Population knowledge on chronic kidney disease, its risk factors and means of prevention: a population-based study in Fortaleza, Ceará, Brazil.

INTRODUCTION: Chronic kidney disease (CKD) has been increasing significantly. There is evidence that a large part of the population does not have enough knowledge on the subject. OBJECTIVE: To investigate the level of knowledge about CKD in the general population, its risk factors and means of prevention. METHODS: We ran a cross-sectional study in the population of Fortaleza, Ceará - Brazil, between 2017 and 2020, with the application of a questionnaire on CKD, risk factors and prevention. RESULTS: we interviewed 735 volunteers, with a mean age of 38 years, of which 55% were female. Only 17.2% correctly responded to the concept of CKD, and 5.8% knew the concept of creatinine. Low water intake was the most cited risk factor by respondents (79.3%). The main risk factors and direct causes of CKD (diabetes and hypertension) were mentioned less frequently (13.2% and 15.1%, respectively). Men were more correct regarding risk factors and ways to prevent CKD. Older respondents answered more correctly the questions about the definition of CKD (n = 22; 28.6%) and creatinine (n = 7; 9.0%). With regards to education there was a statistically significant correlation in all the questions (p < 0.05). CONCLUSION: There is little knowledge about CKD in the general population. Higher level of education is associated with better knowledge. More health education actions are needed so that the population becomes better acquainted with CKD and, consequently, can adopt more adequate prevention and control measures.

Renal Health: Providing Information and Technological Tools to Empower Patients to Live Better with Kidney Disease.

Chronic kidney disease (CKD) is a growing Public Health problem. Recent evidence points that low education and poor socio-economic conditions are associated with higher risk of developing CKD and progressing to dialysis or transplantation need. Hence patient empowerment through health education and qualification with technological tools that allows better treatment adherence may play an important role in the achievement of optimal clinical outcomes. The Renal Health is a multidisciplinary project created at the University of Fortaleza, northeast Brazil, in 2015, aiming to create novel educational material and technological tools for people with CKD, in different treatment modalities, including dialysis and transplant. The products developed so far in the project include an application for smartphones aiming to help patients in dialysis and transplant in their treatments, including schedule for medications, with alarms, water ingestion control, laboratory tests results, and medical appointments' agenda, besides all information regarding CKD. The other tools include a medication box, an insole for weight control (both are in the prototype phase), connection with smartbands (for vital signs monitoring) and multimedia educational tools, including a profile in the Instagram and a channel in YouTube. Since the first release of the application in the virtual stores, there were more than 1,000 downloads, predominantly in Brazil, although the app is also available in English and Spanish. All these tools represent innovative ways of patient empowerment and may be increasingly present in daily life. Further studies are required to assess the impact of these tools in patients' outcomes, including CKD progression and mortality.

Resumo Introdução: A doença renal crônica (DRC) vem aumentando de forma significativa. Há evidências de que grande parte da população não tem conhecimento suficiente sobre o assunto. Objetivo: Investigar na população geral o nível de conhecimento sobre a DRC, seus fatores de risco e meios de prevenção. Métodos: Foi realizado estudo transversal na população de Fortaleza, Ceará, Brasil, entre 2017 e 2020, com aplicação de um questionário sobre DRC, fatores de risco e prevenção. Resultados: Foram entrevistados 735 voluntários, com média de idade de 38 anos, dos quais 55% eram do sexo feminino. Apenas 17,2% responderam corretamente ao conceito de DRC, e 5,8% sabiam o conceito de creatinina. A baixa ingestão hídrica foi o fator de risco mais citado pelos entrevistados (79,3%). Os principais fatores de risco e as causas diretas de DRC (diabetes e hipertensão) foram mencionados com menor frequência (13,2% e 15,1%, respectivamente). Os homens tiveram maior acerto com relação aos fatores de risco e às formas de prevenção da DRC. Os entrevistados com idade mais avançada responderam mais corretamente às perguntas sobre a definição de DRC (n = 22; 28,6%) e creatinina (n = 7; 9,0%). No que diz respeito à escolaridade, em todas as perguntas houve correlação estatisticamente significativa (p < 0,05). Conclusão: Há um baixo nível de conhecimento sobre a DRC na população geral. Maior nível de escolaridade associa-se a um melhor conhecimento. São necessárias mais ações de educação em saúde para que a população conheça melhor a DRC e consequentemente possa adotar medidas de prevenção e controle mais adequadas.
