Callus in Adult
An epidemiological study performed at Johns Hopkins University looked at 784 elderly individuals to closely identify such afflictions of the foot. They found that over half had corns or calluses. Thickened toenails, cracks and fissures, maceration, and ulcers or lacerations were more common in men, whereas corns and calluses were more common in women. Women's footwear is often suggested as the reason. Increasing height of heels increases the pressure placed on the balls of the feet. Bunions are reported to have been undetected in Japan before the introduction of Western footwear. Individuals of African descent had a significantly higher prevalence of corns and calluses followed by non-Hispanic white individuals, and finally Puerto Rican individuals. This could be secondary to different rates of chronic conditions such as vascular disease, diabetes (diabetic neuropathy), obesity, and footwear styles.
