Population impact of factors associated with prevalent pulmonary tuberculosis in Tanzania

Looks at the demographic and clinical factors associated with bacteriologically TB in the adult population of Tanzania

Abstract

Tanzania has an estimated tuberculosis (TB) prevalence of 295 per 100 000 adult population. There is currently no nationally representative information on factors associated with TB in Tanzania. Study used a case-control study nested in a nationally representative TB prevalence survey. All patients with bacteriologically confirmed pulmonary TB (PTB) constituted cases and a representative sample of people without bacteriologically confirmed PTB constituted controls. We calculated adjusted odds ratios (aORs) to identify factors associated with TB.

This paper concludes that being in an older age group, being male and having a low BMI were associated with bacteriologically confirmed PTB. On the population level, classic risk factors for TB have no major effect on prevalent TB from which future transmission may occur.
