Three studies on the relationship between life stresses and premature labor were conducted. The first was a retrospective comparison of life events between a group of women who had had premature labor and a group of controls. It was carried out between 3 and 6 months after the premature delivery to neutralize possible effects of time closeness to the traumatic event and of mothers' anxiety for the babies' condition. Results showed no difference between groups. In a second, prospective study, women who afterwards developed premature contractions were found to have a slightly higher frequency of life events. A third study investigated effects of the stress of the Yom Kippur War upon incidence of premature deliveries. It was found that during the war and immediately after it, the frequency of premature deliveries was lower than a year later. Results showed that most research conducted in this field has led to doubtful conclusions. The need for prospective studies and for investigations of the effects of real-life stresses is underlined.
开展了三项关于生活压力与早产之间关系的研究。第一项研究是对一组早产女性和一组对照组的生活事件进行回顾性比较。该研究在早产分娩后3至6个月进行，以消除时间上接近创伤性事件以及母亲对婴儿状况的焦虑可能产生的影响。结果显示两组之间没有差异。在第二项前瞻性研究中，发现后来出现早产宫缩的女性生活事件发生频率略高。第三项研究调查了赎罪日战争的压力对早产发生率的影响。结果发现，在战争期间及战争刚结束后，早产频率低于一年后。结果表明，该领域进行的大多数研究都得出了可疑的结论。强调了进行前瞻性研究以及调查现实生活压力影响的必要性。
