The Prevalence Of Helicobacter Pylori Infection Among Student Of Lutheran College Of Health Technology

1.1Background to the study

Helicobacter pylori (H. pylori) infection is one of the most prevalent bacterial infections globally, particularly in developing countries like Nigeria. It colonizes the gastric mucosa and has been strongly associated with various gastrointestinal disorders including chronic gastritis, peptic ulcer disease, gastric adenocarcinoma, and mucosa-associated lymphoid tissue (MALT) lymphoma (Hooi et al., 2017).

According to recent studies, the prevalence of H. pylori infection varies among different populations and geographic regions. In Nigeria, the prevalence rates have been reported to range from 25% to 85% depending on the region and the population studied (Obi et al., 2020). Despite its high prevalence, there is still limited data on the epidemiology of H. pylori infection in specific populations within Nigeria.

Furthermore, there is evidence to suggest that age and sex may be important determinants of H. pylori infection. Several studies have indicated that H. pylori prevalence tends to increase with age, with higher rates observed in older individuals compared to younger ones (Bora et al., 2019). Additionally, some studies have suggested that there may be differences in H. pylori prevalence between males and females, although the findings have been inconsistent (Nirwan et al., 2021).

Understanding the age and sex distribution of H. pylori infection is crucial for developing effective prevention and control strategies. However, limited data are available on this topic, especially within specific populations such as those attending medical centers in regions like Rivers State.

Therefore, this study aims to investigate the age and sex determinants of H. pylori infection among people attending the Lutheran College of Health Technology, Okpoma Yala Rivers State. By examining these factors, we hope to contribute to a better understanding of the prevalence of H. pylori infection in Nigeria and inform the development of targeted interventions to reduce its burden in this population.

1.2 Statement of problem

Helicobacter pylori (H. pylori) infection is a significant public health concern globally, particularly in regions like Nigeria where prevalence rates are high (Amin et al., 2021). Despite advancements in medical research and treatment modalities, the burden of H. pylori-related diseases remains substantial, leading to considerable morbidity and mortality (Safavi et al., 2020). However, there is a dearth of recent data on the epidemiology of H. pylori infection among specific populations, such as those attending medical centers in regions like Rivers State.

One of the key issues surrounding H. pylori infection is its association with various gastrointestinal disorders, including chronic gastritis, peptic ulcer disease, and gastric cancer (Shiota et al., 2020). These conditions not only affect the quality of life of individuals but also impose a significant economic burden on healthcare systems (Asombang et al., 2014). Despite the known association between H. pylori and these diseases, there is still limited understanding of the factors contributing to the high prevalence of H. pylori infection in certain populations.

Age has been identified as a potential determinant of H. pylori infection, with several studies reporting a positive correlation between age and H. pylori prevalence (Ierardi et al., 2019). However, the mechanisms underlying this relationship are not fully understood, and there is a need for more research to elucidate the age-specific patterns of H. pylori infection in different populations (Sung et al., 2020). Moreover, the impact of age on the clinical outcomes of H. pylori-associated diseases remains unclear, highlighting the importance of further investigation in this area.

Sex differences in H. pylori prevalence have also been reported, although the findings have been inconsistent across studies (Miftahussurur et al., 2021). Some studies suggest that males may have a higher prevalence of H. pylori infection compared to females, while others have found no significant difference between the sexes (Ierardi et al., 2020). The reasons for these discrepancies are not well understood and may be influenced by factors such as genetic predisposition, hormonal differences, and sociocultural factors (Talebi Bezmin Abadi, 2018).

Additionally, there is a lack of data on the prevalence of antibiotic resistance among H. pylori strains in Nigeria, which could have important implications for treatment outcomes (Okoli et al., 2019). The emergence of antibiotic-resistant strains poses a significant challenge to the management of H. pylori infection and underscores the importance of surveillance and antimicrobial stewardship programs (Sung et al., 2021).

Overall, the lack of recent epidemiological data on H. pylori infection among specific populations, such as those attending medical centers in regions like Rivers, State, hinders our ability to develop targeted prevention and control strategies. Therefore, there is an urgent need for research to address these knowledge gaps and inform evidence-based approaches to mitigate the burden of H. pylori-related diseases in Nigeria and other resource-limited settings.
