# Prevalence and Associated Factors of Uncontrolled Hypertension Among Patients Attending Primary Healthcare Centers in Riyadh, Saudi Arabia

## TL;DR

This study found that over 60% of hypertension patients in Riyadh had uncontrolled blood pressure, with factors like smoking, poor medication adherence, and employment increasing the risk.

## Contribution

The study provides new evidence on the prevalence and contributing factors of uncontrolled hypertension in Saudi Arabia's primary healthcare settings.

## Key findings

- 62.4% of patients had uncontrolled hypertension.
- Smoking and stopping medication after feeling better were significant risk factors.
- Higher education was protective, while employment increased the risk of uncontrolled HTN.

## Abstract

Background

Hypertension (HTN) is a global health issue as it causes significant mortality and morbidity among the worldwide population. Various treatments are available, but many patients are unable to control the disease. There are various factors like medication non-adherence and lifestyle habits that contribute to this problem. There is a need for evidence-based interventions to address HTN effectively, especially in regions like Saudi Arabia, where there is limited data on uncontrolled HTN. This study aimed to assess the prevalence of uncontrolled HTN and contributing factors to poor blood pressure control among patients in Primary Health Centers (PHCs) in Riyadh, Saudi Arabia.

Methodology

An analytical cross-sectional study was conducted using an interviewer-administered questionnaire among all patients aged 18 years and above who have uncontrolled HTN and who visited the PHCs of Riyadh's first health cluster in Saudi Arabia. Data was cleaned in Microsoft Excel and analyzed using IBM SPSS 29.

Results

The study comprised 516 patients with HTN. The majority were males (53.1%, n=274) compared to females (46.9%, n=242), with an average age of 58 years (SD=10.5). Notably, most patients were obese (63.2%, n=326), and 62.4% (n=322) had uncontrolled HTN. Multivariate analysis identified sociodemographic factors like higher education (p-value = 0.013, adjusted odds ratio (AOR) = 0.795) as protective against uncontrolled HTN, while employment (p-value = 0.031, AOR = 1.786) increased the risk of uncontrolled HTN. Risk factors such as smoking (p-value = 0.001, AOR = 3.011) and salt restriction (p-value = 0.021, AOR = 0.643) significantly influenced HTN control. Management-related predictors like stopping medication after feeling better (p-value = 0.001, AOR = 3.196) were also found significant.

Conclusion

This study revealed a high prevalence of uncontrolled HTN, especially among males and obese individuals. Sociodemographic factors like higher education were protective, while employment increased the risk of the disease. Further, smoking, salt restriction, and medication adherence significantly impacted HTN control, highlighting the importance of tailored interventions.
