Objective:

To determine PSA values and socio-demographic factors associated with its elevation.

Materials and methods:

This research was developed as a cross-cutting descriptive study in which total blood PSA levels were quantified for 97 men over 40 years old, using the Accu-Bind PSA® micro-well ELISA technique; socio-demographic characteristics were investigated; and a bi-variate analysis was made using a p <0.05 level of statistical significance and Odds ratio association (OR).

Results:

The median PSA value in the study population was 0.80 ng/mL (RIQ 0.0 - 2.1); 12.4% of the participants showed results higher than 4 ng/mL, with a population mean age of 59; 49.5% of them were of socio-economic status 1; 46.4% had an elementary school level of education; and 14.4% reported having a family history of prostatic diseases. It was found that age (OR = 5.8; 95 %CI 1.3; 41, p=0.03) is associated with elevated PSA, and that rural origin is related to lower elevation frequency (OR = 0.2, 95 %CI 0.03; 0.8; p=0.04).

Conclusions:

The conduction of these types of studies contributes to the knowledge on any prevalence of regional origin that may impact on the prevention of prostatic diseases.
