目的 :探讨孕妇纤维素食用量与妊高征危险性的关系。方法 :将患妊高征的妇女与正常妊娠的妇女按 1∶ 1配对 ,对两者膳食中纤维素重量之差值用序贯 t检验作评价。结果 :当试验至第 2 2对时 ,试验线触及序贯试验图的上界 U,即正常妊娠妇女食纤维素较妊高征的妇女多。结论 :增加孕妇膳食中纤维素含量对控制妊高征有益 Objective: To investigate the relationship between the consumption of fiber in pregnant women and the risk of pregnancy-induced hypertension. METHODS: Women with PIH were paired 1: 1 for women with normal pregnancy, and the difference in weight of dietary fiber between the two was evaluated by sequential t-test. Results: When the test to the 22nd pair, the test line touches the upper bound of the sequential test chart U, that is, women with normal dietary fiber than normal pregnancy-induced hypertension more women. CONCLUSIONS: Increasing the dietary fiber content of pregnant women is beneficial for controlling PIH
