[Tuberculosis trend in Madrid region in native and foreign population (2009-2018).]

2020 
OBJECTIVE Tuberculosis is a major public health problem and most cases are concentrated in vulnerable populations. The objective was to describe the incidence rates trend in native and foreign population (2009-2018) in Madrid Region. METHODS Retrospective analysis of cases from the Tuberculosis Regional Registry of cases of Madrid Region 2009-2018. Annual incidence rates were calculated by country of birth (Spain, other), sex and age group ( 64), using the annual January 1st continuous register population. The infection rate trend and the annual percentage change (APC) were calculated, along with the best jointpoint adjustment using Jointpoint regression. RESULTS 7,696 cases were analyzed, 48.2% were foreign-born individuals. Average age in native population was 50 years old (SD: 23.96) and 35 (DS: 36.64) in foreign-born individuals (p<0.001). The overall incidence rate decreased from 17.30 in 2009 to 9.00 per 100,000 in 2018 and was higher in men. Pulmonary tuberculosis reduced from 11.90 to 6.55. Among native population, the incidence of TB fell from 10.29 to 5.24 with an APC of -7.3% (95%IC: -8.9; -5.7) (p<0.05), no jointpoint was identified. Among foreign-born individuals the incidence of tuberculosis declined from 46.54 to 25.49, a joint point was identified in 2013, observing an incidence decrease for the period 2009-2013 and APC of -13.8% (IC95%: -17.5; -10.0). CONCLUSIONS The global incidence rate in this period has decreased by approximately 7% per year. However, this reduction occurred mainly in native population. In foreign-born individuals the incidence decreased by approximately 14% during the 2009-2013 period, after this period there have been no significant incidence changes.
