Knowledge of Chronic Kidney Disease Among the Population of Saudi Arabia Evaluated Using a Validated Questionnaire: A Cross-Sectional Study

Introduction: Public knowledge and awareness regarding chronic kidney disease (CKD) is an important factor influencing the successful implementation of CKD prevention and screening programs. To the best of our knowledge, there are no studies conducted among the Saudi population to explore the public knowledge of CKD using a validated questionnaire. Hence, we explored the knowledge of CKD among the population of the Kingdom of Saudi using a validated questionnaire to determine the level of knowledge regarding CKD as well as the predictors of CKD knowledge. Materials and Methods: This was a cross-sectional online survey study conducted between 12 January 2020 and 11 February 2021. A structured study questionnaire in the Google (TM) platform, with socio-demographic variables and questions assessing CKD knowledge, was used to collect data. A snowball sampling technique was used to recruit participants. Results: A total of 983 people accessed the survey and 951 provided a complete response. Respondents belonging to the age group 41-55 years, having masters or PhD level education, having monthly income >15,000 SR, married, doing >150 minutes/week physical activity had significantly higher kidney disease knowledge. There were significant differences in the mean kidney disease knowledge total score between participants with and without: a history of kidney disease (5.63, df = 895, p<0.001), diabetes mellitus (2.34, df = 949, p = 0.019), hypertension (3.25, df = 949, p = 0.001), and family history of kidney failure (4.60, df = 949, p<0.001). Conclusion: The study revealed a lack of awareness among the Saudi population regarding knowledge about CKD. However, a significantly higher level of knowledge prevailed among respondents from higher educational and higher economic backgrounds. Those with risk factors for CKD also held a greater knowledge about the disease.
