目的 :研究孕妇孕期体重增加与血压变化关系。方法 :测量 5 10名足月妊娠妇女孕期体重增加与血压升高情况 ,并对其之间的关系进行分析。结果 :孕期体重增加范围 5 5～ 2 9kg ,平均 16 2kg。血压较基础压升高≥ 3 0 15mmHg 15 0人 ( 2 9 4% ) ,包括临床诊断妊高征 (血压 >14 0 90mmHg)者 3 6人 ( 7 1% ) ,其中轻度妊高征 2 9人 ( 80 5 % ) ,重度妊高征 7人 ( 19 4% ) ,其余 114人( 76 0 % )血压均在正常范围但较基础压升高≥ 3 0 15mmHg( 2 1人 )或收缩压升高≥ 3 0mmHg( 2 4人 )或舒张压升高≥ 15mmHg( 67人 )。孕期体重增加 >2 0kg组血压升高、妊高征的发生率均较 <2 0kg组明显升高 ( P <0 0 1)。孕前肥胖孕妇的血压升高及妊高征发生率较非肥胖者升高 (P <0 0 5 )。结论 :孕妇体重增加过多容易发生妊高征 ,孕前肥胖者发生率更高 ,所以孕期体重增加以孕前肥胖者小于 10kg ,孕前非肥胖者小于 2 0kg为宜。
Objective: To study the relationship between pregnant women weight gain and blood pressure during pregnancy. METHODS: We measured weight gain and blood pressure during pregnancy in 510 pregnant women, and analyzed the relationship between them. Results: The weight gain during pregnancy ranged from 5 5 to 29 kg with an average of 16 2 kg. Blood pressure was ≥30 15 mmHg 15 0 (294%), including 36 (71%) clinically diagnosed PIH (BP> 14 0 90 mmHg), with mild PIH 2 9 (80.5%) and severe PIH (7 4%), the remaining 114 (76.0%) were in the normal range but higher than the basal pressure ≥3015mmHg (21) or contracted Pressure elevation ≥ 30 mmHg (24) or diastolic blood pressure ≥ 15 mmHg (67). During pregnancy, weight gain> 20kg increased blood pressure, the incidence of pregnancy-induced hypertension were significantly higher than <20kg group (P <0.01). Pregnant women with obesity before pregnancy increased blood pressure and pregnancy-induced hypertension than non-obese were higher (P <0 05). Conclusion: Excessive weight gain in pregnant women is prone to PIH. The incidence of obesity before pregnancy is higher. Therefore, weight gain during pregnancy should be less than 10kg for pre-pregnancy obesity and less than 20kg for non-obese pre-pregnancy.
