Introduction: Nigeria has one of the highest tuberculosis (TB) burdens in the world with estimated  incidence of 133 per 100,000 populations. Multi-drug resistant TB (MDR-TB) is an emerging threat of the  TB control in Nigeria caused mainly by incomplete treatment. This study explored factors that affect  adherence to treatment among patients undergoing direct observation of TB treatment in Plateau state,  Nigeria.

Methods: Between June and July 2011, we reviewed medical records and interviewed randomly selected pulmonary TB patients in their eighth month of treatment. Information on patients? clinical, socio- demographic and behavioral characteristics was collected using checklist and structured questionnaire for knowledge of treatment duration and reasons for interruption of treatment. We conducted focus group discussions with patients about barriers to treatment adherence. Data were analyzed with Epi Info  software.

Results: Of 378 records reviewed, 229 (61%) patients were male; mean age 37.6 ±13.5 years and 71 (19%) interrupted their treatment. Interruption of treatment was associated with living > 5 km from TB treatment site (AOR: 11.3; CI 95%: 5.7-22.2), lack of knowledge of duration of treatment (AOR: 6.1; CI 95%: 2.8-13.2) and cigarette smoking (AOR: 3.4; CI 95%: 1.5- 8.0). Major reasons for the interruption were lack of transport fare (40%) and feeling well (25%). Focused group discussions revealed unfriendly attitudes of health care workers as barriers to adherence to treatment.

Conclusion: This study revealed knowledge of the patients on the duration of treatment, distance and health workers  attitude as the major determinants of adherent to TB treatment. Training for health care workers on  patient education was conducted during routine supportive supervision.
