Adaptive significance of female physical attractiveness: Role of waist-to-hip ratio.

TLDR

Waist‑to‑hip ratio (WHR) is linked to youthfulness, reproductive status, long‑term health risk, and is perceived by men as a marker of attractiveness, indicating its importance for physical appeal and reproductive potential. The study proposes a hypothesis explaining how WHR influences female attractiveness and its role in mate selection. Across three studies, WHR has shifted only slightly in popular beauty icons, yet men of all ages consistently rate lower WHR as more attractive, healthier, and more reproductively valuable.

Abstract

Evidence is presented showing that body fat distribution as measured by waist-to-hip ratio (WHR) is correlated with youthfulness, reproductive endocrinologic status, and long-term health risk in women. Three studies show that men judge women with low WHR as attractive. Study 1 documents that minor changes in WHRs of Miss America winners and Playboy playmates have occurred over the past 30-60 years. Study 2 shows that college-age men find female figures with low WHR more attractive, healthier, and of greater reproductive value than figures with a higher WHR. In Study 3, 25- to 85-year-old men were found to prefer female figures with lower WHR and assign them higher ratings of attractiveness and reproductive potential. It is suggested that WHR represents an important bodily feature associated with physical attractiveness as well as with health and reproductive potential. A hypothesis is proposed to explain how WHR influences female attractiveness and its role in mate selection.
