Foot Blister Risk Factors in an ROTC Summer Camp Population

Abstract

Data that establish risk factors for foot blister morbidity among ROTC cadets at summer camp are presented. The subjective blister attack rate was 42.1 per 100 cadets. Women had a relative risk of 1.6 that of men (p < 0.001). Cadets with a history of blisters in the 2 years before camp had an increased relative risk of blister formation. Cadets who reported wearing their boots less than 20 hours per week during the 2 weeks immediately before camp had elevated risk. Other factors are examined. These data suggest that the foot must become conditioned to its footwear to prevent blister formation.
