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 service use and associated predisposing, enabling and need factors in community living adults and older adults across Canada
The authors utilized data from the CanPath COVID-19 health survey (May to December 2020) to conduct multivariate logistic regression analysis to determine the association between mental health service use (MHSU) and predisposing, enabling, and need factors — derived from Andersen’s model of healthcare-seeking behaviour — among five regional cohorts. Among the 45,542 adults in the study population, 6.3% of respondents reported MHSU and need factors were consistently associated with MHSU.
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.
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.
The BC Generations Project as a Tumor Tissue Resource for Cancer Research
BCGP is making significant strides in its utility as a high-quality tumor tissue research resource. The BC Cancer Registry recently implemented a text mining solution to allow BCGP to capture pathology reports for 100% of all newly diagnosed BCGP cancer cases!
Evaluation of Adiposity and Cognitive Function in Adults
Researchers sought to undercover the association between adipose tissue (amount and distribution) and cognitive scores. Using data from 9,189 participants, they found that higher visceral adipose tissue and body fat percentage correlated with increased vascular brain injuries and cardiovascular risk factors, as well as lower cognitive scores.
Patterns and determinants of adherence to colorectal cancer primary and secondary prevention recommendations in the BC Generations Project
Researchers assessed how 26,074 BCGP participants adhere to cancer prevention recommendations. They found that adherence to some behaviours was high, but clusters of poorer adherence were also highlighted. They suggested future work to evaluate targeted interventions to maximize adherence amongst lower socioeconomic status and health groups.
A large Canadian cohort provides insights into the genetic architecture of human hair colour
Researchers performed genome-wide association studies and meta-analyses to garner insight on regulatory mechanisms of hair colour variation and pigmentation biology. 12,996 genotyped CanPath participants were included in this study, along with their self-reported natural hair colour. The researchers fine-mapped significant loci throughout the genome, identifying multiple novel causal variants for hair colour.
