To systematically explore the risk factors of cutaneous warts and influence factor for the effectiveness of 5-fluorouracil (5-FU). This is a case-control study of 408 cutaneous warts patients and 408 controls of Chinese Han population in southern China. In addition, 244 patients who presented with an initial episode of warts without treatment were treated with intralesional 5-FU. The influence factors of 5-FU therapeutic effects were analyzed. After adjustment, we found age (≤14 years old), lower education attainment, alcohol intake, smoking, less daily sleeping hours, severe psychological stress, hyperhidrosis, living in house or apartment, having cutaneous warts roommates, and sharing personal items with other persons to be risk factors for warts. Importantly, physical fitness played a protective role against warts. Two hundred and twenty-seven patients in 244 (93.03%) were successfully treated with 5-FU. Multivariate analysis indicated that smoking, alcohol intake, severe psychological stress, more than six months' duration of cutaneous warts, lesions on foot and warts diameter ≥5 mm adversely affected the effectiveness of 5-FU. The newly identified risk factors for cutaneous warts and influence factors for efficacy of 5-FU provided clues for warts prevention and treatment of Chinese Han population.
