Predictors of cervical cancer screening service utilization among commercial sex workers in Northwest Ethiopia: a case-control study.

Background: Although an opportunistic approach of cervical cancer screening strategy had been implemented in Ethiopia, utilization of screening services among women is still low, accounted < 1%. We hypothesize that commercial sex women in Ethiopia faced a number of obstacles in order to access screening services. Identifying the predictors influencing utilizations of the screening services is an essential effort to tailor screening program towards increasing the utilization.
Methods: An unmatched case-control study was implemented with a total sample size of 230 (46 cases and 184 controls). The study was conducted among commercial sex workers who attended confidential clinic opened for sex workers. Simple random sampling was employed. After the data were checked for completeness, consistency and accuracy, it was entered in to Epi nfo version 7 then exported to SPSS for further statistical analysis. Descriptive statistics were used to describe the profile of study participants. Logistic regression was employed to identify the predictors of cervical cancer screening uptake. P < 0.05 was computed to determine the level of statistical significance.
Results: Cervical cancer screening utilization was associated with providers' recommendation (AOR = 6.8; 95% CI: 2.3, 9.7), history of sexually transmitted infection (AOR = 6.9; 95% CI: 1.29, 7.2), frequency of facility visit (AOR = 4.8; 95% CI: 1.97, 11.8) and history of vaginal examination (AOR = 0.21; 95% CI: 0.1, 0.68).
Conclusions: The level of cervical cancer screening service utilization was higher among women with history of STI, frequency of facility visit and providers' recommendation. The level of cervical cancer screening service utilization was lower in women with previous vaginal examination.
