[Epidemiological Panorama of Cervical Dysplasia in a First-Level Care Unit].

The only factor where a tendency to be associated to type 2 and 3 dysplasia in the population younger than 40 years was the sexually active onset of life younger than 18 years, so this possible association should be evaluated in a bigger population. Our data suggests that risks factors should be evaluated separately for these age groups due to important differences regarding their clinic and epidemiological characteristics as well as changes in risk factor exposure.
