Abstract

Background: Many risk factors such as atopic dermatitis (AD) have shown to associate with hand eczema (HE). However, studies concerning other atopic diseases, parental or longitudinal risk factors of HE are scarce.

Objectives: To examine the association between HE and atopic diseases, parental factors, environmental factors (keeping animals, exposure to moulds) and lifestyle factors (obesity, tobacco smoking, alcohol consumption and physical activity) at population level.

Methods: Subjects belonging to the Northern Finland Birth Cohort 1966 Study (NFBC1966) (n = 6830) answered a comprehensive health questionnaire. The data was completed with parental information.

Results: HE was reported in 900 (13.3%) individuals. All atopic diseases, parental allergy, female gender and obesity increased the risk of HE whereas physical activity decreased the risk of HE. A statistically significant association was not found between HE and tobacco smoking or alcohol consumption.

Conclusions: All atopic diseases, not only AD, seem to have influence on the presence of HE. In addition, parental and environmental factors associated with HE.
