[Self-reported prevalence of latex allergy and associated factors in healthcare workers].

BACKGROUND In our country, the prevalence of latex allergy in health personnel has rarely been studied. OBJECTIVE To determine the prevalence and associated factors to self-reported latex allergy in health care workers. METHODS A cross-sectional study was conducted among 1,292 health care workers of a second level hospital. All workers were included and they were required to answer a structured questionnaire aimed at identifying latex allergy, atopic personal and family history, exposure to latex gloves and surgical background. Odds ratio (OR) and 95 % confidence interval (95 % CI) were estimated using regression logistic to investigate factors associated to latex allergy. RESULTS The female to male ratio was 2.4:1. The men age 38.4 ± 11.6 years. The prevalence of latex allergy auto-reported was 9.7 %, with a confidence interval of 95 % (95 % CI) 8.1 %-11.3 %. There was no statistical difference by workplace (p = 0.508). Factors associated with latex allergy included female gender (OR = 1.68; 95 % CI: 1.03-2.73, p = 0.037), personal history of atopy (OR = 4.82; 95 % CI: 3.19-7.26, p < 0.0001), family history of atopic dermatitis (OR = 4.33, 95 % CI: 1.20-4.41) and history of allergy to fruits (OR = 4.33; 95 % CI: 2.62-7.14, p < 0.0001). CONCLUSIONS Up to 10 out to 100 health workers may have latex allergy. The main factors associated with latex allergy in this study were: being a female, personal or familiar atopy and allergy to fruits.
