A Matched Case-Control Study to Identify Risk Determinants of Tuberculosis in Bangladesh
According to the estimates of 2015, the global incidence rate for tuberculosis (TB) is 142 per 100,000 population . In Bangladesh, the prevalence rate of TB is 382 per 100,000 population and incidence rate is 225 per 100,000 population , . Over the years researchers primarily focused on socio- economic, cultural, and biological factors as the determinants of causation of TB. According to Hargreaves et al. (2011), global socio- economic inequalities, high population mobility, and rapid urbanization influenced key social determinants of TB such as malnutrition, food insecurity, poor environmental conditions, financial, cultural, and geographical factors . These social determinants, in turn, affect the four stages pathogenesis of TB: exposure to infection, progression to disease, diagnosis and treatment, adherence, and success. According to WHO 2016 report, TB epidemic is more severe than it was previously estimated . As developing countries in Asia and Africa are carrying major TB burden  and often face difficulties in accessing medical care, social and economic determinants of TB must be appropriately addressed together with the adequate implementation of the TB prevention programs.
