Japanese Cedar Pollinosis Impact on Work Productivity, Quality of Life, and Symptoms 2008 vs. 2009

Abstract

Japanese cedar pollinosisJCP , an unfortunately common chronic breathing problem, interferes with cognitive function, impairing work productivity and inducing economic loss. We evaluated JCP impact on work productivity, QOL, and symptoms. Our study, conducted during Japan's peak pollen season, used questionnaires on work productivity and activity impairment allergyspecificWPAIASand Japanese rhino conjunctivitis QOLJRQLQ. The pollen count in 20094067.5/cm 2 was 3 times that in 20081468.4/cm 2. Subjects numbered 227202 employees and 25 studentsin 2008 and 308277 employees and 31 studentsin 2009. Mean workplace absence was 0 9% in 2008 and 1 2% in 2009 and mean work efficiency loss 33% in 2008 and 42% in 2009. Mean classroom absence was 0% in 2008 and 1 5% in 2009 and mean study efficiency loss 33% in 2008 and 48% in 2009, showing a positive correlation between work productivity score, QOL, and symptoms. Work productivity decreased more in 2009 with increased pollen count. With the large economic loss due to pollinosis, both symptom severity and QOL must be improved to increase work productivity.
