found between gestational age and both fetal weight and placental thickness, except during early pregnancy (11-21 weeks), with statistical significance at the 5% level. Thus, the correlation between placental thickness, fetal weight and gestational age in 187 pregnant women, showing strong positive correlations, especially in later stages of pregnancy is reported.
孕期不同阶段胎盘厚度、孕周与胎儿体重之间的相关性备受关注。因此，印度马阿温迪亚瓦西尼自治邦医学院和SMMH医学院的187名孕妇（孕周为11 - 40周）参与了本研究。结果显示，平均胎盘厚度随孕周增加而增加（11 - 20周时为2.083厘米，20 - 30周时为2.623厘米，30 - 40周时为3.29厘米），同时胎儿体重也增加（分别为172.05克、746.67克和2584.49克）。除了孕早期（11 - 21周）外，孕周与胎儿体重及胎盘厚度之间均存在强正相关，在5%水平具有统计学意义。因此，报告了187名孕妇胎盘厚度、胎儿体重与孕周之间的相关性，显示出强正相关，尤其是在妊娠后期。
