孕期合理营养对胎儿出生体重及剖宫产率的影响

目的探讨孕期合理营养对胎儿出生体重及剖宫产率的影响,为孕期合理膳食提供指导,尽量降低剖宫产率。方法将2010年2月～2011年3月在我院产科门诊孕3个月建产检卡并确定在我院分娩孕妇243例,将自愿或者有能力参加孕期膳食营养指导152例孕妇设为观察组,给予饮食结构分析指导;不愿或者无能力参加孕期膳食营养指导正常饮食孕妇91例设为对照组,孕期常规饮食。结果观察组新生儿的出生体重平均3 158.2 g,对照组3 458.7 g,两组比较有显著性差异(p<0.05),两组之间出生胎龄比较无显著性差异(p>0.05);观察组孕妇正常阴道分娩者121例(79.61%),剖宫产者31例(20.39%),巨大儿12例(7.89%),对照组正常阴道分娩者54例(59.34%),剖宫产37例(40.66%),巨大儿15例(16.48%),两组间在阴道分娩、剖宫产率、巨大儿发生率方面比较均存在显著性差异(p<0.05)。结论孕期对孕妇进行合理饮食指导,有利于合理膳食的摄入,有效的控制胎儿体重增长,减少巨大儿发生和降低剖宫产率,达到理想的分娩结局,保障母婴健康。
