Prevalence and Severity of Hand Eczema in the Dutch General Population: A Cross-sectional, Questionnaire Study within the Lifelines Cohort Study.

Data on chronic hand eczema and severity of hand eczema in the general population is scarce. In this cross-sectional study, a questionnaire was sent to 135,950 Lifelines Cohort Study participants, in order to investigate the prevalence and severity of hand eczema in the Dutch general population. In total, 57,798 subjects were included. The lifetime prevalence of hand eczema was 15.0% (95% confidence interval 14.7-15.3), the 1-year prevalence 7.3% (95% confidence interval 7.1-7.6), and the self-reported physician-diagnosed prevalence 6.1% (95% confidence interval 5.9-6.3). The 1-year prevalence of chronic hand eczema was 4.7% (95% confidence interval 4.5-4.9). The majority (56.9%) of the subjects with hand eczema had almost clear at worst ever and the prevalence of severe to very severe hand eczema at worst ever in the general population was 1.9% (95% confidence interval 1.8-2.1). Future epidemiological studies in the general population should include data about chronic hand eczema and severity of hand eczema, as this can provide perspective on the burden of hand eczema.
