Introduction. Prisoners in Sub-Saharan Africa (SSA) are at a high risk of tuberculosis (TB) infection due to overcrowding and poor
ventilation. Consequently, TB is a leading cause of morbidity and mortality in prison, and many inmates face a number of barriers
to TB control and had limited information in the region. Thus, the aim of this systematic review and meta-analysis was to estimate
the overall pooled prevalence of pulmonary TB and predictors among prison inmates in SSA. Methods. From 2006 to 2019, a
systematic review and meta-analysis was conducted using various databases, including PubMed, Embase, Web of Science, and
Scopus. The data were extracted in Microsoft Excel using a standardized data extraction format, and the analysis was carried
out with STATA version 14. To detect heterogeneity across studies, the I
2
and the Cochrane Q test statistics were computed.
To determine the overall prevalence of TB and predictors among prison populations, a random effect meta-analysis model was
used. Results. Of the 3,479 retrieved articles, 37studies comprising 72,844 inmates met the inclusion criteria. The pooled
prevalence of pulmonary TB among prison inmates in SSA was 7.74% (95% CI: 6.46-8.47). In the subgroup analysis, the
highest prevalence was found in the Democratic Republic Congo (DRC) (19.72%) followed by Zambia (11.68%) and then
Ethiopia (9.22%). TB/HIV coinfection (OR 4.99 (95% CI: 2.60-9.58)), Body mass index (BMI < 18:5) (OR 3.62 (95% CI: 2.65-
6.49)), incarceration (OR 4.52 (95% CI: 2.31-5.68)), and previous TB exposure (OR 2.43 (95% CI: 1.61-3.56)) had higher odds
of pulmonary TB among inmates. Conclusion. The prevalence of pulmonary TB among SSA prison inmates was found to be
high as compared to total population. TB/HIV coinfection, BMI, incarceration duration, and TB exposure were all predictors
with pulmonary tuberculosis in prison inmates. As a result, emphasizing early screening for prisoners at risk of pulmonary TB
is an important point to achieving global TB commitments in resource-limited settings.
1. Background
Tuberculosis (TB) is an airborne infectious disease mainly
caused by Mycobacterium tuberculosis (MTB), which is still
a major public health issue affecting person of all ages [1].
Adults in their most productive years are primarily affected,
which accounted 88% [2, 3]. Globally, an estimated 10 mil-
lion people developed TB disease in 2019, and there are 1.2
