The relationships between suicide rates at different ages within male and female birth cohorts in England and Wales are examined. There is a sex difference in the pattern of mean correlations of within-cohort rates for various time intervals, with females showing a significant negative correlation between rates separated by 10-15 years. The full correlation matrix of age-specific rates indicates that this negative mean interval correlation is due to negative correlations between rates at age 35-44 years and rates at other ages. This suggests that the acceleration-deceleration model of suicide may be applicable to female rates, with a reduction in suicide associated with pregnancy and motherhood and a rebound increase in rates thereafter.
对英格兰和威尔士男性及女性出生队列中不同年龄的自杀率之间的关系进行了研究。在不同时间间隔内队列自杀率的平均相关性模式上存在性别差异，女性在间隔10至15年的自杀率之间呈现出显著的负相关。特定年龄自杀率的完整相关矩阵表明，这种负的平均间隔相关性是由于35至44岁年龄段的自杀率与其他年龄段的自杀率之间存在负相关。这表明自杀的加速-减速模型可能适用于女性自杀率，即怀孕和为人母与自杀率降低相关，之后自杀率会反弹上升。
