The frequency of fragrance allergy in patch-tested patients increases with their age.
BRITISH JOURNAL OF DERMATOLOGY(2003)
摘要
Background The most likely age of sensitization to fragrance chemicals is unknown. Objectives To investigate the frequency of allergy to the 8% fragrance mix (FM) in each decade of life in patients undergoing patch testing for the investigation of skin symptoms. Methods Patients (n = 23 846; 14 104 female and 9742 male) underwent patch testing to a standard series between 1 January 1984 and 31 December 1998. All data were recorded on a computerized database. Results We found that 8.4% of females and 6.4% of males were allergic to the FM. The frequency of fragrance allergy was low in the first two decades of life (2.5-3.4%). It gradually increased in females after the age of 20 years to peak in the 60s at 14.4% of those tested, with a decline to 11.6% in the 80s. The prevalence in males rose more slowly and peaked at 13.7% in the 70s, declining to 10.8% in the 80s. The youngest patients sensitized were aged 2 years. Conclusions These findings support the hypothesis that allergy to fragrance results from a combination of repeated environmental exposure and age-related susceptibility factors.
