Clinical and social characteristics of the patients with tuberculosis in Eastern Anatolia.

Tuberculosis (TB) is an important public-health problem. The risk factors for TB are well-known. However, there may be some regional differences. In this study, we aimed to investigate the demographic characteristics and regional risk factors for TB and to discuss possible explanations for the difference. The study included totally 253 hospitalized patients (145 male and 108 female, with an average age 38+/-18) with TB (117 pulmonary and 136 extrapulmonary) between 1997 and 2004. Their demographic and clinical characteristics were reviewed. TB frequency was higher among the non-working females in urban area (38.3%). TB was also common in farmers which are male (19.8%). TB frequency was higher in the school persons including students, the teachers and the school officials (14.6%) and in the building workers compared with the other workers. There were a history of previous TB, TB exposure (mostly from family members) and associated disease in 10.3%, 14.2% and 17.4% of cases, respectively. The most encountered associated disease was diabetes. The results indicate that TB was most common among non-working females and was also increased among the men in rural areas, and schools seem to be an important source of TB transmission. Thus, an effective control program covering the treatment of cases with active disease, such as directly observed treatment, and especially preventive measures should be considered to control the disease transmission in our region.
