Smoking and dietary factors associated with moderate-to-severe acne in French adolescents and young adults: results of a survey using a representative sample.

Background: Dietary factors and smoking play a role in acne.

Methods: CSA Santé conducted a survey in France in 2012. Each individual answered a questionnaire to report acne, with associated epidemiological variables.

Consequences of acne on stress, fatigue, sleep disorders and sexual activity: a population-based study.

Acne is a common disease among young people, which could have a serious impact on quality of life. Based on a survey using the quotas method on a large sample of the French population, we studied the impact of acne on feelings of stress, fatigue upon waking, sleep disorders and sexual activity. We did not establish any relationship to sleep disorders, but clearly ascertained that people with acne (n = 1,375) feel more stressed and have less sexual intercourse.
