Use of aromatherapy products and increased risk of hand dermatitis in massage therapists.

OBJECTIVES

To determine the 12-month prevalence of hand dermatitis among massage therapists, to investigate a potential association between hand dermatitis and the use of aromatherapy products, and to study potential associations with other known risk factors for hand dermatitis.

DESIGN

Mailed survey.

SETTING

Philadelphia, Pa.

PARTICIPANTS

Members of a national massage therapy organization who live in the greater Philadelphia region.

MAIN OUTCOME MEASURES

Self-reported and symptom-based prevalences of hand dermatitis.

RESULTS

The number of respondents was 350 (57%). The 12-month prevalence of hand dermatitis in subjects was 15% by self-reported criteria and 23% by a symptom-based method. In multivariate analysis, statistically significant independent risk factors for self-reported hand dermatitis included use of aromatherapy products in massage oils, lotions, or creams (odds ratio, 3.27; 95% confidence interval, 1.53-7.02; P =.002) and history of atopic dermatitis (odds ratio, 8.06; 95% confidence interval, 3.39-19.17; P<.001).

CONCLUSIONS

The prevalence of hand dermatitis in massage therapists is high. Significant independent risk factors include use of aromatherapy products in massage oils, creams, or lotions and history of atopic dermatitis.
