Prevalence of foot eczema and associated occupational and non-occupational factors in patients with hand eczema.

Background: Foot eczema often occurs in combination with hand eczema. However, in contrast to the situation with hand eczema, knowledge about foot eczema is scarce, especially in occupational settings.
Objective: To evaluate the prevalence of foot eczema and associated factors in patients with hand eczema taking part in a tertiary individual prevention programme for occupational skin diseases.
Patients/materials/methods: In a retrospective cohort study, the medical records of 843 patients taking part in the tertiary individual prevention programme were evaluated.
Results: Seven hundred and twenty-three patients (85.8%) suffered from hand eczema. Among these, 201 patients (27.8%) had concomitant foot eczema, mainly atopic foot eczema (60.4%). An occupational irritant component was possible in 38 patients with foot eczema (18.9%). In the majority of patients, the same morphological features were found on the hands and feet (71.1%). The presence of foot eczema was significantly associated with male sex [odds ratio (OR) 1.78, 95% confidence interval (CI) 1.29-2.49], atopic hand eczema (OR 1.60, 95%CI: 1.15-2.22), hyperhidrosis (OR 1.73, 95%CI: 1.33-2.43), and the wearing of safety shoes/boots at work (OR 2.04, 95%CI: 1.46-2.87). Tobacco smoking was associated with foot eczema (OR 1.79, 95%CI: 1.25-2.57), in particular with the vesicular subtype.
Conclusions: Foot eczema is common in patients with hand eczema, and is related to both occupational and non-occupational factors.
