Introduction: Cervical cancer is a global public health problem, and is the second leading cause of death in Peru; the study was conducted more in populations of large cities, leaving aside other populations that could have a significant risk. Objective: To determine the prevalence and factors associated with abnormal cervical cytologic findings in women of fishermen in a city in northern Peru. Methods: Cross-sectional analytical research of secondary data, convenience sampling was performed in women with active sex life in a semi urban population of northern Peru. The principal variable was the finding of pre invasive and invasive cervical lesions observed by cytology, crossed with other social, gynecological and sexual variables; statistical finding of crude and adjusted association. Results: Of the 144 respondents, 20% had a cytological alteration and the 26% had not taken the test over 3 years ago. 14% were positive for squamous intra epithelial lesion low grade, 1% had an invasive squamous carcinoma. When performing multivariate analysis, an association between cytological lesion and HPV (p<0.001), having severe inflammation (p<0.001), having a germ (p=0.001) and initiating sexual intercourse at age 14 or less (p=0.024), adjusted for contraceptive use and Pap tests have been done. Conclusions: Some associated factors in a sexually active population, reflecting a high prevalence of injury associated with factors that have to be operated.
