[Kidney function in marginalized population: a pilot study].
BACKGROUND
Chronic kidney disease (CKD) is a public health problem; more than 6 % of worldwide population suffers from it. Low education and socioeconomic status, as well as limited access to medical care increase the probability of kidney damage. The objective was to evaluate and classify renal function in Yucatan's marginalized population.


METHODS
A transversal descriptive survey was carried out among non-hospitalized adults of a general hospital. The study population included marginalized subjects (confirmed by socioeconomic survey), without oedema, pregnancy or diabetes mellitus. Renal function was evaluated by glomerular filtration rate. Patients were staged according to KDOQI guidelines. Likewise, weight, height, body mass index (BMI), fat percentage and blood pressure were measured. The results were compared between gender groups as well as rural and urban population.


RESULTS
165 subjects were included (83 % female). High risk of kidney damage was observed in 44.2 % of patients; 1.8 %, 49.1 %, and 4.8 % were in stages 1 to 3, respectively. There was no difference when comparing data between different groups.


CONCLUSIONS
This study found high prevalence of CKD in Yucatan's marginalized population.
