FC03.2 Cumulative incidence of self reported skin disease in hydrotherapists working in swimming pools

Abstract

Objective: To assess the cumulative incidence and characteristics of self reported skin disease in hydrotherapists.Methods: Hydrotherapists, who had completed a hydrotherapy training course answered a questionnaire in reference to newly appeared skin disease. Data were analyzed statistically.Results: 190 subjects presently working as hydrotherapists were studied. Of them 75.8% were female and 24.2% were male. 80% of the hydrotherapists worked up to 10 000 cumulative hours defined by the formula: working hours per weeks × number of weeks per year × years of work in the pool. 85 of the subjects (45%) reported on the development of skin disease for the first time after starting work at the swimming pool. 21 (11.8%) had a preexisting skin disease. The most frequent symptoms included pruritus, burning, stinging, erythematous patches and xerotic skin on the extremities, trunk and folds. A statistically significant relationship between the cumulative working time and the incidence of dermatological pathology compatible with contact dermatitis was found.Conclusions: The incidence of self reported skin diseases, developing for the first time or due to exacerbation of preexisting dermatological conditions, in hydrotherapists working in swimming pools is high. Statistically significant relationship between the cumulative hours of immersion in the pool and the incidence of the dermatological pathology was observed suggesting a dose response relationship between exposure and effect.
