Factors associated with change in moderate or severe symptoms of anxiety and depression in community-living adults and older adults during the COVID-19 pandemic

Authors: Helen-Maria Vasiliadis, Jessica Spagnolo, Mary Bartram, Marie-Josée Fleury, Jean-Philippe Gouin, Sébastien Grenier, Pasquale Roberge, Grace Shen-Tu, Jennifer E Vena, Catherine Lamoureux-Lamarche , JianLi Wang

Researchers explored changes in moderate or severe symptoms of anxiety or depression (MSSANXDEP) from before to during the COVID-19 pandemic in Canada, and examined associated sociodemographic, economic, psychosocial, health behavior and lifestyle, and clinical factors. Data from 59,997 participants from the five established cohorts of the Canadian Partnership for Tomorrow’s Health (CanPath) were used. Analyses indicated that certain sociodemographic, economic, lifestyle, health behavior, psychosocial, and clinical factors were associated with remitted, incident, and persistent MSSANXDEP.

Factors associated with mental health service use during the pandemic: Initiation and barriers

Authors: Helen-Maria Vasiliadis, Jessica Spagnolo, Marie-Josée Fleury, Jean-Philippe Gouin, Pasquale Roberge, Mary Bartram, Sébastien Grenier, Grace Shen-Tu, Jennifer E. Vena, JianLi Wang

This study aimed to understand the factors associated with initiating new mental health service use (MHSU) during the COVID-19 pandemic, as well as distinguishing between different reasons for not seeking mental health services. The research found that several factors influenced MHSU, such as age, living situation, income, and health professional status. The study suggests the need for awareness campaigns targeting older adults to explain the importance of seeking treatment and for sensitizing health professionals to facilitate access to mental health care for individuals at risk of social isolation and lower socioeconomic status.

The evolution of SARS-CoV-2 seroprevalence in Canada: a time-series study, 2020-2023

Authors: Tanya J. Murphy, Hanna Swail, Jaspreet Jain, Maureen Anderson, Philip Awadalla, Lesley Behl, Patrick E. Brown, Carmen L. Charlton, Karen Colwill, Steven J.

O'Brien, Chantale Pambrun, Kimberly Skead, David A. Stephens, Derek R. Stein, Graham Tipples, Paul G. Van Caeseele, Timothy G. Evans, Olivia Oxlade, Bruce D. Mazer, David L. Buckeridge

This study used data from the COVID-19 Immunity Task Force, which includes CanPath data, to track the prevalence of SARS-CoV-2 antibodies in the Canadian population over the pre-vaccination period, the vaccine rollout, and the emergence of the Omicron variant. By March 2023, over three-quarters of the population had detectable antibodies, with the most substantial increases seen after the arrival of the Omicron variant. However, variations in immunity by age and geography highlight the importance of tailoring public health policies and clinical decisions to local patterns of population immunity, considering factors like potential antibody decline and the emergence of new variants that might evade immunity.

Development and external validation of partial proportional odds risk prediction models for cancer stage at diagnosis among males and females in Canada

Authors: Timofei Biziaev, Michelle L. Aktary, Qinggang Wang, Thierry Chekouo, Parveen Bhatti, Lorraine Shack, Paula J. Robson, Karen A. Kopciuk

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

Authors: Maryam Darvishian, Amina Moustaqim-Barrette, Philip Awadalla, Parveen Bhatti, Philippe Broet, Kelly McDonald, Rachel A. Murphy, Kimberly Skead, Robin Urquhart, Jennifer Vena, Trevor J. B. Dummer

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

Authors: Helen-Maria Vasiliadis, Jessica Spagnolo, Marie-Josée Fleury, Jean-Philippe Gouin, Pasquale Roberge, Mary Bartram, Sébastien Grenier, Grace Shen-Tu, Jennifer E. Vena, JianLi Wang

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

Authors: Jaclyn Parks, Millie Baghela, Parveen Bhatti

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

Authors: Maryam Darvishian, Jessica Chu, Jonathan Simkin, Ryan Woods, Parveen Bhatti

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

Authors: Rachel A. Murphy, Gabriela Kuczynski, Parveen Bhatti, Trevor J. B. Dummer

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

Authors: Robin Urquhart, Philip Awadalla, Parveen Bhatti, Trevor Dummer, Simon Gravel, Jennifer Vena, Riaz Alvi, Philippe Broet, Cynthia Kendell, Victoria Kirsh, Guillaume Lettre, Kimberly Skead, Grace Shen-Tu, Ellen Sweeney, Donna Turner

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.
