How Different Is The Female Neck From Male?

Other conference contribution, 2026

Neck is a commonly injured body region in all crash severities. Impairments from neck injuries are often seen toaffect women more than men in vehicle crashes. In this paper, we study the sex-differences in neck morphologyusing publicly available anthropometry database. The differences in neck circumference and neck lengthbetween men and women are quantified using Bayesian linear regression. Posterior predictive distributions ofthe neck anthropometries for males and females of 5th, 50th, and 95th percentiles sizes were used to evaluatesex-differences. The neck length variations can be attributed to stature. However, the neck circumference wasconsiderably different between men and women. The 95th female neck circumference was seen to be smallerthan 5th male neck circumference. These findings highlight distinct morphological patterns between women andmen, underscoring the need for sex-specific representations in injury assessment.
