VELOSA, Teresa Luísa et al. Prevalence of stage 3-5 chronic kidney disease in diabetic patients aged 60 or over. Rev Port Med Geral Fam [online]. 2018, vol.34, n.3, pp.128-138. ISSN 2182-5173.

Objectives: To estimate the prevalence of stage 3-5 chronic kidney disease (CKD3-5) in elderly patients with type 2 diabetes mellitus (T2DM). Study design: Quantitative, observational, and descriptive with an analytical component. Setting: The study was conducted at Unidade de Saúde Familiar (USF) Lígios, between June 1, 2013 and June 31, 2014. Participants: Patients with T2DM aged 60 or over, monitored at USF Lígios. Methods: Healthcare professionals completed questionnaires with patients' data: gender, age, height, weight, body mass index, schooling, alcohol consumption, smoking habits, blood pressure, nephrotoxic medication, creatinine, estimated glomerular filtration rate (eGFR) (using the modification of diet in renal disease [MDRD] formula), urea, albuminuria, and haematuria. Results: In this sample, the prevalence of CKD3-5 in the T2DM aged 60 or over was 15%. The prevalence of CKD3-5 increased with age (60-74 years: 10.5%; 75-84 years: 19.4%; ≥85 years: 39.1%, p<0.01), and was positively associated with illiteracy (eGFR ≥60ml/min/1.73m²: 11.6%; eGFR <60ml/min/1.73m²: 21.2%, p<0.05), and negatively associated with alcohol consumption (p<0.05). The prevalence of persistent albuminuria in the sample was 16.8%. There was a statistically significant relationship between smoking habits and persistent albuminuria (albumin/creatinine ratio [ACR] <30mg/g: 3.5%; ACR ≥30mg/g: 10.3%, p<0.05). Conclusion: The prevalence of CKD3-5 in this sample of T2DM patients aged 60 or over was 15.0%, and the prevalence of persistent albuminuria was 16.8%.
