Tuberculosis in Northeastern Brasil (2001-2016): trend, clinical profile, and prevalence of risk factors and associated comorbidities

Abstract

OBJECTIVE: To describe the temporal trend, clinical profile, and the prevalence of risk factors and associated comorbidities in new cases of tuberculosis in the Northeast (2001-2016). METHODS: A prevalence study involving all tuberculosis cases registered in Northeast Brasil, 2001-2016. Data were obtained from the National System of Notification of Disorders. For statistical analysis, the inflection point regression model and descriptive statistics were used. RESULTS: 331,245 cases of tuberculosis were reported. The overall incidence rate decreased from 44.84/100,000 inhabitants (2001) to 30.92/100,000 inhabitants (2016), with a decreasing trend (AAPC: -2.3; p<0.001). The profile was characterized by men (73.53%), age 20-59 years (73.56%), pulmonary tuberculosis (86.37%), positive smear microscopy (54.78%). The main risk factors and comorbidities were: AIDS (4.64%), HIV (12.10%), Diabetes mellitus (5.46%), alcohol (11.63%), institutionalized, (4.31%) and deprived of liberty (2.30%). The cure rate was 70.66% and the abandonment rate was 9.11%. CONCLUSIONS: Even with a reduced incidence, tuberculosis represents a real public health problem in the Northeast region. The profile was characterized by a male population, in economically-active age, lung smear-positive pulmonary presentation, and the risk factors and comorbidities of Aids, TB/HIV co-infection, diabetes mellitus, alcohol consumption, institutionalized and deprived of freedom reflect the complexity of the challenges in facing the disease.
