Pregnancy is one of the most important periods of a woman's life and is influenced by many different factors. For years, it was assumed that teenage pregnancy can cause poor pregnancy outcome. The purpose of this study was to compare some pregnancy complications between 2 groups of 15 to 19 and 20 to 35 year- old primigravida pregnant women This was a cross- sectional study conducted on the data sheets of primigravida women who delivered their babies in a teaching hospital. A total of 3040 eligible women entered the study; of them, 280 (9.3%) were in the 15 to 19 years age group and 2756 in the 20 to 35 years age group. The 2 groups were compared for preeclampsia, PROM, preterm birth, SGA, placental abruption, and placenta previa. A logistic regression model was used for data analysis. The women of the 2 groups significantly differed in BMI and socioeconomic background. The rate of preeclampsia (p=0.008), PROM (p=0.002), and preterm delivery (p=0.001) were less in the 15 to 19 years age group. The rate of placental abruption, placenta previa, IUFD, and SGA was not significantly different between the 2 groups. After multivariate regression analysis, preeclampsia (adjusted odd ratio= 2.157; 95% CI= 1.38- 4.21) and preterm delivery (adjusted odd ratio= 2.443; 95% CI= 1.78- 5.13) were found to be higher in the 20 to 35 years group. The risk of poor pregnancy outcome is not higher in teenage pregnancies compared to pregnancies in the 20 to 35 years age group if confounding factors, including socioeconomic factors, are carefully controlled.
怀孕是女性生命中最重要的时期之一，会受到许多不同因素的影响。多年来，人们一直认为少女怀孕会导致不良妊娠结局。本研究的目的是比较两组15至19岁和20至35岁初产妇孕妇的一些妊娠并发症。这是一项横断面研究，基于在一家教学医院分娩的初产妇的数据表进行。共有3040名符合条件的女性进入研究；其中，280名（9.3%）在15至19岁年龄组，2756名在20至35岁年龄组。比较两组的子痫前期、胎膜早破、早产、小于胎龄儿、胎盘早剥和前置胎盘情况。采用逻辑回归模型进行数据分析。两组女性在体重指数和社会经济背景方面存在显著差异。15至19岁年龄组的子痫前期发生率（p = 0.008）、胎膜早破发生率（p = 0.002）和早产发生率（p = 0.001）较低。两组之间的胎盘早剥、前置胎盘、胎儿宫内死亡和小于胎龄儿发生率无显著差异。多变量回归分析后发现，20至35岁年龄组的子痫前期（调整后的比值比 = 2.157；95%置信区间 = 1.38 - 4.21）和早产（调整后的比值比 = 2.443；95%置信区间 = 1.78 - 5.13）发生率较高。如果包括社会经济因素在内的混杂因素得到仔细控制，与20至35岁年龄组的妊娠相比，少女怀孕时不良妊娠结局的风险并不更高。
