Abstract
INTRODUCTION
This study sought to study the epidemiological characteristics of the extrapulmonary tuberculosis (EPTB) in relation to pulmonary tuberculosis (PTB) from 2007 to 2012 in Spain, and plot its trend across the same period.

METHODS
We conducted an analytical cross-sectional study in which the following variables were analysed: age; sex; disease site; history of antituberculosis treatment; country of birth; presence of HIV infection; and culture results. Age-related differences were ascertained using the test of comparison of proportions, and crude and adjusted ORs were calculated using linear regression models.

RESULTS
Of the total of 44,050 cases of tuberculosis reported in the period 2007-2012 and included in the study, 31,508 (71.53%) were pulmonary tuberculosis and 12,542 (28.47%) were EPTB. EPTB rates decreased across all age groups. The main EPTB risk factor was presence of HIV infection (OR 1.39). Persons aged under 65 years had a lower risk of EPTB.

CONCLUSIONS
Although persons aged over 65 years displayed the highest incidence, there was nevertheless a downward trend across all age groups. Whereas children showed a significant decrease in tuberculous meningitis, this was not so for all extrapulmonary forms. EPTB rates among persons born outside Spain were much higher than those among the Spanish population.
