Factors Associated with the Development of Chronic Kidney Disease in Patients with Arterial Hypertension

Introduction: Chronic kidney disease affects a large part of the population with hypertension, diabetes mellitus as well as those over 50 years of age. Research reported that male sex and other comorbidities such as obesity and anemia are more frequent in Chronic kidney disease, as well as uncontrolled diabetes mellitus or hypertension. Objective: To determine the risk factors associated with the development of chronic kidney disease in adults with arterial hypertension. Material and Methods: Retrospective cohort study of 455 patients with hypertension treated in a primary health care hospital. Medical records and laboratory information were reviewed for the diagnosis of chronic kidney disease and its staging. Patients aged 40 years and older, of both sexes and evaluated between the years 2015 −2017 were included. Logistic regression analysis allowed the identification of risk factors associated with the development of chronic kidney disease. Results: 63.7% were female and 36.3% male. The average age for 2015 was 69.79 ± 9.03, more than half of participants had diabetes mellitus and controlled hypertension and the predominant nephroprotection was with Losartan (53%) that year. Male sex (OR 1.68, CI 1.03–2,76), age: 60 years or older (OR 6.38, CI 2.65–15,37) and anemia (OR 1.71, CI 1.03–2,85), were risk factors for the development of chronic kidney disease (p < 0.05), whereas nephroprotection (OR 0.39, CI 0.18–0,88) and controlled diabetes mellitus (OR: 0.18, CI 0.07–0,47) were shown to be protective factors (p < 0.05). The prevalence of chronic kidney disease between 2015 and 2017 was 19% and 45%, respectively, with predominance of category G2. The comparison group is the same cohort analyzed in each year under study. Conclusion: Male sex, age over 60 years, and anemia are risk factors for chronic kidney disease. Nephroprotection, controlled diabetes mellitus, and patient follow-up are factors that prevent its development.
