目的探讨孕妇身体活动状况与围产期结局的相关性。方法 2012年11月-2013年12月追踪152名孕妇整个孕期身体活动状况及围产期结局。对孕期身体活动状况与围产期结局的相关性进行分析。结果 101名(66.45%)孕妇体重增加超标,孕期平均体重增加为(18.79±5.06)kg,新生儿平均体重为(3.43±0.40)kg;孕早期、孕中后期运动达标组孕妇孕期体重增加超标率、孕期体重增加值、50 g糖耐量筛查的血糖值均显著低于运动不达标组(P<0.01),孕中后期运动达标组新生儿体重显著低于运动不达标组(P<0.05);孕早期、孕中后期能耗值与孕期体重增加值、50 g糖耐量筛查的血糖值均呈负相关(P<0.05),孕中后期能耗值与新生儿体重呈负相关(P<0.05)。结论无论孕早期还是孕中后期的身体活动,尤其运动/锻炼的增加,有利于孕妇血糖及孕期体重的控制;同时,孕中后期的运动有利于控制新生儿体重。
Objective To investigate the correlation between physical activity and perinatal outcome in pregnant women. Methods From November 2012 to December 2013, 152 pregnant women were followed up for physical activity during the whole pregnancy and perinatal outcome. The correlation between prenatal physical activity and perinatal outcome was analyzed. Results The weight gain of 101 pregnant women (66.45%) exceeded the standard. The average weight gain during pregnancy was (18.79 ± 5.06) kg and the average weight of newborn infants was (3.43 ± 0.40) kg. Pregnant women with exercise standard in early pregnancy and middle- (P <0.01). The weight of newborn infants who reached the goal of exercise in the second trimester was significantly lower than that of the control group (P <0.05) ). The energy consumption during the first trimester and the second trimester were negatively correlated with the body weight gain during pregnancy and the glucose level at 50 g glucose tolerance test (P <0.05), and negatively correlated with energy expenditure at the second trimester P <0.05). Conclusion Both physical activity in early pregnancy and second trimester, especially exercise / exercise, is beneficial to the control of blood glucose in pregnant women and weight control during pregnancy. Meanwhile, exercise during the second trimester is conducive to controlling newborn weight.
