Demographic and clinical features and subsectoral differences in occupational contact allergens in clothing manufacturing workers.

BACKGROUND

Epidemiologic data on the occurrence of contact dermatitis (CD) and the contact allergens involved in clothing manufacturing and its subsectors are scarce. This study aimed to determine the extent of occupational contact allergy and differences between work subsectors in clothing employees with CD.

METHODS

A cross-sectional study was conducted with 272 clothing employees, who complained of CD and were diagnosed with occupational allergic contact dermatitis (OACD). Participants worked in accessory, dyeing, sewing, cutting, knitting, packing, cleaning, and ironing subsectors. Data on demographics, working-subsector, working-duration, and lesion-duration were collected, and participants were examined and patch tested.

RESULTS

Participants included 173 females and 99 males. Dyeing workers were most frequently diagnosed with OACD, whereas cutting workers were least. Lesions were mostly located on the hands only. The most frequently detected allergens were nickel sulfate in accessory work; disperse blue-106 in dyeing, sewing, cutting, and knitting; cobalt chloride in packing; p-phenylenediamine in cleaning; and budesonide in ironing.

CONCLUSIONS

Contact allergens show significant differences in frequency by work subsectors in clothing employees. Careful monitoring of workers for excessive exposures and for early signs of CD is warranted.
