目的:总结10年来剖宫产率的变化趋势与产妇的生育年龄、婴儿出生体重的关系。方法:回顾性分析了1997~2006年3785例产妇的临床资料。结果:①剖宫产率呈逐年上升趋势。1997年剖宫产率最低,为33.86%,2006年剖宫产率最高,为69.77%,两者比较差异有显著性(P0.05)。尤其是近5年剖宫产率上升趋势加快,5年间上升了15.00%。②10年来,随着≥30岁产妇人数的逐年增多,剖宫产率也随之相应增高,两者呈正相关。2006年≥30岁分娩人数和剖宫产人数均明显高于1997年(P0.05)。③10年间婴儿出生体重与剖宫产率的构成无显著性差异(P0.01)。结论:降低剖宫产的比例势在必行,加强对育龄妇女孕育知识的教育,选择最佳生育年龄,减少巨大儿的出生,对母婴健康及降低剖宫产率均有积极的意义。  相似文献

Purpose

Short interpregnancy interval (IPI) has been linked with adverse birth outcomes. However, the association in advanced age women needs further investigation. This study aims to examine the association between short IPI and adverse birth outcomes including preterm birth, post-term birth, low birth weight, and macrosomia, in a population of advanced age U.S. women.

Methods

The 2016 U.S. public-use natality data was analyzed. Analysis was restricted to women with second-order singleton live births who were ≥35 years at first live birth (n = 46,684). Multinomial logistic regression analysis was used to examine the association between short IPI and adverse birth outcomes.

Results

Short IPI in advanced age women was significantly associated with higher odds of extremely preterm birth (0–5 months IPI: adjusted odds ratio [AOR] = 2.43, 95% confidence interval [CI] = 1.07–5.52; 6–11 months IPI: AOR = 2.17, 95% CI = 1.09–4.31), very preterm birth (0–5 months IPI: AOR = 1.63, 95% CI = 1.04–2.56), and extremely low birth weight (0–5 months IPI: AOR = 2.43, 95% CI = 1.28–4.60) in the second delivery. An inverse relationship between short IPI and post-term birth was observed and no significant association between short IPI and macrosomia was found.

Conclusions

Short IPI in advanced age women increases the odds of adverse birth outcomes in the second delivery.  相似文献

BackgroundPregnant women are recommended to receive inactivated influenza vaccination anytime during pregnancy. Studies have investigated the impact of influenza vaccination during pregnancy on birth outcomes and results on preterm birth have been inconsistent.MethodsWe conducted a retrospective cohort study among children born at a gestational age  24 weeks from January 1, 2010 to December 31, 2015 at Kaiser Permanente Northern California facilities (KPNC). We evaluated the association between maternal influenza vaccination during pregnancy and risk of preterm birth, small and large for gestational age, admission to the neonatal intensive care unit (NICU), respiratory distress syndrome, low birth weight, and low Apgar score. We ascertained the dates of maternal influenza vaccination, conception, and delivery, as well as birth outcomes from KPNC inpatient and outpatient databases. Conditional multivariate Cox regression and logistic regression analyses were used to determine the association between maternal vaccination during pregnancy and risk of each birth outcome.ResultsThe study included 145,869 children. Maternal influenza vaccination during pregnancy was not associated with risk of small or large for gestational age births, preterm birth, need for mechanical ventilation at birth, respiratory distress syndrome, admission to the NICU, low birth weight, or low Apgar score. However, when we did not control for immortal time bias, the risk of preterm birth (odds ratio [OR] = 0.69, 95% confidence interval [CI] 0.66–0.72) was lower among infants of vaccinated mothers.ConclusionWe found no association between maternal influenza vaccination during pregnancy and adverse birth outcomes. When investigating preterm birth outcome in association with vaccination during pregnancy, immortal time bias should be taken into account in the analysis.  相似文献

ObjectiveInfluenza vaccination during pregnancy is highly recommended. We examined the association between maternal influenza vaccination and adverse birth outcomes.MethodsThis cross-sectional study used data from the Pregnancy Risk Assessment Monitoring System (PRAMS) during 2012–2017. The primary exposure was the receipt of influenza vaccination during pregnancy. Low birth weight (LBW), preterm birth (PTB), and small for gestational age (SGA) were the primary outcomes. We conducted multivariable logistic regression models to estimate the adjusted odds ratios (AOR) and 95% confidence intervals (CI). Covariates used to adjust confounding included maternal age, marital status, education, race and ethnicity, insurance status before pregnancy, and smoking status. For a subgroup in 2012–2015, we analyzed the association between influenza vaccination in each trimester and adverse birth outcomes.ResultsDuring 2012–2017, compared with unvaccinated women, women vaccinated during pregnancy had a lower risk of LBW and PTB. During 2012–2015, maternal influenza vaccination in the 1st and 3rd trimesters was associated with a reduced risk of LBW and PTB, and vaccination in the 3rd trimester had a greater protective effect than in the 1st trimester. Influenza vaccination was not associated with SGA regardless of trimester.ConclusionsOur findings suggest that influenza vaccination during pregnancy is a safe and effective way to protect newborns.  相似文献

Objectives

This study measured the impact of shifts in maternal age and parity on the increase in the low birth weight (LBW) rate in Korea.

Methods

We obtained raw data for all 6 397 945 live births registered at the Korea National Statistical Office between 1995 and 2005. We calculated the proportion of increment in the LBW rate due to changes in the distribution of maternal age and parity (AP-dis) and the proportion due to changes in the age- and parity-specific LBW rate (AP-spe).

Results

The LBW rate increased from 3.02% in 1995 to 4.28% in 2005. The multiple birth rate increased from 1.32% to 2.19% during the same period. Of the 1.26% points increment in the LBW rate, 0.64% points occurred among singleton births and 0.62% points occurred among multiple births. Changes in the AP-dis accounted for 50% of the increase in the LBW rate among singleton births, but did not contribute to the increase in the LBW rate among multiple births. The remainder of the total increment in the LBW rate was explained by the increase in the AP-spe.

Conclusions

This study demonstrated that shifts in maternal age and parity among singleton births and increased multiple births were important contributors to the increment in the LBW rate. This study also revealed that the increase in the AP-spe was an equally important contributor as the shifts in maternal age and parity to the increment in the LBW rate among singleton births and was a major contributor among multiple births.  相似文献

新生儿早产、低出生体重及小于胎龄的危险因素   总被引:2,自引:1,他引:2       下载免费PDF全文
目的 研究早孕期相关暴露因素与新生儿早产、低体重及小于胎龄的关系。方法 选取“中国孕产妇队列研究·协和”项目于2017年7月25日至2018年7月24日入组并于2018年12月31日前分娩且符合纳入标准的3 172例孕妇为研究对象,使用二分类logistic回归分析对早孕期相关暴露因素与新生儿不良分娩结局的关系进行统计分析。结果 新生儿早产、低体重及小于胎龄的发生率分别为4.76%、3.53%、5.74%。在早产方面,北方孕妇和孕期增重是早产的保护因素,而胎膜早破、妊娠期高血压、1~3年内有口腔检查或治疗、家庭人口为3~4人是早产的危险因素。在低出生体重方面,孕期增重和食用奶及奶制品是低出生体重儿的保护因素,而胎膜早破、妊娠期高血压、工作久坐时间>6 h、1~3年内有口腔检查或治疗、被动吸烟等是低出生体重儿的危险因素。在小于胎龄方面,女婴、被动吸烟、食用花生油及口味偏淡是小于胎龄儿的危险因素,而补充叶酸是小于胎龄儿的保护因素。结论 新生儿早产、低体重及小于胎龄的影响因素是多因素的,应针对相关危险因素采取有针对的预防和干预措施以降低新生儿不良出生结局的发生风险。  相似文献

Purpose

Much less is known about the effect of advanced paternal age (APA) (≥40 years) than advanced maternal age on neonatal morbidity. More specifically, the correlation with low birth weight remains inconsistent. This study aims to determine whether APA among mothers aged 20–29 years is associated with a higher risk of low birth weight and other neonatal outcomes.

Methods

Data from 2004 to 2008 database of the National Collaborative Perinatal Neonatal Network were used. Fifteen thousand two hundred eighteen live birth singleton pregnancies by primigravida mothers aged 20–29 years were analyzed. Study variables include paternal age (years), C-section delivery (yes/no), low birth weight (<2500 g), and preterm births (<37 weeks of gestation). Regressions were generated controlling for birth defects, consanguinity, maternal education, prenatal care, gender, and maternal smoking.

Results

Adjusted odds of Low Birth Weight (LBW) and Cesarean Section Deliveries (CSD) were significantly higher in infants of APA fathers compared to those of fathers aged 30–35 years [adjusted odds ratio (95% confidence interval) = 1.5 (1.1, 2.3) and 1.4 (1.1, 1.7), respectively]. Paternal ages of 35–39 years compared to less than 30 years were associated with higher odds of CSD [adjusted odds ratio = 1.4 (1.2, 1.5)]. APA was not associated with preterm birth after adjustment.

Conclusions

This study supports the association between APA and increased risk for LBW and CSD.  相似文献
