Prevalence and quality of life of facial acne: a cross-sectional study in high school students in Poland

Introduction
Acne is a frequent chronic inflammatory disease, which affects most commonly adolescents. It might have a negative effect on patients’ well-being.

Aim
To appraise the prevalence of facial acne among adolescents and to assess how acne of different clinical severity influences quality of life in this age group.

Material and methods
This cross-sectional study was conducted on a representative sample of individuals aged 15–19 years in high schools in Poland. A total of 730 students were included in the final analysis. Standardized photographs according to the Investigator’s Global Assessment (IGA) were used for self-assessment of both the presence and severity of facial acne. The Dermatology Life Quality Index (DLQI) was employed to evaluate subjects’ quality of life (QoL) impairment.

Results
Facial acne was found in 547 (74.9%) respondents with no significant difference in acne prevalence among females (75.1%) and males (74.6%). The vast majority of acne individuals (90.9%) suffered from minimal and mild acne, moderate acne was reported by 7.3% and severe one by 1.8% of acne students. Acne had a small effect on QoL (DLQI mean score of 2.8 ±3.6 points); females had significantly more decreased QoL than males (3.17 ±3.74 and 1.76 ±2.69 points, respectively). QoL impairment positively correlated with the clinical severity of facial acne.

Conclusions
Facial acne is a common health problem in adolescents. Although it is not very severe in the majority of subjects it significantly decreases their QoL. Therefore, acne should be treated as a serious skin condition requiring a holistic approach to the patients.
