Background: The World Health Organization (WHO) has identified viral hepatitis, particularly caused by HBV
and HCV, as a major global public health threat. These infections lead to significant morbidity and mortality
worldwide, with the number of deaths rising markedly over recent decades. In Nigerian prisons, where male
inmates are disproportionately affected, the prevalence of HBV and HCV is notably high. Socioeconomic
determinants such as risky behaviors, overcrowding, inadequate healthcare access, and food insecurity play
critical roles in exacerbating these infections. Understanding how these determinants intersect and affect
health outcomes in this context is essential for developing targeted interventions and improving public health
strategies. Aim: The aim of this literature review is to critically examine the impact of socioeconomic determinants of
health (SDoH) on the prevalence and outcomes of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections
among male prison inmates in Nigeria. By exploring the intersectionality of risky behaviors, overcrowding,
inadequate healthcare access, and food insecurity, this review seeks to highlight key factors influencing viral
hepatitis transmission and propose strategies for mitigating health disparities within Nigerian prisons.

The World Health Organization (WHO) has identified viral hepatitis,
caused by hepatitis B and hepatitis C viruses (HBV and HCV),
as one of the most significant threats to global public health (WHO
[1]). Viral hepatitis is an inflammation of the liver, predominantly
triggered by viral infections, and is a leading cause of morbidity and
mortality worldwide (Jefferies, et al. [2,3]). The burden of HBV and
HCV is substantial, with the number of deaths rising from 0.89 million
in 1990 to 1.45 million in 2013 (Stanaway, et al. [1,4]). This blood
borne infections are transmitted through contact with infected blood
or body fluids and are major contributors to global mortality, causing
1.4 million deaths annually (WHO [1,5]). Both HBV and HCV can lead
to acute and chronic infections, resulting in progressive liver damage,
cirrhosis, hepatocellular carcinoma (HCC), and death (Berumen, et al.
[6,7]). In 2016, WHO launched a strategy to eradicate viral hepatitis
by 2030, emphasizing prevention, testing, and treatment (WHO [8]).
This review explores the intersectionality of socioeconomic determinants
of health (SDoH) such as risky behaviors, overcrowding, lack of
access to quality healthcare, and food insecurity, and their impact on
the health outcomes of male prison inmates in Nigeria, focusing on
the prevalence of HBV and HCV infections.
Globally, over 10.74 million people are incarcerated, with Africa
having some of the highest prison populations (World Prison Brief,
2024). Nigeria ranks fifth in Africa for prison population, with 78,621
inmates as of March 2024 (World Prison Brief, 2024). The Nigerian
Correctional Service reported 80,507 inmates, 98.2% of whom are
male (Nigerian Correctional Service [9]). Men are more likely than
women to have higher rates of viral hepatitis and other risky behaviors
such as drug injection (Navadeh, et al. [10]). Studies in various
Nigerian prisons have shown high seroprevalence rates for HBV and
HCV, with significant variation across different regions (Adoga ,et al.
[11-15]) Dan-Nwafor, 2021.
Risky behaviors, including sharing needles, injecting drugs, and
non-professional tattooing, significantly contribute to the spread of
HBV and HCV in Nigerian prisons (Mike-Ogburia, et al. [16]). Drug injection
is particularly prevalent among prison populations globally,
with an estimated 58% of people who inject drugs having a history of
incarceration (Degenhardt, et al. [17]). Limited access to harm reduction
services and needle exchange programs exacerbates the risk of
HCV infection (Sander, et al. [18]).
Overcrowding and unsanitary conditions are major SDoH that
impact the health of Nigerian prison inmates. These conditions facilitate
the spread of infectious diseases, including HBV and HCV (World
Health Organization [1]). Overcrowded prisons increase the risk of
transmission through contaminated razors, shared needles, and unprotected
sexual activity (Khan, et al. [19,20]) (Aldridge et al., 2018).
The African judicial system’s inadequacies contribute to prison congestion,
further exacerbating the spread of infections (WHO, [21-23]).
Inadequate access to quality healthcare significantly affects the
ability to diagnose, treat, and monitor HBV and HCV infections in Nigerian
prisons (Ahmed et al., 2019). Health facilities in prisons often
suffer from inadequate staffing, poor equipment, and a lack of essential
supplies (Durojaiye, et al. [24]). This results in many prisoners
receiving subpar care or going undiagnosed, which worsens health
disparities and disease progression (Christopher, et al. [25]). Despite
international declarations advocating for prisoners’ right to healthcare,
access remains limited (United Nations, 2024) (Bretschneider,
et al. [26-28]).
Food and nutrition insecurity are critical SDoH contributing to
health inequalities among Nigerian prisoners. Inadequate access to
nutritionally sufficient and safe foods can lead to chronic diseases
and exacerbate infectious diseases like HBV and HCV (Harding, et al.
[29-33]) (Apel & Powell, 2019). Dietary imbalances are common in
prisons, especially in developing countries, and significantly impact
inmates’ health (Mattei, et al. [34-40]). Addressing food insecurity
is crucial for promoting health and rehabilitation among prisoners
(United Nations, [41]).
A settings approach is advocated to address the health challenges
faced by the prison population, promoting inclusion, and tackling
inequities (Dooris, et al. [42-45]). The ecological model, derived
from Whitehead and Dahlgren’s social model of health, emphasizes
the importance of the environment in determining health outcomes
(Barton, et al. [46]). Implementing health promotion programs and
enhancing access to high-quality healthcare in correctional settings
are essential for improving the health and well-being of inmates (Baybutt,
et al. [47-77]).
This review highlights the significant impact of SDoH on the
health outcomes of male prison inmates in Nigeria, particularly concerning
the prevalence of HBV and HCV infections. Addressing these
issues requires a multifaceted approach involving policy formulation,
research, surveillance, and collaboration among stakeholders. Implementing
WHO recommendations and CDC strategies can significantly
reduce the transmission and spread of viral hepatitis within Nigerian
prisons. Ensuring health equity, preventing disease transmission, and
improving the overall health and well-being of prison populations are
critical steps toward achieving sustainable public health goals.
