Provincial variation in colorectal cancer screening adherence in Canada; evidence from the Canadian Partnership for Tomorrow’s Health
The researchers investigated how social and medical characteristics influence adherence to breast cancer screening in Canada. They used data from five regional cohorts of the Canadian Partnership for Tomorrow’s Health (CanPath): the BC Generations Project (BCGP), Alberta’s Tomorrow Project (ATP), the Ontario Health Study (OHS), Quebec’s CARTaGENE, and the Atlantic Partnership for Tomorrow’s Health Study (Atlantic PATH). They analyzed self-reported data on screening mammography among 79,986 participants aged 50-74 and 46,907 participants aged 40-49. Most participants reported undergoing screening within two years of enrollment, with rates ranging from 77.8% in OHS to 86.3% in BCGP. Factors linked to lower odds of screening included lower household income, being single or never married, current daily smoking, poor self-perceived health, no history of breastfeeding, and longer intervals since the last routine medical check-up. Among women aged 40-49 with a first-degree family history of breast cancer, screening adherence varied by region and was lower among those post-menopause or with longer intervals since medical check-ups. These findings highlight key factors for targeting underserved communities and suggest that early screening guidelines may benefit from considering regional differences and individual health characteristics.
Covert vascular brain injury and cognitive dysfunction among Chinese adults living in Canada and China
The researchers examined how country of residence influences covert cerebrovascular disease (VBI) and cognitive dysfunction among Chinese adults living in Canada and China. The study compared Chinese adults in Canada and China. They found that people in Canada had a lower prevalence of covert VBI and cognitive dysfunction than those living in China, even though both groups shared the same ethnicity. Living in China was associated with a much higher risk of covert VBI and lower cognitive function, although the link between cognitive dysfunction and country of residence was explained by education and traditional cerebrovascular risk factors, such as blood pressure and cholesterol.
Investigating Skin Cancer Risk and Sun Safety Practices Among LGBTQ+ Communities in Canada
The researchers conducted a national survey of 700 LGBTQ+ individuals to evaluate skin cancer risk factors, sun-protective behaviors, and related concerns. Some participants were recruited with the help of longitudinal cohorts, notably the Manitoba Tomorrow Project and Atlantic PATH. The researchers found that 60% reported over 10 lifetime sunburns, 58% experienced at least one blistering sunburn, 34% had used tanning beds, and 69% reported having a tan in the last 12 months. Regular sunscreen use was reported by only half of the respondents. These findings emphasize the urgent need for culturally sensitive public health campaigns targeting sun safety practices within the LGBTQ+ community.
Exposure to air pollutants and subclinical carotid atherosclerosis measured by magnetic resonance imaging: A cross-sectional analysis
The researchers examined how long-term exposure to air pollution affects early signs of heart disease. They used data to explore whether low levels of air pollutants are linked to the thickening of artery walls. The study included 6,645 adults from five Canadian provinces and estimated their exposure to nitrogen dioxide (NO₂), ozone (O₃), and fine particulate matter (PM2.5) over several years. Using MRI scans to measure carotid artery wall thickness, the researchers found mixed results. Higher levels of ozone were linked to thicker artery walls, suggesting a potential negative effect, while higher nitrogen dioxide levels were associated with thinner artery walls, a finding that requires further investigation.
A comprehensive analysis of skin cancer concerns and protective practices in Manitoba, Canada, highlights lack of skin cancer awareness and predominance of high-risk sun exposure behaviors
The researchers conducted a cross-sectional survey using data from Manitoba’s Tomorrow Project to examine sun exposure behaviors and attitudes. They found that over 65% of participants reported a history of sunburns, more than 50% had used tanning beds, and fewer than 50% used sunscreen. These findings highlight critical gaps in sun protection practices and awareness, underscoring the urgent need for targeted public health interventions to reduce skin cancer rates.
Development and external validation of partial proportional odds risk prediction models for cancer stage at diagnosis among males and females in Canada
This study examined health patterns in Alberta’s Tomorrow Project participants before cancer diagnosis to find factors related to cancers caught early versus late. The researchers found factors then tested them in a similar group from the British Columbia Generations Project.
Provincial variation in colorectal cancer screening adherence in Canada; evidence from the Canadian Partnership for Tomorrow’s Health
The researchers sought to assess regional variation in screening uptake, identify factors to non-adherence to screening, and estimate adherence to screening in those with differing risk profiles. Using national CanPath data, they found adherence suboptimal amongst Canadians and noticed variation by region.
Mental health, cancer risk, and the mediating role of lifestyle factors in the CARTaGENE cohort study
This study investigates the associations between depression, anxiety, and cancer risk and the mediating effects of lifestyle. Using data from 34,571 CARTaGENE participants, researchers found positive links between mental health disorders, all cancers, and lung cancer risk, except for anxiety and lung cancer in women, where associations were lower when adjusting for sociodemographics, health and lifestyle. The study also found that smoking affected the relationship between mental health disorders and cancer risk. Overall, the study suggests that lifestyle factors, like smoking, may be important in understanding the relationship between mental health and cancer risk.
Examining the influence of built environment on sleep disruption
Researchers sought to understand if modifying aspects of the built environment improved sleep. Using data from 28,385 BC Generations Project participants, they found that increased light-at-night, air pollution (SO2), and living <100 m from a main roadway were associated with insufficient sleep. Greenness had a positive effect on sleep.
Agreement between self-report and administrative health data on occurrence of non-cancer chronic disease among participants of the BC generations project
Linked self-reported chronic disease history data to a Chronic Disease Registry (CDR) that applied algorithms to administrative health data to ascertain diagnoses of multiple chronic diseases in the Province of British Columbia.
