| Summary: | Introduction: chronic non-communicable diseases, diabetes mellitus among them, are the epidemics of the 21st century.
Objective: to determine the association between the presence of diabetes mellitus and the development of tuberculosis.
Methods: an observational, analytical-case-control study in 236 patients older than 18 years old (118 cases and 118 controls) was conducted belonging to Trujillo Micro Network Metropolitan of the Health Network in the period 2015-2018. The chi-square independence test was applied, considering the association between variables whether p < 0,05. The risk factor was defined when the odds ratio was greater than 1.
Results: female sex predominated (cases: 50 %; controls: 69,5 %); finding an association between male sex and the presence of tuberculosis (p=0,002; OR=2,278 IC9 %: 1,34-3,88); 51,69 % of the cases reported ages under 45 years and controls 55,93 % were older than 45 years. Literate predominated (cases: 96,61 %; controls: 96,61 %). Patients from urban areas predominated (cases: 88,98 %; controls: 85,59 %). Predominance of patients with body mass index ≤ 30 Kg/m2 was found (cases: 93,22 %; controls: 82,2 %) associated with tuberculosis onset (p=0,008; OR=2,98; IC95%: 1,26-7,03). Type-II diabetes mellitus is associated with the presence of tuberculosis (p<0,001 OR=4,53 IC95%: 2,23-9,19).
Conclusions: on the sample studied of Trujillo Micro Network Metropolitan of the Health Network, diabetes mellitus behaved as a risk factor for the development of tuberculosis.
