Objectives: To examine knowledge of chronic kidney disease in the general public.Design: Cross-sectional telephone survey.Setting: Hong Kong.Participants: Community-dwelling adults who spoke Chinese in Hong Kong.
Results:The response rate was 47.3% (516/1091) out of all subjects who were eligible to participate. The final survey population included 516 adults (55.6% female), of whom over 80% had received a secondary level of education or higher. Close to 20% of the participants self-reported a diagnosis of hypertension. Few (17.8%) realised the asymptomatic nature of chronic kidney disease. Less than half of these individuals identified hypertension (43.8%) or diabetes (44.0%) as risk factors of kidney disease. Awareness of high dietary sodium as a risk factor for chronic kidney disease was high (79.5%).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
