Background:

Objectives:
To measure dissastifaction and acne in 18-year-old male individuals and its associated factors.
Methods:
A questionnaire was applied by trained interviewers to all boys during selection for the military service. Dissatisfaction and acne was evaluated using a self-administered face scale. Facial, prestrernal and dorsal acne were evaluated separately.
Results:
A total of 2,200 adolescents, aged 18 years, were interviewed. Among these, 1,678 had acne on the face and 974 (54.05%) showed some degree of dissatisfaction. Regarding the impact of acne located on the chest, 326 out of 686 adolescents (47.52%) reported dissatisfaction. For acne located on the back, 568 out of 1,103 affected individuals (51.50%) showed dissatisfaction. Facial / dorsal acne and dissatisfaction were statistically associated with lower income, lower education levels and with non-whites. Presternal acne and dissatisfaction were statistically asssociated with lower income and lower education levels.
Conclusion:
This population-based study found a high prevalence of acne on the face, back and chest, with high rates of dissatisfaction.
