1题目：孕期保健对高龄产妇妊娠结局和并发症影响的研究进展摘要基于中国二胎政策的开放和社会生育观念的变化，高龄产妇人数呈大比例上升，她们在机体和心理上要比适龄产妇差。孕期保健是一项可以有效预防并减少孕期并发症，开展出生缺陷筛查，及早进行干预，最终确保母婴安全的重要措施。它不仅能让产妇对妊娠有一个正确的的认识，还能极大地改善产妇的分娩体验。本研究将通过回顾多篇文献进行对比分析，综述孕期保健对高龄产妇妊娠结局及并发症的影响，为进一步改善高龄产妇妊娠及分娩体验提供参考。关键词：高龄产妇；孕期保健；妊娠结局；并发症2ABSTRACTDuetotheopeningofChina’ssecond-childpolicyandchangesinsocialfertilityconcepts,thenumberofadvancedmaternalagehasincreasedsignificantly,andtheyarephysicallyandpsychologicallyinferiortowomenoftheappropriateage.Healthcareduringpregnancyisanimportantmeasurethatcaneffectivelypreventandreducecomplicationsduringpregnancy,carryoutbirthdefectscreening,andinterveneearlytoensurethesafetyofmothersandinfants.Itnotonlyallowsthematernaltohaveacorrectunderstandingofpregnancy,butalsogreatlyimprovesthedeliveryexperienceofthematernal.Thisstudywillreviewandcompareanumberofliteraturesforacomparativeanalysis,reviewtheeffectsofhealthcareduringpregnancyontheoutcomesandcomplicationsofpregnancyinadvancedmaternalage,andprovideareferenceforfurtherimprovingtheexperienceofpregnancyandchildbirthinadvancedmaternalage.Keywords:healthcareduringpregnancy;advancedmaternalage;pregnancyoutcomes;complication.3目录1引言...................................................................62相关概念及研究进展.....................................................72.1孕期保健.......................................................72.1.1孕期保健的定义............................................82.1.2基本内容..................................................82.2高龄产妇.......................................................82.1.1高龄产妇的定义............................................82.2.1高龄妊娠人数增加的原因.....................................92.2.2高龄产妇机体与心理的变化...................................92.3妊娠结局.......................................................92.4并发症.........................................................92.5国内外研究进展................................................102.5.1国内研究进展..............................................102.5.2国外研究进展..............................................103孕期保健对妊娠结局和并发症的影响......................................103.1提高对自然分娩的信心，降低剖宫产率............................103.2降低产后出血率及新生儿窒息发生率..............................113.2.1降低产后出血率............................................113.2.2降低新生儿窒息发生率......................................113.3降低妊娠糖尿病发生率，减少巨大儿的发生........................123.3.1降低妊娠糖尿病发生率......................................123.3.2降低巨大儿发生率..........................................123.4降低妊娠期高血压发生率，减少子痫前期的发生....................123.5降低妊娠期肝内胆汁淤积症的发生率，避免引起不良妊娠结局........133.6提高胎儿的存活率，降低了死胎发生率............................133.7降低了早产率，提高婴儿的生存质量..............................144总结..................................................................14致谢....................................................................16参考文献.....................................
