(A) Association between demographics, health behaviours, comorbid conditions and survey year and reduced kidney function (CKD stages G3a–G5). Reference categories: age: 55–64 years; gender: male; educational level:<8 years; living in urban area; current smoker; survey year: 2009–2010. Estimate not shown for persons 18–54 due to the very low prevalence of reduced kidney function at younger ages. (B) Association between demographics, health behaviours, comorbid conditions and survey year and increased albuminuria (A2–A3). Reference categories: age: 40–49 years old; gender: male; educational level:<8 years; living in urban area; BMI category: normal (18.5–25 kg/m²); survey-defined diabetes only; survey year: 2009–2010. Variables not significant at 5% level in individual models were dropped from the final model. BMI, body mass index; CKD, chronic kidney disease; ENS, Encuesta Nacional de Salud.
