Estimated glomerular filtration rate (eGFR) and urinary albumin (U-Alb) have been suggested as indicators for the early identification of persons with kidney dysfunction. The Gubbio Study collected data on serum creatinine, UAlb, other laboratory indices, blood pressure, and medical history in a population sample of 4574 adults (2083 men and 2491 women, age range 18- 95 years). The study included analyses on six disorders which are commonly associated with kidney disease (hypertension, cardiovascular disease, anemia, high serum uric acid, high serum phosphorus/low serum calcium, and high serum potassium). Low eGFR (<60 mL/min per 1.73 m2) was found in 6.6% of men and 6.2% of women. Low eGFR prevalence varied largely with age (from <1% at 18-24 years up to > 30% at > or =75 years in both sexes, p<0.001). On the basis of these data, it was estimated that the prevalence of low eGFR in the whole Italian population could be 1.3 million among men (95%CI 1.1/1.5) and 1.5 million among women (95%CI 1.3/1.8). Data available only for age 45-64 indicate that 6.4% of men and 3.0% of women have high U-Alb (> or =20 microg/min) in the presence of non-low eGFR. Low eGFR was associated with at least two disorders potentially due to kidney disease in the majority of persons but was rarely associated with a previous diagnosis of kidney disease (<5% of cases). These data support the use of eGFR for the screening of people with or at risk of developing kidney disease. Awareness of kidney disease is very low in the Italian population.
