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.
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.
Dietary Intake and the Neighbourhood Environment in the BC Generations Project
This study examined how neighbourhood factors like access to amenities and social relationships, as well as greenness and walkability, can influence fruit and vegetable intake. ~28,000 participants from the BC Generations Project were involved. Those living in neighbourhoods with greater material and social deprivation were less likely to meet recommendations for fruit and vegetable consumption, while those living in neighbourhoods with higher greenness were more likely to meet recommendations. These findings highlight how multiple neighbourhood characteristics can impact dietary intake.
Harnessing the power of data linkage to enrich the cancer research ecosystem in Canada
This abstract discusses a project aimed at linking cancer registry and administrative health data to Canada’s largest population health study, the Canadian Partnership for Tomorrow’s Health (CanPath). The project seeks to enrich the cancer research ecosystem in Canada by providing researchers with a comprehensive dataset that includes genetics, environment, lifestyle, and behaviour data. The linked data will be made available through a cloud-based solution called the CanPath Data Safe Haven, which is accessible to researchers through secure access. The project will address concerns related to the accessibility of cancer data in Canada, bring more value to existing data, and support an enhanced understanding of the impacts of cancer on marginalized populations.
Lifestyle factors and lung cancer risk among never smokers in the Canadian Partnership for Tomorrow’s Health (CanPath)
Data from 950 CanPath participants were analyzed to understand why 15-25% of lung cancers occur in never smokers. Researchers found a link between lung cancer risk, sleep, and fruit and vegetable intake amongst never smokers.
Predictors of CRC Stage at Diagnosis among Male and Female Adults Participating in a Prospective Cohort Study: Findings from Alberta’s Tomorrow Project
This study aimed to uncover factors associated with colorectal cancer (CRC) at diagnosis in 267 Alberta Tomorrow Project participants. Researchers found that social support, having children, and caffeine intake were strong CRC stage predictors at diagnosis for males. In contrast, CRC family history, pregnancy, hysterectomy, menopausal hormone therapy, Pap test lifetime number, and household physical activity were strong CRC predictors at diagnosis for females.
Metabolomics and cancer preventive behaviors in the BC Generations Project
To better understand links between behaviours and cancer, researchers measured metabolites in blood samples from 1,319 BC Generations Project participants. The study found a large number of metabolites were different between health behaviours. Highlights include lower levels of metabolites that are involved in pathways that play a role in cancer development among participants who consumed more fruits and vegetables and had a healthy body weight.
Diet Quality and Neighborhood Environment in the Atlantic Partnership for Tomorrow’s Health Project
This study looked at the differences that exist beween diet quality and someone’s geographical location. It was found that diet quality tended to be lower in areas that were were more socially deprived. Areas with socially deprived and high-density areas were associated with lower-quality data.
