PREVALENCE AND RISK FACTORS OF HYPERTENSION AMONG CIVIL SERVANTS: A CASE STUDY OF NATIONAL HOSPITAL ABUJA

ABSTRACT

Hypertension, a major risk factor for cardiovascular diseases, stroke, and renal failure, is increasingly prevalent among working populations in Nigeria, with civil servants constituting a particularly vulnerable group due to the sedentary nature of their work, chronic occupational stress, and lifestyle-related risk factors. This study examines the prevalence and risk factors of hypertension among civil servants attending the National Hospital Abuja. A cross-sectional study design was adopted, involving 400 civil servants selected through stratified random sampling. Blood pressure measurements, anthropometric assessments, and structured questionnaire data were collected and analysed using SPSS version 26. conclusions and recommendations for workplace health promotion, routine screening programmes, dietary modification, and stress management interventions tailored to civil servants. The study addresses critical gaps in occupational hypertension research in Nigeria’s public service sector and offers guidance for policy and programmatic interventions.

 

1.0 INTRODUCTION

1.1 BACKGROUND OF THE STUDY

Hypertension has been discussed as a silent killer due to its rather insidious nature, which often leads to late diagnosis and treatment of hypertension (Poulter et al., 2015). It is a major contributable risk factor to the disability-adjusted life years (DALYs) globally and contributes disproportionately to the premature mortality in LMICs, where access to healthcare and essential medicines remains limited (GBD 2019 Risk Factors Collaborators, 2020).

High blood pressure or hypertension is a non-communicable disease (NCD) that is chronic in nature, irrespective of gender, age, ethnicity, and geographic location (World Health Organization [WHO], 2021). It is one of the most common and impactful public health issues on a global scale affecting an estimated 1.28 billion adults globally and contributing significantly to the global burden of cardiovascular disease, stroke, chronic kidney disease, and premature mortality (WHO, 2023). Sub-Saharan Africa has one of the highest hypertension prevalence rates that have increased tremendously over the last three decades, as a direct result of rapid urbanisation, dietary changes, physical inactivity, and the substantial increase in psychosocial stressors (Adeloye et al., 2021).

With a population of over 200 million, Nigeria carries one of the highest burden of hypertension on the African continent. Hypertension prevalence rates have been estimated in in-country studies involving population samples of Nigerian adults ranging from 22.5% to 38.1% of the adult population, with higher prevalence rates in urban areas (Eze et al., 2022; Ogah et al., 2019). Of specific interest is the increasing nature of hypertension in Nigeria given the already overstretched healthcare system, lack of access to antihypertensives, and low levels of awareness, treatment and control even among the already diagnosed patients (Ataklte et al., 2015).

The civil servants should be a special focus among particular occupational groups in Nigeria since it is a high-risk group in terms of hypertension. Their working conditions are typified by excessive sedentary activities, excessive bureaucratic stress levels, distorted eating habits, and lack of physical exercise during working hours (Ikeda et al., 2018). More so, civil servants find themselves in occupations of social prestige, with or without potentially competing lifestyle demands, such as alcohol consumption during social events and dietary habits that are associated to increased cardiovascular risk. In spite of these established risk factors, specific epidemiological studies in hypertension of civil servants in Nigeria are relatively scarce.

The National Hospital Abuja (NHA), a federal tertiary health institution that was founded in 1999, is a centre of excellence in the provision of healthcare services in the Federal Capital Territory and beyond. Since NHA has a large population of civil service clients who are employed in federal ministries, departments as well as agencies, it makes NHA an ideal environment to be able to learn the prevalence of hypertension and risk factors in this occupation group. This paper thus evaluates the prevalence and risk factors of hypertension among civil servants who are employed in the National Hospital, Abuja, with the object of coming up with evidence to inform specific preventive interventions.

The epidemiology of hypertension in Nigeria reflects the nationwide trend in sub-Saharan Africa, where urbaningradients, socioeconomic disparities, and nutrition transition interact to generate increasingly rising prevalence rates (Adeloye et al., 2021). Studies like the Nigerian Sentinel Community Disease Surveillance (NSCDS) and subsequent rounds of the National Demographic and Health Survey have reported an increase in the prevalence of hypertension in all age groups, with working-age adults showing particularly worrisome trends (National Population Commission [NPC] & ICF, 2019).

The Nigerian civil servants work in a federal bureaucracy with high job demands where decision-making latitude is limited and where job security is weak and policy disruptions frequent, all of which are established psychosocial risk factors leading to hypertension under the job-strain model proposed by Karasek (1979) and subsequently validated in numerous study paper occupational health literature (Theorell and Karasek, 1996). The interaction between occupational stress and unhealthy lifestyle behaviours is the resultant synergist risk profile increasing the risk of hypertension far above the norm.

The concentration of federal civil servants in Abuja forms a unique epidemiological environment. There is a paucity of studies with complete risk factor analyses of current diagnostic criteria and strong sampling approaches at the National Hospital level, though several studies of this type have been reported at the level of hospitals (Severini et al., 2016). This paper fills these gaps through the employment of rigorous epidemiological methodologies.

 

1.2 STATEMENT OF THE PROBLEM

Hypertension contributes to a significant and increasingly large percentage of morbidity and mortality of adult working-age populations in Nigeria. The hypertension risk is high in civil servants as a large and strategically important occupational group is exposed to a constellation of occupational, behavioural, and metabolic risk factors. Nevertheless, civil servant-specific hypertension management programmes along with regular screening of blood pressure are largely missing in the Nigeria public health infrastructure.

Informal clinical observation at the National Hospital Abuja indicates that a considerable percentage of civilian servants visiting the facility either present themselves with not yet diagnosed hypertension or are non-compliant with prescribed antihypertensive medication. But the exact prevalence, the profile of risk factors, and the dynamics of awareness, treatment, and control amongst this population has not been systematically researched in this institution. The empirical gap will limit the formulation of focused workplace health promotion programme and clinical management approach.

Moreover, the implications of economic productivity of the uncontrolled hypertension among civil servants are significant, among them increased absenteeism, poor work performance, growing healthcare costs incurred by government employers and pre-mature retirement due to complications that arise as a result of uncontrolled hypertension. To solve this issue there is need to have a clear evidence base that defines the epidemiological burden and the landscape of the risk factors and this study is aimed to present this evidence base.

1.3 OBJECTIVES OF THE STUDY

The broad objective of this study is to determine the prevalence and risk factors of hypertension among civil servants at the National Hospital, Abuja. The specific objectives are to:

1. Determine the prevalence of hypertension among civil servants attending the National Hospital, Abuja.
2. Assess the levels of hypertension awareness, treatment, and control among the study population.
3. Identify the modifiable lifestyle risk factors associated with hypertension among civil servants at the National Hospital, Abuja.
4. Examine the association between occupational stress and hypertension among civil servants in the study.
5. Recommend evidence-based strategies for hypertension prevention and control among civil servants in Nigeria.

 

1.4 RESEARCH QUESTIONS

This study is guided by the following research questions:

1. What is the prevalence of hypertension among civil servants attending the National Hospital, Abuja?
2. What are the levels of hypertension awareness, treatment, and control among the study population?
3. What modifiable lifestyle risk factors are significantly associated with hypertension among civil servants at the National Hospital, Abuja?
4. Is there a significant association between occupational stress and hypertension in the study population?
5. What evidence-based strategies can effectively prevent and control hypertension among Nigerian civil servants?

 

1.5 RESEARCH HYPOTHESES

The following null hypotheses are tested in this study:

H01: There is no significant association between modifiable lifestyle risk factors (physical inactivity, dietary patterns, tobacco use, alcohol consumption) and hypertension prevalence among civil servants at the National Hospital, Abuja.

H02: There is no significant relationship between occupational stress levels and hypertension status among civil servants in the study population.

H03: There is no significant difference in hypertension prevalence across socio-demographic groups (age, gender, educational level, and cadre of service) among the study population.

 

1.6 SIGNIFICANCE OF THE STUDY

This study makes several important contributions to public health knowledge and practice in Nigeria. By providing current, facility-based prevalence data on hypertension among civil servants at the National Hospital Abuja, the study generates evidence directly applicable to the development of workplace health policies within the federal public service. The findings will be of direct relevance to the Office of the Head of the Civil Service of the Federation, the Federal Ministry of Health, and the National Health Insurance Authority in designing comprehensive employee health and wellness programmes.

From a clinical standpoint, the study’s assessment of hypertension awareness, treatment, and control rates will inform the development of enhanced screening protocols, patient education interventions, and adherence support systems at the National Hospital and similar facilities serving government workers. The identification of modifiable risk factors provides a practical basis for lifestyle intervention programmes that can be integrated into staff welfare activities at federal ministries.

Academically, the study enriches the growing body of occupational health literature in Nigeria, addresses documented gaps in hypertension epidemiology research among civil servants, and provides a replicable methodological model for similar investigations across other states and occupational groups. It also contributes to the validation of the job-strain model in the Nigerian civil service context.

 

1.7 SCOPE OF THE STUDY

This study is restricted to civil servants aged 18–60 years who attended the National Hospital Abuja for any clinical services between January and May 2023. The study focuses specifically on hypertension as defined by the American Heart Association (AHA) and American College of Cardiology (ACC) 2017 guidelines (Whelton et al., 2018), as well as the WHO/International Society of Hypertension (ISH) 2020 guidelines. The study does not examine other non-communicable diseases, although relevant comorbidities are noted as confounding variables. The study’s cross-sectional design precludes causal inference, and findings are specific to the National Hospital Abuja setting.
