Socio-spatial inequalities related to tuberculosis in the city of Itaboraí, Rio de Janeiro

ABSTRACT: Introduction: Tuberculosis remains as a global public health problem and its occurrence and distribution is associated with social inequalities. Itaboraí is among the priority Brazilian municipalities for tuberculosis control. The study aimed to combine social indicators into a composite indicator to measure differences in living conditions of the population in Itaboraí, as well as evidence of health inequalities related to tuberculosis. Methods: An ecological study, with spatial analysis of tuberculosis and its relation to socioeconomic and demographic status of households. Data were obtained from individuals declared in the Mortality Information System (SIM), notified in the Notification of Injury Information System - SINAN or Tuberculosis Special Treatment Information System - SITETB from 2007 to 2013. Results: Evidence indicates association between sociodemographic inequalities and occurrence of tuberculosis in the population. Findings point to a lower percentage of healing and a higher percentage of abandonment and death in areas with high social vulnerability, with a relative risk over twice as high than that found in areas of lower vulnerability. Conclusion: The study showed strong evidence that the influence of unequal sociodemographic conditions have a negative impact on health conditions of the population in Itaboraí.
