Introduction: Globally, the burden of Tuberculosis is escalating. Early diagnosis and prompt initiation of treatment are essential to achieve an effective tuberculosis control programme. Objective: To investigate the duration of delay for treatment and assess the determinants of treatment delays among pulmonary tuberculosis patients in Enugu metropolis, SouthEast , Nigeria. Methods: This cross sectional study was conducted among 219 pulmonary tuberculosis patients in six randomly selected DOTS centres in the three LGAs in Enugu metropolis. Data were analysed using SPSS version 17, and statistical significance of association between variables was assessed using Chi-square test at p < 0.05. STATA version 13.1 was used to calculate the positive predictors of TB treatment delays using logistic regression. Ethical clearance was obtained from the Health Research Ethics Committee of UNTH and verbal informed consent was obtained from the participants. Results: Overall, 291 respondents took part in the study, 55.7% were males, 84.4% were aged between 16 to 60 years, while their mean age was 35.4 ± 12.6 years. Most of the participants 32.9%, 26.9%, 15.5% were traders, civil servants, and students respectively. Among the respondents, 3.6% knew that Mycobacterium tuberculosis is the cause of tuberculosis. Among the participants, only 23.3% presented for first appropriate treatment consultation within 1-30 days of onset of symptoms. The reasons given by the respondents for the delay are: ignorance of necessity treatment (36.1%), Lack of money (24.2%), no health facility close to the house (13.2%), and other reasons 26.5%. Delay in treatment was found to be significantly associated with HIV status (X 2 = 23.412, df = 8, p = 0.003), knowledge of the cause of TB (X 2 = 42.322, df = 28, p = 0.040), TB symptoms experienced (X 2 = 46.857, df = 20, p = 0.001), occupation (X 2 = 34.217, df = 20, p = 0.025), and distance of the health facility from the respondents' residence (X 2 = 34.908, df = 8, p = 0.000). The positive predictors of delayed treatment, using logistic regression, were first presentation at: patent medicine
