Factores de riesgo de alteraciones citológicas del cuello uterino en mujeres chilenas: Un estudio de casos y controles / Risk factors associated with abnormal cervical cytology among Chilean women: A case control study
During the study period, there was a significant increase in the proportion of single women, from 8.3 to 14.8 percent (p < 0.05), of women with 3 or more sexual partners from 8.9 to 13.3 and of women high risk HPV, from 9.1 to 14.3 percent. The proportion of abnormal Papanicolaou tests remained stable (3.08 and 3.9 percent > ASCUS). High risk HPV was the most significant factor associated with cervical lesions (odds ratio (OR) = 9.695 percent> confidence intervals (CI) = 4.4-21.1) followed by oral contraceptive use (OR = 2.58 95 percent> CI= 1.2-5.7). Among women infected by high risk HPV, the use of oral contraceptives was a risk factor while compliance with screening was protective for cervical lesions.
Conclusions:
From 2001 to 2006, there was an increase in the proportion of women with high-riskHPV infections.
