目的:探讨体质量增长区间对新生儿体质量的影响,为临床围产期的保健研究提供参考依据。方法:采用回顾性研究方法共纳入360例足月单胎儿及其母亲作为观察对象,对母亲孕前体质指数(BMI)、孕期体质量增长状况进行分析,并比较其妊娠结局及对新生儿出生体质量的影响。结果:孕前超重孕妇孕期体质量增长明显低于孕前低体质量及正常体质量孕妇(P<0.05),而孕前低体质量及正常体质量孕妇体质量增长比较差异无统计学意义(P>0.05);新生儿出生体质量及巨大儿出生率与孕前孕妇体质量呈正相关关系,孕前超重孕妇明显高于其他两组,正常体质量孕妇新生儿出生体质量及巨大儿出生率高于低体质量孕妇(P<0.05)。新生儿出生体质量、巨大儿出生率及剖宫产发生率与妊娠期体质量增长呈正相关关系,妊娠期体质量增长过多孕妇新生儿出生体质量、巨大儿出生率及剖宫产发生率明显高于体质量增长适宜及过少孕妇,体质量增长适宜孕妇明显高于体质量增长过少孕妇(P<0.05);妊娠期体质量增长过少孕妇低体质量新生儿出生率明显高于体质量增长适宜及过多孕妇(P<0.05)。孕妇最佳体质量增长区间的Cutoff值为16.0 kg,灵敏度为71.1%,特异度为97.1%。结论:新生儿出生体质量与孕妇孕期体质量增加区间存在密切的相关性,实际生活中孕妇孕期体质量增加区间控制在16.0 kg较为合适。
Objective: To investigate the effect of body mass growth interval on the newborn’s body weight, and to provide a reference for the study of perinatal health care. Methods: A total of 360 full-term single fetuses and their mothers were enrolled in this retrospective study. Their body mass index (BMI) and pregnancy rate were analyzed and their pregnancy outcomes were compared. Quality impact. Results: Before pregnancy, the weight gain of pregnant overweight pregnant women was significantly lower than that of pregnant women with low body weight and normal weight before pregnancy (P <0.05), while there was no significant difference in weight gain between low and normal pregnant women before pregnancy (P> 0.05 ). The birth weight and the birth weight of newborns were positively correlated with the body weight of pregnant women before pregnancy. The overweight pregnant women before pregnancy were significantly higher than those of the other two groups. The birth weight of newborns and the birth rate of macrosomia in normal pregnant women were higher than those of low birth weight pregnant women P <0.05). Neonatal birth weight, macrosomia and caesarean section incidence and pregnancy weight gain was positively correlated with body mass gain during pregnancy too much weight of pregnant women newborn birth weight, macrosomia birth rate and cesarean section was significantly higher Expectant body mass growth and too few pregnant women, body weight growth was significantly higher than pregnant women were less than the increase in body weight pregnant women (P lt; 0.05); pregnancy weight gain too low birth weight pregnant women with low birth weight was significantly higher than the birth weight growth Suitable and too much pregnant women (P <0.05). The Cutoff value of pregnant women with the best body weight gain interval was 16.0 kg, with a sensitivity of 71.1% and a specificity of 97.1%. Conclusion: There is a close correlation between the birth weight of newborns and body mass gain during pregnancy, and it is more appropriate to control the weight gain during pregnancy in pregnant women at 16.0 kg.
