Abstract

ABSTRACT Objectives: to identify the trend and factors associated with Tuberculosis-Diabetes Mellitus comorbidity in Imperatriz, Maranhão. Methods: epidemiological temporal-series study, conducted in a Northeastern Brazilian municipality. The population consisted of Tuberculosis cases with Diabetes Mellitus-associated aggravation notified in the Notifiable Diseases Information System (SINAN) between 2009 and 2018. We determined the prevalence and trend of comorbidity using Prais-Winsten regressions and to identify associated factors employed Poisson regression. Results: prevalence ranged from 3.23% in 2014 to 19.51% in 2018, with a mean of 11.5% for the period, showing an increasing trend. Age groups 30 to 59 years and ≥ 60 years, education < 8 years, and clinical form of pulmonary Tuberculosis were risk factors for comorbidity. Conclusions: The increasing trend of comorbidity and its associated factors alert us to the need to improve customer service at all levels of health care.
