Our aim was to investigate whether receiving a false positive (FP) cervical cytology result affected subsequent cervical cancer screening participation. This Danish nationwide register-based cohort study included 502,380 women aged 22.5–45 attending cervical cancer screening in 2012–2014 with a normal (n = 501,003) or FP (n = 1,377) cytology screening result. A FP result was defined as a cervical cytology showing high grade cytological abnormalities followed by a normal or ‘Cervical Intraepithelial Neoplasia grade 1’ biopsy result. Women were categorized as subsequent participants if they had a cervical cytology within 24–42 months after their last screening or surveillance test. We compared subsequent participation among women with a normal versus a FP result, using odds ratios including 95% confidence intervals. Participation was slightly higher among women with FP results than among women with normal results (71.5% vs. 69.2%, p = 0.058). After adjustment for age and screening history, women with FP results participated significantly more than women with normal results (OR: 1.19, 95% CI 1.06–1.35). Women receiving a FP result did not participate less in subsequent cervical cancer screening than women receiving a normal result. In fact, the use of opportunistic screening seemed to be increased among women receiving a FP result.
