Morbidity pattern of pulmonary tuberculosis and housing quality in Lagos metropolis, Nigeria
The intractable problem of tuberculosis (TB) control despite advances in chemotherapy requires additional research effort to unravel the pertinent factors that make the disease preponderant in developing countries. The present study examined the pattern of TB morbidity in Lagos metropolis with the aim of identifying the explanatory factors. Data on reported cases of pulmonary TB were collected from five DOTS centres (1997 to 2002). Moreover, 120 TB patients were sampled from the DOTS centres so as to provide additional information. Results showed significant variation in the morbidity pattern of TB between residential areas in Lagos metropolis (p < 0.05). Furthermore, TB cases showed a rapid increase between 1997 and 2002. About 58% of TB cases were reported by males, age groups 21-30 and 31-40 accounted for 61.8% while 55.8% of the patients earn below N10,000 monthly. From the regression model, house quality accounted for 67.3% of the morbidity pattern of TB.
