A reported association of social status of parents with infants' sex ratio at birth and of psychological stress (score on Beck Depression Inventory) with sex ratio were not supported by our analysis, but the possibility of an association between scores on the Rosenberg Self-esteem scale and sex ratio at birth for a sample of 385 pregnant women showed that women who have given birth to boys scored lower on self-esteem during pregnancy than those who have given birth to girls. Some explanations are reviewed to discuss this unforeseen association.
父母的社会地位与婴儿出生时的性别比之间以及心理压力（贝克抑郁量表得分）与性别比之间的报道关联未得到我们分析结果的支持，但对385名孕妇样本进行的罗森伯格自尊量表得分与出生时性别比之间关联的可能性分析表明，生男孩的女性在孕期的自尊得分低于生女孩的女性。本文回顾了一些解释来探讨这一意外关联。
