Niveles de antígeno prostático específico total y variables asociadas a cáncer de próstata en varones mayores de 40 años Departamento del Atlántico (Colombia), 2003 / Antigen levels specify total and variables associated to cancer of prostate in greater men of 40 years Department of Atlantic (Colombia), 2003

Objective. Determine the prostate antigen levels and its association with the risk factors related withprostate cancer in male patients older than 40 years and residents of nine towns of Atlántico duringthe period from July to December 2003.Methods. Cross-sectional study in a sample of 839 men older than 40 years, residents in nine townsof Atlántic Department chosen randomly. Total Prostatic – Specific Antigen (tPSA) levels in blood were measured by radioinmunoassay and information regarding family medical history, life-styles, comorbidity,medications, past medical and surgical history was collected through questionnaires. Those whose resultswere 4.0 ng/mL or more, were measured the Free Prostatic Specific Antigen (fPSA).The sample calculationsand the uni and bivariate analysis of the results was performed using Epi-Info version 6.04.Results. A 3.93 percent (n= 33) of the studied population showed high tPSA levels in blood (> 4ng/mL),36.7 percent (n= 308) of the population obtained levels between 2.0 and 4.0 ng/mL and 59.3 percent obtained levels < 2 ng/ml. se realize un análisis bivariado variables: age, marital status, family history of prostate cancer,alcohol and cigarette comsumption, obesity, and urinary symptoms, and there only were statisticalassociation between age and urinary symptoms (p< 0.05).Conclusion. A 3,6 percent of the studied population had high risk of prostate cancer , in function of tPSAand fPSA levels. There were found high percentage of illiteracy and other health conditions due tothe socioeconomic and educational characteristics. Along with health education and information aboutprograms of subsidiary regimens, affirmative actions towards health could be obtained.
