IntroductionThis study examined bearing perceived stress levels during pregnancy were associated with preterm labor or preterm birth.MethodsPerceived stress levels were measured at 16 weeks'pregnancy or less and between 20 and 24 weeks' pregnancy in a sample of 1069 low-income pregnant women attending Temple University pregnancy care clinics.对评分进行平均，以建立产前压力的单一测量。早产定义为妊娠37周之前发生的自然分娩。早产定义为妊娠20至37周之间发生的与宫颈变化相关的规律宫缩。结果独立于潜在的混杂因素，产前压力感知与早产无关（比值比[OR]，1.10; 95%置信区间[CI]，0.69 - 1.78;P= 0.66）;然而，产前压力倾向于与早产相关（OR，1.49; 95% CI，1.00 - 2.23;P= .05）。早产的最强预测因素是先前妊娠的早产史。有早产史的女性在当前妊娠中发生早产的可能性是无早产史女性的2倍（OR，2.16; 95% CI，1.05 - 4.41;P= .04）。早产的历史风险因素，如非裔美国人种族，堕胎史或早产史，与早产无关。早产的最强预测因子是有早产史（OR，2.55; 95%CI，1.54 - 4.24;P<0.001）.DiscussionPrenatal感知压力水平可能是早产的独立危险因素;然而，产前压力与早产无关。早产的危险因素可能与早产不同。
IntroductionThis study examined whether prenatal perceived stress levels during pregnancy were associated with preterm labor or preterm birth.MethodsPerceived stress levels were measured at 16 weeks’ gestation or less and between 20 and 24 weeks’ gestation in a sample of 1069 low‐income pregnant women attending Temple University prenatal care clinics. Scores were averaged to create a single measure of prenatal stress.Preterm birthwas defined as the occurrence of a spontaneous birth prior to 37 weeks’ gestation.Preterm laborwas defined as the occurrence of regular contractions between 20 and 37 weeks' gestation that were associated with changes in the cervix.ResultsIndependent of potential confounding factors, prenatal perceived stress was not associated with preterm labor (odds ratio [OR], 1.10; 95% confidence interval [CI], 0.69‐1.78;P= .66); however, prenatal stress trended toward an association with preterm birth (OR, 1.49; 95% CI, 1.00‐2.23;P= .05). The strongest predictor of preterm labor was a history of preterm labor in a prior pregnancy. Women with a history of preterm labor were 2 times more likely to experience preterm labor in the current pregnancy than women who did not have a preterm labor history (OR, 2.16; 95% CI, 1.05‐4.41;P= .04). Historical risk factors for preterm birth, such as African American race, a history of abortion, or a history of preterm birth, were not related to preterm labor. The strongest predictor of preterm birth was having a history of preterm birth in a prior pregnancy (OR, 2.55; 95% CI, 1.54‐4.24;P< .001).DiscussionPrenatal perceived stress levels may be a risk factor for preterm birth independent of preterm labor; however, prenatal stress was not associated with preterm labor. Risk factors for preterm labor may be different from those of preterm birth.
