Although numerous studies have documented changes in the behavior of nonhuman primate females around the time of ovulation, very little attention has been paid to behavior changes around the time of menstruation. Yet such information is obviously relevant to under standing the origins and etiology of the adverse mood and behavior changes experienced premenstrually by many women. Analysis of data obtained during 115 hours of observation on 13 female Amboseli (Kenya) baboons (Papio cynocephalus) during 24 menstrual periods showed that prior to and during the time of menstrual onset, these individuals exhibited distinct changes in their activity budgets, nearest-neighbor distances, and patterns of social interaction. Furthermore, in comparison to females around the time of ovulation, perimenstrual females showed increased rates of agonistic interaction and decreased (but nonzero) rates of sexual interaction with adult males. These premenstrual and perimenstrual behavior changes among female yellow baboons thus show some intriguing similarities to several commonly reported behavioral symptoms of premenstrual syndrome (PMS) in women.
虽然许多研究记录了非人类灵长类雌性动物在排卵前后行为的变化，但很少有人关注月经期间的行为变化。然而，这些信息对于理解许多女性在经前经历的不良情绪和行为变化的起源和病因显然是相关的。对 13 只在肯尼亚安博塞利的雌性狒狒（Papio cynocephalus）在 24 个月经周期内 115 小时观察中获得的数据进行分析表明，在月经开始之前和期间，这些个体的活动预算、最近邻距离和社会互动模式都发生了明显的变化。此外，与排卵期间的雌性相比，经期前后的雌性与成年雄性的争斗互动频率增加，而性互动频率（但非零）降低。因此，黄狒狒的这些经前和经期行为变化与女性经前综合征（PMS）的几种常见报告行为症状有一些有趣的相似之处。
