Recent experimental evidence suggests that stressed males find heavier women more attractive than non-stressed males. The aim of this study is to examine whether these results also appear in actual mating patterns of adults from a national sample.
Regression analysis linking partner weight measures to own measures of childhood stress, as measured by mistreatment. Cross-sectional data from the National Longitudinal Study of Adolescent Health, Romantic Partners Sample is used to measure partner weight, childhood stressful events, and socio-demographic characteristics. Childhood experiences of adult mistreatment are retrospectively collected.
Men who experienced childhood mistreatment are more likely to have obese female partners during young adulthood. The results are strongest for interactions with social services, adult neglect and physical abuse. We also present novel evidence of the opposite association in similarly stressed women whose male partners are more likely to be thin.
These results suggest that preferences for partner characteristics are sensitive to histories of stress and that previously hypothesized patterns occur outside the experimental setting.
最近的实验证据表明，处于压力下的男性比未处于压力下的男性觉得体重较重的女性更具吸引力。本研究的目的是检验这些结果是否也出现在来自全国样本的成年人的实际交配模式中。
通过虐待情况衡量童年压力，将伴侣体重测量值与自身童年压力测量值进行回归分析。来自青少年健康全国纵向研究浪漫伴侣样本的横断面数据用于测量伴侣体重、童年压力事件和社会人口特征。回顾性收集成年人童年时期遭受虐待的经历。
童年遭受虐待的男性在成年早期更有可能拥有肥胖的女性伴侣。与社会服务、成人忽视和身体虐待的互动结果最为显著。我们还提供了新的证据，表明在压力类似的女性中存在相反的关联，她们的男性伴侣更有可能很瘦。
这些结果表明，对伴侣特征的偏好对压力史敏感，并且先前假设的模式在实验环境之外也会出现。
