Cervical cancer rates have declined in industrialized nations as a result of cytology screening programs. However, there are still sizeable differences in screening adherence in Spain. This study aimed to identify the prevalence of cervical cancer screening among women in Spain, to analyze trends in that prevalence from 2017 and 2020 and to identify socio-demographic, health, and lifestyle factors related with adherence to this screening test. We conducted a cross-sectional study of 13,619 women aged 25−65 who participated in the 2017 Spanish National Health Survey and the 2020 European Health Survey for Spain. We used logistic regression to examine the relationship between socio-demographic, health and lifestyle factors and cervical cancer adherence. The prevalence of adherence was 73.18%. Additionally, there was a significant decrease in cervical cancer screening uptake from 2017 and 2020 among women aged 25−44 years (2017: 77.80%, 2020: 75.20%, p = 0.02), but an increase in the age group of 45−65 years (2017: 68.93%, 2020: 72.39%, p < 0.01) and in foreigners (2017: 64.29%, 2020: 72.29%, p < 0.01). Screening for cervical cancer is related with age, educational level, social class, insurance status, visits to the family doctor, alcohol consumption and free time physical exercise.
