目的 分析营养膳食指导在孕妇中的应用及探讨其对妊娠并发症、母婴结局的影响。方法 选取在我院妇产科就诊妊 娠期单胎产妇110例，随机分为营养组和常规组各55例。常规组采用常规孕期指导方法，营养组在常规组基础上根 据孕妇情况给予营养膳食指导。观察两组孕妇在孕期妊娠并发症情况(妊娠期高血压、妊娠期糖尿病、妊娠期合并 贫血)及母婴结局(阴道分娩、难产、产后出血、早产、低体重儿、巨大儿)。结果 营养组妊娠期高血压、妊娠期糖 尿病、妊娠期合并贫血发生率，均明显低于常规组(P＜0.05)；营养组阴道分娩、难产、产后出血、早产、低体重 儿、巨大儿发生率，均优于常规组(P＜0.05)。结论 在孕妇中采用营养膳食指导，能减少妊娠并发症，增加自然分 娩率，提高新生儿出生质量。

Methods 110 cases of women with singleton pregnancy in department of obstetrics and gynecology of our hospital were selected and randomly divided into nutrition group and routine group, with 55 cases in each group. Routine group was given routine pregnancy guidance method, and nutrition group was given nutritional dietary guidance according to the condition of pregnant woman on the basis of routine group. The pregnancy complications during pregnancy (gestational hypertension, gestational diabetes mellitus, gestational anaemia) and maternal-infant outcomes (vaginal delivery, dystocia, postpartum hemorrhage, premature delivery, low birth weight infant, fetal macrosomia) were observed in the two groups. Results The incidence rates of gestational hypertension, gestational diabetes mellitus and gestational anaemia in nutrition group were significantly lower than those in routine group (P<0.05). The incidence rates of vaginal delivery, dystocia, postpartum hemorrhage, premature delivery, low birth weight infant and fetal macrosomia in nutrition group were better than those in routine group (P<0.05). Conclusion Nutritional dietary guidance in pregnant women can reduce pregnancy complications, increase the rate of natural delivery, and improve the birth quality of newborns.
