Background: Hypertension is the leading source of morbidity and death. There is still a significant divide between high-income and low-to-middle-income countries in awareness, management, and control in the twenty-first century. Objectives: To assess the adults’(> 18 years old) awareness of hypertension risk factors in Tabuk, Saudi Arabia. Methods: A descriptive cross-sectional, questionnaire-based research design was used to assess the adults’ awareness of hypertension risk factors in Saudi Arabia. An online survey was conducted among Saudi adults in January 2023 using an online questionnaire platform in Google Forms. Results: The present study included 223 participants. 41.3% of participants were aged 18-27 years old, most of them were females 76.7%, more than half of them had a Bachelor’s degree 54.3%, and jobless 65.5%. Most of them live in urban areas 74.9%. 88.8% are non-smokers. Most of the participants were not hypertensive patients 88.3%, P value = 0.543. 3.1% of hypertensive patients had HTN less than a year or 1-3 years ago. Most of the participants had their knowledge from the internet and awareness campaigns. Conclusion: The general awareness of HTN risk factors was acceptable. In order to reduce financial loss, national studies should be carried out to evaluate the general attitudes, knowledge, and practices of hypertensive patients. The importance of adequate teaching regarding HTN risk factors in Saudi Arabia is emphasized by this study. Making policies to raise awareness about the risk factors of hypertension is recommended.
