Association of Pregnancy History and Cervical Cancer Screening in a Community Sample of Sexual Minority Women

Participation, barriers, and facilitators of cancer screening among LGBTQ+ populations: A review of the literature

The LGBTQ+ community is at higher risk of certain cancers but is less likely to participate in screening programs or engage with preventive healthcare. Despite this, the barriers and facilitators to cancer screening are not well understood in this population. We conducted a literature review of research related to LGBTQ+ participation in cancer screening, as well as barriers and facilitators to participation. Following abstract and full-text screening, 50 studies were included in the final synthesis. Compared to their heterosexual counterparts, lesbian and bisexual women were less likely to participate in cervical cancer screening and mammography, but gay and bisexual men were more likely to participate in anal and colorectal cancer screening. Transgender individuals had lower rates of screening than cisgender individuals for all cancer types. Barriers to participation were found at the individual-, provider-, and administrator-level, and good communication with a healthcare provider was the strongest facilitator. These results provide reasonable first steps toward improving participation rates for LGBTQ+ populations in cancer screening. Patient-centered approaches should draw on core guiding principles to inform the provision of care, including anticipating LGBTQ+ patients, improving knowledge about care for these patients, and confronting individually-held biases that may affect care, in order to improve care experiences and participation rates in preventive services.

Breast and cervical cancer screening adherence in Jiangsu, China: An ecological perspective

Background

High screening coverage can effectively reduce the mortality in breast and cervical cancer. Further research on extending the coverage of breast and cervical cancer screening in China is required. This study explored factors influencing women's "two-cancer" screening service utilization using an ecological approach.

Methods

Data were obtained from the National Health Services Survey (NHSS) conducted in 2018 in Jiangsu, China. A total of 3,500 women aged 18-64 years were included in the analysis. Chi-squared test, hierarchical multiple logistic regression analysis, and binary logistic regression analysis were performed.

Results

In total, 44.1% of the women had been screened for breast cancer (BC) and 40.9% for cervical cancer (CC). Breast cancer screening (BCS) and cervical cancer screening (CCS) differed significantly in the following common categories: age, gestational experiences, chronic disease status, body mass index (BMI), exercise, health checkup, marital status, number of children, employment, education, family doctors, and health records. In the results of hierarchical multiple logistic regression analysis, the explanatory power of the final model was 37.5% and the area under the receiver operating characteristic curve was 0.812. The results showed that being in the age group of 35-64 years, having gestational experiences, having chronic diseases, exercising, having a health checkup, being married, having children, and being employed were statistically significant positive predictors of "two-cancer" screening adherence. The household size was a barrier. For BCS, obesity was also a negative factor, and a higher overall self-related health status was a positive factor. Being married and living in households of three or more families were not predictors. For CCS, having health records was also positively significant, while having chronic disease did not influence adherence.

Conclusion

The findings provide an ecological explanation for women's BCS and CCS service utilization. Both proximal and distal factors should be considered to achieve a high coverage rate.

Papanicolaou Test Rates Among Sexual Minority Women: A Systematic Review and Meta-Analysis

Purpose: The purpose of this review was to compare differences in Papanicolaou (pap) test rates between sexual minority women (SMW) and heterosexual women. Methods: PubMed, Embase, and Scopus were searched from inception until June 2020 for articles reporting pap test rates among SMW. Studies were selected if they included pap test rates for SMW with a comparison rate for heterosexual women; studies were excluded if they did not report pap test rates. A quality assessment scale was used to assess study quality. A random-effects model was employed to calculate pooled odds ratios (ORs) for each outcome along with 95% confidence intervals (CI). Heterogeneity was assessed by implementation of the I² statistic, and L'Abbe plots were inspected visually to assess for homogeneity. Sensitivity analyses were performed by omitting each study sequentially and analyzing the overall impact of that study on the pooled results. Meta-regression was conducted to identify potential causes of heterogeneity among any statistically significant outcomes by an examination of the covariable of insurance coverage. Results: We identified 21 cross-sectional studies comprising 24,207 SMW and 546,259 heterosexual women that met inclusion criteria. Overall, studies were of a fair quality. When compared with heterosexual women, SMW received less frequent pap tests (OR 0.58, 95% CI 0.48-0.71, 21 studies, 24,207 SMW, 546,259 heterosexual women). Compared with heterosexual women, lesbian women had routine pap tests less frequently (OR 0.46, 95% CI 0.37-0.56, 17 studies, 9595 lesbian women and 516,760 heterosexual women). Meta-regression for insurance status did not alter these results. Conclusion: SMW, in general, and lesbian women, in particular, receive pap tests less frequently than heterosexual women. The reasons for this disparity should be investigated to better serve the needs of this population. PROSPERO Registration: CRD#42020191887.

Cervical Cancer Screening Participation among Women of Russian, Somali, and Kurdish Origin Compared with the General Finnish Population: A Register-Based Study

Migrant-origin women are less prone to cervical screening uptake compared with host populations. This study examined cervical cancer screening participation and factors associated with it in the Finnish mass screening program during 2008–2012 in women of Russian, Somali and Kurdish origin compared with the general Finnish population (Finns) in Finland. The study population consists of samples from the Finnish Migrant Health and Well-being Study 2010–2012 and Health 2011 Survey; aged 30–64 (n = 2579). Data from the Finnish screening register linked with other population-based registry data were utilized. For statistical analysis we employed logistic regression. Age-adjusted screening participation rates were Russians 63% (95% CI: 59.9–66.6), Somalis 19% (16.4–21.6), Kurds 69% (66.6–71.1), and Finns 67% (63.3–69.8). In the multiple-adjusted model with Finns as the reference; odds ratios for screening were among Russians 0.92 (0.74–1.16), Somalis 0.16 (0.11–0.22), and Kurds 1.37 (1.02–1.83). Among all women, the substantial factor for increased screening likelihood was hospital care related to pregnancy/birth 1.73 (1.27–2.35), gynecological 2.47 (1.65–3.68), or other reasons 1.53 (1.12–2.08). Screening participation was lower among students and retirees. In conclusion, screening among the migrant-origin women varies, being significantly lowest among Somalis compared with Finns. Efforts using culturally tailored/population-specific approaches may be beneficial in increasing screening participation among women of migrant-origin.

Barriers and Facilitators to Cervical Screening among Migrant Women of African Origin: A Qualitative Study in Finland

Globally, cervical cancer constitutes a substantial public health concern. Evidence recommends regular cervical cancer screening (CCS) for early detection of "precancerous lesions."Understanding the factors influencing screening participation among various groups is imperative for improving screening protocols and coverage. This study aimed to explore barriers and facilitators to CCS participation in women of Nigerian, Ghanaian, Cameroonian, and Kenyan origin in Finland. We utilized a qualitative design and conducted eight focus group discussions (FGDs) in English, with women aged 27-45 years (n = 30). The FGDs were tape-recorded, transcribed verbatim, and analyzed utilizing the inductive content analysis approach. The main barriers to CCS participation included limited language proficiency, lack of screening awareness, misunderstanding of screening's purpose, and miscomprehension of the CCS results. Facilitators were free-of-charge screening, reproductive health services utilization, and women's understanding of CCS's importance for early detection of cervical cancer. In conclusion, among women, the main barriers to CCS participation were language difficulties and lack of screening information. Enhancing screening participation amongst these migrant populations would benefit from appropriate information about the CCS. Those women with limited language skills and not utilizing reproductive health services need more attention from healthcare authorities about screening importance. Culturally tailored screening intervention programs might also be helpful.

Predicting cervical cancer screening among sexual minority women using Classification and Regression Tree analysis

Cervical cancer screening is a critical preventive healthcare service for all women. Sexual minority women (SMW) in the United States experience multiple health disparities including decreased access to and use of cervical cancer screening. The mechanisms driving these disparities are not clear and SMW with multiple marginalized identities may be more likely to miss recommended cervical cancer screening. This study aimed to identify subgroups of SMW that are more and less likely to be screened for cervical cancer according to American Cancer Society guidelines. We used cross-sectional data from the latest (2010-2012) wave of the Chicago Health and Life Experiences of Women (CHLEW) Study (N = 691). Informed by intersectionality theory, we performed classification and regression tree (CART) modeling to construct a data-driven, predictive model of subgroups of SMW who were more and less likely to receive guideline-recommended screening. Notably, the CART model did not include commonly tested variables such as race/ethnicity or level of income or education. The model did identify subgroups with low likelihood of receiving screening and several novel variables that may be important in understanding SMW's use of cervical cancer screening; lifetime number of sexual partners, age at drinking onset, childhood physical abuse, and internalized homonegativity. Our results point to the importance of early life experiences and identity development processes in shaping patterns of preventive healthcare use among adult SMW. Our analysis also demonstrated the potential value of CART modeling techniques for evaluating how multiple variables interact in complex ways to predict cervical cancer screening.
