Prevalence of skin disease in a population based sample of adults out of five European countries

Abstract

Background

There is a lack of prevalence data on skin diseases in the general adult population, most studies were carried out in small, national or consecutive clinical samples.

Objectives

To determine the prevalence of common skin disease in the general European population and to additionally assess differences in the characteristics of treatment between countries.

Methods

A random sample consisting out of 12,377 subjects aged 18 to 74 years was drawn from the general population of five European countries (Germany, Italy, The Netherlands, Portugal and Sweden). This was a cross-sectional study and all participants were interviewed with a standardized questionnaire assessing the occurrence of 10 common skin diseases during lifetime, past year and past month. If a skin disease was reported we additionally assessed who performed diagnosis and treatment and if drugs were prescribed.

Results

The most common skin disease was warts (41.3%) followed by acne (19.2%) and contact dermatitis (15.0%). In general females were more often affected by skin diseases compared to males, only in skin cancer the prevalence in males was slightly higher. The prevalence of skin diseases in northern countries (Germany, Netherlands & Sweden) was in general higher than in the southern countries (Italy & Spain). In the Netherlands the treatment of skin diseases was less often performed by a dermatologist compared to the other countries.

Conclusion

The prevalence estimates reported in this study are derived from a representative sample of the general population. Data assessment was performed comprehensively across countries, thus country specific prevalence estimates are comparable.
