The purpose of this cross-sectional study was to investigate the im.ortance of health vigilance in the prevention of cervical cancer. The sam.le consisted of 536 wom.n. To identify which risk factors were associated with cervical cancer or with an increase in the m.rtality rate of this kind of cancer, a logistic regression m.del was used. The Odds Ratios (OR) and their respective 95% confidence intervals were also calculated. m.st of them.were at the age of highest incidence of cervical cancer (21 - 59 years old), had an unstable conjugal situation, m.nim.l educational level (78.7%), low incom. (58.3%), consum.d alcoholic beverages (56.4%), had a history of sm.king (57.0%) and possessed lim.ted knowledge about the prevention. These results are discussed in term. of a predictive m.del for cervical cancer that considers the im.ortance of public health vigilance in the screening and precocious diagnosis.
