Abstract
Cervical cancer is preventable and treatable through regular screening and follow-up. However, the utilization of cervical cancer screening may vary widely based on individual lifestyles. The purpose of this study was to examine the differences in the adherence to cervical cancer screening guidelines in various dietary groups. Our study included 21,376 women from the United States and Canada, aged 30-69 from the Adventist Health Study-2, a large population-based prospective cohort study. Modified Poisson regression with robust variance estimation was used to determine the prevalence ratios of cervical cancer screening behavior in participants following five different dietary patterns (non-vegetarians, semi-vegetarians, pesco-vegetarians, lacto-ovo-vegetarians, and vegans). All analyses were adjusted for age, race/ethnicity, marital status, education, personal income, body mass index, smoking, alcohol use, exercise, and family history of all female cancer. Vegetarians, in general, had similar screening prevalence as non-vegetarians. However, vegans were 16% less likely to have had a Pap test compared to non-vegetarians (prevalence ratio (PR) = 0.84, 95% confidence interval 0.81-0.86). Women who were younger, Black, married, more educated, had a family history of all female cancer, had a higher income, and exercise reported higher compliance to a Pap test. It remains to be seen whether vegan women in Adventist Health-2 experience a higher incidence of cervical cancer or are diagnosed at a later stage compared to non-vegetarians.

Correlates of cervical cancer underscreening in women with varying levels of healthcare interactions in a United States integrated delivery system. Prev Med 2021; 145:106410. [PMID: 33388329 PMCID: PMC7956225 DOI: 10.1016/j.ypmed.2020.106410] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Revised: 10/22/2020] [Accepted: 12/28/2020] [Indexed: 01/14/2023]
Abstract
One in five U.S. women with health insurance are underscreened for cervical cancer. We sought to identify whether underscreening correlates differed among women with different levels of health care interaction. Among women age 30-64 years who were members of an integrated U.S. health system, we used 2014-2015 electronic health record data to identify underscreened cases (≥3.4 years since last Papanicolaou (Pap) test, n=3352) and screening-adherent controls (<3.4 years since last Pap test, n=45,359) and extracted data on potential underscreening correlates (demographics, health history, and healthcare utilization). We calculated the odds of underscreening in the total population and by subgroups defined by healthcare visits and online health portal usage in the prior 12 months. Underscreening was associated with older age (50-64 vs. 30-39; odds ratio (OR)=1.6; 95%CI=1.4-1.8), current tobacco use (vs. never use; OR=2.1; 95%CI=1.8-2.2), higher BMI (≥35 kg/m2 vs <25 kg/m2, OR=2.0; 95%CI=1.8-2.3), screening non-adherence for colorectal cancer (OR=5.1; 95%CI=4.6-5.7) and breast cancer (OR=8.1, 95%CI=7.2-9.0), and having no recent visit with their primary care provider (PCP) nor recent health portal use (vs. recent PCP visit and portal use; OR=8.4, 95%CI=7.6-9.4). Underscreening correlates were similar between the total study population and within all healthcare interaction groups. Interaction with the healthcare system is associated with lower odds of underscreening, but sociodemographic and health status correlates are similar regardless of primary care visits or online portal use. These data support the need for additional interventions to reach insured women who remain underscreened for cervical cancer.

[PMID: 29277629 DOI: 10.1016/j.ajog.2017.12.209] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2017] [Revised: 12/12/2017] [Accepted: 12/18/2017] [Indexed: 11/26/2022]
Abstract
BACKGROUND The latest 2012 US Preventive Services Task Force cervical cancer screening guidelines recommended screening initiation at age 21 years. Little is known about the cervical cancer screening initiation practices in the community and whether there are critical gaps with respect to adherence to current clinical guidelines. Despite an overall decline in cervical cancer incidence across women of all ages, the incidence rate has not declined among 24-25 year olds between 2000 (2.79 per 100,000) and 2013 (2.93 per 100,000). Thus, it is important to understand cervical cancer screening initiation in young women and how woman- and provider-level factors affect the timing of screening initiation to identify areas for improving cervical cancer prevention. OBJECTIVE We examined patterns and correlates of cervical cancer screening initiation among women turning age 21 years in a large community-based practice. STUDY DESIGN Female members of Kaiser Permanente Southern California who turned age 21 years (baseline) during 2013-2015 and had not previously received a Papanicolaou test were included. Cervical cancer screening initiation through October 2016 was captured using electronic health records. Incidence rate and cumulative incidence of screening initiation was calculated. Associations between patient and provider characteristics and screening initiation were evaluated using multivariable Cox models. RESULTS A total of 38,257 women were included and the Papanicolaou screening initiation rate was 44 per 100 person-years during the study period. Approximately 40% initiated screening within 1 year after turning age 21 years. In multivariable analyses, Asian/Pacific Islanders (hazard ratio, 0.91; confidence interval, 0.86-0.96 compared with non-Hispanic whites); Medicaid enrollees (hazard ratio, 0.90; confidence interval, 0.83, 0.97); those whose primary language is not English (hazard ratio, 0.71; confidence interval, 0.67, 0.75); those who have a historical inpatient visit, primary care physician in pediatrics, internal medicine, or another specialty compared with family practice; and have a male rather than female primary care physician (hazard ratio, 0.46; confidence interval, 0.36, 0.57) less often initiated screening. On the other hand, those who used other preventive services such as getting a human papilloma virus and influenza vaccination and those with a history of pregnancy, contraception use, and sexually transmitted infections more often had timely screening initiation. CONCLUSION Less than half of the women insured for preventative services initiated screening at age 21 years. Strategies to improve adherence to screening initiation guidelines should consider a tailored approach for at-risk subgroups and addressing initiation challenges associated with male physicians.

J Racial Ethn Health Disparities 2016; 4:10.1007/s40615-016-0304-2. [PMID: 27864808 PMCID: PMC5436953 DOI: 10.1007/s40615-016-0304-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2016] [Revised: 10/06/2016] [Accepted: 10/13/2016] [Indexed: 11/24/2022]
Abstract
INTRODUCTION Racial and ethnic disparities continue to exist in cancer screening rates, especially among US Latina and Black/African American populations. We conducted six focus groups among 41 women from these communities in order to better understand their preferences about cancer screening reminders and the motivators and deterrents they face in obtaining recommended breast, cervical, and colon cancer screening. METHODS Using self-reported patient race/ethnicity from electronic medical records of a large, integrated health care system in Seattle, we recruited women ages 30-60 to participate in one of five 2-hour focus groups. Using verbatim transcripts from these discussions, we conducted a qualitative analysis to identify common themes. RESULTS The focus group participants were primarily strong endorsers and utilizers of recommended breast, cervical, and colon cancer screening services. Insurance and belief in preventive care were the most common motivators that they cited in obtaining cancer screening. However, they still reported multiple barriers to getting recommended cancer screening for themselves and community members, including lack of time, conflicting information about screening intervals, distrust in the health care system, and a lack of understanding of the benefits of preventive care. CONCLUSIONS Efforts to improve understanding about the benefits of cancer screening, clarify cancer screening guideline recommendations, increase cultural competency among health care professionals, and expand the times and locations where cancer screening is available are all options that may improve cancer screening rates among Latinas and Black/African American women.

Abstract
OBJECTIVE Test-specific reminder letters can improve cancer screening adherence. Little is known about the effectiveness of a reminder system that targets the whole person by including multiple screening recommendations per letter. METHODS We compared the effectiveness of a Pap-specific reminder letter sent 27months after a woman's last Pap, to a reminder letter that included up to seven preventive service recommendations sent before a woman's birthday ("birthday letter") on Pap smear adherence from a natural experiment occurring in routine clinical care. Participants included 82,016 women from Washington State who received 72,615 Pap-specific letters between 2003 and 2007 and 100,218 birthday letters between 2009 and 2012. We defined adherence as having a Pap test within a six month window around the Pap test due date. Using logistic regression, we calculated adjusted odds ratios (OR) for adherence with 95% confidence intervals (CI) following the birthday letter with 1-2 recommendations, 3-5 recommendations, and 6-7 recommendations compared to the Pap-specific letter. All analyses were stratified by whether a woman was up-to-date or overdue for screening at the time she received a letter. RESULTS Adjusted ORs showed reduced adherence following the birthday letter compared with the Pap-specific letter for up-to-date women whether the letter had 1-2 recommendations (OR=0.37, 95%CI=0.36-0.39), 3-5 recommendations (OR=0.44, 95%CI=0.42-0.45), or 6-7 recommendations (OR=0.36, 95%CI=0.32-0.40). We noted no difference in Pap-test adherence between letter types for overdue women. CONCLUSIONS In conclusion, for women regularly adherent to screening, an annual birthday letter containing reminders for multiple preventive services was less effective at promoting cervical cancer screening compared with a Pap-specific letter.
