Results: Most (78%) women reported some degree of heartburn. Symptom severity was unrelated to fetal sex and maternal characteristics including parity, age, or weight. The simple linear relationship between heartburn severity and hair volume was significant r(s)(62) = 0.40, p < 0.001. Categorical analysis by severity score and hair ranking revealed a similar association (chi(2)= 23.93, p < 0.05). Most (23/28) women who reported moderate or severe heartburn gave birth to babies with average or above average amounts of hair, and conversely, most (10/12) women reporting no heartburn had babies with less than average or no hair.

Conclusions: Contrary to expectations, it appears that an association between heartburn severity during pregnancy and newborn hair does exist. We propose a shared biologic mechanism involving a dual role of pregnancy hormones in both the relaxation of the lower esophageal sphincter and the modulation of fetal hair growth.
