Previous studies have demonstrated that men prefer women’s voices with relatively high pitch to those with low pitch, suggesting that men may use voice pitch as a cue of women’s mate quality. However, evidence that voice pitch is a cue to women’s long-term health is equivocal. Here we present evidence that women’s average speaking voice pitch is negatively correlated with a health risk index derived from principle component analysis of various body measurements that are known to predict long-term health outcomes in women (weight, body mass index, percentage body fat, waist and hip circumference, and waist-hip ratio). Our results suggest that voice pitch is a cue to women’s long-term health, supporting mate-choice accounts of men’s preferences for raised pitch in women’s voices.
