What we do
In the last years there has been a steady increase of subjects, especially women, over 25 years old, affected by acne. Several studies have estimated a significant increase in the prevalence of acne in women aged between 25 and 40 years.
From a clinical point of view two types of acne in adulthood have been observed: persistent acne, a more frequent condition that begins in adolescence and continues into adulthood, and acne in early or late post-puberty, which occurs after the age of 25.
Causes and factors that may promote the worsening of acne in adult women are not yet fully identified: internal factors (hormones, use of progestins, genetic predisposition) and external or environmental factors (use of cosmetics, stress, smoke) are recognized.
Centro Studi GISED proposed an observational case-control study: all consecutive patients aged ≥25 years referring to dermatology outpatient of participating Center and with a diagnosis of acne (any grade) by a dermatologist at the time of the visit, were considered as cases; all consecutive patients aged ≥25 years referring to dermatology outpatient for conditions different from acne and without a diagnosis of acne by a dermatologist at the time of the visit, were considered as controls.
Demographics and medical data, clinical history, dietary habits and use of drugs were collected through a questionnaire, on an overall sample of 248 cases e 270 controls.
Data will be analyzed by usual methods of case-control studies in order to identify risk factors (individual and environmental) linked to the onset and severity of acne in adult women.
