Prevalence of the chronic renal insufficiency by means of the Cockcroft-Gault and Diet modification in the renal disease formulas. Matanzas. 2010. Rev. Med. Electrón.

Fundament: the chronic renal insufficiency is the gradual, progressive and irreversible lost of the renal functions. The Cockcroft-Gault and the Diet Modification in the renal disease formulas are the most used ones for its diagnosis. In Matanzas they had been used in population studies.  Objectives: calculating the prevalence of the chronic renal insufficiency in the municipality of Matanzas and comparing both formulas. Methods: we carried out a cross-sectional descriptive research. The sample was composed by 2 326 persons. The used variables were age, genre, weight, size, skin color, and serum creatinine. We used the confidence intervals of 95 % to compare the prevalence of both methods. Results: the prevalence was 6,4 per 100 people for the Cockcroft-Gault, and 5,0 for the Diet Modification in the Renal Disease. There it was a direct increase in relation with age; the female genre was the most affected, and also the white skin color. There were not significant differences between the data of both methods in the analysis of these variables. The average of the glomerular filtrate was higher by means of the Cockcroft-Gault. Also the prevalence in the 65-74 age group and in the persons with healthy weight was higher for this equation. Conclusions: we consider that both methods are valid for calculating the glomerular filtrate and therefore for the diagnosis of the chronic renal insufficiency, because of its easiness and low cost, when working with big population groups.
