Abstract
The aim was to analyze the prevalence of latent tuberculosis infection and associated risk factors in healthcare personnel at the Hospital de Tortosa Verge de la Cinta (Tarragona, Spain). This was a cross-sectional study of 398 workers at this hospital who underwent tuberculin skin testing for latent tuberculosis infection (LTBI) between 2001 and 2012.We also analyzed the relationship between LTBI and age, sex, job and work area according to their risk of exposure to tuberculosis(high, low, uncertain). The total prevalence of LTBI in our sample was 11.1% (95%CI 8.3%-14.5%). LBTI was associated with age and work area. Multivariate analysis showed that the risk of LTBI increased by 6.4% per 1 year increase in age. The prevalence of LTBI in this population approximates that of the general population in Spain.
