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.

Introducción: la tuberculosis (TB) es una enfermedad infectocontagiosa y curable que es producida por el complejo Mycobacterium tuberculosis; afecta tanto a hombres como a mujeres de cualquier edad.

Objetivo: caracterizar casos de TB presentados en la Delegación Michoacán del Instituto Mexicano del Seguro Social (IMSS), en el periodo 2015 2018.

Material y métodos: estudio transversal, observacional y analítico. Se incluyeron casos con expediente clínico con información completa, registrados en el Sistema de Información de Vigilancia Epidemiológica, del 2015 al 2018, en la Delegación Michoacán. Se obtuvo estadística descriptiva, medidas de frecuencia y asociación utilizando XMH y chi cuadrada.

Resultados: se encontraron 328 casos de TB, 56% eran hombres; el grupo más afectado fue el de 65 años o más con 20%; 28% fueron amas de casa; 32% tenía la primaria; 30% eran de la jurisdicción Lázaro Cárdenas; 70% tuvo TB pulmonar; 88% se curó; 25% estaban asociados a diabetes; la asociación a TB pulmonar con algunos factores de riesgo fue 1.24 veces mayor en jubilados: XMH = 2.02, RM = 2.74, chi cuadrada: p = 0.03 (IC 95%: 1.03 7.30); 1.15 veces mayor en hombres: XMH = 1.97, RM = 1.61 chi cuadrada: p = 0.04 (IC 95%: 1.00-2.60), y 1.21 veces mayor en el grupo de 65 años o más: XMH = 2.34, RM = 2.21, chi cuadrada: p = 0.01 (IC 95%: 1.12-4.35).

Conclusiones: los resultados de este trabajo son un punto de partida para prevenir, diagnosticar, controlar y dar seguimiento a los casos de TB a nivel delegacional en el IMSS.
