BACKGROUND: In Brazil, arterial hypertension (AH) constitutes one of the main risk factors for chronic kidney disease (CKD). The monitoring of glomerular filtration (GF) is recommended for the assessment of kidney function in hypertensive individuals, as GF decrease precedes symptom onset. OBJECTIVE: To assess GF and its associated factors in hypertensive individuals. METHODS: A cross-sectional study was carried out from January to June 2008 in 297 individuals with arterial hypertension (AH) with or without diabetes mellitus (DM), treated at a primary care facility in the city of São Luís, Maranhão. Patients older than 20 years and of both sexes were included in the study. Sociodemographic and nutritional status data, GF rate and microalbuminuria levels in 24-hour urine were assessed, as well as blood pressure, glucose and serum creatinine levels and a lipidogram. RESULTS: Mean age was 60.6 × 11.5 years, with a predominance of the female sex (75.1%), overweight/obesity (65.0%) and large waist circumference (60.6%). The prevalence of GF 65 years, which remained after adjustment. For the AH group with DM, there was an association between reduced GF and age > 65 years, smoking habit and obesity. However, after the adjustment, age and smoking habit remained as associated factors. CONCLUSION: In these patients, the prevalence of GF 65 years and smoking habit were shown to be factors associated to GF. This reinforces the need to systematically evaluate GF in hypertensive individuals, aiming at the secondary prevention of chronic kidney disease.
