Characterization of tuberculosis in the Michoacan Local Office, period 2015-2018

Abstract

Introduction: Tuberculosis (TB) is an infectious and curable disease caused by Mycobacterium tuberculosis complex; it affects both men and women at any age.

Objective: To characterize cases of TB presented at the Michoacán Local Office of IMSS (Mexican Institute of Social Security), from 2015 to 2018.

Material and methods: Cross-sectional, observational and analytical study. Cases with a clinical file with complete information and registered in the Epidemiological Surveillance Information System, from 2015 to 2018, at the Michoacán Local Office were included. Descriptive statistics, frequency and association measures were obtained by using XMH and chi‑squared.

Results: 328 cases of TB were found, 56% were male; the most affected age group was the one of 65 years and above with 20%; 28% were housewives; 32% had primary education; 30% were from Lazaro Cardenas jurisdiction; 70% presented pulmonary TB; 88% got cured; 25% were associated with diabetes. The association of pulmonary TB with some risk factors was 1.24 times greater in retired: XMH = 2.02, OR = 2.74, chi‑squared: p = 0.03 (95% CI, 1.03‑7.30); 1.15 times greater in males: XMH = 1.97, OR = 1.61, chi-squared: p = 0.04 (95% CI, 1.00‑2.60), and 1.21 times greater in the age group of 65 years and above: XMH = 2.34, OR = 2. 21, chi-squared: p = 0.01 (95% CI: 1.12‑4.35).

Conclusion: The results of this study are a starting point to prevent, diagnose, control and follow up TB cases at the local office level at IMSS.
