Fact-Checking the Leeds Hip Study: Do Wider Hips Truly Influence Sexual Behavior?
By James H. Sterling
Did the University of Leeds study prove that hip width causes casual sex?
No. The study established a statistical correlation within a modest sample of 148 British university students. Correlation does not demonstrate biological causation, and the study did not measure hormone levels or account for social conditioning.
Does a wide pelvis guarantee an easier childbirth?
Not necessarily. The inter-crestal measurement captures the outer edges of the pelvic bones. Clinical pelvimetry shows that the internal pelvic inlet and mid-pelvic cavity dimensions govern actual delivery ease, and these internal spaces do not always correlate with outer skeletal breadth.
What is the difference between pelvic width and waist-to-hip ratio?
Pelvic width measures the rigid skeletal bone distance between the iliac crests. Waist-to-hip ratio measures soft tissue circumference, determined primarily by muscle structure and estrogen-driven fat distribution across the waist and hips.
Why did media outlets emphasize the "confidence" explanation?
Media coverage focused heavily on Hendrie’s secondary hypothesis: that women with wide hips possessed an unconscious, evolutionarily driven confidence that protected them from fears of birth complications. This made for viral news coverage, but subsequent anthropological reviews found little hard evidence to support unconscious skeletal self-awareness.
