Every 2 minutes, a woman dies from cervical cancer, resulting in over 300 000 preventable deaths globally. Nearly all cervical cancers are caused by human papillomavirus (HPV) and are preventable with HPV vaccination and screening through Papanicolaou (Pap) and HPV tests. In Canada, cervical cancer mortality rates have declined in recent decades with more accessible cervical cancer screening programmes. However, screening rates remain low, particularly among Black women and people with a cervix (WPC).

Cervical cancer screening studies of Black WPC in Ontario—Canada’s most populous province—are limited. These studies indicate Black WPCs are at elevated risk for under-screening, with many overdue for screening.

An innovative approach to begin addressing delays is HPV self-sampling (HPVSS). Self-sampling is a cost-effective and more accurate test for detecting high-risk HPV infections associated with precancerous changes versus the Pap test. Self-sampling supports Canada’s action plan—a response to WHO’s global strategy—to eliminate cervical cancer by 2040.

Despite Canada’s plan, research on the state of Black WPCs’ HPV knowledge and self-sampling interventions tailored to them is scant. These scarcities are concerning as Ontario plans to implement HPV primary screening and offer HPVSS soon.

The study objective is to codevelop an HPVSS intervention tailored for and made by Black WPC in Peel region, Ontario. This protocol focuses on phase one of a two-phased study.

In phase one, a qualitative, community-informed approach, co-led by community research assistants, will be used to purposively recruit 10 service providers (eg, clinicians, social workers, community care workers) and 40 Black WPC who will undergo one-on-one semistructured interviews and sociodemographic surveys to explore the state of: (1) Black WPC’s level of HPV, cervical cancer and cervical cancer screening knowledge; (2) Black WPC’s motivators, beliefs, attitudes and misconceptions towards HPVSS; (3) Black WPC’s perceived barriers and facilitators to HPVSS and (4) service providers’ perspectives on Black WPC’s barriers and facilitators to HPVSS. Charmaz’s grounded theory approach and intersectionality will guide data collection and analysis.

Ethical approval has been obtained from the Trillium Health Partners Research Ethics Board (ID#1207). Study findings will be disseminated through community healthcare events, conference presentations, peer-reviewed publications and virtual and physical pamphlets. Additionally, summaries of the findings will be shared and tailored to collaborators, healthcare leadership and researchers and community health centres. Wide dissemination will help enhance understanding of the state of cervical cancer screening, HPV and HPVSS among Black WPC. Given Canada’s commitment to eliminating cervical cancer, study findings will be used to begin developing an HPVSS intervention for Black communities.

This study aims to assess the association between neighbourhood socioeconomic deprivation and outcomes reflecting comprehensive diabetes care (CDC).

Retrospective cohort study

US Medicare Advantage (MA) data, 2015–2020.

National sample of MA enrollees with diabetes.

Primary outcomes included six indicators of CDC from the Healthcare Effectiveness Data and Information Set: haemoglobin (Hb) A1c (HbA1c) testing, HbA1c control (9%), blood pressure control (

There were 827 227 enrolments included in the final analysis. After adjusting for demographic (age, sex, race/ethnicity and dual eligibility) and regional characteristics (rurality and primary care providers per capita), high neighbourhood deprivation was associated only with worse glycaemic control (for HbA1c>9%, risk ratio (RR) 1.04, 95% CI 1.02 to 1.07). This relationship was significant for white and Asian patients (RR 1.08, 95% CI 1.05 to 1.11 and RR 1.18, 95% CI 1.05 to 1.32, respectively); outcomes for black and Hispanic patients were worse overall but independent of neighbourhood deprivation (RR 1.00, 95% CI 0.96 to 1.05 and RR 0.98, 95% CI 0.94 to 1.03, respectively). In the fully adjusted model, neighbourhood deprivation was not associated with measures that directly reflect access to care, including the occurrence of HbA1c testing and receipt of eye exams (RR 0.99, 95% CI 0.94 to 1.04 and RR 1.03, 95% CI 1.00 to 1.05).

An increased risk of poor glycaemic control was observed for patients from areas of high neighbourhood deprivation, independent of individual socioeconomic status. Neighbourhood factors and their intersection with racial and ethnic disparities are important considerations for achieving equity in diabetes care.
