Study suggests waist-to-bust ratio, not waist-to-hip ratio, drives female body attractiveness among Japanese men
Japanese men prefer a female body proportion that is exceptionally rare in real life. New research suggests that waist-to-bust ratio, rather than waist-to-hip ratio, drives attractiveness ratings, pointing to media influence over evolutionary biology.
A recent study published in Japanese Psychological Research reveals that Japanese men's perception of female physical attractiveness is influenced more by their waist-to-bust ratio than waist-to-hip ratio. Prof. Tomohiro Suzuki, the lead researcher from Wayo Women’s University, aimed to test if certain body proportions are universally appealing across cultures. He acknowledged that our judgments about physical appearance differ based on era, culture, and fashion trends.
Two key body measurements are the waist-to-hip ratio (lower numbers indicate narrower waists relative to hips) and the waist-to-bust ratio (lower values signify larger busts relative to waists). While a WHR of 0.7 is often deemed the most attractive in Western studies, the Japanese research suggests this might not hold true. The waist-to-hip ratio did not significantly impact Japanese men's ratings of silhouette attractiveness. Instead, a waist-to-bust ratio of 0.7 emerged as the more influential factor.
The study utilized actual body measurement data from Japanese women in their twenties, created three-dimensional simulation models to avoid unnatural distortions seen in previous research, and controlled for body mass index (BMI) within a healthy range of 20 to 22. Participants, aged 20 to 59, rated 16 silhouettes with varying waist-to-hip and waist-to-bust ratios on a six-point scale for aesthetic and sexual attractiveness.
Results indicated that waist-to-hip ratio variations had little effect on attractiveness ratings, contradicting the long-standing belief in Western cultures that a WHR of 0.7 is universally ideal.
