Public Unawareness of Renal Function: A Questionnaire Survey at a Health Promotion Seminar

Background: Progression of chronic kidney disease (CKD) increases the risk of complications such as cardiovascular disease; however, knowledge regarding renal function in the general population is low. We aimed to determine factors necessitating CKD education in the general population. Methods: Participants for a health promotion seminar were recruited via the Sugiura Memorial Foundation website and Sugi Pharmacy stores. Those who agreed to participate in the seminar were included in the questionnaire survey after a health seminar. Results: Out of 1548 participants, 1050 answered all questionnaire items, resulting in a valid response rate of 67.83%. Multivariable analysis revealed that sex (OR = 0.611), pharmacy consultations (OR = 0.661), receiving a blood test within 1 year (OR = 0.268), awareness of blood pressure (OR = 0.038), and knowledge of blood glucose level (OR = 0.099) were factors for unawareness of renal function. Conclusions: This study suggests that female individuals unaware of their blood pressure or glucose levels, those who have not had a blood test within 1 year, and those who have not sought health consultations need education on renal function.
