Women's body morphology and preferences for sexual partners' characteristics☆

Mate preferences are condition dependent (i.e., females in better biological condition might be more demanding with respect to fitness-relevant male traits). Such traits usually indicate male biological quality or ability to secure resources that could be invested in offspring. Here we study female preferences for male resources, commitment, attractiveness, good sense of humor, and sensuality (when seeking both long-term and short-term partners) in relation to women's morphological traits such as height, weight, waist and hip girth, body mass index (BMI), and waist-to-hip ratio (WHR). We show that preferences for resources and attractiveness do indeed depend on women's phenotype. Women with relatively lower WHR and BMI more strongly prefer resources in a potential long-term partner than those with higher WHR and BMI. However, when controlling for age, place of residence, and whether they have had children, it is WHR (but not BMI) that influences female preference for resources and attractiveness. Women with higher WHR (those who, according to many studies, are considered as less attractive) are more prone to prefer physical attractiveness in a potential long-term partner. Furthermore, despite commitment having received the highest score in a long-term context, the preference for this trait in a potential partner was not related to women's body morphology. We suggest evolutionary and proximate explanations for such condition-dependent preferences.
