目的：对孕妇进行孕期营养指导及体质量控制，探究其对妊娠结局的影响。方法：将2011 年2 月-2014年2 月期间我院收治的孕产妇150 例纳入本次研究，所有研究对象随机均衡分为研究组和对照组，每组各75 例。对照组孕产妇仅行常规妇科检查，研究组孕产妇在医护人员指导下行孕期营养指导和体质量控制，比较两组分娩方式，妊娠过程状况及围产儿情况。结果：研究组剖宫产率为17.33%低于对照组的57.33%，组间差异存在统计学意义(P<0.05)。研究组贫血、羊水过少、产后出血率均低于对照组，差异有统计学意义(P<0.05)。研究组胎龄及巨大儿及胎儿窘迫率均低于对照组，差异有统计学意义(P<0.05)。结论：孕产妇在孕期进行营养膳食指导，控制体质量在合理范围内，可以改善孕妇妊娠结局，降低妊娠过程中并发症发病率，提高围产儿状况，保证孕妇和婴儿健康。

英文摘要:

Objective:To conduct the nutrition guidance and body mass control for pregnant women during pregnancy, and explore its influence on pregnancy outcome.Methods:A total of 150 pregnant and parturient women, who were admitted to Yulin Red Cross Hospital from February 2011 to February 2014, were selected and randomly divided into research group (n=75) and control group (n=75). The control group was given regular gynecological examination, while the research group was given the nutrition guidance and body mass control under the guidance of medical staff. Then the delivery mode, pregnant women status during pregnancy and perinatal fetus conditions in the two groups were compared.Results:Cesarean delivery rate (17.33%) in the research group was significantly lower than that (57.33%) of the control group, the difference was statistically significant (P<0.05). The rates of anemia, less amniotic fluid and postpartum hemorrhage in the research group were significantly lower than those in the control group, the differences were statistically significant (P<0.05). The gestational age, macrosomia and fetal distress rate in the research group were significantly lower than those in the control group, the differences were statistically significant (P<0.05).Conclusion:Conducting the nutrition guidance and controlling body mass in a reasonable range for pregnant and parturient women during pregnancy can improve the pregnancy outcomes, decrease the incidence of complications during pregnancy and improve the perinatal fetus conditions, which can guarantee the health of pregnant women and infants.
