孕期运动干预对孕期体重增长和妊娠结局的影响

目的探讨孕期运动干预对有效控制孕期体重增加和胎儿出生体重、促进顺产的作用。方法对2012-03/12建卡、定期产检、资料完整的孕产妇100例,分为2组,观察组接受孕期运动干预,对照组未进行运动干预,随访孕期体重增加情况及分娩结局。结果观察组孕期体重增加16.14±2.94 kg、剖宫产率24.00%、胎儿出生体重3172.10±312.59g;对照组孕期体重增加18.02±4.49 kg、剖宫产率48.00%、胎儿出生体重3364.60±368.07 g,组间比较P值均小于0.05,差异有统计学意义;孕期运动干预与孕期增加体重、与胎儿出生体重、分娩方式的偏相关系数分别为0.13、0.44、0.14。结论孕期合理运动对控制孕期体重、合理控制胎儿出生体重、促进顺产有明显作用。

Effect of Exercise Intervention on Pregnancy Weight Gain and Delivery Outcomes

Objective To exlpore the effect of exercise intervention in pregnancy period on body weight gain,birth weight of fetus and eutocia. Methods A hundred pregnant women who had registered on Mar. 12,2012,regularly participated antenatal care and with complete information were separated into two groups： the observation group received exercise intervention and the control group received no intervention. Follow- up visit was conducted to collected information of weight gain and delivery outcomes. Results For observation group,the average weight of the pregnant women gained 16. 14 ± 2. 94 kg,the cesarean rate was 24. 00%,the average birth weight of the fetus was 3172. 10 ± 312. 59 g. For control group,the average gain weight was 18. 02 ±4. 49 kg,the cesarean rate was 48. 00% and the birth weight of the fetus was 3364. 60 ± 368. 07 g. The difference between the two groups all had statistical significant（P〈0. 05）. The partial correlation coefficient of exercise intervention with weight gain,birth weight of the fetus and delivery way was respectively 0. 13,0. 44 and 0. 14. Conclusion Reasonable exercise has an evident beneficial effect on body weight control of the pregnant women,birth weight of the fetus as well as eutocia.
