Background:

Prevalence of latex allergy in medical students is not known.

Objective:

To determine the prevalence of self-reported latex allergy and associated factors in medical students.

Methods:

Cross-sectional, analytical study of students with or without self-reported latex allergy. By means of a structured questionnaire, past personal and family history of allergic disease, time and frequency of exposure to latex gloves and symptoms after exposure to products or foods associated with latex allergy were inquired. Logistic regression models were carried out.

Results:

Out of 854 subjects, 431 (50.5%) were females. Median age was 21 years. Overall prevalence of latex allergy was 4.3% (95% CI = 3.1 to 5.9). Associated risk factors were age (OR = 1.37; 95% CI = 1.05 to 1.79), personal history of atopic dermatitis (OR = 7.32; 95% CI = 3.14 to 17.08), use of gloves ≥ 15/week (OR = 2.59; 95% CI = 1.17 to 5.76), use of latex products (OR = 5.76; 95% CI = 2.15 to 15.49) and fruit allergy (OR = 3.24; 95% CI = 1.27 t o8.27).

Conclusion:

Four out of a hundred students reported latex allergy. Age, personal history of atopic dermatitis, higher frequency of exposure to latex gloves and history of fruit allergy were risk factors for self-report latex allergy.
