A modified life events inventory was presented over a four-month period to 132 consecutive women going into spontaneous labour in Hull and Manchester. Three study groups were identified according to the duration of pregnancy. The levels of psychosocial stress in pregnancy were found to be particularly high in the mothers whose babies were born preterm. Stressful events may precipitate preterm labour in some women. The concept of antenatal care may have to be broadened if the incidence of premature labour and resulting perinatal mortality are to be reduced.
在四个月的时间里，向赫尔和曼彻斯特132名连续自然分娩的女性发放了一份经过修改的生活事件清单。根据孕期时长确定了三个研究组。结果发现，早产婴儿母亲孕期的心理社会压力水平特别高。压力事件可能会促使一些女性早产。如果要降低早产发生率和由此导致的围产期死亡率，产前护理的概念可能需要拓宽。
