Methods (1) • The data of the Finnish ROD and the Finnish Population Census Registry were linked by the unique personal identification code assigned to everyone residing in Finland.
Methods (2) • The analyses were restricted to all wage earners and agricultural workers aged 25-64 years. • The occupation of the study subjects was obtained from the 1985 population census. • Follow-up time: beginning of 1986 to end of 1991. • Subjects excluded from the study population: those • having contracted an occupational dermatosis • turned 65 years of age • deceased
Methods (3) • Age-standardized rate ratio (SRR) was calculated with reference to the total study population.
General findings OCD Women Total Men ICD ACD CU/PCD
The highest SRR of ICD (95% confidence interval) (N=2237, number of cases >10)
Most common irritants in occupations with the highest risk of ICD • Organic solvents • Detergents • Oils and lubricants, including metal-working fluids • Cement-based products • Foodstuffs • Plastic chemicals
The highest SRR of ACD (95% confidence interval) (N=2020, number of cases >10) ’
Most common allergens in occupations with the highest risk of ACD • Rubber chemicals • Plastic chemicals • Metals and metal compounds • Formaldehyde and other antimicrobials
The highest SRR of CU/PCD (95% confidence interval) (N=412, number of cases >5)
Most common allergens in occupations with the highest risk of CU/PCD • Flours • Cow dander • NRL proteins • Foodstuffs
Conclusion • The study gave new information on the relative risk to develop an occupational skin disease in various occupations. • The differences in the risk of developing an occupational disease were very great. • Dental care workers had the highest risk of allergic contact dermatitis.
