目的观察孕期补钙预防妊高征疗效。方法将260例20~28周的孕妇随机分为补钙组(130例,服用氨基酸螯合钙)和对照组(130例),分别于服药前测血压、尿蛋白。观察期间每2~4周查一次血压、宫高、腹围并化验尿蛋白。观察缺钙症状发生情况。结果补钙组的临床缺钙症状明显低于对照组,且妊高征(pregnancy-induced hypertension syndrom e,PIH)、胎儿宫内发育迟缓发生率低于对照组(P<0.01)。结论妊娠期补钙有益于降低缺钙症状的发生,降低妊高征、胎儿宫内发育迟缓发生率,提高优生率。
Objective To observe the effect of calcium supplement during pregnancy on preventing pregnancy-induced hypertension syndrome. Methods 260 pregnant women (20-28 weeks) were randomly divided into calcium supplement group (130 patients taking calcium amino acid chelate) and control group (130 patients). Blood pressure and urinary protein were measured before treatment. During the observation period every 2 to 4 weeks to check blood pressure, uterine height, abdominal circumference and urine protein test. Observe the occurrence of calcium deficiency symptoms. Results The clinical symptoms of calcium deficiency in the calcium group were significantly lower than those in the control group. The incidences of pregnancy-induced hypertension (PIH) and intrauterine growth retardation were lower than those in the control group (P <0.01). Conclusion Calcium supplement during pregnancy is beneficial to reduce the occurrence of calcium deficiency symptoms, reduce the incidence of pregnancy-induced hypertension syndrome and intrauterine growth retardation and improve the rate of eugenics.
