Abstract
Objective
Cervical cancer remains a leading cause of death among women of childbearing age despite the proven efficacy of screening in reducing mortality rates. Women with systemic lupus erythematosus (SLE) are at a higher risk for cervical cancer but tend to have lower screening rates. This study aimed to assess cervical cancer screening (CCS) rates and identify factors influencing screening uptake among Korean women of childbearing age with SLE.
Methods
Women aged 20-49 with SLE and age matched controls, randomly selected at a 1:5 ratio, were identified from the 2016-2017 Korean National Health Insurance Service-National Health Information Database (NHIS-NHID). Data from 10,981 women with SLE and 54,905 controls eligible for National Health Screening Program (NHSP) in 2018-2019 were analyzed. The CCS rate was determined based on participation in Papanicolaou test among eligible individuals for NHSP. Logistic regression was used to estimate odds ratios (ORs) for factors associated with CCS uptake.
Results
The CCS rate was significantly lower in women with SLE compared to controls (49.6% vs 52.1%, P < .0001). Logistic regression revealed that younger age, lower income, self-employment or medical aid insurance, and rural residence were associated with reduced CCS uptake in both groups. The highest CCS uptake occurred in the 40-44 age group for both women with SLE (OR 5.09, 95% CI 4.17-6.22) and controls (OR 4.65, 95% CI 4.26-5.07). Comorbidities increased CCS uptake among controls (OR 1.18, 95% CI 1.13-1.23), but were associated with mild non-significant decrease in uptake among women with SLE (OR 0.96, 95% CI 0.87-1.04).
Conclusion
National CCS program is often underutilized by Korean women of childbearing age with SLE, particularly among those with lower income and those of rural residency. Targeted interventions are needed to improve screening rates and address the unique challenges faced by this high-risk population.
