[Obstetric-gynecological and social factors for the development of cervical intraepithelial neoplasia].

BACKGROUND

Cervical intraepithelial neoplasia (CIN) precedes cervical cancer and it is associated with risk factors that can be identified in the population, which contribute to timely diagnosis and treatment.

OBJECTIVE

To identify associated risk factors for the development of CIN in women attended at the first level of care.

MATERIAL AND METHODS

A cross-sectional and retrospective study was conducted in women in the 2020-2022 period. Frequencies and means were obtained. For the differences, chi-squared and Student's t were used. Odds ratios (OR) were obtained to assess the risk.

RESULTS

ORs were determined in the group of women with CIN II/CIN III, obtaining risks of almost twice the risk factors analyzed compared to the CIN I group, which had the same factors. When analyzed by age groups < or > 40 years, significant associations were determined in the factors of parity, first cytology in life and positive for smoking. In the group < 40 years and with CIN II/III significant risks were determined in age at first pregnancy < 18 (OR 8.33), first cytology in life (OR 3.77), positive for smoking (OR 3.0), sexual intercourse initiation (SII) before 18 years of age (OR 3.1) and parity (OR 1.3).

CONCLUSIONS

According to the results obtained, sexual and reproductive behavioral factors are of high risk for the development of CIN.
