Project description:ImportanceWomen who experience imprisonment have higher rates of cervical cancer. Lack of access to cervical cancer screening in the community or in prison may contribute to increased cervical cancer incidence.ObjectivesTo determine cervical cancer screening rates for women in provincial prison in Ontario, Canada, and to compare these data with data for the general population.Design, setting, and participantsThis retrospective cohort study used correctional and health administrative data from January 1, 2006, to December 31, 2013. Participants included Ontario women aged 21 to 69 years during the follow-up period with no history of cervical cancer or hysterectomy. Analyses were conducted between July 2017 and September 2018.ExposuresWomen admitted to Ontario provincial prison in 2009 or 2010 and released in 2010 were considered exposed, and women in the general population of Ontario were considered unexposed.Main outcomes and measuresWhether women were overdue for cervical cancer screening at the time of admission to prison or on July 1, 2010, for the general population, defined as not having been screened in the previous 3 years, and whether women who were overdue were still overdue after 3 years.ResultsThere were 4553 women in the prison group and 3 647 936 women in the general population group. The median (interquartile range) age was 36 (29-43) years in the prison group and 43 (34-53) years in the general population. Women in the prison group had 2.20 times (95% CI, 2.08-2.33) the odds of being overdue for cervical cancer screening compared with women in the general population after adjusting for neighborhood income quintile, at 53.9% (95% CI, 51.8%-56.1%) compared with 32.9% (95% CI, 32.8%-33.0%) (P < .001). Women in the prison group also had nearly twice the odds of still being overdue at 3 years, with an odds ratio of 1.87 (95% CI, 1.76-1.99) after adjusting for neighborhood income quintile, and rates of still being overdue of 36.2% (95% CI, 34.5%-38.0%) compared with 21.9% (95% CI, 21.8%-21.9%) (P < .001).Conclusions and relevanceWomen who experience imprisonment have worse cervical cancer screening access than women in the general population. Work should be done to promote cervical cancer screening awareness and to improve access to acceptable screening in prison and in the community after prison release.

Project description:Cervical cancer is one of the most common types of cancer among women and is largely preventable with regular screening using Papanicolau (Pap) tests. In Canada, all provinces have regular screening programs, although with slightly differing recommendations. Previous research has found that immigrant women, who are a large proportion of the Canadian population, are at higher risk of being under-screened, or non-adherent to the recommended screening frequency. Using data from the 2017 Canadian Community Health Survey, this study examined: (1) the extent to which immigration status and time since immigration are associated with Pap test adherence in Ontario, and (2) predictors of Pap test adherence for immigrants and Canadian born populations in Ontario, Canada's most populous province, with a focus on the role of racial or ethnic identity among immigrants. Estimates of 3-year test adherence were 71.3 % (95 %CI: 66.9-75.7) among immigrant women and 75.4 % (95 %CI: 73.1-77.1) among non-immigrant women. Recent immigrants (6-10 years in Canada) had lower adherence (63.5 %, 95 %CI: 48.0-80.0). Logistic regression models found that immigrant women had lower adherence than Canadian-born women, controlling for age, household income, education, and having a primary care physician. Subgroup analysis found that South Asian immigrant women were least likely to be adherent. These results support targeted programming to increase screening adherence among recent immigrants and raise concerns regarding potential barriers to screening. Data that allow better disaggregation of racial and ethnic identities are important for better understanding the potential implications of these patterns for racial inequities in health.

Project description:BackgroundThe objective of this scoping study is to review the published literature and summarize findings related to barriers experienced by immigrant women in Canada while accessing cervical cancer screening.MethodsElectronic databases of peer-reviewed articles and grey literature were searched using comprehensive sets of keywords, without restricting the time period or language. Articles were selected based on the following criteria: (a) the study population consisted of Canadian immigrant women and healthcare providers and other stakeholders serving immigrant women, (b) the research focused on the barriers to accessing cervical cancer screening, and (c) the study was conducted in Canada.ResultsExtracted data were grouped and analyzed, resulting in barriers comprised of six themes: economic barriers, cultural barriers, language barriers, healthcare system-related barriers, knowledge-related barriers, and individual-level barriers. Lack of education, low income, preference for a female physician, lack of knowledge, lack of effective communication, and embarrassment were some of the most common barriers mentioned.ConclusionsImmigrant access to health services, including cervical cancer screening, is a complex issue concerning a wide range of barriers. Our findings offer insights into barriers to cervical cancer screening in immigrant communities in Canada that can be used to assist policymakers, healthcare providers, and researchers enhance the health and well-being of these populations by mitigating barriers and improving screening.

Project description:BackgroundPeople with disability, multiple chronic conditions or both may experience challenges in accessing primary care. We aimed to determine the association between appropriate cervical cancer screening and level of disability among women eligible for screening in Ontario and the influence of relevant sociodemographic and health-related variables, including level of morbidity (measured by number of chronic conditions), on screening.MethodsWe used multiple linked databases, including 2 waves of the Canadian Community Health Survey (2005 and 2007/08). Of the 22 824 women included in the study, 7600 reported some level of disability. We used Ontario Health Insurance Plan fee codes to identify appropriate cervical cancer screening.ResultsCompared with women without disability, women with disability were older, less educated, had lower income and had more chronic conditions (36.2% had at least 2 conditions v. 8.4% of women without disability). Women with no disability and no chronic conditions were more frequently screened appropriately than those with severe disability and 2 or more chronic conditions (64.5% v. 39.8%). In multivariable logistic regression analysis, age, rurality, education, marital status and household income were each independently associated with cervical cancer screening. There was a significant interaction between level of morbidity and level of disability. Women with a higher level of disability were less likely to be screened than women with lower level of disability as their level of morbidity increased.ConclusionThe rate of screening for cervical cancer is low among women with both disability and multimorbidity. Policymakers should note these results as they work toward improving cancer screening rates for an aging population with complex medical needs.

Project description:This study reports the first isolation of Candida dubliniensis from North American Indians. Of 39 healthy human hosts sampled, two had C. dubliniensis. Genotypic analysis identified polymorphisms in these strains and differences from two reference strains. Our results suggest that yeast populations from indigenous communities in North America may be unique.

Project description:The genital microbiomes of women varies with racial background. Preterm birth and early-onset neonatal sepsis are two outcomes associated with genital infections during pregnancy. The rate of preterm birth in Aboriginal Australian mothers is high, as is the rate of early-onset sepsis in their infants. To date, no studies have been conducted to investigate genital microbiome taxa associated infection in this group of women. A prospective cohort study to characterize the vaginal and placental microbiomes of a group of these women from the Pilbara region was conducted at the Hedland Health Campus in Western Australia. Included in the study were gravidae Aboriginal (n = 23) and Non-aboriginal (n = 27) women in labor or for planned lower uterine segment Caesarean section. Employing sterile swabs, vaginal samples were obtained under sterile conditions immediately prior to vaginal delivery or planned Caesarean section; and placental samples were obtained under the same conditions during labor. Taxa present in the samples were identified by 16S rRNA amplicon sequencing (V4 region, 515F-806R). Taxon identity and abundance were established from Operational Taxonomic Unit (OTU) counts. Statistical analyses combining clinical metadata and sequencing results were employed to determine associations of taxa with racial background. The findings of this work served to enhance the current understanding of microbiota associated with health and disease in Aboriginal and Non-Aboriginal women. Differences were found between the vaginal and placental microbiomes of Aboriginal and Non-aboriginal women during pregnancy, as well as notable differences between the abundance of specific taxa in each racial group. The relative abundances of specific taxa were significantly different between participants with clinical signs of infection and those with healthy pregnancies. This work will contribute to understanding the causes of differences in rates of infection-driven preterm birth in various racial populations.

Project description:IntroductionBreast cancer is the most commonly diagnosed cancer affecting Australian women, and the second highest cause of cancer death in Australian women. While the incidence of breast cancer is lower in Aboriginal women than non-Aboriginal women, the mortality rate for Aboriginal women is higher, with Aboriginal women 1.2 times more likely to die from the disease. In New South Wales, Aboriginal women are 69% more likely to die from their breast cancer than non-Aboriginal women.Co-design is a research method recognised to enhance collaboration between those doing the research and those impacted by the research; which when used with Aboriginal communities, ensures research and services are relevant, culturally competent and empowers communities as co-researchers. We report the development of a new protocol using co-design methods to improve breast cancer outcomes for Aboriginal women.Methods and analysisThrough a Community Mapping Project in 2018, we co-designed an iterative quantitative and qualitative study consisting of five phases. In Phase 1, we will establish a governance framework. In Phase 2, we will provide information to community members regarding the modified parts of the screening, diagnosis, treatment and follow-up processes and invite them to partake. In Phase 3, the research team will collect data on the outcomes of the modified processes and the outcomes for the women who have and have not participated. The data shall be analysed quantitatively and thematically in Phase 4 with Aboriginal community representatives and reported back to community. Lastly, in Phase 5, we evaluate the co-design process and adapt our protocol for use in partnership with other communities.Ethics and disseminationThis study has ethics approval of the Aboriginal Health and Medical Research Council ref:1525/19. The findings will be published in the literature, presented at conferences and short summaries will be issued via social media.

Project description:ObjectivesTo describe cervical cancer screening participation among women who have sex exclusively with women (WSEW) and women who have sex with women and men (WSWM) compared with women who have sex exclusively with men (WSEM), and women who have never had sex and compare this with bowel (colorectal) and breast screening participation. To explore whether there is evidence of differential stage 3 cervical intraepithelial neoplasia (CIN3) or cervical cancer risk.MethodsWe describe cervical, bowel and breast cancer screening uptake in age groups eligible for the national screening programmes, prevalent CIN3 and cervical cancer at baseline, and incident CIN3 and cervical cancer at five years follow-up, among 218,674 women in UK Biobank, a cohort of healthy volunteers from the UK.ResultsCompared with WSEM, in adjusted analysis [odds ratio (95% confidence interval)], WSEW 0.10 (0.08-0.13), WSWM 0.73 (0.58-0.91), and women who have never had sex 0.02 (0.01-0.02) were less likely to report ever having attended cervical screening. There were no differences when considering bowel cancer screening uptake (p = 0.61). For breast cancer screening, attendance was lower among WSWM 0.79 (0.68 to 0.91) and women who have never had sex 0.47 (0.29-0.58), compared with WSEM. There were incident and prevalent cases of both CIN3 and cervical cancer among WSEW and WSWM. Compared with WSEM with a single male partner, among WSEW there was a twofold increase in CIN3 1.91 (1.01 to 3.59); among WSWM with only one male partner, this was 2.25 (1.19 to 4.24).ConclusionsThese findings highlight the importance of improving uptake of cervical screening among all women who have sex with women and breast screening among WSWM and women who have never had sex.

Project description:BackgroundWomen with a history of incarceration bear a disproportionate burden of cervical disease and have special characteristics that affect their intent and/or ability to adhere to cervical screening and follow-up recommendations. The goal of this study was to identify factors associated with cervical cancer screening and screening outcomes among incarcerated women.MethodsWe applied a framework of predisposing factors, enabling factors and population-specific characteristics that could impact screening behaviors and outcomes for this population. We used bivariate chi-square tests and Wilcoxon signed-rank tests to analyze data previously collected from 290 incarcerated women.ResultsCervical cancer screening belief score, as a predisposing factor, was associated with women who had an up-to-date Pap test and who had a cervical cancer diagnosis ever in their life. Both a sexual history containing high-risk behaviors and a history of abuse, population-specific factors, were each associated with having had an abnormal pap; mental health, incarceration, and substance use histories were each associated with having a diagnosis of cervical cancer.ConclusionsThe significant differences in outcomes for these population-specific factors suggest the need for a health services approach that addresses the challenges to the cervical cancer preventive health needs of incarcerated women.Implications for practiceProviders working with vulnerable populations such as women who have been incarcerated should be aware that their risk histories have an influence on their follow-up behaviors. These women will need extra support for cervical cancer screening and follow-up care.

Project description:Aboriginal women in urban areas have been reported to experience high rates of poverty, homelessness, interpersonal violence, and health problems. However, there are few prior ethnocultural comparisons of urban women from similar socioeconomic backgrounds. The current study explored the mental and physical health of Aboriginal and non-Aboriginal women accessing social services agencies and shelters. Half of the sample (n=172) was Aboriginal (48.3%). The lifetime rate of physical abuse was significantly higher in Aboriginal women, and they were more likely to have been victims of violence or crime in the past year (A=50.6%, NA=35.6%, p<0.05). Rates of teenage pregnancy (<18 years of age) were significantly higher among Aboriginals (A=51.3%, NA=30.6%, p<0.05) and they reported more parental drug/alcohol problems (A=79.2%, NA=56.5%, p<0.05). Aboriginal women were also more likely to have previously received treatment for a drug or alcohol problem. There were no differences in self-reported physical health, medication use, hospitalisations, and current substance misuse. Irrespective of ethnicity, lifetime rates of anxiety, depression and suicide attempts were extremely high. Future research should explore the effects of individual resources (e.g. social support, family relations) and cultural beliefs on women's ability to cope with the stress of living with adverse events, particularly among low SES women with children.
