The association between tuberculosis and underlying risk factors was evaluated in Texas patients hospitalized in the 15 counties along the Mexico border within the remaining non-border counties. A case control analysis of the hospital discharge dataset from the Texas Health Care Information Council was performed for the years 1999–2001. A discharge diagnosis of tuberculosis identified cases ( = 4,915). Deep venous thrombosis, pulmonary embolism, and acute appendicitis conditions identified controls ( = 70,808). Risk factors associated with tuberculosis were identified by logistic regression. Diabetes patients were almost twice as likely to have tuberculosis after adjusting by sex, age, and race/ethnicity. The association was strong for the population in the Texas border region, where there are higher incidence rates of tuberculosis (odds ratio [OR] = 1.82; 95% CI = 1.57–2.12) compared with non-border counties (OR = 1.51; 95% CI = 1.36–1.67).
