Associations between lifestyle factors and hand eczema severity: are tobacco smoking, obesity and stress significantly linked to eczema severity?

Abstract

Background: It has been suggested that lifestyle factors such as smoking, overweight and stress may influence the prevalence and severity of hand eczema.

Objectives: To investigate the association between lifestyle factors and hand eczema severity in a cohort of patients with work-related hand eczema.

Methods: Individuals with work-related hand eczema notified in the period between June 2012 and November 2013 were included in this questionnaire-based cross-sectional study. Participants responded to a questionnaire including questions on lifestyle factors, as well as a photographic guide for assessment of severity of hand eczema and questions on quality of life.

Results: A total of 773 individuals (546 women and 227 men) responded to the questionnaire and were included in the study. A strong association was found between tobacco smoking and hand eczema severity (p = 0.003), whereas no significant association was found for body weight and stress. Other factors linked to severe eczema were male sex and older age (p = 0.04 and p = 0.01, respectively), and wet work (p = 0.08).

Conclusion: The data from the present study strongly support an association between smoking and hand eczema severity. However, owing to the cross-sectional design of the study, no conclusion on causation can be drawn.
