Infant and maternal mortality rates are among the highest in the world in low and middle-income countries where postpartum depression impacts at least one in five women. Currently, there is a dearth of data on maternal mood and infant health outcomes in small-scale non-industrial populations from such countries, particularly during the postnatal period. Here, we present the first investigation of postpartum maternal mood among a foraging population, the Hadza of Tanzania. We administered the Edinburgh Postnatal Depression Scale (EPDS) to twenty-three women, all with infants under the age of 12 months. Semi-structured interviews on happiness and unhappiness during the post-partum period served as a validity cross-check for the EPDS. The combined results of the EPDS surveys and the interview responses suggest that a high proportion of Hadza women experience significant mood disturbances following birth and that postpartum unhappiness is associated with self-reports of pain, anxiety, and disturbed sleep patterns. These findings suggest that many of the mothers in our sample are experiencing post-partum unhappiness at levels similar to or higher than those reported for low to middle income countries in general, including Tanzania. These data are critical for improving our understanding of the etiologies of postpartum mood disturbances cross-culturally.

坦桑尼亚Hadza觅食者的产后产妇情绪：一种混合方法。

在低产和中等收入国家，婴儿和产妇的死亡率是世界上最高的，产后抑郁症至少影响五分之一的妇女。目前，在这些国家的小规模非工业人群中，尤其是在产后时期，缺乏关于母亲情绪和婴儿健康结局的数据。在这里，我们对觅食人群坦桑尼亚的Hadza进行了产后产妇情绪的首次调查。我们对23名年龄在12个月以下的婴儿的妇女进行了爱丁堡产后抑郁量表（EPDS）。产后时期对幸福感和不幸福感的半结构式访谈是对EPDS有效性的交叉检查。EPDS调查和访谈答复的综合结果表明，Hadza妇女中有很大比例的人在出生后会出现严重的情绪障碍，而产后不满与疼痛，焦虑和睡眠方式的自我报告有关。这些发现表明，我们样本中的许多母亲正在经历产后不适，其水平与包括坦桑尼亚在内的中低收入国家的报告水平相近或更高。这些数据对于增进我们对跨文化产后情绪障碍病因学的理解至关重要。这些发现表明，我们样本中的许多母亲正在经历产后不适，其水平与包括坦桑尼亚在内的中低收入国家的报告水平相近或更高。这些数据对于增进我们对跨文化产后情绪障碍病因学的理解至关重要。这些发现表明，我们样本中的许多母亲正在经历产后不适，其水平与包括坦桑尼亚在内的中低收入国家的报告水平相近或更高。这些数据对于增进我们对跨文化产后情绪障碍病因学的理解至关重要。
